Summary
Existing Traffic Conditions
Future Traffic Impacts
This section summarizes the existing traffic conditions, future
traffic impacts, and future circulation recommendations.
The study area roadway links currently operate within acceptable
Levels of Service, except for the following study area roadway
links that operate at Level of Service F:
• Pacific Coast Highway, North City Limits to 1st Street
• Pacific Coast Highway, 1st Street to 5th Street
• Pacific Coast Highway, 5th Street to Marina Drive
• Pacific Coast Highway, Marina Drive to Bolsa Avenue
• Pacific Coast Highway, Bolsa Avenue to Seal Beach Boule-
vard
• Pacific Coast Highway, South of Seal Beach Boulevard
The study area intersections currently operate at Level of Ser-
vice D or better during the peak hours, except for the following
study area intersections that currently operate at Level of Service
E/F during the peak hours:
• Pacific Coast Highway (NS) at:
— 5th Street (EW)
• Seal Beach Boulevard (NS) at:
— I -405 Freeway NB Ramps (EW)
— I -405 Freeway SB Ramps (EW)
— Westminster Avenue (EW)
For Year 2025 traffic conditions, the roadway links in the vicin-
ity of the site are projected to operate within acceptable Levels
of Service, except for the following study area roadway links
that are projected to operate at Level of Service F:
• Pacific Coast Highway, North City Limits to 1st Street
• Pacific Coast Highway, 1st Street to 5th Street
• Pacific Coast Highway, 5th Street to Marina Drive
City of Seal Beach General Plan C -1
(12/03)
Circulation Element
• Pacific Coast Highway, Marina Drive to Bolsa Avenue
Pacific Coast Highway, Bolsa Avenue to Seal Beach Boule-
vard
• Pacific Coast Highway, South of Seal Beach Boulevard
For Year 2025 traffic conditions, the study area intersections are
projected to operate at Level of Service D or better during the
peak hours, except for the following study area intersections
which are projected to operate at Level of Service E/F during
the peak hours, without improvements:
Pacific Coast Highway (NS) at:
— 1st Street (EW)
— 5th Street (EW)
— Marina Drive (EW)
— Main Street / Bolsa Avenue (EW)
— Seal Beach Boulevard (EW)
• Seal Beach Boulevard (NS) at:
— I -405 Freeway NB Ramps (EW)
— I -405 Freeway SB Ramps (EW)
— Westminster Avenue (EW)
The study area intersections that are projected to operate worse
than Level of Service D (with improvements) are all located
along Pacific Coast Highway (SR 1). The relatively high levels of
traffic along this corridor are a direct result of increased devel-
opment outside of the City of Seal Beach and the congestion
along the San Diego (I -405) Freeway. The City of Seal Beach
General Plan Circulation Element and Orange County Master
Plan of Arterial Highways (MPAH) depict Pacific Coast High-
way (SR 1) as a Primary highway (4 lanes divided). As a Primary
highway (4 lanes divided), there is insufficient capacity along Pa-
cific Coast Highway (SR 1) to accommodate the existing as well
as future traffic volumes.
Future Circulation Recommendations
The following measures are recommended in the study area:
Amend the Orange County Master Plan of Arterial High-
ways (MPAH) to delete 1St Street as a Primary (100 foot
right -of -way) between Pacific Coast Highway (SR 1) and
Westminster Avenue.
City of Seal Beach General Plan C -2
(12/03)
Circulation Element
2. Amend the Orange County MPAH to delete the Edinger
Avenue extension as a Primary (100 foot right -of -way)
from its existing terminus to Pacific Coast Highway.
3. The following study area intersection improvements
should be included within the City of Seal Beach Capital
Improvement Program (CIP):
— Seal Beach Boulevard (NS) at Lampson Avenue
(EW)
— Additional Southbound Through Lane
— Seal Beach Boulevard (NS) at I -405 Freeway NB
Ramps (EW):
— Additional Northbound Through Lane — Bridge
Widening
— Additional Southbound Through Lane — Bridge
Widening
— Seal Beach Boulevard (NS) at I -405 Freeway SB
Ramps (EW):
— Additional Northbound Through Lane — Bridge
Widening
— Additional Southbound Left Turn Lane
— Additional Southbound Through Lane — Bridge
Widening
— Seal Beach Boulevard (NS) at Westminster Avenue
(EWD
— Northbound Left Turn Lane and Three Through
Lanes
— Additional Southbound Left Turn Lane
— Additional Eastbound Left Turn Lane
— Additional Eastbound Through Lane
— Additional Westbound Left Turn Lane
4. It should be noted that all of the improvements above
have previously been included as recommendations within
recent studies conducted in the study area. The City of
Seal Beach should periodically review traffic operations in
the study area to assure that the traffic operations are sat-
isfactory and environmental impacts are minimized
and /or mitigated.
City of Seal Beach General Plan C -3
(12/03)
Purpose and Scope
Statutory Requirements
Planning Areas
Government Code 565302(b) requires a Circulation Element in
all city general plans, as follows:
"...a circulation element consisting of the general location
and extent of existing and proposed major thoroughfares,
transportation routes, terminals, and other local public utili-
ties and facilities, all correlated with the land use element of
the plan."
The Circulation Element of the City of Seal Beach General Plan
serves as the City's primary guide for transportation planning.
The Circulation Element is concerned with accommodating the
transportation needs of those living, working, and visiting the
City. Its objective is to articulate the City's vision and plans for
the ongoing development and maintenance of a comprehensive
circulation network that will efficiently move people and goods
throughout the City of Seal Beach and the surrounding region.
The Circulation Element focuses on roadways and other trans-
portation modes, including public transit, railroads, and bicycle
paths, that provide a full range of travel options. Also included
is an assessment of the City's current roadway system and rec-
ommendations for the improvements necessary to maintain ac-
ceptable Levels of Service on this system throughout the Year
2025.
The City of Seal Beach (see Circulation - Figure 1) has been di-
vided into five planning areas, as follows (see Circulation - Fig-
ure 2):
• Planning Area 1 - Old Town, Surfside
• Planning Area 2 - Hellman Ranch, Boeing, The Hill
• Planning Area 3 - Leisure World
• Planning Area 4 - College Park, Rossmoor, Bixby
• Planning Area 5 - U.S. Naval Weapons Station

