Stanford University Medical Center and Stanford Shopping Center1.0 INTRODUCTION

1-1 January 13, 2009

1.0 INTRODUCTIONTwo 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 MedicalCenter facilities and the other would expand Stanford Shopping Center. The operator ofStanford Shopping Center (Simon Property Group) has applied to the City of Palo Alto for theaddition of 240,000 square feet of new retail stores and restaurants, a new 120-room hotel and1,199 net new vehicular parking spaces. Stanford University Medical Center (SUMC) has alsosubmitted 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 potentialfuture traffic conditions associated with the proposed projects. The potential impacts areevaluated relative to the operation of public transportation, bicycle and pedestriantransportation, arterial roadways, intersections, freeways, and transportation demandmanagement (TDM) strategies.

1.1 Applicable Plans and PoliciesThe study area, shown in Figure 1-1, is part of the City of Palo Alto and the adjacent cities ofMenlo Park and East Palo Alto. Transportation planning in Palo Alto and the surrounding areais subject to the regulations of Federal, State, regional, and local agencies and programs.Federal regulations are administered by the Federal Highway Administration (FHWA) and theFederal Transit Administration (FTA). The California Department of Transportation (Caltrans) isresponsible for State roadways, and regional issues are addressed by the MetropolitanTransportation Commission (MTC). Congestion Management Agencies (CMAs) of both SantaClara County and San Mateo County have developed regulations and policies with relevance tothe proposed projects at the local level.

1.2 Federal AgenciesMTC, which is a regional San Francisco Bay Area agency, implements polices by the FHWAand the FTA. It oversees transportation improvements in the nine-county Bay Area. It is alsotasked with the development of the local State Transportation Improvement Program (STIP). Inaddition, the Transportation Equity Act for the 21st Century (TEA-21) empowers the MTC todetermine the mix of transportation projects best suited for the region’s needs.

1.3 State AgenciesCaltrans is the State agency responsible for State transportation facilities. It has jurisdictionover State highways in the study area, including El Camino Real (State Route 82), BayshoreFreeway (U.S. 101), Interstate 280, and the Dumbarton Bridge (State Route 84). Plans toprovide new access or alterations to existing access to a State Route require Caltrans approval.

Roadway improvements within a State right-of-way also need Caltrans approval, and theapproval process usually includes the development of detailed roadway geometrics and designplans.

1.4 Regional AgenciesMTC is the metropolitan planning agency in charge of transportation planning, coordinating andfinancing for the nine-county San Francisco Bay Area. MTC distributes Federal and State fundsto 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 intransportation analysis. The Peninsula Corridor Joint Powers Board (JPB) is the tri-countyagency (San Francisco, San Mateo, and Santa Clara counties) that has jurisdiction over theCaltrain rail service. The Dumbarton Bridge Bus Service (Line DB) is operated by AC Transitand funded by a consortium of several county transit districts, including the Santa Clara ValleyTransportation Authority (VTA), SamTrans and the Bay Area Rapid Transit District (BART).

The Bay Area Air Quality Management District (BAAQMD) provides both policy guidance andregulatory control over stationary and mobile air pollution sources. Under the California CleanAir Act (CCAA) of 1988, the BAAQMD is required to prepare a Clean Air Plan (CAP) to achieveState standards for ozone and CO. The 2007 Ozone Strategy, jointly prepared by the MTC andABAG, will show how the San Francisco Bay Area plans to comply with the State air qualitystandards for ozone and how the region will reduce transport of ozone and ozone precursors toneighboring air basins. Control measures will be established and adopted in the 2007-2009timeframe.

The CCAA states that strategies should emphasize reducing emission from transportation andother area-wide sources. The Act requires air districts to adopt, implement and enforceTransportation Control Measures (TCMs). The MTC develops, maintains and updates a list ofTCMs and distributes this information to keep the BAAQMD informed of trends.

1.5 Local AgenciesThe Congestion Management Agencies (CMA) of both Santa Clara County and San MateoCounty have regulations and policies that are relevant to the proposed project.

1.5.1 Santa Clara CountyThe Santa Clara Valley Transportation Authority (VTA) is the CMA for Santa ClaraCounty. It oversees the Congestion Management Program (CMP) that definesmethodologies and procedures for determining the transportation impact of a potentialproject. The most recent guidelines were updated in 2004. The following are CMPfacilities within the study area by functional classification.

Freeways: US 101 and I-280

Expressways and Arterials: Page Mill Road


1-4 January 13, 2009

Oregon Expressway El Camino Real

Intersections: El Camino Real/Sand Hill El Camino Real/Embarcadero/Galvez, El Camino Real/Page Mill/Oregon Expressway, El Camino Real/Palm Drive El Camino Real/University Avenue Junipero Serra Boulevard/Page Mill

VTA has jurisdiction over public transit in the County. VTA bus service includes severallocal 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 Countyroadways and airports, including the Palo Alto Airport, Page Mill Roadway, FoothillExpressway, Oregon Expressway, Stanford Avenue, and Junipero Serra Boulevard.

1.5.2 San Mateo City/County Association of GovernmentsThe San Mateo City/County Association of Governments has been designated as theCMA for San Mateo County. Within the study area, the San Mateo County CMP networkincludes US 101, I-280, SR 84, and El Camino Real. The intersections within the studyarea included under the CMP network are:

Marsh Road and Bay Road Willow Road and Bayfront Expressway Bayfront Expressway and University Avenue

Public transit service in San Mateo County is provided by SamTrans. SamTrans makesconnections to public transit services in Santa Clara County in Palo Alto.

1.6 Existing Regional and Local NetworkThe system of major roadways surrounding Stanford is part of the regional system servingStanford, its neighboring communities on the Peninsula and across the Bay. All roadways areclassified according to their primary functions, as described below.

Freeway. A major roadway with controlled access, devoted exclusively to trafficmovement, mainly of a through or regional nature.Expressway. A major roadway with less controlled access than a freeway, linkingfreeways with arterials, and providing access to major destinations.Arterial. A major roadway mainly taking traffic to and from expressways andfreeways and providing access to major destinations and also adjacent properties.

Collector. A roadway that collects and distributes local traffic to and from arterials,and provides access primarily to adjacent properties.


1-5 January 13, 2009

Regional Roadway Facilities -- Regional access to the area is provided by US 101 andInterstate 280 that run the length of the San Francisco Peninsula from San Francisco to SanJose and by the Dumbarton Bridge that provides access to / from the East Bay. Descriptions ofthese routes are provided below.

US 101 (Bayshore Freeway) is an eight-lane facility in the project area under thejurisdiction of the Caltrans. It has interchanges at Marsh Road, Willow Road,University Avenue and Embarcadero Road/Oregon Expressway within the studyarea. US 101 is classified as a freeway.Interstate 280 (Junipero Serra Freeway) is an eight-lane facility in the project areaunder the jurisdiction of Caltrans. In the study area, I-280 has interchanges servingPalo Alto at Sand Hill Road, Alpine Road, and Page Mill Road / Arastradero Road.Interstate 280 is classified as a freeway.State Route 84 (Dumbarton Bridge) is a six-lane facility under the jurisdiction ofCaltrans. This facility connects Alameda County to San Mateo and Santa ClaraCounties. It is classified as a freeway from I-880 to University Avenue in East PaloAlto.

