A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
NEWPORT BEACH, CALIFORNIA, AMENDING THE CITY
OF NEWPORT BEACH DESIGN CRITERIA AND
STANDARD DRAWINGS FOR PUBLIC WORKS
CONSTRUCTION AND THE WATERFRONT PROJECT
GUIDELINES AND STANDARDS, HARBOR DESIGN
CRITERIA, COMMERCIAL AND RESIDENTIAL FACILITIES
RELATED TO MULTIPLE VESSEL MOORING SYSTEMS
WHEREAS, the City of Newport Beach Waterfront Project Guidelines and
Standards, Harbor Design Criteria, Commercial and Residential Facilities ("Harbor
Design Guidelines") provide a standard for the design of structures in Newport Harbor;
WHEREAS, the Harbor Design Guidelines are now incorporated into the City of
Newport Beach Design Criteria & Standard Drawings for Public Works Construction, 2021
Edition ("Public Works Design Standards") adopted by the City Council pursuant to
Resolution 2021-23 on March 23, 2021;
WHEREAS, a multiple vessel mooring system ("MVMS") consists of a floating
platform at a single-vessel mooring location to which multiple smaller boats berth via side -
tie, thereby allowing for increased boat storage;
WHEREAS, there are approximately twelve MVMS within Newport Harbor's two
single anchor mooring systems (Newport Harbor Yacht Club and Balboa Yacht Club
mooring fields), yet plans and specifications for the MVMS have not been adopted;
WHEREAS, the Harbor Commission reviewed and approved the proposed MVMS
plans and specifications at its November 10, 2021 meeting and their recommendation is
presented to the City Council for review and approval; and
WHEREAS, Newport Beach Municipal Code section 17.35.010 authorizes the
amendment of the Harbor Design Guidelines by resolution of the City Council.
NOW THEREFORE, the City Council of the City of Newport Beach resolves as
follows:
Section 1: Section I.A.6.e (Special Mooring Devices) of the Harbor Design
Guidelines is amended to add a new paragraph (3) to read as follows, with all other
provisions of the Harbor Design Guidelines to remain unchanged:
Resolution No. 2022-9
Page 2 of 4
(3) Multiple Vessel Mooring System (MVMS) allows multiple vessels to be
secured to a floating platform which is secured to a single anchor
mooring system in Newport Harbor. This allows multiple vessels to side -
tie to the floating platform therefore increasing vessel capacity at a
mooring location. The intent of the MVMS is to provide increased small -
boat storage at a mooring location within the single anchor mooring
fields.
(a) MVMS requests must be approved by the Harbor Department
and Public Works Department prior to installation. Because of the
potential conflict with adjacent moorings due to the increased
mooring footprint, only single -hulled vessels will be permitted
within the MVMS.
(b) MVMS floats shall follow material and construction requirements
as noted in these Harbor Design Criteria. The MVMS float width
shall be 6 -feet. The MVMS float length shall be either 20 -feet or
40 -feet. The mooring tackle weight and chain specification for
MVMS is maintained by the Harbor Department. The minimum
specification for mooring tackle is calculated based on the
maximum capacity (vessel size and number of vessels) for either
the 20 -foot or 40 -foot MVMS, respectively.
(c) The maximum vessel length overall (LOA) on each side of the
MVMS shall be 22 feet. The maximum vessel overhang beyond
the ends of the float shall be 3 feet. Vessels secured to the MVMS
shall be side -tied in such a manner as to ensure the security of
such vessels fore (bow) and aft (stern) at a minimum.
(d) The maximum overall width of the MVMS system including the 6 -
foot -wide float (i.e., boat + MVMS + boat) shall be 25 feet.
(e) Coolers, benches, furniture, boat covers, trash, debris, or other
items shall not be used or stored on the MVMS at any time. Up
to 2 locker "dock" boxes may be permitted on the MVMS by the
Harbor Department and shall follow material and installation
requirements as set forth in these Harbor Design Criteria. No
flammable, combustible or otherwise hazardous material shall be
stored in the dock boxes or on the MVMS. A dock box shall be
secured using reasonable commercial standards approved by the
Harbor Department and shall only hold enough items so that the
dock box cover remains fully closed at all times.
