Previous environmental documentation relating to the widening of Jamboree
Road is included in the City of Newport Beach, Final Environmental Impact
Report (EIR) for the Widening of Jamboree Road from MacArthur Boulevard to
Eastbluff Drive (North). The EIR contains baseline environmental informa-
tion and impact analyses for the widening of Jamboree Road between Ford
Road and MacArthur Boulevard. However, the EIR was certified only for the
portion of Jamboree Road between Eastbluff Drive (North) and MacArthur
Boulevard.
The Final EIRs for both the Aeronutronic Ford Planned Community - Tenta-
tive Tract #10391 and the North Ford Planned Community - Tentative Tract
#10019 addressed the widening of and modifications to the easterly side of
Jamboree Road. Certification of these Final EIRs, which occurred in
November 1979, resulted in the approval of a third northbound lane and
related modifications on Jamboree Road between Ford Road and Eastbluff
Drive (North).

I. PROJECT DESCRIPTION
A. INTRODUCTION
This Initial Study has been prepared in accordance with the California
Environmental Quality Act (CEQA), the State Guidelines for Implementing
CEQA, and City Policy K3. The study's purpose is to enable the City of
Newport Beach to determine whether the proposed widening of Jamboree Road
will have a significant impact on the environment and is designed to cover
all associated permits for this project.
The primary purpose of the project is to reduce traffic congestion and its
related adverse impacts by adding a third southbound lane along the
westerly side of Jamboree Road between Ford Road /Eastbluff Drive (South)
and Eastbluff Drive (North).l In addition, the proposed road widening
would bring Jamboree Road into compliance with City and County circulation
plans. This is described further in Section I, PROJECT OBJECTIVES and
Section III, LAND USE COMPATIBILITY.

The Initial Study is divided into six sections: Section I contains the
project description; Section II includes a discussion of local and
regional land uses relating to the project; Section III describes existing
conditions, impacts of the project and proposed mitigation measures;
Section IV lists organizations and persons consulted during the
preparation of -the Initial Study; Section V lists references used; and
Section VI incorporates appendix materials.
B. LOCATION
Jamboree Road is an important north -south arterial traversing the Cities
of Irvine and Newport Beach. Running between Barranca Road in Irvine at
the northern end to Bayside Drive in Newport Beach at the southern end, it
crosses several major or primary arterials and regional highways,
including the San Diego Freeway (Interstate 405), MacArthur Boulevard,
Bristol Street, Bison Avenue, the proposed Corona del Mar Freeway (State
Highway 73), Ford Road, San Joaquin Hills Road and East Coast Highway
(State Highway 1).
The project area lies totally within the boundaries of the City of Newport
Beach. As shown in Exhibit 1, it is comprised of the southbound side of a
1.2 -mile stretch of Jamboree Road, between Ford Road and Eastbluff Drive
(North) .
IC. PROJECT OBJECTIVES
w
Jamboree Road is classified as a major (six -lane divided) arterial highway
on the City of Newport Beach Circulation Element Master Plan of Streets
and Highways (MPSH) and the Orange County Master Plan of Arterial Highways
(MPAH). The road is presently a four -lane divided roadway. A third
northbound lane, between Ford Road and Bison Avenue, is near completion.

Between Bison Avenue and Eastbluff Drive (North) a third northbound lane
' has been approved; completion of this portion is expected in 1983.1
The proposed project will widen the westerly (southbound) side of Jamboree
Road in conjunction with improvements to the easterly (northbound) side of
the roadway. As shown in the typical section in Exhibit 2, the widened
roadway will provide a third southbound travel lane, a raised curb and a
sidewalk -bike trail. Separate left -turn lanes, street lighting and
drainage system improvements are also included. The roadway improvements
will be constructed within the existing right -of -way up to the edge of the
Iexisting pavement.
The proposed project will ease congestion along this major north -south
route and will conform to the City of Newport Beach MPSH and the Orange
County MPAH.
D. PERMITS REQUIRED
The proposed project will not require any permits for construction.2 How-
ever, because of the study area's proximity to Upper Newport Bay, the City
of Newport Beach will need to coordinate closely with the State Water
Quality Control Board (Santa Ana Region) on the issue of erosion and
siltation control.3

II. LOCAL AND REGIONAL LAND USES RELATING TO THIS PROJECT
A. EXISTING LAND USE
Onsite Land Uses
The project area is comprised of the southbound Jamboree Road lanes and
westerly easement. The westerly easement is currently paved for use as an
emergency parking area only; it is not designed to withstand normal
vehicle travel.
Surrounding Land Use
As shown in Exhibit 1, the project site is located immediately west of the
Eastbluff residential community. Fifty -two single family residences have
lots which are directly adjacent to the project boundary. In general,
these properties range from above road -grade along the northern third of
the site, to at road -grade along the middle third of the site, to
below -grade along the southern third of the site (see Exhibit 1).
East of Jamboree Road, bounded by Ford Road, MacArthur Boulevard and Bison
Avenue, is the Aeronutronic Ford planned community (see Exhibit 1). The
existing Aeronutronic Ford office /industrial complex is generally in the
center of the planned community, with residential units to be built to the
north, south and east of the complex. Additional office /industrial
development within the Aeronutronic Ford complex is expected to continue
through 1992.1 A number of the residential units at the northeast corner
of Ford Road and Jamboree Road are nearing completion. The balance of the
site has been graded in preparation for construction. As part of this
planned community, a third northbound lane has been added to Jamboree Road
between Ford Road and Bison Avenue.
Within the triangle formed by Bison Avenue, Camelback Street and Jamboree
Road, land uses include a main post office, church, temple, Pacific
Telephone substation, and various professional offices. This area is
essentially built out.

North and east of Camelback Street and east of Jamboree Road is vacant
land which is designated as the North Ford planned community. Allowable
uses in this area include industrial, retail commercial and residential.
Anticipated date of completion for this development is 1983.1 As part of
this planned community, a third northbound lane is planned on the easterly
iside of Jamboree Road between Bison Avenue and Eastbluff Road (North).
South of the project area, Jamboree Road extends across San Joaquin Hills
Road and East Coast Highway (State Highway 1) to Bayside Drive, where it
becomes the only access road onto Balboa Island.

B. COMMITTED PROJECTS
The City requires all projects over 10,000 square feet of floor area to
comply with the City's Traffic Phasing Ordinance (TPO). When the required
approval has been received, the project is considered "committed" for
projecting future development in the City. Projects within Newport Beach
which are committed, but not yet constructed are listed below and their
corresponding locations are shown on Exhibit 3.

III. EXISTING CONDITIONS, IMPACTS AND MITIGATION MEASURES
A. ACOUSTIC ENVIRONMENT
1 A detailed noise impact study for the proposed project has been prepared
by BioAcoustical Engineering Corporation. This study is included in its
entirety in Appendix B and is summarized below.
Mitigation Measures
Existing Conditions
which
Existing noise levels in lots (primary outdoor living space) adjacent to
the
will mitigate noise levels at primary outdoor living spaces to
roadway are depicted in Exhibit 4. Several lots between Bison Avenue
and Eastbluff Drive North currently receive noise levels above 65 dB CNEL
which is the adopted City of Newport Beach standard for maximum noise
levels for outdoor residential living spaces. 65 CNEL is also the adopted
state and federal standard for maximum noise levels for outdoor residential
living spaces. The existing noise wall is also depicted on this exhibit,
Igenerally
parallel to the roadway.
Impacts
and implement
Projected noise levels with and without the project are shown in Exhibit
further
5. The results of the noise impact study show that minimal noise impact
can be expected from the proposed project. In 90 percent of the affected
houses along Jamboree Road, the change in noise impact is expected to be
I9
well below the threshold of human detectibility (i.e., in the range of 1
dB or less). In several homes, the impact may increase from 1.5 to 2.9
dB, which may approach the threshold of detectibility.
Mitigation Measures
1. The City of Newport Beach will offer to provide a noise barrier
which
will mitigate noise levels at primary outdoor living spaces to
65 dB
CNEL or lower.
In addition, the City will continue to work with adjacent
property
owners
as a part of the noise wall study program to develop
measures to
and implement
acceptable the community which will achieve
further
noise
reduction beyond the city, state and federal standards.

