1.0 INTRODUCTION
1-1 January 13, 2009
1.0 INTRODUCTION
Two separate projects are being proposed simultaneously in the vicinity of Stanford University,
east of the City of Palo Alto. One would redevelop a portion of the Stanford University Medical
Center facilities and the other would expand Stanford Shopping Center. The operator of
Stanford Shopping Center (Simon Property Group) has applied to the City of Palo Alto for the
addition of 240,000 square feet of new retail stores and restaurants, a new 120-room hotel and
1,199 net new vehicular parking spaces. Stanford University Medical Center (SUMC) has also
submitted an application to add a net of 1,311,469 square feet of hospital and medical office /
clinic facilities that includes the rezoning of land from ‘Public Facilities’ to a new hospital zone.
Buildings will be demolished and rebuilt in phases to meet the latest codes and standards.
The scope of work for the Traffic Impact Analysis will identify and evaluate existing and potential
future traffic conditions associated with the proposed projects. The potential impacts are
evaluated relative to the operation of public transportation, bicycle and pedestrian
transportation, arterial roadways, intersections, freeways, and transportation demand
management (TDM) strategies.
1.1 Applicable Plans and Policies
The study area, shown in Figure 1-1, is part of the City of Palo Alto and the adjacent cities of
Menlo Park and East Palo Alto. Transportation planning in Palo Alto and the surrounding area
is subject to the regulations of Federal, State, regional, and local agencies and programs.
Federal regulations are administered by the Federal Highway Administration (FHWA) and the
Federal Transit Administration (FTA). The California Department of Transportation (Caltrans) is
responsible for State roadways, and regional issues are addressed by the Metropolitan
Transportation Commission (MTC). Congestion Management Agencies (CMAs) of both Santa
Clara County and San Mateo County have developed regulations and policies with relevance to
the proposed projects at the local level.
1.2 Federal Agencies
MTC, which is a regional San Francisco Bay Area agency, implements polices by the FHWA
and the FTA. It oversees transportation improvements in the nine-county Bay Area. It is also
tasked with the development of the local State Transportation Improvement Program (STIP). In
addition, the Transportation Equity Act for the 21st Century (TEA-21) empowers the MTC to
determine the mix of transportation projects best suited for the region’s needs.
1.3 State Agencies
Caltrans is the State agency responsible for State transportation facilities. It has jurisdiction
over State highways in the study area, including El Camino Real (State Route 82), Bayshore
Freeway (U.S. 101), Interstate 280, and the Dumbarton Bridge (State Route 84). Plans to
provide new access or alterations to existing access to a State Route require Caltrans approval.

1.0 INTRODUCTION
1-3 January 13, 2009
Roadway improvements within a State right-of-way also need Caltrans approval, and the
approval process usually includes the development of detailed roadway geometrics and design
plans.
1.4 Regional Agencies
MTC is the metropolitan planning agency in charge of transportation planning, coordinating and
financing for the nine-county San Francisco Bay Area. MTC distributes Federal and State funds
to local projects and programs. MTC and the Association of Bay Area Governments (ABAG)
jointly develop land use projections that are critical inputs for travel demand projections used in
transportation analysis. The Peninsula Corridor Joint Powers Board (JPB) is the tri-county
agency (San Francisco, San Mateo, and Santa Clara counties) that has jurisdiction over the
Caltrain rail service. The Dumbarton Bridge Bus Service (Line DB) is operated by AC Transit
and funded by a consortium of several county transit districts, including the Santa Clara Valley
Transportation Authority (VTA), SamTrans and the Bay Area Rapid Transit District (BART).
The Bay Area Air Quality Management District (BAAQMD) provides both policy guidance and
regulatory control over stationary and mobile air pollution sources. Under the California Clean
Air Act (CCAA) of 1988, the BAAQMD is required to prepare a Clean Air Plan (CAP) to achieve
State standards for ozone and CO. The 2007 Ozone Strategy, jointly prepared by the MTC and
ABAG, will show how the San Francisco Bay Area plans to comply with the State air quality
standards for ozone and how the region will reduce transport of ozone and ozone precursors to
neighboring air basins. Control measures will be established and adopted in the 2007-2009
timeframe.
The CCAA states that strategies should emphasize reducing emission from transportation and
other area-wide sources. The Act requires air districts to adopt, implement and enforce
Transportation Control Measures (TCMs). The MTC develops, maintains and updates a list of
TCMs and distributes this information to keep the BAAQMD informed of trends.
1.5 Local Agencies
The Congestion Management Agencies (CMA) of both Santa Clara County and San Mateo
County have regulations and policies that are relevant to the proposed project.
1.5.1 Santa Clara County
The Santa Clara Valley Transportation Authority (VTA) is the CMA for Santa Clara
County. It oversees the Congestion Management Program (CMP) that defines
methodologies and procedures for determining the transportation impact of a potential
project. The most recent guidelines were updated in 2004. The following are CMP
facilities within the study area by functional classification.

VTA has jurisdiction over public transit in the County. VTA bus service includes several
local and intercity routes in Palo Alto, and the VTA is a member of the Caltrain JPB.
The Santa Clara County Department of Roads and Airports is responsible for County
roadways and airports, including the Palo Alto Airport, Page Mill Roadway, Foothill
Expressway, Oregon Expressway, Stanford Avenue, and Junipero Serra Boulevard.
1.5.2 San Mateo City/County Association of Governments

1.8 Traffic Impact Significance Criteria
Adverse impacts are defined by criteria listed below for Cities of Palo Alto and Menlo Park.
Project impact will be determined using both sets of criteria. Within the main body of this
transportation study, intersections are analyzed according to the City of Palo Alto’s criteria
regardless of the intersection’s location. Roadway segments in Menlo Park are analyzed
according to Menlo Park’s criteria. In Appendix A of this report, the Menlo Park intersections
are also analyzed according to Menlo Park’s criteria for informational purposes since the criteria
are different from those of City of Palo Alto.
1.8.1 City of Palo Alto
Traffic impact would be considered significant when the project results in the following:
x Cause a local (City of Palo Alto) intersection to deteriorate below Level of
Service (LOS) D; or
x Cause a local intersection already operating at LOS E or F to deteriorate in
the average control delay for the critical movements by four seconds or more,
and the critical volume/capacity ratio (V/C) value to increase by 0.01 or more;
or
x Cause a regional intersection to deteriorate from LOS E or better to LOS F; or
x Cause a regional intersection already operating at LOS F to deteriorate in the
average control delay for the critical movements to increase by four seconds
or more, and the critical v/c to increase by 0.01 or more; or

not limited to, spillback queues at project access locations, queues at turn
lanes at intersections that block through traffic, queues at lane drops, queues
at one intersection that extend back to impact other intersections and
spillback queues on ramps; or
x Cause a freeway segment (for each direction of traffic) to operate at LOS F or
contribute traffic in excess of 1 percent of segment capacity to a freeway
segment already operating at LOS F; or

facilities; or
x Impede the operation of a transit system as a result of congestion; or
x Result in inadequate on-site parking supply; or
x Create an operational safety hazard; or
x Result in inadequate emergency access; or
x Cause any change in traffic that would increase the Traffic Infusion on
Residential Environment (TIRE) index by 0.1 or more on a local or collector
residential street.

2.0 EXISTING CONDITIONS
This section of the report presents the existing conditions for the different aspects of
transportation issues within the study area. It covers intersections and roadway analysis as well
as public transit, bicycle and pedestrian facilities and transportation demand management
programs relevant to the proposed projects.
2.1 Intersection and Roadway Analysis
A total of 60 signalized intersections and 3 unsignalized intersections were identified for analysis
in this study. Existing turning movement volumes during peak hours were obtained and
analyzed using TRAFFIX 7.9. 24-hour counts for eight roadway segments were conducted for
seven days to determine their ADT. In addition, volumes for six freeway segments were
obtained.
2.1.1 Intersection Analysis Methodology
The current procedures adopted for intersection operational analysis in Santa Clara
County are according to the Highway Capacity Manual (HCM) 2000. HCM 2000 is
applied via the TRAFFIX 7.9 software package per the requirements of the CMA. Level
of service for signalized intersections is defined in terms of control delay. The definitions
of level of service A through F are noted in Table 2-1. Control delay includes initial
deceleration delay, queue move-up time, stopped delay and final acceleration delay.
Average control delay weights the delay per movement according to the traffic volumes
for that movement. The critical volume to capacity (v/c) ratio is an approximate indicator
of the overall sufficiency of an intersection. The critical v/c ratio depends on the
conflicting critical lane flow rates and the signal phasing. V/C ranges from 1.0 when the
flow rate equals capacity to 0.0 when the flow rate is zero. Values above 1.0 indicate an
excess of demand over capacity. Average critical delay weights the delay for the critical
(conflicting) movements based on the traffic volume for that movement.
There is no specific methodology for analyzing unsignalized intersections in the CMP.
For this report, the HCM 2000 methodology for unsignalized intersection, supported by
TRAFFIX software, is used for unsignalized intersection LOS calculations. Table 2-2
lists the thresholds for the LOS for unsignalized intersections.
LOS rating is based on the weighted average control delay expressed in seconds per
vehicle for all approaches. At two-way or side-street controlled intersections, LOS is
calculated for each controlled movement, not for the intersection as a whole. For single
approaches, the control delay is computed as the average of all movements in that lane.
The threshold values for unsignalized intersections are different than the threshold
values for signalized intersections due to different driver expectations of level of
performance. Higher delay for the same LOS is acceptable at a signalized intersection
as a signalized intersection is expected to serve larger traffic volumes.