Resolution No. 2022-9
Page 3 of 4
(f) The MVMS shall adhere to all provisions for harbor structures as
stated in NBMC Title 17 including, but not limited to, "appropriate
deterrent measures" to deter sea lions from boarding the MVMS.
Section 2: The Harbor Design Guidelines, as amended, are attached hereto as
Exhibit "A" and incorporated herein by reference.
Section 3: The Public Works Design Standards are amended to add Standard
Drawing No. 617 "Multiple Vessel Mooring System" which is attached hereto as Exhibit
"B" and incorporated herein by reference.
Section 4: The recitals provided in this resolution are true and correct and are
incorporated into the operative portion of this resolution.
Section 5: If any section, subsection, sentence, clause or phrase of this
resolution is, for any reason, held to be invalid or unconstitutional, such decision shall not
affect the validity or constitutionality of the remaining portions of this resolution. The City
Council hereby declares that it would have passed this resolution and each section,
subsection, sentence, clause or phrase hereof, irrespective of the fact that any one or
more sections, subsections, sentences, clauses or phrases be declared invalid or
unconstitutional.
Section 6: The City Council finds the adoption of this resolution is not subject to
the California Environmental Quality Act ("CEQA") pursuant to Section 15060(c)(2) (the
activity will not result in a direct or reasonably foreseeable indirect physical change in the
environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378)
of the CEQA Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3
because it has no potential for resulting in physical change to the environment, directly or
indirectly.
Resolution No. 2022-9

Code and Council Policy H-1.
Dock systems shall be designed by a civil or structural engineer, licensed by the State of
California, who is experienced in the design of marine structures. Repairs and non-structural
modifications to existing residential docks can be designed by a licensed contractor experienced
in dock facilities, at the discretion of the City of Newport Beach.
In accordance to California Building Code [A] 104.10 Modifications. "Wherever there are
practical difficulties involved in carrying out the provisions of this code, the [Chief] Building
Official shall have the authority to grant modifications for individual cases, upon application of
the owner or owner's representative, provided the [Chief] Building Official shall first find that
special individual reason makes the strict letter of this code impractical and the modification is
in compliance with the intent and purpose of this code and that such modification does not lessen
health, accessibility, life and fire safety, or structural requirements. The details of action granting
modifications shall be recorded and entered in the files of the department of building safety."
Fire Marshal approval shall be required for variances associated with the fire protection system.
In accordance to California Building Code [A] 104.11 Alternative materials, design and methods
of construction and equipment. "The provisions of this code are not intended to prevent the
installation of any material or to prohibit any design or method of construction not specifically

I. WATERSIDE DEVELOPMENT
The limits and constraints of construction in the harbor are defined by a series of lines that have
been established over time by the Federal Government, as well as the City of Newport Beach.
These lines have been defined in Chapter 17.01 of the Municipal Code. Prior to the preparation
of documents to be submitted to the City of Newport Beach for review of a proposed project, the
applicant should obtain a full understanding of these lines and have a qualified engineer, surveyor
or contractor define these lines on any plans submitted for a proposed project. These lines include
the existing or current edge of construction along the waterfront with respect to the Federal
Bulkhead, Pierhead and Project Lines, Channel Lines, property lines (and their projections),
Anchorage Area, and Turning Basins.
A. DOCKS
1. ALTERNATIVE BERTHING GEOMETRIES
Various berthing geometries are available and acceptable for the berthing of boats
for a docking facility. The following layouts and designs present the generalized
arrangements that are considered acceptable to the City of Newport Beach for the
berthing of boats. The attached Figures and "Case" geometries can be utilized as
shown, or in combination with one another, in an overall marina dock scheme.