B. AIR QUALITY
Existing Conditions
The general air quality of the South Coast Air Basin, in which the City of
Newport Beach is located, is determined both by primary pollutants, such
as carbon monoxide, oxides of nitrogen, sulfur dioxide, particulates and
various hydrocarbons, added daily to the air mass, and by secondary pollu-
tants. With the passage of time, secondary pollutants are created in the
air mass by chemical and photochemical reactions (often involving primary
pollutants). Secondary pollutants, specifically oxidants (expressed as
ozone), represent the major air quality problem throughout the basin. The
air quality of the study area is determined by the primary pollutants
emitted locally, the existing regional ambient air quality, and the speci-
fic meteorological factors which influence the site.
Climate and Meteorology
Air quality in the vicinity of the study area benefits from the site's top-
ographic orientation and proximity to the coastline. Generally, winds
with 5 to 10- mile - per -hour speeds flow offshore during the nighttime hours
and are replaced by onshore breezes of the same magnitude by 10 a.m. Sum-
mer months usually include a northwesterly and southeasterly flow pattern
superimposed upon the daily sea breeze.
The climate in the study area is of the Mediterranean type (mild summers
and winters) with mean winter temperatures ranging from 45 degrees Fahren-
heit at night to 65 degrees Fahrenheit during the daytime, and mean summer
daytime temperatures ranging from 68 degrees to 75 degrees Fahrenheit.
Freezing temperatures occur infrequently along the coast.. The ocean's
influence dominates ambient wind and temperature conditions at the study
area.

Exposure to Air Pollutant Sources
The ambient air quality of a general area is partially determined by its
exposure to major sources of air pollutants such as power plants or indus-
trial sources. Stationary sources and mobile sources within a specific
area as well as in the general vicinity can also contribute to local pol-
lutant concentrations. Major point sources are defined as those generat-
ing a minimum of 100 tons per year of primary air pollutants.
The Southern California Edison fossil fuel power plant in Huntington Beach
is the major point source of air pollution located near the City of New-
port Beach. Because of the dominance of the land -sea wind pattern in the
area, emissions from this source tend to be carried inland or offshore,
rather than parallel to the coast: As a consequence, the power plant has
minimal influence on the air quality of the study area.
The primary source of air contaminants in the immediate vicinity of the
proposed project is vehicular exhaust from traffic on Jamboree Road and at
its intersections with Ford Road, Bison Avenue and Eastbluff Road (North).
Vehicle emissions primarily include carbon monoxide, oxides of nitrogen
and hydrocarbons.
Jamboree Road currently serves approximately 36,000 vehicles daily between
Ford Road and Bison Avenue, and 42,000 vehicles between Bison Avenue and
Eastbluff Drive (North). Air pollutant emissions generated by these
vehicles have been estimated to total 1.09 tons per day (see Table 1 for
comparison to the 1995 emission projections).
Ambient Air Quality
Ambient air quality is described in terms of compliance with state and
federal standards which have been adopted to protect public health with a
11
margin of safety (see Appendix C). In addition to ambient standards,
California has adopted "episode criteria" for oxidant, carbon monoxide,
sulfur dioxide, and particulate matter. Air pollution levels exceeding
the episode criteria represent short -term exposures at which public health
is actually threatened.
Ambient air quality is monitored by the South Coast Air Quality Management
District at a series of stations throughout the South Coast Air Basin.
The two stations closest to the study area are located inland of the site
in Los Alamitos (approximately 15 miles northwest) and Costa Mesa (approxi-
mately 5 miles northeast). Data for 1976 through 1980 from these stations
was used to determine the ambient air quality of the study area.
Pollutants which exceed state standards regularly (10 percent or more of
the days or months monitored) are oxidants, total suspended particulates
and lead particulates. Oxidants accumulate due to the daytime breezes
which carry nitrogen oxides and hydrocarbons into the area. Generally,
the offshore winds keep oxidant levels lower along the coast. Particulate
levels are most likely caused by a combination of natural and man -made
conditions. The total suspended particulate levels in the study area
constitute the major source of local air pollution.
Carbon monoxide and sulfur dioxide levels in Newport Beach have not exceed-
ed the state's one -hour standards during the past five years.l The state
nitrogen dioxide standards have been exceeded less than one percent of the
days monitored in 1976 through 1980 (as recorded at the Costa Mesa and /or
Los Alamitos stations).
Impacts
Roadway widening can affect local ambient air quality by altering the
established traffic flow patterns in the vicinity. Such alterations
1 State standards for 12 -hour CO concentrations have been exceeded at
the Costa Mesa station: 1976 -29 days; 1977 -5 days; 1978 -3 days;
1979 -5 days; 1980 -2 days.
12
1,
usually include changes in average route speeds, decreased delay
associated with signalized intersections, and reduced congestion.
The impact of this widening project on ambient air quality has been
assessed by comparing the air pollutant emission burden with and without
the widening for the year 1995. Additionally, maximum carbon monoxide
concentrations adjacent to the roadway have been estimated with and
without the widening to assess the impact of moving the southbound travel
lanes closer to adjacent residences.
Pollutant Burden Analysis
By 1995, Jamboree Road is expected to carry 48,000 average daily vehicles
between Ford Road and Bison Avenue, and 45,000 vehicles between Bison
Avenue and Eastbluff Drive (North). These volumes are expected whether or
not the Jamboree Road widening takes place. Table 1 shows the 0.44 tons
per day of air pollutant emissions generated by these traffic volumes. As
shown, motor vehicle emission controls in effect by 1995 will reduce air
pollutant emissions significantly along Jamboree Road despite the growth
in traffic volumes counterbalancing this effect. Clearly, the widening of
Jamboree Road will not adversely affect the quantity of air pollutants
emitted, but it will affect the spatial distribution of emissions, and
thereby the pollutant concentrations near the right -of -way.

The addition of a third southbound through lane along Jamboree Road will
reduce the amount of delay experienced by southbound vehicles at
signalized intersections. Although the magnitude of this delay reduction
will be relatively small (a few seconds per cycle), over the course of a
year.a cumulative reduction in idling vehicle emissions will result near
the affected intersections.
Average vehicle speeds along Jamboree Road presently range from 48 mph to
53 mph. Since the posted speed limit is 50 mph, these off -peak speeds
indicate a free - flowing condition. Periodic peak hour congestion is
observable currently; however, the addition of a southbound through lane
and median improvements should reduce congestion and improve traffic flow
by reducing forced merging maneuvers along Jamboree Road. The synchron-
ized traffic signals being planned will allow traffic on Jamboree Road to
traverse this segment at 45 mph, a speed indicative of relatively free
flow and low pollutant emissions (because of uniform speeds and continuity
in the traffic stream through coordinated signals).
Air Quality Projections
Estimates of future ambient air quality, with and without the widening of
Jamboree Road, allow the magnitude and extent of the impact associated
with locating a southbound travel lane closer to adjacent residences to be
defined. Because of the relative inertness of carbon monoxide in the
photochemical smog formation process and limitations on knowledge of the
dispersion of other vehicular emissions, carbon monoxide is the most
suitable tracer pollutant for microscale modeling. Secondary pollutants
are a regional or large -scale phenomenon which should be analyzed on a
mesoscale rather than a microscale basis.
Carbon monoxide concentrations have been estimated adjacent to the three
key intersections on Jamboree Road using the California Department of
Transportation Caline 3 line source dispersion model. Assumptions made
for the Caline 3 modeling appear in Appendix C and the results of the
calculations are summarized in Table 2. These exposures include future
14
i
ambient carbon monoxide concentrations of 8.45 parts per million (ppm) for
1 -hour averaging times and 6.22 ppm for 8 -hour averages, as outlined in
Appendix C.

Differences in the carbon monoxide exposure between widening Jamboree Road
or retaining it as it exists at present will not be significant. Both
receptors at grade or elevated at a distance of 150 feet from the Jamboree
Road centerline will be exposed to a 0.1 ppm increase in the carbon monox-
ide distance,
concentration. Beyond that elevated receptors will experi-
ence a minor decrease in exposure (.02 ppm over an 8 -hour averaging peri-
od) . Receptors at other distances will experience no measurable change in
exposure after the facility is widened. No significant adverse impacts
from the project on local or regional air quality have been determined.
Mitigation Measures
No mitigation measures are proposed.
C. AESTHETICS
Existing Conditions
The westerly side of Jamboree Road adjacent to the existing residential
community is extensively landscaped with trees, bushes and ground cover.
Vegetation along the easterly side is found in both open space, between
Camelback Street and Eastbluff Drive (North), and in occasional
landscaping. Dense established trees line the road between Bison Avenue
and Camelback Street. Mature trees and shrubs have recently been planted
'
along Jamboree Road near its intersection with Ford Road.
The character of land north and south of the Aeronutronic Ford facility on
the easterly side of Jamboree is undergoing change due to the construction
of a planned community development. Similar development is planned to

The noise barrier to be provided as mitigation for acoustical impacts will
also provide partial mitigation for aesthetic impacts. In situations
'
where units are below or at road - grade, an increased height noise barrier
will block line -of -site views of the roadway from most units at ground
level and possibly at second story levels. Units above road -grade may be
'
affected both adversely and beneficially. While views of the roadway may
be obscured by an increased barrier height, distant views also may be
interrupted. No significant adverse environmental impacts are anticipa-
ted.
'
Mitigation Measures
'
As part of the noise barrier proposed as mitigation for acoustical
impacts, the following aesthetic mitigation measures are proposed:
2. Landscaping and materials treatments will be included in the wall
design.
3. A plexiglass section may be used along the top of the noise barrier to
'
provide for distant views while mitigating acoustical impacts.

