Coastal Land Use Plan
CHAPTER 1
1.0 Introduction
1.1 Purpose
This document establishes the Coastal Land Use Plan of the Local Coastal Program
of the City of Newport Beach, prepared in accordance with the California Coastal Act
of 1976. The Coastal Land Use Plan sets forth goals, objectives, and policies that
govern the use of land and water in the coastal zone within the City of Newport
Beach and its sphere of influence with the exception of Newport Coast and Banning
Ranch. Newport Coast is governed by the previously certified and currently
effective Newport Coast Local Coastal Program. Banning Ranch is a Deferred
Certification Area (DCA) due to unresolved issues relating to land use and the
protection of coastal resources (see Section 2.2.4).
1.2 Organization
The Coastal Act contains coastal resources planning and management policies that
address public access, recreation, marine environment, land resources,
development, and industrial development. The Coastal Land Use Plan addresses
these topics under the following chapters:
Land Use and Development. This chapter includes policies for topics in
Sections 30007, 30212.5, 30213, 30221 - 30223, 30235- 30236, 30250,
30252- 30253, 30255, 30260, 30262, 30600, 30610.5 of the Coastal Act.
Public Access and Recreation. This chapter includes policies for topics in
Sections 30210 - 30214, 30220 - 30224, 30234, 30234.5, 30244, and 30252
of the Coastal Act.
Coastal Resource Protection. This chapter includes policies for topics
covered in Sections 30230 - 30233, 30240, 30244, and 30251 of the Coastal
Act.
Each chapter is divided into sections and subsections. Each section or subsection
begins with the identification of the Coastal Act sections that are relevant to Newport
Beach, followed by a narrative of the local setting and policy direction adopted by the
City to address the requirements of the Coastal Act and a listing of specific policies.

1.3 General Policies
The following policies shall be applied to achieve the goals and objectives of the
Coastal Act in applying the policies of this Coastal Land Use Plan:
1. The policies of Chapter 3 of the Coastal Act (PRC Sections 30200 -
30263) shall be the guiding policies of the Coastal Land Use Plan.
2. When policies within the Coastal Land Use Plan conflict, such conflicts
shall be resolved in a manner which on balance is the most protective of
significant coastal resources.
3. Where there are conflicts between the policies set forth in this Coastal
Land Use Plan and those set forth in any element of the City's General
Plan, zoning, or any other ordinance, the policies of the Coastal Land Use
Plan shall take precedence. However, in no case, shall the policies of the
Coastal Land Use Plan be interpreted to allow a development to exceed
a development limit established by the General Plan or its implementing
ordinances.
1.4 The Coastal Act
In 1972, the United States Congress passed the Coastal Zone Management Act
(Title 16 U.S.C. 1451- 1464). The CZMA declared a national policy "to preserve,
protect, develop, and where possible, to restore or enhance, the resources of the
Nation's coastal zone for this and succeeding generations." The CZMA sought to
encourage and assist States to develop and implement management programs for
the use of coastal land and water resources, "giving full consideration to ecological,
cultural, historic, and esthetic values as well as the needs for compatible economic
development."
The Coastal Zone Conservation Act (Proposition 20) was approved by a 55.2
percent vote in 1972. It prohibited development 1,000 yards inland from California's
mean high tide without a permit from a regional or state coastal commission. It
created a temporary California Coastal Zone Conservation Commission and six
regional commissions to develop a statewide plan for coastal protection. The
California Coastal Plan was submitted to the Legislature in 1975 and led to the
passage of the California Coastal Act in 1976.

I he Coastal Act established the
permanent California Coastal
Commission. The Coastal
Commission's mandate is to
protect and enhance the
resources of the coastal zone
mapped by the Legislature.
Coastal Commission
membership is composed of
twelve voting members,
appointed equally by the
Governor, the Senate Rules
Committee, and the Speaker of
the Assembly. Half of the voting
commissioners are locally
elected officials and half are
representatives of the public at
large. The Coastal Commission
also has four ex officio (non-
voting) members representing
the Resources Agency the
Business, Transportation and Housing Agency, the Trade and Commerce Agency
and the State Lands Commission.
The Legislature found that "to achieve maximum responsiveness to local conditions,
accountability, and public accessibility, it is necessary to rely heavily on local
government and local land use planning procedures and enforcement." Therefore,
implementation of Coastal Act policies is accomplished primarily through the
preparation of a Local Coastal Program (LCP), reviewed and approved by the
Coastal Commission. An LCP typically consists of a land use plan and an
implementation plan. The land use plan indicates the kinds, location, and intensity of
land uses, the applicable resource protection and development policies, and, where
necessary, a listing of implementing actions. The implementation plan consists of
the zoning ordinances, zoning district maps, and other legal instruments necessary
to implement the land use plan. Any amendments to the certified LCP will require
review and approval by the Coastal Commission prior to becoming effective.
After certification of an LCP, coastal development permit authority is delegated to the
appropriate local government. The Coastal Commission retains original permit
jurisdiction over certain specified lands, such as submerged lands, tidelands, and
public trust lands, and has appellate authority over development approved by local
government in specified geographic areas. In authorizing coastal development
permits, the local government must make the finding that the development conforms
to the certified LCP.

1.5 The City of Newport Beach
History
In order to fully understand the relationship between the Coastal Land Use Plan and
the community, it is necessary to understand the community and the historical events
that have influenced it. The history of Newport Beach begins with the bay. It is the
story of how natural forces shaped the land and coast and how people responded to
these changes.
It is believed that Newport Bay formed about 300,000 years ago when a precursor of
the Santa Ana River flowed into the northern end of the bay and carved a deep
canyon. Rising sea levels submerged the bay until about 15,000 to 25,000 years
ago. When the bay reemerged, the Santa Ana River, as it did throughout its history,
had shifted across the coastal plain and now flowed into the ocean at Alamitos Bay.
10,000 to 12,000 years ago, aboriginal
hunters and gatherers were first drawn to
this area by the rich bounty of the bay
and ocean. These original inhabitants
supplemented their diet with a variety of
meat from marine resources, including
shellfish, fish, and birds and probably
ventured out into the ocean in rafts to fish
for Sheepshead, Blacksmith, and Giant
Kelpfish. The most recent native people
were the Tongva (Gabrielinos) and the
Acjachemem (Juanenos), who lived in
small villages around the bay until the
beginning of the Mission period in the
1770's.
Tongva millingstone
During the Mission period, the hills above the bay were part of a vast open cattle
range of the Mission San Juan Capistrano. Early Spanish names for the bay were
Bolsa de Quigara (bay with high banks) or Bolsa de Gengara, in reference to a
nearby Indian village. After Mexico gained independence from Spain in 1831, the
mission lands were broken up and redistributed through land grants. In 1837, the
bay became a part of Rancho San Joaquin under the ownership of Jose Andres
Sepulveda. Floods and droughts caused Sepulveda to sell the ranch in 1864 and it
eventually became a part of the expansive Irvine Ranch.
The bay at that time was open to the ocean and part of a large estuary that stretched
from Huntington Beach to Corona del Mar. In 1825, unusually heavy floods again
shifted the mouth of the Santa Ana River to the southeast of the Huntington Beach
mesa. Sand carried by the river began to form a peninsula. Over the next thirty
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
1 -4
years, the peninsula made steady progress in a southeasterly direction. By 1857,
the eastern tip had reached to approximately where Bay Island is today. Floods
during the winter of 1861 -62 extended the peninsula to the present harbor entrance.
This barrier beach forced the Santa Ana River to flow parallel to the coast. The
accretion of silt made the bay shallower and spread marsh vegetation.
In the late 1860's, the bay was used as a landing to load hides, tallow, hay and other
goods for export. In September 1870, Captain Samuel S. Dunnells' steamer
Vaquero ventured into the bay to offload a cargo of lumber and shingles. Captain
Dunnells soon established "Newport Landing" by constructing a small wharf and
warehouse near the west end of the present Coast Highway /Newport Bay Bridge.
James McFadden and his younger brother Robert acquired the landing in 1875 and
for the next nineteen years operated a thriving commercial trade and shipping
business. However, the bay was not yet a true harbor and sand bars and a
treacherous bay entrance caused the McFadden Brothers to move the shipping
business to the oceanfront by constructing a large pier on the sand spit that would
become the Balboa Peninsula. The site was ideal because a submarine canyon
(Newport Submarine Canyon), carved along with Newport Bay by the ancient Santa
Ana River, provided calm waters close to the shore. McFadden Wharf was
completed in 1888 and was connected by rail to Santa Ana in 1891. For the next
eight years, the McFadden Wharf
area was a booming commercial and
shipping center and a company town
began to grow. However, in 1899,
the Federal Government allocated
funds for major improvements to a
new harbor at San Pedro, which
would become Southern California's
T ! : major seaport. The McFadden Wharf
`r and railroad was sold to the Southern
Pacific Railroad that same year,
signaling the end of Newport Bay as
• a commercial shipping center.
1875 smey map of Newport Bay In 1902, James McFadden sold his
Newport townsite and about half of the Peninsula to William S. Collins, who saw
Newport Bay's resort and recreation potential. Collins took on Henry E. Huntington
as a partner in the Newport Beach Company. Huntington had acquired the Pacific
Electric railway system and used it to promote new communities outside of Los
Angeles. In 1905, the Pacific Electric "Red Cars" were extended to Newport and
then to Balboa the following year. Also in 1906, Collins began dredging a channel on
the north side of the bay and deposited the sand and silt on tidelands that would
become Balboa Island. Between 1902 and 1907, many of Newport Beaches'
waterfront communities were subdivided, including West Newport, East Newport,

Coastal Land Use Plan

Bay Island, Balboa, and Balboa Island. This established the grid system of small lots
and narrow streets and alleys that still exists today in these areas.
In 1906, the City of Newport Beach, consisting
of West Newport and Balboa Peninsula,
incorporated. In 1916, most of Balboa Island
was annexed, followed by Newport Heights in
1917, Corona del Mar in 1924, and the
balance of Balboa Island in 1927. In 1923, the
dredging and filing of mud Flats that would
become Lido Island began. At this time,
Newport Beach was still a beach town, with
most of the homes being constructed as
beach cottages and second homes used for
vacations. However, public safety concerns
would move Newport Beach to embark on a
series of projects to protect and improve the
harbor and ultimately lead to the next stage in
the City's development.
Newport Beach circa 1910
At that time, the channels in the bay were narrow, shallow, and tortuous. Two
massive Floods in December 1914 and January 1916 filled the harbor and beaches
with silt and debris. This and an increasing number of drownings at the harbor
entrance prompted Newport Beach voters to approve funds to build the west jetty. In
1919, Orange County voted for funds to extend the jetty and build a dam to divert the
Santa Ana River from the bay and Flow directly into the ocean west of the City. The
harbor improvements turned a small colony of fishermen into a major industry. In
the1920's the sport fishing and commercial fishing would become the major source
of income in Newport Beach. In 1921, the first of four commercial fish canneries was
built on the Rhine Channel. The boatyard industry also began to Flourish.
The great increase in the number of commercial and recreational boats in the 1920s
led to calls for further harbor improvements. Also, the consensus gradually changed
from development of a commercial harbor to a recreational harbor. In 1928, Newport
Beach voters approved funds for work on the west and east jetties. In 1933, a
federal grant and matching funds from an Orange County bond measure provided
funds to extend the jetties and dredge the entire Lower Newport Bay, On May 23,
1936, Newport Harbor was dedicated. The completion of the harbor improvements
increased recreational and commercial boating activity. The South Coast Shipyard
produced all types of pleasure craft. With the United States entry into World War II,
the boatyards quickly shifted to the wartime production. South Coast and the new
Lido Shipyard produced minesweepers, sub chasers, and other military vessels. By
the end of the war, the summer beach resort town had become a city of 10,000
people.

The postwar boom in Southern California led to the next stage in the City's
development. The Irvine Company began to open some of its vast land holdings
east of the City to residential development. During the 1950's the City annexed over
4,382 acres, more than tripling its land area. In 1960, the City had a population of
26,565 people. The 1960's saw the development of major employment, commercial,
and educational centers in Orange County. The City annexed another 2,280 acres,
including the Newport Dunes and the future sites of Newport Center and Fashion
Island. In 1970, the City's population had reached 49,442 people.
The expansion and development of the City led to a period of introspection in the
1970's. In 1969, a citizens committee completed work on a set of community goals
titled Newport Tomorrow, which served as the basis for the City's 1973 General Plan.
Newport Tomorrow also served as a catalyst for a series of special studies, which
resulted in new development controls.
In 1970, the Lower Newport Bay Civic District study began to analyze development
around the lower bay, including height limits, the preservation of marine service
facilities, public access, and view corridors. The study resulted in the adoption of the
Shoreline Height Limitation Ordinance in 1972, which established new height and
bulk restrictions around the bay. Height limits along Pacific Coast Highway and other
commercial areas were lowered from 85 to 26 feet. Residential development
standards for Corona del Mar, Balboa Island, West Newport, and the Balboa
Peninsula followed in 1973 and 1974, which set stricter Floor area and height limits
and higher off -street parking and open space requirements.
A proposed land exchange
between the County of Orange
and the Irvine Company cleared
the way for the development of
the Upper Newport Bay with
residential uses and marinas in
the early 1960's. Newport
Beach residents began a
movement to preserve the Upper
Bay, first winning local
government support, then at the
County, then at the State. In
1973, an appellate court ruled
that a proposed land exchange
Upper Newport Bay Grca 1952 was unconstitutional. In 1974, a
committee composed of Federal, State, and local agencies and interested members
of the community produced a plan that recommended preservation of the Upper Bay.
The Upper Newport Bay Ecological Reserve (Upper Newport Bay Marine Park) was
created in 1975 as result of the purchase of 527 acres of land in and around the bay
CITY COUNCIL DRAFT 1 Local Coastal Program

from the Irvine Company and the transfer of 214 acres of tidal wetlands from the
County of Orange to the State.
The City continued to expand and
develop in the 1980's and 1990's, albeit
at a slower pace. The City's population
was 65,283 in 1980, and increased to
66,643 in 1990. Land use and
development policies continued to be
refined. In 1988, comprehensive
amendments to Land Use and
Circulation Elements of the General
Plan were adopted to establish
reasonable density and intensity limits,
allow for modest growth, and to better
correlate land uses with the circulation
system. Specific plans were adopted
for the older commercial districts on the
Balboa Peninsula, including Cannery
Village, McFadden Square, and Balboa
Village. By the year 2000, the
population had reached 70,032.

At the beginning of the 21'` Century, Newport Beach is a community of 75,662
people covering 25.4 square miles, including 2.5 square miles of bay and harbor
waters. The City has over 30 miles of bay and ocean waterfront. Over 63 percent of
the City is in the coastal zone.
While Newport Beach is no longer a sleepy little beach town, the bay and beach
continue to play an important role in the community's character and economy.
Newport Harbor is the largest small craft harbor in the United States with over 9,000
boats at 2,119 commercial slips and side ties, 1,221 bay moorings, and 1,230 piers.
Beach attendance averages 9.4 million people annually.
Newport Beach continues to be a major visitor destination. In FY 2001, the City
received 7.2 million visitors (people other than those who reside or work here). Over
80 percent of the City's visitors are here for purposes of leisure. The City has 16
hotel properties with 2,977 rooms and 535 seasonal housing units. However, the
vast majority are day visitors.

CHAPTER 2
2.0 Land Use and Development
2.1 Land Use
The Coastal Land Use Plan was derived from the Land Use Element of the General
Plan and is intended to identify the distribution of land uses in the coastal zone. The
Land Use Element may contain more precise development limits for specific
properties. Should a conflict exist, the land use intensity or residential density limit
that is most protective of coastal resources shall take precedence. However, in no
case, shall the policies of the Coastal Land Use Plan be interpreted to allow a
development to exceed a development limit established by the General Plan or its
implementing ordinances.
2.1.1 Land Use Designations
Policy 2.1.1 -1 The following land use designations establish the type, density and
intensity of land uses within the coastal zone. If there is a conflict between the
development limits of the Land Use Element and the Coastal Land Use Plan, the
provision that is most protective of coastal resources shall take precedence.
However, in no case, shall the policies of the Coastal Land Use Plan be interpreted
to allow a development to exceed a development limit established by the General
Plan or its implementing ordinances.
Residential
Estate Residential (RE). The RE designation is intended to provide for very low -
density single - family detached residential development on large lots. Residential
density ranges from 0.5 to 2.5 units per gross acre.
Very Low Density Residential (RVL). The RVL designation is intended to provide
primarily for very low- density single - family detached residential development.
Residential density ranges from 2.6 to 4.5 units per gross acre.
Low Density Residential (RL). The RL designation is intended to provide primarily
for low- density single - family detached residential development. Residential density
ranges from 4.6 to 6 units per gross acre.
Medium Density Residential (RM). The RM designation is intended to provide for
a range of residential development types, including single - family (attached and
detached), two- family, and multi - family residential.

Planning Study Area 5 (Balboa Bay
Club). The Balboa Bay Club is located on
Coast Highway between the Orange
Coast College David A. Grant Collegiate
Rowing Centerand the Bayshores
community. The property consists of
approximately 12.6 acres of State
tidelands held in trust by the City of
Newport Beach and leased to the Balboa
Bay Club, Inc. It is currently developed
Balboa Bay Gub with many uses, including visitor - serving,
recreational, boating, restaurant and
banquet, and residential facilities. The site is designated for a mixture of
Recreational and Marine Commercial and High Density Residential A and is
allowed a Floor area ratio of 0.5. Residential development is allowed in
conjunction with commercial development up to a maximum total Floor area
ratio of 1.0 and 144 dwelling units.
The use of tidelands for a private club and for private residences is in conflict
with the public trust doctrine. Assembly Bill 3139 (Chapter 728, Statutes of
1994) provided for redevelopment of the private club portion of the property to
allow full public access and the continuation of the residential uses to
December 31, 2044 (see Section 2.6).

The Newport Dunes provides a variety of recreational and visitor - serving
uses. Protection, and if feasible, expansion and enhancement, of the diversity
of these uses should be a part of any new development application.
Particular attention should be given to provision of lower cost uses.
The Newport Dunes is located on the Upper Newport Bay and surrounded by
coastal bluffs. Any application for new development must given special
consideration to the protection of the water quality of the bay and adjacent
natural habitats. Any new development should be designed and sited to
minimize impacts to public views of the water and coastal bluffs.
2.1.2 Coastal Land Use Plan Map
The Coastal Land Use Plan Map depicts the land use designation for each property
and is intended to provide a graphic representation of policies relating to the location,
type, density, and intensity of all land uses in the coastal zone.
Policy 2.1.2 -1. Land uses and new development in the coastal zone shall be
consistent with the Coastal Land Use Plan Map and all
applicable LCP policies and regulations.

2.2 General Development Policies
2.2.1 Location of New Development
Coastal Act policies related to the location of new development that are relevant to Newport
Beach include the following:
30250 (a). New residential, commercial, or industrial development, except as otherwise provided in this division, shall be
located within, contiguous with, or in close proximity to, existing developed areas able to accommodate it or, where such
areas are not able to accommodate it in other areas with adequate public services and where it will not have significant
adverse effects, either indKidually or cumulatively, on coastal resources. In addition, land divisions, otter than leases for
agricultural uses, outside existing developed areas shall be permited only where 50 percent of the usable parcels in the area
have been developed and the created parcels would be no smaller than the average size of surrounding parcels.
The Coastal Act provides for the protection of coastal resources by requiring that
new development be located in areas in close proximity to existing development with
available public services to minimize the impacts associated with the extension of
infrastructure and services. Most of the areas of Newport Beach's coastal zone were
developed during the first half of the 2& Century. Therefore, new development
within the coastal zone will occur in the form of redevelopment or infill development
within or adjacent to existing developed areas. These areas have adequate public
services or are capable of having public services extended or expanded without
significant adverse effects on coastal resources.
The only exception is the 505 -acre Banning Ranch property. Save for oil field
facilities, Banning Ranch is undeveloped, but is contiguous to the developed areas of
Newport Beach, Costa Mesa, and Huntington Beach. Banning Ranch is designated
as a deferred certification area due to unresolved land use and resource protection
issues (see Section 2.2.4).
Policies:
2.2.1 -1. Continue to allow redevelopment and infill development within
and adjacent to the existing developed areas in the coastal
zone subject to the density and intensity limits of the Coastal
Land Use Plan.
2.2.1 -2. Require new development be located in areas with adequate
public services or in areas that are capable of having public
services extended or expanded without significant adverse
effects on coastal resources.

2.2.2 Coastal Development Review
Coastal Act policies related to development review that are relevant to Newport Beach
include the following:
30600 (a). Except as provided in subdivision (e), and in addition to obtaining any other permt required by law from any local
government or from any state, regional, or local agency, any person, as defined in section 21066, wishing to perform or
undertake any development in the coastal zone, ode than a facility subject to section 25500, shall obtain a coastal
development permit.
30600 (d). After certification of its local coastal program or pursuant to the provisions of Section 30600.5, a coastal
development permit shag be obtained from the local government as provided for in Section 30519 or section 30600.5.
In order to ensure that development
within the coastal zone is consistent
with the LCP, the City will require a
coastal development permit prior to
commencement of any development in
the coastal zone, with the exceptions of
developments in areas where the
Coastal Commission retains permit
jurisdiction, developments determined
to be categorically excluded according
to the categories and standards
established by the Coastal
Commission, and developments
determined to be excluded from the
i'
Beachfrom residential development on the Balboa Peninsula.
coastal development permit requirements pursuant to Public Resources Code
Section 30610.
Policies:
2.2.2 -1. After certification of the LCP, require a coastal development permit for all
development within the coastal zone, subject to exceptions provided for
under the Coastal Act as specified in the LCP.
2.2.2 -2. Incorporate coastal development permit procedures into the
implementation plan to ensure that all public and private development in
the coastal zone is consistent with the LCP.
2.2.2 -3. Prior to approval of any coastal development permit, the City shall make
the finding that the development conforms to the policies and
requirements contained in the Coastal Land Use Plan.

2.2.3 Exclusion Areas
Excerpts from specific Coastal Act sections related to exclusion areas that are relevant to
Newport Beach include the following:
30610 Notwithstanding any other provision of this division, no coastal development permit shall be required pursuant to this
chapter for the following types of development and in the following areas:
(e) Any category of development or any category of development within a specifically defined geographic area, that the
commission, after public hearing, and by two-thirds vote of is appointed members, has described or identified and with
respect to which the commission has found that there is no potential for any significart adverse effect ether individually or
cumulatively, on coastal resources or on public access to, or along, the coast and, where the exclusion precedes certification
of the applicable local coastal program, that the exclusion will not impair the ability of local government to prepare a local
coastal program.
30610.5 Urban land areas shag, pursuant to the provisions of this section, be excluded from the permit provisions of this
chapter.
(b) Every exclusion granted under subdivision (a) of tins section and subdivision of (e) Section 30610 shall be subject to
temps and conditions to assure that no significant change in density, height or nature of uses will occur without Gather
proceedings under this division, and an order granting an exclusion under subdivision (e) of Section 30610, but not under
subdivision (a) of this section may be revoked at any time by the commission, t the cons iitons of exclusion are violated. Tide
and submerged land beaches, and Ids immediately adjacent to the inland extent of any beach, or of the mean high tide line
of the sea where there is no beach, and all lands and waters subject to the public mist shall not be excluded under either
subdivision (a) of this sexton or subdivision (e) of section 30610.
Section 30610 (e) of the Coastal Act provides for a category of development, or a
category of development within a specifically defined geographic area, to be
excluded from the coastal development permit provisions of the Coastal Act provided
there is no potential for any significant adverse effect, either individually or
cumulatively, on coastal resources or on public access to, or along, the coast.
Residential Areas
• On June 14, 1977, the Coastal Commission adopted Categorical Exclusion Order E-
• 77 -5, at the request of the City of Newport Beach pursuant to Section 30610 (e) of
the Coastal Act. The categorical exclusion is for the demolition and /or construction
• of all single - family and two - family residences and their appurtenant facilities in most
• residentially -zoned districts within the City of Newport Beach within the coastal zone.
• The categorical exclusion, however, does not include the first row of lots adjacent to
the beach, bay or wetlands nor is the categorical exclusion applicable to major
• undeveloped residential sites within the coastal zone, Planned Community zoned
• districts or gated communities within the City. In Resolution No. 9190, the City
• Council found and determined that the exclusion applies only to Balboa Island, the
• Balboa Peninsula, Cameo Highlands, Cameo Shores, Corona del Mar, Corona
Highlands, Irvine Terrace, Lido Isle, Shorecliffs, the Upper Bay and West Newport.
• Pursuant to Section 13249 (b) of the California Code of Regulations, a categorical
• exclusion order automatically terminates upon the effective date of the delegation of

•
development review authority to a local government. Therefore, Categorical
Exclusion Order E -77 -5 will terminate when the LCP is certified and adopted.
The categorical exclusion was adopted in recognition that the residential areas in
question contained little vacant land and that new development consisted primarily of
the conversion of single - family dwellings to two- family dwellings and the replacement
and improvement of existing single - family and two- family residences. These
residential areas consist of well - established neighborhoods. Development in the 27
years since the adoption of the categorical exclusion has continued to be in the form
of redevelopment or infill projects. The permitted residential unit type and maximum
density of the Coastal Land Use Plan reflect the predominant form of development in
these areas. Residential floor areas and building heights have been strictly
controlled since the early 1970's to insure that the scale, size, and character of new
development is compatible with existing development in the surrounding area.
Therefore, the City should seek a new categorical exclusion for these residential
areas concurrently with certification of the LCP.
Commercial Areas
The Corona del Mar commercial area is
generally located along Coast Highway
between Avocado Street (including the
southwest corner) and Hazel Drive.
Only the south side of Coast Highway is
located within the coastal zone. It has
been zoned for commercial uses since
1936 and developed as a business
district for over 75 years. The
commercial area is completely
urbanized and new development is
limited to a maximum floor area to land
area ratio of 0.75. Unlike other coastal
commercial areas that largely serve the Coast Highway in Corona del Mar
visitor market, Corona del Mar has the broadest base of local- serving retailers. The
portion of the Corona del Mar commercial area located in the coastal zone is located
1,000 to 2,500 feet from the shoreline. Given this commercial area's considerable
distance from the shoreline and minimal use by coastal zone users, there is no
potential for significant adverse effects, either individually or cumulatively, on public
access to the coast or on coastal resources. Therefore, the City should seek a
categorical exclusion for this commercial area concurrently with certification of the
LCP.

2.2.4 Deferred Certification Areas
Deferred Certification Area (DCA) refers to an area which has not been officially
segmented for purposes of LCP preparation and where both the land use plan and
implementation plan have been deferred to some future date in order to avoid delay
in certifying the balance of the LCP. The Coastal Commission retains permit
jurisdiction in all deferred certification areas.
Banning Ranch. Banning
Ranch consists of 505 acres
located north of the Semeniuk
Slough and Coast Highway
West and east of the Santa Ana

E -144. These operations consist of 483 producing, idle, injection, and abandoned
well sites and related service roads, pipelines, storage, and other facilities. The
property contains a number of sensitive habitat types, including southern coastal
bluff scrub, alkali meadow, southern coastal salt marsh, southern black willow forest,
coastal brackish marsh, and vernal pools. The property also contains steep coastal
bluffs along the southern and western edges of the mesa. The bluff faces have been
eroded in some areas to form a number of gullies and ravines. Future land uses for
Banning Ranch are currently under review as part of a comprehensive update of the
City of Newport Beach General Plan.
Banning Ranch shall remain a deferred certification area until such time as the future
land uses for the property are resolved and policies are adopted to address the
future of the oil and gas operations and the protection of the coastal resources on the
property.
Policies:
2.2.4 -1. Designate the Banning Ranch property as an area of deferred
certification until such time as the future land uses for the property are

2.2.5 Nonconforming Structures and Uses
As one of the older coastal communities, Newport Beach has land uses and
improvements that do not conform to the standards of the LCP or other policies and
regulations that have been adopted over the years. This section is intended to
establish policies to limit the expansion of nonconforming structures and uses to the
maximum extent feasible and to bring these structures and uses into conformity in a
timely manner, without infringing upon the constitutional rights of property owners.
Policies:
2.2.5 -1. Legally established nonconforming structures may be maintained and
repaired. Interior alterations, structural alterations, and additions shall
be limited as follows.
A. Nonstructural interior alterations shall not exceed 50 percent of the
replacement cost of a nonconforming structure.
B. Alteration of more than 25 percent of the structural elements of a
nonconforming structure shall be subject to discretionary review
and approval by the City.
C. Additions shall be permitted to structures that are legally
nonconforming due to reasons other than for parking, open space,
floor area, or building bulk. Additions of more than 25 percent of
the gross floor area of a nonconforming structure shall be subject to
discretionary review and approval by the City.
D. No alternations or additions to a nonconforming structure shall
increase the degree of the structure's nonconformity.
2.2.5 -2. The enlargement or intensification of legally established
nonconforming uses shall be limited to only those uses normally
permitted by right or by the approval of a use permit, but which were
made nonconforming by additional regulations of the district in which
they are located. Such enlargement or intensification shall be subject
to discretionary review and approval by the City and shall not increase
the degree of the use's nonconformity.

2.3 Visitor - serving and Recreational Development
Coastal Act policies related to visitor- serving and recreational development that are relevant
to Newport Beach include the following:
30213. Lower cost visitor and recreational facilities shag be protected, encouraged, and, where feasible, provided.
Developments providing public recreational opportunities are preferred.
30221. Oceanfront land suitable for recreational use shag be protected for recreational use amt development %"ass presert
and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property
is already adequately provided for in the area.
30222. The use of private lands suitable for visitor - serving commercial recreational facilities designed to enhance public
opportunities for coastal recreation shell have priority over private residential, general industrial, or general commercial
development, but not over agilctiare or coastal -dependent industry.
30223. Upland areas necessary to support coastal recreational uses shall be reserved for such uses, where feasible.
30250 (c). Visitor-serving facilities that cannot feasibly be located in edsting developed areas shelf be located in edsting
isolated developments or at selected points of attraction for visitors.
2.3.1 Commercial
Newport Beach has thirty-seven distinct
commercial areas within the coastal zone. These
areas range from small strip commercial areas to
large hotel complexes. Most of the coastal zone's
commercial development is in the City's older
business districts. These business districts were
originally developed to serve harbor - related
businesses and industries and to serve the City's
original residential areas. Over the years, portions
of these business districts have been redeveloping
to visitor - oriented retail, water - related businesses,
recreational uses, and mixed
commercial /residential projects. The Coastal Land
Use Plan allows for the continuation of this trend,
while continuing to provide businesses that serve
the needs of residents and are essential to the
harbor operations.
Oceanfront Boardwalk near Newport Pier
Visitor - serving and recreational activities are an important part of the character and
economy of Newport Beach. In 2003, Newport Beach had 14 hotels, motels,
timeshares, and bed & breakfast inns in the coastal zone and 18 citywide. These
facilities provide a total of 2,287 rooms in the coastal zone and 3,520 rooms citywide.
In FY 2001, Newport Beach received 7.2 million visitors (people other than those
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan

who reside or work here). Over 80 percent of the City's visitors are here for
purposes of leisure and the vast majority are day visitors.
Other visitor - serving and recreational
facilities located within commercial areas
include restaurants, snack bars, boat
rentals, sports equipment rentals, boat
tours of the harbor, boat launching facili-
ties, amusement and recreation facilities,
and numerous shops selling specialized
merchandise. Many of these facilities
have become tourist attractions in their
own right, such as the Balboa Pavilion,
the Fun Zone, Balboa Ferry, the entire
Marine Avenue area on Balboa Island,
and certain restaurants.
Edgewater boardwalk in Balboa Village
Most of the lands suitable for visitor - serving and recreational uses are in the
commercial areas surrounding and adjacent to the west end of Newport Harbor.
Most of the waterfront land in this area has been designated for recreational and
marine uses. Also, individual hotel and motel sites on the Balboa Peninsula, in West
Newport, and adjacent to the Upper Newport Bay and other open space areas are
designated for visitor - serving uses.
A 2002 retail commercial market analysis verifies that the City's main coastal zone
commercial areas largely serve the visitor market. In Balboa Village, Balboa Island,
McFadden Square, and Mariner's Mile, visitors (people from outside each study
area) account for the vast majority of retail sales. On Balboa Island, retail sales are
dominated by apparel stores, specialty retail stores, and restaurants, which generally
sell to tourists and other non - residents. In McFadden Square and Balboa Village,
which are adjacent to beaches, restaurants are the single most prominent retail sales
category, followed by apparel and sporting goods stores that primarily cater to
visitors.