2. LAYOUT AND DESIGN
(Commercial & Residential)
a. General
(1) Layout and design of harbor facilities shall be based upon the use
of the facility defined as follows:
(a) Single or joint residential
(b) Multi -residential
(c) Commercial (Type 1): typical
1) Passenger (e.g., ferry, event cruise, etc. with no on -
dock queuing)
2) Recreational boat marina
3) Yacht club
4) Other commercial (e.g., restaurant, office, yacht
broker, etc.)
5) Public pier
(d) Commercial (Type 2): not common in Newport Harbor
1) On -dock passenger staging (i.e., where passengers
queue on the dock prior to boarding)
2) Docks used for transfer of cargo or other materials
(2) Layout and Design Guidelines for Marina Berthing Facilities
(2005 edition or as updated) published by the State of California
State Parks Division of Boating and Waterways, except as
modified by the City's Harbor Standard Drawings within the
Design Criteria may be used as a guide to design harbor structures.
(3) See the attached Harbor Standard Drawings for plans, sections
and details of typical conditions for vessel moorings and docks,
gangways, platforms, seawalls, and beach profiles. These
Standards are to be considered minimum requirements for the
cases represented and, at the City of Newport Beach discretion,
may not apply to the specific project submitted. The City of
Newport Beach reserves the right to mandate deviation from the
Standards, if particular project conditions require special
consideration.
b. Slip and Boat Overhang into Adjacent Fairways
(1) Berths shall not be occupied by vessels more than three (3) feet
longer than the berth or slip, or in the case of fairways with a width
of 1.75 x Lb (length of berth), not more than 10% of the length of
the berth's finger.
(2) For berths either parallel or perpendicular to a main channel,
vessels can extend beyond the limits of the slip by as much as the
beam of the boat.
C. Finger and Walkway Widths
(1) Minimum finger widths for recreational, commercial, and
residential docks shall be per Table No. 1.
(2) Fillets at the connection of walkways to fingers shall not have less
than a 4 -foot side.
(3) Outer end (end tie) and side -tie fingers shall be a minimum of one
foot wider than the minimal widths for all other adjacent finger
docks.
(4) Residential Headwalks and Mainwalks
IJ
(a) Minimum residential headwalk widths shall be no less than
six (6) feet for dock lengths up to 120 feet in total length,
and eight (8) feet wide for dock lengths of more than 120
feet.
(5) Commercial Headwalks and Mainwalks
(a) Minimum widths shall be no less than six (6) feet for dock
lengths up to 120 feet in total length, and eight (8) feet wide
for dock lengths of more than 120 feet. If use of a walkway
is for staging the public while waiting to board a vessel, the
minimum dock width shall be 12 feet.
(b) At gangways, a minimum of six (6) feet of walking surface
shall be maintained in front of the farthest gangway
projection (including toe plate) at high tide, and have a
minimum of four (4) feet of clear space to walk along the
side of any gangway for access to berthed vessels.

Minimum 5.0' widths are required for the entire path of travel for
ADA access, including paths along main- and headwalks. See
Section 5 of these Harbor Design Criteria for exceptions.
Single and Double -Wide Slips
(1) Single -wide slips are those slips that have a finger on each side of
the boat. Double -wide slips have only one finger adjacent to any
given boat.
10
e. Vessel "Rafting"
(1) Vessel "rafting" is the practice of connecting multiple vessels
together, with only one of the vessels being tied/berthed to a
walkway or finger. Rafting of vessels is not allowed, unless
specifically approved by the City's Harbor Department and/or the
Fire Department for special facilities and/or events.