Circulation Element
Related Plans and Programs
Several transportation plans prepared by the County of Orange
focus on the regional transportation system. Strategies to handle
anticipated traffic levels from future development are discussed.
Plans and programs related to the Circulation Element include
the following:
• County of Orange Master Plan of Highways (MPAH)
The County of Orange Master Plan of Arterial Highways
(MPAH) forms a part of the Orange County General Plan
and designates the arterial system in the Circulation Ele-
ment of the General Plan. Defined according to specific ar-
terial functional classifications, the MPAH defines the in-
tended future roadway system for the County. Cities within
the County are expected to achieve consistency with the
MPAH in individual General Plan circulation elements.
The Seal Beach Circulation Element proposes no further
extension to First Street as a Primary Highway and no ex-
tension of Edinger Avenue. To implement this change to
the MPAH, approval from the Orange County Transporta-
tion Authority (OCTA) is required.
• County of Orange Congestion Management Plan (CMP)
Urbanized areas such as Orange County are required to
adopt a Congestion Management Plan (CMP). The goals of
the CMP are to reduce traffic congestion and to provide a
mechanism for coordinating land use development and
transportation improvement decisions. For the most part,
the Orange County CMP is a composite of local agency
submittals in which each local jurisdiction develops the re-
quired data in accordance with the guidelines established by
the Orange County Transportation Authority (OCTA). The
OCTA compiles the data and submits the results to the
Southern California Association of Governments (SCAG)
for a finding of regional consistency. Pacific Coast High-
way is the only road in Seal Beach that is a component of
the Congestion Management Plan system.
• County of Orange Growth Management Plan (Measure M)
Measure M, the revised Traffic Improvement and Growth
Management Ordinance, authorized by the imposition of a
one -half percent sales tax to fund needed transportation
improvements. To be eligible to receive Measure M funds,
local jurisdictions must satisfy a variety of requirements as
City of Seal Beach General Plan C -7
(12/03)
Circulation Element
set out in the Orange County Local Transportation Au-
thority (LTA) Ordinance No. 2. LTA Ordinance No. 2 re-
quires local jurisdictions to adopt a traffic circulation plan
consistent with the MPAH, adopt and adequately fund a
local transportation fee program, satisfy maintenance re-
quirements, adopt a Growth Management Element, and
adopt a seven -year capital improvement program that in-
cludes all transportation projects funded either partially or
fully by Measure M funds.
• County of Orange Master Plan of Countywide Bikeways
Also part of the County of Orange General Plan, the Mas-
ter Plan of Countywide Bikeways designates various classes
of bike routes throughout the County. One of the primary
considerations of this plan is to provide continuity
throughout the County and to provide consistency between
countywide and local jurisdiction bikeway plans. The Circu-
lation Element contains a bikeway plan that utilizes the
countywide classification system and links to County
routes.

