APPROVAL OF ORDINANCE RESTRICTING NEW
DEVELOPMENT ALONG CHARLESTON-ARASTRADERO ROAD
CORRIDOR PENDING IMPLEMENTATION OF TRAFFIC PLAN
RECOMMENDATION
Staff recommends that Council adopt the attached ordinance (Attachment A) restricting
new development along the Charleston-Arastradero Road corridor for a limited period of
time, pending implementation of the Charleston-Arastradero Road Corridor Traffic
Management and Safety Plan (Traffic Plan).
BACKGROUND
The Charleston-Arastradero Road corridor is a major school commute corridor in Palo
Alto. From Hoover Elementary and JLS Middle Schools on Charleston, to Gunn High
and the new Terman Middle Schools on Arastradero, school commuters of all ages
commute along and across these major streets. The predominant land use on both streets
is residential and both are classified as residential arterial streets in the 1998-2010 Palo
Alto Comprehensive Plan. An advisory panel of neighborhood associations and school
PTA traffic safety representatives has recommended that the Transportation Division
include each street as a school commute corridor, part of a citywide network of streets
important to school commuters. This proposal will be discussed at a meeting of the
City/School Traffic Safety Committee on April 24 and at the Planning and Transportation
Commission meeting of May 14.
A traffic safety and management study of Charleston Road, completed in December
2000, identified a number of deficiencies in pedestrian and bicycle facilities (Attachment
C, CMR:188:0!). In addition, concerns about travel safety and residential quality of life
have been expressed to Transportation Division staff at neighborhood association
meetings along the Charleston-Arastradero Road corridor, and by personal
communications from residents and parents of students commuting along or across the
corridor.
CMR:237:03 Page ! of 5
A number of transportation initiatives have been undertaken to enhance safety for school
commuters and other road users on each street. The bicycle lane gap in the vicinity of Gunn
High School has been eliminated with installation of new bike lanes. The GO FAST trip
reduction program at Gunn High School has encouraged students to use alternative modes
of transportation to and from school. Traffic signal improvements are planned for the
Arastradero-Donald intersection to serve the new Terman Middle School. Electronic speed
advisory signs are being deployed on both Charleston and Arastradero to show drivers their
current operating speed and the posted speed limit. Plans are being developed to re-
configure Charleston Road between Mumford and Nelson to enhance pedestrian and bicycle
safety.
Despite these improvements, school commuters on both Charleston and Arastradero Roads
continue to face serious challenges because of existing local and regional traffic. These
challenges will intensify due to future land development and re-development impacting the
Charleston-Arastradero Corridor. Some of the impacts will likely derive from the Hyatt
Rickey’s project at E1 Camino Real and Charleston, the prospective re-development of the
Sun Microsystems site along Charleston between Fabian and San Antonio Road and future
re-development of the Elk Club Site on E1 Camino Real near Hyatt Rickey’s. Individually
and cumulatively, these land use changes will produce additional traffic volume and an
increased number of vehicle turning movements a!ong the Charleston-Arastradero corridor.
The additional vehicular traffic and turning movements onto each street will increase the
amount of conflict with and exposure to vehicular traffic for students cycling and walking
along or across these streets and cross streets. This will make safe, multimodal
transportation, as envisioned in the Palo Alto Comprehensive Plan, more difficult to attain
and preserve for these two important streets and for intersecting streets as well.
DISCUSSION
Staff proposes to develop and implement a Charleston-Arastradero Road Corridor Traffic
Management and Safety Plan to enhance school commute traffic safety, alternative modes
of travel, and residential quality of life, in response to current travel conditions as well as to
the cumulative transportation impacts of anticipated development within the corridor. It will
address the length of Charleston and Arastradero Roads from Fabian to Miranda. The
Traffic Plan will focus on transportation and urban design issues and, thus, will not be a land
use plan. Rather, it will implement existing Comprehensive Plan goals and policies.
One of the primary objectives of the plan is to provide meaningful mitigation for the traffic
impacts from new and existing development. The plan will focus on outcomes such as safe
and attractive routes to schools, well-landscaped medians where possible, and pedestrian,
bicycle, and bus transit improvements along the corridor.
Other primary objectives of the plan will be to provide safer traffic flow along the corridor
and reduce the incidence of vehicle speeding, without reduction in vehicle travel times or
CMR:237:03 Page 2 of 5
causing diversion of through traffic to other streets. The plan is not intended to delay
possible short-term improvements while longer-term solutions are explored. Short-term
improvements will proceed as identified and scheduled.
The requirements of all departments within the City and other agencies (including Caltrans)
will be acknowledged and addressed. The plan will be a shared and comprehensive effort
managed by the Transportation Division in collaboration with other City departments. Other
agencies and entities, including Caltrans, the Peninsula Corridor Joint Powers
Board!Caltrain, Palo Alto Unified School District, and the Santa Clara Valley Water District
will also be involved in plan development. Attachment B contains the proposed scope of
work.
The Traffic Plan is anticipated to be completed within six to nine months of initiation.
Completion of the Traffic Plan is necessary before permitting additional traffic-generating
development projects in this Corridor. The proposed ordinance would disallow
consideration of any new land development or re-development that: 1) is located within 440
yards of the Charleston Corridor; and 2) would result in the addition of one or more
residential dwelling units or more than 250 non-residential square feet to the conditions
existing on April 14, 2003. Individually developed single family dwellings and duplexes
are to be exempted from these provisions. The Director of Planning and Community
Environment and his staff will prepare implementation guidelines for this ordinance, subject
to approval as to form by the City Attorney. The ordinance requires a Council finding that it
is necessary for the preservation of the public health, safety, and welfare to implement the
Charleston Road Corridor Traffic Management and Safety Plan before permitting additional
traffic-generating development projects in the Charleston Road Corridor. The ordinance
would be effective immediately upon its adoption and would conclude on the earlier of the
expiration of the 18th month following the effective date, or the completion of
implementation of the Charleston Road Corridor Traffic Management and Safety Plan, as
determined by the Director of Planning and Community Environment.