The lower percentage of retail spending by visitors in Lido - Cannery is due primarily
to the presence of two large grocery stores that serve West Newport, Lido Isle, and
the Balboa Peninsula and constitute over half of the retail sales. The extremely high
percentage of retail spending by visitors in Mariner's Mile is due primarily to the high
concentration of restaurants, entertainment boat operations, automobile and boat
dealers, and marine - related retail stores.
While the coastal zone commercial areas are
heavily oriented to the visitor market, some
commercial areas are also underperforming
economically. McFadden Square and Balboa
Village have sales per square foot that are below
national averages in nearly every retail category.
Many businesses have to drastically reduce their
hours of operation or close down completely
during the winter months. This often gives an
impression of economic stagnation and can
detract from the ability of the commercial district to
attract customers. Therefore, these areas should
continue to be permitted a wider range of
commercial uses in order to maintain year- around
economic viability.
While a high proportion of spending in Corona del
McFadden Square shops on the Oceanfront Mar Is by visitors, many of the categories
Boardwalk represented are not necessarily visitor - oriented.
About half of the retail sales are generated by grocery stores and furniture, home
furnishings, and home improvement stores. This indicates that much of the retail
spending in Corona del Mar is from customers from neighboring communities, but
who are not necessarily coastal zone visitors. This is to be expected since the
portion of the Corona del Mar commercial area located in the coastal zone is 1,000
to 2,500 feet from the shoreline.
Policies:
2.3.1 -1. Permit visitor - serving retail and eating and drinking establishments in
all commercially designated areas.
2.3.1 -2. Continue to provide waterfront- oriented commercial uses, including
eating and drinking establishments and recreation and entertainment
establishments, as a means of providing public access to the
waterfront.

2.3.1 -3. On land designated for visitor - serving and /or recreational uses, give
priority to visitor - serving commercial recreational facilities designed to
enhance public opportunities for coastal recreation over other
commercial uses, except for agriculture and coastal- dependent
industry.
2.3.1 -4. Protect oceanfront land designated for visitor- serving and /or
recreational uses for recreational use and development unless present
and foreseeable future demand for public or commercial recreational
activities that could be accommodated on the property is already
adequately provided for in the area.
2.3.2 Open Space and Tidelands /Submerged Lands
Newport Beach's open space designated
areas in the coastal zone include beaches,
parks, golf courses, yacht clubs, and
environmentally sensitive habitat areas and
other natural resources. These areas
provide a wide range of recreational and
visitor - serving uses and facilities.
Nearly all of the oceanfront land, including
the entire Balboa Peninsula, is public beach.
In total, there are over 276 acres of public
beaches on the shoreline. There are also
approximately 415 acres of recreational and
view parks on or adjacent to the shoreline.
Rowing in the Upper Newport Bay
Tidelands and submerged lands are State lands held in trust by the City of Newport
Beach, the County of Orange or State resource agencies. These lands are subject
to the public trust doctrine and are limited to public trust uses, such as navigation,
fisheries, commerce, public access, water - oriented recreation, open space and
environmental protection. The waters of Newport Bay and of the Pacific Ocean
adjacent to Newport Beach are used for a wide variety of recreational activities,
including boating, diving, excursions, fishing, kayaking, paddle boarding, parasailing,
rowing, sailing, surfing, swimming, and wind surfing. Development in the form of
marinas, moorings, piers, and equipment rentals provide recreational opportunities
and access to the water.
The Newport Dunes Aquatic Park is on 100 acres of State tidelands property held in
trust by the County of Orange. The park is leased to a private operator and provides

a recreational vehicle park, campgrounds, a marina, boat launching and storage
facilities, beach day use facilities, and a swimming lagoon.
Policies:
2.3.2 -1. Continue to use public beaches for public recreational uses and
prohibit commercial uses on beaches that interfere with public access
and enjoyment of coastal resources.

2.3.3 Lower Cost Visitor and Recreational Facilities
Camping at Newpon Dunes
Newport Beach currently provides a variety
of overnight visitor accommodations in all
price ranges. In 2003, Newport Beach had
14 hotels, motels, timeshares, and bed &
breakfast inns in the coastal zone providing
2,287 rooms. Peak summer rates ranged
from $69 to $750 per night. The Newport
Dunes provides a 406 -space recreational
vehicle park, with tent camping permitted.
In 2003, peak summer rates ranged from
$42 to $139 per night.
A significant number of single - family homes, condominiums, and apartments serve
as overnight visitor accommodations. Each year, hundreds of dwelling units in
coastal zone residential areas are rented on a weekend, weekly or monthly basis.
Most of these dwelling units have beach or bay front locations or are located within
walking distance to the water. Because they typically provide additional sleeping
accommodations and fully equipped kitchens, they provide an accommodation
option comparable to or less expensive than staying in hotels and going out to
restaurants for meals. Particularly for large families, these dwelling units provide an
affordable alternative to hotels and motels. In 2003, weekly rates are as low as
$900. The City requires short-term lodging permits for dwelling units rented for 30
days or less to insure that overcrowding and public nuisances do not result in
adverse impacts to residential areas, coastal access, and coastal resources (see
Section 2.7). In 2003, the City issued over 800 short-term lodging permits.
The City provides approximately 360 acres of public beaches and parks in the
coastal zone, which are available free of charge. Also, the County's Upper Newport
Bay Nature Preserve and the day use facilities at the County's Newport Dunes
Aquatic Park are available free of charge. These areas offer a variety of free or
lower cost recreational opportunities and are discussed further in Section 3.2.
The City, County, and private organizations also provide several coastal - related
educational and interpretative facilities and programs that are either free or have a
nominal charge. These include the Muth Interpretative Center in the Upper Newport
Bay Nature Preserve, the Back Bay Science Center on Shellmaker Island, the
Newport Aquatic Center at North Star Beach, and the Newport Harbor Nautical
Museum.

2.4 Coastal - dependent/related Development
Coastal Act policies related to coastal-dependent and coastal- related development that are
relevant to Newport Beach include the following:
30255. Coastal -dependent developments shall have priority over odw developments on or near the shoreline. Except as
Provided elsewhere in this division, coastal-dependent developments shall not be sited in a wetland. When appropriate,
coastal-related developments should be accommodated within reasonable proximity to the coastal -dependent uses they
supper
2.4.1 Commercial
Newport Harbor supports a wide range of coastal -
dependent and coastal - related commercial uses.
These include passenger /sightseeing boats,
passenger - fishing boats, boat rentals and sales,
recreational equipment rentals, entertainment
boats, boat/ship repair and maintenance, and
harbor maintenance facilities. These uses play an
important role in the character of the harbor and
provide the services necessary to sustain one of the
world's great small boat harbors.
Coastal- dependentl- related
Coastal - dependent refers to a
development or use that requires a site on,
or adjacent to, the sea to be able to
function at all. Coastal - related refers to a
development or use that is dependent on a
coastal - dependent development or use.
Over the past 20 years, a number of
marine - related businesses and
industries in Newport Beach have
moved to inland areas. This is
reflective of a regional trend, largely
due to increased environmental
regulation in California affecting
fiberglass manufacturing processes,
as well as real estate price inflation
in coastal communities.
The Recreational and Marine
Commercial (CM) designation is the
primary method of providing for the
Basin Marine Shipyard continuation of coastal- dependent
and coastal- related commercial uses
on or near the bay. The CM designation is applied to areas that have historically
provided marine - related businesses and industries and visitor - serving and
recreational areas.

2.4.1 -3. Design and site new development to avoid impacts to existing coastal -
dependent and coastal - related developments. When reviewing
proposals for land use changes, give full consideration to the impact
on coastal- dependent and coastal - related land uses including not only
the proposed change on the subject property, but also the potential to
limit existing coastal- dependent and coastal - related land uses on
adjacent properties.
2.4.1 -4. Maintain the Recreational and Marine Commercial designation in
areas on or near the bay to encourage a continuation of coastal -
dependent and coastal - related uses.
2.4.1 -5. Encourage and maintain facilities that serve marine - related businesses
and industries unless the demand for such facilities no longer exists.
2.4.2 Public Facilities
Kerckhoff Marine Laboratory in Corona del Mar
Lands designated for public facilities
that are on or adjacent to the
shoreline are primarily used for
public parking, public safety facilities,
and educational facilities. These
include coastal - dependent/related
institutional uses, such as the
Orange Coast College David A.
Grant Collegiate Rowing Center, the
Sea Scout Base, and the Kerckhoff
Marine Laboratory.

2.5 Tidelands and Submerged Lands
Coastal Act policies related to tidelands and submerged lands that are relevant to Newport
Beach include the following:
30213. Lower cost visitor and recreational facilities shall be protected, encouraged, and, where feasible, provided.
Developments providing public recreational opportunities are preferred.
30221. oceanfront land suitable for recreational use shaft be protected for recreational use and development unless present
and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property
is akeady adequately provided for in the area.
30223. Upland areas necessary W support coastal recreational uses shall be reserved for such uses, where feasible
2.5.1 The Tidelands Trust
Tidelands and submerged lands are
subject to a public trust that, among
other things, limits their use to
navigation, fishing, commerce, public
access, water- oriented recreation,
open space and environmental
protection. Tidelands and submerged
lands within the corporate limits of
Newport Beach are, with very limited
exceptions, owned by the State. The
vast majority of tidelands and
submerged lands in Newport Beach
have been granted to the City or the
County of Orange to administer in a
Balboa Yacht Basin manner consistent with the public
trust limitations relative to use of the property and revenue derived from that use.
The tideland boundary in Newport Harbor has been, for virtually all of the properties,
established by court judgments stemming from a series of lawsuits filed in the 1920's
and 1930's. Newport Beach tidelands also include large portions of the City's ocean
beaches and land covered by the Pacific Ocean from the shoreline three miles out to
sea and between the Santa Ana River and the east end of the Cameo Shores tract.
2.5.2 Tidelands Leases
Chapter 494 of the Statutes of 1919 granted to the City of Newport Beach all
tidelands and submerged lands that were within its corporate limits at that time.
Additional tidelands were granted by Chapter 70 of the Statutes of 1927. These
tidelands and submerged lands consist primarily of the land bayward of the bulkhead
and portions of bay beaches in the Lower Bay. The Beacon Bay Bill (Chapter 74,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -27
Statues of 1978) regranted to the City of Newport Beach all tidelands and
submerged lands that were within its corporate limits on July 25, 1919. The Beacon
Bay Bill established limitations on the use of tidelands and submerged lands to those
in which there is a general statewide purpose, including the establishment,
improvement and conduct of a public harbor, recreational facilities open to the public,
and the preservation and enhancement of the lands in their natural state. The
Beacon Bay Bill also modified some of the public trust restrictions on certain
properties, such as portions of Beacon Bay and the Balboa Bay Club, subject to a
requirement that revenue generated by these properties be used for public trust
purposes.
Beacon Bay
Beacon Bay refers to an area located
between Promontory Bay and the
Balboa Island Channel. This area
was tidelands that were filled and
reclaimed in the 1920s as the result
of an improvement plan, which
included the development of a harbor
facility that would become the Balboa
Yacht Basin. Chapter 200 of the
Statutes of 1931 allowed the area
west of the Balboa Yacht Basin
(designated as Beacon Bay) to be
leased for residential purposes. A
72 -unit residential subdivision was
developed in the 1930s, which Public beach at Beacon Bay
included 35 homes located on approximately 4 acres of State tidelands.
As indicated above, the Beacon Bay Bill released the residential lots of Beacon Bay
located within State tidelands from the public trust land use limitations and allows
existing leases to continue. These leases are limited to terms not to exceed 50
years and lease revenues have to be deposited into tidelands trust funds. Senate
Bill 573 (Chapter 317, Statutes of 1997) revised the Beacon Bay Bill to require the
residential lease revenue be deposited into specific tidelands trust funds. The current
lease runs to June 27, 2043.
In Fiscal Year 2002 -03, the City of Newport Beach received over $729,000 in lease
revenues from Beacon Bay, which were deposited in tidelands trust funds and State
Lands Commission Land Bank Fund.

Balboa Bay Club
The Balboa Bay Club and Resort is on
approximately 12.6 acres of State
tidelands held in trust by the City of
Newport Beach and leased to the
Balboa Bay Club, Inc. The property is
located on the south side of the 1200
block of West Coast Highway and was
filled and reclaimed in the 1920s as
part of a public project to develop the
Lower Bay as a harbor. The property
is currently developed with a 132 -
room resort hotel, restaurant, spa,
private club facilities, and 144 -unit
Bayfront walkway at the Balboa Bay Club and Resort apartment complex. The State Lands
Commission has determined that the
use of tidelands for private residential purposes is in conflict with the public trust
limitations on use. This conflict was first addressed in the Beacon Bay Bill (Chapter
74 of the Statutes of 1978) and later in Assembly Bill 3139 (Chapter 728, Statues of
1994). AB 3139 recognized that the lease of the apartment complex (identified as
Parcel D) for residential purposes provides fiscal and economic benefits to the public
trust and a means of improving public access. Under the provisions of AB 3139,
lease revenues are placed in tidelands trust funds to provide facilities and services
that directly support public use of tidelands and submerged lands. Income from the
apartments provides an income stream that allowed the lessee to finance the
redevelopment of the club to transition it from a private membership facility to visitor -
serving commercial land uses. AB 3139 therefore allows Parcel D to be leased for
residential purposes until no later than December 31, 2044.
In Fiscal Year 2002 -03, the City of Newport Beach received over $1,870,000 in lease
revenues from Parcel D, which were deposited in tidelands trust funds and State
Lands Commission Land Bank Fund. The redevelopment of the Balboa Bay Club
was completed in 2003 and provides public access to the hotel, restaurant, spa, the
main parking lot, and a public walkway to and along the bulkhead.

Harbor Island
Developed in 1926, Harbor Island is a 35 -lot single - family community on a private
island located between Linda Isle and Collins Island. Portions of tidelands
surrounding Harbor Island have been filled or reclaimed and are no longer
submerged or below the mean high tide line. Harbor Island residents have
improved these lands with landscaping and other improvements. The State,
through the adoption of Chapter 715, Statues of 1984, found that these lands are
generally inaccessible to the public and, in their present condition, are not suitable
for public trust uses. Both the County of Orange (most of the subject lands are
County tidelands) and City of Newport Beach are authorized to allow the Harbor
Island tidelands to be used for non - permanent recreational and landscaping uses.
These leases are limited to terms of 49 years or less and lease revenues have to be
deposited into tidelands trust funds.
Policies:
2.5.2 -1. Continue to administer the use of tidelands and submerged lands in a
manner consistent with the tidelands trust and the Beacon Bay Bill
(Chapter 74, Statues of 1978), SB 573 (Chapter 317, Statues of 1997),
AB 3139 (Chapter 728, Statues of 1994), and Chapter 715, Statues of
1984.
2.5.2 -2. Give full consideration to the public's right of access to the ocean,
beach, and bay and to the provision of coastal- dependent uses
adjacent to the water in the leasing or re- leasing of publicly owned
land.
2.5.2 -3. Give full consideration to the consistency of the proposed use with the
public trust restrictions and the public interest at the time any tideland
lease is re- negotiated or renewed.
2.5.24. Negotiate or renegotiate tidelands leases at the fair market value
based on the uses authorized in the lease and use the funds as
required by law or the public trust.
2.5.2 -5. Require public access in a manner consistent with the policies of the
Coastal Act and this LCP when the City issues new leases of public
land, or renew existing leases. This requirement shall be understood
to apply to all other public leaseholds in the coastal zone, including
beaches leased to the Lido Isle Association.

2.6 Industrial Development
Coastal Act policies related to industrial development that are relevant to Newport Beach
include the following.
30250 (b) Where feasible, new hazardous industrial development shall be located away from existing developed areas.
30260. Coastal -dependent industrial facilities shall be encouraged to locate or expand within existing sites and shall be
permitted reasonable long -term growth where consistent with this division. However, where new or expanded coastal -
dependent industrial facilities cannot feasibly be accommodated consistent with other policies of this division, they may
nonetheless be permitted in accordance with this section and Sections 30261 and 30262 if (1) alterative locations are
infeasible or more environmentally damaging; (2) to do otherwise would adversely affect the public welfare; and (3)
adverse environmental effects are mitigated to the maximum extent feasible.
30262. Oil and gas development shall be permitted in accordance with Section 30260,...
None of the City's industrial areas are
located within the coastal zone. However,
portions of Cannery Village (SP -3) are
designated for a mixture of general
commercial and light industrial uses to
encourage marine - related business.
When Newport Beach adopted its charter
in 1954, oil and gas exploration, drilling,
production, and refining was banned in the
City. However, one oil field operation
existed prior to the ban. The Newport Oil am:
Field is located in the western portion of Commercial and light industrial uses in Cannery Village
Newport Beach. The field was divided into
two areas known as the Cagney and Beach areas. The Beach Area discovery well
was drilled in 1922 and discovery well in the Cagney Area was drilled in 1947. The
Beach Area has been abandoned, but there were still 3 gas - producing wells in the
Cagney Area.
Oil and gas operations are also conducted throughout the County portion of the
Banning Ranch property (West Newport Oil Field) pursuant to California Coastal
Commission Exemption E -144. Banning Ranch is a deferred certification area due
to unresolved issues relating to land use, the future of the oil and gas operations, and
the protection of the coastal resources on the property (see Section 2.2.4).
The City of Newport Beach and other coastal communities in Southern California
have long opposed the federal government's offshore oil leasing programs. Newport
Beach residents and visitors rely heavily on the bay and oceanfront beaches for
recreation, and much of the City's economy is based upon its natural resources.
Development of offshore tracts creates visual impacts and poses the threat of
CITY COUNCIL DRAFT 1 Local Coastal Program

significant oil spills and resulting environmental damage.
Policies:
2.6-1. Coastal- dependent and
coastal - related industrial
uses shall have priority over
other industrial uses on or
near the shoreline.
2.6-2. Prohibit new onshore oil and
gas development facilities,
except as may be necessary
in conjunction with the
operation of the West
Newport Oil Field, including
the City of Newport Beach oil
facilities.
2.6-3. Prohibit the construction of West Newport Oil Field operations
onshore oil processing, refining or transportation facilities, including facilities
designed to transport oil produced from offshore tracts, with the exception of
slant drilling from onshore oil fields.
2.6-4. Continue to monitor the federal government's offshore oil leasing programs to
insure the City and its citizens are fully aware of all proposed offshore
activities, which could adversely affect the coastal environment, including
participation in the Local Government Coordination Program or other similar
programs.
2.6-5. Oppose and lobby against proposed lease sales off the coast of Orange
County and elsewhere in the Southern California region, which could
adversely affect the environment or the economy of the City of Newport
Beach.

2.7 Residential Development
Coastal Act policies related to residential development that are relevant to Newport Beach
include the following:
30007. Nothing in this division shall exempt local governments from meeting the requirements of state and federal law with
respect to providing low -and moderatemincome housing, replacement housing, relocation benefits, or any other obligation
related to housing imposed by existing law or any law hereafter enacted.
30222. The use of private lands suitable for visitor - serving commercial recreational facilities designed to enhance public
opportunities for coastal recreation shall have priority over private residential, general industrial, or general commercial
development, but not over aviculture or coastal -deoendent industry.
Newport Beach has a wide variety of residential development types in the coastal
zone, ranging from low- density single - family detached subdivisions to high - density
high -rise condominiums. Most of the residential areas in the coastal zone were
originally subdivided in the early 2& Century, with many developments marketed as
vacation home sites. This established the grid system of small lots and narrow
streets and alleys that still exists today. These subdivision characteristics and the
development of two- family and multi - family development have resulted in relatively
high residential densities in Newport Beach's coastal neighborhoods.
Coastal zone residential areas are almost completely built out, with the exception of
the Banning Ranch area (see Section 2.2.4). Most residential building activity
consists of remodeling and /or the total reconstruction of existing dwelling units.
Newport Beach's proximity to major employment markets and its desirable coastal
setting have led to steadily increasing land costs. In 2001, Newport Beach was one
of the ten California communities with the highest median home prices. This high
market demand is manifest in a number of development issues facing the City,
including development on odd - shaped or physically constrained properties, trends
towards larger dwelling units, and proposals to allow residential development in
commercial areas.
Hundreds of dwelling units in coastal zone residential areas are rented for 30 days or
less. The vast majority of these rentals occur during the summer when the demand
for parking and City services is greatest. Overcrowding and public nuisances
associated with these short-term rentals have resulted in adverse impacts to
residential areas, coastal access, and coastal resources. Since 1992, the City has
required short-term lodging permits to assist in controlling overcrowding and unruly
behavior. Short-term lodging permits require the owner of the short-term rental to
agree to limit overnight occupancy of the unit to a specific number of occupants not
exceeding that permitted by the Building Code. Short-term rental owners are also
required to use best efforts to insure that the occupants and guests are law abiding,
do not create unreasonable noise or disturbances, or engage in disorderly conduct.
Short-term rental owners are also required to use best efforts to insure compliance

with all health and sanitation regulations.
Illegal or "bootleg" dwelling units exist in
Newport Beach, experienced most often
in the older, beach - oriented areas of
West Newport, Balboa Peninsula, Balboa
Island and Corona del Mar. These units
are found in two typical forms: the
"splitting" of a single dwelling unit into two
separate occupancies, and the
conversion of garages to living space.
These units usually have a number of t
health and safety code violations, due to
conversion without proper building {�:""' ",' ""�`�•..
permits and inspections. Associated
overcrowding, traffic congestion, and west Newlwrt homes
illegal vehicle parking have also resulted in adverse impacts to residential areas and
coastal resources. Illegal dwelling units are less prevalent than in the past, due to
increased year -round owner occupancy in these areas and Report of Residential
Building Records inspections that occur when properties are sold. A Report of
Residential Building Records is a report issued by the City describing the zoning of
the residential building, the number of dwelling units permitted pursuant to the zoning
classification, and other information relevant to the use, occupancy and construction
of the residential building.
Policies:
2.7 -1. Continue to maintain appropriate setbacks and density, Floor area, and height
limits for residential development to protect the character of established
neighborhoods and to protect coastal access and coastal resources.
2.7 -2. Continue the administration of provisions of State law relative to the
demolition, conversion and construction of low and moderate - income dwelling
units within the coastal zone.
2.7 -3. Continue to authorize short-term rental of dwelling units pursuant to permits
and standard conditions that ensure the rentals will not interfere with public
access and enjoyment of coastal resources.
2.7-4. Continue to require Report of Residential Building Records inspections prior
to the sale of residential properties to reduce and prevent violations of building
and zoning codes by providing prospective owners of residential property with
information as to permitted and illegal uses and construction.

2.8 Hazards and Protective Devices
Coastal Act policies related to hazards and protective devices that are relevant to Newport
Beach Include the following:
30235. Revelments, break waters, groins, harbor channels, seawalls, cliff retaining walls, and other such construction that alters
natural shoreline processes shall be permitted when required to serve coastal -dependent uses or to protect existing structures
or public beaches in danger from erosion and when designed to eliminate or mitigate adverse impacts on local shoreline sand
supply. Existing marine structures causing water stagnation contributing to pollution problems and fishkills should be phased
out or upgraded where feasible.
30253. New development shall:
(1) "mize risks to life and property in areas of high geologic, flood, and fire hazard.
(2) Assure stability and structural integrity, and neither create nor contribute significantly to erosion, geologic instability, or
destruction of the site or surrounding area or in any way require One construction of protective devices that would substantially
alter natural landforms along bluffs and cliffs.
(3) Be consistent with requirements imposed by an air pollution control district or the State Air Resources Control Board as to
each particular development.
(4) Unirnize energy consumption and vehicle miles traveled.
(5) Where appropriate, protect special communities and neighborhoods which, because of their unique characteristics, are
popular visitor destination points for recreational uses.
30236. Channelizations, dams, or other substantial alterations of rivers and streams shall incorporate One best mitigation
measures feasible, and be limited to (1) necessary water supply projects, (2) flood control projects where no other method
for protecting edstng structures in the flood plain is feasible and where such protection is necessary for public safety or to
protect existing development, or (3) developments where the primary function is the improvement of fish and wildlife
habitat
2.8.1 General
Newport Beach is susceptible to hazards, including, storm surges, beach and bluff
erosion, landslides and slope failure, and wildland fires. Newport Beach is also
susceptible to low - probability but high -risk events like earthquakes and tsunamis. It
is the mandate of the Coastal Act to reduce potential risks to life and property and to
avoid substantial alteration of natural Iandforms. In reviewing coastal development
permits, the emphasis needs to be placed on siting and designing new development
to avoid hazardous areas rather than relying on protective devices.
Policies:
2.8.1 -1. Review all applications for new development to determine potential
threats from coastal and other hazards.
2.8.1 -2. Design and site new development to avoid hazardous areas and
minimize risks to life and property from coastal and other hazards.
2.8.1 -3. Design land divisions, including lot line adjustments, to avoid

and other hazards.
2.8.2 Tsunamis and Rogue Waves
Tsunamis
A tsunami is a sea wave caused by any large -scale disturbance of the ocean floor
that occurs in a short period of time and causes a sudden displacement of water.
Tsunamis can travel across the entire Pacific Ocean basin, or they can be local.
Large -scale tsunamis are not single waves, but rather a long train of waves. The
most frequent causes of tsunamis are shallow underwater earthquakes and
submarine landslides; however, underwater volcanic explosions, oceanic meteor
impacts, and even underwater nuclear explosions can also cause tsunamis. The
highest elevation that the water reaches as it runs up on the land is referred to as
wave runup, uprush, or inundation height. Inundation refers to the horizontal
distance that a tsunami wave penetrates inland.
The historical tsunami record for California suggests that the tsunami hazard in the
Southern Califomia region, from the Palos Verdes Peninsula south to San Diego, is
moderate. However, the Southern California historical record is very short and it is
possible that Southern California has been impacted by tsunamis for which there is
no record. More significantly, there are several active faults immediately offshore of
the Southern California area, and any of these could generate a future earthquake
that could have a tsunami associated with it. Finally, several submarine landslides
and landslide - susceptible areas have been mapped offshore, within 3.5 to 14 km (2.2
8.7 mi) to of the coastline. For the Orange County coastline particularly, near -shore
tsunamis should be considered worst -case scenarios, as these have the potential to
cause high runups that would impact the coastline with almost no warning.
The Channel Islands and Point Arguello protect Newport Beach from most distantly
generated tsunamis (teletsunamis) spawned in the Pacific Ocean, except for those
generated in the Aleutian Islands, off the coast of Chile, and possibly off the coast of
Central America. Nevertheless, since the early 1800's, more than 30 tsunamis have
been recorded in Southern California, and at least six of these caused damage in the
area, although not necessarily in Newport Beach. Tsunamis generated in the
Alaskan region take approximately 6 hours to make it to the Southern California
area, while tsunamis generated off the Chilean coast take 12 to 15 hours to reach
Southern California. Given those time frames, coastal communities in Southern
California can receive adequate warning, allowing them to implement evacuation
procedures. Alternatively, very little warning time, if any, can be expected from
locally generated tsunamis. Locally generated tsunamis caused by offshore faulting
or landsliding (including earthquake- induced landsliding) immediately offshore from
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -36
Newport Beach are possible, and these tsunamis have the potential to be worst -case
scenarios for the coastal communities in Orange County. Modeling off the Santa
Barbara coast suggests that locally generated tsunamis can cause waves between 2
and 20 m (6 to 60 feet) high, and that these could impact the coastline with almost no
warning, within minutes of the causative earthquake or slump.
The tsunami inundation maps were prepared based on several sea water levels
scenarios for 100- and 500 -year tsunamis. The findings are summarized below:
Tsunami Inundation at Mean Sea Level. In this scenario, Newport Bay and most of
the harbor would be inundated with the potential to damage small vessels and docks.
Some of the properties adjacent to the Bay would also be impacted, especially the
northwestern section of Balboa Island, which is predicted to be inundated. The water
level in Upper Newport Bay is anticipated to rise some but the data available are
insufficient to quantify the hazard in this area.
Tsunami Inundation at Mean High Water. In this scenario, Most of the harbor area,
including the inland, developed portion of the Balboa Peninsula, Balboa Island, and
Upper Newport Bay could be inundated during such an event. Near -shore sections
of Lido Isle and Linda Isle would also be impacted, and Lido Isle would be cut off
from the mainland due to Flooding along Newport Boulevard and 32nd Street. This
scenario is expected to cause considerable damage to homes in the low -lying areas
and to all moored boats.
Tsunami Inundation at Extreme High Tide. In this scenario, a significant portion of
Newport Harbor and the low -lying areas south of Coast Highway would be inundated
by both the 100- and 500 -year wave runups. The 100 -year event shows that except
for a small sliver of Lido Isle, the entire Newport Bay area would Flood. Flooding is
also anticipated in the area where Newport Dunes Resort is located. In the 500 -year
event, all of Lido Isle is expected to Flood. The probability of a tsunami occurring
during extreme high tide is highly improbable and represents the worst -case
scenario. However, these tsunami runups are possible if a tsunami occurs
immediately offshore of Newport Beach, whether as a result of faulting or landsliding.
Roque Waves
Rogue waves are very high waves, as much as tens of meters high, but compared to
tsunamis, they are very short from one crest to the next, typically less than 2 km
(1.25 mi) long. Rogue waves arise unexpectedly in the open ocean and their
generating mechanism is a source of controversy and active research. Some
theories on rogue wave formation include:
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -37
• Strong currents that interact with existing swells making the swells much
higher;
• A statistical aberration that occurs when a number of waves just happen to be
in the same place at the same time, combining to make one big wave;
• The result of a storm in the ocean where the wind causes the water surface to
be rough and choppy, creating very large waves.
Rogue waves are unpredictable and therefore making planning nearly impossible.
Nevertheless, some high waves that have historically impacted the Orange County
coastline may be best explained as rogue waves. If this is the case, rogue waves
have the potential to impact the Newport Beach area in the future.
Policies:
2.8.2 -1. Review local and distant tsunami inundation maps for Newport Beach
and adjacent coastal communities as they are developed to identify
susceptible areas and plan evacuation routes.
2.8.2 -2. Participate in any regional effort to develop and implement workable
response plans that the City's emergency services can adopt
immediately for evacuation in the case of a tsunami warning.
2.8.2 -3. Prepare and deploy a system of tsunami detection and early warning
systems.
2.8.2 -4. Include tsunami evacuation route information as part of any overall
evacuation route sign program implemented in the City. Evacuation
routes off of the peninsula and islands in the Bay should be clearly
posted. An evacuation route traffic monitoring system that provides
real -time information on the traffic Flow at critical roadways should be
considered.
2.8.2 -5. Continue projects like the Surfside- Sunset/West Newport Beach
Replenishment program to maintain beach width. Wide beaches
provide critical protection against tsunami runup for structures along
the oceanfront.
2.8.2 -6. Develop and implement a tsunami educational program for residents,
visitors, and people who work in the susceptible areas.
CITY COUNCIL DRAFT 1 Local Coastal Program