Long Docks
(1) Long docks are defined as side -tie docks with more than one boat
berthed. Unless specifically identified otherwise, and for the
purpose of establishing the number of boats that may utilize a long
dock per DB W Layout and Design Guidelines for Marina Berthing
Facilities (2005 edition or as updated), it will be assumed that one
boat is berthed alongside a long dock every 40 feet of long dock
length. This would relate to a 30 -ft berthed boat, with five (5) feet
of clearance on either end. Distance between two adjacent boats
shall be minimum 10 feet.
g. Loading Criteria
(1) The design of the dock system shall incorporate all anticipated
dead and live loads. These criteria conform to DBW Layout and
Design Guidelines for Marina Berthing Facilities (2005 edition or
as updated).
(a) Dead Loads: Dead loads shall include the weight of the
dock system components (walers, bracing, bracket, etc.),
which are permanently incorporated into the dock system,
and non -dock system components (transformers, dock
boxes, gangways, pumps, dinghy/kayak/SUP racks, trash
containers, buildings, etc.) which are permanently affixed
to the dock system.
(b) Live Loads: Live loads are loads produced by the use of
the dock system, such as people, carts, mobile equipment,
etc. The dock system shall be capable of supporting live
loads and freeboards per the "Flotation and Freeboards"
section in these standards. The structure shall also be
capable of supporting a 400 -pound moving point load
anywhere on the deck surface, but no closer than 12" from
any dock edge, while maintaining the level tolerances cited
in this guideline.
11
(c) Wildlife Loads: Refer to DBW Layout and Design
Guidelines for Marina Berthing Facilities (2005 edition or
as updated) for live loads imposed by wildlife on the docks.
These wildlife live loads may include sea lions.
(2) Wind loads shall be calculated both parallel to and perpendicular
to the maximum length of vessels and structures in accordance to
current California Building Code.
(a) Wind load on the lateral area of vessels or structures shall
not be less than 15 pounds per square foot acting on the
projected area of the docks as well as the profile area - "sail
area" of the berthed vessels above water level.
(b) Lateral area of vessels for wind load calculations acting on
the "sail area" of the vessel shall be as per Exhibit No. 1,
or the actual sail area of the anticipated vessel, whichever
is greater.
(c) Ten percent (10%) of the full wind load for an unshielded
vessel shall be applied to each vessel in the leeward side of
the unshielded vessel.
(3) Current Loading: Floating docks in areas of the harbor may be
subject to current loads. Dock shall be designed for minimum
current velocity of 1 feet per second (1 feet/sec).
(4) Impact Loading: Impact Load from design vessel (maximum boat
size that may be moored on the dock) striking dock at 10 degree
angle (from parallel to dock) with approach speed of minimum one
feet per second (1 feet/sec).
(5) Wave Loading: A simple wave analysis was conducted to provide
general guidance of a 100 -year return period wind waves and
ocean swells at Newport Harbor. In general, the majority of
Newport Harbor is dominated by wind waves except for the areas
near the harbor entrance which are dominated by ocean swells.
Contact the City of Newport Beach, Public Works Department for
details of reference study.
A qualified civil engineer, licensed in the State of California, shall
conduct site-specific engineering analysis to evaluate the
appropriate design wave loading for the project.
(6) Environmental Loads: Refer to DBW Layout and Design
Guidelines for Marina Berthing Facilities (2005 edition or as
12
updated) for impact loads imposed by flooding, abandoned boats,
broken docks, jetsam, tree limbs, or other debris. Environmental
loads may occur throughout the Harbor but specifically in the
Upper Bay and near the West Coast Highway bridge.
(7) Load Combinations
(a) Combined load cases for design of docks shall include the
following:
1) Dead load plus uniform live load.
2) Dead load plus concentrated 400-1b live load.
3) Dead load plus wind load plus current & wave
loads.
4) Dead load plus impact load.
(b) Fabrication, handling, and lifting loads shall also be
checked in the calculation of the dock system.
(c) For design of wood structures, the load duration factors in
Table 2.3.2 of the latest edition of the American Wood
Council National Design Specifications (NDS) may be
applied. Allowable Stress Design and Load and Resistance
Factor Design values for wood members shall be reduced
by the Wet Service Factor according to Tables 4.3.1, 5.3.1
and 8.3.1 of the NDS.