The ordinance calls for expedited development of a Charleston-Arastradero Road Corridor
Traffic Plan including, but not limited to, allowing the City Manager to enter into
professional service or consulting contracts without formal or informal bidding, as
authorized by the Municipal Code. In addition, Council is asked in the ordinance to state
that it determines that it can be seen with certainty that there is no possibility that this
ordinance may have a significant effect on the environment. The ordinance is exempt from
the provisions of CEQA as a regulatory measure taken to assure the maintenance,
restoration, enhancement, or protection of the environment.
CMR:237:03 Page 3 of 5
RESOURCE IMPACT
The Plan will require a City expenditure of $200,000, to be reimbursed by development
contributions in the form of mitigation funding from prospective development and re-
development along the Charleston-Arastradero Road corridor.
POLICY IMPLICATIONS
The Charleston-Arastradero Road Corridor Traffic Management and Safety Plan addresses
the first five Goals of the Palo Alto Comprehensive Plan:
e T-1 : "Less Reliance on Single Occupant Vehicles".
e T-2: "A Convenient, Efficient Public Transportation System that Provides A Viable
Alternative to Driving".
T-3: "Facilities, Services,and Programs that Encourage and Promote Walking and
Bicycling".
T-4: "An Efficient Roadway Network for All Users".
T-5: "A Transportation System that Minimizes Impacts on Residential Neighborhoods".
ENVIRONMENTAL REVIEW
An Environmental Assessment will be prepared and presented to the Planning and
Transportation Commission and City Council for consideration along with the draft
Charleston-Arastradero Road Corridor Traffic Management and Safety Plan. Since the
corridor plan is intended to implement important provisions of the Comprehensive Plan, an
important focus of the Environmental Assessment will be consistency of the corridor plan
with the Palo Alto Comprehensive Plan.

ORDINANCE OF THE COUNCIL OF THE CITY OF PALO
ALTO DECLARING COUNCIL POLICY TO IMPLEMENT THE
CHARLESTON ROAD CORRIDOR TRAFFIC .MANAGEMENT AND
SAFETY STUDY BEFORE PERMITTING ADDITIONAL
TRAFFIC GENE~hTING DEVELOPMENT PROJECTS IN THE
CHARLESTON ROAD CORRIDOR AND DECLARING THE
URGENCY THEREOF
The Council o{ the City of Palo Alto does ORDAIN as
follows:
SECTION !.
declares as follows:
The Council finds and
A.The Charleston Road Corridor comprises Charleston
and ~-- ¯A:=stradero Roads, from Miranda Avenue to Fabian Way
B.The 1998-2010 Palo Alto Comnrehensive Plan
("Comnrehensive Plan") designates this corridor as a residential
arterial because it carries large volumes of through-traffic but
also has residential uses on both sides of <he street.
C.The Comprehensive Plan states that the City’s
objective for residential arteria!s is to address the desires of
residents of these streets who would like to have slower speeds,
safer conditions for bicycles and pedestrians, and aesthetic
imnrovemen<s.
D.The Comprehensive Plan states that this must be
done economically and without appreciably reducing traffic
capacity or diverting traffic onto loca! neighborhood streets.
Examples of improvements are "boulevard" treatments (landscaped
medians and planting strips), gateway features, and traffic
signal changes, in addition, improved alternate transportation
modes are supported.
E.in December 2000, the City received a report
entitled, Charleston Road Corridor Traffic Management and
Study. This City-co~missioned report identified several
findings and recommendations including:
The real and perceived unsafe conditions on
Chariesnon Road that compromise bicyclist safety;
The real and perceived unsafe conditions for
~=d=<nrlans crossing Char!es~on Road; and

030409 sm 005323
F.The Charleston Road Corridor is a unique
transportation corridor in the City of Pa!o Alto because ofthe
concentration of schoo!, recreational and other public assembly
facilities on or immediately adjacent to the corridor. These
facilities include Gunn Senior High School, Terman Park, Terman
Park Library, Jane Lathrop Stanford Middle Schoo!, Fairmeadow
Elementary School, Achieve School, Challenger Schoo!, Juana
Briones Elementary School, Juana Briones Park, Hoover Elementary
Schoo!, Rob!es Park, Mitchel! Park, Mitchel! Park Library,
Mitchel! Park Community Center, Cubber!ey Community Center, Mid-
Peninsula Jewish Community Day Schoo!, and the new Terman Middle
School to be re-opened in the Fal! of 2003. Moreover, while it
is located just outside the current Charles<on Corridor between
San Antonio Road and Fabian Way, the relocated Jewish Community
Center wil! create a major new community center and housing use
when it is deve!oped on the former Sun Microsysrems site. These
facilities serve a large segment of Pa!o A!to’s youth population
and therefore require safe pedestrian and bicycle access.
G.The Charieston Corridor is also unique in that
school commuters must cross several major intersections, such as
the state-controlled E1 Cam!no Real (SR 82), Alma Street,
Midd!efie!d Road, and an at-grade Ca!Train rail crossing.
The Char!es[on Road ~<~ ~<a~{~c Management
and Safe~y Stu~s further recognized that the corridor could be
classified as a "school corridor." "Schoo! corridor" would be a
new, specialized form of residential arteria! with specia!
criteria and policies ro address minimum levels of accommodation
for pedestrians and bicyclists, including bike lanes and bike
lane widths, sidewalks and sidewalk widths, minimum and maximum
distance between safe crossings of the corridor, crosswalk
design, pedestrian median refuges,and signa! timing to
accommodate bicycles and pedestrians.
i.The 200S S[atus Report: Comprehensive Plan
imm!ementation Plan indica:es that the Charleston Corridor
residential arterial measures described in the Comprehensive
Plan have not been compie:ed.
J.The City Council wishes to pursue implementation
of the Comorehensive P!an and Charies~on Road Corridor Traffic
Management and Study before additiona! new development
exacerbates existing unsafe traffic conditions.

K.The City Council hereby finds and determines that
it is necessary for the preservation of the public health,
safety, and welfare to implement the Charleston Road Corridor
Traffic Management and Safety Study before permitting additional
traffic generating deve!opment projects in the Charleston Road
Corridor.