2 -38
2.8.2 -7. Encourage the Newport-Mesa School District to include in their
earthquake - preparedness curriculum information specifically related to
the natural hazards that Newport Beach's citizens could face, and what
to do about them.
2.8.2 -8. Support tsunami research in the Newport Beach offshore and Newport
Bay areas.
2.8.3 Storm Surges and Seiches
Two common coastal flooding processes include storm surges and seiches.
Storm Surges
A storm surge is an abnormal rise in
sea water level associated with
hurricanes and other storms at sea.
Surges result from strong on -shore
winds and /or intense low- pressure
cells associated with ocean storms.
Water level is controlled by wind,
atmospheric pressure, existing
astronomical tide, waves and swell,
local coastal topography and
bathymetry, and the storm's proximity
to the coast.
Most often, destruction by storm
surge Is attributable to: Storm berth at The wedge
• Wave impact and the physical shock on objects associated with the passing
of the wave front. The water may lift and carry objects to different locations.
• Direct impact of waves on fixed structures. This tends to cause most of the
damage.
• Indirect impacts, such as flooding and the undermining of major infrastructure
(such as highways and railroads).
Storm surges affect primarily ocean front property, and the low -lying areas of
Newport Bay just inland from the jetties. Newport Bay is less affected by storm
surge. Unlike tsunamis, which can occur anytime, storm surges are associated
with bad weather. Given that during bad weather fewer people are expected to be
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -39
at the beach, storm surges are more likely to impact residents than tourists, and
the potential number of casualties can be expected to be significantly less.
The most common problem associated
with storm surges is Flooding of low -lying
areas, including structures. Coastal
Flooding in Newport Beach occurred in the
+# past when major storms, many of these
r' ENSO (El Nino Southern Oscillation)
events, impacted the area. This is often
A_ 1� "". compounded by intense rainfall and
strong winds. If a storm surge occurs
during high tide, the Flooded area can be
a _ significant. In the Southern California
area, including Newport Beach, localized
Balboa Peninsula houses destroyed by storm surge firom the Flooding and accelerated rates of coastal
1939 tropical storm erosion have occurred when storms are
combined with high tides. This occurred during the 1977 -1978 storms, when the
combination of high waves, local storm surges and high tides damaged several
coastal structures in southern California. During the storms in 1988, the high water
extended to the first row of houses behind the groin field at Newport Beach causing
minor Flood damage to these structures. Storm surging associated with a tropical
storm has been reported only once in the history of Newport Beach, in 1939. This
suggests that the hazard of cyclone- induced storm surges has a low probability of
occurrence. Nevertheless, the one incident in 1939 caused millions of dollars in
damage to Newport Beach.
Seiches
A seiche is defined as a standing wave oscillation in an enclosed or semi - enclosed,
shallow to moderately shallow water body or basin, such as lake, reservoir, bay or
harbor. Seiches continue (in a pendulum fashion) after the cessation of the
originating force, which can be tidal action, wind action, or a seismic event. Seiches
are often described by the period of the waves (how quickly the waves repeat
themselves), since the period will often determine whether or not adjoining structures
will be damaged. The period of a seiche varies depending on the dimensions of the
basin. Whether an earthquake will create seiches depends upon a number of
earthquake - specific parameters, including the earthquake location (a distant
earthquake is more likely to generate a seiche than a local earthquake), the style of
fault rupture (e.g., dip -slip or strike - slip), and on the configuration (length, width and
depth) of the basin.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -40
Amplitudes of seiche waves associated with earthquake ground motion are typically
less than 0.5 m (1.6 feet high), although some have exceeded 2 m (6.6 ft). A seiche
in Hebgen Reservoir, caused by an earthquake in 1959 near Yellowstone National
Park, repeatedly overtopped the dam, causing considerable damage to the dam and
its spillway. The 1964 Alaska earthquake produced seiche waves 0.3 m (1 ft) high in
the Grand Coulee Dam reservoir, and seiches of similar magnitude in fourteen
bodies of water in the state of Washington.
Upper Newport Bay, the harbor and some of the reservoirs in Newport Beach could
be susceptible to seiches. However, there is no record of seiches impacting the area
after both local and distant earthquakes. Wind- generated seiches in Newport Bay
also have not been reported. Due to the small surface area of Newport Bay and
Upper Newport Bay, the probability that damaging seiches would develop in these
bodies of water is considered low and are not considered a significant hazard in
Newport Beach. If a seiche developed in Newport Bay, the waves are expected to
be low, impacting primarily moored boats.
Policies:
2.8.3 -1. Require all coastal development permit applications for new
development on a beach or on a coastal bluff property subject to
wave action to assess the potential for flooding or damage from
waves, storm surge, or seiches, through a wave uprush and impact
reports prepared by a licensed civil engineer with expertise in coastal
processes. The conditions that shall be considered in a wave uprush
study are: a seasonally eroded beach combined with long -term (75
years) erosion; high tide conditions, combined with long -term (75
year) projections for sea level rise; storm waves from a 100 -year
event or a storm that compares to the 1982/83 El Nino event.
2.8.3 -2. Prepare and periodically update (every 5 years) comprehensive
wave uprush and impact reports for shoreline and coastal bluff areas
subject to wave action that will be made available to applicants for
new development on a beach or coastal bluff property for use in
fulfilling the requirement of Policy 2.8.3 -1 above.
2.8.3 -3. Develop and implement shoreline management plans for shoreline
areas subject to wave hazards and erosion. Shoreline management
plans should provide for the protection of private property, public
improvements, coastal access, public opportunities for coastal
recreation, and coastal resources.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan

2.8.3 -4. Continue to utilize temporary sand dunes in shoreline areas to
protect buildings and infrastructure from wave uprush, while
minimizing significant impacts to coastal access and resources.
2.8.3 -5. Encourage the use of sand dunes with native vegetation as a
protective device in beach areas.
2.8.3 -6. Encourage the use of non - structural methods, such as dune
restoration and sand nourishment, as alternatives to shoreline
protective structures.
2.8.4 Hurricanes and Tropical Storms
Most hurricanes that affect the
southern California region are
generated in the southern portion of
the Gulf of California. Though no
hurricane - strength storms have
reportedly hit the Los Angeles basin
area in modern times, damage from
wave swell and weather related to
hurricanes that develop in the Baja
California area has been reported
throughout southern California.
Swells caused by offshore storms and
hurricanes in Baja California can

Only one tropical - strength storm has
ever been recorded as actually hitting California. Near the end of September 1939, a
tropical storm with sustained winds of 80.5 km /hr (50 mi /hr) came ashore at Long
Beach. The storm generated five inches of rain in the Los Angeles basin on
September 25th, and between 15 and 30.5 cm (6 and 12 inches) of rain in the
surrounding mountains. In Newport Beach, this storm produced 30 -foot high waves
(as high as a three -story building) that tore away half of Newport Pier and destroyed
most of Balboa Pier, damaged portions of the jetties, several homes and small
vessels, and caused numerous drownings. Other less severe but still significant
storms that impacted the southern California coastline occurred during 1927, 1938-
1939, 1941, 1969, 1977 -1978, 1983, 1988 and even more recently in 1995, and
1997 -1998. Many of these wet winters have been associated with ENSO (El Nino
Southern Oscillation) events.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -42
The main hazards associated with tropical cyclones, and especially hurricanes, are
storm surge, high winds, heavy rain, Flooding, and tornadoes. The greatest potential
for loss of life related to a hurricane for coastal communities is from the storm surge,
which if combined with normal tides can increase the mean water level by 4.6 m (15
ft) or more. Waves that high would breach or extend over the Balboa Peninsula and
impact all development adjacent to the coastline, including areas along Corona del
Mar.
2.8.5 Sea Level Rise
The level of the oceans has always Fluctuated with changes in global temperatures.
The last ice age ended approximately eighteen thousand years ago, and since then
the world has been experiencing global warming - most of the ice caps have melted,
most of the glaciers have retreated, and the sea level has risen. Until about 5,000
years ago, sea level rose rapidly at an average rate of nearly 0.4 in (1 cm) a year.
Since then, sea levels have continued to rise but at a slower pace. We are currently
in an interglacial period, meaning "between glacial" periods, and as a result, sea
levels are relatively high. However, during the last major interglacial period
(approximately 100,000 years ago), temperatures were about 1 °C (2 °F) warmer than
today and sea level was approximately 6 meters (20 feet) higher than today.
Global sea level trends, therefore, have generally been estimated by combining the
trends at tidal stations around the world. These records suggest that during the last
century, worldwide sea level has risen 10 to 25 cm (4 to 10 inches), much of which
has been attributed to global warming. Although sea level rise by itself does not
cause substantial changes in the landform, several processes associated with sea
level rise can have dramatic effects on our environment. For example, a significant
rise in sea level would inundate coastal wetlands and lowlands, and the increased
surges and swells associated with this rise in sea level would accelerate coastal
erosion and exacerbate coastal Flooding, thereby threatening local structures and
habitat. Other related processes include higher water tables, increased sea -water
intrusion into fresh water aquifers, and increased salinity of rivers, bays, and
aquifers. The warmer climate may also result in a much higher probability of
extremely warm years with increased precipitation in some areas, and drought in
other areas. It is clear that global changes in climate will occur, but the local impacts
are still being debated. In fact, recent studies have moved away from the global
doomsday predictions to predictions at the local scale. Much work yet needs to be
done in this area.
Previous studies suggest that a 1 m (39 in) rise in sea level would generally cause
beaches to erode 200 to 400 m (650 to 1,300 ft) along the California coast. Given
that the width of the beaches in Newport Beach varies between 15 and 190 m (50
and 600 ft), a sea level rise of as little as 15 cm (6 in) could have a negative impact
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -43
on the low lying areas around Newport Bay that are not protected by bulkheads and
seawalls. Sea level rise would also cause increased sea -cliff retreat in the southern
portion of the City where the beaches are narrow, and the surf pounds at the base of
the bluffs, eroding away the soft bedrock that forms the cliffs.
The record of sea level rise in the last century is poorly constrained in this region,
however. Gauge records up and down the Pacific Coast show substantial variations
in relative sea level rise. Based on the historical records from the two gauges closest
to Newport Beach, in Los Angeles and San Diego, a 15 -cm rise in sea level in the
Newport Beach area may take anywhere between 70 and 180 years, assuming that
global warming does not accelerate in the next few decades. These estimates are
too poorly constrained to engender policy changes and development of appropriate
mitigation strategies. However, sea level rise would lead to the permanent
inundation of low -lying areas, with potentially significant changes in land use, so it is
not too soon to develop longer -term strategies that can be implemented to cope with
these changes.
2.8.6 Coastal Erosion
Beach Erosion
Both natural processes and humans have modified the Newport Beach coastline
extensively for over the past 180 years. The Balboa Peninsula did not begin to form
until 1825. The wide sandy beaches that we associate with West Newport Beach
are actually the result of shoreline stabilization programs that began as early as the
1920's, and beach sand nourishment programs that began in earnest in the 1960's.
The "natural" beaches that characterized the southern California coastline prior to
significant anthropogenic intervention were narrow strips of dry beaches on a sand -
starved coast. These beaches would be unable to support the present -day demands
for coastal access and recreation.
In an undeveloped area, the availability of sand to replenish the beaches is
dependent on floodwaters that bring sediment down from the mountains and into the
littoral drift zone offshore. However, with the increase in dams and other flood
control structures upstream, significantly less quantities of sediment reach the coast.
Therefore, the sediments lost by natural near -shore processes are not being
replaced. This is certainly the case in southern California, where most of the major
streams have been dammed, or are lined in concrete, significantly reducing their
sediment load. In the Newport Beach area, sand was historically delivered to the
local beaches by the San Gabriel and Santa Ana Rivers, and to a limited extent, as a
result of coastal bluff erosion. With the construction of dams and channelization of
portions of the Santa Ana and San Gabriel Rivers, there was a substantial reduction
in the volume of sediment reaching the coastline. Construction of harbors, jetties,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -44
and other coastal barriers further reduced the amount of sand moved by along -shore
currents.
Beach sands occur from south of the
Santa Ana River to the north
entrance to Newport channel. Some
of these deposits support dune
vegetation, especially the sands
forming the Balboa and Newport
beaches. When the dune vegetation
is well established, erosion of these
sediments is minimal. However, foot
or vehicular traffic and the burrowing
action of rodents can easily
compromise the health of this
vegetation cover, exposing the near -
Beach erosion in West Newport in the late 1960s surface sediments to erosion. Sand is
easily transported during storms and
can erode quickly if up -drift sand sources are cut off.
The narrow beaches south of the channel entrance are especially vulnerable to high
waves caused by tsunamis or storm surge. Beach erosion may be a problem south
of the channel entrance due to the impedance of sediment redistribution via
longshore flow by seawalls and rocky bluffs to the north. The area north of the jetties
is also vulnerable to inundation due to low beach relief and erosion of coastal dunes
(see Section 4.1.4 for dune habitat protection).
Bluff Erosion
South of the channel entrance to Newport Bay, to the south of the beach
nourishment project area, the coastline is defined by steep coastal bluffs with a
narrow basal wavecut platform that is covered by a thin veneer of beach sand. The
bluffs form steep cliffs, especially at points. The Newport Beach coastal bluffs consist
of siliceous marine shales, marine sandstone, and siltstone of the Monterey
Formation. The sandstone beds are resistant and cliff forming, while the siltstone
beds are less resistant and form steep talus- covered slopes.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -45
The bedrock of the Monterey
Formation is folded, and dips
primarily to the east, away from the
bluff face. Overlying the Monterey
Formation are Pleistocene marine
terrace deposits. These deposits
are massive to crudely bedded,
consist of medium to coarse sand
with a trace of pebble -sized gravel,
and are friable and locally loose. A
resistant shell bed marks the base
of the terrace deposits.
At the base of the bluffs is a mantle ■" "� "�� "''��
of colluvium. It consists of angular, Erosion acoasraiansdmto increasedwaW appicaoon
pebble- to boulder -size clasts of
sandstone and siltstone. In some areas, this colluvial cover buries the bluffs almost
to the top, and in some areas, the material is reworked and forms a low terrace with
weak soil development. The colluvium is heavily vegetated and appears to protect
the base of the cliffs against normal wave action.
The elevated 100,000 -year old marine terrace deposits are prone to landslides along
steep cuts (such as those along Coast Highway) and are susceptible to significant
erosion by stream incision, including rilling and gullying along bluff tops. Several
streams are cutting through the coastal bluffs, forming steep narrow gorges and
undermining the bluffs where they emerge along the coastline. The cap of marine
terrace deposits overlying bedrock of the Monterey Formation is heavily rilled along
stream cuts and along the face of the bluffs; so it is retreating faster than the
underlying bedrock.
The shaley and silty parts of the Monterey Formation is very fissile and fractured.
Sliding and slumping of this unit appears to be the primary mechanism for current
bluff retreat, with these processes occurring primarily along slopes that have been
oversteepened by wave action (along rocky bluffs) or stream incisions.
The more sandy parts of the Monterey Formation is the most resistant bluff- forming
unit in the area. This geologic unit is prone to landsliding or mass wasting where
undercut by wave action, especially at rocky bluffs or points, failing primarily as large
blocks.
A concern with urbanization of the bluff areas is that the bluff- forming materials
become saturated when shallow ground water rises in response to the increased
watering of lawns, generally in an attempt to grow non - native vegetation. Agricultural
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -46
irrigation, septic tanks and leach lines also contribute to the increased water content
of these deposits. This over - watering increases the weight of the sediments,
lubricates any joints or fractures that can act as planes of weakness, and increases
the chemical dissolution of the underling rocks. All of these processes can contribute
to slope instability along the bluffs.
Artificial Coastal Protection
The use of artificial coastal protection
structures was favored 30 to 50 years
ago, when the groin field in West
Newport was constructed. Other
structures intended to protect the
coast, such as concrete and wooden
seawalls and bulkheads, riprap and
rock aprons are located in and around
Newport Harbor and the adjacent
shoreline. However, it has been long
observed that where such protective
structures extend seaward beyond
adjacent unprotected lots, immediate

erosion and notching may occur down drift, especially during large storms and
periods of high tide. As beach sand levels fall, storm waves tend to converge on
projecting structures (i.e. groins) and the waves refract toward unprotected areas of
the beach. Therefore given that improperly located artificial protective devices can
have negative impacts that far outweigh their benefits, beach nourishment has
emerged as the preferred method of shoreline stabilization in recent decades.
Structures built perpendicular to the shoreline tend to slow the long -shore drift of
sediments and thus starve the down -drift area of beach - nourishing sediments. This
is seen on a larger scale with the system of groins in the West Newport. The area
east of the jetties has an erosional notch due to the blockage of littoral drift from the
north. On a smaller scale, groins can have the same effect. In the case of West
Newport Beach, eight rock groins were installed in the late 1960's and early 1970's
to help maintain the beach. The effect of this groin field on the width of the beach is
readily apparent (the beach on the northwest side of the groin field is wider than the
beach where the groins are located). Southeast of the groin field, sand is being
trapped by the west jetty at the harbor entrance, which stabilizes the Balboa
Peninsula. The effect of these structures is complemented and augmented by
regular beach sand replenishment. The protection of the beaches provides more
than just a wider beach for recreational purposes and real- estate development; it
serves as a buffer zone that provides protection from tsunami runup or storm surges,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan

especially in areas where there are no dune deposits in front of residential or
commercial development.
Erosion stabilization measures that have been implemented in the Corona del Mar
area include concrete covering on one unstable slope, vegetation along the tops and
bases of bluffs, boulders at the base of bluffs, where no colluvial cover exists, and
channelization of the streams to prevent further downcutting of the terrace and
bedrock units.
Policies:
2.8.6 -1. Prepare and periodically update comprehensive studies of seasonal
and long -term shoreline change, episodic and chronic bluff retreat,
flooding, and local changes in sea levels, and other coastal hazard
conditions.
2.8.6 -2. Continue to monitor beach width and elevations and analyze
monitoring data to establish approximate thresholds for when beach
erosion or deflation will reach a point that it could expose the
backshore development to flooding or damage from storm waves.
2.8.6 -3. Develop and implement a comprehensive beach replenishment
program to assist in maintaining beach width and elevations. Analyze
monitoring data to determine nourishment priorities, and try to use
nourishment as shore protection, in lieu of more permanent hard
shoreline armoring options.
2.8.6 -4. Maintain existing groin fields and jetties and modify as necessary to
eliminate or mitigate adverse effects on shoreline processes.
2.8.6 -5. Permit revetments, breakwaters, groins, harbor channels, seawalls,
cliff retaining walls and other structures altering natural shoreline
processes or retaining walls when required to serve coastal- dependent
uses or to protect existing structures or public beaches in danger from
erosion and when designed to eliminate or mitigate adverse impacts
on local shoreline sand supply.
2.8.6 -6. Design and site protective devices to minimize impacts to coastal
resources, minimize alteration of natural shoreline processes, provide
for coastal access, minimize visual impacts, and eliminate or mitigate
adverse impacts on local shoreline sand supply.

2.8.6 -7. Discourage shoreline protective devices on public land to protect
private property /development. Site and design any such protective
devices as far landward as possible.
2.8.6 -8. Limit the use of protective devices to the minimum required to protect
existing development and prohibit their use to enlarge or expand areas
for new development or for new development. "Existing development'
for purposes of this policy shall consist only of a principle structure, e.g.
residential dwelling, required garage, or second residential unit, and
shall not include accessory or ancillary structures such as decks,
patios, pools, tennis courts, cabanas, stairs, landscaping etc.
2.8.6 -9. Require property owners to record a waiver of future shoreline
protection for new development during the economic life of the
structure (75 years) as a condition of approval of a coastal
development permit for new development on a beach or shoreline that
is subject to wave action, erosion, Flooding, landslides, or other
hazards associated with development on a beach or bluff. Shoreline
protection may be permitted to protect existing structures that were
legally constructed prior to the certification of the LCR unless a waiver
of future shoreline protection was required by a previous coastal
development permit.
2.8.6 -10. Site and design new structures to avoid the need for shoreline and
bluff protective devices during the economic life of the structure (75
years).
Note: See Section 4.4.3 for Coastal bluff policies.
2.8.7 Geologic and Seismic
Geologic
The Newport Mesa and San Joaquin Hills areas of the City include slopes that are
surficially unstable and can become a problem during intense or sustained rainfall.
Many of the geologic units underlying these areas are also easily erodible. Cuts
made into these high relief areas may be unstable if planes of weakness are
exposed. In addition to posing a hazard to life and property, landslides and slope
failure can impact traffic Flow along major routes, such as Coast Highway. Mudslides
and debris Flows also have the potential to impact development at the mouths of
canyons and at the base of the hills.
CITY COUNCIL DRAFT 1 Local Coastal Program

Compressible soils are characteristic of areas underlain by poorly consolidated
stream and colluvial deposits. These soils have a moderate to high potential for
differential settlement when a large load, such as a building, is applied to them.
Compressible soils underlie a significant part of the City. Areas of the City where
compressible soils are most likely to occur are active and recently active stream
channels, estuary deposits, beach and dune deposits, and young alluvial fan
deposits. In the San Joaquin Hills, compressible soils are commonly found in
canyon bottoms, swales, and at the base of natural slopes.
Fine - grained soils, such as silts and clays, may contain variable amounts of
expansive clay materials. These materials can undergo significant volumetric
changes as a result of changes in moisture content. The upward pressure induced
by the swelling of expansive soils can have significant harmful effects upon
structures and other surface improvements. Thick soil profiles developed on the
older marine deposits west of Newport Bay are typically clay -rich and will probably
fall in the moderately expansive range. Potentially expansive bedrock may be
exposed on natural slopes and ridges in the San Joaquin Hills, or may be uncovered
by grading cuts made for developments. Man -made fills can also be expansive,
depending on the soils used to construct them.
Seismic
The Newport- Inglewood fault extends across Newport Beach in a northwesterly
direction. The southern portion of the City is underlain by the San Joaquin Hills fault,
a recently discovered fault that does not extend to the surface but that could have
associated, secondary faults at or near the surface. A major earthquake along any
of these faults could result in substantial casualties and damage resulting in
collapsed buildings, damaged roads and bridges, fires, flooding, and other threats to
life and property.
The San Joaquin Hills blind thrust was only discovered in the late 1990s and its
geometry and behavior are not well constrained. However, an earthquake on this
fault, due to its blind thrust geometry and location has the potential to be more
damaging to Newport Beach than rupture of the Newport- Inglewood fault. Typically,
earthquakes on thrust faults produce greater vertical accelerations than comparably
sized strike -slip earthquakes (such as one on the Newport- Inglewood fault) and
vertical motions are more damaging to structures. Scientists suggest the San
Joaquin Hills blind thrust fault could produce a magnitude 6.8 to 7.3 earthquake.

The Newport- Inglewood fault is considered the
second most active fault in California. Prior to the
discovery of the San Joaquin Hills fault, the
Newport- Inglewood fault was thought to pose the
greatest threat to Newport Beach because of its
close proximity to the City, historic activity, and its
recurrence interval. It runs from the City of
Inglewood through Newport Beach where it extends
out into the Pacific Ocean. This fault is capable of
producing earthquakes in the range of 6.3 to 7.5
magnitudes. The 1933, 6.5 magnitude Long Beach
earthquake occurred on the Newport- Inglewood
fault, causing 120 deaths and severe damage.
Unreinforced masonry buildings collapsed leaving
people trapped beneath the rubble. Schools
collapsed. The Long Beach earthquake epicenter
was in the Newport Harbor area of Newport Beach.
Buildings were damaged in the City as a result of
this earthquake. The low population and
development of the time attributed to decreased
damage in the Newport Beach area. Damage to home and Park Avenue on
g Balboa Island caused by the 1933 Long
Beach earthquake
The San Andreas fault is located approximately 70 miles northeast of the City. This
fault is capable of producing earthquakes in the magnitude 8+ range. Current
estimates are that major earthquakes on this fault occur approximately every 145
years. The last major earthquake on the Southern San Andreas fault occurred in
1857.
The Whittier fault is the northern extension of the Elsinore fault and is located
approximately 20 miles north of the City. No major historical earthquakes have been
attributed to the Whittier fault. However, trenching studies have documented
recurrent movement of this fault in the last 17,000 years. The Southern California
Earthquake Center determined there is a five percent chance of an earthquake
occurring on the Whittier fault by 2024. The Whittier fault is thought capable of
producing a magnitude 6.8 maximum magnitude earthquake, although some
investigators propose an even larger magnitude 7.1 quake.
In addition to the four fault systems mentioned above, there are several other known
potential sources of strong ground shaking within 60 miles of Newport Beach. These
include the Peralta Hills, Santa Monica - Hollywood, Puente Hills and Cucamonga
faults. These faults could also affect Newport Beach, though not as severely. There
are still many uncharted earthquake faults throughout California and several active
offshore faults posing possible impacts for Newport Beach.

Poorly consolidated sediments and shallow groundwater underlie portions of
Newport Beach, particularly from West Newport to the tip of the Balboa Peninsula
and in the areas in and around Newport Bay. These areas have a high susceptibility
to liquefaction during earthquakes. Liquefaction is a geologic process that causes
various types of ground failure. When liquefaction occurs, the sediments involved
have a total or substantial loss of shear strength, and behave like a liquid or semi -
viscous substance. Liquefaction can cause structural distress or failure due to
ground settlement, a loss of bearing capacity in the foundation soils, and the buoyant
rise of buried structures. The excess of hydrostatic pressure generated by ground
shaking can result in the formation of sand boils or mud spouts, and /or seepage of
water through cracks.
The areas with the liquefaction potential are densely populated and possess
considerable commercial property. It is likely that a nearby moderate to strong
earthquake will cause extensive damage to buildings and infrastructure. Newport
Beach requires the properties in these areas to be built on compacted soils, which
should lessen the liquefaction potential.
Other secondary affects of earthquakes include:
■ Fires. A high probability of fire following an earthquake results from the
number of broken gas lines typically occurring during shaking. Water mains
and lines often break as well, due to ground movement. The combination of
fires and a water shortage seriously complicates the response to earthquakes
and their secondary affects.
• Dam Failure. Flooding caused by earthquake induced dam failure of the
Prado Dam could impact Newport Beach. However, the probability of
Flooding due to dam failure is low since the Prado Dam is rarely full. Flooding
could also result from the failure of the Big Canyon Reservoir.
■ Hazardous Chemical Spills. The north end and west side of the Newport
Beach house a large percentage of the City's industries with large quantities
of hazardous chemicals. This area would be most affected by hazardous
chemical spills and hazardous chemical fires resulting from earthquakes.
■ Oil Spills and Pipeline Breakage. Oil fields and oil storage tanks can be seen
on the west side of Newport Beach. Although the tanks are diked, a major
earthquake could damage the tanks and dikes causing vast amounts of oil
spillage. There are numerous underground pipelines traversing the City. An
earthquake could easily cause a pipeline breakage, releasing either natural
crude oil or refined petroleum products.

order to minimize hazards resulting from increased runoff, erosion and
other hydrologic impacts to streams.
2.8.7 -3. Require applications for new development, where applicable [i.e., in
areas of known or potential geologic or seismic hazards], to include a
geologic /soils /geotechnical study that identifies any geologic hazards
affecting the proposed project site, any necessary mitigation
measures, and contains a statement that the project site is suitable for

2.8.8 Fire
1993 Laguna Canyon fire advancing towards Newport Beach
Due to its weather, topography and
native vegetation, the entire southern
California area is at risk from wildland
fires. The extended droughts
characteristic of California's
Mediterranean climate result in large
areas of dry vegetation that provide
fuel for wildland fires. Furthermore,
the native vegetation typically has a
high oil content that makes it highly
flammable. The area is also
intermittently impacted by Santa Ana
winds; the hot, dry winds that blow
across southern California in the
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -53
spring and late fall, often igniting and /or spreading fires. Combine these conditions
with the fact that more people than ever are living and playing in wildland areas, and
the potential for major wildland fires to occur increases even further.
Fires usually last only a few hours or days, but their effects can last much longer. An
intense wildland fire may destroy all the vegetation. The fire also destroys most of
the roots that hold the soil in place, allowing running water to wash the soil away. In
addition, the organic material in the soil may be burned away or decompose into
water - repellent substances that prevent water from percolating into the soil. As a
result, even normal rainfall can cause exceptional erosion, Flooding and debris Flows
from a burned area. The 1993 Laguna Canyon wildland fire burned 17,000 acres,
destroyed 366 homes, and forced the evacuation of Laguna Beach's 24,000
residents. In 1997, wildland fires charred many areas of southern California, leaving
them barren before the next winters heavy El Nino rainfall. Of the 25 large southern
California wildland fires that occurred that year, ten produced debris Flows after the
first major winter storm, and Flooding plagued eight other areas. Only four burn areas
showed little erosion or runoff.
Flood control facilities may be severely taxed by the increased Flow from the
denuded hillsides and the resulting debris that washes down. Recreation areas that
have been affected may also be forced to close or operate at a reduced scale. In
addition, the buildings that are destroyed by fire are usually eligible for
reassessment, which reduces income to local governments from property taxes.
In the aftermath of the 1993 Laguna
Canyon fire, Newport Beach fire
officials, in cooperation with federal,
state, county, and other local officials,
began analyzing the conditions that
allowed this fire and others to occur.
The areas at greatest risk of wildland
fires are homes and structures in and
around the urban wildland interface
areas. These areas include lower Buck
Gully, Morning Canyon, the mouth of
Big Canyon, and Spyglass Canyon.
Newport Beach employs two different Homes adjaceot to Buck GNly
methods for reducing the risk of fire in
these urban wildland interface areas: hazard reduction and fuel modification. Both
methodologies use the principle of reducing the amount of combustible fuel
available, which reduces the amount of heat, associated Flame lengths, and the
intensity of the fire that would threaten the adjoining structures. Hazard reduction
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -54
reduces the amount of fuel within 100 feet of any structure, thus creating a
defensible space used to slow the rate and intensity of an advancing wildfire and to
create an area for firefighters to suppress the fire and save the structure. Fuel
modification zone establishes a ribbon of land surrounding the homes designed to
diminish the intensity of a wildfire as it approaches the homes. A fuel modification
zone differs from a hazard reduction zone through a combination of methodologies,
including the removal of native vegetation replaced with fire resistive plant species,
as well as the reduction of amount of native combustible vegetation.
In addition to reduction of the vegetation hazards, areas regulated by fuel
modification requirements are also required to "harden" the structures immediately
adjacent to the wildland area. This "hardening" is done by providing automatic fire
sprinkler protection, installation of class "A" roof assemblies, installation of dual
glazed windows, one -hour fire resistive construction on sides of the structure facing
the wildland area, and the elimination of any combustible exterior structural
elements, such as patio covers.
Policies:
2.8.8 -1. Apply hazard reduction, fuel modification, and other methods to reduce
wildfire hazards to existing and new development in urban wildland
interface areas.
2.8.8 -2. Site and design new development to avoid the need to extend fuel
modification zones into sensitive habitats.
2.8.8 -3. Use fire- resistive, native plant species from the City- approved plant list
in fuel modification zones abutting sensitive habitats.
2.8.8 -4. Prohibit invasive ornamental plant species in fuel modification zones
abutting sensitive habitats.
2.8.8 -5. Continue to maintain a database of parcels in urban wildland interface
areas.
2.8.8 -6. Continue annual inspections of parcels in the urban wildland interface
areas and, if necessary, direct the property owner to bring the property
into compliance with fire inspection standards.
2.8.8 -7. Continue to regularly update building and fire codes to reflect the best
available standards for fire safety design.

following:
302125. Wherever appropriate and feasible, public facilities, including parking areas or facilities, shall be distributed
throughout an area so as to mitigate against the impacts, social and otherwise, of overcrowding or overuse by the public of
any single area.
30252. The location and amount of new development should maintain and enhance public access to the coast by (1)
facilitating the provision or extension of transit service, (2) providing commercial facilities within or adjoining residential
development or in other areas that will minurize the use of coastal access roads, (3) providing nonautomobile circulation
within the development, (4) providing adequate parking facilities or providing substitute means of serving the development
with public transportation, (5) assuring the potential for public transit for high intensity uses such as high-rise office buildings,
and by (6) assuring that the recreational needs of new residents will not overload nearby coastal recreation areas by
correlating the amount of development with local park acquisition and development plants with the provision of onsite
recreational facilities to serve the new development
2.9.1 Public Transit
The City's Transportation Demand Management Ordinance requires new
nonresidential developments that are estimated to employ 100 or more employees to
reduce the number of peak - period vehicle trips, promote and encourage the use of
alternative modes of transportation, and provide support facilities for alternative
modes of transportation.
Bus Transportation
Public transportation services in Newport
Beach are provided by the Orange County
Transportation Authority District (OCTA) and
consist of regular fixed -route service. OCTA
operates the Newport Beach Transportation
Center at Avocado and San Joaquin Hills
Road. Demand for bus service from the inland
areas to Newport Beach is intensified during
the summer peak months. OCTA adds buses
to beach routes most in demand to offset the
increased load.
The City's Subdivision Code provides for the
dedication of transit facilities, such as bus
turnouts, benches, shelters and similar
facilities, by new development. The City's
Public Works Department coordinates with
OCTA on the location of transit facilities.