The adopted measure for freeway LOS evaluation in Santa Clara County is density,
expressed as passenger cars per mile per lane (pcpmpl). The analysis procedures are
outlined in HCM 2000 but LOS D/E and E/F density thresholds are modified to reflect
Santa Clara County conditions. The LOS thresholds for freeway segments are
presented in Table 2-3.

2.1.2 TRAFFIX
TRAFFIX is a software program that simulates the HCM 2000 analysis methodology.
TRAFFIX evaluates intersection operations based on both average vehicle delay and
critical movement delay. The Santa Clara County CMA and the City of Palo Alto require
the use of TRAFFIX and the evaluation of operations using critical movement delay. In
addition to calculating expected vehicle delay on which level of service is based,
TRAFFIX also calculates the optimal signal cycle length and intersection queuing. The
current version used in this study is Version 7.9.
2.1.3 Analysis Results

* The intersection geometry has recently changed. The traffic operations at this intersection will be updated in the next version of
this report.
The existing geometry of these intersections, as well as the traffic volumes, are shown in
Figure 2-1a through Figure 2-1d and Figure 2-2a through Figure 2-2d, respectively.
Based on the CMP requirements, all intersections operate within satisfactory levels of
service (LOS D or better) during the AM peak hours except for the intersections of El
Camino Real/Page Mill Rd-Oregon Expressway (#16), Junipero Serra Boulevard-Foothill
Expressway/Page Mill Rd (#23), Sand Hill Circle / I-280 (#28), Alpine Road / I-280 NB
Off-Ramp (#62) and Alpine Road / I-280 SB Off-Ramp (#63). El Camino Real / Page
Mill Road-Oregon Expressway (#16) operates at LOS E while the other four
intersections operate at LOS F.

2-13 January 13, 2009
During the PM peak period, El Camino Real / Page Mill Road-Oregon Expressway (#16)
and Bay Road/University Avenue (#54) operate at LOS E while Junipero Serra
Boulevard-Foothill Expressway/Page Mill Road (#23), Galvez / Arboretum Road (#37),
Willow Road / Bayfront Expressway (#52) and Alpine Road / I-280 NB Off-Ramp (#62)
operate below the CMP threshold at LOS F. All other intersections are within acceptable
levels of service for the PM peak hour.
The ADT (total of both directions) for residential roads identified in the study is shown in
Table 2-5. Table 2-5 also notes the existing TIRE index. The TIRE index is a numerical
representation of a resident’s perception of the influence of traffic on daily life. Streets
with TIRE levels above 3.0 are considered traffic-dominated, while those with indexes
below 3.0 are better suited for residential activities. Santa Cruz Avenue, Sharon Road,
Hawthorne Avenue, Everett Avenue and Hamilton Avenue all have indexes above 3.0.

2.2 Transit Services
Figure 2-3 shows the public transit network within the study area. This area is currently served
by buses operated by VTA and SamTrans. In addition, there are free shuttles operated by
Stanford (the Marguerite) that bring students and employees to / from the transit centers (Palo
Alto Transit Center and San Antonio Transit Center in City of Mountain View). The City of Palo
Alto also offers free shuttle service within the City throughout the day. The AC Transit operated
Dumbarton Express connects this peninsula area to the East Bay via the Dumbarton Bridge.
Menlo Park Midday Shuttle ferries passengers between downtown Menlo Park, the Stanford
Shopping Center and Stanford hospital on weekdays. This service is funded by the City of
Menlo Park and the BAAQMD Transportation Fund for Clean Air. Rail service in the study area
consists of Caltrain operating between San Francisco and San Jose.
2.2.1 Bus Service
The Palo Alto Transit Center is a point of convergence for several bus lines operated by
Santa Clara VTA, SamTrans, Stanford University Marguerite Shuttle and the Dumbarton
Express. The Dumbarton Express is a joint BART/VTA/SamTrans/AC Transit/Union City
Transit line between Palo Alto and the Union City BART Station. Other concentrations
of bus lines exist at the Stanford Shopping Center, which is located one-quarter mile
northwest of the Palo Alto Transit Center, and at the intersections of Page Mill Road and
El Camino Real. Details of the different bus routes are presented in Table 2-7.
The table lists routes passing through the study area as well as routes that
originate/terminate in the study area.
SamTrans currently serves the Palo Alto Transit Center with local lines 280, 281,
express route KX, BART/Caltrain connector route 297 and 390. Connections to Stanford
Shopping Center are provided by local lines 280, 281, and express RX/PX. Three
SamTrans bus layover locations are adjacent to the Stanford Shopping Center.
Santa Clara VTA serves the Palo Alto Transit Center with local routes 22, and 35 and
the limited-stop route Bus Rapid Transit (BRT) service 522. Route 35 also serves
Stanford Shopping Center. Route 89 provides service between the Palo Alto Veteran’s
Hospital and California Avenue Caltrain station along Hanover Street in the southeastern
corner of the study area.
AC Transit operates the Dumbarton Express, which provides service between the Union
City BART station and Palo Alto utilizing the Dumbarton Bridge. It also serves the
California Avenue Caltrain Station, North Santa Clara County Offices, Santa Clara
County Municipal Court and the Stanford Industrial Park.
Stanford University Marguerite Shuttle provides free service to the public accessing
many locations on the university main campus such as the Medical Center, Stanford
Shopping Center, Stanford Linear Accelerator, Palo Alto Transit Center, California
Avenue Caltrain Station and downtown Palo Alto. All of the shuttle lines, except for the
Downtown Express are wheelchair accessible. The shuttle operates weekdays from
6:00 am to 8:00 pm, except during university holidays. Marguerite's A and B lines meet

as well as areas within the central campus such as Tresidder, Terman and the Law
School. Line B runs to and from the Palo Alto Transit Center by way of Town & Country
Village thereby serving shoppers throughout the day. Line C serves the California
Avenue Caltrain Station, the main campus, Medical Center and the Stanford West
Apartments. The SLAC shuttle operates Monday through Friday year round (except
campus holidays) between SLAC and Hoover Tower by way of the Oak Creek
Apartments located on Sand Hill Road, West Campus Residences, and the Science &
Engineering Quad, from 7:30 am - 9:00 pm., every 20 minutes. There is also the SLAC
Employee Shuttle that operates weekday mornings 6:27 am - 8:15 am and weekday
evenings 3:10 pm - 5:05 pm, year round (except campus holidays). Stops include
Stanford West Apartments, Palo Alto Transit Center, SLAC Fire Station, Computer
Building, SSRL Gate 17 and the Rosewood Hotel location near I-280. The Midnight
Express is an evening and weekend service that operates from September through
June, linking the campus to the Palo Alto Caltrain station. Shuttle frequency is 15 to 30
minutes.
City of Palo Alto Shuttle is a program with two routes: the Crosstown Shuttle and the
Embarcadero Shuttle. On weekdays, both routes serve the downtown Caltrain station
and transit center. The Palo Alto Shuttle is free and open to everyone. Bus stops are
marked with a "Palo Alto Shuttle" sign, a sticker on a regular VTA bus stop sign, or a
shuttle decal on a stop sign pole.The Crosstown Shuttle runs every half-hour from 7:00
am to 6:00 pm. It connects residential neighborhoods, senior residences and services,
libraries, recreation centers and commercial districts.The Embarcadero Shuttle runs
during the morning, noon and evening commute hours at 15-minute interval. It is
coordinated with the Caltrain schedule, serving employers in the East Bayshore area,
residents in the Embarcadero Road corridor and students at Palo Alto High School.
The Midday Shuttle Service operated by City of Menlo Park is a free community service
route open to the general public. It is especially popular with the seniors. Its key stops
include Menlo Park Library, Belle Haven Library, Menlo Park Senior Center, downtown
Menlo Park, Menlo Park Caltrain station, Menlo Medical Clinic, Stanford Shopping
Center and Stanford Medical Center. The shuttle operates hourly on weekdays between
9.30 am to 3.30 pm. This service is being funded by the city and the BAAQMD
Transportation Fund for Clean Air.
2.2.2 Commuter Rail Service
The Peninsula Corridor Joint Powers Board rail service, Caltrain, runs north-south along
the Peninsula from San Francisco to San Jose with some service extending to Gilroy.
Caltrain is managed by SamTrans, and operates under the jurisdiction of the JPB.
Within the study area, Caltrain stations are at the Palo Alto Transit Center (east of El
Camino Real at University Avenue) and at the California Avenue Station. The current
weekday schedule consists of frequent train intervals (5 to 30 minutes) during commute