L.The City Council hereby finds and declares that
this Ordinance is necessary as an emergency measure because
pending and reasonably anticipated development applications wil!
cause serious, irreversible degradation to traffic conditions in
the Charleston road Corridor. This degradation wi!] cause
i~mediate threats to the safety of schoo! children and
pedestrian and bicycle commuters. Moreover, existing vehicular
traffic conditions wil! be substantially worsened.
SECTION 2. RESTRICTIONS ON DEVELOPMENT APPLZCATIONS.

Scope Of Work
Task 1
a)
b)
c)
d)
Task
: Existing Conditions and Plan Criteria
Data collection - Compile data on vehicle speeds and volumes, cycling and pedestrian
volumes, intersection level of service, cycling level of service, and crash data for the
corridor. Existing data may need to be supplemented by additional data in order to
complete the required data set.
Road Safe~. Audit - Conduct road safety audit of entire corridor, including conditions
pertaining to safety of pedestrians, bicycles, and motor vehicles. Special emphasis should
be given to the needs of children, the elderly, and the mobility-impaired. Due attention
should be given to school commute travel barriers such as Caltrain tracks and major
intersections.
Data Analysis - Analyze existing and forecast (to the year 2025, the citywide computer
traffic model horizon year) motor vehicle traffic volumes, cycling and pedestrian
volumes, and both motor vehicle and cycling levels of service.
Residential AmeniO" Evaluation - Review urban design and landscape architecture
(including tree canopy, potential for landscaped center medians, and landscape strip
plantings) amenities of the corridor.
Petfo~w~ance Criteria - Prepare set of Corridor Performance Criteria, including target
motor vehicle level of service, pedestrian and cycling levels of service, target 85 percent
motor vehicle speeds, target alternative modes share of travel (school commuter and all
trip purpose) along the corridor, target reduction in corridor crashes, target improvements
in residential, landscape, and urban design anaenity along the corridor, and target
minimum allowable traffic shift to other residential streets along the corridor due to plan
improvements. Performance criteria, based on input from residents and City staff, should
address effectiveness, cost, aesthetics, and level of community support, environmental
impacts, and measurable performance standards for transportation patterns after
implementation.
2: Alternatives Development and Evaluation
a)Develop and evaluate alternatives to maintaining motor vehicle level of service while
improving cycling and pedestrian level of service, as well as residential, urban design,
and landscape amenity such as to meet or exceed performance targets. Alternatives may
include closure of bike lane gaps, creation of bulb outs (curb extensions) to shorten
crosswalk distances, a pedestrian/bicycle undercrossing of Caltrain, creation of median
refuges for pedestrian crossings, enhancement of crosswalk visibility through such
measures as pedestrian-activated pavement lighting, crosswalk pavement and painting
treatments, along with signage improvements. The Pato Alto Citywide Transportation
and Land (Nexus) Study findings, especially the Plan Line Study and multimodal
transportation forecast model upgrade components will inform this work.
b)Develop and evaluate various congestion mitigation alternatives, including improved
traffic signal coordination, traffic signal timing and phasing improvements, cycling,
pedestrian, and transit improvements, new bicycle/pedestrian undercrossing of Caltrain,
and travel demand management efforts such as Gunn High School’s GO FAST program.
The Palo Alto Citywide Transportation and Land (Nexus) Study findings, especially the
Plan Line Study and multimodal transportation forecast model upgrade, will inform this
work.
c)Develop and evaluate various alternatives to traffic calming on the corridor in order to
manage vehicle speeds, improve travel safety, and enhance residential amenity.
Alternatives should include changes to the street cross-section as appropriate, deployment
of additional LED radar read-out electronic speed signs, consideration of innovative
forms of intersection control, traveler education and awareness programs such as Pa!o
Alto’s new Pace Car Program, and improvements in lane markings and delineation, as
well as sig-nage. Emphasis should be given to maintaining vehicle progression at a
slower, but more consistent speed.
d)Develop and evaluate various urban design, landscape architecture, and public art
improvement alternatives to enhance residential amenity and aesthetics, including
landscaped center medians, landscape planting strips, enhancement to tree canopy, and
aesthetic improvements to street furniture and street li~hting.
Task 3: Preliminary Concept Plans
Prepare and evaluate four preliminary concept plans. Prepare educational outreach materials and
conduct Community Forum #1. A creative approach to the allocation of space and treatment of
transportation needs and residential amenity and urban design requirements will be necessary for
success of the concept plans. Due consideration should be given to motor vehicle design speeds,
number of travel lanes, treatment of pedestrian crossings, width and placement of cycling lanes,
and lane widths.
a)The concept plans will be general, diagrammatic plans of measures applied along
segments of the corridor. They will be selected to represent the various right of way
widths and other site conditions present. The concept plans will include design
approaches that can be applied either separately or in combination. These approaches
may address lane width, number and configuration of lanes, median islands, intersection
and traffic signal modifications, ADA access improvements, roundabouts, pedestrian
crossing improvements, a new bicycle/pedestrian undercrossing of Caltrain, street trees,
bulb-outs, special paving treatment, and public art. Preliminary cost estimates shall be
provided for each concept plan and all measures comprising each plan.
b)Evaluate the pros and of the comprehensive package of measures comprising each
concept plan using Performance Criteria developed in Task 1. Attention should be given
to trade offs amongst such attributes as effectiveness, cost, and community acceptance.
Special emphasis should be given to the issue of minimizing traffic shift onto nearby
residential streets.
c)Explore a variety of urban design treatments with different character and aesthetic
qualities, and involve the community in developing a preferred overall urban design
concept for the corridor.
d)Develop presentation and educational outreach materials to .inform the public about
relevant transportation and urban design principals applied in the concept plans.
e) Plan and conduct Community Forum #2 to review the concept plans.
Task 4: Design Alternatives
From the concept plans develop two design alternatives and conduct Community Forum #3 to
present and review both design alternatives.
Task 5: Draft Final Schematic Plan
Based on community and staff input prepare a draft preferred Final Schematic Plan for review of
the Planning and Transportation Commission.