Local Access -- The primary streets that provide access within the study area are discussedbelow. These streets provide access to the study area as well as the local roadway network.For the purpose of this traffic and circulation discussion, roadways that parallel US 101 and I-280 are considered to run in the north/south direction and roadways that generally traversetoward the Santa Cruz Mountains or San Francisco Bay are considered to run in the east/westdirection.

El Camino Real (State Route 82) is an arterial that runs north-south from SanFrancisco to San Jose, parallel and between US 101 and I-280. El Camino Real is asix-lane road way south of Ravenswood Avenue in Menlo Park and a four-lanedivided road way north of Ravenswood Avenue to the Atherton border. The majorintersections along El Camino Real within the study area are controlled by trafficsignals with the exception of the El Camino Real/Palm/University Avenueinterchange. This interchange is grade-separated and diamond-configured. The on /off ramps to El Camino Real are controlled by traffic signals. In the City of PaloAlto’s Comprehensive Plan, El Camino Real is classified as an arterial. It isconsidered a primary arterial in the City of Menlo Park.Middlefield Road is a two- to four-lane undivided road that runs north-south, parallelto and between US 101 and El Camino Real. Middlefield Road runs from RedwoodCity to the City of Mountain View. The major intersections along Middlefield Roadare signalized. Middlefield Road within Palo Alto is classified as an arterial. Underthe City of Menlo Park guidelines, it is considered as a minor arterial.Alma Street is primarily a four-lane arterial that runs north-south, parallel to theCaltrain railroad tracks. Alma Street runs from El Camino Real (near SanFrancisquito Creek) to the San Antonio Road interchange in Mountain View, where itbecomes Central Expressway (Santa Clara County G6) and terminates at De LaCruz Boulevard in the City of Santa Clara. In the study area, Alma Street has limited


1-6 January 13, 2009

access from the west side due to the immediate proximity of the Caltrain railroadtracks. Alma Street is classified as an arterial.Sand Hill Road is a two- to four-lane arterial that runs east-west from Portola Roadin the Town of Woodside to the Stanford Shopping Center in the City of Palo Alto. Itis a two lane road from Portola Road to the I-280 interchange and widens to fourlanes between I-280 and Arboretum Road. It narrows to a two lane road betweenArboretum Road and El Camino Real. Within the study area, Sand Hill Roadprovides connections to the Cities of Menlo Park and Palo Alto, as well as access toStanford University. Sand Hill Road within Palo Alto is classified as an arterial. It isconsidered a primary arterial under the City of Menlo Park Guidelines.Arboretum Road is primarily a two-lane road located within the Stanford Universitycampus.

Within the main body of thistransportation study, intersections are analyzed according to the City of Palo Alto’s criteriaregardless of the intersection’s location. Roadway segments in Menlo Park are analyzedaccording to Menlo Park’s criteria. In Appendix A of this report, the Menlo Park intersectionsare also analyzed according to Menlo Park’s criteria for informational purposes since the criteriaare different from those of City of Palo Alto.

1.8.1 City of Palo AltoTraffic impact would be considered significant when the project results in the following:

Cause a local (City of Palo Alto) intersection to deteriorate below Level ofService (LOS) D; or

Cause a local intersection already operating at LOS E or F to deteriorate inthe 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

Cause a regional intersection to deteriorate from LOS E or better to LOS F; or Cause a regional intersection already operating at LOS F to deteriorate in the

average control delay for the critical movements to increase by four secondsor more, and the critical v/c to increase by 0.01 or more; or

Queuing impacts include, but arenot limited to, spillback queues at project access locations, queues at turnlanes at intersections that block through traffic, queues at lane drops, queuesat one intersection that extend back to impact other intersections andspillback queues on ramps; or

Cause a freeway segment (for each direction of traffic) to operate at LOS F orcontribute traffic in excess of 1 percent of segment capacity to a freewaysegment already operating at LOS F; or

Impede the development or function of planned pedestrian or bicyclefacilities; or

Impede the operation of a transit system as a result of congestion; or Result in inadequate on-site parking supply; or Create an operational safety hazard; or Result in inadequate emergency access; or 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 collectorresidential street.

2.0 EXISTING CONDITIONSThis section of the report presents the existing conditions for the different aspects oftransportation issues within the study area. It covers intersections and roadway analysis as wellas public transit, bicycle and pedestrian facilities and transportation demand managementprograms relevant to the proposed projects.

2.1 Intersection and Roadway AnalysisA total of 60 signalized intersections and 3 unsignalized intersections were identified for analysisin this study. Existing turning movement volumes during peak hours were obtained andanalyzed using TRAFFIX 7.9. 24-hour counts for eight roadway segments were conducted forseven days to determine their ADT. In addition, volumes for six freeway segments wereobtained.

2.1.1 Intersection Analysis MethodologyThe current procedures adopted for intersection operational analysis in Santa ClaraCounty are according to the Highway Capacity Manual (HCM) 2000. HCM 2000 isapplied via the TRAFFIX 7.9 software package per the requirements of the CMA. Levelof service for signalized intersections is defined in terms of control delay. The definitionsof level of service A through F are noted in Table 2-1. Control delay includes initialdeceleration delay, queue move-up time, stopped delay and final acceleration delay.Average control delay weights the delay per movement according to the traffic volumesfor that movement. The critical volume to capacity (v/c) ratio is an approximate indicatorof the overall sufficiency of an intersection. The critical v/c ratio depends on theconflicting critical lane flow rates and the signal phasing. V/C ranges from 1.0 when theflow rate equals capacity to 0.0 when the flow rate is zero. Values above 1.0 indicate anexcess 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 byTRAFFIX software, is used for unsignalized intersection LOS calculations. Table 2-2lists the thresholds for the LOS for unsignalized intersections.

LOS rating is based on the weighted average control delay expressed in seconds pervehicle for all approaches. At two-way or side-street controlled intersections, LOS iscalculated for each controlled movement, not for the intersection as a whole. For singleapproaches, the control delay is computed as the average of all movements in that lane.The threshold values for unsignalized intersections are different than the thresholdvalues for signalized intersections due to different driver expectations of level ofperformance. Higher delay for the same LOS is acceptable at a signalized intersectionas 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 areoutlined in HCM 2000 but LOS D/E and E/F density thresholds are modified to reflectSanta Clara County conditions. The LOS thresholds for freeway segments arepresented in Table 2-3.

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

2.1.3 Analysis ResultsTable 2-4 presents the TRAFFIX results for the 63 intersections under the existingcondition. Intersections that currently operate at LOS E or F are shaded in Table 2-4.

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 SerraBoulevard-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 acceptablelevels of service for the PM peak hour.

The ADT (total of both directions) for residential roads identified in the study is shown inTable 2-5. Table 2-5 also notes the existing TIRE index. The TIRE index is a numericalrepresentation of a resident’s perception of the influence of traffic on daily life. Streetswith TIRE levels above 3.0 are considered traffic-dominated, while those with indexesbelow 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.

On weekends, the earliest hourly northbound train leaves Palo Alto at7:31am (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 PaloAlto at 1:03am (Saturday). Caltrain provides Baby Bullet Express Service that allowsunder 1-hour travel between San Jose and San Francisco. This service runs during boththe 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 servicethroughout the day between San Jose and San Francisco.