hours, with hourly service provided during non-commute times. The earliest northbound
train leaves Palo Alto at 5:01am. The last northbound train departs Palo Alto at 11:04
pm. The first southbound train is at 5:51am while the last southbound train departs Palo
Alto at 12:57am. On weekends, the earliest hourly northbound train leaves Palo Alto at
7:31am (Saturday), the last northbound train departs Palo Alto at 11:01pm (Saturday).
The first southbound leaves Palo Alto 9:02am and the last southbound train departs Palo
Alto at 1:03am (Saturday). Caltrain provides Baby Bullet Express Service that allows
under 1-hour travel between San Jose and San Francisco. This service runs during both
the AM and PM peak hours in both directions, a total of 22 trips each day. In addition,
Caltrain runs Limited-stop Service that serves fewer stations than local service
throughout the day between San Jose and San Francisco.
2.3 Bicycles and Pedestrians
Bicycle travel is an important component of the transportation system connecting Menlo Park,
Palo Alto, Stanford University and Mountain View. In 1972, Palo Alto became one of the first
communities in California to establish a dedicated bicycle system. Since then, Menlo Park, Palo
Alto and Stanford University have made progress in developing a system of bicycle and
pedestrian routes and facilities to accommodate a growing demand for non-motorized travel.
The existing system consists of three classifications of bicycle facilities:
Class I (bike path) provides an exclusive right-of-way for bicyclists and pedestrians
separate from vehicular traffic and with a minimum number of vehicular crossings.
Class II (bike lane) provides a designated section of the roadway for the exclusive or
semi-exclusive use of bicycles with through travel by motor vehicles or pedestrians
prohibited, but with vehicle parking and cross flows by pedestrians and motorists
permitted.
Class III (bike route) provides bicyclists with facility designated by signs or
permanent markings that is shared by pedestrians and motorists.
Figure 2-4 and Figure 2-5 illustrate the bicycle and pedestrian facilities in the project study area
respectively. There are portions of the Stanford University campus that are bike/pedestrian
access only, which are also identified.
Signalized crossings of El Camino Real, which have pedestrian signals to provide safe
pedestrian/bicycle crossings, are provided at numerous locations in the study area including
Sand Hill Road, Quarry Road, University Avenue, and Embarcadero Road. Bicycles are legal
on all streets in Palo Alto, except freeways, though there are some major streets with narrow
lanes that are not easily shared by bicyclists and motor vehicles.
The City maintains a system of on- and off-road bicycle lanes, routes and paths, which include
14 underpasses or bridges. Palo Alto was the first community to develop the concept of a
bicycle boulevard, which is a low-volume through street where bicycles have priority over

automobiles. Conflicts between bicycles and automobiles are minimized, and bicycle travel time
is reduced by removing stop signs and other impediments to bicycle travel. The bicycle
boulevard is located on Bryant Street. In order to ensure areas of roadways used by bicyclists
are maintained at or above those used by motorists, the City is adjusting its street evaluation
criteria for its Pavement Management Program. In addition, there are several bicycle/
pedestrian/transit only routes in the Stanford University campus, such as Serra Mall.
Pedestrian facilities consist of sidewalks, crosswalks, and many of the facilities for bicycles
discussed above. With some exceptions, the regional connections described for bicyclists also
exist for pedestrians. All Class I bicycle paths and bridges are available to and used by
pedestrians. Sidewalks are present in most parts of Palo Alto although there are some gaps;
Stanford University provides a comprehensive pedestrian/bicycle circulation system that
contributes to the ease of moving to, from, and throughout the campus without the need for an
automobile. There are several policies that the University implements to discourage the use of
vehicles and encourage the use of other travel modes. Some of the policies include:
Financial incentives such as commuter cash, Eco-Pass and Go Pass
Provide academic and residential land uses in close proximity to one another;
Apply campus design concepts and site development standards that facilitate
pedestrian and bicycle use;
Maintain/improve the pedestrian and bicycle circulation system that connect places
of living and work; and
Provide a safe and easily understood system of pedestrian pathways and bikeways.
2.4 Parking
Off-street parking is currently provided for both the Stanford Medical Center and the Stanford
Shopping Center. A total of 5,801 parking spaces are currently provided at the Stanford
Shopping Center for 1,412,368 square feet of commercial area. This is in excess of the city’s
parking code that that requires a minimum of one parking space per 275 square feet of retail
space at a shopping center.
Based on the recent parking survey (Fehr & Peers, September 2007), SUMC (including both the
hospitals and medical offices) currently has about 8,900 parking spaces available including
about 190 on-street parking spaces. Some of these parking spaces are located in areas /
parking structures that serve both SUMC and the university. Approximately 625 of these
spaces are dedicated to the three medical office buildings at 703, 900 and 1101 Welch Road.
The survey was conducted during mid-morning and mid-afternoon. About 6,400 spaces were
occupied during both periods; of which about 4,200 (65 percent) belong to hospital employees
and visitors. The survey also noted that the mid-morning period has a higher parking demand
compared to the mid-afternoon period. The demand at the dedicated medical office parking
area is between 70 percent and 80 percent during the mid-morning peak.

2.5 Transportation Demand Management (TDM)
Transportation demand management refers to actions that reduce work-related drive-alone
vehicle trips. Although a state law was passed in 1995 that prohibited agencies and cities from
requiring mandatory TDM, the City of Palo Alto and Stanford University still voluntarily provide
TDM programs for their employees. Key components of the current TDM program administered
by Stanford are summarized below.
2.5.1 Stanford University Medical Center
SUMC’s TDM program for students, staff, and faculty consists of several elements. The
program is designed to reduce ‘drive-alone’ by encouraging the use of transit, walking and
cycling in order to help meet the “no net new commute trips” goal. This is required by the 1989
and 2000 Santa Clara County General Use Permits.
The TDM program consists of the following elements:
Commute Club:Incentives or perks for those who choose not to drive to work,
e.g.:
í Clean Air Cash or Carpool Credit
í Reserved parking spaces for all carpools/vanpools
í Vanpool subsidies
í Members-only commuter gifts
Marguerite:Free, comprehensive campus shuttle system, open to the public
that connects with local transit and Caltrain. New buses run on
biodiesel fuel and real-time schedules can be viewed on the
web under the Automated Transportation Management System.
VTA Eco-Pass Available free to eligible hospital and university employees,
allows unlimited travel on VTA buses (including express
services), VTA light rail, Dumbarton Express, Highway 17
Express and Monterey-San Jose Express
Line U Stanford
Express:
Free use of East Bay express bus that connects BART, ACE
train and remote park and ride lots (e.g. Ardenwood Farms) to
Stanford.
Bicycle Program Programs that promote and encourage the safe use of bicycles
in and around the campus e.g. bike light giveaways, safety
education programs, bike safety road show, commute planning
/ cycling information, etc.
Vehicle Rental:Hourly, half-day and full-day car rental (through on-campus
Enterprise Rent-a-Car office) available to faculty, staff and
students 18 years and older.
Charter Bus
Services:
Group transportation services are provided during events like
conferences or student activities to allow for alternative forms of
commuting.
Parking Program:Programs to manage parking and discourage driving to and in
campus e.g. no freshman cars, parking permit fees, short-term
parking options etc.
Others:Flexible work options (staggered work hours, compressed work
week etc.), alternative transportation promotional events, one-
on-one commute planning assistance, etc.

3.0 FUTURE CONDITIONS
This section of the TIA provides an evaluation of potential transportation impacts in the Palo
Alto, Menlo Park and East Palo Alto areas associated with the proposed expansion of Stanford
Shopping Center (SSC) and Stanford University Medical Center (SUMC). The impacts are
evaluated relative to the operation of intersections, arterial roadways, freeways, bicycle and
pedestrian transportation, public transportation and transportation demand management (TDM)
strategies.Mitigation measures are recommended which, if implemented, would reduce
impacts of the proposed projects to a less-than-significant level.
The proposed expansion of both the SSC and SUMC would take place in two phases:
x By 2015, SSC and the medical office buildings (MOB) of SUMC at the Hoover Pavilion
site would be fully built-out while the hospital and clinic / medical office portion of the
main SUMC site would be occupied and operated at equivalent to approximately 60
percent build-out. The increase in employees and patients would be 60% of the full
SUMC project build-out.
x By 2025, both SSC and the all of SUMC would be at their full build-out and occupancy
condition.
Project analysis would focus on these two stages of development as well as analysis of the
study intersections, roadway and transportation facilities if only one of these projects is
constructed.
3.1 Project Analysis
Two horizon years, 2015 and 2025, are being used for the future conditions analysis. The
baseline traffic volumes were obtained from the recently updated City of Palo Alto travel
demand forecasting model. This model was developed based on Santa Clara County regional
VTA forecasting model, with ABAG projections of housing and employment data. This model is
consistent with the CMA and MTC models. In 2015, the traffic projections from the travel
demand model result in six intersections operating at LOS E and an additional seven
intersections operating at LOS F without the addition of traffic from either projects. In 2025, the
traffic projections from the travel demand model result in three intersections operating at LOS E
and 12 intersections operating at LOS F in the AM peak hour and five intersections operating at
LOS E and 18 intersections operating at LOS F in the PM peak hour without traffic from either
projects. Traffic congestion prior to the addition of project traffic tends to magnify the project
impacts. For this report, the City of Palo Alto and Santa Clara County CMP
guidelines/significance criteria are used for determining project impacts on all study
intersections; regardless of which agency operates the intersections (City of Palo Alto or other
adjoining jurisdictions). Project impacts are determined by comparing the ‘no project’ scenario
during the different horizon years with the ‘with project’ scenarios. Project impacts for study
intersections within the City of Menlo Park are also determined by using the City of Menlo Park
guidelines and are presented in Appendix A for reference. A total of 63 intersections are
analyzed under the future conditions. The SUMC project would include extending Durand Way