(d) Calculations shall include the transfer of forces from the
dock system into the piles. All components within this
transfer mechanism shall be substantiated.
(e) Load combinations for vertical load bearing structural
elements (i.e., piers, wharves, and platforms) in Section
1605 of the California Building Code (2019 or latest
edition) and Section 5.3 of the Building Code
Requirements for Structural Concrete (ACI 318-19 or
latest edition) respectively, shall apply.

h. Flotation and Freeboards
(1) Sufficient flotation shall be provided to support dead load plus live
load with freeboards as noted below. Higher live load requirements
may be required by the City of Newport Beach, under special
circumstances as may be deemed appropriate.
Dock freeboard shall be minimum 14 inches and maximum 24
inches, under dead load. Dock freeboard shall not be less than nine
(9) inches and there shall be minimum one (1) inch of pontoon
freeboard remaining, under dead plus live load. See Figure No. 13
for typical concrete dock system (where dock system itself is the
pontoon) and Figure No. 14 for typical timber, aluminum, steel,
and composite framing dock system (where framing is supported
by pontoons).
(a) Residential docks, including multi -family residential, shall
be designed for a live load of 25 pounds per square foot.
(b) Marinas, Public Pier (also known as Public Docks) and
Commercial Docks (Type 1 docks subject to high volumes
of pedestrian traffic such as docks used for ferries, charter
boats, fishing boats, boat shows, shuttles, water taxis, etc.)
shall be designed for a live load of 40 pounds per square
foot. Type 1 commercial docks are typical in Newport
Harbor.
Commercial Docks (Type 2), as previously described,
which are also used for the on -dock staging (queuing) of
passengers, or are subject to high volumes of cargo or other
materials, shall be designed for live load of 65 pounds per
square foot. Signage indicating maximum number of
people (using occupant load factor 200 pounds/person) that
may be staged (Dock Staging Capacity) shall be posted at
a prominent location at staging area. Type 2 commercial
docks are not common in Newport Harbor.
Exception 1: Docks whose functionality requires dead load
freeboard less than 14 inches (docks used for kayaks,
rowboat, etc.) shall be designed for 25 pounds per square
foot live load. These special docks shall be exempt from
the freeboard requirement on "Floatation and Freeboard"
in Section U. Signage indicating maximum number of
people (using occupant load factor = 200 pounds/person)

member should walk the suction pipe alignment to check for red
dye in the Harbor water. The pump operation and the discharge
pipe shall be inspected for leaks as well.
Floating Buildings
(1) To obtain approval from the City of Newport Beach Harbor
Department, Public Works Department, Development Services
Department, and Planning Department for the installation of a
floating building, the applicant must provide compelling reasons
that such a facility is necessary and is precluded from location on
land. Appropriate regulatory approvals are also required.
(2) Only commercial facilities are allowed to consider floating
buildings. Residential facilities are not allowed to have floating
buildings. Potential floating building uses include restrooms, the
dock master's office, enclosures on a floating fuel dock, and boat
rental office. Other uses may be considered, at the discretion of
the City of Newport Beach.
(3) Floating buildings are subject to the latest edition of all local, State
and Federal building codes.
32
d. Vessel Launching Facilities
(1) Vessel launching facilities may include vehicle launch ramps for
trailered boats, concrete launch ramps with rails and/or tracks for
special vessel carriers, elevated travel lift launches, swing hoists
on davits, and forklift launching.
(2) All launch facilities shall be designed considering the launching
and vehicle loads imposed on existing and/or planned structures.
(3) Vessel launching facilities shall be designed in accordance with
Layout, Design, and Construction Handbook for Small Craft Boat
Launching Facilities (1991 edition or as updated) published by
the California State Parks Division of Boating and Waterways.
Special Mooring Devices
(1) Special vessel mooring devices may be required or desired for
specific berthing conditions. Large vessels may require mooring
and/or breasting dolphins (pile groupings designed to resist large
impact and berthing loads), berthing walls, or other devices that
facilitate vessel docking.