2.3 Bicycles and PedestriansBicycle 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 firstcommunities in California to establish a dedicated bicycle system. Since then, Menlo Park, PaloAlto and Stanford University have made progress in developing a system of bicycle andpedestrian 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 pedestriansseparate 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 orsemi-exclusive use of bicycles with through travel by motor vehicles or pedestriansprohibited, but with vehicle parking and cross flows by pedestrians and motoristspermitted.Class III (bike route) provides bicyclists with facility designated by signs orpermanent 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 arearespectively. There are portions of the Stanford University campus that are bike/pedestrianaccess only, which are also identified.

Signalized crossings of El Camino Real, which have pedestrian signals to provide safepedestrian/bicycle crossings, are provided at numerous locations in the study area includingSand Hill Road, Quarry Road, University Avenue, and Embarcadero Road. Bicycles are legalon all streets in Palo Alto, except freeways, though there are some major streets with narrowlanes 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 include14 underpasses or bridges. Palo Alto was the first community to develop the concept of abicycle boulevard, which is a low-volume through street where bicycles have priority over

automobiles. Conflicts between bicycles and automobiles are minimized, and bicycle travel timeis reduced by removing stop signs and other impediments to bicycle travel. The bicycleboulevard is located on Bryant Street. In order to ensure areas of roadways used by bicyclistsare maintained at or above those used by motorists, the City is adjusting its street evaluationcriteria 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 bicyclesdiscussed above. With some exceptions, the regional connections described for bicyclists alsoexist for pedestrians. All Class I bicycle paths and bridges are available to and used bypedestrians. Sidewalks are present in most parts of Palo Alto although there are some gaps;Stanford University provides a comprehensive pedestrian/bicycle circulation system thatcontributes to the ease of moving to, from, and throughout the campus without the need for anautomobile. There are several policies that the University implements to discourage the use ofvehicles 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 facilitatepedestrian and bicycle use;

Maintain/improve the pedestrian and bicycle circulation system that connect placesof living and work; and

Provide a safe and easily understood system of pedestrian pathways and bikeways.

2.4 ParkingOff-street parking is currently provided for both the Stanford Medical Center and the StanfordShopping Center. A total of 5,801 parking spaces are currently provided at the StanfordShopping Center for 1,412,368 square feet of commercial area. This is in excess of the city’sparking code that that requires a minimum of one parking space per 275 square feet of retailspace at a shopping center.

Based on the recent parking survey (Fehr & Peers, September 2007), SUMC (including both thehospitals and medical offices) currently has about 8,900 parking spaces available includingabout 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 thesespaces 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 wereoccupied during both periods; of which about 4,200 (65 percent) belong to hospital employeesand visitors. The survey also noted that the mid-morning period has a higher parking demandcompared to the mid-afternoon period. The demand at the dedicated medical office parkingarea 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-alonevehicle trips. Although a state law was passed in 1995 that prohibited agencies and cities fromrequiring mandatory TDM, the City of Palo Alto and Stanford University still voluntarily provideTDM programs for their employees. Key components of the current TDM program administeredby Stanford are summarized below.

2.5.1 Stanford University Medical CenterSUMC’s TDM program for students, staff, and faculty consists of several elements. Theprogram is designed to reduce ‘drive-alone’ by encouraging the use of transit, walking andcycling in order to help meet the “no net new commute trips” goal. This is required by the 1989and 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.: Clean Air Cash or Carpool Credit Reserved parking spaces for all carpools/vanpools Vanpool subsidies Members-only commuter gifts

Marguerite: Free, comprehensive campus shuttle system, open to the publicthat connects with local transit and Caltrain. New buses run onbiodiesel fuel and real-time schedules can be viewed on theweb under the Automated Transportation Management System.

VTA Eco-Pass Available free to eligible hospital and university employees,allows unlimited travel on VTA buses (including expressservices), VTA light rail, Dumbarton Express, Highway 17Express and Monterey-San Jose Express

Line U StanfordExpress:

Free use of East Bay express bus that connects BART, ACEtrain and remote park and ride lots (e.g. Ardenwood Farms) toStanford.

Bicycle Program Programs that promote and encourage the safe use of bicyclesin and around the campus e.g. bike light giveaways, safetyeducation programs, bike safety road show, commute planning/ cycling information, etc.

Vehicle Rental: Hourly, half-day and full-day car rental (through on-campusEnterprise Rent-a-Car office) available to faculty, staff andstudents 18 years and older.

Charter BusServices:

Group transportation services are provided during events likeconferences or student activities to allow for alternative forms ofcommuting.

Parking Program: Programs to manage parking and discourage driving to and incampus e.g. no freshman cars, parking permit fees, short-termparking options etc.

Others: Flexible work options (staggered work hours, compressed workweek etc.), alternative transportation promotional events, one-on-one commute planning assistance, etc.

Stanford University Medical Center and Stanford Shopping Center3.0 FUTURE CONDITIONS

3-1 January 13, 2009

3.0 FUTURE CONDITIONSThis section of the TIA provides an evaluation of potential transportation impacts in the PaloAlto, Menlo Park and East Palo Alto areas associated with the proposed expansion of StanfordShopping Center (SSC) and Stanford University Medical Center (SUMC). The impacts areevaluated relative to the operation of intersections, arterial roadways, freeways, bicycle andpedestrian transportation, public transportation and transportation demand management (TDM)strategies. Mitigation measures are recommended which, if implemented, would reduceimpacts 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:

By 2015, SSC and the medical office buildings (MOB) of SUMC at the Hoover Pavilionsite would be fully built-out while the hospital and clinic / medical office portion of themain SUMC site would be occupied and operated at equivalent to approximately 60percent build-out. The increase in employees and patients would be 60% of the fullSUMC project build-out.

By 2025, both SSC and the all of SUMC would be at their full build-out and occupancycondition.

Project analysis would focus on these two stages of development as well as analysis of thestudy intersections, roadway and transportation facilities if only one of these projects isconstructed.

3.1 Project AnalysisTwo horizon years, 2015 and 2025, are being used for the future conditions analysis. Thebaseline traffic volumes were obtained from the recently updated City of Palo Alto traveldemand forecasting model. This model was developed based on Santa Clara County regionalVTA forecasting model, with ABAG projections of housing and employment data. This model isconsistent with the CMA and MTC models. In 2015, the traffic projections from the traveldemand model result in six intersections operating at LOS E and an additional sevenintersections operating at LOS F without the addition of traffic from either projects. In 2025, thetraffic projections from the travel demand model result in three intersections operating at LOS Eand 12 intersections operating at LOS F in the AM peak hour and five intersections operating atLOS E and 18 intersections operating at LOS F in the PM peak hour without traffic from eitherprojects. Traffic congestion prior to the addition of project traffic tends to magnify the projectimpacts. For this report, the City of Palo Alto and Santa Clara County CMPguidelines/significance criteria are used for determining project impacts on all studyintersections; regardless of which agency operates the intersections (City of Palo Alto or otheradjoining jurisdictions). Project impacts are determined by comparing the ‘no project’ scenarioduring the different horizon years with the ‘with project’ scenarios. Project impacts for studyintersections within the City of Menlo Park are also determined by using the City of Menlo Parkguidelines and are presented in Appendix A for reference. A total of 63 intersections areanalyzed 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 the2025 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 percentbuild-out compared with No Build 2015 traffic volumes