3-2 January 13, 2009
from Sand Hill Road to Welch Road by 2025. Therefore, this new intersection is included in the
2025 analysis. Improvements required for this extension will be privately funded.
The following project scenarios are evaluated for both the typical AM and PM peak hours:
1. Impact of SSC only in 2015 – No Build 2015 traffic volumes + SSC at 100 percent
build-out compared with No Build 2015 traffic volumes
2. Impact of SUMC only in 2015 – No Build 2015 traffic volumes + SUMC at 60 percent
growth compared with No Build 2015 traffic volumes
3. Impact of SSC + SUMC in 2015 – No Build 2015 traffic volumes + SSC at 100
percent build-out + SUMC at 60 percent growth compared with No Build 2015 traffic
volumes
4. Impact of SUMC only in 2025 - No Build 2025 traffic volumes + SUMC at 100
percent build-out compared with No Build 2025 traffic volumes
5. Cumulative Impact of SUMC in 2025 - No Build 2025 traffic volumes + SUMC at 100
percent + SSC at 100 percent build-out compared with No Build 2025 traffic volumes
+ SSC at 100 percent
6. Cumulative Impact of SSC in 2025 - No Build 2025 traffic volumes + SUMC at 100
percent + SSC at 100 percent build-out compared with No Build 2025 traffic volumes
+ SUMC at 100 percent
7. Cumulative Impact of SSC + SUMC in 2025 – No Build 2025 traffic volumes + SUMC
at 100 percent + SSC at 100 percent build-out compared with No Build 2025 traffic
volumes
3.2 Without Project
Traffic volumes from the Palo Alto Citywide forecasting model are used as the future
background volumes. The geometry of the 63 study intersections are presented in Figures 3-1a
through 3-1d and 3-2a through 3-2d for 2015 and 2025 respectively. The intersection numbers
were previously noted in Figure 1-1. The Durand Way extension to Welch Road is reflected in
Figure 3-2 only, as it would not be completed by 2015. With the exception of Durand / Sand Hill
Road (#57) and Durand / Welch (#60), all other intersection geometrics are assumed to remain
consistent between 2015 and 2025. Figures 3-3a through 3-3d and 3-4a through 3-4d show the
traffic volumes at the 63 study intersection in year 2015 and 2025 without the proposed project,
respectively. The intersection performance is tabulated in Tables 3-1 and 3-2. A total of 16
intersections were expected to perform at LOS E or F in 2015 and a total of 25 such
intersections in 2025 without the addition of any traffic from the SUMC or SSC projects. These
intersections are highlighted as well.
During the AM peak hour in 2015, no intersections would operate at LOS E. However, the
following six intersections would perform at LOS F:
El Camino Real / Page Mill – Oregon Expressway (#16) (Palo Alto)
Junipero Serra Boulevard – Foothill Expressway / Page Mill Road (#23) (Palo Alto)
Sand Hill Circle – I-280 / Sand Hill Road (#28) (Menlo Park)

3.3 Project Trip Generation
In order to determine project impacts, the number of trips generated by each project needs to be
calculated. The following sections presents the trip generation for the two projects. The
discussion will focus on the SSC and the SUMC separately.
3.3.1 SSC
The trip generation rates used for SSC are obtained from the ITE Trip Generation, 7th Edition
(ITE, 2000). The SSC would consist of retail (1,592,000 square feet), high-turnover restaurants
(19,200 square feet), high quality restaurants (28,800 square feet) and a 120-room hotel. This
expansion is expected to be fully completed by 2015.
Stanford University Medical Center and Stanford Shopping Center
3.0 FUTURE CONDITIONS
3-28 January 13, 2009
The retail area of 1,592,000 square feet includes the existing area of 1,400,000 square feet.
Table 3-3 presents the trip generation calculated for each of the land uses. Regression
equations are used to estimate project traffic volumes. Appendix B lists the regression
equations and trip rates used. Regression equations indicate that shopping centers generate
traffic at a decreasing rate as the facility size expands. Newly generated project traffic is the net
difference between the projected trips for the new total area and the projected trips for the
existing area. For this study, high-turnover restaurants are included in the shopping center area
for the trip generation rate calculations whereas high-quality restaurants and the hotel are
calculated separately. The assumption is that traffic to a high-quality restaurant is independent
of the surroundings of that facility.

*Includes 1,400,000 square feet of existing area, 192,000 square feet of new retail and 19,200 square feet of high-turnover
restaurant.
Adjustments were made to the trips generated to account for pass-by and diverted trips to the
shopping center during the PM peak hour. Pass-by trips are made as intermediate stops on the
way from an origin to a primary destination without a route diversion. They are trips attracted to
the shopping center from traffic already passing the project site on an adjacent street with direct
access to the project site. Based on the pass-by trip regression equation from the Trip
Generation Handbook (ITE, 2001), it is estimated that about 10 percent of the expected trips
generated from the retail portion (including high-turnover restaurants) would be pass-by trips.
Another approximately 15 percent of the expected SSC retail trips would be diverted trips.
Diverted trips are trips that are attracted from roadways within the vicinity of the generator (the
shopping center) but that require a diversion from that roadway to another to gain access to the

site. Diverted trips consist of traffic that is already on the roadway network. Therefore, it was
removed from trip generation. However, since it travels through intersections adjacent to the
project area, it was assigned to intersections surrounding the project. The revised trips
generated by SSC are presented in Table 3-4. The SSC project trips were further adjusted for
‘Hotel/Retail Mixed-Use’ reduction of 10% (hotel trips) according to the CMP recommendation.

3.3.2 SUMC
The SUMC consists of Stanford University School of Medicine, Stanford Hospital and Clinics,
the Lucile Packard Children’s Hospital and medical office buildings (MOB). As part of the
proposed expansion, several existing MOB (119,900 square feet) would be demolished. This
would be taken into account when calculating the trips generated by the project. Hoover
Pavilion would be renovated and square footage would be added to this site for the MOBs
(144,000 square feet). In addition, adjustment, or ‘right-sizing’ space credit, is applied to the
proposed expansion area for the hospitals to better reflect the facilities practical use. The
hospitals are currently undersized relative to the services they provide. Part of the proposed
expansion is needed to better accommodate the existing uses which would have no impact on
the trips generation. This is ‘right-sizing’ adjustment. Net proposed expansion for Stanford
Hospital and Clinics and Lucile Packard Children’s Hospital is 854,970 square feet.
Trip generation rates for SUMC were determined using data collected from existing facilities.
Driveway counts were conducted at 20 parking areas serving the SUMC during the AM (7:00-
9:00) and PM (4:00-6:00) peak hours. Trip generation rates were then calculated based on the
traffic volumes and the size of existing buildings. The hospitals would be operating 60 percent
of the full build-out in 2015 and the trips generated are presented in Table 3-5. Trips generated
for a full build-out (100 percent) of the SUMC in 2025 are shown in Table 3-6. Appendix C and
D contains details of the review and validation of the hospital trip generation statistics.

1. Trip generation based on survey data from Fehr and Peers, 2007, adjusted by AECOM according to
white paper analysis contained in Appendix C
After determining the number of trips generated by the project, they are distributed and
assigned to all study intersections. Distribution is divided into regional and local patterns to

more accurately reflect the origins of the trips. Appendix E presents the details of this trip
distribution. SUMC trips are divided into 75 percent regional and 25 percent local. These
percentages were derived from existing employee zip code data. A majority of peak hour traffic
is associated with employee travel. However, some hospital related peak hour travel will be
made by patients or visitors. The travel pattern of patients and visitors is expected to be similar
to that of employees during the peak hour analysis periods. SSC trips are divided into 30
percent regional and 70 percent local; determined from the Palo Alto Citywide travel demand
forecasting model. Figures 3-5 and 3-6 show the percentage distribution for SUMC and Figures
3-7 and 3-8 show the percentage distribution for SSC. The project trips were then assigned to
each study intersection based on the distribution percentages. Figures 3-9a through 3-9d to 3-
12a through 3-12d present the ‘project only’ volumes at each intersection under the different
project scenarios.
3.4 Project Impacts
Project impacts on study intersections are presented in the LOS comparisons Tables 3-7 to 3-
13 where the adversely affected intersections have been highlighted. All intersections are
evaluated based of City of Palo Alto criteria. Project impacts on freeway segments and
residential roadways are also discussed. In particular, project impacts on several roadways in
Menlo Park are evaluated based on ADT according to the City of Menlo Park significance
criteria. The significance criteria were previously presented in Section 1.8.
3.4.1 Impact of SSC only in 2015
No Build 2015 traffic volumes + SSC at 100 percent build-out compared with No Build
2015 traffic volumes
The traffic volumes for this scenario are shown in Figures 3-13a through 3-13d. The
results of the analysis are included in Table 3-7.
The SSC is assumed to be fully built in this scenario. As presented in Table 3-7, during
the AM peak, no intersections would be adversely impacted by the project. This scenario
is expected to have the least impact as it generates the smallest number of trips. As a
retail center, it is not expected to generate many trips early in the day. Most retail
employees would not start work until after the highway peak and shoppers would not
arrive during the AM peak hour. Six intersections would be adversely impacted by the
proposed SSC expansion in the PM peak:

x El Camino Real / University Avenue (#10) – Palm Drive – LOS changes from D to
E and is considered adversely impacted.
x Middlefield Road / Lytton Avenue (#19) - LOS remains at F but the average
critical delay increased by 4 seconds and the V/C increased by 0.012. This
intersection is significantly affected by the project.
x Junipero Serra Boulevard / Campus Drive West (#26) – LOS remains at E but the
average critical delay increased by 18.8 seconds and the V/C increased by
0.046. This intersection is significantly affected by the project.
x Junipero Serra Boulevard / Alpine-Santa Cruz Avenue (#27) - LOS changes from
D to E and is considered adversely impacted.
x Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of Palo
Alto has not adopted specific criteria for impacts at unsignalized intersections.
Therefore if traffic signal warrants are met, additional traffic through the
intersection would constitute a significant impact. Traffic signal warrants at this
intersection are met at baseline conditions as well as with project.
x Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F but the
average critical delay increased by 6.6 seconds and the V/C increased by 0.016.
This intersection is significantly affected by the project.
3.4.2 Impact of SUMC only in 2015
No Build 2015 traffic volumes + SUMC at 60 percent of full build-out occupancy
compared with No Build 2015 traffic volumes
The traffic volumes for this scenario are shown in Figures 3-14a through 3-14d. The
results of the analysis are included in Table 3-8. For this scenario, SUMC is at 60
percent occupancy of the full build-out. As seen in Table 3-8, four intersections would
be adversely impacted by the proposed SUMC project during the AM peak:
x El Camino Real / Galvez (#11) - LOS changes from D to E with the project
and is considered significantly impacted.
x El Camino Real / Page Mill-Oregon Expressway (#16) - LOS remains at F
with or without the proposed project. The average critical delay increased by
6.1 seconds and the V/C increased by 0.016. This intersection is significantly
affected by the project.
x Alpine / I-280 NB Off-Ramp (#62) (unsignalized) - LOS remains at F. The
City of Palo Alto has not adopted specific criteria for impacts at unsignalized
intersections. Therefore if traffic signal warrants are met, additional traffic
through the intersection would constitute a significant impact. Traffic signal
warrants are met at this intersection.
x Alpine / I-280 SB Off-Ramp (#63) (unsignalized)- LOS remains at F. The City
of Palo Alto has not adopted specific criteria for impacts at unsignalized
intersections. Therefore if traffic signal warrants are met, additional traffic