2.9.3 Parking
Parking in the coastal zone is a major issue in Newport Beach. Surveys indicate that
the current supply is generally adequate in the winter for both residents and visitors.
During the summer the demand for parking increases. During peak summer
weekends, parking demand associated with beach and bay uses is virtually
unlimited.
Commercial
All of the commercial areas in the coastal zone were originally developed at a time
when little or no off -street parking was required. Therefore, a number of properties
do not conform to current off -street parking requirements. In many coastal zone
commercial areas, commercial parking demand is accommodated by on -street
parking spaces and in public lots. This has created conflicts between commercial
uses, residential uses, and coastal zone visitors.
The City's off -street parking regulations are consistent with other coastal
communities and are adequate to meet land use demands. Therefore, new
development will be required to provide adequate off -street parking.
The coastal zone's main commercial areas were studied during the summer of 2002
to determine if there is adequate parking. Field observations and analysis were
conducted to inventory and review current parking conditions. A forecast of future
parking adequacy was also conducted using a parking analysis model.
West Newport commercial
K
West Newport. West Newport is a
commercial strip on the north side of
West Coast Highway between the
Semeniuk Slough and the city limits.
Of the 258 parking spaces, there are
slightly more private off -street spaces
(57 %) than public on -street spaces.
There are also 174 public spaces on
the south side of West Coast Highway
in the West Newport Park lots and on
Seashore Drive. The 2002 field
observations indicate there is
adequate parking on the north side of
West Coast Highway to meet land use
demands. Public spaces along the
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -59
south side were occupied with residential vehicles in the early morning and were
replaced with beach traffic in the afternoon until the evening when residential
vehicles returned.
The parking analysis model indicates that parking in this area should be adequate to
accommodate demand. Beach users mainly use the parking on the south side and it
is anticipated that none of these spaces are needed to serve demand from the north
side of the highway.
Mariner's Mile. The Mariner's Mile commercial area is located on Coast Highway
between Newport Boulevard and Dover Drive. Marine - related, visitor serving, and
entertainment businesses dominate the Mariner's Mile waterfront. Therefore, most
coastal zone visitors in this area are patrons of these businesses. The vast majority
(87 %) of 3,245 parking spaces in Mariner's Mile are private spaces designated for
use by business patrons. The 2002 field observations indicate there is adequate
parking during daytime hours, but that parking facilities reach effective capacity
during evening hours, due to the concentration of restaurants and entertainment
establishments.
The parking analysis model indicates that a parking shortage should be experienced
in the Mariner's Mile area during the weekday midday hours. This discrepancy with
the 2002 field observations indicate that the area is experiencing a higher than
normal amount of multi- purpose trips, and /or trips by alternative mode than
estimated in the parking requirements or that some land uses may not be open
during the weekday midday hours as anticipated in the parking estimates.
Balboa Peninsula. Lido /McFadden includes the
Lido, Civic Center, Cannery Village, and Newport
Pier commercial areas. The majority (56 %) of
5,393 parking spaces in Lido /McFadden are in
public lots and on- street. In Balboa Village, the vast
majority (73 %) of 1,267 parking spaces are in public
lots and on- street. The 2002 field observations
indicate that on both weekdays and weekends,
public lots are used more heavily than any other
type of parking and private lots have the lowest
occupancy. Parking analysis indicates parking
shortfalls in both Lido/McFadden and Balboa
Village.
Balboa Pier parking lot

Marine Avenue. Marine Avenue is a
retail district on Balboa Island that is
popular with residents and coastal
zone visitors. Of the 134 parking
spaces, there are slightly more public
on -street spaces (57 %) than private
off -street spaces. The 2002 field
observations indicate that parking is
routinely at or above capacity and that
parking demand extends well beyond
the blocks immediately surrounding
the business area.
Marine Avenue on Balboa Island The model indicates a significant latent
demand for parking in this area. The
density of development along Marine Avenue and the pedestrian- oriented character
of the development create a unique condition in this area. Land uses in the area
generate trips with a much higher than normal amount of multi - purpose stops. In
addition, many of the existing land uses cater to the needs of the local residents who
walk to and from the sites, as well as to visitors. Therefore, the actual parking
demand is less than the model is predicting. However, the demand is still much
higher than the current supply.
Corona del Mar. Corona del Mar is a commercial strip along East Coast Highway
between Avocado Avenue and Hazel Drive. Only the south side of this commercial
area is located within the coastal zone. The vast majority (88 %) of 2,031 parking
spaces in Corona del Mar are private spaces designated for use by business
patrons. The 2002 field observations indicate there is adequate parking to meet land
use demands.
The parking analysis model indicates that existing supply is more than adequate for
the existing uses. Overestimated demand may be caused by a higher than expected
number of multi - purpose trips or differences in the anticipated split of modes of
transportation. Because of the amount of private parking in this area versus public
spaces, it is less likely to have a large amount of shared parking occurring because
of temporal differences in parking demand.
Residential
Most of the residential areas in the coastal zone were also developed at a time when
there was little need for automobile parking. However, unlike commercial areas, high
market demand has resulted in continual remodeling and reconstruction of
residential properties. New dwelling units and remodels resulting in an increase in
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
2 -61
the number of habitable rooms are required to meet current off -street parking
requirements.
Street pxkig on the Balboa Pemstla
Policies:
While remodels and reconstruction have increased
the amount of off -street parking, parking problems
continue in coastal zone residential areas.
Residential dwelling units with nonconforming
parking continue to exist. Also, some garages are
used for purposes other then parking, including
storage, office space, or living areas. The
popularity and demographics of the coastal zone
sometimes leads to dwelling units with more people
and automobiles than in inland areas. Illegal
dwelling units also add to parking demand. Finally,
some people simply prefer to use curbside parking
due for convenience, particularly in areas where
garages are accessed via narrow alleys. As a
result, a significant number of coastal zone
residents use public street parking or public lots
instead of private off -street parking.
2.9.3 -1. Site and design new development to avoid use of parking
configurations or parking management programs that are difficult to
maintain and enforce.
2.9.3 -2. Continue to require new development to provide off -street parking
sufficient to serve the approved use in order to minimize impacts to
public on -street and off -street parking available for coastal access.
2.9.3 -3. Continue to require off -street parking in new development to have
adequate dimensions, clearances, and access to insure their use.
2.9.3 -4. Continue to require properties with nonconforming parking to provide

• Provides adequate, convenient parking for residents, guests,
business patrons, and visitors of the coastal zone;
• Optimizes use of existing parking spaces;
• Provides for existing and future land uses;
• Reduces traffic congestion;
■ Limits adverse parking impacts on user groups;
■ Provides improved parking information and signage;
■ Generates reasonable revenues to cover City costs;
■ Accommodates public transit and alternative modes of
transportation.

3.1.1 Shoreline Access
In terms of implementing the Coastal Act, there are two basic types of public access:
vertical access, or access to the shoreline, and lateral access, or access along the
shoreline. Newport Beach has developed an extensive system of access to ocean
beaches and the bay (see Coastal Access Map). Virtually all of the Pacific Ocean
shoreline beaches are public and the bay is accessible via public beaches, parks,
shoreline trails, walkways and boardwalks. The City will continue to require all new
development, causing or contributing to adverse public access impacts, to provide
easements or dedications in areas where public access is inadequate.

Pacific Ocean Beaches
West Newport/Balboa Peninsula. West
Newport and the Balboa Peninsula
have over 5 miles of wide, sandy
beaches. Vertical access to these
beaches is provided by 89 street ends,
which occur every 200 to 500 feet. The
Oceanfront Boardwalk runs along the
beach for approximately 3 miles from

Lower Newport Bav /Harbor
West Newport/Balboa Peninsula. The
Lower Bay shoreline of West Newport
and the Balboa Peninsula consist of
relatively narrow sandy beaches and
bulkheads. There are 89 street ends
that provide vertical access to Lower
Newport Bay, including The Rhine,
Newport Island, Rialto, and Rivo Alto
channels. Most street ends provide a
small beach and shore moorings.
Larger public beaches are located at
Las Arenas Beach (16°i -19°' Street),
10" Street Beach, MonterO Beach
Las Arenas Beach (Island Avenue to Medina Way), and N
Street Beach. Small public beaches
are also located at Channel Place Park and Newport Island Park. There is also a
0.65 -mile bayfront walkway that extends from Main Street in Balboa Village to 7"'
Street.
Waterfront commercial areas also provide
vertical and lateral access to Lower Newport
Bay. Commercial developments in Lido Village,
Cannery Village, McFadden Square, and
Balboa Village and on the Lido Peninsula
provide public access easements to and along
the waterfront. In most cases, these easements
have been integrated into the project's design,
such as restaurants with outdoor waterfront
dining areas and boarding areas for charter and
excursion vessels.
New development will present additional
opportunities to extend and enhance waterfront
access in these areas. Particular attention
should be given to extending the Lido Marina
Village boardwalk across all of the waterfront
commercial properties in Lido Village and to
provide a continuous waterfront walkway along
the Rhine Channel to connect the Cannery Lido Manna Village doardwark
Village and McFadden Square waterfront commercial areas with Las Arenas Beach
at 19°i Street. A connection from Lido Village to Mariner's Mile should also be
provided, if feasible.

Mariner's Mile. The Mariner's Mile is a
commercial area with a shoreline
consisting of bulkheads. Commercial
and institutional developments in
Mariner's Mile provide public access
easements to and along the waterfront.
Although the easements are
fragmented, with new development,
there is an opportunity to provide a
continuous waterfront walkway from the
Coast Highway /Newport Boulevard
Bridge to the Balboa Bay Club.
Bayside. The Bayside area shoreline Mariners Mile
consists mainly of bulkheads, with a few small beaches. Beacon Bay Beach (Lot 1) is
accessible from Beacon Bay Drive via walkways at the Cape Cove, Shelter Cove,
and Reef Cove Street ends. Bayside Drive County Beach is accessible from
Bayside Drive via the Orange County Harbor Patrol facility. Lateral access to
Promontory Bay is provided by a walkway along Bayside Drive and a public access
easement along the bulkhead adjacent to Newport Manna Apartments. This public
access easement connects to a quarter mile walkway on a floating dock in the
Balboa Island Channel. Lateral access is also provided around the Balboa Yacht
Basin.
Corona del Mar. Corona del Mar's bayside
shoreline is at the harbor entrance and is
characterized by high coastal bluffs with a few
small sandy coves. China Cove is accessible from
Cove Street and Shell Street. Rocky Point (Pirate's
Cove) is accessible by a trail at Lookout Point on
Ocean Boulevard and Corona del Mar State
Beach. There is also a small pocket park in an
unnamed street end off of the 2300 block of
Bayside Drive that provides access to Carnation
Cove.
Lido Isle. On Lido Isle, vertical access to the Lower
Bay is provided by walkways within 13 street end
easements. These street ends are leased to Lido
Isle Association with the condition that the
association maintain and operate all walkways in a
manner that allows for open public access. There are also public beaches at Via
Pirate's Cove Genoa (Parcel B) and at Via Trieste (Parcel C).

Balboa Island. All of Balboa Island's beaches are public. There are 33 street ends
that provide vertical access and the Bay Front Boardwalk that circles the island
enhances lateral access. There are also 4 street ends that provide access to the
Grand Canal.
Upper Newport Bay
The Upper Newport Bay is coastal
wetlands bordered by 40 to 100 -foot high
bluffs. Most of the Upper Newport Bay
area is in the Upper Newport Bay Marine
Park. Due to the steep coastal bluffs and
high number of sensitive environmental
resources within the marine park, access
is more restricted than other coastal
areas. Still, ample public access is
available.
The 752 -acre Upper Newport Bay Marine
Park preserves one of the largest coastal upper Newport Bay Marine Park
wetlands in Southern California. In
addition to protecting its diverse habitats, the marine park provides canoe, kayak,
and walking tours. Shellmaker Island in the marine park serves as a staging area
for tours of the Upper Newport Bay. Shellmaker Island is only open to the public
when programs and tours are scheduled and is accessible from Back Bay Drive.
The marine park is also accessible from University Drive and Back Bay Drive.
The Upper Newport Bay Nature Preserve is
located on the bluffs on the north and northwest
sides of the Upper Newport Bay Marine Park.
This 140 -acre regional park provides hiking, bike,
equestrian trails to and along the marine park.
The Upper Newport Bay Nature Preserve is
accessible from University Drive and Bayview
Way.
Access to and along the Upper Newport Bay is
also provided by Back Bay Drive, a 3.5 -mile multi -
model road that runs along the base of the bluff on
the easterly side of the bay. Back Bay Drive
begins at Jamboree Road and ends at East Bluff
Drive, where it connects with a trail that continues
west of Jamboree Road and along San Diego
Creek into central Orange County. The Lookout at
Bads Bay Drive

the corner of Back Bay Drive and East Bluff Drive serves as a staging area for tours
of the bay.
On the west side of the bay, access is provided via North Star Beach. North Star
Beach has a sandy beach and is the site of the Newport Aquatics Center, a public
recreation and launching facility. North Star Beach is accessible from White Cliffs
Drive, off of Polaris Drive. The area north of the Newport Aquatics Center contains
natural habitats and the provision of additional public access in this area must be
consistent with the protection of these resources.
On the east side of the bay, access is provided by Big Canyon Nature Park. Big
Canyon Nature Park is a passive open space area that provides hiking trails from
Jamboree Road to the Upper Newport Bay Marine Park. The mouth of Big Canyon
contains natural habitats and the provision of additional public access must be
consistent with the protection of these resources.
Semeniuk Slouch
Semeniuk Slough, also referred to as the Oxbow Loop, is a coastal salt marsh. The
slough is accessible via 9 street ends in Newport Shores and the Newport Shores

3.1.3 Beach Encroachments
On June 11, 1991, the Coastal
Commission approved the Oceanfront
Encroachment Policy (Amendment No.
23), which established a policy and
mitigation program relating to private
improvements within the Oceanfront .. _
public right -of -way. The City Council
finalized this policy with the adoption of _
Resolution No. 91 -80 on July 11, 1991.
This policy established conditions and
restrictions on the nature and extent of
these improvements and a mitigation
program involving the reconstruction of West Newport street end
33 unimproved street ends between 36th
Street and Summit Street to provide additional parking and improved public access.
In 2002, the final five street ends were reconstructed. Pursuant to the mitigation
program, a minimum of 85 percent of the encroachment fees will be used for the
construction and maintenance of improvements which directly benefit the beach -
going public such as parking spaces, restrooms, vertical or lateral walkways along
the beach and similar projects.
Policies:
3.1.3 -1. Continue to maintain and improve the Oceanfront public right -of -way for
public access purposes.
3.1.3 -2. Continue to restrict the nature and extent of improvements that may be
installed over public rights of way on the oceanside of beachfront
residences and to preserve the City's right to utilize oceanfront street
easements for public projects.
3.1.3 -3. Limit the maximum oceanward extent of encroachments to the following
encroachment zones:
A. Santa Ana River to 52nd Street. A maximum of 15 feet oceanward of
the rear (ocean facing) property line within the oceanward prolongation
of the side property lines.

3.1.4 Bay /Harbor Encroachments
Shore connected structures, such as
piers, Floats, and bulkheads have long
been permitted in the bay and harbor.
Newport Beach, in conjunction with
Federal, State, and County agencies, has
established a set of Harbor Lines to
define bayward limits for various types of
structures. Harbor Lines and other
regulations were originally established to
insure navigable channels and safe
harbor operations and to minimize
conflicts with adjacent properties.
However, such regulations are
increasingly used as a means of
protecting public views and public access.
Policies:
Resider ial piers
3.1.4 -1. Continue to regulate the construction of bay and harbor structures
within established Bulkhead Lines, Pierhead Lines, and Project Lines.
3.1.4 -2. When applicable, continue to require evidence of approval from the
County of Orange, Coastal Commission, U.S. Army Corps of
Engineers, and other resource management agencies, prior to issuing
permits.
3.1.4 -3. Design and site piers, including remodels of and additions to existing
piers so as not to obstruct public lateral access and to minimize
impacts to coastal views and coastal resources.
3.1.4 -4. In residential areas, limit structures bayward of the bulkhead line to
piers and floats. Limit appurtenances and storage areas to those
related to vessel launching and berthing.
3.1.4 -5. Encourage the joint ownership of piers at the prolongation of common
lot lines as a means of reducing the number of piers along the
shoreline.
3.1.4 -6. Continue to prohibit private piers at street ends.
3.1.4 -7. Design and site bulkheads to protect the character of the existing
shoreline profiles and avoid encroachment onto public tidelands.

3.1.5 Private /Gated Communities
Throughout Southern California, access to the shoreline is restricted to the public
due to private residential communities. Exclusive gated communities in some cases
totally circumvent public access to the shoreline. Such communities present a major
issue in terms of protecting, expanding, and enhancing coastal access.
Most of the shoreline in Newport Beach is publicly owned and accessible. However,
there are a few private residential communities that impede public access to and
along the shoreline. These communities are Balboa Coves, Bay Island, Bayshores,
Bayside Place, Collins Island, De Anza Bayside Village, Linda Isle, and Harbor
Island. Some of these communities are on small private islands. They do not impede
access to public beaches, coastal parks, trails, or coastal bluffs; however, they do
block public access to and along their immediate shoreline. Balboa Coves, Bayside
Place, Bayshores and De Anza Bayside Village are on the mainland, but are situated
so as not to block public access other than to their immediate shoreline. In all of
these areas, the shoreline consists mainly of bulkheads with a few small and isolated
sandy beaches.
Balboa Coves. Balboa Coves is a 68 -lot single - family gated community located on
the Newport Island Channel southwest of the Newport Boulevard /Coast Highway
Bridge. The community is accessible from Coast Highway via Balboa Coves, a
private street. The shoreline is on the south side of the community and consists of a
series of manmade coves with narrow sandy beaches.
Bay Island. First developed around
1904, Bay Island is a 25 -unit
(currently developed with 24 units,
including one caretaker's unit) single
family cooperative on a private
island in the Newport Channel. A
gated pedestrian bridge at the end of
Island Avenue connects Bay Island
with the Balboa Peninsula. Motor
vehicles are prohibited on the island.
Off -street parking for residents is
provided at a 48 -space parking
structure located at 501 West Bay
Bay Island Avenue. The shoreline consists
mainly of bulkheads, with the exception of the east side of the island, which has a
relatively wide sandy beach.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
3 -17
Bayshores. Developed in 1941, Bayshores is a 258 -lot single - family gated
community located on the Lido Channel southwest of the Coast Highway /Newport
Bay Bridge. The 39 -unit Anchorage Apartments is also located within the
community. The community is accessible from Coast Highway via Bay Shores
Drive, a private street. The shoreline is on the south and east sides of the
community and consists of bulkheads and two small sandy beaches.
Bayside Place. Bayside Place is a 7 -lot single - family gated community located off of
the 2300 block of Bayside Drive. The community is accessible from Bayside Drive
via Bayside Place, a private street. The shoreline (Carnation Cove) consists of
bulkheads and rocky beaches. Public access to the shoreline is available at an
adjacent street end pocket park.
Collins Island. Created in 1906, Collins Island is a 7 -lot single - family community on a
private island in the Balboa Island Channel. A gated bridge at the end of Park
Avenue connects Collins Island with Balboa Island. The shoreline consists of
bulkheads.
De Anza Bayside Village. De Anza Bayside Village is a 343 -space mobile home
park located on the Upper Newport Bay adjacent to the Newport Dunes. The
community is accessible to Bayside Drive via Bayside Way, a private street. The
shoreline is on the north side of the community and consists of bulkheads and a
small sandy beach at the community center. The community includes the
undeveloped De Anza / Bayside Marsh Peninsula.
Harbor Island. Developed in 1926,
Harbor Island is a 35 -lot single -
family community on a private
island located between Linda Isle
and Collins Island. A gated bridge
connects Harbor Island to the
mainland at the end of Harbor
Island Road. The shoreline
consists mainly of bulkheads. The
State, through the adoption of
Chapter 715, Statues of 1984,
found that tidelands surrounding
Harbor Island are generally
inaccessible to the public and not
suitable for public trust uses (see
Section 2.5.2).
Harbor Island
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
3 -18
Linda Isle. Created in 1933 and developed in the 1960s, Linda Isle is a 107 -lot
single - family community on a private island southwest of the Coast Highway Bridge.
A gated bridge connects Linda Isle to the mainland at Bayside Drive. The shoreline
consists of bulkheads and a small sandy beach.
All of these communities are long established. New development is generally of a
type and scale that does not have a direct adverse impact on existing public access.
Such new development generally consists of additions or demolition and subsequent
reconstruction of existing structures. Requiring public access under such
circumstances would not present a reasonable relationship between the exaction
and a project and would be disproportionate to the impact. However, new
development resulting in significant increases in land use density or intensity would
have the potential to have a direct adverse impact on public access. Similarly, new
development that limits or eliminates private recreational facilities within such
communities could place additional demand on public recreational facilities, including
beaches. Under such circumstances, public access mitigation in a manner
consistent with the public access policies of the Coastal Land Use Plan would be
required.
Policies:
3.1.5 -1. Prohibit new development that incorporate gates, guardhouses, barriers or
other structures designed to regulate or restrict access where they
would inhibit public access to and along the shoreline and to beaches,
coastal parks, trails, or coastal bluffs when there is substantial evidence
that prescriptive rights exist.
3.1.5 -2. Prohibit new private streets, or the conversion of public streets to private
streets, where such a conversion would inhibit public access to and along
the shoreline and to beaches, coastal parks, trails, or coastal bluffs when
there is substantial evidence that prescriptive rights exist.
3.1.5 -3. Require public access consistent with public access policies for any new
development in private /gated communities causing or contributing to
adverse public access impacts.

3.1.6 Preferential Parking Districts
Newport Island
In Newport Beach, there is only one
preferential parking district in the
coastal zone. It was established for
Newport Island in 1981 due to
impacts associated with vehicle
parking on streets and alleys by
nonresidents for extended periods of
time. The establishment of the
Newport Island preferential parking
district was determined not to
adversely impact coastal access
and recreation due to the island's
isolated location, lack of beaches
and swimming areas, and narrow
streets.
The establishment of additional preferential parking districts may be necessary
where no other practical or feasible alternative exists to protect the public health,
safety, and general welfare. Under such circumstances, if there is a direct impact to
coastal access or recreation, preferential permit parking fees could be established to
fund mitigation programs.
Policies:
3.1.6 -1. Prohibit the establishment of new preferential parking districts in the
coastal zone except in areas where such restrictions would not have a
direct impact to coastal access, including the ability to use public
parking, or where no other practical or feasible alternative exists to
protect the public health, safety or general welfare.
3.1.6 -2. Require a coastal development permit to establish new, or modify
existing, preferential parking districts.
3.1.6 -3. Use preferential parking permit fees to fund programs to mitigate
impacts to coastal access.
3.1.6 -4. Where appropriate, establish a graduated preferential parking permit
fee schedule where progressively higher fees are required for each
permit for households with multiple permits.
3.1.6 -5. Limit the number of preferential parking permits issued per household.

3.1.7 Temporary Events
2e Street Beach
Newport Beach's coastal areas have
long been the venue for temporary
events, including film production,
surfing contests, volleyball
tournaments, runs, races, concerts,
boat shows, and other such
competitions, exhibitions, and
events. Also, a number of view
parks have become popular
locations for large private
gatherings. The nature and
frequency of such events has raised
concerns relating to their impact to
coastal resources, public access,
and on adjacent residential areas,
during these events.
Newport Beach regulates temporary events by requiring special event permits. It is
City policy that athletic contests using City streets are not permitted during the
summer (June 15 - September 15). Surfing contests are not permitted during the
- Memorial Day weekend or during the summer. There are also limits on the number
of such events that can be conducted each year and a minimum number of weeks
• between each surfing contest. However, exceptions can be granted.
- Inspiration Point and Lookout Point have become popular locations for weddings and
other events. Peninsula Park is also a popular location for weddings, as well as
company picnics and other private gatherings. Excessive reservations for the use of
these parks has seriously limited public access. Furthermore, the use of these parks
by caterers, party rental companies, professional party, event, or wedding planners
- for private parties presented the appearance of commercialization of public parks.
This prompted the establishment of a policy placing restrictions on reservations from
the Memorial Day weekend to the Labor Day weekend. The number of attendees or
participants at any one time is also restricted.
Policies:
3.1.7 -1. Continue to require special event permits for temporary events and
continue to require applications to provide details on event
characteristics, including duration (including set up /assembly and
break down /dismantle start and completion times), event hours, per
day estimated attendance, parking arrangements, traffic control,
noise control, waste removal, insurance, equipment to be used, food

service, entertainment, sponsorships, and advertising and marketing
plans.
3.1.7 -2. Condition special event permits for temporary uses in the coastal
zone to minimize impacts to public access, recreation and coastal
resources.
3.1.7 -3. Continue to limit the number and frequency of temporary events in
the coastal zone held from the Memorial Day weekend to Labor Day.
3.1.7 -4. Require a coastal development permit for temporary events held in
the coastal zone that meet all of the following criteria:
1. Held between the Memorial Day weekend and Labor Day;
2. Occupy any portion of a public sandy beach area; and
3. Involve a charge for general public admission where no fee is
currently charged for use of the same area.
A coastal development permit shall also be required for temporary
events that do not meet all of these criteria, but have the potential to
result in significant adverse impacts to public access, recreation
and /or coastal resources.

3.1.8 Temporary Closures
For many years, large crowds have
been drawn to the streets of West
Newport during the Independence
Day holiday. The party
atmosphere that pervades the area
attracts these crowds. Large
parties are held at many of the
rental homes in the area, which
often extend into the front yards
and balconies, and even onto
rooftops. The large crowds, the
consumption of alcohol and the
interaction between partygoers and
Independence Day crowds in West Newport the crowds In the streets has
resulted in an average of over 170 arrests and over 1,350 citations each year. The
potential for a serious outbreak of violence exists throughout the daylight hours and
increases dramatically in the evening. This environment dissuades visitors and
residents from enjoying the beach or bay during Independence Day.
The City has tried to reduce illegal drinking and minimize the potential for violence by
significantly increasing the number of police and temporarily closing certain streets to
pedestrians and visitors. The street closures do not restrict access to the beach but
do function to fragment the crowds and reduce the number of people parading along
Seashore Drive - an area where most arrests are made. The street closures are
temporary - typically lasting less than twenty -four hours.
Policies:
3.1.8 -1. Pursuant to the Section 21101 of the Vehicle Code, the City may adopt
rules and regulations regarding the temporary closing of portions of any
street for celebrations, parades, local special events, and other purposes
when necessary for public safety.
3.1.8 -2. The City may temporarily close certain streets in West Newport for a
period of no more than twenty -four hours during the Independence Day
holiday when, in the opinion of the Police Chief or his designee, the
closure is necessary to protect the public safety. In no event shall any
street closure prevent or interfere with the public's access to the beach or
bay.

3.2.1 Recreational Opportunities
Throughout its history, Newport Beach has been a
major recreational center. There are over 8 miles of
sandy beaches that provide opportunities for
sunbathing, volleyball, swimming, suiting, windsurfing
and other recreational activities. Beach attendance
averages 9.4 million people annually. Newport Bay
and Harbor are used for a wide variety of recreational
activities, including boating, diving, excursions,
fishing, kayaking, paddle boarding, parasailing,
rowing, sailing, swimming, and windsurfing.
The City provides approximately 180 acres of public
parks in the coastal zone (see Coastal Access and
Recreation Map). These parks provide areas and
facilities for a variety of recreational activities. The
City also provides two recreational piers. The 800 -
foot Newport Pier is located at the end of Newport
Boulevard (McFadden Place) in McFadden Square.
Beach near Balboa Pier
CITY COUNCIL DRAFT 1 Local Coastal Program

The 950 -foot Balboa Pier is located at the end of Main Street in Balboa Village.
The City also provides ten public docks in the harbor, which can be used for boat
launching and fishing. The City and County also co -own the Newport Aquatic
Center. Located on Northstar Beach, the Newport Aquatic Center provides an
opportunity for the public and members to kayak and canoe in Upper Newport Bay
as well as advanced training facilities for world -class athletes.
The County and the State also operate recreational areas in Newport Beach. The
County's 100 -acre Newport Dunes Aquatic Park provides opportunities for
camping, boating, canoeing, kayaking, swimming and other water and beach
activities. The 752 -acre Upper Newport Bay Marine Park and 140 -acre Upper
Newport Bay Nature Preserve provide opportunities for canoeing, kayaking,
horseback riding, biking, and hiking.
The Fun Zone in Balboa Village
Policies:
Commercial areas adjacent to beaches
and the bay play an important role in
providing and enhancing recreational
activities in the coastal zone. A large
number of businesses provide
recreational services to residents and
visitors of the coastal zone. These include
charter, entertainment and excursion
vessels, sports equipment rentals,
launching facilities, amusement facilities,
and shops and restaurants.
3.2.1 -1. Protect, and where feasible, expand and enhance recreational
opportunities in the coastal zone.
3.2.1 -2. Continue to provide opportunities for a wide range of recreational
activities at City parks and beaches.

3.2.2 Support Facilities and Services
Newport Beach provides abundant coastal access and recreational opportunities.
However, it is equally important to provide adequate support facilities and services to
enable the public to fully avail themselves of these opportunities. Support facilities
include parking, restrooms and showers. Support services include lifeguard services
and instruction and education programs. It is also important that such facilities and
services be well distributed throughout the area to avoid overcrowding or overuse by
the public (see Support Facilities Map).
The lack of informational signage to direct the public to support facilities can
impede public access. Many of Newport Beach's smaller beaches are difficult to
find and access to some coastal areas is not easily apparent due to intervening
topography or development. Furthermore, coastal visitors seeking support
facilities can impact residents and coastal resources. For example, coastal visitors
searching for parking areas contribute to traffic congestion and noise. Visitors
sometimes damage habitats and bluffs to reach coastal areas when paths or trails
are not clearly identified. A comprehensive coastal access signing program will
reduce these impacts and ease conflicts between property owners and coastal
visitors.
Parking
West Newport. West Newport has over a
mile and a half of wide sandy public
beaches. Public parking is provided

The Junior Lifeguard Program continues
to be the most popular program during the
summer months, drawing about 1,200
participants each year. It has provided
invaluable training in water safety
practices and rescue techniques to over
20,000 youths since its inception in 1983,
and is a prime source for identifying future
lifeguards.
Newport Beach offers "beach camps" for
children in the summer months, allowing
children from all communities to enjoy a
week at the beach. Also countless day .junior Lifeguard training
camps visit the beaches for their field trips. Newport Beach also provides instruction
in a number of coastal recreation activities, including volleyball, suiting, and sailing.

program. Tidepool Rangers are trained
volunteers who educate and interact with
visitors to the tide pools. Tidepool
Rangers inform visitors of the rules and
regulations of the Marine Conservation
Area and protect tide pool resources.
The great number and variety of support facilities and services reflects Newport
Beach's commitment to protecting and enhancing public coastal access and
recreational opportunities. However, changes in demographics and recreational
interests have and will continue to alter the public's demand for support facilities and
services. Therefore, it is important that Newport Beach continue to have the ability to
respond to these changes while continuing to provide comparable facilities and
levels of service.