2. Impact of SUMC only in 2015 – No Build 2015 traffic volumes + SUMC at 60 percentgrowth compared with No Build 2015 traffic volumes

3. Impact of SSC + SUMC in 2015 – No Build 2015 traffic volumes + SSC at 100percent build-out + SUMC at 60 percent growth compared with No Build 2015 trafficvolumes

4. Impact of SUMC only in 2025 - No Build 2025 traffic volumes + SUMC at 100percent build-out compared with No Build 2025 traffic volumes

5. Cumulative Impact of SUMC in 2025 - No Build 2025 traffic volumes + SUMC at 100percent + 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 100percent + 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 + SUMCat 100 percent + SSC at 100 percent build-out compared with No Build 2025 trafficvolumes

3.2 Without ProjectTraffic volumes from the Palo Alto Citywide forecasting model are used as the futurebackground volumes. The geometry of the 63 study intersections are presented in Figures 3-1athrough 3-1d and 3-2a through 3-2d for 2015 and 2025 respectively. The intersection numberswere previously noted in Figure 1-1. The Durand Way extension to Welch Road is reflected inFigure 3-2 only, as it would not be completed by 2015. With the exception of Durand / Sand HillRoad (#57) and Durand / Welch (#60), all other intersection geometrics are assumed to remainconsistent between 2015 and 2025. Figures 3-3a through 3-3d and 3-4a through 3-4d show thetraffic 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 16intersections were expected to perform at LOS E or F in 2015 and a total of 25 suchintersections in 2025 without the addition of any traffic from the SUMC or SSC projects. Theseintersections are highlighted as well.During the AM peak hour in 2015, no intersections would operate at LOS E. However, thefollowing 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)Middlefield Road / Ravenswood Avenue (#46) (Menlo Park)

3.3 Project Trip GenerationIn order to determine project impacts, the number of trips generated by each project needs to becalculated. The following sections presents the trip generation for the two projects. Thediscussion will focus on the SSC and the SUMC separately.

3.3.1 SSCThe 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. Thisexpansion is expected to be fully completed by 2015.


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. Regressionequations are used to estimate project traffic volumes. Appendix B lists the regressionequations and trip rates used. Regression equations indicate that shopping centers generatetraffic at a decreasing rate as the facility size expands. Newly generated project traffic is the netdifference between the projected trips for the new total area and the projected trips for theexisting area. For this study, high-turnover restaurants are included in the shopping center areafor the trip generation rate calculations whereas high-quality restaurants and the hotel arecalculated separately. The assumption is that traffic to a high-quality restaurant is independentof 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-turnoverrestaurant.

Adjustments were made to the trips generated to account for pass-by and diverted trips to theshopping center during the PM peak hour. Pass-by trips are made as intermediate stops on theway from an origin to a primary destination without a route diversion. They are trips attracted tothe shopping center from traffic already passing the project site on an adjacent street with directaccess to the project site. Based on the pass-by trip regression equation from the TripGeneration Handbook (ITE, 2001), it is estimated that about 10 percent of the expected tripsgenerated 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 (theshopping center) but that require a diversion from that roadway to another to gain access to the


3-29 January 13, 2009

site. Diverted trips consist of traffic that is already on the roadway network. Therefore, it wasremoved from trip generation. However, since it travels through intersections adjacent to theproject area, it was assigned to intersections surrounding the project. The revised tripsgenerated 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 SUMCThe 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 theproposed expansion, several existing MOB (119,900 square feet) would be demolished. Thiswould be taken into account when calculating the trips generated by the project. HooverPavilion 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 theproposed expansion area for the hospitals to better reflect the facilities practical use. Thehospitals are currently undersized relative to the services they provide. Part of the proposedexpansion is needed to better accommodate the existing uses which would have no impact onthe trips generation. This is ‘right-sizing’ adjustment. Net proposed expansion for StanfordHospital 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 thetraffic volumes and the size of existing buildings. The hospitals would be operating 60 percentof the full build-out in 2015 and the trips generated are presented in Table 3-5. Trips generatedfor a full build-out (100 percent) of the SUMC in 2025 are shown in Table 3-6. Appendix C andD contains details of the review and validation of the hospital trip generation statistics.

white paper analysis contained in Appendix C

After determining the number of trips generated by the project, they are distributed andassigned to all study intersections. Distribution is divided into regional and local patterns to


3-31 January 13, 2009

more accurately reflect the origins of the trips. Appendix E presents the details of this tripdistribution. SUMC trips are divided into 75 percent regional and 25 percent local. Thesepercentages were derived from existing employee zip code data. A majority of peak hour trafficis associated with employee travel. However, some hospital related peak hour travel will bemade by patients or visitors. The travel pattern of patients and visitors is expected to be similarto that of employees during the peak hour analysis periods. SSC trips are divided into 30percent regional and 70 percent local; determined from the Palo Alto Citywide travel demandforecasting model. Figures 3-5 and 3-6 show the percentage distribution for SUMC and Figures3-7 and 3-8 show the percentage distribution for SSC. The project trips were then assigned toeach 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 differentproject scenarios.

3.4 Project ImpactsProject 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 areevaluated based of City of Palo Alto criteria. Project impacts on freeway segments andresidential roadways are also discussed. In particular, project impacts on several roadways inMenlo Park are evaluated based on ADT according to the City of Menlo Park significancecriteria. The significance criteria were previously presented in Section 1.8.

3.4.1 Impact of SSC only in 2015No Build 2015 traffic volumes + SSC at 100 percent build-out compared with No Build2015 traffic volumes

The traffic volumes for this scenario are shown in Figures 3-13a through 3-13d. Theresults 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, duringthe AM peak, no intersections would be adversely impacted by the project. This scenariois expected to have the least impact as it generates the smallest number of trips. As aretail center, it is not expected to generate many trips early in the day. Most retailemployees would not start work until after the highway peak and shoppers would notarrive during the AM peak hour. Six intersections would be adversely impacted by theproposed SSC expansion in the PM peak:

El Camino Real / University Avenue (#10) – Palm Drive – LOS changes from D toE and is considered adversely impacted.

Middlefield Road / Lytton Avenue (#19) - LOS remains at F but the averagecritical delay increased by 4 seconds and the V/C increased by 0.012. Thisintersection is significantly affected by the project.

Junipero Serra Boulevard / Campus Drive West (#26) – LOS remains at E but theaverage critical delay increased by 18.8 seconds and the V/C increased by0.046. This intersection is significantly affected by the project.

Junipero Serra Boulevard / Alpine-Santa Cruz Avenue (#27) - LOS changes fromD to E and is considered adversely impacted.

Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of PaloAlto has not adopted specific criteria for impacts at unsignalized intersections.Therefore if traffic signal warrants are met, additional traffic through theintersection would constitute a significant impact. Traffic signal warrants at thisintersection are met at baseline conditions as well as with project.

Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F but theaverage 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 2015No Build 2015 traffic volumes + SUMC at 60 percent of full build-out occupancycompared with No Build 2015 traffic volumes

The traffic volumes for this scenario are shown in Figures 3-14a through 3-14d. Theresults of the analysis are included in Table 3-8. For this scenario, SUMC is at 60percent occupancy of the full build-out. As seen in Table 3-8, four intersections wouldbe adversely impacted by the proposed SUMC project during the AM peak:

El Camino Real / Galvez (#11) - LOS changes from D to E with the projectand is considered significantly impacted.