through the intersection would constitute a significant impact. Traffic signal
warrants are met at this intersection.
During the PM peak hour, eight intersections would be adversely affected. The eight
affected intersections are:
x El Camino Real / University Avenue (#10) - LOS changes from D to E with
the project and is considered significantly impacted.
x El Camino Real / Page Mill-Oregon Expressway (#16) - LOS remains at F.
The average critical delay increased by 4 seconds and the V/C increased by
0.01. This intersection is significantly affected by the project.
x Middlefield Road / Willow Road (#18) -LOS changes from E to F with the
project. The average critical delay increased by 8.7 seconds and the V/C
increased by 0.027. This intersection is significantly affected by the project.
x Middlefield Road / Lytton Avenue (#19) - LOS remains at F. The average
critical delay increased by 5.2 seconds and the V/C increased by 0.013. This
intersection is significantly affected by the project.
x Junipero Serra Boulevard / Page Mill Road (#23) - LOS remains at F. The
average critical delay increased by 4.3 seconds and the V/C increased by
0.01. This intersection is significantly affected by the project.
x Junipero Serra Boulevard / Alpine / Santa Cruz (#27) - LOS changes from D
to E with the project and is considered significantly impacted.
x Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of
Palo Alto has not adopted specific criteria for impacts at unsignalized
intersections. Therefore if traffic signal warrants are met, additional traffic
through the intersection would constitute a significant impact. Traffic signal
warrants are met at this intersection.
x Alpine Road / I-280 NB Off-Ramp (#62) (unsignalized) - LOS remains at F.
The City of Palo Alto has not adopted specific criteria for impacts at
unsignalized intersections. Therefore if traffic signal warrants are met,
additional traffic through the intersection would constitute a significant impact.
Traffic signal warrants at this intersection are met at baseline conditions as
well as with project.
3.4.3 Impact of SSC + SUMC in 2015
No Build 2015 traffic volumes + SSC at 100 percent build-out + SUMC at 60 percent
occupancy of full build-out compared with No Build 2015 traffic volumes
The traffic volumes for this scenario are shown in Figures 3-15a through 3-15d. The
results of the analysis are included in Table 3-9.

3.0 FUTURE CONDITIONS
3-72 January 13, 2009
For this scenario, SSC would be fully built-out while SUMC would be at 60 percent build-
out. Five intersections would be affected during the AM peak hour as shown in Table 3-
9:
x El Camino Real / Galvez (#11) – LOS changes from D to E and is therefore
considered significantly impacted by the projects.
x El Camino Real / Page Mill-Oregon Expressway (#16) - LOS remains at F.
The average critical delay increased by 7.4 seconds and the V/C increased by
0.02. This intersection is significantly affected by the project.
x Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F. The
average critical delay increased by 4.7 seconds and the V/C increased by
0.015. This intersection is significantly affected by the projects.
x Alpine Road / I-280 NB Off-Ramp (#62) (unsignalized) - LOS remains at F.
The City of Palo Alto has not adopted specific criteria for impacts at
unsignalized intersections. Therefore if traffic signal warrants are met,
additional traffic through the intersection would constitute a significant impact.
Traffic signal warrants at this intersection are met at baseline conditions as
well as with project.
x Alpine Road / I-280 NB Off-Ramp (#63) (unsignalized) - LOS remains at F.
The City of Palo Alto has not adopted specific criteria for impacts at
unsignalized intersections. Therefore if traffic signal warrants are met,
additional traffic through the intersection would constitute a significant impact.
Traffic signal warrants at this intersection are met at baseline conditions as
well as with project.
In the PM peak hour, a total of 11 intersections would be significantly impacted by the
proposed project:
x El Camino Real / Valparaiso (#1) Avenue - LOS changes from D to E and is
therefore considered significantly impacted by the projects.
x El Camino Real / University Avenue (#10) - LOS changes from D to E and is
therefore considered significantly impacted by the projects.
x El Camino Real / Page Mill-Oregon Expressway (#16) - LOS remains at F.
The average critical delay increased by 6.5 seconds and the V/C increased by
0.016. This intersection is significantly affected by the projects.
x Middlefield Road / Willow Road (#18) -LOS changes from E to F with the
project. The average critical delay increased by 11.6 seconds and the V/C
increased by 0.036. This intersection is significantly affected by the projects.
x Middlefield Road / Lytton Avenue (#19) - LOS remains at F. The average
critical delay increased by 9 seconds and the V/C increased by 0.024. This
intersection is significantly affected by the projects.

x Junipero Serra Boulevard / Page Mill Road (#23) - LOS remains at F. The
average critical delay increased by 7.3 seconds and the V/C increased by
0.016. This intersection is significantly affected by the projects.
x Junipero Serra Boulevard / Campus Drive West (#26). - LOS remains at E.
The average critical delay increased by 21.6 seconds and the V/C increased
by 0.053. This intersection is significantly affected by the projects.
x Junipero Serra Boulevard / Alpine-Santa Cruz Avenue (#27) - LOS changes
from D to E and is therefore considered significantly impacted by the projects.
x Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of Palo
Alto has not adopted specific criteria for impacts at unsignalized intersections.
Therefore if traffic signal warrants are met, additional traffic through the
intersection would constitute a significant impact. Traffic signal warrants are
met at this intersection.
x Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F. The
average critical delay increased by 10.9 seconds and the V/C increased by
0.026. This intersection is significantly affected by the projects.
x Alpine Road / I-280 NB Off-Ramp (#62) (unsignalized) - LOS remains at F.
The City of Palo Alto has not adopted specific criteria for impacts at
unsignalized intersections. Therefore if traffic signal warrants are met,
additional traffic through the intersection would constitute a significant impact.
Traffic signal warrants at this intersection are met at baseline conditions as
well as with project.
3.4.4 Impact of SUMC only in 2025
No Build 2025 traffic volumes + SUMC at 100 percent build-out compared with No Build
2025 traffic volumes
The traffic volumes for the scenario are shown in Figures 3-16a through 3-16d. The
results of the analysis are included in Table 3-10.
In 2025, SUMC is assumed to be fully built-out and occupied. As such, trips to/from
SUMC would increase. A total of 16 intersections would be negatively impacted by the
proposed expansion during the AM peak hour as presented in Table 3-10:
x El Camino Real / Valparaiso Avenue (#1) - LOS remains at E. The average
critical delay increased by 8.2 seconds and the V/C increased by 0.023. This
intersection is significantly affected by the project.
x El Camino Real / Ravenswood Avenue (#3) - LOS remains at F. The
average critical delay increased by 14 seconds and the V/C increased by
0.034. This intersection is significantly affected by the project.
x El Camino Real / University Avenue (#10) - LOS changes from D to E and is
therefore considered significantly impacted by the project.

3.4.5 Cumulative Impact of SUMC in 2025
No Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-out
compared with No Build 2025 traffic volumes + SSC at 100 percent (Base A)
Stanford University Medical Center and Stanford Shopping Center
3.0 FUTURE CONDITIONS
3-83 January 13, 2009
The traffic volumes for this scenario are shown in Figures 3-17a through 3-17d. The
results of the analysis are included in Table 3-11. As noted on Table 3-11, a new base
for comparison, Base A, is used. Base A represents the 2025 No Build volumes plus the
full development of SSC.
In this scenario, it is assumed that the SSC has been completed in 2015 and is
considered part of the background traffic in 2025. The SUMC project volumes are
added on to determine the cumulative impact of SUMC in 2025.
A total of 16 intersections would be impacted during the AM peak period as shown in
Table 3-11:
x El Camino Real / Valparaiso (#1) - LOS remains at E. The average critical
delay increased by 8.5 seconds and the V/C increased by 0.023. This
intersection is considered significantly affected by the projects.
x El Camino Real / Ravenswood (#3) - LOS remains at F. The average critical
delay increased by 13.8 seconds and the V/C increased by 0.034. This
intersection is considered significantly affected by the projects.
x University Avenue / El Camino Real (#10) – LOS changes from D in the base
scenario to E with SUMC and is therefore considered significantly impacted.
x El Camino Real / Embarcadero-Galvez (#11) - LOS remains at F. The
average critical delay increased by 9.9 seconds and the V/C increased by
0.025. This intersection is considered significantly affected by the projects.