3.3.2 Berthing and Storage
1 e street public dock
Berthing refers to areas or facilities intended for the storage of a vessel in water.
These can involve anchorage and mooring areas, marinas, or individual slips. In
addition to the simple docking or mooring of vessels by their owners, berthing can
also be associated with boat rentals, vessels used in the charter boat industry,
brokered vessels stored for sale, yacht and sailing clubs, and vessels staged for
entry into upland shipyards.
Newport Beach provides over 1,200 bay moorings in the harbor. Approximately 450
are onshore moorings (moorings linked to the beach) and 750 are offshore moorings
(moorings anchored into the Harbor floor). The County Harbor Department provides
a guest mooring area offshore of the Harbor Patrol facility.

Harbor support facilities are uses,
equipment, and vessels that provide
repair, maintenance, new
construction, parts and supplies,
fueling, waste removal, cleaning, and
related services to vessels berthed
in, or visiting the harbor. Harbor
support facilities are considered
essential to maintaining a working
harbor.
Increased environmental regulation
and real estate price inflation in
coastal communities have impacted
Marine service station a number of harbor support
businesses. Those businesses that
do not have to be on the water have moved to inland locations. Those that are more
water dependent have been involved in land use conflicts with residential and other
land uses. Newport Beach has used land use controls as the primary method to
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
3 -36
provide for the continuation of harbor support uses and minimize land use conflicts.
However, additional strategies and incentives may be necessary to protect these
facilities.
Policies:
3.3.3 -1. Protect, and where feasible, expand and enhance facilities necessary
to support vessels berthed or moored in the harbor, such as boat haul
out facilities.
3.3.3 -2. Protect, and where feasible, expand and enhance existing harbor
support uses serving the needs of existing waterfront uses,
recreational boaters, the boating community, and visiting vessels.
3.3.3 -3. In considering the essential nature of land uses that support the
harbor, consider whether or not such support uses can be relocated to
inland locations and /or if technological advances will eliminate the
need such support uses in the foreseeable future.
3.3.3 -4. Support private sector uses, such as vessel assistance, that provide
emergency, environmental enhancement and other services that are
not provided by the public sector and that are essential to the operation
of a working harbor.
3.3.3 -5. Develop strategies to preserve uses that provide essential support for
the vessels berthed or moored in the Harbor. The strategies must be
feasible, cost effective, and respect the property rights of waterfront
owners and lessees. The strategies may include parking waivers,
development transfers, density bonuses and voluntary purchase of
conservation easements.
3.3.3 -6. Develop and implement a signing program to assist owners /operators
of visiting vessels to locate harbor support facilities.

CHAPTER 4
4.0 Coastal Resource Protection
4.1 Biological Resources
Coastal Act policies related to biological resources that are relevant to Newport Beach
include the following:
30230. Marine resources shall be maintained, ertmnced, and, where feasible, restored. special protection shall be
given to areas and species of special biological or economic significance. Uses of the marine environment shall be
carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy
populations of all species of marine organisms adequate for long -term commercial, recreational, scientific, and
educational purposes.
30231. The biological productivity and the quality of coastal waters, streams, wetlands, estuaries, and lakes
appropriate to maintain optimum populations of marine organisms and for the protection of human health shall be
maintained and, where feasible, restored through, among other means, minimizing adverse effects of waste water
discharges and entrainment, controlling runoff, preventing depletion of ground water supplies and substantial
interference with surface waterflow, encouraging waste water reclamation, maintaining natural vegetation buffer areas
that protect riparian habitats, and minimizing alteration of natural streams.
30240. (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat
values, and only uses dependent on those resources shall be allowed within those areas.
(b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation
areas shah be sited and designed to prevent impacts which would significantly degrade those areas, and shall be
compatible with the continuance of time habitat and recreation areas.
4.1.1 Environmentally Sensitive Habitats
Section 30107.5 of the Coastal Act
defines "environmentally sensitive
area' as "any area in which plant or
animal life or their habitats are either
rare or especially valuable because of
their special nature or role in an
ecosystem and which could be easily
disturbed or degraded by human
activities and developments." Section
30240 of the Coastal Act requires that
environmentally sensitive habitat
areas (ESHAs) be protected against
any significant disruption of habitat
values. Only uses dependent on Upper Newport Bay Marine Pak
those resources are allowed within
ESHAs and adjacent development must be sited and designed to prevent impacts
that would significantly degrade the ESHA and must be compatible with the
continuance of the ESHA.
The Coastal Act criteria for determining whether an area qualifies as an ESHA are
based upon ecological importance, including the rarity or function of the habitat,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -1
and the habitat's sensitivity. Rarity relates to either the natural limited occurrence
of the habitat in the region or of the diminishment of what was an extensive habitat
due to cumulative losses. Function relates to the importance of the habitat to the
ecosystem, such as functioning as a migration corridor for wildlife. Sensitivity
relates to the habitats tolerance to disturbance or degradation.
The California Department of Fish and Game (CDFG) California Natural Diversity
Database ( CNDDB) identifies natural communities that are considered rare
because of their highly limited distribution. These communities may or may not
contain rare, threatened, or endangered species. The following CNDDB terrestrial
natural communities are known to occur within the coastal zone in Newport Beach
and the City's sphere of influence:
• Dune habitats, including southern coastal foredunes and southern dune
scrub.
• Scrub habitats, including southern coastal bluff scrub, maritime succulent
scrub, and Diegan coastal sage scrub.
• Chaparral habitats, including southern mixed chaparral and southern
maritime chaparral.
• Riparian habitats, including southern willow scrub, southern coast live oak
riparian forest, southern cottonwood willow riparian forest, southern arroyo
willow forest, southern black willow forest, and southern sycamore alder
riparian woodland.
• Marsh habitats, including coastal brackish marsh, coastal freshwater marsh,
and southern coastal salt marsh.
■ Southern coastal needlegrass grassland.
• Southern hardpan vernal pools.
• Freshwater seeps.
■ Alkali meadows.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -2
In determining whether a habitat area meets the statutory definition of ESHA
contained in Section 30107.5 of the Coastal Act and should be designated as an
ESHA, the following attributes need to taken into consideration:
• The Identification of CDFG /CNDDB natural communities.
• The recorded or potential presence of plant or animal species designated
as rare, threatened, or endangered under State or Federal law.
• The presence of coastal streams or wetlands.
• The degree of habitat integrity /connectivity.
While most of the above habitat characteristics can be documented from a variety
of sources, habitat integrity /connectivity is a more subjective measure of biological
value, which considers various attributes affecting a given habitat's quality in a
particular geographic area. Attributes contributing to or detracting from habitat
integrity include:
• Patch size and connectivity. Large "pieces" of habitat adjacent to or
contiguous with similar or related habitats are particularly useful for more
mobile species that rely on larger territories for food and cover.
• Presence of invasive /non- native species. Invasive /non- native species often
provide poorer habitat for wildlife than native vegetation. Proliferation of
exotic plant species alters ecosystem processes and threatens certain
native species with extirpation.
• Disturbance. This includes disturbance due to human activities such as
access (trails), dumping, vegetation removal, development, pollution, etc.
■ Proximity to development. Habitat areas bordering development provide
marginal habitat values to wildlife due to impacts from negative edge
effects. This proximity presents the possibility of secondary effects to the
habitat due to spillover or human intrusion. Deterioration of habitat results
from intrusion of lighting, non - native invasive plant species, domestic
animals, and human activity.
■ Fragmentation. The converse of "connectedness ", habitat fragmentation is
the result of development of large blocs of undisturbed, contiguous habitat.
The resulting breaking up of these areas into isolated, disjunct parcels can
create barriers to migration, reduce wildlife food and water resources and
generally compress territory size to reduce existing wildlife populations to
non - viability. Fragmentation increases negative edge effects, whereby the
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -3
interior area of habitat is affected by the different conditions of the
disturbance on its edges. The smaller a particular habitat is, the greater the
proportion of its area which experiences the edge effect, and this can lead
to dramatic changes in plant and animal communities. In general, loss of
habitat produces a decline in species total population size, and
fragmentation of habitat can isolate small subpopulations from each other.
If, based on site - specific analysis by a qualified biologist, a habitat area is
degraded beyond the point of restoration or is isolated in a manner that it no
longer has habitat value or a special nature or role in the ecosystem, the habitat
area does not meet the statutory definition of ESHA contained in Section 30107.5
of the Coastal Act. Therefore, such habitat areas do not warrant the special land
use and development restrictions of Section 30240 of the Coastal Act.
Policies:
Define any area in which plant or animal life or their habitats are
either rare or especially valuable because of their special nature or
role in an ecosystem and which could be easily disturbed or
degraded by human activities and developments as an
environmentally sensitive habitat area (ESHA). Using a site - specific
survey and analysis by a qualified biologist, evaluate the following
attributes when determining whether a habitat area meets the
definition of an ESHA:
A. The Identification of CDFG /CNDDB natural communities.
B. The recorded or potential presence of plant or animal species
designated as rare, threatened, or endangered under State or
Federal law.
C. The presence of coastal streams or wetlands
D. The degree of habitat integrity /connectivity.
Attributes to be evaluated when determining a habitat's
integrity /connectivity include the habitat's patch size and
connectivity, the presence of invasive/non- native species, the level of
disturbance, the proximity to development, and the level of
fragmentation.
Existing developed areas and fuel modification areas required by the
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -4
City of Newport Beach Fire Department or the Orange County Fire
Authority for existing, legal structures do not meet the definition of
ESHA.
4.1.1 -2. Require a site - specific survey and analysis prepared by a qualified
biologist as a filing requirement for coastal development permit
applications where development would occur within or adjacent to
areas identified as a potential ESHA.
4.1.1 -3. Design and site new development, including landscaping, to protect
ESHAs against any significant disruption of habitat values.
4.1.1 -4. Design land divisions, including lot line adjustments, to preclude new
development within and minimize impacts to ESHAs.
4.1.1 -5. Limit uses within ESHAs to only those uses that are dependent on
such resources, except where application of such a limitation would
result in a taking of private property. If the application of ESHA
policies would likely constitute a taking of private property, then a
non - resource dependent use shall be allowed on the property,
provided development is limited to the minimum amount necessary
to avoid a taking and the development is consistent with all other
applicable resource protection policies.
4.1.1 -6. Public access improvements and educational, interpretative and
research facilities are considered resource dependent uses.
4.1.1 -7. Where feasible, confine development adjacent to ESHAs to low
impact land uses, such as open space and passive recreation.
4.1.1 -8. Maintain a buffer of sufficient size to ensure the protection of ESHAs.
4.1.1 -9. Require the use of native vegetation and prohibit invasive plant
species within ESHAs and ESHA buffer areas.
4.1.1 -10. Shield and direct exterior lighting away from ESHAs to minimize
impacts to wildlife.

4.1.2 Marine Resources
Marine Habitats
Newport Beach and surrounding
ocean waters have very diverse
marine habitats. These include
the marshes and wetlands in
Upper Newport Bay, the
developed channels, beaches,
and hard structures (bulkheads,
seawalls, docks, pilings, and
jetties) of Lower Newport Bay,
and the intertidal and subtidal
landforms (sandy beaches, rocky
intertidal, sandy subtidal, and
subtidal reefs) along the coast of
Newport Beach Marine ConservaUOn Area Newport Beach. Section 30230 of the Coastal Act requires that
marine resources be maintained, enhanced, and, where feasible, restored.
Protection of marine habitats is required not only for their biological significance,
but also for their commercial, recreational, scientific, and educational value.
Open estuary and salt marsh habitats occur in the Upper Newport Bay and the
Semeniuk Slough. The Upper Newport Bay is one of the largest coastal wetlands
remaining in southern California and is an ecological resource of national
significance. The Semeniuk Slough is a relatively large, uninterrupted open
estuary/coastal salt marsh that provide wildlife with a relatively large, diverse area
for foraging, shelter, and movement. The habitats of the Semeniuk Slough and
the Upper Newport Bay are discussed further in Section 4.1.3 (Environmental
Study Areas).
Eelgrass (Zostera marina) is a marine plant that grows in Newport Harbor at
depths below the low tide line and into the navigational channels. This true marine
grass forms meadows and attracts many invertebrates and fishes that use the
vegetation as foraging and nursery habitat. Eelgrass is discussed in more detail in
Section 4.1.4 (Eelgrass Meadows) and Section 4.2.5 (Eelgrass Protection and
Restoration).
The Newport Beach Marine Conservation Area is located along the Corona del
Mar shoreline and extends 200 feet offshore. Numerous types of invertebrates,
algae, seagrass, fishes, and seabirds occur within the limits of the refuge, and
marine mammals occasionally pass through. The Newport Beach Marine
Conservation Area is discussed further in Section 4.1.3 (Environmental Study Area
11).

The Newport Submarine
Canyon is a unique coastal
feature that begins immediately
seaward of the Newport Pier at
a depth of 8 meters (25 feet).
Bottom depths rapidly increase
to nearly 30 meters (100 feet)
within 400 meters (1,200 feet)
from shore and 100 meters
(300 feet) deep within 1,300
meters (3,900 feet) from shore.
This geological feature is
believed to have been formed
by the ancestral Santa Ana
River, and it is the exit pathway Rwresemaaon of the Newpot submarine Canyon
for southward - moving sands
transported through littoral drift currents at the end of the San Pedro Littoral Cell.
In an effort to reduce the sand loss, the U.S. Army Corps of Engineers constructed
six groins along West Newport to hold the sand. The groins have been partially
successful. Biologically, the submarine canyon is unique because it acts as a
pathway for cold, nutrient -rich waters that upwell from deeper offshore waters to
the shallower nearshore shelf. Additionally, the canyon acts as a pathway through
which deeper water species of fish, squid, shark, and jellyfish, sometimes can be
found close to shore. The canyon is also an important fishing zone for the Dory
Fishing Fleet.
Sensitive Marine Species
Several species of marine mammals frequent the nearshore waters along the
Newport Beach coastline. All marine mammals are protected by the Marine
Mammal Protection Act. Several whales are federally listed endangered species.
The marine mammals that have the greatest potential to occur locally are
California sea lion (Zalophus californicus), harbor seal (Phoca vitulina), California
gray whale (Eschrichthius robustus), killer whale (Orcinus orca), common dolphin
(Delphinus delphis), bottlenose dolphin (Tursiops truncates), Pacific white sided
dolphin (Lagenorhynchus obliquidens), and Dall's porpoise (Phocenoides dalh).
The most common, the California gray whale, was delisted as an endangered
species in 1994 because of significant increases in its population numbers in
recent years. California gray whales are common between December and April, as
they migrate between their summer feeding grounds in the Bering Sea and their
Baja California calving lagoons. Individuals sometimes enter the Newport Harbor
Entrance Channel. Pods of bottlenose dolphin are occasionally observed
swimming in the surf zone or immediately outside the surf zone along the Newport
coastline. California sea lions are frequently observed within Newport Harbor,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan

particularly in the vicinity of the sports fishing boats near the Balboa Pavilion.
Although giant kelp (Macrocystis pyrifera) beds do not have official status as a
sensitive habitat or resource, kelp forests afford protection and cover for many
marine invertebrates and fishes. Giant kelp currently is rare within the Newport
Beach and Irvine Coast Marine Conservation Areas, although historically it has
occurred along the coastline between Coronal del Mar and the Newport Coast.
Diebacks of kelp have occurred periodically along the southern California Coast
primarily during warm water El Nino periods. However, kelp beds along the
Newport to northern Laguna coastline have failed to regenerate in recent years
and the reasons for this occurrence are not clear. Increases in sediment loads
along the coast due to urban runoff may be a contributing factor, along with
periodic large storm events that dislodge plants, sustained warmer waters
temperatures during El Nino periods, and over fishing. During 2002, there were
excellent conditions for giant kelp in southern California. Mild winters and cold,
nutrient -rich waters enabled many kelp beds to recover naturally and rapidly.
However, Orange County saw very little natural recovery. A number of giant kelp
reforestation projects are being attempted in southern California, including one in
the Crystal Cove State Underwater Park.
Despite the
substantial
declines in the distribution of
giant kelp cover
along the
shoreline between
Corona del
Mar and Laguna
Beach, a
stand of giant
kelp has
maintained itself within
Newport Harbor
Entrance
Channel, along the
west jetty.
The giant kelp
bed is
discussed further
in Section
4.1.3 (Environmental Study
Area 13).
Kelp beds and associated reef organisms in the Newport Harbor ra55 iiOS aX S
Entrance Channel Surf Ph dlPP ) is
g ( Y p
a sensitive marine resource that
occurs in rocky shoreline and rocky subtidal habitats at depths to approximately —
20 feet MLLW. Its sensitivity is related to its use by invertebrates and fishes as
nursery habitat and its susceptibility to long -term damage because it is a very slow
growing species. Revegetation occurs naturally through seeding and eventually
spreading of roots and rhizomes over surfaces of rocks. Surfgrass is located
within the Newport Beach Marine Conservation Area, along the outer fringes of the
intertidal reefs and the tops of shallow subtidal reefs.
California grunion (Leuresthes tenuis) are fish that are associated with many

beaches in southern California. Grunion lay their eggs in the wet beach sands
during the highest spring tides between late February or early March, to as late as
early September. Historically, these grunion "runs' have occurred on west- facing
beaches upcoast of Newport Pier, where the beach slopes tend to be more
gradual rather than south facing beaches downcoast of Newport Pier. However,
there has been no recent grunion activity observed on these beaches. Grunion
run activity has also occurred on Corona del Mar State Beach and Rocky Point
Beach, in the Harbor Entrance mouth.
Although California halibut (Paralichthys californicus) does not have a formal
special species status, the California halibut is considered a sensitive species by
resource agencies because of its commercial value and a continued region -wide
reduction of its nursery habitat in bays and wetlands. California halibut spawn at
sea and the larval stages are planktonic. After several months, the larval fish
settle to the bottom, and migrate into shallow coastal waters, including Newport
Bay. Halibut are distributed throughout the waters of Lower and Upper Newport
Bay, primarily as juveniles, although larger individuals are caught near the ocean
entrance and offshore. Young -Of- The -Year (YOTY) prefer shallow waters
between about —0.45 meter (1.5 feet) and —1.0 meter (3.5 feet) Mean Lower Low
Water (MLL", whereas juveniles prefer deeper channel bottoms to a maximum
depth of approximately 4.5 meters (15 feet) MLLW. After spending nearly nine
months in Newport Bay, juveniles will move out into the open coastal environment.
Invasive Marine Species
Caulerpa taxifolia is an extremely harmful, invasive species that has recently been
introduced into southern California waters. It has been located within Huntington
Harbour and in the Agua Hedionda Lagoon in northern San Diego County. This
species has a characteristic bright green color, flat, leafy fern -like fronds
(branches), and below - ground root system. Caulerpa algae can be extremely
harmful to marine ecosystems because it invades and out - competes native
habitats by forming a dense blanket of growth on mud, sand, or rock surfaces. It
can grow in shallow coastal lagoons as well as in deeper ocean waters, and can
grow rapidly and up to 9 feet in length. However, its usual form observed so far is
much smaller in length.
The ecological consequences of the spread of this invasive algae can be
extremely serious and can result in a significant loss of plant and animal
productivity. Therefore, the spread of this species is being closely monitored and
areas that have become infested are being treated chemically to eradicate any
growth. The management, control, and eradication of this species is the
responsibility of the Southern California Caulerpa Action Team (SCCAT).
Newport Bay is not currently known to be infested by this species, however,
continued surveillance for undetected or new infestations is a high priority to the
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -9
SCCAT. Project site surveys for the presence of Caulerpa taxifolia are required
by NOAA and CDFG prior to bottom - disturbing projects such as dredging, dock
replacement, bulkhead repair.
Assembly Bill 1334 (Chapter 338, Statutes of 2001) prohibits the sale, possession,
and transport of Caulerpa taxifolia throughout California. The Bill also bans
species of Caulerpa that look similar to C. taxifolia and are believed to have the
capability to become invasive. The importation of the Mediterranean strain of
Caulerpa taxifolia into the United States and interstate trade, including via the
Internet, is also a federal offense under the Federal Noxious Weed Act of 1999
and the Plant Protection Act of 2000.
Water Quality
Runoff from the surrounding watershed threatens the biological diversity and
functionality of Newport Bay and the surrounding coastal waters. This runoff
includes various pollutants, such as fecal material from pets, oil and grease,
fertilizers, and other urban -based pollutants. In addition, increased sediment loads
decrease the extent of tidal inundation, diminish water quality, degrade habitat for
endangered species, migratory water birds, and marine and estuarine fishes, and
contribute to the decline of kelp forests. Water quality and sedimentation issues
are discussed further in Section 4.2 (Wetlands and Deepwater Areas) and Section
4.3 (Water Quality).
Policies:
4.1.2 -1. Maintain, enhance, and, where feasible, restore marine resources.
4.1.2 -2. Provide special protection to marine resource areas and species of
special biological or economic significance.
4.1.2 -3. Require that uses of the marine environment be carried out in a
manner that will sustain the biological productivity of coastal waters
and that will maintain healthy populations of all species of marine
organisms adequate for long -term commercial, recreational,
scientific, and educational purposes.
4.1.2 -4. Continue to cooperate with the state and federal resource protection
agencies and private organizations to protect marine resources.
4.1.2 -5. Continue to require Caulerpa protocol surveys as a condition of City
approval of projects in the Newport Bay and immediately notify the
SCCAT when found.

4.1.3 Environmental Study Areas
Newport Beach has several relatively large, undeveloped areas that contain
natural habitats and may be capable of supporting sensitive biological resources.
These areas are designated as environmental study areas to define them
geographically, provide an overview of known and potential biological resources,
identify potential threats to those resources, and propose potential mitigation
measures.
The following areas are designated as environmental study areas:
1. Semeniuk Slough (Santa Ana River Marsh)
2. North Star Beach
3. West Bay
4. Upper Newport Bay Marine Park and DeAnza /Bayside Marsh Peninsula
5. San Diego Creek
6. Eastbluff Remnant
7. Mouth of Big Canyon
8. Newponer North
9. Buck Gully
10. Morning Canyon
11. Newport Beach Marine Conservation Area
12. Castaways
13. Kelp Beds in Newport Harbor Entrance Channel
Most of these study areas are protected as parks, conservation areas, nature
preserves, and other open space areas. Nevertheless, the natural habitats in
each of these study areas are subjected to various potential impacts from the
surrounding urban environment. Potential adverse impacts and mitigation
measures to reduce those impacts identified in the narratives below and
summarized in Table 4.1 -1 (Environmental Study Area Environmental Impacts and
Mitigation Measures).
Eelgrass meadows within Newport Bay and coastal foredunes on the Balboa
Peninsula are not included in the list of environmental study areas since their
locations shift due to fluctuations in growing conditions. Eelgrass meadows and
coastal foredune habitats are discussed in Section 4.1.4 and Section 4.1.5,
respectively.

Study Area No. 1: Semeniuk Slough
Semeniuk Slough is a remnant channel of the Santa Ana River from the time when
the river emptied into Newport Bay; it forms a loop around the Newport Shores
residential area in West Newport. The 103 -acre Semeniuk Slough Environmental
Study Area (ESA) includes the main slough channel immediately north of Newport
Shores and the coastal salt marsh habitat to the north, including a narrow sliver of
salt marsh habitat in the far north of the ESA, flanked by the Santa Ana River on
the west and Banning Ranch on the east. Several smaller interconnected channels
and inundated depressions are located throughout the salt marsh habitat.
Semeniuk Slough is exposed to limited tidal
influence through a tidal culvert connected
between the Santa Ana River and the
slough. The site contains a healthy stand of
sensitive coastal salt water marshhabitat .
The state endangered Belding's savannah
sparrow (Passerculus sandwichensis
beldingi) breeds in nearby wetland habitats
including Upper Newport Bay and salt
marsh in Huntington Beach but not in
Semeniuk Slough. However, small
Semeniuk Slough numbers of Belding's savannah sparrows
forage in Semeniuk Slough, especially during
the winter when breeding birds disperse. A Belding's savannah sparrow was
observed within the Semeniuk Slough site on July 10, 2002. The state and federal
endangered California least tern (Sterna albifrons brown), which has a large
nesting colony on the Huntington Beach side of the Santa Ana River mouth,
forages occasionally in the slough channels. Western snowy plovers (federal
threatened) are observed occasionally in Semeniuk Slough. The California
brackish water snail (Tryonia imitator), a Federal Species of Concern, has been
collected in substantial numbers in the channels of Semeniuk Slough.
The Semeniuk Slough ESA is characterized by open estuarine, southern coastal
salt marsh, and ornamental plant communities. The S- curved channel, also
referred to as Oxbow Loop, is bordered to the north by southern coastal salt marsh
vegetation, which is dominated by pickleweed (Salicomia sp.) and salt grass.
Most of the natural areas occur to the west of the parcel. Sea fig has invaded
some of the upland portions of the parcel. Other ornamental plant species are
found along the margin of the Slough, primarily in the eastern portions of the
parcel and include myoporum ( Myoporum sp.), acacia (Acacia sp.), Mexican fan
palm, pine (Pinus sp.), and eucalyptus.
Many houses in the Newport Shores development bordering the slough have small
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -12
docks and patios that encroach into the slough. The proximity to the Newport
Shores residential development has introduced numerous ornamental and non-
native species to the eastern perimeter of the site, and also allows use of the
slough for recreational use. A few oil -well related structures are located in the
southern part of the ESA, immediately north of the main slough channel. The land
surrounding these structures has been cleared. Two roads bisect the study area -
one leading from the Santa Ana River levee to the Banning Ranch area, and the
other leading to the oil well structures.
Potential impacts to this area include water quality degradation, human activity,
encroachment, invasive species, and uncontrolled public access.
Studv Area No. 2: North Star Beach
Located at White Cliffs Drive and
North Star Lane, North Star Beach is
bordered by the main channel of
Upper Newport Bay to the east,
Galaxy Drive to the north, and
residential development to the south

including birds, amphibians, and mammals. Sensitive species, such as the least
Bell's vireo and southwestern willow flycatcher, have the potential to occur within
this site.
The beach parcel located south of the Newport Aquatics Center (NAC) consists of
dredged sand material and supports predominately ruderal plant species including
cheeseweed (Malva pariflora), red - stemmed fflaree (Erodium cicutarium), sea
rocket, and black mustard (Brassica nigra). The bluff located to the west of the
beach and the NAC facilities, and east of the adjacent residential area supports
several non - native ornamental trees and shrubs including acacia, myoporum, and
pine. Several saltbush shrubs are located throughout the sandy beach and bluff
areas within this parcel. A small wetland supported by nuisance water runoff (from
the western bluffs and residential area) is located just north of the NAC facilities.
This area mainly supports willow (Salix spp.), palm (Phoenix sp.), and sedge.

North of where the wetland reaches the bay, native saltwater marsh and southern
coastal bluff scrub habitat is found that lacks the exotic species present in the
southern portion of the study area.
Potential impacts to the natural habitats in this study area include erosion,
increased human activity, ambient noise, invasive species, and uncontrolled public
access.
Study Area No. 3: West Bay
The 84.4 -acre West Bay ESA is located
along Irvine Avenue from University
Drive south along the east side of
Galaxy Drive. It is bordered by the
Upper Newport Bay Marine Park to the
east, residential development to the
north and west, and the North Star
Beach ESA to the south.
This parcel consists of four
characteristic plant communities,
including Diegan coastal sage scrub,
at Upper Newport and Dieganeoastal sage sauD habitat southern coastal bluff scrub, disturbed
a[ Upper Newport Bay Naare Preserve
southern willow scrub, and non - native
grassland. Much of the non - native grassland was most likely remnant coastal
sage scrub habitat prior to being cleared. The Dieagan coastal sage scrub habitat
is located primarily near the bay, with a few stands that border Irvine Avenue, and
is primarily composed of California sagebrush, coyote brush, prickly pear
(Opuntia sp.), coast goldenbush (Isocoma menziesii var. menziesit), and
lemonadeberry.
The southern section of the study area overlooking the bay supports southern
coastal bluff scrub vegetation. Plant species associated with this area include
saltbush, tree lupine (Lupines arborous), prickly pear, coyote brush, California
buckwheat, coastal goldenbush, and California bush sunflower. This area is
contiguous with the bluff habitat along North Star Beach.
A small drainage located near 23rd Street (the remnant of Indian Springs)
transports nuisance water runoff from the residential area located west of Irvine
Avenue, and crosses the southern portion of the West Bay ESA before reaching
the bay. This drainage supports a disturbed southern willow scrub plant
community dominated by willow, eucalyptus, and giant reed. Several coastal sage
scrub restoration areas, revegetated with young native shrubs, are located along

the gradual slopes located north of the drainage. Black mustard and wild oats
dominate the non - native grassland plant community, which is found throughout the
parcel and most often bordering Irvine Avenue.
This site is used as open space as well as for recreational opportunities and
includes the Muth Interpretive Center operated by the County of Orange. A paved
bike and pedestrian trail is located along the crest of the West Bay parcel. Several
dirt trails transect the north end of the parcel.
Potential impacts to the natural habitats in this study area include erosion,
increased human activity, ambient noise, invasive species, and uncontrolled public
access.