El Camino Real / Page Mill-Oregon Expressway (#16) - LOS remains at Fwith or without the proposed project. The average critical delay increased by6.1 seconds and the V/C increased by 0.016. This intersection is significantlyaffected by the project.

Alpine / I-280 NB Off-Ramp (#62) (unsignalized) - LOS remains at F. TheCity of Palo Alto has not adopted specific criteria for impacts at unsignalizedintersections. Therefore if traffic signal warrants are met, additional trafficthrough the intersection would constitute a significant impact. Traffic signalwarrants are met at this intersection.

Alpine / I-280 SB Off-Ramp (#63) (unsignalized)- LOS remains at F. The Cityof Palo Alto has not adopted specific criteria for impacts at unsignalizedintersections. Therefore if traffic signal warrants are met, additional traffic

through the intersection would constitute a significant impact. Traffic signalwarrants are met at this intersection.

During the PM peak hour, eight intersections would be adversely affected. The eightaffected intersections are:

El Camino Real / University Avenue (#10) - LOS changes from D to E withthe project and is considered significantly impacted.

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 by0.01. This intersection is significantly affected by the project.

Middlefield Road / Willow Road (#18) - LOS changes from E to F with theproject. The average critical delay increased by 8.7 seconds and the V/Cincreased by 0.027. This intersection is significantly affected by the project.

Middlefield Road / Lytton Avenue (#19) - LOS remains at F. The averagecritical delay increased by 5.2 seconds and the V/C increased by 0.013. Thisintersection is significantly affected by the project.

Junipero Serra Boulevard / Page Mill Road (#23) - LOS remains at F. Theaverage critical delay increased by 4.3 seconds and the V/C increased by0.01. This intersection is significantly affected by the project.

Junipero Serra Boulevard / Alpine / Santa Cruz (#27) - LOS changes from Dto E with the project and is considered significantly impacted.

Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City ofPalo Alto has not adopted specific criteria for impacts at unsignalizedintersections. Therefore if traffic signal warrants are met, additional trafficthrough the intersection would constitute a significant impact. Traffic signalwarrants are met at this intersection.

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 atunsignalized 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 aswell as with project.

3.4.3 Impact of SSC + SUMC in 2015No Build 2015 traffic volumes + SSC at 100 percent build-out + SUMC at 60 percentoccupancy 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. Theresults of the analysis are included in Table 3-9.

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:

El Camino Real / Galvez (#11) – LOS changes from D to E and is thereforeconsidered significantly impacted by the projects.

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 by0.02. This intersection is significantly affected by the project.

Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F. Theaverage critical delay increased by 4.7 seconds and the V/C increased by0.015. This intersection is significantly affected by the projects.



In the PM peak hour, a total of 11 intersections would be significantly impacted by theproposed project:

El Camino Real / Valparaiso (#1) Avenue - LOS changes from D to E and istherefore considered significantly impacted by the projects.

El Camino Real / University Avenue (#10) - LOS changes from D to E and istherefore considered significantly impacted by the projects.

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 by0.016. This intersection is significantly affected by the projects.

Middlefield Road / Willow Road (#18) - LOS changes from E to F with theproject. The average critical delay increased by 11.6 seconds and the V/Cincreased by 0.036. This intersection is significantly affected by the projects.

Middlefield Road / Lytton Avenue (#19) - LOS remains at F. The averagecritical delay increased by 9 seconds and the V/C increased by 0.024. Thisintersection is significantly affected by the projects.


3-73 January 13, 2009

Junipero Serra Boulevard / Page Mill Road (#23) - LOS remains at F. Theaverage critical delay increased by 7.3 seconds and the V/C increased by0.016. This intersection is significantly affected by the projects.

Junipero Serra Boulevard / Campus Drive West (#26). - LOS remains at E.The average critical delay increased by 21.6 seconds and the V/C increasedby 0.053. This intersection is significantly affected by the projects.

Junipero Serra Boulevard / Alpine-Santa Cruz Avenue (#27) - LOS changesfrom D to E and is therefore considered significantly impacted by the projects.

Arboretum / Galvez (#37) (unsignalized) - LOS remains at F. The City of PaloAlto has not adopted specific criteria for impacts at unsignalized intersections.Therefore if traffic signal warrants are met, additional traffic through theintersection would constitute a significant impact. Traffic signal warrants aremet at this intersection.

Middlefield Road / Ravenswood Avenue (#46) - LOS remains at F. Theaverage critical delay increased by 10.9 seconds and the V/C increased by0.026. This intersection is significantly affected by the projects.


3.4.4 Impact of SUMC only in 2025No Build 2025 traffic volumes + SUMC at 100 percent build-out compared with No Build2025 traffic volumes

The traffic volumes for the scenario are shown in Figures 3-16a through 3-16d. Theresults 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/fromSUMC would increase. A total of 16 intersections would be negatively impacted by theproposed expansion during the AM peak hour as presented in Table 3-10:

El Camino Real / Valparaiso Avenue (#1) - LOS remains at E. The averagecritical delay increased by 8.2 seconds and the V/C increased by 0.023. Thisintersection is significantly affected by the project.

El Camino Real / Ravenswood Avenue (#3) - LOS remains at F. Theaverage critical delay increased by 14 seconds and the V/C increased by0.034. This intersection is significantly affected by the project.

El Camino Real / University Avenue (#10) - LOS changes from D to E and istherefore considered significantly impacted by the project.

3.4.5 Cumulative Impact of SUMC in 2025No Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-outcompared with No Build 2025 traffic volumes + SSC at 100 percent (Base A)



3-83 January 13, 2009

The traffic volumes for this scenario are shown in Figures 3-17a through 3-17d. Theresults of the analysis are included in Table 3-11. As noted on Table 3-11, a new basefor comparison, Base A, is used. Base A represents the 2025 No Build volumes plus thefull development of SSC.

In this scenario, it is assumed that the SSC has been completed in 2015 and isconsidered part of the background traffic in 2025. The SUMC project volumes areadded 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 inTable 3-11:

El Camino Real / Valparaiso (#1) - LOS remains at E. The average criticaldelay increased by 8.5 seconds and the V/C increased by 0.023. Thisintersection is considered significantly affected by the projects.

3.4.6 Cumulative Impact of SSC in 2025No Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-outcompared 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 throughFigure 3-17d. The analysis results are shown in Table 3-12. As noted on Table 3-12, anew base for comparison, Base B, is used. Base B represents the 2025 No Buildvolumes plus full development of SUMC.

Only one intersection is adversely impacted by the project under this cumulativescenario comparison in the AM peak:

Santa Cruz / Sand Hill (#30) - LOS remains at LOS F but the critical averagedelay increased by 4.6 seconds and V/C increased by 0.011. This isconsidered significantly impacted by the projects.

There are eleven intersections that would be adversely impacted by the project duringthe PM peak.

El Camino Real / Valparaiso (#1) - LOS remains at F but the average criticaldelay increased by 6.2 seconds and the V/C increased by 0.014. Thisintersection is considered significantly affected by the projects.

El Camino Real / Middle Road (#5) - LOS changes from D to E and istherefore considered significantly affected by the projects.