Existing Traffic Conditions
The traffic conditions as they exist today are discussed below
and illustrated on Circulation - Figure 3 through Circulation -
Figure 1.
Existing Travel Lanes and Intersection Controls
Circulation - Figure 3through Circulation - Figure 12 identify
the existing roadway conditions for arterials within the City of
Seal Beach. The number of through lanes for existing roadways,
by Planning Area, are illustrated on Circulation - Figure 3
through Circulation - Figure 7. The existing intersection con-
trols are identified by Planning Area on Circulation - Figure
8through Circulation - Figure 12.
Existing Average Daily Traffic (ADT) Volumes
All tables and figures in the Circulation Element reflect informa-
tion obtained by conducting a detailed traffic analysis prepared
by Kunzman Associates in March 2003 for the City. Where daily
traffic counts were not available and where peak hour counts
were available, daily traffic counts were estimated by Kunzman
Associates from the peak hour counts.
Existing Volume to Capacity Ratios
Roadway capacity is generally defined as the number of vehicles
that can be reasonably expected to pass over a given section of
road in a given time period. Congestion, high accident rates, the
quality of traffic flow (Level of Service), and environmental ac-
ceptability all come into play in defining a particular roadway's
effective capacity. It is possible to identify maximum desirable
volumes for typical roadway types based on the number of
roadway travel lanes. These daily volumes reflect estimates of
the amount of daily traffic that will result in peak hour traffic
volumes equal to the maximum desirable capacity of each road-
way type. In the City of Seal Beach, Level of Service D is the
minimum acceptable condition that should be maintained along
roadway segments.

Circulation Element
By dividing existing ADT volumes by the daily roadway capaci-
ties listed in Circulation - Table 2, existing volume -to- capacity
ratios have been calculated and are shown in Circulation - Table
1. As may be seen in Circulation - Table 1, the study area road-
way links currently operate within acceptable Levels of Service,
except for the following study area roadway links that operate at
Level of Service F:
• Pacific Coast Highway, North City Limits to 1st Street
• Pacific Coast Highway, 1St Street to 5th Street
• Pacific Coast Highway, 5th Street to Marina Drive
• Pacific Coast Highway, Marina Drive to Bolsa Avenue
• Pacific Coast Highway, Bolsa Avenue to Seal Beach Boule-
vard
• Pacific Coast Highway, South of Seal Beach Boulevard
Existing Intersection Capacity Utilization
The technique used to assess the operation of an intersection is
known as Intersection Capacity Utilization (ICU). To calculate
an ICU value, the volume of traffic using the intersection is
compared with the capacity of the intersection. An ICU value is
usually expressed as a percent. The percent represents that por-
tion of the hour required to provide sufficient capacity to ac-
commodate all intersection traffic if all approaches operate at
capacity.
The ICUs for the existing traffic conditions have been calcu-
lated and are shown in Circulation - Table 3. Existing ICU val-
ues are based upon manual morning and evening peak hour
turning movement counts made for the City of Seal Beach and
Kunzman Associates in January /March /June/ September/ No-
vember, 2002 (see Circulation - Figure 13 through Circulation -
Figure 14). Traffic count worksheets are provided in Appendix
B of the Circulation Analysis.
There are two peak hours in a weekday. The morning peak hour
is between 7:00 a.m. and 9:00 a.m., and the evening peak hour is
between 4:00 p.m. and 6:00 p.m. The actual peak hour within
the two -hour interval is the four consecutive 15- minute periods
with the highest total volume when all movements are added
together. Thus, the evening peak hour at one intersection may
be 4:45 p.m. to 5:45 p.m. if those four consecutive 15- minute
periods have the highest combined volume.

When a right turn lane is designated, the lane can either be striped or unstriped. To function as a right turn lane, there must be sufficient
width for right turning vehicles outside the through lanes.