Upper Newport Bay, one of the largest coastal wetlands remaining in southern
California, is an ecological resource of national significance. Sensitive natural
habitats within Upper Newport Bay include estuarine marine open water, coastal
freshwater marsh, intertidal mudflat, salt panne, Diegan coastal sage scrub, and
southern coastal salt marsh. Salt marsh habitat within Upper Newport Bay
includes cordgrass- dominated low salt marsh, pickleweed- dominated mid salt
marsh, and high salt marsh.
This ESA supports several listed bird species and an endangered plant. The
resident population of the state and federal endangered light- footed clapper rail

Coastal Land Use Plan
4 -15
(Rallus longirostris levipes) in Upper Newport Bay represents about 65 percent of
the California population of this species. Upper Newport Bay has consistently
supported the highest numbers of rails of any southern California wetland, and is
believed to be the only viable subpopulation remaining in the United States. The
highest number of breeding clapper rails during the 1990s in Upper Newport Bay
was 158 pairs in 1996. The 1999 census recorded 104 pairs. Low salt marsh
dominated by cordgrass is the species' preferred nesting habitat, but it has been
known to breed in brackish and even freshwater marsh. Clapper rails are found
throughout the Upper Bay, heavily utilizing cordgrass marsh for nesting at several
locations, including Shellmaker Island, Middle Island, Upper Island, and salt marsh
habitat above the Main Dike.
The state endangered Belding's
savannah sparrow is a year -round
resident and breeder in Upper Newport
Bay. Its preferred nesting habitat is
pickleweed- dominated mid salt marsh. In
1996, the population in Upper Newport
bay was 252 pairs.
The state and federal endangered
California least tern is a seasonal
resident in Upper Newport Bay from April
to early September. They nest on Least
De AnzalBayside Marsh Peninsda Tern Island, the smaller of two islands in
the uppermost sedimentation basin. In
1999, 40 pairs of least terns nested on this island. In 2000, 60 least tern pairs
nested in Upper Newport Bay and fledged 12 young. Skimmers and Forsters
terns nest on the second, and larger island (Skimmer Island) in the uppermost
sedimentation basin.
The federally threatened coastal California gnatcatcher nests in coastal sage scrub
along the margins of Upper Newport Bay. There are at least 10 pairs breeding in
upland habitat surrounding Upper Newport Bay.
Other listed bird species that occur in Upper Newport Bay on a seasonal basis but
do not breed there include the state and federal endangered California brown
pelican, the federal threatened western snowy plover, and the state endangered
American peregrine falcon.
The state and federal endangered plant salt marsh bird's beak occurs at several
sites in high salt marsh habitat in Upper Newport Bay. It is the only listed plant
species confirmed to occur in the Upper Newport Bay Marine Park.
CITY COUNCIL DRAFT 1 Local Coastal Program

In addition to these listed species, a number of bird species that are Federal
Species of Concern and /or State Species of Special Concern use the Upper
Newport Bay Marine Park. The California brackish water snail, a Federal Species
of Concern, is common around freshwater discharges to the Upper Bay.
Because of its diversity of habitats and its location on the Pacific Flyway, Upper
Newport Bay supports an impressive number and diversity of birds, particularly
during fall and winter when shorebirds and waterfowl arrive from their northern
breeding grounds. There are approximately 182 bird species that regularly occur
in Newport Bay over a calendar year. Only about 18 percent of these are year
round residents. The large number of non - resident bird species indicates Newport
Bay's value not only to the local resident bird community, but also to a large
number of migratory gulls, terns, raptors, shorebirds and waterfowl that are key
species in ecosystems in other areas of the continent.
At least 78 fish species have been identified in various studies of Upper Newport
- Bay. Newport Bay is an important habitat for resident estuarine species, as well
as a spawning and nursery ground for a variety of marine species including
California halibut (Paralichthys californicus), yellowfiin croaker, white seabass
(Atractoscion nobilis) and barred sandbass.
The ecological diversity and functionality of the Upper Newport Bay Marine Park
has been threatened by sedimentation from the surrounding watershed. The
primary source of freshwater and sediment loads to Upper Newport Bay is San
Diego Creek. Sediment from the San Diego Creek watershed has filled open
water areas within the Bay. This sedimentation has decreased the extent of tidal
inundation, diminished water quality, degraded habitat for endangered species,
migratory water birds, and marine and estuarine fishes. Heavy sedimentation
during the 1998 El Nino required dredging in 1998 and 1999. Recently, a long-
term management plan was developed to control sediment deposition in the Upper
Bay to preserve the health of Upper Newport Bay's habitats. That plan identified
basin configurations and depths to control sedimentation in the Upper Bay.
The slopes of the bluffs along Upper Newport Bay are unstable and have required
stabilization devices and bluff repairs. Irrigation practices on the tops of the bluffs
have contributed to both erosion and eutrophication problems in the Upper Bay.
Study Area No. 5: San Diego Creek
The 37.3 -acre San Diego Creek ESA is bordered by Jamboree Road to the west,
Bayview Way and a commercial automobile dealership to the north, MacArthur
Boulevard to the east, and the residential area adjacent to University Drive on the
south. The San Diego Creek site is contiguous with the Upper Newport Bay
Marine Park, and merges with the bay in the vicinity of Jamboree Road. This
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan

study area includes two main parcels: the main channel of San Diego Creek and
an adjacent saltwater marsh mitigation area located to the north.
The San Diego Creek study area is
dominated by southern willow
scrub and southern coastal salt
marsh communities. These
habitats are considered sensitive,
and are listed as rare or threatened
or are otherwise protected by the
USFWS, CDFG, or local agencies.
Southern willow scrub is utilized by
many species of vertebrates
including birds, amphibians, and
mammals. Sensitive species, such
as the least Bell's vireo and
southwestern willow flycatcher, Main channel of San Diego Creek
have the potential to occur within
this site. Southern coastal salt marsh also provides habitat for many sensitive
plants and animals, which have the potential to occur within this site. The
California brackish water snail, a Federal Species of Concern, is common around
freshwater discharges to the Upper Bay, including San Diego Creek.
The marsh site is separated from the main channel by an earthen levee, but is
hydraulically recharged by San Diego Creek during high water events through an
existing culvert. The marsh site consists of two primary habitat types: southern
coastal salt marsh (aquatic) and southern willow scrub. The middle of the site is
inundated with low -to- moderate amounts of water, and is dominated by salt marsh
and emergent wetland vegetation including pickleweed, salt grass, and bulrush
(Scirpus sp.). Portions of this area have been revegetated with native plants. The
eastern portion of the site gives rise to southern willow scrub and primarily
consists of willow (Salix sp.), mule fat, and cattails. The upland areas of this site
support a mixture of habitat types and consist of shrub species, including
California bush sunflower, saltbush, and mule fat.
The main channel is characterized by southern willow scrub. This area is
dominated by willow and mule fat, and supports a few isolated cottonwood trees
(Populus sp.). Two exotic species, giant reed and brass buttons, are commonly
found throughout the riparian zone.
Potential impacts to the natural habitats in this study area included human activity,
ambient noise, invasive species, and uncontrolled public access.

Southern coastal bluff scrub at Eastbluff Remnant
The 36.5 -acre Eastbluff Remnant
ESA extends along the eastern side
of Back Bay Drive from Jamboree
Road to Eastbluff Drive, and is
bordered by Upper Newport Bay to
the north and west, residential
development to the east, and San
Joaquin Hills Road to the south.
This study area consists of three
main plant communities, including
southern coastal bluff scrub, Diegan
coastal sage scrub, and southern
willow scrub.
Most of the study area consists of steeply sloped west - facing bluffs. The areas
support mainly southern coastal bluff scrub vegetation with some evidence of
Dieagan coastal sage scrub species. Plant species associated with this area
include saltbush, tree lupine, coastal goldenbush, California bush sunflower,
coyote brush, California buckwheat, prickly pear, cholla (Opuntia sp.), California
sagebrush, and lemonadeberry.
There are varying degrees of previous disturbance, mostly resulting from the
adjacent residential area to the east. Several non - native species are found
throughout these areas, including sea fig, tree tobacco, sweet fennel (Foeniculum
vulgare), black mustard, and castor bean.
The Dieagan coastal sage scrub habitat dominates the upper, less steep portions
of the parcel, and is primarily composed of California sagebrush, coyote brush,
prickly pear, and Mexican elderberry, poison oak, and lemonadeberry.
Southern willow scrub vegetation may be found within several tributaries to
Newport Bay and along the eastern edge of Back Bay Road, where water
accumulates before entering the bay. These areas are dominated by willow and
mule fat. Dense stands of Mexican elderberry, willow, and poison oak dominate
the north - facing slopes in the northeastern portion of the East Bluff parcel.
Potential impacts to the natural habitats in this study area include erosion,
increased human activity, ambient noise, invasive species, and uncontrolled public
access.

Study Area No. 7: Mouth of Bia Canyon
The 52.0 -acre Big Canyon ESA is
located on the east side of Newport
Bay, between Back Bay Drive and
Jamboree Road. The Mouth of Big
Canyon site is bordered by Upper
Newport Bay to the west and
residential development to the east,
north, and south of the site.
Many trails throughout this area
provide good access for the public to
observe the variety of habitats and
Fresh water marsh at the mouth of Big Canyon plant communities. The backbone
routes for these trails are utility access
roads needed to provide access for maintenance vehicles that service the utilities
that have been installed in this site. This site provides an opportunity to establish
an interpretive area that allows public access to a broad range of habitats and
plant community areas that should be reestablished as a destination for the public.
Seven plant communities characterize this site, including southern willow scrub,
Diegan coastal sage scrub, non - native grassland, southern coastal bluff scrub,
southern coastal salt marsh, southern cottonwood willow riparian forest, and
coastal freshwater marsh.
Big Canyon is oriented perpendicular to the bay. The upper (eastern) portion of
the creek supports native plants characteristic of southern willow scrub
communities dominated by densely growing willows and mule fat. The upland
areas within the eastern region contain a mixture of disturbed Diegan coastal sage
scrub and non - native grassland. Plant species found in this area include coyote
brush, lemonadeberry, black mustard, and sweet fennel. The canyon is outlined
by intermittent stands of ornamental trees and shrubs including eucalyptus and
acacia, which are located next to the adjacent residential zones.
The mouth of the canyon widens towards the bay and supports a mixture of
southern coastal bluff scrub and Diegan coastal sage scrub along both the north
and south - facing slopes. These areas are dominated by California sagebrush,
California buckwheat, prickly pear, saltbush, lemonadeberry, and Mexican
elderberry.
The western reach of the canyon creek forms a pond, while supporting a mature
southern cottonwood willow riparian forest and coastal freshwater marsh. Fremont
cottonwood (Popu/us fremonfii spp. fremonfit), western sycamore, and willow
dominate the overstory of the riparian forest. Stinging nettle (Urtica diocia) can be

found amongst the herbaceous layer. The northern margins of the riparian forest
show evidence of dryer climates and supports revegetated species such as holly -
leaf redberry and jojoba (Simmondsia chinensis). The coastal freshwater marsh is
surrounded by cattail and sedge.
Remnants of the southern coastal salt marsh habitat are evident on the dredge sand
deposits located immediately south of the freshwater marsh, where pickleweed is
the dominant plant species.
Potential impacts to the natural habitats in this study area include erosion, creek
water quality runoff, sedimentation, erosion, increased human activity, ambient
noise, invasive species, and uncontrolled public access.
Studv Area No. 8: Newporter North
The Newport North is located in bluff
and mesa habitats along Back Bay
Drive and San Joaquin Hills Road
adjacent to Upper Newport Bay.
The 49.2 -acre Newporter North ESA
is bordered by Upper Newport Bay
to the west, the Hyatt Newporter
Hotel to the south, Jamboree Road
to the east, and residential
development to the east and north of
the site.
The Newporter North ESA is
characterized by five plant Diegan coastal scrub on the slopes of Newporter North
communities, including southern
willow scrub (disturbed), coastal freshwater marsh, Diegan coastal sage scrub,
southern coastal bluff scrub, and non - native grassland.
A drainage (John Wayne Gulch) runs east to west from Jamboree Road to the
bay. The upper (eastern) portion of the drainage supports native plant species that
are characteristic of southern willow scrub communities including willows, mule fat,
and Mexican elderberry. This drainage also supports many exotic species
including myoporum, tree tobacco, eucalyptus, pampas grass (Cortaderia
selloana), and sweet fennel. The lower (western) portion of the drainage widens
into a coastal freshwater marsh before reaching the bay. This area is thickly
vegetated and dominated by cattail, sedge, and brass buttons. Additionally, there
is a wetland restoration area located in the far northeast portion of this parcel,
which is dominated by willows, mule fat, and cattails.
Diegan coastal sage scrub occurs at higher elevations within the parcel along the

south and north- facing slopes. Plant species associated within this area include
California sagebrush, coyote brush, California bush sunflower, California
buckwheat, Mexican elderberry, coastal goldenbush, and deerweed. An area
located just south of San Joaquin Hills Road supports densely growing coastal
sage scrub vegetation. A small square parcel of coastal sage scrub bordered by
Newporter Way and Jamboree Road is found within this section of the study area.
The steeper west - facing slopes, located above Back Bay Drive to the north and
south of the main canyon, support southern coastal bluff scrub vegetation. Plant
species associated with this area include saltbush, tree lupine, prickly pear,
coyote brush, California buckwheat, coastal goldenbush, and California bush
sunflower.
Historically, most of the upland areas located in the southwestern portion of the
parcel most likely supported coastal sage scrub communities; however land
modification and clearing has disturbed these areas, leaving many sections
supporting only non - native grasslands. Common species found within the non-
native grassland community include black mustard, white sweetclover (Melilotus
alba), artichoke thistle (Cynara cardunculus), and pampas grass.
Potential impacts to the natural habitats in this study area include erosion,
increased human activity, ambient noise, invasive species, and uncontrolled public
access.
Studv Area No. 9: Buck Gullv
Buck Gully is a natural feature extending between Little Corona Beach and the
San Joaquin Hills. The 74.2 -acre Buck Gully ESA does not include the sections of
the canyon that are located outside of the coastal zone or within Newport Coast.
The ESA is bordered by the Pacific Ocean to the southwest, and residential and
commercial development to the southeast, northwest, and north of the site. Pacific
Coast Highway bisects the canyon. Drainage from Buck Gully empties on to Little
Corona Beach. The portion of Buck Gully between the extension of Fifth Avenue
and Little Corona is under private ownership.
The Buck Gully ESA is dominated by Diegan coastal sage scrub and southern
mixed chaparral, with southern willow scrub, annual grassland, and coastal
freshwater marsh occurring as smaller components of the community. Diegan
coastal sage scrub and southern mixed chaparral encompass the majority of the
gully - from the upper rims to the alluvial bottoms. A narrow ribbon of southern
willow scrub riparian habitat is supported by an unnamed creek that flows along
the canyon bottom the length of the gully. Patches of annual grassland occur
throughout the chaparral and coastal sage scrub habitats and also in areas where
native vegetation has been cleared for fire prevention. The narrow, western reach
of the canyon is largely encroached upon by the adjacent residential areas to the

southeast and northwest. The upper
slopes in this area of the canyon
support a mix of disturbed southern
mixed chaparral, a small patch of
coastal sage scrub, and non - native
ornamental vegetation originating
from the surrounding homes.
Typical chaparral species in this
area include toyon (Heteromeles
arbutifolia), laurel sumac (Malosma
laurina), and ceanothus ( Ceanothus
sp.) Non - native and ornamental
species include giant reed (Arundo
donax), acacia, eucalyptus,
myoporum, Mexican fan palm,
Brazilian pepper tree (Schinus terebinthifolius), Peruvian pepper tree (Schinus
molle), castor bean (Ricinus communis), tree tobacco (Nicotiana glauca), pampas
grass (Cortaderia sp.), and fennel (Foeniculum vulgare). The canyon bottom in this
area is dominated by riparian vegetation including willows (Salix spp.), blackberry
(Rubus sp.), cattail (Typha sp.), and bulrush (Scirpus sp.). A small freshwater
marsh comprised almost exclusively of cattail is situated at the mouth of the gully
adjoining Little Corona Beach.
The central section of the canyon immediately northeast of the Coast Highway,
while closely confined by residential development, contains fewer ornamental plant
species than the coastal portion and supports southern mixed chaparral and
southern willow scrub habitats with species compositions similar to the lower
canyon. The chaparral in this area supports toyon, laurel sumac, ceanothus,
chamise (Adenostoma fasciculatum), lemonadeberry (Rhus integrifolia), scrub oak
(Quercus berberidifolia), southern honeysuckle (Lonicera subspicata), redberry
(Rhamnus crocea), bush monkey flower (Mimulus aurantiacus), and sugar bush
(Rhus ovata).
Approximately adjacent to the intersection of 5th Avenue and Poppy Avenue, the
gully veers east and opens into a broader canyon. The southern slopes of the
canyon in this area support dense stands of southern mixed chaparral, while the
northern slopes support disturbed annual grassland, possibly established as
chaparral and coastal sage scrub, but subsequently cleared for fire prevention by
homeowners. At present, the annual grassland contains black mustard (Brassica
nigra), tocalote (Centaurea melitensis), artichoke thistle (Cynara cardunculus), wild
oats (Avena fatua), soft chess (Bromus hordeaceus), barley (Horedum sp.), ripgut
brome (Bromus diandrus), and fennel. Diegan coastal sage scrub becomes more
dominant as the canyon slopes on the upper portions of the canyon veer
eastward. This community is composed of California sagebrush (Artemisia

califomica), California buckwheat (Eriogonum fasciculatum), white sage (Salvia
apiana), prickly pear (Optunia sp.), coyote brush (Baccharis pilularis), blue
elderberry (Sambucus mexicana), laurel sumac, lemonadeberry, and California
bush sunflower (Encelia californica).
The canyon floor of Buck Gully supports a southern willow scrub community,
dominated by willows and mule fat (Baccharis salicifolia), with occasional western
sycamore (Platanus racemosa) and cottonwood (Popu /us fremontil). Associated
plant species include cattail, blue elderberry, poison oak (Toxicodendron
diversilobum), rush (Juncus spp.), and nutsedge (Cyperus sp.).
The upper canyon is broader than the lower canyon and is therefore less impacted
by adjacent development. Vegetation in this area is primarily Diegan coastal sage
scrub and southern mixed chaparral, interrupted by occasional patches of annual
grassland, and southern willow scrub associated with the creek at the canyon
bottom.
The lower (western) portion of Buck Gully is isolated from the upper Buck Gully by
the Coast Highway. This area is closely confined by residential development on
the south and north. The proximity to development, accessibility by local residents
and their pets, and abundance of non - native ornamental plant species detract from
the quality of habitat for wildlife species in this area. The upper (eastern) portion of
Buck Gully is a broad, open, relatively undisturbed canyon. Coastal sage scrub
and mixed chaparral dominate much of the area, except for the riparian corridor
along the canyon bottom and the tops of the canyon, which are influenced by the
adjacent residential development. Much of the native vegetation near the rim of
the canyon has been removed to reduce wildfire hazard.
Ornamental and non - native plant species from the adjacent residential
development have encroached into Buck Gully, especially in the lower, narrow
portions. Annual grasslands in Buck Gully consist of nonnative annual grasses and
(orbs. Some non - native inclusions were also observed in the Diegan coastal sage
scrub, southern mixed chaparral, and southern willow scrub habitats.
Potential impacts to the natural habitats in this study area include erosion,
contaminated urban runoff, increased human activity, ambient noise, invasive
species, and uncontrolled public access.
Studv Area No. 10: Mornina Canyon
Morning Canyon is oriented perpendicular to the coastline between Corona
Highlands and Cameo Highlands. The 11.2 -acre study area is bordered by the
Pacific Ocean to the west, Pelican Hills Golf Course to the east, and residential
development to the north and south of the site. Morning Canyon is under private
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -24
ownership.
Morning Canyon is characterized by
disturbed, remnant, southern mixed
chaparral vegetation on the canyon
floor and along the upland slopes.
This area, however, contains few
remaining native species and is
dominated by non - native and
ornamental species that have invaded
the canyon from adjacent residential
areas located immediately to the
northwest and southeast. Native plant
species in the remnant southern
mixed chaparral community include Morning Canyon near Pelican Bay GolfCoirse
coyote brush, toyon, mountain
mahogany (Cercopcarpus betuloides), lemonadeberry, and blue elderberry. Non-
native species include fennel, pampas grass, acacia, date palm (Phoenix sp.), fig
(Ficus sp.), hottentot fig (Carpobrotus edulis), Himalayan blackberry (Rubus
discolor), tree tobacco, pittosporum (Piosporum sp.), and castor bean.
The canyon bottom once supported a southern willow scrub and willows, mule fat,
and mugwort (Artemisia douglasiana) can still be observed growing among the
dominant non - native vegetation, though these species are no longer common
enough to consider this habitat to be southern willow scrub. Nonnative plant
species now dominate the bottom and lower slopes of the canyon and include
giant reed, acacia, hottentot fig, eucalyptus, myoporum, Mexican fan palm,
Brazilian pepper tree, Peruvian pepper tree, pampas grass, ivy (Hedera sp.), and
fennel.
Although most of the native riparian- associated species have been displaced by
non - native and ornamental species, the area is still used by riparian wildlife, such
as American crow (Corvus brachyrhyncus), northern mockingbird (Mimus
polyglottos), mourning dove (Zenaida macroura), cedar waxwing (Bombycilla
garrulous), English sparrow (Passer domesticus), raccoon (Procyon lotor), and
opossum (Didelphis virginiana). The presence of a perennial watercourse along
with a structurally diverse woody vegetation community provides the necessary
habitat attributes that are essential to riparian- associated species.
The lower, southwestern section of Morning Canyon is separated from the upper
section of Morning Canyon by the Coast Highway. The entire canyon is very
narrow and closely bordered by residential development on the northwest and
southeast, the Pacific Ocean to the southwest, and the Pelican Hills Golf Course
at the northeastern edge of the area. Ornamental species have completely
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -25
displaced native vegetation in much of canyon and now dominate throughout the
majority of this ESA. Pets from the adjacent residences likely use the area and
further discourage wildlife use of the canyon.
Potential impacts to the natural habitats in this study area include increased human
activity, ambient noise, invasive species, erosion, sedimentation, and uncontrolled
public access.
Study Area No. 11: Newport Beach Marine Conservation Area
The 85.8 -acre Newport Beach Marine
Conservation Area extends from
Little Corona Beach to Cameo
Shores Road. The refuge's coastline
length is 0.6 miles (mi). It extends a
distance of 200 feet (ft) offshore and
to depths of about 1Bft Mean Lower
Low Water (MLLW). This refuge is
significant because it is the first
section of rocky intertidal and rocky
subtidal habitat south of Point
Fermin, along with the Irvine Coast
Marine Conservation Area. While
Arch Rode in the Newport Beach Marine Conservation Area sections of the refuge are within high
visitor use areas (Little Corona Tide
Pools) and have exhibited declines in biodiversity related to public use as well as
natural processes, the downcoast section of the refuge in the vicinity of Cameo
Shores is relatively inaccessible and exhibits less human -use disturbances. The
beach is fronted by a sandstone bluff mixed with native coastal scrub and
introduced vegetation. Intertidal areas consist of platform intertidal reefs and
pocket sandy beaches, with conspicuous offshore rocks, stacks, and arches.
Subtidally, the seafloor is a mixture of sand bottom and reefs. The siltstone reefs
extend seaward of the limits of the refuge to depths of about 50 ft. Numerous
types of plants, invertebrates, fishes, and seabirds occur within the limits of the
refuge, and marine mammals (sea lions, bottlenose dolphin, and gray whales) will
occasionally pass through. Tide pools use at Little Corona is managed by the
City's tide pool ranger program, which includes docent -led tours of more than
3,000 students annually.
Runoff from the surrounding watershed and streets enter the refuge at several
points, the largest being Buck Gully, which drains across the sandy beach into the
refuge. This runoff consists of various pollutants, such as fecal material from pets,
oil and grease, fertilizers, and other urban -based pollutants. In addition, Buck
Gully runoff contributes to high- suspended sediment loads to the refuge,
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -26
particularly during years of high rainfall and runoff, which increases water turbidity
and reduces submarine light levels. Water quality in the refuge is also likely
influenced by the quality of the tidal waters flushed from Newport Bay on the
outgoing tides, which tend to move downcoast oriented longshore currents.
Heavy human use of the refuge has a major impact on the refuge's intertidal
marine resources, resulting from illegal collecting and trampling of intertidal plants
and invertebrates. Parry boats and commercial and sport fishing vessels, as well
as skin divers and scuba divers frequent the waters of the refuge for fishing and
collecting. Commercial lobster fishermen also utilize the nearshore reefs within
the refuge. These activities have a potential to reduce the productivity of the
nearshore fishery.
The Irvine Coast Marine Conservation Area will expand to include the Newport
Beach Marine Conservation Area and parts of the Laguna Beach Marine
Conservation Area, and will be named the Crystal Cove State Marine Reserve
under the Marine Life Protection Act (MLPA). The goal of the MLPA (Chapter
1015, Statutes of 1999) is to set up a system for evaluating and coordinating
Marine Protected Areas (MPAs) in the state. The MLPA states that "marine life
reserves" are essential elements of an MPA system because they "protect habitat
and ecosystems, conserve biological diversity, provide a sanctuary for fish and
other sea life, enhance recreational and educational opportunities, provide a
reference point against which scientists can measure changes elsewhere in the
marine environment, and may help rebuild depleted fisheries." The CDFG is
required to develop a comprehensive master plan that combines ecosystem
management with protection and public outreach for the state's MPAs, including
the Newport Beach Marine Conservation Area. Under state marine reserve status,
commercial and recreational fishing could be further restricted or prohibited to
protect marine resources.
Study Area No. 12: Castaways
The 23.3 -acre Castaways ESA is located east of Dover Drive and south of
Castaways Lane along Upper Newport Bay. A church and offices are located to
the north, residential developments are located immediately west and Lower
Castaways is located between the study area and the Coast Highway Bridge.
Several trails cross throughout the site and can be accessed via Castaways Lane.
The Castaways site is designated as a view park. The existing trail system
encourages and directs the public to locations where the views of the coast,
harbor and bay can be enjoyed with minimal impacts to the natural habitats.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -27
The Castaways site is characterized
by four plant communities: southern
willow scrub, Diegan coastal sage
scrub (a restoration area), southern
coastal bluff scrub, and non - native
grassland.
The center of the site is characterized
by non - native grassland, which
comprises the majority of the site.
Plant species associated with this
community include black mustard,
Russian thistle, and Bermuda grass
(Cynodon dactylon). Several dirt trails
and paved routes transect the parcel.
Coastal duff scrub at Castaways
A drainage runs north -to -south from the church parking lot parallel to Dover Drive.
This drainage is dominated by native plant species that are characteristic of
southern willow scrub communities including willows, mule fat, western sycamore,
cattail, and Mexican elderberry. A second ephemeral drainage runs east -to -west
from the hilltop near Dover Drive. This feature supports mainly upland and non-
native vegetation including Brazilian pepper tree, Peruvian pepper tree, acacia,
eucalyptus, myoporum, tree tobacco, and lemonadeberry.
The eastern portion of the site located along the east - facing slopes that overlook
the bay support southern coastal bluff scrub vegetation. Saltbush, tree lupine,
prickly pear, coyote brush, California buckwheat, and coastal goldenbush, and
California bush sunflower dominate the vegetative cover. The bluff area is fenced
and protected from direct disturbance. Bluff habitat within this study area is
continuous with the bluff habitat that stretches north to Polaris Drive.
A Diegan coastal sage scrub restoration area is located within the northwest
portion of the parcel, immediately east of the riparian area. Plant species
associated with this area include California sagebrush, coyote brush, California
buckwheat, black sage (Salvia mellifera), and coastal goldenbush.
The Diegan coastal sage scrub restoration area is the first phase of Castaways
Park Revegetation Project. The project will remove the non - native and ruderal
vegetation and replace it with new native vegetation to create a view park for
passive recreation and nature observation.
Potential impacts to the natural habitats in this study area include increased human
activity, ambient noise, invasive species, and uncontrolled public access.

Studv Area No.13: Newport Harbor Entrance Channel Kelp Beds
The giant kelp (Macrocystis
pyrifera) bed within the Newport
Harbor Entrance Channel is one of
the only giant kelp bed habitats
currently existing between Seal
Beach and South Orange County.
Giant kelp beds, once found
abundantly along the coastline
between Corona del Mar and
Laguna Beach are now extremely
sparse. Warming trends, El Nino
storm events, ecological
imbalances due to over fishing, and
Giant kelp bed habitat atNewportHarborEntrance extensive grading of lands around
drainages adjacent to kelp beds that increase suspended sediment loads to the
ocean are important contributors to the decline of kelp beds in southern California
and have likely resulted in the decline of kelp beds within the Newport Beach
Marine Conservation Area and the Irvine Coast Marine Conservation Area /Crystal
Cove State Park. Giant kelp currently is rare within these refuges. Giant kelp
reforestation is being attempted in Crystal Cove State Underwater Park. However,
it is still too early to evaluate the success of this project.
Occurring along nearly half of the length of the west jetty and extending from
depths of 10 to 30 feet, the Newport Harbor Entrance giant kelp bed, while
relatively small, has maintained itself over a period of several years while other
kelp beds along the Newport Beach and Laguna Beach have declined. Two
separate kelp beds are present. The largest bed is located along the outermost
half of the west jetty, while a second and smaller bed is located along inner third of
the west jetty. The total acreage of kelp is approximately 1. 16 acres. It is a
productive and viable resource and supports over 70 species of plants,
invertebrates, and fishes. During subtidal reconnaissance dives of underwater
habitats along the Newport coastline in 2002, the marine life associated with the
Newport Harbor Entrance Channel jetty quarry rock and within the kelp bed was
second only to the 200 Meter Reef, located in the Crystal Cove Underwater Park,
in species richness.
Dredging activity and jetty reconstruction projects have a potential to reduce the
viability of the kelp beds located within the Harbor Entrance Channel. Future
projects conducted within the Entrance Channel should include protection
measures to avoid long -term impacts to kelp bed resources.

4.1.4 Eelgrass Meadows
The flowering, marine vascular
plant "eelgrass" (Zostera
marina) is an important marine
resource due to its nursery
function for invertebrates and
fishes. Eelgrass forms
meadows on mudflats and
subtidal sediments in bays,
estuaries, and occasionally, in
offshore marine sand bottom
habitats. The meadows (and
sub units called "beds" and
"patchesl provide a habitat for
Eelgrass in the Grand Canal invertebrates as a source of food
and attachment, and for marine
fishes that seek the shelter of the beds for protection and forage on invertebrates
that colonize the eelgrass blades and sediments in and around eelgrass
vegetation.
Eelgrass can be found worldwide in quiet, temperate -water mud or sand habitats.
In Southern California, eelgrass can be found in coastal wetlands, bays, and
harbors at depths between +1 feet Mean Lower Low Water (MLLW) to about —25
feet MLLW and on nearshore coastal sand bottoms to depths of 50 to 80 feet
MLLW. The conditions favorable for the growth of this plant are periods of low
rainfall, runoff and sedimentation, good light penetration, optimum temperature
range (50 to 68 degrees Fahrenheit), moderate dissolved oxygen concentration,
limited algal growth and good water quality. Once established, eelgrass patches
can expand through vegetative growth along extended rhizomes to form vast
meadows.
At present (2003), eelgrass is abundant in several sections of Newport Harbor and
has been expanding its distribution in both Lower and Upper Newport Bay over the
last several years due to favorable growing conditions, lack of heavy rainfall,
minimal runoff, and more stringent water quality regulations. The lowest recorded
eelgrass coverage occurred in 1993 with less than 3 acres. A 2002 survey found
approximately 35 acres of eelgrass coverage. Its depth range in Newport Bay is
from 0.0 ft Mean Lower Low Water (MLLW) to —28 ft. On the average, however,
most eelgrass in the Bay grows to a depth of about —8 to —10 ft MLLW. It grows
deepest in the Newport Harbor Entrance Channel.
Eelgrass grows extensively within the Harbor Entrance Channel, where it covers
approximately 20 acres of underwater sandy bottom habitat. Other sections of
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -36
Newport Bay that currently support extensive eelgrass beds include the eastern
shoreline of the Bay between Carnation Cove to the Coast Guard Base, Balboa
Island (and in the Grand Canal), along the eastern end of the Balboa Peninsula,
around Harbor Island, within the Linda Isle Basin, and in the channels around its
perimeter. Eelgrass is currently expanding its distribution. Locations where
smaller beds have become established within the last few years include the
southern edge of the Bayshores development, a shoal immediately south of the
Coast Highway Bridge near the Swales Marina; Lido Isle, and on the north side of
Lido Reach between the Bayshores community west to the Balboa Bay Club.
July 2002 observations indicate eelgrass is recolonizing shallow subtidal habitat in
Upper Newport Bay between the Coast Highway Bridge and Dover Shores along
both sides of the Main Channel after a long -term absence.
Some of the eelgrass currently growing in Newport Harbor is the result of previous
eelgrass transplants conducted during dredging of the Entrance Channel in the
early 1980s, and in the Grand Canal on Balboa Island in 1999. These transplant
programs were conducted as mitigation for Newport Harbor projects that resulted
in the loss of eelgrass habitat. A large -scale eelgrass restoration program is
currently being planned for Newport Harbor by the U.S. Army Corps of Engineers,
the County of Orange, and the City of Newport Beach with the goal of enhancing
between 5 and 10 acres of eelgrass to the Harbor within eight I pilot project
restoration sites starting in May 2004. This will add a significant amount of
biological value to the Harbor. Once established, these restoration sites will be
enhanced by further plantings and serve as eelgrass mitigation sites for the loss of
eelgrass habitat for small harbor dredging projects (500 to 1000 cubic yards).
Dredging and dock and bulkhead construction projects have a potential to impact
eelgrass bed resources within several areas of Newport Bay through direct habitat
loss or secondary effects of turbidity or vessel anchor scarring. However, ongoing
maintenance of harbor structures and periodic dredging is essential to protect the
Newport Harbor's value as a commercial and recreational resource. A
comprehensive and balanced management plan is necessary in order to maintain
the recreational and commercial uses of the harbor while protecting its natural

4.1.4 -1. Continue to protect eelgrass meadows for their important ecological
function as a nursery and foraging habitat within the Newport Bay
ecosystem.
4.1.4 -2. Implement eelgrass restoration and enhancement programs in
Newport Harbor.
4.1.4 -3. Site and design boardwalks, docks, piers, and other structures that

extend over the water to avoid impacts to eelgrass meadows.
Encourage the use of materials that allow sunlight penetration and
the growth of eelgrass.
4.1.4 -4. Provide for the protection of eelgrass meadows and mitigation of
impacts to eelgrass meadows in a comprehensive harbor area
management plan for Newport Bay.
4.1.4 -5. Continue to require Caulerpa protocol surveys as a condition of City
approval for projects in Newport Bay and immediately notify the
SCCAT when found.
4.1.5 Coastal Foredunes
Dune habitats are identified by
stands of dense to sparse annual
and perennial herbs, grasses, or
shrubs occurring on sand dunes
along the coast. Dune habitat is
considered a sensitive plant
community and is listed as rare or
threatened or is otherwise protected
by the U.S. Fish and Wildlife
Service, California Department of
Fish and Game, California Coastal
Commission, or local agencies.
Loss of dune habitat as a result of
coastal development is considered
to be a significant environmental
impact, and any potential impacts to
this resource must be avoided, minimized, or compensated.
Southern coastal foredune habitat on the Balboa Peninsula
In Newport Beach, southern coastal foredune habitat extends southwest along the
ocean side of the Balboa Peninsula from 10th Street to the tip of the peninsula.
The vegetation in this community is generally sparse with overall cover ranging
from 20 to 70 percent in some areas, while other areas are completely devoid of
vegetation. Areas of open sand fragment this habitat. Dominant plant species
include non - native species such as purple sand - verbena (Abronia umbellata), sea
rocket (Cakile maritima), beach evening primrose (Camissonia cheiranthifolia),
sea -fig (Carpobrotus chiliensis), hottentot fig (Carpobrotus edulis), beach morning
glory (Calystegia soldanella), and beach bur (Ambrosia chamissonis).
Ornamental and non -native species, likely introduced from the adjacent
residences, dominate much of the southern coastal foredune habitat. Numerous
residences use the beach area as an extension of their backyards. Some
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -38
residents have planted and irrigated the ornamental species, which have replaced
native species in these areas. Increased human activity and uncontrolled public
access also adversely impact these dune habitats, as evidenced by the numerous
trails bisecting the dunes. Many areas are almost completely covered by sea -fig
and hottentot fig. If dune habitat losses cannot be avoided, then mitigation
programs to restore dune habitat within Newport Beach should be implemented.
Policies:
4.1.5 -1. Require the removal of exotic vegetation and the restoration of native
vegetation in dune habitat.
4.1.5 -2.
4.1.5 -3. Direct public access away from dune habitat areas through the use
of well - defined footpaths, boardwalks, protective fencing, signage,
and similar methods.
4.1.5 -4. Design and site recreation areas to avoid impacts to dune habitat
areas.
4.1.5 -5. Require a coastal development permit for earthmoving beach sand in
dune habitat areas.