3.4.7 2025 with SSC and SUMC – Cumulative of SSC + SUMCNo Build 2025 traffic volumes + SUMC at 100 percent + SSC at 100 percent build-outcompared with No Build 2025 traffic volumes

This is the worst-case scenario as both SSC and SUMC are at full build-out. Whilelesser trips would be generated for the SSC during the AM peak hour due to the landuse, the PM peak hour results in this scenario having the highest number of tripsgenerated. 16 and 21 intersections would be adversely affected during the AM and PMpeak hour respectively. The traffic volumes for this scenario were previously shown inFigures 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:

El Camino Real / Valparaiso Avenue (#1) - LOS remains at E but the averagecritical delay increased by 9.2 seconds and the V/C increased by 0.025. Thisintersection is considered significantly affected by the projects.

El Camino Real / Ravenswood Avenue (#3) - LOS remains at F but theaverage critical delay increased by 15.7 seconds and the V/C increased by0.038. This intersection is considered significantly affected by the projects.

El Camino Real / University Avenue (#10) - LOS changes from LOS D to LOSE and is therefore considered significantly impacted.

El Camino Real / Embarcadero-Galvez (#11) - LOS remains at F but theaverage critical delay increased by 11.1 seconds and the V/C increased by0.028. This intersection is considered significantly affected by the projects.

3.5 Project Impact Analysis SummaryA summary of project impacts for all the project scenarios is presented in Table 3-14. For thedifferent ‘bases’ used for comparison, intersections performing at LOS E or F are highlighted in‘diamond’. Intersections exceeding the criteria thresholds and considered as adversely affectedby the project are highlighted by the different shapes. Squares are for the SSC, dots are for theSUMC and triangles are for the combined effect of SSC and SUMC. Appendix F shows theTraffix 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 andSUMC would only be equivalent to 60 percent build-out. In addition, impacts during the AMpeak are less than during the PM peak. Less employees and shoppers at the SSC would becommuting during the AM peak whereas a larger number of SSC shoppers would be travelingduring the PM peak hour. This can be seen clearly from column B of Table 3-14 where nointersections would be negatively impacted in 2015 during the AM peak. Six intersections wouldbe impacted during the PM peak due to the SSC project, of which three are in the City of PaloAlto. Given that part of the study area is in the City of Menlo Park and some intersections areunder the jurisdiction of the County, the summary table presents the total number ofintersections that would be adversely impacted by the project and also notes the number ofintersections impacted in Palo Alto. A similar trend is seen for the SUMC. Four Palo Altointersections would be impacted during the AM peak hour in 2015 and five out of eight impactedintersections are in Palo Alto. Under the effect of both the SSC and SUMC, five intersectionswould be adversely affected in the AM peak hour by the project, with four of these intersectionsbeing in Palo Alto. During the PM peak hour, 11 intersections would be affected of which sevenare in Palo Alto.

In 2025, there are different comparison scenarios dependent upon the completed parts of theproject in 2015. If SSC has been built in 2015, its generated trips would be part of thebackground traffic (New Base A). The effect of SUMC in both the AM and PM peak hours arepresented in Columns M and T respectively. A total of 16 intersections would be affected in theAM peak hour and 20 in the PM peak hour. The number of affected intersections in Palo Alto iseight and ten respectively. On the other hand, if the SSC did not get built in 2015, the effect ofSUMC alone is presented in Columns J and Q for the AM and PM peak hours respectively. Ofthe 16 impacted intersections in the AM peak hour, eight are in Palo Alto. Of the 18 impactedintersections in the PM peak hour, nine are in Palo Alto. In order to determine the effect of theSSC project in 2025, comparison is made with the scenario where SUMC is part of thebackground as presented in Columns O and V. Similar to the trend in 2015, impact during theAM peak hour is minimal with only one intersection in Menlo Park being affected. During theevening peak, eleven intersections would be affected with three in Palo Alto.

3.6 Freeway AnalysisBased on the CMP requirements for freeways, Table 3-15 presents the number of project tripson the different freeway segments within the study area. The number of project trips addedonto the freeway would determine if a freeway analysis is required. If the added project trips aremore than one percent of the freeway capacity for a freeway section currently operating at LOSF, 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 segmentscovered. HOV lanes have been included in this calculation. There is one HOV lane on bothnorthbound and southbound of US 101 but none along the segments of I-280 within the studyarea. 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 beingadded. It can be seen from the Table 3-15 that the number of project trips expected on theregular freeway lanes would be less than one percent for all study segments. As such, nofurther analysis is necessary. It is therefore inductive that the individual SSC and SUMC projectwould 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. Astreet is considered impacted if the TIRE Index increases by 0.1. The various project scenariosare compared to the base to determine any project impact. No residential roadway segmentswould 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 wouldsignificantly affect the section of Hamilton Avenue between Chaucer Street and Lincoln Avenueas 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 wouldconstitute a change of 0.1 in the TIRE Index. The cumulative ADT volume of the SSC and theSUMC projects is 515 which would be considered a significant impact as the TIRE Index wouldchange. However, the TIRE index is based in ADT not peak hour traffic. While peak hour trafficmay be diverted to Hamilton Avenue, the same proportion of non-peak hour traffic wouldprobably not be diverted. Therefore, the ADT values may be overstated. The other residentialroad segments would not be adversely by the project in 2025 as the increase in ADT volumedoes not bring about any change in the TIRE Index. Table 3-17 also represents the 2025cumulative condition. Mitigation of impacts to residential streets requires a reduction in trafficvolume. The impact to Hamilton Avenue is caused by the cumulative effect of both projects in2025. SUMC constitutes 92 percent of the traffic and SSC contributes 8 percent. The effect ofeach project individually is comparable to these percentages.

3.7.1 Menlo Park Roadway AnalysisAs part of the City of Menlo Park evaluation criteria, selected roadways are beingevaluated to determine the effect of the proposed projects. Average daily traffic (ADT) ofthese roadways were calculated for the different scenarios and compared to the ‘noproject’ 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 usethis evaluation methodology. The TIRE index for most of these roadway segmentswould 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 SantaCruz), Willow Road (east of Middlefield Road) and Ravenswood Avenue (east of ElCamino Real) would be impacted by the project. With the SUMC project, two moreroadways would be affected by the proposed project. These are Marsh Road (west ofUS 101) and Alpine Road (west of Junipero Serra Boulevard). With both the SSC andSUMC 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 ElCamino Real). With the SUMC project, two more roadway segments would be adversely


3-106 January 13, 2009

impacted by the project. These two roadways are Marsh Road (west of US 101) andAlpine Road (west of Junipero Serra Boulevard). With both the SSC and SUMCprojects, the same six roadways would be significantly impacted in 2025.

The cumulative impacts of the projects on the roadways in 2025 are also presented inTable 3-18. It can be seen that the SUMC project would significantly affect six roadwaysegments (Base A). They are Marsh Road (west of US 101), Sand Hill Road (east ofSanta Cruz), Willow Road (east of Middlefield Road), Alpine Road (west of JuniperoSerra Boulevard), Middlefield Road (north of Ravenswood Avenue) and RavenswoodAvenue (east of El Camino Real). These same roadway segments, except Marsh Roadand Alpine Road, would also be adversely impacted by the cumulative effect of the SSCproject (Base B).