Residents of the area have expressed concern that provision of a sidewalk
along the roadside adjacent to residential properties may increase the
risk of burglaries or other crimes staged from the road corridor.
The proposed sidewalk would probably not increase the risk of burglaries
or other crimes staged from the roadway corridor due in large part to the
visibility of this area.l

rSurrounding Land Uses
' As shown in Exhibit 1, the residential community of Eastbluff is west of
the project area. Directly east, adjacent to Jamboree Road, are the
planned communities of "North Ford" and "Aeronutronic Ford ". At the
extreme northern boundary of the project site, the adjacent eastern
' property is zoned U, "Unclassified ". An unclassified district has no
precise zoning and requires a use permit for any type of land use.
Eastbluff Residential Area - Lying west of the project site, this
community is a mix of residential and commercial land uses and educational
facilities. The area immediately adjacent to Jamboree Road consists of
low density, single- family, detached dwelling units. Residential
construction within this development has been completed for a number of
years.

Fifty -two single family residences have lots which are directly adjacent
to the project boundary. The properties range from above -grade along the
'
northern third of the site, at -grade along the middle third of the site,
to below -grade along the southern third of the site.
'
Aeronutronic Ford Planned Community - Contiguous to the eastern boundary
'
of the study area is the + 215 -acre Aeronutronic Ford Planned Community
bounded by Jamboree Road, MacArthur Boulevard and Bison Avenue. The Gen-
'
eral Plan allows a mix of General Industry, Administrative, Professional
and Financial Commercial, and Residential uses within this planned
community.
Presently, Aeronutronic Ford contains more than 993,000 square feet of in-
dustrial research and development uses operated by the Ford Aerospace and
Communications Company. This existing development is located at the
center with residential units planned to the north, south and east.
Construction has begun on the residential phase of the project and a

the northeast corner of Ford Road and Jamboree Road are near completion.
' Approximately 102 acres remain undeveloped. Additional development is
limited to 360,000 square feet of office and industrial uses and 300
residential units. Construction of this phase is expected to continue
' through 1992.1
' North Ford Planned Community - North and east of Camelback Street and east
of Jamboree Road is the 68 -acre site of the North Ford Planned Community.
The General Plan designates a mix of General Industrial, Residential, Ad-

Section III, ACOUSTIC ENVIRONMENT. Noise levels will be reduced to City
' standards or below by use of a noise barrier.
Due to reduced congestion along Jamboree Road and stricter exhaust
emission standards in the future, the proposed road widening will not
significantly affect levels of vehicle exhaust (represented by carbon
' monoxide) adjacent to Jamboree Road. Air quality impacts are discussed
further in Section III, AIR QUALITY.
The proposed road widening will have a short -term visual impact during the

of the road next to the lot, the height of the noise barrier and the
height and density of landscaping. Impacts on aesthetics are discussed in
Section III, AESTHETICS.
tThe project will reduce use of residential streets (i.e., Eastbluff Drive)
as an alternate route during congested peak hours on Jamboree Road. In
addition, the raised median and curb will reduce the potential for cars
leaving the road and entering residential properties. Public safety

Impacts
The Jamboree Road widening project will provide sufficient roadway capa-
city to facilitate future traffic volumes, thus relieving severe traffic
congestion that will occur if the roadway is not widened. The widening
will also reduce the pressure to use Eastbluff Drive as an alternate
route.
Beneficial impacts will result in bicycle use through provision of a
southbound bike lane along the roadway margin.
The project is itself a mitigation measure. It will reduce congestion on
Jamboree Road to within acceptable limits. Mitigation of traffic - related
impacts is discussed in other sections of this document. No significant
adverse environmental effects are anticipated.

Jamboree Road traverses the easterly edge of the San Joaquin Hills in the
project area. Plio- Pleistocene sediments and Pleistocene terrace deposits
were exposed in cut slopes for grading the existing Jamboree Road.
The project area lies in a region having a potential for occurrence of
moderate to highly expansive soils. A portion of the project site also
lies in an area subject to severe erosion potential (south of Celtis
Place) . North of this street, the site is designated as having slight
erosion potential .1 However, erosion on the cut slope on the westerly
side of Jamboree Road has not been a problem.2
IImpacts
Earth materials beneath the roadway generally exhibit adequate characteris-
tics for road construction. Short -term increases in erosion will occur
Lduring road construction.
Because of their relative location and general characteristics, the soils
materials within the project area do not have special value as mineral re-
sources or borrow for fill. Thus, no significant loss of geological re-
source will result from construction of the project.
Proper road bed materials and construction practices will be used in the
widening project. In addition, erosion and siltation control measures
will be used during construction to minimize offsite sediment transport.

I. DRAINAGE
rExisting Conditions
The entrance of Aeronutronic Ford divides the pattern of drainage into
northerly and southerly directions from that apex of the roadway. Major
storm water collection points for runoff are at Ford Road, Bison Avenue,
and both ends of Eastbluff Drive. The southerly flowing runoff discharges
into the Big Canyon area and ultimately into Upper Newport Bay. Northerly
flowing runoff discharges directly into the San Diego Creek floodplain
which lies north of and adjacent to the project site, and also adjacent to
Upper Newport Bay.
Impacts
There will be no significant increase in the amount of storm runoff enter-
ing the drainage system and no significant changes will be made in the
overall drainage pattern. In addition, the project proposes to provide an
eighteen -inch storm drain and four catch basins that will connect to the
existing drainage system of the roadway.
While the amount of paved surface area will essentially remain the same, a
larger area of driving surface will incrementally add motor vehicle -rela-
ted pollutants into the surface runoff (i.e., leakage of fuel, lubricants,
particles worn off tires, clutch and brake linings, particulate exhaust
emissions, etc.).
As noted
above, a
short -term increase in silt and sediment production is
anticipated as a result
of construction.
Existing
drainage
facilities affected by construction activities will be
relocated
and /or
redesigned to compensate for the widened roadway.
Temporary
interim
drainage during construction will be tied in with an
effective
erosion
control plan.
t28
A
+ 0 Paved surfaces cleaned and maintained on a regular basis will minimize the
potential amount of pollutants entering San Diego Creek and Newport Bay.
Street surfaces and bicycle paths are cleaned on a regular basis using
mechanical sweepers.
The City has a program for cleaning out inlet structures and junction
chambers during the late summer or early fall. This minimizes the
potential adverse impact caused by the first big storm of the wet season
washing accumulated debris into the Bay.
An erosion control plan coordinated with the State Water Quality Control
Board (Santa Ana Region) will be implemented during construction to
minimize potential silt loss due to surface runoff. There will be no
significant adverse environmental effects.
Mitigation Measures
No mitigation measures are proposed.
J. UTILITIES
The
potential increased
amounts of pollutants from
vehicle traffic, on the
1
extra
travel lane will
be minor as a direct
result of the project.
Increased
traffic loads
along Jamboree Road will
occur whether Jamboree
Road
is widened or not.
The cumulative effect of
increased traffic versus
the
reduction in traffic
congestion due to widening
will tend to offset
the
incremental increase
in pollutants.
+ 0 Paved surfaces cleaned and maintained on a regular basis will minimize the
potential amount of pollutants entering San Diego Creek and Newport Bay.
Street surfaces and bicycle paths are cleaned on a regular basis using
mechanical sweepers.
The City has a program for cleaning out inlet structures and junction
chambers during the late summer or early fall. This minimizes the
potential adverse impact caused by the first big storm of the wet season
washing accumulated debris into the Bay.
An erosion control plan coordinated with the State Water Quality Control
Board (Santa Ana Region) will be implemented during construction to
minimize potential silt loss due to surface runoff. There will be no
significant adverse environmental effects.
As described previously, major storm water collection points for runoff
from the project area are at Ford Road, Bison Avenue, and at both ends of

intersection with Jamboree Road, also extending along the east side of
Jamboree Road to Camelback Street. A storm drain is also located along
the west side of Jamboree Road, approximately 200 feet from the inter-
section with Eastbluff Drive (North), turning and continuing along the
south side of Eastbluff Drive. This same storm drain connection extends
to the centerline of Jamboree.