4.2 Wetlands and Deepwater Areas
Coastal Act policies related to wetlands and deepwater areas that are relevant to Newport
Beach include the following:
30231. The bidogxucal productivity and the quality of coastal watery streams, wedards, estuaries, and lakes
Appropriate to maintain optimum poptiabons of morn organisms and for the protection of human health Mall be
maintained and, where feasible. restored through, among direr nests, minimizing adverse effects of waste water
discharges and entraimnem, controlling runoff, preventing depletion of ground water supplies and substantial
interference with surface waterflow, encouraging waste water redarnation, maintaining natural vegetation buffer areas
that protect riparian habitats, and minimizing Aeration of natral streams.
The Coastal Act distinguishes wetlands from other types of water areas, such as
estuaries and open coastal waters. Section 30121 of the Coastal Act defines
"wetlands" as 'lands within the coastal zone which may be covered periodically or
permanently with shallow water and include saltwater marshes, freshwater
marshes, open or closed brackish water marshes, swamps, mudflats, and fens."
Therefore, the interpretation of the term "shallow water" can be used to distinguish
wetlands from other submerged areas. The U.S. Fish and Wildlife Service defines
the boundary between wetland and deepwater habitat as the elevation of extreme
low -water of spring tide for areas subject to tidal influence. Therefore, for
purposes of the Coastal Act, wetlands can be interpreted as beginning at extreme
low -water of spring tide and "estuary" or 'open coastal water" is anything deeper.
4.2.1 Southern California Wetlands
Wetlands are transitional lands between terrestrial and aquatic systems where the
water table is usually at or near the surface or the land is often covered by shallow
water during some parts of the year. Wetlands can be categorized according to
specific habitat and type of vegetation. In Southern California, wetlands generally
fall into four categories: estuarine wetlands, such as the Upper Newport Bay and
Semeniuk Slough; freshwater marshes, which can be found in Big Canyon, Buck
Gully, and San Diego Creek; riparian wetlands, which occur along creeks and
streams or bodies of water; and vernal pools, which can be found on Banning
Ranch.
Southern California coastal wetlands and watersheds have been dramatically
altered or destroyed by human activities over the past 150 years. Wetlands have
been filled and rivers, streams, and creeks have been rerouted, dammed,
channelized, and paved. Estimates of historic wetland acreages compiled from
the literature and U.S. Coast and Geodetic Surrey maps created between 1851
and 1893 indicate a loss of 70 percent reduction in coastal wetlands in Southern
California.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -40
Wetlands are recognized as very important ecosystems with the following multiple
values and functions:
• Biological Diversity. Wetlands provide important habitat for diverse
communities of plants and animals, including federally listed threatened or
endangered species.
• Waterfowl Habitat. Wetlands provide the principal habitat for migratory
waterfowl. California provides critical wintering habitat for millions of
waterfowl migrating along the Pacific Flyway, which extends from Canada
to Mexico.
• Fisheries. Wetlands provide direct spawning and rearing habitats and food
supply that supports both freshwater and marine fisheries.
• Flood Control. Wetlands detain flood flows, reducing the size and
destructiveness of floods.
• Water Quality. Wetlands absorb and filter pollutants that could otherwise
degrade ground water or the water quality of rivers, lakes, and estuaries.
• Ground Water Recharge. Some wetlands recharge aquifers that provide
urban and agricultural water supplies.
• Recreation. Wetlands support a multi - million - dollar fishing, hunting, and
outdoor recreation industry nationwide.
The Coastal Act requires the projection of wetlands. Development or alteration of
coastal wetlands is primarily regulated by Section 30233 of the Coastal Act, which
provides that the diking, filling, or dredging of open coastal waters, wetlands, or
estuaries may only be permitted where there is no less environmentally damaging
alternative and must be restricted to a narrow range of allowable uses. The
Coastal Act also requires the protection of biological productivity and quality of
coastal waters, streams, wetlands, estuaries, and lakes. Water quality issues are
discussed in detail in Section 4.3 (Water Quality).
Two federal statutes provide the primary regulatory authority over wetlands. The
Clean Water Act (Section 404(b)) regulates disposal of dredge and fill materials
into waters of the United States, including all streams to their headwaters, lakes
over 10 acres, and contiguous wetlands, including those above the ordinary high
water mark in non -tidal waters and mean high tide in tidal waters. The River and
Harbors Act of 1899 (Section 10) regulates the diking, filling, and placement of
structures in navigable waterways. The U.S. Army Corps of Engineers is primarily
responsible for the implementation and enforcement of rules and regulations
pertaining to both sections of these statutes. The Environmental Protection
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -41
Agency, the Natural Resources Conservation Service, the National Marine
Fisheries Service (NMFS), and the Fish and Wildlife Service (FWS) review
applications for Section 404 permits and can provide the Corps with comments
and recommendations reflecting agency concerns.
Policies:
4.2.1 -1. Recognize and protect wetlands for their commercial, recreational,
water quality, and habitat value.
4.2.1 -2. Protect, maintain and, where feasible, restore the biological
productivity and the quality of coastal waters, streams, wetlands,
estuaries, and lakes.
4.2.2 Wetland Definition and Delineation
Due to semi -arid Mediterranean climate of Southern California, some wetlands can
remain dry for one or more seasons. This presents problems for the identification
and delineation of wetlands. Section 30121 of the Coastal Act defines "wetlands"
as 'lands within the coastal zone which may be covered periodically or
permanently with shallow water and include saltwater marshes, freshwater
marshes, open or closed brackish water marshes, swamps, mudflats, and fens."
However, a more specific definition is provided in Section 13577 (b -1) of the
California Code of Regulations:
"...land where the water table is at near, or above the land surface long enough
to promote the formation of hydric soils or to support the growth of hydrophytes,
and shall also include types of wetlands where vegetation is lacking and soil is
poorly developed or absent as a result of frequent drastic fluctuations of surface
water levels, wave action, water flow, turbidity or high concentration of salts or
other substances in the substrate. Such wetlands can be recognized by the
presence of surface water or saturated substrate at some during each year and
their location within, or adjacent to vegetated wetland or deepwater habitats."
The boundary line between the wetland and adjacent upland area is determined
by the extent of one or more key wetland characteristics: hydrology (frequency,
duration, and timing of inundation or saturation), hydric soils (soil with
characteristics resulting from prolonged saturation), and hydrophytic vegetation
(plants adapted to life in water, or in periodically flooded and /or saturated
anaerobic soils). Positive wetland indicators of all three characteristics are
normally present in wetlands. However, the presence of only one of these
characteristics (e.g., hydrology, hydric soils, or hydrophytic vegetation) is needed
for an area to qualify as a wetland, pursuant to the California Code of Regulations.
Hydrology is the key characteristic because it drives the formation of hydric soils
and allows hydrophytic vegetation to establish dominance. However, hydrology is
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -42
the most difficult of the three wetland characteristics to quantify. Many of the
hydrology indicators are subjective and often it is difficult to determine the timing
and duration of hydrology without visual observation. Therefore, the Coastal
Commission considers a predominance of hydrophytes or a predominance of
hydric soils as evidence that the land was "wet enough long enough" to develop
wetland characteristics.
Although vegetation is often the most readily observed parameter, sole reliance on
vegetation or either of the other parameters as the determinant of wetlands can
sometimes be misleading. Many plant species can grow successfully in both
wetlands and non - wetlands, and hydrophytic vegetation and hydric soils may
persist for decades following alteration of hydrology that will render an area a non -
wetland. In situations where ambiguities in wetland characteristics exist, the
judgment of a qualified biologist may be required to determine whether an area
meets the definition of a wetland. The presence or absence of more than one
parameter may be considered along with other factors, such as recent
precipitation patterns, topography, drainage patterns, and adjacency to identified
wetlands.
Policies:
4.2.2 -1. Define wetlands as areas where the water table is at, near, or above
the land surface long enough to bring about the formation of hydric
soils or to support the growth of hydrophytes. Such wetlands can
include areas where vegetation is lacking and soil is poorly
developed or absent as a result of frequent drastic fluctuations of
surface water levels, wave action, water flow, turbidity or high
concentration of salts or other substances in the substrate.
Wetlands do not include areas which in normal rainfall years are
permanently submerged (streams, lakes, ponds and impoundments),
nor marine or estuarine areas below extreme low water of spring
tides, nor vernally wet areas where the soils are not hydric.
4.2.2 -2. Where ambiguities in wetland characteristics exist, the presence or
absence of more than one wetland parameter may be considered
along with other factors, including recent precipitation patterns,
topography, drainage patterns, and adjacency to identified wetlands,
to determine whether an area meets the definition of a wetland and
to delineate wetland boundaries.
4.2.2 -3. Require a surrey and analysis with the delineation of all wetland
areas when the initial site surrey indicates the presence or potential
for wetland species or indicators. Wetland delineations will be
conducted in accordance with the definitions of wetland boundaries
contained in section 13577(b) of the California Code of Regulations.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -43
4.2.2 -4. Require buffer areas around wetlands of a sufficient size to ensure
the biological integrity and preservation of the wetland.
4.2.3 Dredging, Diking, and Filling
Coastal Act policies related to dredging, diking, or filling that are relevant to Newport

Upper Newport Bav
Newport Bay is an estuary, an embayment along the coast where inland fresh
water mixes with salt water from the ocean. Newport Bay's main source of fresh
water is San Diego Creek. Historically only about 15 square miles of land drained
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -44
into the bay via San Diego Creek.
However, San Diego Creek was
channelized in 1968 so that peak
floods and sediment could be
efficiently routed to the bay. This
increased the drainage area to about
118 square miles. In 1969, heavy
storm runoff poured hundreds of
thousands of tons of sediment into
the bay. Subsequent storm season
sedimentation events in 1978 and
1980 caused shallowing of the Upper
Bay. Intertidal saltmarsh vegetation
became established and expanded
rapidly. This would have eventually
filled the bay with sediment and
turned it into a meadow.
San Diego Creek near Back Bay Drive
In 1985, 85 acres of the Upper Bay were dredged out to create the Unit I Sediment
Control Basin (depths —3 to —7 feet MSL). A second dredging project in 1988
created the 37 -acre Unit 11 Sediment Control Basin, just south of the Main Dike
(depth —14 feet MSL). Both basins have worked well, collecting large volumes of
coarser grained sediment from periodic flood runoff, principally down San Diego
Creek. However, these require extensive on -going maintenance dredging. The
last major dredging activity in the bay occurred in 1998 -99. This project cleared
about 900,000 cubic yards of sediment from the bay. As the 1998 -99 project was
completed, Newport Beach, Orange County, the Irvine Ranch Water District, the
Santa Ana Regional Water Quality Control Board, The Irvine Company, the
California Department of Fish and Game, and the watershed cities of Irvine, Costa
Mesa, Tustin, Lake Forest, and Laguna Woods, began planning a larger, more
significant project with the U.S. Army Corps of Engineers to complete the
restoration of the Upper Newport Bay.
The Upper Newport Bay Ecosystem Restoration Project was developed to restore
and maintain tidal movement in the bay. The project would dredge more than 2.7
million cubic yards from the Upper Bay, restore deteriorated habitat, increase blue -
water views, move the Least Tern islands, and open up several island channels in
mid -Upper Bay.

Lower Newport Bay /Harbor
Since Lower Newport Bay was
dredged between 1934 and 1936 to
create the navigation channels, the
U.S. Army Corps of Engineers has
dredged the Lower Bay on only three
occasions. In 1941 they deepened
the turning basin at the west end of
the harbor (Lido Village area). In
1981, 85,000 cubic yards of sand
were dredged from the harbor
entrance adjacent to Big Corona. In
1998, 204,000 cubic meters of
sediment are removed from just
The Turning Basin below the Pacific Coast Highway
Bridge at the junction of the Main
and Upper Bay Channels in the area
of Harbor and Linda Islands. Except for these three projects, maintenance
dredging by the Corps to maintain the federally authorized harbor channels has
not been undertaken. As part of their maintenance responsibility, the Corps does
annual Newport Bay condition surveys of the navigational channels to ascertain
whether the channels are at or near their design depth and whether additional
dredging is necessary.
There are approximately 1,200 harbor permits for both residential and commercial
docks within Newport Harbor. It is general policy that the responsibility for
dredging around and under private docks rests with the private property owner. In
the past, the City has secured a Regional General Permit in order to expedite
property owners' permit processing with the Corps and the California Coastal
Commission. The Regional General Permits' term is typically 5 to 10 years.
Policies:
4.2.3 -1. Permit the diking, filling, or dredging of open coastal waters,
wetlands, estuaries, and lakes in accordance with other applicable
provisions of the LCP, where there is no feasible less
environmentally damaging alternative, and where feasible mitigation
measures have been provided to minimize adverse environmental
effects and limited to the following:
A. Construction or expansion of port/marine facilities.
B. Construction or expansion of coastal- dependent industrial

facilities, including commercial fishing facilities, haul -out boat
yards, and commercial ferry facilities.
C. In wetland areas only, entrance channels for new or expanded
boating facilities; and in a degraded wetland, identified by the
Department of Fish and Game pursuant to subdivision (b) of
Section 30411, for boating facilities if, in conjunction with such
boating facilities, a substantial portion of the degraded
wetland is restored and maintained as a biologically
productive wetland. The size of the wetland area used for
boating facilities, including berthing space, turning basins,
necessary navigation channels, and any necessary support
service facilities shall not exceed 25 percent of the degraded
wetland.
D. In open coastal waters, other than wetlands, including
estuaries, new or expanded boating facilities, including slips,
access ramps, piers, marinas, recreational boating, launching
ramps, haul -out boat yards, and pleasure ferries, and the
placement of structural pilings for public recreational piers that
provide public access and recreational opportunities.
E. Maintenance of existing and restoration of previously dredged
depths in navigational channels, turning basins, vessel
berthing, anchorage, and mooring areas, and boat launching
ramps. The most recently updated U.S. Army Corps of
Engineers maps shall be used to establish existing Newport
Bay depths.
F. Incidental public service purposes which temporarily impact
the resources of the area, such as burying cables and pipes,
inspection of piers, and maintenance of existing intake and
outfall lines.
G. Sand extraction for restoring beaches, except in
environmentally sensitive areas.
H. Restoration purposes.
I. Nature study, aquaculture, or similar resource - dependent
activities.
J. In the Upper Newport Bay Marine Park, permit dredging,

4.2.3 -2. Continue support of the Upper Newport Bay Ecosystem Restoration
Project to restore the Upper Newport Bay to its optimal ecosystem.
4.2.3 -3. Secure federal funding for the Upper Newport Bay Ecosystem
Restoration Project.
4.2.3 -4. Secure permanent use designation for the LA -3 sediment disposal
site for future dredging projects.
4.2.3 -5. Require the following mitigation measures for dredging projects in
the Upper Newport Bay Marine Park:
A. Dredging and spoils disposal must be planned and carried out
to limit turbidity and to avoid significant disruption to marine
and wildlife habitats and water circulation.
B. Maintenance dredging shall be encouraged where the
dredging enhances commercial or recreational use of the Bay.
When dredged material is of an appropriate grain size and
grain percentage, this material may be used to restore or
replace natural sandy sloping beaches in order to retain the
current profiles of Newport Bay. Maintenance dredging
activity shall have the approval of the U.S. Army Corps of
Engineers and shall meet applicable U.S. Environmental
Protection Agency standards.
C. Dredged material not suitable for beach nourishment shall be
disposed of offshore at a designated U.S. Environmental
Protection Agency disposal site.
D. Temporary dewatering of dredged spoils may be authorized
within the Bay's drainage if adequate erosion controls are
provided and the spoils are removed. A bond or a contractual
arrangement shall be a precondition to dredging of the
material, and final disposal of the dewatered material on the
approved dump site shall be accomplished within the time
period specified in the permit.
E. Dredged spoils shall not be used to fill riparian areas,
wetlands, or natural canyons.
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -48
F. Other mitigation measures may include opening areas to tidal
action, removing dikes, improving tidal flushing, restoring salt
marsh or eelgrass vegetation, or other restoration measures.
G. Dredge spoils suitable for beach nourishment should be
transported for such purposes to appropriate beaches or into
suitable longshore current systems provided that the
placement is permitted by a Section 404 permit.
4.2.3 -6. Continue to cooperate with the U.S. Army Corps of Engineers in their
maintenance and delineation of federal navigational channels at
Newport Harbor in the interest in providing navigation and safety.
4.2.3 -7. Continue to secure Regional General Permits through the U.S. Army
Corps of Engineers and the California Coastal Commission to
expedite permit processing for residential and commercial dock
owners in the Bay.
4.2.3 -8. Issue permits authorizing maintenance dredging under and around
residential piers and floats subject to compliance with all conditions
to the current Regional General Permit, including grain size
requirements, availability of suitable dredge disposal site, and
periodic bioassays.
4.2.3 -9. Require the following minimum mitigation measures if a project
involves diking or filling of a wetland:
A. If an appropriate restoration site is available, the applicant
shall submit a detailed restoration plan which includes
provisions for purchase and restoration of an equivalent area
of equal or greater biological productivity and dedication of the
land to a public agency or otherwise permanently restricts its
use for open space purposes. The site shall be purchased
before the dike or fill development may proceed.
B. The applicant may, in some cases, be permitted to open
equivalent areas to tidal action or provide other sources of
surface water. This method of mitigation would be
appropriate if the applicant already owned filled, diked areas
which themselves were not environmentally sensitive habitat
areas but would become so, if such areas were opened to
tidal action or provided with other sources of surface water.
C. However, if no appropriate sites under options (A) and (B) are
available, the applicant shall pay an in -lieu fee of sufficient
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -49
value to an appropriate public agency for the purchase and
restoration of an area of equivalent productive value, or
equivalent surface area.
This third option would be allowed only if the applicant is unable to
find a willing seller of a potential restoration site. The public agency
may also face difficulties in acquiring appropriate sites even though it
has the ability to condemn property. Thus, the in -lieu fee shall reflect
the additional costs of acquisition, including litigation, as well as the
cost of restoration. If the public agency's restoration project is not
already approved by the City, the public agency may need to be a
co- applicant for a permit to provide adequate assurance that
conditions can be imposed to assure that the purchase of the
mitigation site shall occur prior to issuance of the permit. In addition,
such restoration must occur in the same general region (e.g., within
the same estuary) where the fill occurred.
4.2.3 -10. All preferred restoration programs would remove fill from a formerly
productive wetland or estuary that is now biologically unproductive
dry land and would establish a tidal prism necessary to assure
adequate flushing. Since restoration projects necessarily involve
many uncertainties, restoration should precede the diking or filling
project. At a minimum, permits will be conditioned to assure that
restoration will occur simultaneously with project construction.
Restoration and management plans shall be submitted with the
permit application.
4.2.3 -11. Require that any project that includes diking, filling or dredging of a
wetland or estuary must maintain the functional capacity of the
wetland or estuary. Functional capacity means the ability of the
wetland or estuary to be self- sustaining and to maintain natural
species diversity. In order to establish that the functional capacity is
being maintained, the applicant must demonstrate all of the
following:
A. That the project does not alter presently occurring plant and
animal populations in the ecosystem in a manner that would
impair the long -term stability of the ecosystem; i.e., natural
species diversity, abundance, and composition are essentially
unchanged as a result of the project.
B. That the project does not harm or destroy a species or habitat
that is rare or endangered.
C. That the project does not harm a species or habitat that is
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -50
essential to the natural biological functioning of the wetland or
estuary.
D. That the project does not significantly reduce consumptive
(e.g., fishing, aquaculture and hunting) or non - consumptive
(e.g., water quality and research opportunity) values of the
wetland or estuarine ecosystem.
4.2.3 -12. Require that new developments on the waterfront to design and site
docking facilities in relationship to the usable water area.
4.2.3 -13. Design and site all structures permitted to encroach into open
coastal waters, wetlands, and estuaries to harmonize with the natural
appearance of the surrounding area.
4.2.3 -14. Continue to limit residential and commercial structures permitted to
encroach beyond the bulkhead line to piers and docks used
exclusively for berthing of vessels. However, this policy shall not be
construed to allow development that requires the filling of open
coastal waters, wetlands or estuaries that would require mitigation
for the loss of valuable habitat in order to place structures closer to
the bulkhead line or create usable land areas.
4.2.3 -15. Require restoration plans to be reviewed and approved by a qualified
professional prior to accepting sites for mitigation.

4.2.4 Dredge Spoils Disposal
Coastal Act policies related to dredge spoils disposal that are relevant to Newport Beach
include the following:
30233. (b) Dredging and spoils disposal shall be panned and tamed out to avoid significant disruption to marine and
wildlife habitats and water armilatinn. Dredge spoils suitable for beach replenishment should be transported for such
puposes to appropriate beaches or Into stitable lorgshere carat systems.
(d) Erosion control and flood control facilities consbucted an watercouses can impede the movemat of sediment
and nurients which would otherwise be carded by storm runoff into coastal waters. To facilitate the condntred delivery
Of these sediments to the I toral zone. whenever feasible, the ntaewial removed from these facilities may be placed at
appropriate points on the shorine in accordance with odw applicable provisions of this division, where feasible
mitigation measures have been provided to n inimize adverse environmental effects. Aspects that shall be considered
before isstdng a coastal development permit for such puposes are the method of placement, time of year of
placement, and senstivty of the placement area.
Section 30233(b) of the Coastal
Act requires that dredge spoils be
disposed of in a manner that
avoids disruption to habitats. The
selection of a disposal site for
dredged sediments is dependent
upon the physical and chemical
characteristics of the material.
Material free of chemical
contamination and consisting
primarily of sand of an acceptable
grain size (usually approximately
80 percent sand) is generally
suitable for beach nourishment and
placed on appropriate beaches or
within suitable longshore currents.
Material of appropriate grain size Dredging project in Balboa Island Channel
and with minimal contamination may be disposed of at unconfined, openwater
disposal sites authorized by the U.S. Environmental Protection Agency (EPA) and
U.S. Army Corps of Engineers. Dredged material that is physically suitable, but is
chemically unsuitable for aquatic disposal due to of elevated levels of certain
contaminants, may be used as fill, or in certain wetland construction and habitat
improvement projects, provided the contaminated materials are confined (e.g.,
parking lots, container piers, etc.).
Periodic maintenance dredging and habitat restoration projects in Newport Bay
require an environmentally acceptable disposal site. However, due to grain size
incompatibility, most of this material will not be suitable for beach nourishment.
Upland disposal is generally cost - prohibitive and harbor landfill and habitat
improvement projects occur too infrequently to be a reliable disposal option.
CITY COUNCIL DRAFT 1 Local Coastal Program

Therefore, the most practical
solution is a nearby offshore
disposal site. The LA -3 Ocean
Dredged Material Disposal Site
( ODMDS) is located approximately
4 miles off the coast of Newport
Beach. The LA -3 site has been
historically used for the disposal of
dredged material from Newport Bay
and for material not suitable for
beach nourishment at Newport
Beach due to grain size
incompatibility. The LA -3 ODMDS
was designated as an interim site
for the disposal of dredged material
Disposal of dredge material off of West Newport by the EPA. Securing LA -3 O DMS
as a permanently designated disposal site is therefore essential to the projection
of Newport Bay as a commercial, recreational and ecological resource.
Monitoring dredging projects within the region can provide opportunities to reduce
• disposal costs and utilize dredge spoils for beach nourishment. By placing the
sediment on the beach, offshore disposal costs are eliminated and the
nourishment project provides a tangible benefit from the dredging operation. In
1992, a nourishment project was devised to reduce disposal costs and to take
• advantage of the large quantities of beach -grade sand from the Lower Santa Ana
River Flood Control Channel Expansion Project. Nearly 1.3 million cubic yards of
dredged material were deposited offshore of Newport Beach, which migrated to
West Newport beaches under the influence of waves and currents.
Policies:
4.2.4 -1. Cooperate with the U.S. Environmental Protection Agency and the
U.S. Army Corps of Engineers to secure LA -3 ODMDS as a
permanently designated disposal site.
4.2.4 -2. Monitor dredging projects within the region to identify opportunities to
reduce disposal costs and utilize dredge spoils for beach
nourishment.
4.2.4 -3. Participate in regional sediment management by maintaining records
of the number of channelized streams, miles of channelization in
streams, volumes of sediment extracted from stream channels and
debris basins, and the grain size distribution of the extracted
sediments.

4.2.5 Eelgrass Protection and Restoration
Eelgrass (Zostera marina) is an
important underwater plant that is
indicative of and supports a
healthy and diverse marine
environment (see Section 4.1.4 -
Eelgrass Meadows). Dredging
projects in the Lower Bay have
the potential to impact eelgrass
bed resources. The loss of
eelgrass as a
development is
a significant
result of coastal

impact, and any potential impacts
to this resource must be avoided,
minimized,
Or mltlgated. Eelgrass in Newport Harbor Entrance Channel
Currently, mitigation requires an
expensive and time - consuming procedure that requires the eelgrass to be
replanted, monitored, and maintained per the Southern Calithmia Eelgrass
Mitigation Policy. This policy was developed in 1991 by the National Marine
Fisheries Service, U.S. Fish and Wildlife Service, and the California Department of
Fish and Game in order to standardize and maintain a consistent policy regarding
mitigating adverse impacts to eelgrass resources. The policy typically requires
that for every square foot of eelgrass removed, 1.2 square feet must be planted
and maintained. Eelgrass period of 5 years
for most projects.
mitigation monitoring
is required for a
The City, the County of Orange, and the U.S. Army Corps of Engineers have
worked with various resource agencies (including the U.S. Fish and Wildlife
Service, the National Marine Fisheries Service, and the California Department of
Fish and Game) to develop a plan whereby the City and the County of Orange
would establish, monitor, and maintain eelgrass beds. The eelgrass restoration
program is intended to enhance between 5 and 10 acres of eelgrass to the Harbor
within eight pilot restoration sites. Once deemed successful, these eight sites will
serve as eelgrass mitigation sites for City projects and as a mitigation bank from
which eelgrass mitigation credits will be issued to private property owners for
eelgrass removal resulting from dock and channel dredging projects.
The Southern Calithmia Eelgrass Mitigation Policy provides detailed procedures
for mitigating adverse impacts to eelgrass resources. However, the policy
contains no provision for post- recovery conditions. The policy was drafted at a
time when eelgrass coverage was near a low point in Newport Harbor. At present
(2003), eelgrass is abundant in several sections of Newport Harbor and has been
expanding its distribution in both Lower and Upper Newport Bay. The policy
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -54
requires all eelgrass patches to be protected or replaced, regardless of its size,
location, or habitat value or the extent of eelgrass coverage within the harbor.
Eelgrass protection, mitigation, and monitoring complicate and substantially
increase the cost of dredging maintenance projects, which are essential to
protecting the Newport Harbor's value as a commercial and recreational resource.
An eelgrass acreage baseline for
Newport Harbor is needed. The
baseline would be the minimum
acreage, based on the distribution,
density, and productivity, necessary
for eelgrass meadows to fulfill their
ecological function. Once the
baseline is determined, projects
may be granted exemptions to the
Southern California Eelgrass
Mitigation Policy mitigation
requirements, provided the eelgrass
acreage baseline is maintained.
The National Marine Fisheries
Newport Channel Service, as the lead agency, would
need to incorporate such a
provision into Southern Califomia Eelgrass Mitigation Policy and the U.S. Army
Corps of Engineers, the Coastal Commission, and the Santa Ana Regional Water
Quality Control Board to incorporate the provision into the City's Regional General
Permit and into any individual property owner's dredging or dock construction
permit that qualifies under future applications. The establishment of a baseline for
eelgrass meadows will serve to protect their important ecological function while
allowing the periodic dredging that is essential to protect the Newport Harbor's
value as a commercial and recreational resource.
Policies:
4.2.5 -1. Avoid impacts to eelgrass (Zostera marina) to the greatest extent
possible. Mitigate losses of eelgrass at a 1.2 to 1 mitigation ratio and
in accordance with the Southem Califomia Eelgrass Mitigation
Policy. Encourage the restoration of eelgrass throughout Newport
Harbor where feasible.
4.2.5 -2. When eelgrass planted in a mitigation area migrates into adjacent
areas that did not previously contain eelgrass, further mitigation for
dredging those adjacent areas shall not be required.
4.2.5 -3. Continue to cooperate with the County of Orange, the U.S. Army
Corps of Engineers, and resource agencies to establish eelgrass

restoration sites.
4.2.5 -4. Allow successful eelgrass restoration sites to serve as mitigation
sites for City projects and as a mitigation bank from which eelgrass
mitigation credits will be issued to private property owners for
eelgrass removal resulting from dock and channel dredging projects.
4.2.5 -5. Conduct studies to establish an eelgrass acreage baseline for
Newport Harbor based on the distribution, density, and productivity,
necessary for eelgrass meadows to fulfill their ecological function.
4.2.5 -6. Cooperate with the National Marine Fisheries Service to incorporate
a provision into the Southem California Eelgrass Mitigation Policy
that would allow exemptions to mitigation requirements for harbor
maintenance projects for provided the eelgrass acreage baseline is
maintained.
4.2.5 -7. Cooperate with the U.S. Army Corps of Engineers, the Coastal
Commission, and the Santa Ana Regional Water Quality Control
Board to incorporate the eelgrass acreage baseline exemption
provision into the City's Regional General Permit and into any
individual property owner's dredging or dock construction permit that
qualifies under future applications.
4.2.5 -8. Perform periodic surveys of the distribution of eelgrass in Newport
Bay in cooperation with the National Marine Fisheries Services to
insure that the eelgrass baseline is maintained.
4.2.5 -9. Cooperate with resource agencies to conduct a comprehensive
evaluation of biological, recreational, commercial and aquatic
resources of Newport Harbor and to develop a Harbor Area
Management Plan (RAMP) that will maintain all of the intended
beneficial uses of the harbor.