Task 6: Final Schematic Design Plan and Final Report
Based on Planning and Transportation Commission input, draft a final schematic design plan for
City Council review. Based on Council review, modify the Final Schematic Design Plan and
prepare the Final Report.

SUBJECT:
APRIL 9, 2001 CMR:188:01
CHARLESTON ROAD CORRIDOR TRAFFIC MANAGEMENT
AND SAFETY STUDY
This is an informational report and no Council action is required.
BACKGROUND
At the request of the Charleston Meadow Neighborhood Association and the Green Meadow
Neighborhood Association, Transportation Division staff was directed by the City Manager
to initiate a traffic management and safety study of the Charleston Road corridor. The study
began in June 1999 with formation of a Project Advisory Group (PAG), comprising the
following Palo Alto residents:
1.Deborah Ju 7. Myllicent Hamilton
2.Thomas Vician 8. ¯Shirley Eaton
3.Jean Olmsted 9.Shirley Nanevicz
4.Marion Hill 10.Richard Geiger
5.Tom Crystal 11.Roger Kohler
6.Louise Herring
These neighborhood association representatives expressed concern about a number of traff~c
issues on or impacting Charleston Road, including:
[]Speeding.
[]Traffic congestion on Charleston Road at Alma Street, E1 Camino Real, Middlefield
Road and other corridor intersections.
[]Pedestrian safety and the lack of pedestrian crossings.
[]Cycling safety, particularly for children commuting to schools on or near Charleston
Road.
[] Motor vehicle safety.
c~Cut-through traffic from Charleston Road onto adjacent neighborhood streets.
CMR:188:01 Page 1 of 6
Following a consultant selection process, Wilbur Smith & Associates, a national
transportation planning and engineering firm with offices in San Francisco, was selected to
work with City staff and the PAG.
The PAG, City staff, and the consukant worked collaboratively to address these issues and
to develop recommendations to meet the following broad objectives:
Enhance travel safety for all modes, with special emphasis on cyclists and pedestrians
commuting to and from school.
Reduce the impacts of traffic on residential neighborhoods.
Enhance multimodal travel choices for the Charleston Road corridor.
The Charleston Road Traffic Management and Safety Study Report of Findings
(Attachment A), was reviewed and approved by the Planning and Transportation
Commission on October 25,2001.
DISCUSSION
Existing Situation
The Charleston Road Corridor study limits were E1 Camino Real to the west and Fabian
Way to the east. Charleston Road is a four-lane undivided arterial roadway with posted
speeds of 25 mph that serves South Palo Alto. In combination with Arastradero Road,
Charleston Road serves as an east-west connector to three of the region’s major north-south
roadways: Bayshore Freeway (US 101), Foothill Expressway, and 1-280. There is parking
on the north side of the roadway with fulltime bike lanes. On the southside there is a
daytfine only bike lane that converts to a parking lane at night (7 p.m-7 a.m.). The street
cross-section is 60 feet wide. Fronting land uses include single family residential, several
institutional uses (including Hoover Elementary School, the Unitarian Church, the
Community Association for Rehabilitation, and the Stevenson House senior housing
complex). J.L. Stanford Middle School, Hoover Elementary School, and Challenger School
have driveway access onto Charleston Road.
Average daily traffic (ADT) on Charleston Road ranges from approximately 13,500 just
west of Fabian Way to over 14,000 just west of Middlefield and just west of Alma.
Intersection levels of service (LOS) range from B (Charleston Road at Nelson Drive and
Charleston at Wilkie Way) to D in the morning and E in the evening (Charleston at Alma).
(LOS A represents average stopped delay per vehicle of 5 seconds or less and LOS E
represents average stopped delay from 40 to 60 seconds per vehicle. LOS E is the Santa
Clara County Congestion Management Program minimum standard for intersection
operation. LOS D is the Palo Alto Comprehensive Plan LOS threshold.)
CM~:188:01 Page 2 of 6
Charleston Road 85th percentile speeds (the speed at which 85 percent of traffic is traveling
at or below and 15 percent is traveling above) range from 34 mph just west of Fabian Way
to 39 mph just west of Middlefield. The width of Charleston, in combination with relatively
unimpeded vehicle flow on long stretches between intersections, probably induce these 85th
percentile speeds ranging from 9 mph to 14 mph above the posted speed limit.
Peak period bicycle volume counts on the Charleston Road corridor range from 119 from 7
a.m. to 9 a.m. between Nelson Drive and Carlson Circle (in the vicinity of both Hoover
Elementary and JLS Middle School) to 33 just east of Middlefield Road. There is evidence
of a significant amount of wrong-way riding and riding on sidewalks. During the morning
peak period, for example, 80 of the 119 bicycles counted between Nelson Drive and Carlson
Circle were either riding the wrong way on a bike lane or riding on the sidewalk.
The study documented cut-through traffic between Alma Street and Charleston Road via
Lindero Drive and Carlson Circle, via Ely Place and Mumford Place, and at other locations
in neighborhoods flanking Charleston Road east of Alma Street. Anecdotal evidence was
collected on cut-through traffic from Charleston Road to Louis Road.
The study also documents 139 accidents on Charleston Road between and including the
intersections of Fabian Way and E1 Camino Real. Over one-third of these (49) were rear-
end collisions that tend to occur on roadways with relatively high vehicle speeds and
without turn pockets to remove turning vehicles from through lanes. There were 17
documented vehicle collisions with cyclists or pedestrians. It should be noted that these data
include only those accidents resulting in injury, thus exclude collisions involving property
damage only or near misses.
There are long stretches on Charleston Road without a pedestrian crossing, including about
a 1,100-foot gap in crossing opportunity between Wilkie Way and Alma Street. Bicycle
lanes on Charleston terminate on Alma Street. As indicated previously, even in the presence
of bicycle lanes, a large number of cyclists use sidewalks instead. Relatively high vehicle
speeds on Charleston are likely to deter some cyclists from using existing bicycle lanes.