Sewer
The project area lies within the jurisdiction of the County Sanitation
Districts of Orange County. Eight and ten -inch vitrified clay pipes lie
beneath both Ford and Jamboree Roads, extending along Jamboree Road to the
crest of the hill, and then turning east into the Aeronutronic Ford site.
A City of Newport Beach sewage pump station is located on Jamboree Road
near Carob Street.
Telephone
Pacific Telephone provides telephone service to the area. A multi- conduit
duct and buried cable lie at the intersection of Jamboree and Ford Roads.
A buried cable extends along the east side of Jamboree Road from Ford
IRoad,
terminating at the Aeronutronic Ford site. Two "c- cement" lines
begin at Ford Road, then follow Jamboree Road to Camelback Street where
they turn and follow the alignment of the latter street. Laterals extend
off these buried cables at Citrus Place, Chestnut Place and Cercis Place.

Natural Gas
Southern California Gas Company has an eight to twelve -inch high - pressure
line running from Ford Road northerly along Jamboree Road past Eastbluff
Drive (North) and four to eight -inch laterals at Ford Road and Bison
Avenue.
r
Electricity
ISouthern California Edison power distribution lines are located under-
ground from Bison Avenue past the northern boundary of the project site.
The underground lines consist of six ducts placed along the east side of
Jamboree Road, of which only two extend the full distance between Ford
Road and Bison Avenue. At Ford Road, ducts cross Jamboree Road. Buried
cables also cross Jamboree Road at Aralia and Basswood Streets. Two
vaults are located along Jamboree Road,
Overhead lines are supported by poles beginning at the east side of Jam-
, boree Road at Bison Avenue and continue north past the project boundaries.
These lines cross over Jamboree at several locations. A guy pole is
located on the west side of Jamboree Road at Eastbluff Drive (North).

IDrainage
The existing drainage system will be improved by the proposed project.
These improvements will include an eighteen -inch storm drain and six catch
basins which will connect to the existing system north and south of the
project area along Jamboree Road.

IExisting Conditions
Natural vegetation of the project area has been replaced by asphalt and
residential landscaping adjacent to roadway easements. Small trees and
ground cover have been planted in the center median.

Correspondingly, the area has little ability to support wildlife. Most
animals found near the project area are transient to and from adjacent
I
habitats.
North of the project area lies the San Diego Creek floodplain. The open
space region is considered by the State Department of Fish and Game to be
a valuable wildlife habitat.l Downstream from San Diego Creek is the Up-
per Newport Bay, providing important natural habitat for numerous fish and
wildlife species including several rare and /or endangered species of
birds.
Impacts
No significant impacts on existing fauna and flora within or adjacent to
the study area are anticipated. It is possible that some landscaping
adjacent to the roadway may be removed during construction.

PROJECT DESCRIPTION
A 1.2 -mile stretch of Jamboree Road, between Ford Road and Eastbluff Drive
(North) in Newport Beach, is proposed to be widened from a five -lane
divided road to a six -lane divided road. The roadway will be contained
within the existing paved right -of -way easement, and will include curb and
gutter, a 10 -foot wide sidewalk /bike trail and an emergency parking lane
all on the southbound side.
Intrinsic to the project is a noise attenuation study focusing on homes
west of and adjacent to the study area. A noise wall will be designed to
mitigate traffic noise impacts to these homes.
Major Local Issues
The initial study will be focused primarily on noise, air quality,
aesthetic and public safety impacts.

' Dear Mr. Talarico:
I am writing to you to express my concern about several issues discussed
at our recent meeting concerning the proposed widening of Jamboree Road
and its environmental impact on properties in Eastbluff. First, let me
say that I attended the meeting with a positive attitude and in a co- operative
mood. After all, the City of Newport had initiated this meeting to inform
' homeowners and solicit their opinions regarding the best ways to reduce
existing noise and minimize anticipated traffic noise resulting from the
road's expansion. I had attended the previous meeting at the Boys' Club
in Eastbluff (in June or July of 1980). Although the statements made by
city officials at that meeting were vague or tentative, they were made in
good faith at an early stage in the planning of the project. I attended both
meetings with an understandina of the need for the City of Newport to improve
' transportation in a rapidly growing area. As long as the City expressed its
willingness to respond to the needs of homeowners in the affected area,
I considered the expansion of Jamboree Road to be a fair and reasonable
project.
Unfortunately, .-jhat I learned at this second meeting has chanced my attitude
dramatically. I should add that my concern about noise from Jamboree traffic
' is expressed more for the sake of my neighbors than for myself and my family.
'::e live in the "green" area, and our lot and house are quite a distance below
the roadway. We have an eight -foot high (improved) concrete block wall, which
minimizes noise on the first floor and the backyard. ;e do experience some
traffic noise in our master bedroom (on the second floor, in the rear), but
that noise is only a minor irritant. On the other hand, many of our friends
and neighbors 14ve "n more directly exposed areas. We know that what is a minor
irritant to us must be an unbearable aggravation to others. Thus in the interests
of the Eastbluff community as well as in my own private interest, I am writing
to express concern about the following matters.
r1. Despite the concern expressed by city officials and consultants about traffic
noise from Jamboree Road, repeated reference was made to the "limited resources"
available for any noise - reduction plan. Early in the meeting you referred to
' the S 225,000 collected from various unnamed sources ( "interested parties ") to
support a noise- reduction program. Although other "contributions" night increase
this amount before actual construction of a noise -wall begins, the time -table
' you sketched out for the road widening suggests that $ 225,000 - S 250,000
will be just about all that is available for any improvements in the existing
barriers. As you noted, this would amount to "five or six thousand dollars worth
I
2.
'
of improvements" on each of the fifty -five properties affected (in fact, the
figure would be closer to $ 4,100 Needless to say, $225 250,000
per property). -
will not be sufficient to improve the existing wall in any manner other than
by adding concrete blocks. Piecing together several references you have made
in the past to a "six -foot concrete block wall," I would guess that the amount
of money collected would be just about appropriate for a two -foot increase in
the original four -foot walls. In short, our imaginative discussions of "concave
sound walls," "high- density noise baffles," and the like are mere exercises in
'
fantasy.
2. Acoustical engineers and other experts aside, I know that a six -foot high
concrete block wall will do little more than reduce the anticipated increase
in traffic noise back to the present noise level experienced by homeowners with
four
-foot walls at the current�fic density on Jamboree. Indeed, when Mr.
Smith discussed the anticipated "noise- reduction" program, he avoided quite
carefully the question of whether or not the planned wall improvement would
eventuate in a reduction of the existing noise level after the road had been
expanded and traffic increased.
3. The budgetary limitations (225 - 250,000) on any noise- reduction program
seem strangely at odds with the comments of Mr. Bixler and Mr. Brown regarding
the City, County, and Federal criteria for noise (and other environmental
issues) that would be used to judge the appropriateness of the plan to widen
Jamboree Road. Because the allocationsof highway construction funds from the
County are contingent upon the satisfaction of those requirements involved in
'
the EIR, then it would seem to follow that whatever improvements in the existing
wall (or its replacement) that might be deeme necessary to achieve a 65 dB
noise level in the backyard areas would have to be considered part of the total
cost for the widening of Jamboree Road. I understand, of course, that the
funds for road construction and the funds for noise- reduction would have to
be allocated by different governmental agencies, but the two expenses would
be integrally related and the full responsibility of the City of Newport.
'
Why, then, is the City collecting "funds" for this project from "interested"
parties (one must assume these parties to include those businesses with the
greatest stake in improved access along Jamboree)?
4. The answer to this question cannot be that the existing walls are on private
property. Proper noise -walls could be built beyond existing Eastbluff property
lines; the existing walls themselves (and the property on which they are built)
'
could be "donated" to the City on the promise of appropriate improvement.
5. You may recall that I posed this question about funding as the last question
in our general session. Your answer was quite interesting. Despite the
claims of others that the widening of Jamboree depends upon the satisfaction
of criteria established by the EPA and other related agencies, you claimed that
Jamboree could be widened without meeting such minimum requirements on the
'
grounds that such an improvement of the road without adequate improvement of
the noise -wall would be essential to the betterment of the entire community.
'
I assume that the procedure involved is analogous to what occurs in cases of
eminent domain where "just compensation" for an owner cannot be fully made.
That is, an individual or small group objects to an action /improvement that
is finally judged essential to the community as a whole and therefore warrants
the hardship experienced by that individual or small group.
I
I
' 3.
' You noted that the City of Newport would probably not take such action.
Anotherveading is that the City of Newport would not need to take such
action, should the homeowners in the affected area be convinced in advance
that the City had done "everything within its means" to reduce noise from
the expansion of Jamboree. Yet another reading is that the City could not
expand Jamboree Road, should its failure to comply with the criteri —'a
governing environmental impact be protested vigorously by the affected
' homeowners. Satisfied homeowners -- that is, homeowners convinced that
the City had conducted workshops, hired consultants, and thus tried to
solve the problem within the limits of a tight budget, etc. -- would file
their forms for the completion of the Environmental Impact Report, attend
' their workshops, and take what was offered with the familiar verbal
resignation: "Well, it's better than nothing" (a remark overheard at
least ten different times during our November 12 meeting).
' 6. Many specific questions (concerning on -site noise testing, anticipated
traffic density on Jamboree following expansion, the City's reasons for
expansion, and the like) received vague answers at our November 12 meeting.
Repeatedly we were told that "studies are not yet complete" or that "we will
discuss that at the next meeting." In February, you plan to make a formal
request to the County for highway construction funds, which you expect to
receive by July 1, 1982 for anticipated construction beginning in January of
1983. I find it difficult to believe that you have no specific information
regarding these matters (especially anticipated traffic density on Jamboree
' following expansion and according to annual increases) at this late date.
As for the noise ratings of specific sites, Mr. 6ixler made it clear that a
sound -meter provided an immediate (albeit unanalyzed) decibel figure. He
could not answer, however, questions concerning those on -site ratings.
' .;hat were the high and low sound -meter readings for the green, brown, and
orange areas? At what times were these measurements taken?
' I wish to protest, then, the budgetary limitations placed on the noise - reduction
program. The expansion of Jamboree Road should be contingent upon the construction
of a noise - barrier that will meet the minimum criteria acceptable by the County
and the federal government. If the cost of such construction of a noise- barrier
is too reat to be borne by the City at this time, then the expansion of amboree
must e e aye .
I