4.3 Water Quality
Coastal Act policies related to water quality that are relevant to Newport Beach include the
following:
30230. Marine resources shall be maintained. enhanced, and. where feasible, restored. Special protection shall be
given to areas and species of special biological or economic significance. Uses of the marine environment shall be
carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy

that protect riparian habitats, and minirrizatg alteration of natural streams.
30232. Protection against the spillage of crude od, gas, petroleum products, or hazardous substances shall be
provided in relation to any development or transportation of such materials. Effective containment and cleanup
facilities and procedures shall be provided for accidental spills that do occur
Newport Beach's greatest resources are
its coastline and bay. They have drawn
people here since prehistoric times, were
the preeminent factor in the community's
founding and development, and continue
to provide the community with
employment, recreation, natural habitat,
and a beautiful physical setting. With
these great gifts come great
responsibilities for the protection and
enhancement of these resources.
Newport Beach has traditionally cared
greatly about the quality of the water in Shoretne near Balboa Pier
Newport Bay and along the ocean
shoreline and has embarked on a number of programs to improve the water
quality.
4.3.1 TMDLs
Newport Bay receives urban runoff from the Newport Bay watershed, an area that
includes unincorporated County territory and areas within the cities of Costa Mesa,
Laguna Woods, Lake Forest, Irvine, Newport Beach, Orange, Santa Ana, and
Tustin. The primary tributaries to Newport Bay are the Santa Ana /Delhi Channel
(draining the cities of Costa Mesa and Santa Ana), San Diego Creek (draining the
cities of Irvine, Laguna Woods, Lake Forest, portions of Newport Beach, Orange,
and Tustin), and Big Canyon Creek (draining Newport Beach).
CITY COUNCIL DRAFT 1 Local Coastal Program

Newport Bay is designated as "water quality- limited" for four impairments under
the Federal Clean Water Act's Section 303(d) List, meaning that it is "not
reasonably expected to attain or maintain water quality standards" due to these
impairments without additional regulation. As a water quality- limited body, the
California Regional Water Quality Control Board, Santa Ana Region ( "Regional
Board ") and the U.S. Environmental Protection Agency ( "U.S. EPA ") have
developed total maximum daily loads ( "TMDLs ") for the following substances:
sediment, nutrients, fecal coliform, and toxic pollutants. The Board included these
TMDLs in the Regional Board's Basin Plan for the region.
Sediment. Adopted on October 9, 1998, the Sediment TMDL requires local
partners (stakeholders in the watershed) to survey the Bay regularly and to reduce
annual sediment coming into the Bay from 250,000 cubic yards to 125,000 cubic
yards (a 50% reduction) by 2008. The TMDL's goal is to reduce dredging
frequency in Upper Newport Bay to once every 20 years. Part of the TMDL
includes a proposed Upper Newport Bay Ecosystem Restoration Project, a U.S.
Army Corps of Engineers -led ecosystem restoration project that attempts to
restore the Upper Bay to its optimal habitat.
Nutrients. Approved by U.S. EPA on April 16, 1999, the Nutrient TMDL limits
nitrogen and phosphorus inputs to the Bay. The Nutrient TMDL attempts to
reduce the annual loading of nitrogen by 50% -- from 1,400 pounds per day today
to approximately 850 to 802 pounds per day at San Diego Creek — by 2012.
Phosphorus loading must fall from 86,912 pounds per year in 2002 to 62,080
pounds by 2007.
Fecal Coliform. Approved in December 1999, the Fecal Coliform TMDL attempts
to reduce the amount of fecal coliform inputs to the Bay enough to make the Bay
meet water contact recreation (REC1) standards (swimming, wading, surfing) by
2014 and shellfish harvesting (SHEL) standards (where waters support shellfish
acceptable for human consumption) by 2020.
Toxic Pollutants. Adopted by U.S. EPA on June 14, 2002, the Toxic Pollutants
TMDL addresses Bay inputs like heavy metals (chromium, copper, lead, cadmium,
zinc) and priority organics like (endosulfan, DDT, Chlordane, PCBs, Toxaphene,
diazinon, chlorpyriphos, more). It may lead to the reduction or elimination of
pesticide use by residents, businesses, and municipal services in the watershed.
Some controls will be placed on heavy metals. The Toxic Pollutants TMDL also
addresses existing toxic deposits in sediments in Rhine Channel and other areas
in the Lower Bay.
To implement the obligations of the TMDLs and to partner on related water quality
issues, Newport Beach, the Regional Board, the California Department of Fish and
Game, the County of Orange, and the other cities in the Newport Bay watershed
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -58
have established the Newport Bay Watershed Executive Committee as advised by
the Watershed Management Committee (WEC and WMC).
The WMC typically meets quarterly to comply with the TMDLs established by the
Regional Board. Generally, all the TMDLs established by the Regional Board
require that watershed- based solutions be developed by the watershed
stakeholders, and then the stakeholders jointly fund and implement these projects
throughout the watershed.
Policies:
4.3.1 -1. Continue to develop and implement the TMDLs established by the
Regional Board and guided by the Newport Bay Watershed
Executive Committee (WEC).
4.3.1 -2. Secure funding for the Upper Newport Bay Ecosystem Restoration
Project.
4.3.1 -3. Establish and protect a long -term funding source for the regular
dredging of Upper Newport Bay (including the Robinson - Skinner
Annuity) and dredging of the Lower Newport Bay so that the City and
its watershed partners achieve the goals and directives of the
Sediment and Nutrient TMDLs adopted for Newport Bay.
4.3.1 -4. Preserve, or where feasible, restore natural hydrologic conditions
such that downstream erosion, natural sedimentation rates, surface
flow, and groundwater recharge function near natural equilibrium
states.
4.3.1 -5. Require development on steep slopes or steep slopes with erosive
soils to implement structural best management practices (BMPs) to
prevent or minimize erosion.
4.3.1 -6. Require grading /erosion control plans to include soil stabilization on
graded or disturbed areas.
4.3.1 -7. Require measures be taken during construction to limit land
disturbance activities such as clearing and grading, limiting cut -and-
fill to reduce erosion and sediment loss, and avoiding steep slopes,
unstable areas, and erosive soils. Require construction to minimize
disturbance of natural vegetation, including significant trees, native
vegetation, root structures, and other physical or biological features
important for preventing erosion or sedimentation.

4.3.2 NPDES
The City of Newport Beach operates a
municipal separate storm sewer system
(MS4). The City's MS4 is permitted by
the Regional Board under the National
Pollutant Discharge Elimination System
( NPDES). The City's MS4 permit is
extensive in its obligation to keep
waterways clean by reducing or
eliminating contaminants from stormwater
and dry- weather runoff. MS4 permits
require an aggressive Water Quality
Ordinance (Ord. 97 -26), specific
Catch basin screens andRters municipal practices to maintain city
facilities like the MS4, and the use of
"best management practices" (BMPs) in many residential, commercial, and
development - related activities to further cut runoff. MS4 permits also require local
agencies to cooperatively develop a public education campaign to let more people
know about what they can do at home and at work to protect water quality.
Policies:
4.3.2 -1. Promote pollution prevention and elimination methods that minimize
the introduction of pollutants into coastal waters, as well as the
generation and impacts of dry weather and polluted runoff.
4.3.2 -2. Require that development not result in the degradation of coastal
waters (including the ocean, estuaries and lakes) caused by changes
to the hydrologic landscape.
4.3.2 -3. Support and participate in watershed -based runoff reduction and
other planning efforts with the Regional Board, the County of
Orange, and upstream cities.
4.3.2 -4. Continue to update and enforce the Newport Beach Water Quality
Ordinance.
4.3.2 -5. Develop and maintain a water quality checklist to be used in the
permit review process to assess potential water quality impacts.

4.3.2 -7. Incorporate BMPs into the project design in the following
progression:
• Site Design BMPs.
• Source Control BMPs.
Treatment Control BMPs.
Include site design and source control BMPs in all developments.
When the combination of site design and source control BMPs are
not sufficient to protect water quality as required by the LCP or
Coastal Act, structural treatment BMPs will be implemented along
with site design and source control measures.
4.3.2 -8. To the maximum extent practicable, runoff should be retained on
private property to prevent the transport of bacteria, pesticides,
fertilizers, pet waste, oil, engine coolant, gasoline, hydrocarbons,
brake dust, tire residue, and other pollutants into recreational waters.
4.3.2 -9. To the maximum extent practicable, limit the use of curb drains to
avoid conveying runoff directly to the City's street drainage system
without the benefit of absorption by permeable surfaces and natural
treatments such as landscaped areas and planters.
4.3.2 -10. Provide storm drain stenciling and signage for new storm drain
construction in order to discourage dumping into drains.
4.3.2 -11. Require new development to minimize the creation of and increases
in impervious surfaces, especially directly connected impervious
areas, to the maximum extent practicable. Require redevelopment to
increase area of pervious surfaces, where feasible.
4.3.2 -12. Require development to protect the absorption, purification, and
retention functions of natural drainage systems that exist on the site,
to the maximum extent practicable. Where feasible, design drainage
and project plans to complement and utilize existing drainage
patterns and systems, conveying drainage from the developed area
of the site in a non - erosive manner. Disturbed or degraded natural
drainage systems should be restored, where feasible.

4.3.2 -13. Site development on the most suitable portion of the site and design
to ensure the protection and preservation of natural and sensitive
site resources by providing for the following:
A. Protecting areas that provide important water quality benefits,
areas necessary to maintain riparian and aquatic biota and /or
that are susceptible to erosion and sediment loss;
B. Analyzing the natural resources and hazardous constraints of
planning areas and individual development sites to determine
locations most suitable for development;
C. Preserving and protecting riparian corridors, wetlands, and
buffer zones;

significant trees, native vegetation, and root structures;
E. Ensuring adequate setbacks from creeks, wetlands, and other
environmentally sensitive habitat areas;
F. Promoting clustering of development on the most suitable
portions of a site by taking into account geologic constraints,
sensitive resources, and natural drainage features
G. Utilizing design features that meet water quality goals
established in site design policies.
4.3.2 -14. Whenever possible, divert runoff through planted areas or sumps
that recharge the groundwater dry wells and use the natural filtration
properties of the earth to prevent the transport of harmful materials
directly into recreational waters.
4.3.2 -15. Where infiltration of runoff would exacerbate geologic hazards,
include equivalent BMPs that do not require infiltration.
4.3.2 -16. Require structural BMPs to be inspected, cleaned, and repaired as
necessary to ensure proper functioning for the life of the

maximum extent practicable.
4.3.2 -18. Condition coastal development permits to require the City, property
owners, or homeowners associations, as applicable, to sweep
permitted parking lots and public and private streets frequently to
remove debris and contaminated residue.
4.3.2 -19. Require parking lots and vehicle traffic areas to incorporate BMPs
designed to prevent or minimize runoff of oils and grease, car battery
acid, coolant, gasoline, sediments, trash, and other pollutants to
receiving waters.
4.3.2 -20. Require commercial development to incorporate BMPs designed to
prevent or minimize the runoff of pollutants from structures,
landscaping, parking areas, loading and unloading dock areas, repair
and maintenance bays, and vehicle/equipment wash areas.
4.3.2 -21. Require service stations, car washes and vehicle repair facilities to
incorporate BMPs designed to prevent or minimize runoff of oil and
grease, solvents, car battery acid, coolant, gasoline, and other
pollutants to stormwater system from areas including fueling areas,
repair and maintenance bays, vehicle/equipment wash areas, and
load inglunloading dock areas.
4.3.2 -22. Require beachfront and waterfront development to incorporate BMPs
designed to prevent or minimize polluted runoff to beach and coastal
waters.
4.3.2 -23. Require new development applications to include a Water Quality
Management Plan (WQMP). The WQMP's purpose is to minimize to
the maximum extent practicable dry weather runoff and runoff from
small storms (less than 314" of rain falling over a 24 -hour period)
during construction and post - construction from the property.
4.3.2 -24. To further reduce runoff, direct and encourage water conservation
via the use of weather- and moisture -based irrigation controls, tiered
water consumption rates, and native or drought - tolerant plantings in
residential, commercial, and municipal properties to the maximum
extent practicable.
4.3.2 -25. Effectively communicate water quality education to residents and
businesses, including the development of a water quality testing lab

and educational exhibits at the Back Bay Science Center on
Shellmaker Island.
4.3.3 Sanitary Sewer Overflows
The City of Newport Beach owns and operates a wastewater collection system
that collects residential and commercial wastewater and transports it, using a
system of 20 pump stations, for treatment by the Orange County Sanitation
District. Residences and businesses -- when permitted by the City -- hook up
private lateral lines to the City's collection lines. Private and public lines and the
City's pump stations have the potential to cause sanitary sewer overflows (SSOs).
SSOs lead to several beach closures in and around Newport Beach each year.
State law (AB 411, Wayne) requires local health officials to close receiving waters
to recreational uses when health officials know of or suspect that an SSO could
reach recreational waters. As such, SSOs in Newport Beach and in inland cities
can cause closures to Newport Beach's waters.
Most SSOs in the area are caused by line blockages. The primary causes of line
blockages are grease and root clogs. Newport Beach has adopted regulations for
the disposal of grease and other insoluble waste discharges from commercial food
preparation facilities to prevent blockages of the sewer system and is investigating
alternative grease control methods.
As a part of the City's Sewer System Management Plan (SSMP), the City's Utilities
Department follows a defined Sewer Master Plan to replace or reline older
wastewater lines. Newport Beach also uses remote cameras in sewer lines to
look for pipe cracks, root intrusion, and grease buildup to assist in prioritizing the
line replacement program.
Maintenance failures of plumbing associated with pump stations are another
leading cause of SSOs. Newport Beach's Sewer Master Plan includes upgrades
of its pump stations, including replacing pump stations with gravity systems where
possible. Upgraded pump stations also include spill- warning systems with multiple
communication methods (radio, telephone, pager, and direct line to the City's
Utilities yard) to inform Utilities staff of any malfunction.
Public education plays an important role in preventing and controlling SSOs.
Through water billing and other means, the City reminds the public -- and
especially restaurants -- to clean sewer laterals often, maintain private grease
control systems, keep roots under control, and to immediately report SSOs.

4.3.3 -2. Conduct additional public education reminding property owners and
food prepartion facilities to clean sewer laterals often, maintain
private grease control systems, keep roots under control, and to
immediately report SSOs.
4.3.3 -3. Require waste discharge permits with all food preparation facilities
that produce grease and require such permits to include:
• Agreements to follow appropriate BMPs;
• Maximum grease intrusion levels;
• Maintenance /posting of appropriate educational material;
• Maintenance log for laterals (at least quarterly);
• Maintenance of a log for any grease control device or vat;
• Funding for regular compliance inspections;
• Acknowledgement of City's ability to fine for non - compliance.
4.3.3 -4. Monitor food preparation facilities via waste discharge permits and
monitor spill reduction progress.
4.3.3 -5. Participate with other sewer collection and treatment agencies to
investigate alternatives to grease interceptors.
4.3.3 -6. Continue to renovate all older sewer pump stations and install new
plumbing according to most recent standards.

Coastal Act policies related to scenic and visual resources that are relevant to Newport Beach
include the following:
30251. The scenic and visual qualities of coastal areas shall be considered and protected as a resource of public importance.
Permitted development shall be sited and dagned to protect dews to and along the ocean and scenic coastal areas, to
minimize the alteration of natural land farms, to be visually compatible with the character of surrounding areas, and, where
feasible, to restore and enhance visual quality in visually degraded areas. New development in tigliy scenic areas such as
those designated in the California Coastline Preservation and Recreation Plan prepared by the Department of Parks and
Recreation and by local govemmert shall be subordinate to the character of its setting.
4.4.1 Coastal Views
Newport Beach is located in a unique physical setting that provides a variety of
spectacular coastal views, including those of the open waters of the ocean and
bay, sandy beaches, rocky shores, wetlands, canyons, and coastal bluffs. The
City has historically been sensitive to the need to protect and provide access to
these scenic and visual resources and has developed a system of public parks,
piers, trails, and viewing areas. Coastal views are also provided from a number of
streets and highways and, due to the grid street pattern in West Newport, Balboa
Peninsula, Balboa Island, and Corona del Mar, many north -south tending streets
provide view corridors to the ocean and bay.

Design and site such structures to minimize impacts to public coastal
views.
4.4.2 Bulk and Height Limitation
Concern over the intensity of
development around Lower
Newport Bay led to the adoption
of a series of ordinances in the
early 1970s that established more
restrictive height and bulk
development standards around
the bay. The intent was to
regulate the visual and physical
mass of structures consistent with
the unique character and visual
scale of Newport Beach. As a
result, new development within
the Shoreline Height Limitation
Homes on the Balboa Pennsula Zone is limited to a height of 35
feet. Residential development is
limited to a height of 24 to 28 feet and non - residential development is limited to a
CITY COUNCIL DRAFT 1 Local Coastal Program
Coastal Land Use Plan
4 -68
height of 26 to 35 feet. Outside of the Shoreline Height Limitation Zone, heights
up to 50 feet are permitted within the planned community districts. There are also
two properties in the coastal zone that are within the High Rise Height Limitation
Zone, which are permitted heights up to 375 feet. The first is the site of Newport
Beach Marriott Hotel in Newport Center; the other is an undeveloped office site
northeast of the Jamboree Road /State Route 73 interchange.
Floor areas are strictly limited citywide. In the coastal zone, residential
development is limited to floor areas ranging from 1.5 to 2.0 times the buildable
area of the parcel (the land minus required setback yards), which typically
translates to actual floor area ratios of 0.95 to 1.35. Nonresidential development
floor area ratios range from 0.30 to 1.25.
Policies:
4.4.2 -1. Maintain the 35 -foot height limitation in the Shoreline Height
Limitation Zone.
4.4.2 -2. Continue to regulate the visual and physical mass of structures
consistent with the unique character and visual scale of Newport
Beach.
4.4.3 Coastal Bluffs
Coastal bluffs are a prominent
landform in Newport Beach. There
are ocean facing coastal bluffs
along the shoreline of Corona del
Mar, Shorecliffs, and Cameo
Shores. There are also coastal
bluffs facing the wetlands of Upper
Newport Bay, Semeniuk Slough,
and the degraded wetlands of the
Banning Ranch property. Finally,
there are coastal bluffs
surrounding Lower Newport Bay.
These can be seen along Coast
Highway from the Semeniuk Upper Newport Bay coastal duffs
Slough to Dover Drive and in
Corona del Mar above the Harbor
Entrance. These bluffs faced the open ocean before the Balboa Peninsula formed
and are now generally separated from the shoreline. Coastal bluffs are considered
significant scenic and environmental resources and are to be protected.

Most of the coastal bluff top lands have been subdivided and developed over the
years. However, many have been preserved as parkland and other open space.
Also, most of the faces of the coastal bluff surrounding the Upper Newport Bay
have been protected by dedication to the Upper Newport Bay Nature Preserve or
dedicated as open space as part of planned residential developments. In other
areas, including Newport Heights, Cliff Haven, Irvine Terrace, Corona del Mar,
Shorecliffs, and Cameo Shores, the coastal bluffs fall within conventional
residential subdivisions. Development on these lots occurs mainly on a lot -by -lot
basis. As a result, some coastal bluffs remain pristine and others are physically or
visually obliterated by structures, Iandform alteration or landscaping.
Policies regarding coastal bluffs need to make a distinction between areas where
the coastal bluff is essentially unaltered and those in developed areas where the
coastal bluff has been altered. In areas with unaltered coastal bluffs, development
on the bluff face should be prohibited, with exceptions for certain public
improvements, and development of bluff top should be controlled. In areas where
the coastal bluff has been altered, development on the bluff face and bluff top
should be controlled to minimize further alteration.
The bluffs along Bayside Drive were at one time exposed to the Lower Newport
Bay. However, these bluffs separated from the shoreline when abutting tidelands
were filled and reclaimed in the 1920s and later developed into the communities of
Promontory Bay, Beacon Bay, and Bayside. Later development of Irvine Terrace
and Promontory Point cut and filled these bluffs to an extent that they can be best
identified as manufactured slopes rather than natural slopes. Given that the bluffs
along Bayside Drive have faces that are not the result of erosion, faulting, or
folding and are no longer subject to marine erosion, they did not meet the
definition of coastal bluffs and are not subject to the policies of this section.

Policies:
4.4.3 -1. In areas where the coastal bluff remains essentially unaltered,
require new development to dedicate or preserve as open space the
bluff face and an area inland from the edge of the bluff adequate to
provide safe public access and to avoid or minimize visual impacts.
4.4.3 -2. In areas where the coastal bluff remains essentially unaltered,
require all new development located on a bluff top to be setback from
the bluff edge a sufficient distance to ensure that it will not be
endangered by erosion and to avoid the need for protective devices
during the economic life of the structure (75 years).
4.4.3 -3. In areas where the coastal bluff remains essentially unaltered,
prohibit development on bluff faces, except public improvements
providing public access, protecting coastal resources, or providing
for public safety. Permit such improvements only when no feasible
alternative exists and when designed and constructed to minimize
alteration of the bluff face, to not contribute to further erosion of the
bluff face, and to be visually compatible with the surrounding area to
the maximum extent feasible.
4.4.3 -4. In areas where the coastal bluff has been altered, establish setback
lines for principal and accessory structures based on the
predominant line of existing development along the bluff in each
block. Apply the setback line downward from the edge of the bluff
and /or upward from the toe of the bluff to restrict new development
from extending beyond the predominant line of existing development.
4.4.3 -5. In areas where the coastal bluff has been altered, design and site
development to minimize alteration of those portions of coastal bluffs
with slopes in excess of 20 percent (5:1 slope). Prohibit
development on those portions of coastal bluffs with unaltered
natural slopes in excess of 40 percent (2.5:1 slope), unless the
application of this policy would preclude any reasonable economic
use of the property.
4.4.3 -6. Coastal bluffs do not include bluffs along Bayside Drive that have
been cut and filled by the Irvine Terrace and Promontory Point
developments and are no longer subject to marine erosion.
4.4.3 -7. Require applications for new development to include slope stability
analyses and erosion rate estimates provided by a licensed Certified
Engineering Geologist or Geotechnical Engineer.

Coastal Land Use Plan
4 -71
4.4.3 -8. Employ site design and construction techniques to minimize
alteration of coastal bluffs, such as:
A. Siting new development on the flattest area of the site, except
when an alternative location is more protective of coastal
resources.
B. Utilizing existing driveways and building pads to the maximum
extent feasible.
C. Clustering building sites.
D. Shared use of driveways.
E. Designing buildings to conform to the natural contours of the
site, and arranging driveways and patio areas to be
compatible with the slopes and building design.
F. Utilizing special foundations, such as stepped, split level, or
cantilever designs.
G. Detaching parts of the development, such as a garage from a
dwelling unit.
H. Requiring any altered slopes to blend into the natural contours
of the site.
4.4.3 -9. Require new development adjacent to the edge of coastal bluffs to
incorporate drainage improvements, irrigation systems, and /or native
or drought - tolerant vegetation into the design to minimize coastal
bluff recession.
4.4.3 -10. Design and site new development to minimize the removal of native
vegetation, preserve rock outcroppings, and protect coastal
resources.
4.4.3 -11. Design land divisions, including lot line adjustments, to minimize
impacts to coastal bluffs.
4.4.3 -12. Identify and remove all unauthorized structures, including protective
devices, fences, and stairways, which encroach into coastal bluffs.

4.4.4 Signs and Utilities
The City has adopted special sign
regulations for the Mariner's Mile
commercial district and for the Balboa
Peninsula. These sign regulations
include limitations on freestanding and
roof signs, which have the greatest
potential to impact coastal scenic and
visual resources.
In some of the older neighborhoods,
electrical, telephone, cable television,
and other utility lines are still located
above ground. The City requires Overhead udliues were placed rodeo nd h Balboa Wage
utilities to be placed underground in all
new developments and has ongoing programs to remove and underground
overhead utilities through the establishment of underground utility districts.

4.4.4 -2.
4.4.4 -3.
4.4.4 -4.
4.4.4 -5.
4.4.4 -6.
4.4.4 -7
Design and site signs, utilities, and antennas to minimize visual
impacts to coastal resources.
Continue to implement the special sign regulations in Mariner's Mile
and on the Balboa Peninsula.
Update sign regulations for the West Newport, Marine Avenue, and
Corona del Mar commercial areas.
Implement programs to remove illegal signs and amortize legal
nonconforming signs.
Continue to strictly limit billboards and other off -site signs.
Continue to require new development to underground utilities.
Continue programs to remove and underground overhead utilities.

4.5 Paleontological Cultural Resources
Coastal Act policies related to paleontological, archaeological, and historical Resources
that are relevant to Newport Beach Include the following:
30244. where development waWd adversely impact anhaeoloocal or paleontological resources as ider0ed by the
State Historic Preservation Officer, reasonable mitigation measures shall be regL*W.
4.5.1 Paleontological and Archaeological Resources
Orange County's geologic history began 175 - 145 million years ago, in the Middle
to Late Jurassic Period. The oldest rocks in Orange County are located in the
central Santa Ana Mountains and contain fossils such as radiolarians, ammonites
and bivalves. These types of rocks and fossils indicate that this area was under
the ocean. Therefore, for most of its geologic history, Orange County was
underwater.
During the Miocene Epoch (26 — 7 million years ago) tectonic forces produced
mountain uplifts, initiated movement on the nascent San Andreas fault system,
and formed numerous coastal marine basins, including the Los Angeles Basin, of
which most of Orange County is a part. Orange County became a shallow bay as
the sea retreated. Miocene fossils are from both marine and land organisms, as
the area was a shallow sea surrounded by jungles and savannas.
Tectonic forces began to uplift the land during the Pliocene (7 - 2.5 million years
ago). The sea began to slowly recede from the coast. Each successive shoreline
is represented today by a marine terrace and can be seen in Corona del Mar
today. Three marine terraces can be seen north of Corona del Mar by driving
toward the beach on MacArthur Boulevard. Sandstone deposited in the Newport
Beach area in the late Pliocene contains a wealth of marine mammals, sea birds
and a variety of seashells.
The seas continued to regress during the cooler Pleistocene (2.5 million — 15,000
years ago), and tectonic forces continued to uplift the land. Although the
Pleistocene Epoch is called the "Ice Age," glacial ice never reached Southern
California. A heavily vegetated, marshy area extended inland beyond the
shoreline, and a great variety of vertebrate Ice Age animals lived in the area.
Fossils of Ice Age horses, elephants, bison, antelopes and Dire wolves have been
found at sites near the Castaways.
The first generally accepted period of human occupation of the Southern California
began around the end of the Pleistocene, about 10,000 to 12,000 years ago.
Some of the evidence of the earliest human occupation in Orange County was
found at archaeological sites around the Upper Newport Bay.

Tongva steatite bovA recovered from a development site
Policies:
These and other archaeological sites
in Newport Beach present evidence
that highly mobile and resourceful
people lived here as far back as 9,500
years ago. A village site excavated in
Newporter North was occupied at
various times over 5,500 years.
Archaeological excavations indicate
that the earliest people followed the
seasonal migration of animals and
collected a wide variety of wild plant
resources. Later inhabitants were
more sedentary, hunting sea
mammals, small and large terrestrial
mammals, fish, bird, and shellfish.
4.5.1 -1. Require new development to protect and preserve paleontological
and archaeological resources from destruction, and avoid and
minimize impacts to such resources. If avoidance of the resource is
not feasible, require an in situ or site - capping preservation plan or a
recovery plan for mitigating the effect of the development.
4.5.1 -2. Require a qualified paleontologist/archeologist to monitor all grading
and /or excavation where there is a potential to affect cultural or
paleontological resources. If grading operations or excavations
uncover paleontologicaVarchaeological resources, require the
paleontologist/archeologist monitor to suspend all development
activity to avoid destruction of resources until a determination can be
made as to the significance of the paleontological / archaeological
resources. If found to be significant, require the site(s) to be
preserved for a reasonable period of time to allow a recovery plan to
be completed to assure the protection of the
paleontological /archeological resources.
4.5.1 -3. Notify cultural organizations, including Native American
organizations, of proposed developments that have the potential to
adversely impact cultural resources. Allow qualified representatives
of such groups to monitor grading and /or excavation of development
sites.
4.5.1 -4. Require new development to donate scientifically valuable
paleontological or archaeological materials to a responsible public or

private institution with a suitable repository, located within Orange
County, whenever possible.
4.5.1 -5. Continue to protect Upper Newport Bay cliff faces to serve as a
reference section for micropaleontological studies.

4.5.2 Historical Resources
Newport Beach has a number of
buildings and sites in the coastal zone
that are representative of the history of
the community and the region. Some
of these historical resources have been
recognized as being of statewide or
national importance. There are four
properties in Newport Beach that are
listed as California Historical
Landmarks:
• Old Landing (No. 198). Established by Captain Dunnells in the
1870's, it was the site of the first shipping business in Newport Bay.
• Site Of First Water -To -Water Flight (No. 775). Commemorates the
May 10, 1912 flight of Glenn L. Martin from the waters of the Pacific
Ocean at Balboa to Catalina Island, the first water -to -water flight.
• McFadden Wharf (No. 794). The site of the original wharf built in 1888
by the McFadden brothers.
• Balboa Pavilion (No. 959). Built in 1905, it is one of California's last
surviving examples of the great waterfront recreational pavilions from
the turn of the century.

The Dory Fishing Fleet is located
adjacent to Newport Pier. The fleet and
open -air fish market has operated there
since its founding by a Portuguese
fisherman in 1891. The last remaining
fleet of its type, it is a historical
landmark designated by the Newport
Beach Historical Society. It is a general
policy of the City that an area
immediately west of the Newport Pier
be reserved for the Newport Dory
Fishing Fleet.
Policies:

4.5.2 -1. Continue to maintain the Newport Beach Register of Historical
Property for buildings, objects, structures, and monuments having
importance to the history or architecture of Newport Beach.
4.5.2 -2. Allow the application of the State Historical Building Code to
buildings or structures listed in the Newport Beach Register of
Historical Property.
4.5.2 -3. Provide incentives, such as granting reductions or waivers of
applications fees, permit fees, and/or any liens placed by the City to
properties listed in the Newport Beach Register of Historical Property
in exchange for preservation easements.
4.5.2 -4. Continue to allow the Dory Fishing Fleet to be launched and stored
and to sell fish on the public beach adjacent to Newport Pier within
reasonable limits to protect the historical character of the fleet, the
coastal access and resources, and the safety of beach users in the
vicinity.

5.0 Glossary
Accrete: To add new material gradually to pre- existing material; opposite of erode.
Accretion: Enlargement of a beach area caused by either natural or artificial means.
Natural accretion on a beach is the build -up or deposition of sand or sediments by
water or wind. Artificial accretion is a similar build -up due to human activity, such as
the accretion due to the construction of a groin or breakwater, or beach fill deposited
by mechanical means.
Anaerobic Soil: Soil that is devoid of interstitial oxygen. In wetlands this condition
most normally occurs because of the sustained presence of water, which limits
contact with the atmosphere.
Anchorage Area: A water area outside of navigation channels designated for the
temporary anchorage of vessels, using their own anchoring tackle.
Appealable Area: That portion of the coastal zone within an appealable area
boundary adopted pursuant to Section 30603 of the Coastal Act and approved by the
Coastal Commission and depicted on the Permit and Appeal Jurisdiction Map.
Aquaculture: A form of agriculture as defined in Section 17 of the Fish and Game
Code. Aquaculture products are agricultural products, and aquaculture facilities and
land uses shall be treated as agricultural facilities and land uses in all planning and
permit- issuing decisions governed by this division.
Aquifer: An underground layer of porous rock, sand, or other earth material
containing water, into which wells may be sunk.
Armor: To fortify a topographical feature to protect it from erosion (e.g., constructing
a wall to armor the base of a sea cliff).
Armor Rock (armor stone): Natural or man -made rock or rock -like structures that are
used for shoreline protection. Commonly, armor rock is used as the outermost layer
of a groin or revetment. Many forms of these rocks are utilized; their overall stability
depends largely on the type of mechanical interlock between the units, and in -place
fitting.
Artificial Hard Structure: Docks, floats, boat bottoms, bulkheads, seawalls, and other
hard surfaces that provide attachment surfaces for marine organisms.