The study recommendations based on thesg findings were as follows:
Traffic Management and Safety Plan: Phase I
A. Policies
Develop criteria to differentiate arterials and collectors that are school commute
corridors from other arterials and collectors, as well as a framework for reducing
motor vehicle traffic impacts on such corridors. These criteria should emphasize
appropriate traffic speeds and volumes (both existing and projected based on regional
CMR:188:01 Page 3 of 6
growth and land development occurring on or near the corridor) for a school
commute corridor.
2.Once school commute criteria are established, consider the suitability of Charleston
Road as a school commute corridor.
o Establish a comprehensive, periodic data collection and evaluation program on
school commute corridors, including information on vehicle speeds and volumes,
accidents, and bicycle and pedestrian volumes. Data should be collected frequently
enough for seasonal variationsin transportation behavior to be documented. The
existing Fairview School Accident Reporting System should be considered for
integration with these data sets. School and PTA involvement in supplementary data
collection should be encouraged.
Increase enforcement of traffic laws on Charleston/Arastradero and East Meadow
corridors. Use of radar enforcement on weekdays when children are present is
enforceable when a street is posted with the school area speed limit of 25 mph, as is
the case for Charleston Road.
B. Projects and Programs
Evaluate the extent and impact of vehicle speeds and cut-through traffic on Louis
Road from vehicles turning into Louis from Charleston Road, and develop
appropriate mitigation measures for these impacts.
o Develop and implement, in conjunction with the Palo Alto School District and the
PTA, a school commute trip reduction program for the Charleston/Arastradero Road
corridor and the East Meadow corridor, which parallels Charleston Road. The City’s
Commute Coordinator would be involved with this effort.
o Develop enhanced adult supervision of children commuting to school along the
Charleston!Arastradero and East Meadow corridors through increased involvement of
parent volunteers as well as City crossing guards. A particularly worthy idea for
school-PTA consideration is the "walking school bus" approach, which teams adults
and children in safe walking groups to and from school.
Devote resources from the City’s new Traffic Safety Education campaign toward the
Charleston!Arastradero and East Meadow corridors.
Traffic Management and Safety Plan - Phase II
Evaluate roadway design alternatives to provide enhanced pedestrian crossing and motor
vehicle safety on Charleston Road between Nelson Drive and Carlson Circle. This work

would be undertaken during Fiscal Year 2001-2002 and would take place in consultation
with affected stakeholders, including residents, neighborhood associations, parent-teacher
associations, schools, cyclists, and commuters. Staff would return to the Planning and
Transportation Commission and Council with results and recommendations from this work.
Implementation of Recommendations
Due to workload and resource constraints, staff has decided to implement only a portion of
the short-term recommendations contained in the Safety Study Report. In response to these
findings and recommendations, staff will be implementing the following with respect to the
Charleston Road Corridor:
1.Develop criteria to differentiate arterials and collectors that are school commute
corridors from other arterials and collectors and to propose a framework for reducing
motor vehicle traffic impacts on such corridors.
2.Once school commute criteria are established, staff will evaluate the suitability of
Charleston Road as a school commute corridor.
3. Establish comprehensive, periodic data collection and evaluation on school commute
corridors, including information on vehicle speeds and volumes, accidents, and bicycle
and pedestrian volumes.
4. Evaluate the extent and hnpact of vehicle speeds and cut-through traffic on Louis Road
from vehicles turning into Louis from Charleston Road and develop appropriate
mitigation measures for these impacts.
5. Develop and implement, in conjunction with the Palo Alto School District and PTA, a
school commute trip reduction plans for the Charleston Road and parallel East Meadow
corridors.
6. Develop and implement, in conjunction with the Palo Ako School District and PTA, a
plan for enhancing - through volunteer effort as well as paid personnel - the supervision
of children commuting to school along the Embarcadero and East Meadow corridors.
7. Conduct traffic safety education outreach efforts focused on Charleston Road drivers,
pedestrians, and cyclists.
8. Evaluate roadway design alternatives to provide enhanced pedestrian crossing and motor
vehicle safety on Charleston Road between Nelson Drive and Carlson Circle.
This work will begin in the first half of fiscal year 2001-2002. Staff wili prepare
recormnendations for review by the Planning and Transportation Commission and Council
in the latter half of fiscal year 2001-2002.
RESOURCE IMPACT
Phase I activities are all achievable with current resources. Phase II work would require
either re-prioritization of Transportation Division activities during fiscal year 2001-2002 or
additional staff resources.

POLICY IMPLICATIONS
The Transportation Element of the 1998-2010 Palo Alto Comprehensive Plan contains
numerous policies related to traffic safety and traffic intrusion, including the following:
Policy T-30: "Reduce the impacts of through-traffic on residential areas by designating
certain streets as residential arterials."
Policy T-39: "To the extent allowed by law, continue to make safety the first priority of
citywide transportation planning. Prioritize pedestrian, bicycle, and automobile safety over
vehicle level-of-service at intersections."
Policy T-40: "Continue to prioritize the safety and comfort of school children in street
modification projects that affect school travel routes."

AND SAFETY STUDY
RECOMMENDATION
Staff recolrmaends that the Planning and Transportation Commission recommend that the
City Council:
1.Adopt, in concept, the Charleston Road Traffic Management and Safety Plan Phase I
and Phase II; and
2.Direct Staff to implement Phase I of the Charleston Road Traffic Management and
Safety Plan.
Should Phase II be approved in concept by Council, staff will prepare requests for
funding a detailed conceptual plan and cost estimates for Charleston Road redesign,
including roundabouts and lane reductions, as well as for neighborhood traffic calming
plans called for in Phase II. These traffic-calming requests will be made as part of the
City’s new Neighborhood Traffic Calming Program. Both the Charleston Road redesign
and neighborhood traffic calming plans would be submitted to the Planning and
Transportation Comnfission for review and to the Council for approval.