(2) Special mooring devices shall be designed by a California -licensed
Civil or Structural Engineer with input provided by California -
licensed Geotechnical Engineer, all with experience in waterfront
engineering. Special mooring devices shall be designed to resist
berthing loads, wind, wave, and current loading for the localized
area.
(3) Multiple Vessel Mooring System (MVMS) allows multiple vessels
to be secured to a floating platform which is secured to a single
anchor mooring system in Newport Harbor. This allows multiple
vessels to side -tie to the floating platform therefore increasing
vessel capacity at a mooring location. The intent of the MVMS is
to provide increased small -boat storage at a mooring location
within the single anchor mooring fields.
(a) MVMS requests must be approved by the Harbor
Department and Public Works Department prior to
installation. Because of the potential conflict with adjacent
moorings due to the increased mooring footprint, only
single -hulled vessels will be permitted to use the MVMS.
(b) MVMS floats shall follow material and construction
requirements as noted in the Harbor Design Criteria. The
33
MVMS float width shall be 6 -feet. The MVMS float length
shall be either 20 -feet or 40 -feet. The mooring tackle
weight and chain specification for MVMS is maintained by
the Harbor Department. The minimum specification for
mooring tackle is calculated based on the maximum
capacity (vessel size and number of vessels) for either the
20 -foot or 40 -foot MVMS, respectively.
(c) The maximum vessel length overall (LOA) on each side of
the MVMS shall be 22 -feet. The maximum vessel
overhang beyond the ends of the float shall be 3 -feet.
Vessels secured to the MVMS shall be side -tied in such a
manner as to assure the security of such vessels fore (bow)
and aft (stern) at a minimum.
(d) The maximum overall width of the MVMS system
including the 6 -foot -wide float (i.e., boat + MVMS + boat)
shall be 25 -feet.
(e) Coolers, benches, furniture, boat covers, trash, debris, etc.
shall not be used or stored on the MVMS at any time. Up
to two (2) locker "dock" boxes may be permitted on the
MVMS by the Harbor Department and shall follow
material and installation requirements as noted in the
Harbor Design Criteria. No flammable, combustible or
otherwise hazardous material shall be stored in the dock
boxes or on the MVMS. A dock box shall be secured using
reasonable commercial standards approved by the Harbor
Department and shall only hold enough items so that the
dock box cover remains fully closed at all times.
(f) The MVMS shall adhere to all provisions for harbor
structures as stated in NBMC Title 17 including, but not
limited to, maintaining appropriate measures to deter sea
lions from boarding the MVMS.
f. Piers, Platforms, and Wharves
(1) Piers, platforms, and wharves shall be designed by a California -
licensed Civil or Structural Engineer experienced in waterfront
structures. A geotechnical report, for pile design and installation,
shall be provided that addresses special issues such as liquefaction
potential, and the vertical (gravity) and seismic support of the
waterfront structure. The geotechnical report shall be prepared by
a California -licensed Geotechnical Engineer.
34
(2) Refer to the Harbor Standard Drawings for the various geometries
allowed for piers and platforms that serve and provide access to
residential floating docks.
(3) Commercial: Structures shall be designed for an assembly area live
load of 100 pounds per square foot (psf). If vehicles shall be used
on the structure for maintenance purposes, then vehicle loads shall
be used for the design of the structure. If vehicle loads exceed 100
psf, then vehicle loads shall govern.
(4) Residential: Structures shall be designed for a minimum live load
of 50 psf.
g. Seawalls (Bulkheads)
(1) General: Several types of seawalls are common to support soils
and construction on the landside of the wall. Seawall material can
be composed of various types of materials, including concrete,
steel, and other manufactured materials. Typical wall types include
freestanding or "cantilevered" seawalls and "tied -back" seawalls.