ICU-LOS =Intersection Capacity Utilization -Level of Service
TS= traffic signal
CSS =cross street stop
City of Seal Beach General Plan C -12
(12/03)
Circulation Element
The technique used to calculate Intersection Capacity Utilization
(ICU) is as follows. Lane capacity is 1,700 vehicles per lane per
hour of green time for through and turn lanes. A total yellow
clearance time of 5% is added. In the City of Seal Beach, Level
of Service D is the minimum acceptable condition that should
be maintained during the peak hours.
The study area intersections currently operate at Level of Ser-
vice D or better during the peak hours, except for the following
study area intersections that currently operate at Level of Service
E/F during the peak hours:
• Pacific Coast Highway (NS) at:
— 5th Street (EW)
• Seal Beach Boulevard (NS) at:
— I -405 Freeway NB Ramps (EW)
— I -405 Freeway SB Ramps (EW)
— Westminster Avenue (EW)
Existing ICU worksheets are provided in Appendix C of the
Traffic Analysis.
Comparison of volume to capacity ratios and corresponding
Level of Service, and peak hour Intersection Capacity Utilization
and corresponding Level of Service reveals significant differ-
ences. The differences between link volume to capacity ratios
and peak hour ICU values is particularly pronounced when
cross traffic is light. Volume to capacity ratios assume that all
cross streets require 50% of the time to satisfy their demand,
and assume that the subject street has 50% of the time available
to it. The link volume to capacity ratios are a generalized indica-
tor, while peak hour ICU actually represents what can be ex-
pected in the peak hour at intersections. Of the two indicators,
the peak hour ICU value and corresponding LOS is by far the
best measure of roadway performance.
Existing Master Plan of Arterial Highways
Circulation - Figure 15 exhibits the City of Seal Beach General
Plan Circulation Element. Existing roadways and future road-
ways are included in the Circulation Element of the General
Plan and are graphically depicted on Circulation - Figure 15.
This figure shows the nature and extent of arterial highways that
are needed to serve adequately the ultimate development de-
picted by the Land Use Element of the General Plan.

Existing and Proposed Bicycle Facilities
Existing Transit Service
The bicycle facilities within the study area are depicted on
Circulation - Figure 16 through Circulation - Figure 20 by Plan-
ning Area. The City of Seal Beach has established the following
three classifications of bikeways that generally correspond with
the Orange County Transportation Authority (OCTA) bikeway
classifications:
Class I Bikeway — Provides for bicycle travel on a right -of-
way completely separated from the street.
Class II Bikeway — Provides for a striped lane for one -way
travel within the street right -of -way.
• Class III Bikeway — Provides for on -road, signed only bike-
way-
The City of Seal Beach also has a Class III Bikeway designation.
Class III Bikeways provide for on -road, signed only bikeways.
These are special locations and are not included on the bike trail
map.
The study area is currently served by Orange County Transpor-
tation Authority (OCTA) Routes 1, 21, 42, 60, 70,164, and 701.
In addition, Long Beach Transit Route 131 serves the study
area. Circulation - Figure 21 through Circulation - Figure 1 illus-
trate the existing transit routes by Planning Area.
• Route 1 currently provides service along Pacific Coast
Highway (SR -1).
• Route 21 currently provides service along Bolsa Chica Street
and Edinger Avenue.
• Route 42 currently provides service along Seal Beach
Boulevard, Electric Avenue, Main Street, Bolsa Avenue,
Balboa Drive, and Pacific Coast Highway (SR -1).
• Route 60 currently provides service along Westminster
Avenue.
• Route 70 currently provides service along Bolsa Chica Street
and Edinger Avenue.
• Route 131 currently provides service along Pacific Coast
Highway (SR -1), Main Street, Electric Avenue, and 5th
Street.

Existing Rail Service
Existing Truck Routes
• Route 164 currently provides service along Lampson Ave-
nue, Seal Beach Boulevard, and Golden Rain Road.
• Route 211 currently provides service along Lampson Ave-
nue and Seal Beach Boulevard.
• Route 701 currently provides service along Lampson Ave-
nue and Seal Beach Boulevard.
A park -and -ride facility that allows commuters to meet and park
their personal vehicles at one location and utilize carpools, van -
pools, or commuter bus service is located along Lampson Ave-
nue (Planning Area 4).
The U.S. Navy currently operates rail service generally within
Planning Area 5 in the U.S. Naval Weapons Station.
Designated truck routes in the City of Seal Beach are illustrated
on Circulation - Figure 26.