x Arboretum / Galvez (#37) (unsignalized) - LOS changes from D in the base
scenario to E and is therefore considered significantly impacted by the project.
In addition, the City of Palo Alto has not adopted specific criteria for impacts at
unsignalized intersections. Therefore if traffic signal warrants are met,
additional traffic through the intersection would constitute a significant impact.
Traffic signal warrants are met at this intersection.
x Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F but the
average critical delay increased by 6.3 seconds and the V/C increased by
0.017. This intersection is considered significantly affected by the projects.
x Alpine Road / I-280 NB Off-Ramp (#62) (unsignlized) - LOS remains at F. The
City of Palo Alto has not adopted specific criteria for impacts at unsignalized
intersections. Therefore if traffic signal warrants are met, additional traffic
through the intersection would constitute a significant impact. Traffic signal

3.4.6 Cumulative Impact of SSC in 2025
No Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-out
compared with No Build 2025 traffic volumes + SUMC at 100 percent (Base B)
The traffic volumes for this scenario were previously shown in Figures 3-17a through
Figure 3-17d. The analysis results are shown in Table 3-12. As noted on Table 3-12, a
new base for comparison, Base B, is used. Base B represents the 2025 No Build
volumes plus full development of SUMC.
Only one intersection is adversely impacted by the project under this cumulative
scenario comparison in the AM peak:
x Santa Cruz / Sand Hill (#30) - LOS remains at LOS F but the critical average
delay increased by 4.6 seconds and V/C increased by 0.011. This is
considered significantly impacted by the projects.
There are eleven intersections that would be adversely impacted by the project during

x Junipero Serra Boulevard /Campus Drive West (#26) - LOS remains at F but
the average critical delay increased by 22.8 seconds and the V/C increased
by 0.045. This intersection is considered significantly affected by the
projects.
x Junipero Serra Boulevard / Santa Cruz-Alpine (#27) - LOS remains at F but
the average critical delay increased by 11.7 seconds and the V/C increased
by 0.027. This intersection is considered significantly affected by the
projects.
x Santa Cruz / Sand Hill Road (#30) - LOS remains at F but the average critical
delay increased by 8.9 seconds and the V/C increased by 0.023. This
intersection is considered significantly affected by the projects.
x Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of
Palo Alto has not adopted specific criteria for impacts at unsignalized
intersections. Therefore if traffic signal warrants are met, additional traffic
through the intersection would constitute a significant impact. Traffic signal
warrants are met at this intersection.
x Middlefield / Ravenswood (#46) - LOS remains at F but the average critical
delay increased by 7.4 seconds and the V/C increased by 0.017. This
intersection is considered significantly affected by the projects.
3.4.7 2025 with SSC and SUMC – Cumulative of SSC + SUMC
No Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-out
compared with No Build 2025 traffic volumes
This is the worst-case scenario as both SSC and SUMC are at full build-out. While
lesser trips would be generated for the SSC during the AM peak hour due to the land
use, the PM peak hour results in this scenario having the highest number of trips
generated. 16 and 21 intersections would be adversely affected during the AM and PM
peak hour respectively. The traffic volumes for this scenario were previously shown in
Figures 3-17a through 3-17b. The analysis results are shown in Table 3-13.
During the AM peak hour, the affected intersections as shown in Table 3-13 are:
x El Camino Real / Valparaiso Avenue (#1) - LOS remains at E but the average
critical delay increased by 9.2 seconds and the V/C increased by 0.025. This
intersection is considered significantly affected by the projects.
x El Camino Real / Ravenswood Avenue (#3) - LOS remains at F but the
average critical delay increased by 15.7 seconds and the V/C increased by
0.038. This intersection is considered significantly affected by the projects.
x El Camino Real / University Avenue (#10) - LOS changes from LOS D to LOS
E and is therefore considered significantly impacted.
x El Camino Real / Embarcadero-Galvez (#11) - LOS remains at F but the
average critical delay increased by 11.1 seconds and the V/C increased by
0.028. This intersection is considered significantly affected by the projects.

3.5 Project Impact Analysis Summary
A summary of project impacts for all the project scenarios is presented in Table 3-14. For the
different ‘bases’ used for comparison, intersections performing at LOS E or F are highlighted in
‘diamond’. Intersections exceeding the criteria thresholds and considered as adversely affected
by the project are highlighted by the different shapes. Squares are for the SSC, dots are for the
SUMC and triangles are for the combined effect of SSC and SUMC. Appendix F shows the
Traffix calculations for all intersections in 2015 and 2025.
Project impacts in 2015 are less than in 2025. First, the background traffic is lower in 2015 and
SUMC would only be equivalent to 60 percent build-out. In addition, impacts during the AM
peak are less than during the PM peak. Less employees and shoppers at the SSC would be
commuting during the AM peak whereas a larger number of SSC shoppers would be traveling
during the PM peak hour. This can be seen clearly from column B of Table 3-14 where no
intersections would be negatively impacted in 2015 during the AM peak. Six intersections would
be impacted during the PM peak due to the SSC project, of which three are in the City of Palo
Alto. Given that part of the study area is in the City of Menlo Park and some intersections are
under the jurisdiction of the County, the summary table presents the total number of
intersections that would be adversely impacted by the project and also notes the number of
intersections impacted in Palo Alto. A similar trend is seen for the SUMC. Four Palo Alto
intersections would be impacted during the AM peak hour in 2015 and five out of eight impacted
intersections are in Palo Alto. Under the effect of both the SSC and SUMC, five intersections
would be adversely affected in the AM peak hour by the project, with four of these intersections
being in Palo Alto. During the PM peak hour, 11 intersections would be affected of which seven
are in Palo Alto.
In 2025, there are different comparison scenarios dependent upon the completed parts of the
project in 2015. If SSC has been built in 2015, its generated trips would be part of the
background traffic (New Base A). The effect of SUMC in both the AM and PM peak hours are
presented in Columns M and T respectively. A total of 16 intersections would be affected in the
AM peak hour and 20 in the PM peak hour. The number of affected intersections in Palo Alto is
eight and ten respectively. On the other hand, if the SSC did not get built in 2015, the effect of
SUMC alone is presented in Columns J and Q for the AM and PM peak hours respectively. Of
the 16 impacted intersections in the AM peak hour, eight are in Palo Alto. Of the 18 impacted
intersections in the PM peak hour, nine are in Palo Alto. In order to determine the effect of the
SSC project in 2025, comparison is made with the scenario where SUMC is part of the
background as presented in Columns O and V. Similar to the trend in 2015, impact during the
AM peak hour is minimal with only one intersection in Menlo Park being affected. During the
evening peak, eleven intersections would be affected with three in Palo Alto.
3.6 Freeway Analysis
Based on the CMP requirements for freeways, Table 3-15 presents the number of project trips
on the different freeway segments within the study area. The number of project trips added
onto the freeway would determine if a freeway analysis is required. If the added project trips are
more than one percent of the freeway capacity for a freeway section currently operating at LOS
F, a freeway assessment would be necessary. The capacity for both US 101 and I-280 is 2,300

vehicles per hour per lane (vphpl) as they have six lanes or more in each of the segments
covered. HOV lanes have been included in this calculation. There is one HOV lane on both
northbound and southbound of US 101 but none along the segments of I-280 within the study
area. For the purpose of this study, the worst case of added project trips is being considered;
the combined effect of SSC and SUMC would see the highest number of project trips being
added. It can be seen from the Table 3-15 that the number of project trips expected on the
regular freeway lanes would be less than one percent for all study segments. As such, no
further analysis is necessary. It is therefore inductive that the individual SSC and SUMC project
would not have adverse impact on these study freeway segments.

3.7 Residential Roadway Segment Analysis (TIRE Index)
This section looks at the project impact on residential streets in Palo Alto and Menlo Park. A
street is considered impacted if the TIRE Index increases by 0.1. The various project scenarios
are compared to the base to determine any project impact. No residential roadway segments
would be impacted in any of the 2015 project scenarios as seen in Table 3-16.

In 2025 however, addition project traffic under the cumulative effect of SSC and SUMC would
significantly affect the section of Hamilton Avenue between Chaucer Street and Lincoln Avenue
as presented in Table 3-17. With a ‘no project’ ADT volume of 2,193 along Hamilton Avenue
(between Chaucer Street and Lincoln Avenue), an increase of 515 vehicles in ADT would
constitute a change of 0.1 in the TIRE Index. The cumulative ADT volume of the SSC and the
SUMC projects is 515 which would be considered a significant impact as the TIRE Index would
change. However, the TIRE index is based in ADT not peak hour traffic. While peak hour traffic
may be diverted to Hamilton Avenue, the same proportion of non-peak hour traffic would
probably not be diverted. Therefore, the ADT values may be overstated. The other residential
road segments would not be adversely by the project in 2025 as the increase in ADT volume
does not bring about any change in the TIRE Index. Table 3-17 also represents the 2025
cumulative condition. Mitigation of impacts to residential streets requires a reduction in traffic
volume. The impact to Hamilton Avenue is caused by the cumulative effect of both projects in
2025. SUMC constitutes 92 percent of the traffic and SSC contributes 8 percent. The effect of
each project individually is comparable to these percentages.
3.7.1 Menlo Park Roadway Analysis
As part of the City of Menlo Park evaluation criteria, selected roadways are being
evaluated to determine the effect of the proposed projects. Average daily traffic (ADT) of
these roadways were calculated for the different scenarios and compared to the ‘no
project’ scenario to determine project impact. Table 3-18 presents the analysis results.
This data is presented for informational purpose since the City of Palo Alto does not use
this evaluation methodology. The TIRE index for most of these roadway segments
would not be significantly impacted as discussed later in this section.
With the SSC project in 2015 as presented in Table 3-18, Sand Hill Road (east of Santa
Cruz), Willow Road (east of Middlefield Road) and Ravenswood Avenue (east of El
Camino Real) would be impacted by the project. With the SUMC project, two more
roadways would be affected by the proposed project. These are Marsh Road (west of
US 101) and Alpine Road (west of Junipero Serra Boulevard). With both the SSC and
SUMC projects, the same five roadways would be significantly impacted in 2015.