BACKGROUND
At the request of the Charleston Meadow Neighborhood Association and the Green
Meadow Neighborhood Association, Transportation Division staff was authorized by the
City Manager to initiate a traffic management and safety study of the Charleston Road
H:\cmrs"~-TC\Charleston Study 1.doc Page 1
corridor. The study began in June 1999 with formation of a Project Advisory Group
(PAG), comprising the following Palo Alto residents:
1.Deborah Ju 7.Myllicent Hamilton
2.Thomas Vician 8.Shirley Eaton
3.Jean Olmsted 9.Shirley Nanevicz
4.Marion Hill 10.Richard Geiger
5.Tom Crystal 11.Roger Kohler
6.Louise Herring
These neighborhood association representatives expressed concern about a number of
traffic issues on or impacting Charleston Road, including:
[]Speeding.
[]Traffic congestion at Alma, E1 Camino Real, Middlefield and
intersections.
ca Pedestrian safety and the paucity of pedestrian crossings.
[]Cycling safety.
ca Motor vehicle safety.
ca Cut-through traffic from Charleston onto adjacent neighborhood streets.
other corridor
Following a consultant selection process, Wilbur Smith & Associates, a national
transportation planning and engineering ftrm with offices in San Francisco, was selected
to work with City staff and the PAG.
The PAG, City staff, and consultant worked collaboratively to address these issues and to
develop recommendations to meet the following broad objectives:
Enhance travel safety for all modes, with special emphasis on cyclists and pedestrians
commuting to and from school.
Reduce the impacts of traffic on residential neighborhoods.
Enhance multimodal travel choices for the Charleston Road corridor.
The work of staff, the PAG, and consultant is now complete. A Draft Report of Findings
and Recommendations is appended as Attachment 1. The PAG-has endorsed the
complete set of recommendations presented in detail in the Draft Report and summarized
in a later section of this staff report.
DISCUSSION
The Charleston Road Corridor study lhnits, as identified on Figure 1, "*’ere E1 Camino
Real to the west and Fabian Way to the east. Charleston Road is a four-lane undivided
arteria! roadway with posted speeds of 25 mph that serves South Palo Alto. In

Expressway, and 1-280. There is parking on the northside of the roadway with fulltime
bike lanes. On the southside there is a daytime only bike lane that converfs to a parking
lane at night (7 p.m-7 a.m.). The street cross-section is 60 feet wide. Fronting land uses
include single family residential, several institutional uses (including Hoover Elementary
School, the Unitarian Church, the Coimnunity Association for Rehabilitation, and
Stevenson House senior housing complex). J.L. Stanford Middle School, Hoover
Elementary School, and Challenger School have driveway access onto Charleston Road.
Average daily traffic (ADT) on Charleston Road ranges from approximately 13,500 just
west of Fabian Way to over 14,000 just west of Middlefield and just west of Ahna.
Intersection levels of service (LOS) range from B (Charleston at Nelson and Charleston
at Wilkie Way) to D in the AM and E in the PM (Charleston at Alma). [It should be noted
that LOS A represents average stopped delay per vehicle of 5 seconds or less and that
LOS E represents average stopped delay from 40 up to 60 seconds per vehicle. LOS E is
the Santa Clara County Congestion Management Program minimum standard for
intersection operation. LOS D is the Palo Alto Comprehensive Plan LOS threshold.]
Charleston Road 85th percentile speeds (the speed at which 85 percent of traffic is
traveling at or below and 15 percent is traveling above) range from 34 mph just west of
Fabian Way to 39 mph just west of Middlefield. The wide cross-section of Charleston, in
combination with relatively unimpeded vehicle flow on long stretches between
intersections, probably induce these 85t~ percentile speeds ranging from 9 mph to 14 mph
above the posted speed limit.
Peak period bicycle volume counts on the Charleston Road corridor range from 119 from
7 a.m. to 9 a.m. between Nelson and Carlson (in the vicinity of both Hoover Elementary
and JLS Middle School) to 33 just east of Middlefield. There is evidence of a significant
amount of wrong-way riding and riding on sidewalks. During the morning peak period,
for example, 80 of the 119 bicycles counted between Nelson and Carlson were either
riding the wrong way on a bike lane or riding on the sidewalk.
The study documented cut-through traffic between Alma and Charleston via Lindero and
Carlson Circle, via Ely Place and Mumford Place, and at other locations in
neighborhoods flanking Charleston Road east of Alma. Anecdotal evidence was collected
on cut-through traffic from Charleston to Louis Road.
The study also docmnents 139 accidents on Charleston Road between and including the
intersections of Fabian Way and E1 Camino Real. Over one-third of these (49) were rear-
end collisions that tend to occur on roadways with relatively high vehicle speeds and
without turn pockets to remove turning vehicles from through lanes. There were 17
docmnented vehicle collisions with cyclists or pedestrians. It should be noted that these
data include only those accidents resuking in injury, thus exclude collisions involving
property damage only or near misses.
H:\cmrskP-TC\Charleston Study 1 .doe Page 3
There are long stretches on Charleston Road without a pedestrian crossing, including
about a 1,100-foot gap in crossing opportunity between Wilkie Way and Alma. Bicycle
lanes on Charleston terminate on Alma. As indicated previously, even in the presence of
bicycle lanes, a large number of cyclists use sidewalks instead. Relatively high vehicle
speeds on Charleston are likely to deter some cyclists fxom using existing bicycle lanes.
Recommendations of the Traffic Management Plan
The Traffic Management and Safety Plan contains recormr~endations to address
problematic trave! conditions on Charleston Road. The recormrtendations fall into
several categories: policies, projects and programs, roadway design and operation, and
residential traffic (ahrdng. The Plan is presented in two phases. The first phase can get
underway immediately. The second phase will require additional time for development
(including design and construction where applicable) and, in some cases, securing funds
for capital investments. Taken together, the two phases comprise a comprehensive
approach to Charleston Road transportation management, including engineering,
enforcement, education, and travel demand management measures.
The following elements comprise Phases I and II of the proposed Charleston Road
Traffic Management and Safety Plan:
Traffic Management and Safety Plan - Phase I
A. Policies-
Develop crkeria to differentiate arterials and collectors that are school cormnute
corridors from other arterials and collectors, as well as a framework for reducing
motor vehicle traffic impacts on such corridors. These criteria should emphasize
appropriate traffic speeds and volmnes (both existing and projected based on regional
growth and land development occurring on or near the corridor) for a school cormnute
corridor.
o Once school cormnute criteria are established, consider the suitability of Charleston
Road as a School Conmmte Corridor.