Year 2025 Traffic Conditions
Method of Projection
In this section, Year 2025 traffic conditions reflecting ultimate
buildout of the existing General Plan are discussed. Circulation -
Figure land Circulation - Figure 28 illustrate the Year 2025 traf-
fic conditions.
The Year 2025 ADT volumes have been obtained from the
subregional travel demand model currently being used for long -
range planning in the City of Seal Beach. This model is com-
monly referred to as the Orange County Traffic Analysis Model
(OCTAM 3.1). The data source is OCP -2000 (version 020801).
Year 2025 peak hour forecasts have been developed from the
OCTAM using accepted procedures for model forecast refine-
ment and smoothing.
The ADT volumes, particularly on the regional facilities, reflect
the areawide growth anticipated between now and Year 2025.
The Year 2025 peak hour forecasts were refined using the daily
forecasts, along with existing peak hour traffic count data col-
lected at each analysis location. The traffic model zone structure
is not designed to provide accurate turning movements along ar-
terial roadways unless refinement and reasonableness checking
is performed.
The initial estimate of the Year 2025 peak hour turning move-
ments has, therefore, been reviewed for reasonableness. The
reasonableness checks performed include review of flow con-
servation in addition to comparisons to the existing actual
counted volume and the overall relationship between the fore-
cast peak hour volume and daily volume on each individual in-
tersection leg. Where necessary, the initial raw model estimates
were adjusted to achieve flow conservation, reasonable growth,
acceptable relationships between the peak hour and daily traffic
volume forecasts, and reasonable diversion between parallel
routes.

Year 2025 Average Daily Traffic (ADT) Volumes
For Year 2025 traffic conditions, through traffic for the study
area has been determined by utilizing the OCTAM described
above. Year 2025 ADT volumes in the study area are depicted
in Circulation - Table 1.
Year 2025 Volume to Capacity Ratios
For Year 2025 traffic conditions, volume to capacity ratios have
been calculated and are shown in Circulation - Table 1. Volume
to capacity ratios are based on City of Seal Beach roadway ca-
pacities depicted in Circulation - Table 2 - Roadway Capacities.
For Year 2025 traffic conditions, the roadway links in the vicin-
ity of the site are projected to operate within acceptable Levels
of Service, except for the following study area roadway links
that are projected to operate at Level of Service F:
• Pacific Coast Highway, North City Limits to 1st Street
• Pacific Coast Highway, 1st Street to 5th Street
• Pacific Coast Highway, 5th Street to Marina Drive
• Pacific Coast Highway, Marina Drive to Bolsa Avenue
• Pacific Coast Highway, Bolsa Avenue to Seal Beach Boule-
vard
• Pacific Coast Highway, South of Seal Beach Boulevard
Year 2025 Intersection Capacity Utilization (ICU)
The technique used to assess the operation of an intersection is
known as Intersection Capacity Utilization (ICU). To calculate
an ICU value, the volume of traffic using the intersection is
compared with the capacity of the intersection. An ICU value is
usually expressed as a percent. The percent represents that por-
tion of the hour required to provide sufficient capacity to ac-
commodate all intersection traffic if all approaches operate at
capacity.
The ICUs for the Year 2025 traffic conditions have been calcu-
lated and are shown in Circulation - Table 5. Year 2025 morning
and evening peak hour turning movement volumes are shown
on Circulation - Figure 1 and Circulation - Figure 28.

For Year 2025 traffic conditions, the study area intersections are
projected to operate at Level of Service D or better during the
peak hours, except for the following study area intersections,
which are projected to operate at Level of Service E/F during
the peak hours, without improvements:
• Pacific Coast Highway (NS) at:
• 1st Street (EW)
• 5th Street (EW)
• Marina Drive (EW)
• Main Street /Bolsa Avenue (EW)
• Seal Beach Boulevard (EW)
• Seal Beach Boulevard (NS) at:
• I -405 Freeway NB Ramps (EW)
• I -405 Freeway SB Ramps (EW)
• Westminster Avenue (EW)
The following study area intersection improvements should be
included within the City of Seal Beach Capital Improvement
Program (CIP):
• Seal Beach Boulevard (NS) at Lampson Avenue (EW)
— Additional Southbound Through Lane
• Seal Beach Boulevard (NS) at I -405 Freeway NB Ramps

The study area intersections that are projected to operate at
worse than Level of Service D (with improvements) are all lo-
cated along Pacific Coast Highway (SR -1). The relatively high
levels of traffic along this corridor are a direct result of increased
development outside the City of Seal Beach and the congestion
along the I -405 Freeway. The City of Seal Beach General Plan
Circulation Element and the Orange County Master Plan of Ar-
terial Highways (MPAH) depict Pacific Coast Highway (SR -1) as
a Primary highway (4 lanes divided). As a Primary highway (4
lanes divided), there is insufficient capacity along Pacific Coast
Highway (SR -1) to accommodate the existing as well as future
traffic volumes.