These roadway segments were also evaluated using the TIRE index, consistent with theCity of Palo Alto procedures. None of these roadway segments exceeded the TIREindex thresholds as seen in Table 3-19. Therefore, according to City of Palo Altostandards, no roadway segments are considered to be impacted to a significant level.

3.8 Parking AnalysisThe 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 todetermine if the project has sufficient parking.

3.8.1 SUMCThe proposed SUMC expansion includes the Stanford Hospital and Clinics (SHC), theLucile Packard Children’s Hospital (LPCH) and Medical Office Buildings (MOB). TheSHC project component included 1,100,000 square feet of new hospital space and429,000 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 beremoved. 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 medicalprofession that does not accommodate additional patients or staff and therefore does notgenerate additional traffic. The net development of SHC is 228,200 square feet ofhospital space and 315,700 square feet of clinic space for a total of 543,900 square feetof additional development. Details of the parking evaluation are presented in AppendixG1.

The LCPH project component includes 471,300 square feet of new hospital space and50,000 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 hospitalspace and 50,000 square feet of clinic space, for a total of 395,300 square feet ofadditional development. Both the SHC and LPCH have a net additional area of 854,670square feet combined. The MOB component of the project consists of the removal of56,300 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 theparking demand rate determined through the survey conducted on existing parkingconditions, 913 spaces would be needed for the hospitals in 2015 and 1,522 spaceswould be needed in 2025. Taking into account a 10-percent supply buffer to ensure thatdrivers are able to locate parking spaces without excessive re-circulating through theparking area, the parking demand at hospital is calculated to be 1,005 in 2015 and 1,674in 2025. Taking away spaces available from current vacancies, new parking spacesneeded for the hospital would be 747 in 2015 and 1,416 in 2025. This is similar to theCity’s parking ordinance requirements and is greater than the parking demandcalculated according to ITE statistics. For the MOB, 577 spaces would be needed tomeet 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 withoutexcessive re-circulating through the parking area, the parking demand at MOB stands at635 in both 2015 and 2025. The total demand for SUMC in 2015 is estimated to be1,382 spaces and 2,051 in 2025. The proposed number of parking spaces is 2,180 in2015 and the proposed provision is 2,985 spaces in year 2025. These spaces would bedistributed around the five parking structures in the hospital area. The total parkingsupply in 2025 is allocated at 2,051 for SUMC and 932 as replacement parking forexisting spaces demolished for project construction. The replacement parking isseparated in 871 spaces removed plus a 10 percent vacancy factor. Appendix G2summarizes the parking demand and replacements. Therefore, proposed parkingequals estimated parking demand plus a 10 percent buffer.

3.8.2 SSCThe SSC project is divided into three main categories. There is a 120-room hotel, a highquality 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 of1,199 new parking spaces are being proposed for the SSC project, making the totalnumber of parking spaces for the SSC 7,000. This number is lower than the 10,362spaces required based on the City’s parking ordinance and the 8,134 spaces calculatedusing ITE parking generation rates. However, the existing shopping center has 5,801parking spaces, whereas the City code projects a demand of 7,061 spaces for existinguses. The difference between these two values, added to the proposed 7,000 spacesresults in 8,260 spaces, or approximately equal to the ITE estimated demand. Assumingthe percent shared parking results in parking supply slightly less than ITE demand figurewould indicate. Given the SSC is located near a major transit hub, parking supply meetsestimated demand. Details are provided in Appendix G3.

3.9 Project Site Local Circulation AnalysisThe SUMC project will result in several changes to local access and circulation. While to agreat extent, the project will rely on the existing roadway network, there are changes to thatnetwork 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 thecapacity of Pasteur Drive. The following discusses the individual components of the roadwaynetwork.

Welch Road

Welch Road between Quarry Road and Pasteur Drive currently has 29 driveways, of which 4are closed. The remaining 25 driveways provide for a combination of inbound, outbound, andtwo-way access to the individual land parcels along Welch Road. The current traffic volumesare 11,375 vehicles per day, as measured in Fall 2008. Pedestrian crossings of Welch Roadare concentrated at three locations, near the Stanford Barn and on both sides of the LPCHparking structure access. Hourly pedestrian volume at these three crossings was observed atapproximately 200 persons during the midday, the time of greatest pedestrian activity. None ofthe 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 leftturns tend to increase congestion by restricting through traffic when opposing left turn queuesblock each other. The existing constraints to capacity on Welch Road include the side frictioncaused by numerous driveways and slow traffic turning into and out of the driveways, left turnsblocking the through traffic movements and frequent pedestrian crossings. The ‘with project’scenario includes some modifications to Welch Road to improve traffic flow and accommodatethe future traffic volumes from the hospital expansion. Under the With Project scenario, WelchRoad will be a 3-lane roadway with on-street bike lanes. There will be one through lane in eachdirection (11-foot through lanes), with a two way left turn lane in the center (12-foot center leftturn lane). The bike lanes will be six feet wide, including the gutter. Right turns into drivewayswill 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 levelof traffic on a two-way roadway with a continuous two way left turn lane in the median isapproaching the capacity of the roadway. The three pedestrian crossings are proposed to becombined into one or two locations. The main pedestrian crossing at the LPCH access will besignalized. Signalization of the pedestrian crossing will improve the capacity of Welch byconcentrating crossings into specific time segments, rather than the current operation wherepedestrians cross individually or in smaller groups nearly continuously. The three locations withoverlapping left turns are removed. The conflict at 703 and 730 Welch Road is eliminated withthe realignment of the driveways. The conflict at 780/800 Welch and 777/801 Welch iseliminated by closing a driveway. The conflict at 1110 Welch and 1101 Welch is eliminated bymoving the access to 1101 Welch onto Durand. Driveways in the vicinity of the Quarry Roadintersection would be restricted to right in and right out only. A center barrier median will beconstructed between Quarry Road and the entrance to LPCH to prevent left turns to and fromthe driveways. The barrier median will also improve the capacity of Welch Road. A computersimulation was made of traffic and pedestrian movements along Welch Road. That simulationdemonstrated that the modified roadway design proposed as part of the project improves trafficflow.


3-114 January 13, 2009

Durand Way

An extension of existing Durand Way from Sand Hill Road to Welch Road is proposed as part ofthe 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 thebike lanes are 6 foot, including the gutter. This design will enable left turn queues to extendfrom Sand Hill Road back to Welch Road, or the reverse. Both Sand Hill/Durand andWelch/Durand would be signalized. At Sand Hill Road, the two westbound lanes on DurandWay should be a left and a through/right. This lane striping will keep the queues from extendingback to the Welch Road intersection. At Welch Road the two lanes on Durand Way should bestriped for a right and a through/left. The two traffic signals on Durand Way should beinterconnected. The signal cycles on Sand Hill Road range from 120 to 140 seconds tomaximize through travel on Sand Hill Road. The signal cycle lengths on Welch will not be aslong. Instead, the cycle lengths at Welch/Durand should one-half of those on Sand Hill tomaintain coordination. The extension of Durand Way to Sand Hill Road provides traffic relief toPasteur Drive and to Welch Road. Durand Way was included in the computer simulation andacceptable traffic operations are expected. Queue lengths were also calculated usingTRAFFIX. Adequate storage is provided to accommodate vehicles between these twointersections.