Establish a comprehensive, periodic data collection and evaluation program on School
Co~r~nute corridors, including information on vehicle speeds and volmnes, accidents,
and bicycle and pedestrian volumes. This should be undertaken in conjunction with
development of an Annual Report on Transportation Conditions and Trends in Palo
Ako, which Council has already mandated be developed by the Transportation
Division. Data should be collected frequently enough for seasonal variations in
transportation behavior to be documented. The existing Fairview School Accident
H:\,cmrs’,t~.TC’~Charleston Stud), 1 .doc Page 4
Reporting System should be considered for integration with these data sets. School
and PTA involvement in supplementary data collection should be encouraged.
Encourage use of Page Mill and San Antonio/El Monte Road between Foothill
Expressway and 1-280, rather than Arastradero Road, through use of directional
siguage. [In Phase II, more active measures are proposed.]
Increase enforcement of traffic taws on Charleston/A_rastradero and East Meadow
corridors. Use of radar enforcement on weekdays when children are present is
enforceable when a street is posted with the school area speed limit of 25 mph, as is
the case for Charleston Road.
B. Projects and Programs-
Evaluate the extent and .impact of vehicle speeds and cut-t~ough traffic on Louis
Road from vehicles turning into Louis from Charleston Road, and develop appropriate
mitigation measures for these impacts.
o Develop and implement, in conjunction with the Palo Alto School District and the
PTA, a school commute trip reduction program for the Charleston/Arastradero Road
corridor and the East Meadow corridor, which parallels Charleston Road. The City’s
Commute Coordinator will be involved with this effort.
Develop enhanced adult supervision of children commuting to school along the
Charleston!Arastradero and East Meadow corridors through increased involvement of
parent volunteers as well as City crossing guards. A particularly worthy idea for
school-PTA consideration is the "walking school bus" approach, which teams adults
and children in safe walking groups to and from school.
Devote resources from the City’s new Traffic Safety Education campaign toward the
Charleston/Arastradero and East Meadow corridors.
Traffic Management and Safety Plan - Phase II
A. Roadway Design and Operations -
Restripe Charleston Road to have one through lane in each direction between, but not
including, Middlefield and E1 Camino Real and between, but not including,
Middlefield and Fabian Way. Provide left rams at the following intersections: Alma,
Wilkie Way, Carlson Road, Nelson Road, Louis Road and Fabian Way. A level of
service analysis showed that this would have no negative impacts on vehicular level
of service at these six intersections (existing and future LOS are depicted in Table 1
H:\cmrs\P-TC’\Charleston Study 1.doc Page 5
of Attachment 1). Charleston Road at E1 Camino Real and at Middlefield Road
would need to retain two approach lanes in order to maintain acceptable levels of
service. This redesign would also have a traffic calming effect by changing the look
of Charleston Road from a wide arterial!expressway feel to more of a neighborhood
collector street in anticipation of it being designated a school corridor.
Benefits of Recommendation II.A. 1:
~. No adverse effect on vehicular level of service;
~.Improved pedestrian safety due to center median (raised or striped) facilitating
pedestrian crossings between signalized intersections;
~. Provides bike lane in between the through lane and right turn lane at Ahna Street;
~Provides exclusive left-turn lanes at Wilkie, Carlson, and Nelson; Left-turn phasing
can either be protected or permitted. 1
Advantages of protected left-turn phasing: the pedestrian phase is a separate pha~ from the left turn phase, reducing or
eliminating the possibility of let,-turning vehicles seeing a gap in opposing traftic and ~eeding up to make it through the gap,
only to f’md a pedestrian in the crosswalk. Disadvantages of protected left-turn phasing are that the overall phase length is
longer, causing more delay for the pedestrians waiting tbr the pedestrian W,%LK phase.

Wilbur Smith Associates, February 15, 2000
If Recommendation II.A. 1 were implemented, the following improvements would also be
possible to improve pedestrian and bicycle safety and slow traffic down to the posted
speed limit:
Provide a raised median refuge at locations where pedestrian crossings are to be
chatmeled such as west of Park Boulevard and at Sutherland Drive.
Provide a raised median at signalized intersections at Nelson Drive and Carlson
Circle.
4.Bulb-outs for pedestrians could be added at spot locations.
5.Separate right-turning traffic from bike lanes at Alma Street by providing a separate
right-turn lane and placing the bike lane to the left of the right-turn lane.
H:\crncs"~-TC\Charteston Study 1 .doc Page 7
Other measures affecting roadway operations include:
o
o
Re-evaluate striping at Fabian/Charleston to encourage use of Fabian Way to access
San Antonio. Increase signage to direct cars to Fabian Way.
Conside) planting trees to improve the aesthetics of the street and slow traffic.
These could be either in a median or in a widened planter strip.
Evaluate the possibility of replacing signals at Wilkie, Carlson, and Nelson with
roundabouts. If replaced, consider pedestrian signals if necessary, to provide an
adequate gap in the traffic for pedestrians to safely and conveniently cross
Charleston Road.
10.
Restripe or otherwise rectify the problem caused by the mis-alignment of Park Blvd.
at Charleston Road so that the northbound cars turning from Park Boulevard onto
Charleston Road are not b!ocked by the queue of cars at Alma. Northbound cars
currently b!ock the bike lane to budge into the stopped queue of traffic.
Provide eight-foot wide bike lanes, which may reduce the incidents of sidewalk bike
riding by children.
11. Provide bike lanes on Charleston Road east of Middlefield Road.
12.Convert part-time bike lane to be a fulltime bike lane on the northside of Charleston
Road between Wright Place and the bike path to JLS Middle School. The bike lane
is currently daytime only (7 a.m. to 7 p.m. bike lane). There would be no impacts to
adjacent property owners since no homes front onto this side of Charleston Road.