Sincerely,
/ John Rowe
Let me conclude this letter a bit more
gracefully. I raise
these questions and
'
objections in hopes that my fears are unfounded
and that the
City fully intends
to im rove the living conditions on the
affected properties.
If this can be
shore the case, then I express my
gratitude to you and
the others for
the public meetings you have conducted.
These questions and
others will be
answered in the completed Environmental
Impact Report, but I
would appreciate
any clarification you might give me and
my neighbors concerning
the issues
'
outlined above.

As Trustee I am the owner of 908 Celtis Place, Lot 10,
Tract 5018. My mother Catherine E. Argue resides at this
address. The subject property was purchased as a view
lot. In fact it has one of the better views in East Bluff.
Thus, a sound wall which would eliminate this view is not
desirable. Instead, it would be appreciated if the project
could be designed so as to attenuate the noise, but also
keep the view.
We would be interested in the receipt of further information
as it is available.
Thank you for your consideration of my view. (No pun intended!)
Sincerely,
Joh Argue

document prepared by the Office of Noise Control, entitled "Suggested
Contents of an Environmental Noise Study Report ...", which provides
some general guidelines as to what this office considers important in
Environmental Impact Reports and Statements.
The description of a noise barrier wall should be complete. That
is, its dimensions, weight, height, etc. should be described. In addi-
tion, your EIR should estimate the noise levels on residential properties
adjacent to and near Jamboree Road after completion of the wall.
If you have any questions, please feel free to contact Dr. Jerome
S. Lukas, Office of Noise Control, 2151 Berkeley Way, Room #516, Berkeley,

1 Because complaints about environmental noise are so frequent, the
Office of Noise Control believes that every project with a poten-
tial for increasing environmental noise levels should have a Noise
Study Report that assesses how noise levels resulting from the proj-
ect may affect people. The information contained in the Noise Study
Report should be summarized in the Environmental Impact Report or
Environmental Impact Statement, and the report kept on file by the
' lead agency for rcvicw by those with a specific interest in noise.
The attached is designed to help those who prepare Environmental
' Noise Study Reports and Environmental Impact Reports and reviewers
of Environmental Impact Reports. Because there are so many differ -
ent combinations of noise sources and receivers (people impacted by
1 those sources), it is virtually impossible to develop guidelines
that cover all situations. Nevertheless, the guidelines provided
should help to bring some consistency to the way noise information
is presented in environmental documents.

' SUGGESTED CONTENTS OF AN
ENVIRONMENTAL NOISE STUDY REPORT
I. A brief description of the project, especially in terms of its effect
1 -2-
on the noise environment.
II. Two scale
maps - one showing the existing setting and the proposed
project
with adjacent land uses, receptors, and noise sources iden-
tified,
and the second map showing the future condition (use a time
span of
no less than 10 years, unless the project's life span is less)
with the
proposed project and proposed land uses, receptors, and noise
sources
identified.
'
III. A
quantitative
description of the existing noise environment.
A. A noise survey should be undertaken and the details included in
'
the
report.
1.
The noise survey should encompass the proposed project area
and must include any noise sensitive receptors, both near and
far. The survey should establish the existing ambient noise
level and may then be used to evaluate compliance of the pro-
posed project with any applicable noise standards. The stand-
'
ards may be federal, state, or local. The rationale for the
selection of noise survey sites should be included in the
'
report.
2.
The survey should cover the time periods when the noise en-
environment would be affected by the proposed project.
3.
The survey should encompass enough days to be representative
of the existing "normal" noise environment. Discussion of
the similarity or dissimilarity of the noise environment dur-
'
ing the survey period with that during other times of year
should be included.
4.
For the time periods measured, the reported noise data should
include the Legq L1, L10, L50, L90, and identification of
typical noise levels emitted by existing sources. If day
and night measurements are made, report the Ldn also. Ldn
'
is approximately equal to CNEL; either descriptor may be
used.

5. Summarize the present environment by providing a noise contour
map showing lines of equal noise level in 5 dB - Ldn - steps,
extending down to Ldn = 55.
6. Identify the noise measurement equipment used in the survey by
manufacturer, type, and date of last calibration.
IV. A description of the future noise environment.
A. This section should discuss the future noise environment for each
project alternative. The scope of the analysis and the metrics
used will depend on the type of project, but as a minimum the fol-
lowing information must be given:
1. Discussion of the type of noise sources and their proximity
to potentially impacted areas.
2. Operations /activity data:
a. Average daily level of activity (traffic volume, flights
per day, hours on per day, etc.).
b. Distribution of activity over day and nighttime periods,
days of the week, and seasonal variations.
c. Composition of noise sources (% trucks, aircraft fleet
mix, machinery type, etc.).
d. Frequency spectrum of sources (1/3 octave data is pre-
ferable).
e. Any unusual characteristics of the sources (impulsive-
ness, tonality, etc.).
3. Method used to predict future levels.
a. Reference the prediction model used, if standard (e.g.,
FHWA -RD -77 -108, etc.).
b. If corrections to a standard model are made or empirical
modeling is used, state the procedure in detail.
c. Show typical levels (e.g., Ll, L10, etc.) at the re-
ceptors.
d. Give any other data yielded by the model you used.

4. Contours of future levels should be included (down to Ldn 55),
' and superimposed over projected population (receptor) densities.
V. Impact
A. Quantify anticipated changes in the noise environment by comparing
ambient information in III. with estimated source emissions in IV.
Evaluate the changes in light of applicable federal, state, and
local standards.
B. Discuss how this project relates to the Noise Element of the ap-
plicable general plan.
C. Discuss the anticipated effects of increased noise levels (speech
interference, sleep disturbance, disruption of wildlife habitat,
etc.).
VI. Mitigation
A. Discuss how adverse noise impacts can be mitigated, suggesting al-
ternative techniques for mitigation, their relative effectiveness,
' and feasibility of implementation. Provide a table listing the
most and least effective techniques. For this table, effective-
ness should be defined in terms of the number of people being ex-
' posed to noise at some given level.
B. Discuss any noise impacts that cannot be mitigated, and why miti-
gation is not feasible.