In 2025, with the SSC project, four roadway segments would be significantly affected.
These are: Sand Hill Road (east of Santa Cruz), Willow Road (east of Middlefield Road),
Middlefield Road (north of Ravenswood Avenue) and Ravenswood Avenue (east of El
Camino Real). With the SUMC project, two more roadway segments would be adversely

impacted by the project. These two roadways are Marsh Road (west of US 101) and
Alpine Road (west of Junipero Serra Boulevard). With both the SSC and SUMC
projects, the same six roadways would be significantly impacted in 2025.
The cumulative impacts of the projects on the roadways in 2025 are also presented in
Table 3-18. It can be seen that the SUMC project would significantly affect six roadway
segments (Base A). They are Marsh Road (west of US 101), Sand Hill Road (east of
Santa Cruz), Willow Road (east of Middlefield Road), Alpine Road (west of Junipero
Serra Boulevard), Middlefield Road (north of Ravenswood Avenue) and Ravenswood
Avenue (east of El Camino Real). These same roadway segments, except Marsh Road
and Alpine Road, would also be adversely impacted by the cumulative effect of the SSC
project (Base B).
These roadway segments were also evaluated using the TIRE index, consistent with the
City of Palo Alto procedures. None of these roadway segments exceeded the TIRE
index thresholds as seen in Table 3-19. Therefore, according to City of Palo Alto
standards, no roadway segments are considered to be impacted to a significant level.
3.8 Parking Analysis
The following sections looked at the parking provisions planned for the SUMC and SSC.
Comparisons are made with the parking rates stated in the 3rd Edition of ITE Parking Generation
(ITE, 2004) as well as the requirements listed in the Palo Alto City Zoning Ordinance to
determine if the project has sufficient parking.
3.8.1 SUMC
The proposed SUMC expansion includes the Stanford Hospital and Clinics (SHC), the
Lucile Packard Children’s Hospital (LPCH) and Medical Office Buildings (MOB). The
SHC project component included 1,100,000 square feet of new hospital space and
429,000 square feet of new clinic space. To accommodate this new development,
356,875 square feet of hospital space and 308,176 square feet of clinic space would be
removed. The new hospital space is reduced by 320,000 square feet to account for
“right sizing”. “Right sizing” adjustment accounts for space changes in the medical
profession that does not accommodate additional patients or staff and therefore does not
generate additional traffic. The net development of SHC is 228,200 square feet of
hospital space and 315,700 square feet of clinic space for a total of 543,900 square feet
of additional development. Details of the parking evaluation are presented in Appendix
G1.
The LCPH project component includes 471,300 square feet of new hospital space and
50,000 square feet of new clinic space. “Right sizing” for LCPH represents a 126,000-
square foot reduction. The net development for LCPH is 345,300 square feet of hospital
space and 50,000 square feet of clinic space, for a total of 395,300 square feet of
additional development. Both the SHC and LPCH have a net additional area of 854,670
square feet combined. The MOB component of the project consists of the removal of
56,300 square feet of MOB at 701 Welch Road, 23,500 square feet at 703 Welch Road,

would be operating at a level equivalent to 60% of the full project build-out. Using the
parking demand rate determined through the survey conducted on existing parking
conditions, 913 spaces would be needed for the hospitals in 2015 and 1,522 spaces
would be needed in 2025. Taking into account a 10-percent supply buffer to ensure that
drivers are able to locate parking spaces without excessive re-circulating through the
parking area, the parking demand at hospital is calculated to be 1,005 in 2015 and 1,674
in 2025. Taking away spaces available from current vacancies, new parking spaces
needed for the hospital would be 747 in 2015 and 1,416 in 2025. This is similar to the
City’s parking ordinance requirements and is greater than the parking demand
calculated according to ITE statistics. For the MOB, 577 spaces would be needed to
meet the parking demand for both horizon years. Similarly, taking into account a 10-
percent supply buffer to ensure that drivers are able to locate parking spaces without
excessive re-circulating through the parking area, the parking demand at MOB stands at
635 in both 2015 and 2025. The total demand for SUMC in 2015 is estimated to be
1,382 spaces and 2,051 in 2025. The proposed number of parking spaces is 2,180 in
2015 and the proposed provision is 2,985 spaces in year 2025. These spaces would be
distributed around the five parking structures in the hospital area. The total parking
supply in 2025 is allocated at 2,051 for SUMC and 932 as replacement parking for
existing spaces demolished for project construction. The replacement parking is
separated in 871 spaces removed plus a 10 percent vacancy factor. Appendix G2
summarizes the parking demand and replacements. Therefore, proposed parking
equals estimated parking demand plus a 10 percent buffer.
3.8.2 SSC
The SSC project is divided into three main categories. There is a 120-room hotel, a high
quality restaurant and the regular retail section that includes high turnover restaurants.
The size of the retail area and high quality restaurant is a total of 240,000 square feet.
Table 3-22 presents the parking calculations for each of the different uses. A total of
1,199 new parking spaces are being proposed for the SSC project, making the total
number of parking spaces for the SSC 7,000. This number is lower than the 10,362
spaces required based on the City’s parking ordinance and the 8,134 spaces calculated
using ITE parking generation rates. However, the existing shopping center has 5,801
parking spaces, whereas the City code projects a demand of 7,061 spaces for existing
uses. The difference between these two values, added to the proposed 7,000 spaces
results in 8,260 spaces, or approximately equal to the ITE estimated demand. Assuming
the percent shared parking results in parking supply slightly less than ITE demand figure
would indicate. Given the SSC is located near a major transit hub, parking supply meets
estimated demand. Details are provided in Appendix G3.
3.9 Project Site Local Circulation Analysis
The SUMC project will result in several changes to local access and circulation. While to a
great extent, the project will rely on the existing roadway network, there are changes to that
network and will enhance and modify local access, including improving the capacity of Welch

Road, adding extensions on Durand Way, Quarry Road, and Roth Way, and increasing the
capacity of Pasteur Drive. The following discusses the individual components of the roadway
network.
Welch Road
Welch Road between Quarry Road and Pasteur Drive currently has 29 driveways, of which 4
are closed. The remaining 25 driveways provide for a combination of inbound, outbound, and
two-way access to the individual land parcels along Welch Road. The current traffic volumes
are 11,375 vehicles per day, as measured in Fall 2008. Pedestrian crossings of Welch Road
are concentrated at three locations, near the Stanford Barn and on both sides of the LPCH
parking structure access. Hourly pedestrian volume at these three crossings was observed at
approximately 200 persons during the midday, the time of greatest pedestrian activity. None of
the three pedestrian crossings are signalized; one is controlled by a crossing guard. Therefore,
pedestrians frequently cross Welch Road which affects the traffic capacity of Welch Road.
Because of the numerous driveways, overlap of left turns occurs at 3 locations. Overlapping left
turns tend to increase congestion by restricting through traffic when opposing left turn queues
block each other. The existing constraints to capacity on Welch Road include the side friction
caused by numerous driveways and slow traffic turning into and out of the driveways, left turns
blocking the through traffic movements and frequent pedestrian crossings. The ‘with project’
scenario includes some modifications to Welch Road to improve traffic flow and accommodate
the future traffic volumes from the hospital expansion. Under the With Project scenario, Welch
Road will be a 3-lane roadway with on-street bike lanes. There will be one through lane in each
direction (11-foot through lanes), with a two way left turn lane in the center (12-foot center left
turn lane). The bike lanes will be six feet wide, including the gutter. Right turns into driveways
will occur from the through lanes, however, left turns will be removed from the through lanes.
The future traffic volumes on Welch Road are projected at 14,750 vehicles per day. This level
of traffic on a two-way roadway with a continuous two way left turn lane in the median is
approaching the capacity of the roadway. The three pedestrian crossings are proposed to be
combined into one or two locations. The main pedestrian crossing at the LPCH access will be
signalized. Signalization of the pedestrian crossing will improve the capacity of Welch by
concentrating crossings into specific time segments, rather than the current operation where
pedestrians cross individually or in smaller groups nearly continuously. The three locations with
overlapping left turns are removed. The conflict at 703 and 730 Welch Road is eliminated with
the realignment of the driveways. The conflict at 780/800 Welch and 777/801 Welch is
eliminated by closing a driveway. The conflict at 1110 Welch and 1101 Welch is eliminated by
moving the access to 1101 Welch onto Durand. Driveways in the vicinity of the Quarry Road
intersection would be restricted to right in and right out only. A center barrier median will be
constructed between Quarry Road and the entrance to LPCH to prevent left turns to and from
the driveways. The barrier median will also improve the capacity of Welch Road. A computer
simulation was made of traffic and pedestrian movements along Welch Road. That simulation
demonstrated that the modified roadway design proposed as part of the project improves traffic
flow.