Goals, Objectives, and Policies
General
Goal:
The following goals, objectives, and policies form the basis for
providing a circulation system that adequately serves the devel-
opment intensity anticipated in the Land Use Element. The goal
for the Circulation Element expresses the importance of the cir-
culation system to the quality of life and the vitality of the local
economy, and sets a high standard for its performance.
Provide and maintain a comprehensive circulation system that
facilitates the efficient movement of people and goods through-
out the City and near open space habitats for wildlife, while
minimizing environmental impacts (including air, light, and
noise pollution).
Objective:
Ensure that the circulation system is in balance with the City's
Land Use Element.
Policies:
Monitor and participate in applicable county, regional,
state, and federal transportation plans and proposals.
Maintain compliance with the County's Congestion Man-
agement Plan (CMP) and Growth Management Plan
(GMP).
Review implementation programs that coordinate the
transportation needs and requirements of the City with
those of other public agencies in order to ensure that the
overall circulation plan of the City is effective, efficient, and
safe.
Develop and implement an annual Capital Improvement
Program (CIP) for transportation system projects.
City of Seal Beach General Plan C -48
(12/03)
Circulation Element
Cam;
Objective:
Provide adequate capacity for the City's circulation needs while
minimizing negative impacts, including environmental impacts
needing mitigation.
Policies:
Maintain circulation system standards for roadways and in-
tersection classifications, right -of -way width, pavement
width, design speed, capacity, maximum grades, and associ-
ated features such as medians and bicycle lanes.
Develop a circulation system that enhances environmental
amenities and scenic areas.
Maintain primary truck routes that sustain an effective
transport of commodities while minimizing the negative
impacts on local circulation and on noise - sensitive land
uses.
Utilize Caltrans and City design criteria for any future truck
routes within the City.
Objective:
Provide a circulation /transportation system that enhances and
minimizes response time needed for emergency vehicles.
Policies:
Ensure that primary and secondary roadways are able to be
used for evacuating persons from their homes during
emergency conditions or for ingress when emergency re-
sponse units are needed.
Create attractive circulation corridors to enhance the City's im-
age.
Objective:
Preserve rights -of -way along circulation corridors to provide
landscaped parkways and setback areas.
City of Seal Beach General Plan C -49
(12/03)
Circulation Element
Level of Service
Goal:
Policies:
Enhance street design standards to promote attractive cir-
culation corridors.
Coordinate a signage program to direct motorists to City
activity centers from freeways.
Provide landscaped medians on major arterials, when ap-
propriate.
Provide upkeep of the City's streets and parkways based
upon an established maintenance schedule.
Promote the undergrounding of utilities along travel routes.
Support the protection and enhancement of view corridors.
Provide a circulation system that supports existing, approved,
and planned land uses throughout the City while maintaining a
desired Level of Service on all streets and at all intersections.
Objective:
Comply with adopted performance standards for acceptable
Levels of Service.
Policies:
Maintain a citywide Level of Service (LOS) not exceeding
LOS D for roadway segments and intersections during the
peak hours. The study area intersections that are projected
to operate at worse than Level of Service D (with im-
provements) are all located along Pacific Coast Highway
(SR -1). The relatively high levels of traffic along this corri-
dor are a direct result of increased development outside of
the City of Seal Beach and the congestion along the I -405
Freeway. The City of Seal Beach General Plan Circulation
Element and the Orange County Master Plan of Arterial
Highways (MPAH) depict Pacific Coast Highway (SR -1) as
a Primary highway (4 lanes divided). As a Primary highway
(4 lanes divided), there is insufficient capacity along Pacific

Limit the number of driveways on arterial streets to reduce
vehicular conflict and facilitate traffic flow.
Require new development to install traffic signals at inter-
sections on arterials that, based on individual study, are
shown to satisfy traffic signal warrants.
Promote the use of traffic signal coordination within the
City and with adjacent jurisdictions.
Support development of regional transportation facilities that
ensure the safe and efficient movement of people and goods
from within the City to areas outside its boundaries, and that ac-
commodate the regional travel demands of developing areas
outside the City, while minimizing air and noise pollution and
other environmental impacts.