ASSESSMENT OF ENVIRONMENTAL
NOISE IMPACT FROM
JAMBOREE ROAD WIDENING
1 OVERVIEW
An engineering study has been performed to assess the City of Newport Beach's
proposed widening of Jamboree Road, between Ford Road and Eastbluff Drive
North. Traffic studies, topography data, on -site noise measurements, and
analysis were used to determine existing noise levels. Future traffic noise levels,
based on traffic flow projections, and proposed roadway plans were predicted
using the Federal Highway Administration's Highway Noise Prediction Model.
The results of the analysis show that the roadway widening, without mitigation
measures, could cause a noise increase as great as 3 dB CNEL. In over 90
percent of the cases, however, the increases are less than 1 dB CNEL and would
not be detectable by the human ear.
' INTRODUCTION
The City of Newport Beach has proposed to widen Jamboree Road between Ford
I Road and Eastbluff Drive (North) by adding a third lane of travel on the south
bound portion of the roadway. The addition of this lane will result in traffic
being some twelve feet closer to the adjacent Eastbluff residential development
bordering the roadway. This has the potential of increasing the noise in the
outdoor living space of each home adjacent to the roadway. The purpose of this
study is to examine this proposed widening of Jamboree, determine the traffic
noise impact for future years and develop a data base for the design of a noise
reduction barrier.
The basic plan for this noise impact evaluation is as follows: determine the
present noise level; project future noise levels with and without the road
widening project and then evaluate any difference in increases between the two
alternatives, i e., widening or no widening. The results of this study and some of
the underlying data and information are presented in the following sections.

u
Noise Model
The noise impacts at each of the fifty residences in Eastbluff that abut Jamboree
Road were calculated using the Federal Highway Administration's Highway Noise
Prediction Model, FHWA -RD -77 -108. This analytical computer model uses site
geometry, the number of vehicles passing each location, the vehicular speed, the
distance to each lane of the roadway, the reflectivity of the ground over which
the sound travels, and the degree of screening between the roadway and noise
sensitive use. The model is also sensitive to the change of traffic flow, and the
percentage mix of cars, and heavy trucks for each hour of the day.
' Input Parameters
' The accuracy of the Noise Prediction Model can be no better than the input data.
Therefore, an extensive amount of research was performed to develop the
information to "run" the model. Basically, there are two types of information
that are used: site geometry data; and traffic engineering data. The following
' paragraphs and tables will describe some of the research and document the
findings.

NOISE IMPACT ANALYSIS
The noise levels at any location adjacent to a roadway are dependent upon: the
number of vehicles per day using the road; the distribution of the flow over the
lanes; the traffic speed; the percentage of medium and heavy trucks; the hourly
use factor by vehicle type; the site geometry between the road and noise
sensitive locations; and a number of other factors.
Since there are some fifty -two potentially affected residential lots adjacent to
Jamboree Road, Figure 1, noise prediction analysis, calibrated by a limited
number of on -site noise measurements was used to economically perform the
noise evaluation.
On -Site Noise Measurements
Direct assessment of the existing noise impact was made in the backyard
(primary outdoor living space) of five separate Eastbluff residences using a
computer based robot noise monitor to measure and record the noise levels. At
the same time, robot traffic counters were used. to measure the vehicular flows
both north and southbound on Jamboree Road. A second noise measurement
program was performed at ten Eastbluff residences (including the five 24 -hour
sites). In this program, short -term noise measurements were made simul-
taneously with traffic classification counts, determining the vehicular mix of
cars, medium trucks and heavy trucks, and their influences on the acoustical
impact. The map in Figure 2 shows the locations of the noise and traffic
measurements. Figures 3 through 12 show the noise measurement locations
photographically. Tables I through V present the measured 24 -hour noise
impacts. Tables VI through XV present the results of the short term noise impact
measurements which were used to check traffic mix dependence.

Extensive traffic engineering studies were performed by Basmaciyan- Darnell,
Inc., traffic engineers, in the months of October and November, 1981, to
determine the existing traffic flow characteristics and project future conditions.
Some of the results of these studies used in preparing the input to noise model
are presented here to provide insight. Traffic counts were made over a one week
period on the month of October. Figure 13 shows the average daily traffic (ADT)
for the six roadway segments monitored. These ADT's were used for determining
the present traffic noise levels. These traffic counts, made on an hourly basis,
were then analyzed to determine the percentage of the ADT which flows on an
hour -by -hour basis. The results of this analysis is shown in Table XVI. During
the traffic measurement week, from 6 pm on 10/20/81 through 6 am on 10/21/81,
traffic counts were made of the numbers of medium (2 -axle) and heavy (3 or
more axle) trucks to determine the percentage of each in the traffic flow. This
data, combined with data from 4 April 1980 by Weston Pringle and Associates,
(traffic engineers) for the time period of 6 am to 6 pm on Jamboree Road, is also
displayed in Table XVI.
Radar speed studies are made on a regular basis by cities to determine
appropriate speed limits for roadways. The City of Newport Beach's traffic data
was reviewed and several studies were averaged together to obtain traffic speed
zones for both the north and south bound lanes. These data are displayed in
Figure 14.
Based on existing traffic flows, future regional growth, and the future City
roadway configurations, the traffic engineers have projected future ADT's by
roadway segment for Jamboree Road. The traffic engineers have projected that
there will be no significant differences in traffic speed or ADT on the south
bound lanes if the road widening does not occur. Figure 15 shows the predicted,
future average daily traffic flow rates for the project area.

Four sources of site geometry data were used to determine the relationship
between the roadway as it exists (and as it is proposed to be) and noise impacted
property:
1. Street Improvement Plans for Eastbluff Development —Tract Num-
bers 4705, 4892, 4893, and 5018, dated 9/27/63.
2. Jamboree Road Cross Sections, dated 7/6/76 (provided by City of
Newport Beach from an earlier study).
3. City of Newport Beach — Jamboree Road Aerial Photographs, dated
6/76, marked R- 5330 -5.
4. City of Newport Beach — Jamboree Road Plan and Profiles, Sheets 4,
5, 6, and 7 of 31, dated 1/28/81.
In addition, the civil engineering firm, RMG Engineering, was retained and all
noise monitored sites for this study were land surveyed to establish the heights
and location of all terrain features and man made structures between the
roadway and the noise measurement locations. New land cross - sections were
made and the old city - provided sections were verified for ten locations to
determine their probable validity. RMG Engineering indicated that the earlier
work was accurate for the locations checked.

Results of Noise Impact Analysis
The net change in traffic noise from adding a traffic lane to the south bound
lanes of Jamboree Road, between Ford Road and Eastbluff Drive North, varies
according to all of the input parameters, but is most heavily dependent upon
site geometry. There are essentially three conditions of site geometry that
1 exist in the proposed project area; houses above the roadway grade; houses at
the same height as the roadway grade; and houses below the roadway grade.
These three conditions are shown in Figure 16.
The change in noise impact at any residence, due to the road widening depends
upon the change in the relationship between the vehicular traffic and the
residence. Figure 17 is a simple illustration to show the effect of moving truck
traffic closer to a roadside home. The upper part of the figure shows the noise
path condition before road widening, where sound travels directly between the
diesel exhaust stack and the house. The lower part of the figure shows that,
I even though the trucks have moved closer with a road widening, the direct
sound from truck noise is above the roof line of the house.
The exact dimensions for each affected residential lot were used in the noise
model to develop the results shown in Table XVII. The last column of Table
XVII shows the noise increase due to road widening for future years traffic
levels. In all cases, the increase in noise from the widening is expected to be
minimal (90% of the lots receive less than 1 dB of change). The noise increase
on only two of the lots approaches the threshold of detectibility of 3 to 5 dB in
human ears. Subjectively, an increase of 10 dB would result in the perception
of a doubling of the noise impact.
Comparison of Measured and Calculated Noise Impacts
The purpose of the noise measurement program in this study was to provide a
basis for calibrating (i.e., adjusting) the noise impact prediction modeling to
reflect actual site conditions that might not be accurately depicted or
I accounted for correctly. Review of the five 24 -hour measured CNEL's showed a
high level of correlation between measured and predicted levels where expected
levels were high. But where the predicted noise levels were lower, the
measured noise levels were somewhat higher than would be expected. The
difference was resolved by examination of the noise contours for Orange
County's John Wayne Airport, Figure 18. Adding the approximate 55 dB CNEL
aircraft noise impact to the predicted roadway noise impact brings the
measured data to well within the expected accuracy of both community noise
measurement and prediction methodology, as is shown in Table XVIII.