Cantilevered seawalls are limited by the height of the wall above
the waterside mudline and are generally effective for exposed
heights of not more than 8 feet. For structural steel type seawalls,
higher exposed heights are possible. Tied -back seawalls can be
effective for exposed heights over 8 feet and may require
continuous caps, walers (beams), steel tie rods and a foundation
anchors (deadman), or earth anchors. Tie -back anchor systems
shall require protection against corrosion. Galvanic anode cathodic
protection system is recommended. Tie -back anchor system shall
be designed to last the life of seawall.
(2) Generally, seawall sheets constructed of reinforced, prestressed
concrete are desirable, although for special conditions, structural
steel interlocking sheets may be necessary. Steel products in the
marine environment require special non-toxic coating protection
and cathodic protection, in order to provide extended life spans.
(3) The City understands there is a threat of flooding and inundation
in and around Newport Harbor due to sea level rise. Newport
Harbor and adjacent low-lying areas rely on a system of harbor
bulkheads, seawalls, revetments, or other improvements to
function. Additionally, the system of shoreline defenses protects
existing development, public access, public views, and scenic
qualities of the coastal zone. The City is committed to using the
best available science to determine a range of sea level rise
projections for use in developing harbor development standards
35
and in reviewing Coastal Development Permit applications.
Currently the best available science is the State of California Sea
Level Rise Guidance, 2018 Update. Experts acknowledge that
there is considerable uncertainty in the magnitude and rate of the
rise in sea level and as a result, the City recognizes the need to set
standards over time that provide protection from future sea level
rise given the inherent uncertainty of the rate and magnitude of the
rise.
Bulkheads, seawalls or other protective improvements shall be
constructed and maintained as shown in Table No. 2. The structure
shall also be initially designed and constructed to accommodate
and receive future increases in height when directed by the City to
protect adjacent low-lying areas from future flooding without the
need to replace or substantially alter the structure.

1. Derived using the Upper Limit of the Low Risk Aversion probabilistic sea level rise
protection scenario for the Los Angeles tidal gauge, estimated 75 years into the future
based on the State of California Sea Level Rise Guidance, 2018 Update. This scenario
accounts for the upper range of what is "likely to occur" with approximately an 83
percent probability that sea level rise falls below the elevations shown.
2. Derived using the Medium -High Risk Aversion probabilistic sea level rise protection
scenario for the Los Angeles tidal gauge, estimated 75 years into the future based on the
State of California Sea Level Rise Guidance, 2018 Update. This scenario accounts for
increased sea level with approximately a I -in -200 or 0.5 percent probability that sea
level rise exceeds the elevations shown.
(4) The distance between seawalls and all floating dock components
shall be a minimum of one foot horizontal distance.
(5) Seawalls shall be designed to resist all applicable vertical and
horizontal loads.
(6) A minimum safety factor of 1.5 shall apply to gravity loads, and a
minimum safety factor of 1.1 shall apply to seismic loading cases
for the stability of seawalls.
(7) Decking may butt to the seawall cap, or cantilever over the top of
the seawall, if approved.
(8) Wing Walls: Wing walls are retaining walls that project landward
and are perpendicular to the seawall. Wing walls may be necessary
to isolate the seawall protection system of one property to the
adjacent property. Special care must be taken to assure that the
construction of a seawall for the subject property does not
adversely impact the seawalls of the adjoining properties, either
during construction or over the life of the structures.
(9) Seawall design requires a soils report from a California -licensed
Geotechnical Engineer experienced with the design of waterfront
structures. Any sloping surface on the water or landside of the
seawall must be accounted for in the calculations for the seawall.
(10) All concrete sheets used for seawall construction shall be designed
as pre -cast, pre -stressed concrete elements. Sheet design shall
provide for symmetrical distribution and sizing of strands, to
prevent curvature of the wall. See Section 3.e "Pilings &
Anchorage" for concrete and reinforcing requirements.
(11) All seawalls or seawall alterations shall be designed by a
California -licensed Civil or Structural Engineer.
7. DREDGING
a. General