the hospital project build-out in 2025. The roadway is proposed as a four-lane cross section,
with two lanes in each direction and on-street bike lanes. Travel lane widths are 11 feet and the
bike lanes are 6 foot, including the gutter. This design will enable left turn queues to extend
from Sand Hill Road back to Welch Road, or the reverse. Both Sand Hill/Durand and
Welch/Durand would be signalized. At Sand Hill Road, the two westbound lanes on Durand
Way should be a left and a through/right. This lane striping will keep the queues from extending
back to the Welch Road intersection. At Welch Road the two lanes on Durand Way should be
striped for a right and a through/left. The two traffic signals on Durand Way should be
interconnected. The signal cycles on Sand Hill Road range from 120 to 140 seconds to
maximize through travel on Sand Hill Road. The signal cycle lengths on Welch will not be as
long. Instead, the cycle lengths at Welch/Durand should one-half of those on Sand Hill to
maintain coordination. The extension of Durand Way to Sand Hill Road provides traffic relief to
Pasteur Drive and to Welch Road. Durand Way was included in the computer simulation and
acceptable traffic operations are expected. Queue lengths were also calculated using
TRAFFIX. Adequate storage is provided to accommodate vehicles between these two
intersections.
Quarry Road Extension
An extension of Quarry Road is proposed to provide access to hospital parking. At the
approximate location where existing Quarry Road turns to connect to Campus Drive West, the
Quarry Road extension will continue south to Roth Way. The Quarry Road extension will be a
two-lane roadway with on-street bike lanes. Lane widths will be 11 feet with 6-foot bike lanes
including the gutter. The connection to existing Quarry Road would be stopped controlled for
the Quarry Road extension leg.
Roth Way
Roth Way will connect Campus Drive West to the Quarry Road extension. This connection will
provide access to a proposed parking structure. Roth Way will be a two-lane roadway with on-
street bike lanes. The travel lanes will be 11 feet and the bike lanes 6 feet including the gutter.
Pasteur Drive
The two legs of Pasteur Drive currently exist and provide access to the Medical Center and to
the underground parking garage. On-street parking will be removed from Pasteur Drive and the
roadway will provide two lanes of travel in each direction with on-street bike lanes. Travel lanes
will be 11 feet with 6-foot bike lanes including the gutter.

3.0 FUTURE CONDITIONS
3-115 January 13, 2009
A private street connection is proposed between the intersection of Roth Way/Quarry Road
Extension and Pasteur Drive. Stanford has indicated that this service road would be for limited
access (emergency vehicle, transit, service). This roadway makes a connection between Sand
Hill Road at Pasteur Drive and Campus Drive West at Roth Way. As such it enhances the grid
pattern of the local street network. Local circulation could be improved with this roadway open
to all traffic as a public street.
3.10 Transit Impacts
The SUMC and SSC projects cause an increase in the level of traffic congestion at several
locations throughout the study area. While mitigation measures such as roadway improvements
and TDM measures have been identified to alleviate some of the traffic impacts, implementation
of many of the traffic improvements are either infeasible or undesirable and TDM measures do
not fully mitigate the traffic impacts. Impacts to transit service in the study area because of
congested intersections are considered a significant impact according to City of Palo Alto
criteria and occur as a result of both projects by 2015. The impacts increase as additional
project expansion occurs by 2025. Using trip generation values to establish the impact of each
project on the transit system results in a SSC contribution in 2015 of 42 percent versus 58
percent for SUMC. The split is 31 percent for SSC and 69 percent for SUMC in 2025.
3.11 Transportation Demand Management Impacts
The proposed developments are currently served by the Marguerite shuttles that connect to the
Palo Alto and California Avenue Caltrain stations. Other transit service to the Caltrain stations
and the shopping center that provide connecting service to the Marguerites include SamTrans
Routes RX, 280, 281, 297, 390, 397, and KX; VTA Routes 22, 35, 89, and 522; the U Line from
the East Bay; and the Palo Alto shuttles. Development of the expanded shopping center and
hospital would increase demand for transit service in the area. Also, the TDM measures
proposed for the hospital (provision of GO Passes for all employees) will increase transit
ridership. The mode split to transit for the existing hospital is 8.9 percent according to Stanford
data. This includes ridership on Marguerite shuttles, SamTrans, AC Transit, and VTA buses,
and Caltrain. The mode split for transit is expected to increase to 21.1 percent if all hospital
employees are provided with GO Passes. The mode split to transit for the shopping center
would probably be no more than 1 or 2 percent. A total of 71 to 165 AM and 79 to 170 PM peak
transit trips would be created by the project, depending on the success of the GO Pass. Given
the high level of transit service to the surrounding area, increased transit ridership could be
accommodated by the existing routes, with three possible exceptions. Expansion of the Go
Pass program to all hospital employees will increase ridership on the Marguerite shuttles, most
notably Line A and Line B Counter-Clockwise. Increased ridership on these two routes could
cause a load factor of greater than 1.25. This would be considered a significant impact. This
impact is associated with the SUMC project and could occur by 2015 but may not occur until
post 2015. Historically, Stanford monitors ridership on the Marguerite and adjusts transit
service to meet demand. Monitoring of Lines A and B needs to continue with expansion of the
GO Pass program to all hospital employees. Also, the current load factor on the U Line from the
East Bay is approaching 1.0 (0.94 according to AC Transit). The expanded ridership could push
Stanford University Medical Center and Stanford Shopping Center
3.0 FUTURE CONDITIONS
3-116 January 13, 2009
the load factor above 1.0. A load factor on the U Line greater than 1.0 would be considered a
significant impact. This impact is also associated with the SUMC project and could occur by
2015 but may not occur until post 2015. It is also noted that Stanford would increase the
Marguerite shuttle services if the ridership increases and this could off-set the potential impact
to other transit services. Significant diversion of traffic to alternative modes is not as viable for
SSC as for SUMC. Therefore, the impacts to transit as a result of TDM is associated with
SUMC, rather than SSC.
3.12 Pedestrians and Bicycles Impacts
Pedestrian and bicycle traffic around the hospital and shopping center is currently very
extensive. Expansion of the two projects would increase the level of bicycle and pedestrian
activity. An extensive pedestrian and bicycle network currently exists around the shopping
center and hospital. This network should be enhanced in association with the two projects by
providing additional accesses to remove barriers. Figure 3-18 shows the Primary Pedestrian
and Bicycle Circulation as currently proposed. Pedestrian and bicycle facilities are provided on
nearly all streets in the network. There are also numerous off-road pedestrian-only as well as
combined pedestrian/bicycle facilities.
The study area is conducive to pedestrian and bicycle travel. Downtown Palo Alto, PAITS, the
Shopping Center, the Medical Center, and the University are all within a 20-minute walk if
linkages are made and barriers removed. The study area has barriers to pedestrian and bicycle
access to the shopping center and medical center. The Caltrain tracks and El Camino Real
separate the downtown from the shopping center; San Francisquito Creek separates the
residential neighborhoods of Menlo Park from the two projects; and Sand Hill Road separates
the residential areas to the northwest from the shopping center. The medical office buildings
and the Stanford Barn separate the residential areas from the medical center and the medical
center from the shopping center.
While both projects will continue to attract a high percentage of automobile traffic, alternative
modes of travel also need to be addressed. There is an opportunity to attract people from the
three residential neighborhoods that are within ½-mile walking distance to support pedestrian
activity within the projects’ study area. Residents of Sand Hill West and Menlo Park can benefit
from pedestrian access that links the medical center to the shopping center. Residents in
downtown Palo Alto have access to the study area via the Caltrain station access tunnels,
University Avenue undercrossing, and along Palo Alto Avenue to the intersection with Sand Hill
Road.
Additional connections would reduce walking and bicycle travel time between downtown and the
shopping center and medical center. The goal of the two projects would be to provide walking
and biking connectivity linking the shopping center, the medical center, the University, PAITS,
downtown and surrounding residential neighborhoods, providing an environment that
accommodates alternative modes of travel in addition to auto travel.
A comprehensive approach to providing needed pedestrian and bicycle improvements should
be incorporated into the project during the planning stages to avoid their preclusion in the future.
Impeding the development of pedestrian and bicycle improvements is a significant impact per

the City’s criteria. Both SSC and SUMC would be responsible to mitigate pedestrians and
bicycle impacts.
3.13 Emergency Vehicle Access Impacts
Emergency vehicles require access within the study area to respond to emergencies and also to
access the SUMC emergency room. Travel time by emergency vehicles would increase
because of additional traffic congestion associated with the projects. The City’s significance
criteria identify inadequate emergency access as a significant impact. The increased
Stanford University Medical Center and Stanford Shopping Center
3.0 FUTURE CONDITIONS

congestion identified in this analysis due to the SSC and SUMC projects at study area
intersections is considered a significant impact. Table 3-23 lists the intersections at LOS E or F
during the different analysis year for the different scenarios. The intersections listed in Table 3-
23 as operating at LOS E or F are either associated with SSC, SUMC or both and are also
separated by analysis year. The impact for each project and for each analysis for emergency
access is as defined in Table 2-23. Traffic operation at LOS E or F is considered a significant
impact to emergency access.
3.14 Construction Impacts
Project-related construction traffic could contribute to increased intersection delays and
interference with pedestrians, bicyclists, and transit. During the construction period, impacts
might arise from a substantial increase in heavy truck travel, as materials are brought in to the
project sites, and demolished or excavated materials are hauled out. Temporary lane or road
closures might be required for the construction and for underground utility work. Construction
activities would lead to both temporary disruption of transportation system operation and
possible damage to elements of the roadway system such as pavement and bridges. Figure 3-
19 illustrates the Stanford Area Truck Routes. All truck travel, either for excavation or for
transporting construction materials to the site would use these routes. From I-280 and the west,
Alpine Road, Junipero Serra Boulevard, Campus Drive West would be used to reach Welch
Road. From US 101 and the east, either San Antonio Road or Woodside Road would be used
to access El Camino Real. From there, trucks would follow Galvez Street to Arboretum Road,
and Sand Hill Road to Pasteur Drive. El Camino Real would be used for short construction-
related trips from the north and south. A detailed construction access plan shall be developed
for each project prior to the beginning of any construction activities. The construction access
plan shall be reviewed and approved by the City. Any deviation from that plan would be a
significant impact. Impact due to construction would be according to the construction activities
of each project.