CONCLUSION
The results of the noise impact study show that minimal noise impact can be
expected from the proposed Jamboree Road Widening Project. In 90 percent of
the possibly affected houses along Jamboree Road, the change in noise impact is
expected to be well below the threshold of human detectibility (i e., in the
range of 1 dB or less). In several homes, the impact may increase from 1.5 to
2.9 dB, which may approach the threshold of detectibility. If it is desired, these
impacts may easily be mitigated by increasing the height of the existing
property line barriers.

Caline 3 Assumptions and Results
1. Traffic Data was taken from the BDI study for the project.
2. Average Speeds of 50 m.p.h. were assumed for Jamboree Road, with
40 m.p.h. for Eastbluff Drive North and Ford Road, and 25 m.p.h.
for Bison Avenue and Eastbluff Drive.
3. Background Concentrations for carbon monoxide were derived from
ambient air quality data for 1980 taken at the Costa Mesa Monitoring
Station. The second highest hourly concentrations were used (i.e.,
11.80 ppm for the 8 -hour average, 16.0 ppm for the 1 -hour average,
and 10.3 ppm for the 12 -hour average). These levels were propor-
tionately reduced to reflect two trends anticipated by the year 1995.
First the reduction in emission rates between 1980 and 1995 resulting
from emission control technology was used to reduce the 1980 ambient
concentrations of carbon monoxide. Next the increase in the number
of in -use vehicles was accounted for by proportionately increasing
the ambient carbon monoxide concentrations to reflect a growth from
6.25 million vehicles in the South Coast Air Basin during 1995. This
growth amounts to a 3.5 percent increase annually per the CARD document
entitled "Procedure and Basis for Estimating On -Road Motor Vehicle
Emissions" dated January 1980. The resulting 1995 background or
ambient concentrations of carbon monoxide were found to be 8.45 ppm,
6.22 ppm and 5.43 ppm respectively for the 1 -hour, 8 -hour and 12 -hour
averaging periods.
4. Meteorological Conditions included worst -case assumptions of 2 m.p.h.
winds, stability classes of C, D and E and winds at 40 degrees with
respect to Jamboree Road as is typical for October conditions during
early morning hours when CO concentrations peak.
5. Highway Widths assumed were 33 meters for Jamboree without the widen-
ing, 40 meters with the widening and for Bison Avenue, 24 meters west
and 38 meters east of Jamboree. Eastbluff North was assumed to be
26 meters wide as was Eastbluff Drive opposite Ford Road. Ford Road
was evaluated with a 39 meter width. All widths include 3 extra meters
per side per the Caline 3 model directions.

6. Emission Factors from EMFAC 6c were used and provided for various
speeds by the O.C.E.M.A. from a computer run dated July 29, 1981.

SUBJECT: Traffic Engineering Services for Jamboree Road Noise
Wall Study
Dear Mr. Brown:
In accordance with your authorization, Basmaciyan- Darnell, Inc.
has conducted the collection of traffic data along Jamboree Road
between Eastbluff Drive and Eastbluff Drive /Ford Road. The
data collected includes 24 hour directional traffic volume counts
at three locations along Jamboree Road, vehicle classification
counts from 6:00 P.M. October 20, 1981, to 6:00 A.M. October 21,
1981, and vehicle classification counts for specific time
periods at specific addresses adjacent to Jamboree Road. Figure 1
is a location map generally depicting the data collection points.
24 Hour Volume Counts
Tables 1, 2 and 3 depict the results of the 24 hour daily
traffic volume counts collected along Jamboree Road. Each table
provides a summary of the hourly, directional total traffic
volume and the recommended average daily and hourly volumes to be
used in your analyses.
Table 1 summarizes the traffic volume data for Monday, October 9,
1981, through Friday, October 23, 1981. Figures 2 and 3 present
the recommended average daily volume for this portion of Jamboree
Road as an hourly percentage of the total volume by hour of day
and the hourly volume by hour of day, respectively.
Table 2 and Figures 4 and 5 represent the daily traffic volumes,
hourly traffic volumes as a percentage of the total, respectively,
between Eastbluff Drive and Bison Avenue for the five day period
October 19 through October 23, 1981.
Table 3 presents the daily traffic volume variations for Jamboree
Road between Bison Avenue and the entrance to Aeroneutronic Ford
(S /O Bison Avenue). The traffic volume data represents Wednesday
and Thursday, October 21 and 22, 1961. Figures 6 and 7 then
I
Mr. Mitch Brown
' November 11, 1981

' present the recommended average volume as a percentage of total
ADT and as total hourly volume by time of day, respectively.
Tables 4 and 5 present the results of the vehicle classification
counts conducted from 6:00 P.M. Wednesday, October 21, 1981,
to 6:00 A.M. Thursday, October 22, 1981.
Table 6 summarizes the vehicle classification counts collected by
BDI during the course of conducting the noise monitoring studies
along Jamboree Road on Wednesday, Ocotober 21, 1981.

January 5, 1982
Mfr. Fred Talarico
Environmental Coordinator
Newport Beach Planning Department
City Hall
3300 Newport Boulevard
Newport Beach, CA 92663
Dear Mr. Talarico:
C - C -fix)
In response to your recent request that we use photographs to
communicate our ideas and concerns related to the proposed
Jamboree Road street widening and sound barrier project, I
submit the attached materials. I am generally opposed to the
widening of Jamboree Road and am not convinced that it will
serve any useful purpose. As you will see from the comments
related to the attached photographs, I am vehemently opposed to
the placement of a sidewalk along the western edge of the road.
At the recent "Citizen's Workshop ", the response to my question
as to why a sidewalk was required was, and I paraphrase, "The
Public Works Department feels that if they do not build the
sidewalk in conjunction with the widening of the street, they
may not get another opportunity to do so." That response comes
very close to being an insult. I hope that is not an indication
of the depth of thought that goes into the decision to spend
taxpayer's money. The following are, in my opinion, the perti-
nent issues which need resolution relative to the construction
of the sidewalk:
• Is there adequate pedestrian traffic to justify a
sidewalk?
• Why is the sidewalk on the east side of the street not
adequate to serve pedestrian traffic?
• A sidewalk between the curb and the sound barrier wall
would butt directly against the wall and thereby
eliminate all existing or potential trees and shrub-
bery
• A sidewalk next to the wall would provide ready
access to our backyards by those inclined to trespass
• Trash, in the form of beer cans, coffee cups, and the
like, could be easily disposed of over the wall and
thereby litter our backyards
Mr. Fred Talarico
Environmental Coordinator
Newport Beach Planning Department
City Hall
January 5, 1982
Page 2.
• Elimination of trees and shrubs to accommodate a
sidewalk would destroy attractive natural beauty now
visable from our backyards and would create a bleak
and stark appearance along Jamboree Road
• What intelligent justification, if any, exists for
construction of the sidewalk?
The attached photographs further illustrate these comments and
depict the realities of the comments above.
I have included several photographs of a wall recently constructed
along Ford Road. Those appear to be expensive and in themselves,
attractive. They provide a stark appearance without mature
shrubs and trees in front of them. Since many of the homes
along Jamboree already have cinder block walls at the back of
their property, it would appear ludicrous to incur the cost of
demolishing the existing walls and building a new structure in
its place. The most cost effective solution, at least for
those homes at the southern end of Jamboree, would be to extend
the existing wall to a uniform six or seven foot height and
then, add white stuco and a red brick cap. Trimming of existing
trees and shrubs and clean up around their base without the
addition of a sidewalk would seem to be a very desireable and
attractive solution, as well as a cost effective one.
In summary, it is my sincere hope that this project will result
in:
• No sidewalk
• Retention of existing trees and shrubs
• Use of existing wall structure
• Minimum cost to taxpayers and developers.
Very truly yours,
Robert A. Bonsack