13.Evaluate the effectiveness of the 4-way stop at East Charleston Road at
Grove/Sutherland.
B. Residential Traffic Calming -
Issues:
Cut-through traffic on Lindero!Wright/Carlson Circle and Greemneadow/Nelson to
avoid congestion at Charleston Road and Alma.
Speeding and cut-thxough traffic on other local streets, to avoid the eastbound backup
at Alma. For example, Wilkie Way is used to access Whitclem Drive and Edlee
Avenue. These two streets are wide and straight with rolled curbs and parallel
parking. The parking is sparse, yielding a wide-open vista xvhich makes it very
conducive to speeding.
1. Develop a traffic cahning plan for Lindero/Wright/Carlson Circle.
2. Develop a traffic calming plan for Ely!Muntford Place.
H:’\cmrs~P-TC\Charleston Study 1 .doc Page 8
3. Develop a traffic calming plan for Green Meadow Way and Nelson Drive.
4. Develop a traffic calming plan for Louis Road.
There are several traffic calming strategies that could help alleviate the problems of
speeding and cut-through traffic. The specific strategies used should be chosen in
conjunction with affected neighbors. The most promising traffic Caiming strategies are:
~Stripe shoulder or parking lane to narrow roadway;
,Retain lack of center line;
¯Install traffic circles at all intersections an&Zor speed humps or tables midblock;
~Consider one-lane choke points or rumble strips;
,If speeding is still a problem, install a peak hour barrier on a timer, that would
close the street midb!ock only during a few hours a day, for example 7:00 a.m. to
8:30 a.m. and 4:30 p.m. to 6:00 p.m.
Phasing and Implementation
The recommended projects vary in the timeframe in which they can be implemented and
also in the entities that need to be involved. Table 2 presents the primary entity or
entities that would need to be responsible for implementation of each of the
recommendations, including the Planning Division, the Transportation Division, the City
Council, the school district and the Police Department. The recommendations have also
been assigned to three phases. Projects in Phase I can be implemented with existing
resources within the next 12 months. Projects in Phase II require City Council action for
additional budget allocation and could be hnplemented within one to three years. Projects
in Phase III would also require City Council action for additional funds (capital
hnprovement program, grants, interagency agreements, cost sharing) and would probably
take several more years to implement.
Existing city and state programs also dovetail with the recormnendations of this report.
These are described below:
The City of Palo Alto has begun a citywide Neighborhood Traffic Calming Program.
The City is also currently working on the Downtown North Traffic Calming Study.
Funding is available for $100,000 worth of traffic calming improvements for local and
collector streets.
The City has also begun a Residential Arterial Traffic Calming Program, the ftrst phase
of which was an Embarcadero Road study. It may be possible to fur~er develop the
H:\cmrs~-TC’,Charleston Study 1.doc Page 9
long-term solutions under the next phase of this study, if Charleston Road is studied
under this program.
The State of California has developed a grant program for Safe Routes to School, and al!
of the improvements in this docmnent have benefits for school commuting, especially the
recommendations for Charleston Road.

study for the Charleston/Arastradero corridor. No funding or timetable, however, has
been established for this study.
H:\cmrs~,P-TC\Charleston Study 1.doc Page 10
2.Authorize and implement Phase I recommendations, evaluate results, then remm to
both the Planning and Transportation Commission and Council with staff
recommendations for further action, if any.
o Recommend that City Council authorize and staff implement both phases of the
Traffic Management and Safety Plan without a second round of Commission and
Council hearings on a detailed Conceptual Plan for the re-configuration of Charleston
Road. It is important to note that staff does not yet have a sufficiently detailed
program for the re-configuration from which to present reliable cost estimates to
Council. Additional detail on location, size, and other aspects of proposed
improvements will also create a better information base for the public, Commissionl
and Council to evaluate the benefits and impacts of the re-configuration.
POLICY IMPLICATIONS
The Transportation Element of the 1998-2010 Palo Alto Comprehensive Plan contains
numerous goals, policies, and progrmns related to traffic safety, traffic calming, trip
reduction programs, and encouragement of bicycling and walking as travel modes.
Goal T-l: "Less Reliance on Single-Occupant Vehicles"
Policy T-3: "Support the development and expansion of comprehensive, effective
programs to reduce auto use at both the local and regional levels."
Program T-8: "Create a long-term education program to change the travel habits of
residents, visitors and workers by informing them about transportation alternatives,
incentives and impacts. Work with the Palo Alto Unified School District and with
private interests, such as the Chamber of Commerce, to develop and implement this
program."
Goal T-3: "Facilities, Services, and Programs that Encourage and Promote
Walking and Bicycling"
Policy T-14: "Improve pedestrian and bicycle access to and between local destinations,
including public facilities, schools, parks, open space, employment districts, shopping
centers, and multi-moda! transit stations."
Policy T-40: "Continue to prioritize the safety and comfort of school children in street
modification projects that affect school travel routes."
Goal T-5: A Transportation System with Minimal Impacts on Residential
Neighborhoods."
H:\cmrs’,iP-TC\,Charleston Study !.doc Page 11
Policy T-30: "Reduce the impacts of through-traffic on residential areas by
designating certain streets as residential arterials."
Policy T-34: "Implement traffic calming measures to slow traffic on local and collector
residential streets and prioritize these measures over congestion management. Include
traffic circles and other traffic cahning devices among these measures."
Program T-4.1: "The foll0wing roadways are designated as residential arterials. Treat
these streets with landscaping, medians, and other visual ianprovements to distinguish
them as residential streets, in order to reduce traffic speeds Charleston/Arastradero
(between Miranda and Fabian Way)."
Goal T-6: "A High Level of Safety for Motorists, Pedestrians and Bicyclists on Palo
Alto Streets."
Policy T-39: "To the extent allowed by law, continue to make safety the ftrst priority
of citywide transportation planning. Prioritize pedestrian, bicycle, and automobile
safety over vehicle level-of-service at intersections."
Program T-47: ’1ftilize engineering, enforcement, and educational tools to hnprove
traffic safety on City roadways."