CITY COUNCIL AGENDA
ITEM N0.
u�C 14 1981
FROM: Public Works Department BY the CITY COUNCIL
CITY OF NYWP"T YLACH
SUBJECT: JAMBOREE ROAD WESTERLY SIDE, FROM FORD ROAD TO EASTBLUFF DRIVE NORTH
RECOMMENDATIONS:
1. Adopt a resolution requesting the County of Orange to include
the subject project in the fiscal year 1982 -83 Arterial Highway
Financing Program (AHFP).
Schedule a public hearing regarding the Initial Study and
Environmental Impact Report- Negative Declaration for the subject
project for January 11, 1982.
DISCUSSION:
Jamboree Road is classified as a major arterial highway (6 -lane
divided roadway) on the City of Newport Beach Circulation Element Master Plan
of Streets and Highways and the Orange County Master Plan of Arterial Highways.
The road is presently a 4 -lane divided roadway with ultimate improvements on
the easterly side of the roadway under construction as a condition of private
development. Widening of this segment will complete the improvements to
Jamboree Road from the San Diego Freeway to San Joaquin Hills Road.
The proposed project provides more efficient traffic flow by widen-
ing the westerly side of Jamboree Road in conjunction with improvements to
the easterly side of the roadway presently under construction. The widened
roadway will provide three travel lanes in each direction, raised median,
.separate left -turn lanes, a sidewalk -bike trail, street lighting, drainage
systems, noise wall, and signal modifications. See attached sketch for loca-
tion and limits of the work.
Shoulder pavement and an asphalt curb presently exist along the
west side of Jamboree Road within the project limits. The new curb and gutter
will be constructed at the same location as the existing asphalt curb, and the
shoulder pavement will be removed in order to construct the new street section.
All of the new roadway improvements will be constructed within existing right -
of -way.
In accordance with the California Environmental Quality Act (CEQA),
the State EIR Guidelines and City Policy, an Initial Study on the proposed
project has been prepared. It has been determined by the City's Environmental
Affairs Committee that the proposed project will not have any significant en-
vironmental impact, and a Negative Declaration has been prepared. The Negative
Declaration and Initial Study are attached. No action on the environmental
document is being requested at this time except to schedule a public.hearing
on it for January 11, 1981. This allows staff an opportunity to conduct the
third public workshop related to this project with the affected homeowners.

Subject: Jamboree Road Westerly Side, from Ford Road to Eastbluff Drive North
Page 2
The engineer's estimate for the project is $1,065,000
to finance the improvements as follows:
City Funds:
Gas Tax $ 62,000
Jamboree Road Noise Wall 198,000
Circulation and Transportation 460,000
County AHFP funds:
Total Project
It is proposed
$ 720,000
345,000
$1,065,000
The AHFP requires that an environmental document be submitted along
with all applications for funds. The Initial Study and Negative Declaration,
if accepted by the City Council,will meet their requirements.
AHFP also requires a resolution from the Council requesting the
amount of County funds needed for the project, and committing the City to
matching the County funds if the funds are granted to the City.
If this project is approved, construction could be completed during
the summer of 1983.

City Council Meeting January 11, 1982
Agenda Item No. D -3
CITY OF NEWPORT BEACH
December 16, 1981
TO: City Council
FROM: Planning Department By (COUNCIL
CITY �:: ORi BEACH
SUBJECT: Public Hearing for the acceptance of an Environmental Document for
the Widening of Jamboree Road and Improvement (Westerly from Ford
Road to Eastbluff Drive North).
Suggested Action
1. Hold hearing; close hearing; if desired, make the following
findings:
a.) That an Initial Study and Negative Declaration have been
prepared in compliance with the California Environmental
Quality Act (CEQA), the State Guidelines for Implementing
CEQA, and City Policy K -3, and that their contents have been
considered in the decision on this project.
b.) That based on the information contained in the Negative
Declaration, the project incorporates sufficient mitigation
measures to reduce potentially significant environmental
effects, and that the project will not result in significant
environmental impacts.
Background
At the December 14, 1981, City Council meeting the Council adopted Resolution
No. 11097 requesting the County of Orange to include Jamboree Road and
Improvements (Westerly from Ford Road to Eastbluff Drive North) in the fiscal
year 1982 -83 Arterial Highway Finance Program and set this public hearing to
consider the acceptance of the Initial Study and Negative declaration.
It would be appreciated if members of the City Council could bring their copy
of the Initial Study /Negative Declaration to the meeting. Should any member
of the City Council wish an additional copy please contact the Planning
Department at (640 - 2197). This information has been transmitted to each
property owner along Jamboree Road, the County of Orange and the Eastbluff
Homeowner's Association for their review.
TO. City Council -2.
Environmental Significance
In accordance with the California Environmental Quality Act (CEQA) , the State
EIR Guidelines and City Policy an Initial Study and Negative Declaration have
been prepared for the proposed project. The Initial Study was prepared by
Philips, Brandt and Reddick for the City of Newport Beach. Based upon the
contents of the Initial Study the City's Environmental Affairs Committee
prepared a conditional Negative Declaration for Council consideration. The
only major environmental issue identified in the Initial Study was noise
impacts, which are discussed in a separate section of this report.
Jamboree Road Widening
Jamboree Road is classified as a major (six -lane divided) arterial highway on
the City of Newport Beach Circulation Element Master Plan of Streets and
Highways (MPSH) and the Orange County Master Plan of Arterial Highways (MPAH).
The road is presently a four -lane divided roadway. A third northbound lane,
between Ford Road and Bison Avenue, is near completion.
Between Bison Avenue and Eastbluff Drive (North) a third northbound lane has
been approved; completion of this portion is expected in 1983.
The proposed project will widen the westerly (southbound) side of Jamboree
Road in conjunction with improvements to the easterly (northbound) side of the
roadway. A typical section is shown in Exhibit 2 of the Initial Study, the
widened roadway will provide a third southbound travel lane, a raised curb and
a sidewalk -bike trail. Separate left -turn lanes, street lighting and drainage
system improvements are also included. The roadway improvements will be
constructed within the existing right -of -way up to the edge of the existing
pavement.
Noise Wall Program
The City staff and consultants have been working directly with the
effected property owners along Jamboree Road through a series of workshop
meetings. The purpose of these meeting is to develop a clear public
understanding of the types, costs and effectiveness of various noise
mitigation potentials and to ultimately provide the City Council with
information on citizen concerns and desires related to a noise wall. Public
Work Shops have been held on Thursday, November 12, 1981, Tuesday, December 8,
1981 and Wednesday, January 6, 1982.
It is presently anticipated that at least one more public work shop with all
the affected property owners will be held in February 1962. A series of
smaller meetings is then anticipated between individual property owners and
staff or two /three neighbors and staff to work out specific concerns of each
individual homeowner. In most cases it will be necessary to work out separate
agreements with each individual homeowner to construct the noise wall. It is
presently anticipated by staff that all of the aforementioned can be worked
out by June, 1982 so that construction of the noise wall might coincide with
roadway improvements.

Noise Study
A detailed noise impact study for the highway widening project has been
prepared by BioAcoustical Engineering Corporation. This study is include in
its entirety in Appendix B of the Initial Study. Existing noise levels in
lots (primary outdoor living space) adjacent to the roadway are depicted in
Exhibit 4 of the initial Study. Several lots between Bison Avenue and
Eastbluff Drive North currently receive noise levels above 65 dB CNEL which is
the City of Newport Beach standard for maximum noise levels for outdoor
residential living spaces. 65 CNEL is also the adopted state and federal
standard for maximum noise levels for outdoor residential living spaces. The
existing wall is also depicted on this exhibit, generally parallel to the
roadway.
Projected noise levels with and without the project are shown in the Initial
Study in Exhibit 5. The results of the noise impact study show that minimal
noise impact can be expected from the proposed project. In 90 percent of the
affected houses along Jamboree Road, the change in noise impact is expected to
be well below the threshold of human detectability (i.e., in the range of 1 dB
or less). In several homes, the impact may increase from 1.5 to 2.9 dB, which
may approach the threshold of detectability. The following mitigation measure
has been specified related to the environmental concerns of the project.
"The City of Newport beach will offer to provide a noise barrier
which will mitigate noise levels at primary outdoor living spaces to
65 dB CNEL or lower."
In addition, the Staff has indicated that it will continue to work with
adjacent property owners as a part of the noise wall study program to develop
and implement measures acceptable to the community which will achieve further
noise reduction beyond the city, state and federal standards.

TO: City Council 4.
Sidewalk
The typical cross section planned for Jamboree Road includes 10 foot
sidewalks. During the public work shops held in November and December
residents from Eastbluff voiced their concern over the appearance of the
proposed noise wall in the areas where the 10 foot sidewalk would be directly
adjacent to the wall. City staff has considered their comments and proposes a
6 foot wide sidewalk with a 4 foot wide landscaped area adjacent to the wall.