Quarry Road Extension

An extension of Quarry Road is proposed to provide access to hospital parking. At theapproximate location where existing Quarry Road turns to connect to Campus Drive West, theQuarry Road extension will continue south to Roth Way. The Quarry Road extension will be atwo-lane roadway with on-street bike lanes. Lane widths will be 11 feet with 6-foot bike lanesincluding the gutter. The connection to existing Quarry Road would be stopped controlled forthe Quarry Road extension leg.

Roth Way

Roth Way will connect Campus Drive West to the Quarry Road extension. This connection willprovide 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 tothe underground parking garage. On-street parking will be removed from Pasteur Drive and theroadway will provide two lanes of travel in each direction with on-street bike lanes. Travel laneswill be 11 feet with 6-foot bike lanes including the gutter.

Service Connection Between Campus Drive West and Pasteur Drive


3-115 January 13, 2009

A private street connection is proposed between the intersection of Roth Way/Quarry RoadExtension and Pasteur Drive. Stanford has indicated that this service road would be for limitedaccess (emergency vehicle, transit, service). This roadway makes a connection between SandHill Road at Pasteur Drive and Campus Drive West at Roth Way. As such it enhances the gridpattern of the local street network. Local circulation could be improved with this roadway opento all traffic as a public street.

3.10 Transit ImpactsThe SUMC and SSC projects cause an increase in the level of traffic congestion at severallocations throughout the study area. While mitigation measures such as roadway improvementsand TDM measures have been identified to alleviate some of the traffic impacts, implementationof many of the traffic improvements are either infeasible or undesirable and TDM measures donot fully mitigate the traffic impacts. Impacts to transit service in the study area because ofcongested intersections are considered a significant impact according to City of Palo Altocriteria and occur as a result of both projects by 2015. The impacts increase as additionalproject expansion occurs by 2025. Using trip generation values to establish the impact of eachproject on the transit system results in a SSC contribution in 2015 of 42 percent versus 58percent for SUMC. The split is 31 percent for SSC and 69 percent for SUMC in 2025.

3.11 Transportation Demand Management ImpactsThe proposed developments are currently served by the Marguerite shuttles that connect to thePalo Alto and California Avenue Caltrain stations. Other transit service to the Caltrain stationsand the shopping center that provide connecting service to the Marguerites include SamTransRoutes RX, 280, 281, 297, 390, 397, and KX; VTA Routes 22, 35, 89, and 522; the U Line fromthe East Bay; and the Palo Alto shuttles. Development of the expanded shopping center andhospital would increase demand for transit service in the area. Also, the TDM measuresproposed for the hospital (provision of GO Passes for all employees) will increase transitridership. The mode split to transit for the existing hospital is 8.9 percent according to Stanforddata. 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 hospitalemployees are provided with GO Passes. The mode split to transit for the shopping centerwould probably be no more than 1 or 2 percent. A total of 71 to 165 AM and 79 to 170 PM peaktransit trips would be created by the project, depending on the success of the GO Pass. Giventhe high level of transit service to the surrounding area, increased transit ridership could beaccommodated by the existing routes, with three possible exceptions. Expansion of the GoPass program to all hospital employees will increase ridership on the Marguerite shuttles, mostnotably Line A and Line B Counter-Clockwise. Increased ridership on these two routes couldcause a load factor of greater than 1.25. This would be considered a significant impact. Thisimpact is associated with the SUMC project and could occur by 2015 but may not occur untilpost 2015. Historically, Stanford monitors ridership on the Marguerite and adjusts transitservice to meet demand. Monitoring of Lines A and B needs to continue with expansion of theGO Pass program to all hospital employees. Also, the current load factor on the U Line from theEast Bay is approaching 1.0 (0.94 according to AC Transit). The expanded ridership could push


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 asignificant impact. This impact is also associated with the SUMC project and could occur by2015 but may not occur until post 2015. It is also noted that Stanford would increase theMarguerite shuttle services if the ridership increases and this could off-set the potential impactto other transit services. Significant diversion of traffic to alternative modes is not as viable forSSC as for SUMC. Therefore, the impacts to transit as a result of TDM is associated withSUMC, rather than SSC.

3.12 Pedestrians and Bicycles ImpactsPedestrian and bicycle traffic around the hospital and shopping center is currently veryextensive. Expansion of the two projects would increase the level of bicycle and pedestrianactivity. An extensive pedestrian and bicycle network currently exists around the shoppingcenter and hospital. This network should be enhanced in association with the two projects byproviding additional accesses to remove barriers. Figure 3-18 shows the Primary Pedestrianand Bicycle Circulation as currently proposed. Pedestrian and bicycle facilities are provided onnearly all streets in the network. There are also numerous off-road pedestrian-only as well ascombined pedestrian/bicycle facilities.

The study area is conducive to pedestrian and bicycle travel. Downtown Palo Alto, PAITS, theShopping Center, the Medical Center, and the University are all within a 20-minute walk iflinkages are made and barriers removed. The study area has barriers to pedestrian and bicycleaccess to the shopping center and medical center. The Caltrain tracks and El Camino Realseparate the downtown from the shopping center; San Francisquito Creek separates theresidential neighborhoods of Menlo Park from the two projects; and Sand Hill Road separatesthe residential areas to the northwest from the shopping center. The medical office buildingsand the Stanford Barn separate the residential areas from the medical center and the medicalcenter from the shopping center.

While both projects will continue to attract a high percentage of automobile traffic, alternativemodes of travel also need to be addressed. There is an opportunity to attract people from thethree residential neighborhoods that are within ½-mile walking distance to support pedestrianactivity within the projects’ study area. Residents of Sand Hill West and Menlo Park can benefitfrom pedestrian access that links the medical center to the shopping center. Residents indowntown 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 HillRoad.

Additional connections would reduce walking and bicycle travel time between downtown and theshopping center and medical center. The goal of the two projects would be to provide walkingand biking connectivity linking the shopping center, the medical center, the University, PAITS,downtown and surrounding residential neighborhoods, providing an environment thataccommodates alternative modes of travel in addition to auto travel.

A comprehensive approach to providing needed pedestrian and bicycle improvements shouldbe 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 andbicycle impacts.

3.13 Emergency Vehicle Access ImpactsEmergency vehicles require access within the study area to respond to emergencies and also toaccess the SUMC emergency room. Travel time by emergency vehicles would increasebecause of additional traffic congestion associated with the projects. The City’s significancecriteria identify inadequate emergency access as a significant impact. The increased


3-119 January 13, 2009

congestion identified in this analysis due to the SSC and SUMC projects at study areaintersections is considered a significant impact. Table 3-23 lists the intersections at LOS E or Fduring 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 alsoseparated by analysis year. The impact for each project and for each analysis for emergencyaccess is as defined in Table 2-23. Traffic operation at LOS E or F is considered a significantimpact to emergency access.

3.14 Construction ImpactsProject-related construction traffic could contribute to increased intersection delays andinterference with pedestrians, bicyclists, and transit. During the construction period, impactsmight arise from a substantial increase in heavy truck travel, as materials are brought in to theproject sites, and demolished or excavated materials are hauled out. Temporary lane or roadclosures might be required for the construction and for underground utility work. Constructionactivities would lead to both temporary disruption of transportation system operation andpossible 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 fortransporting 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 WelchRoad. From US 101 and the east, either San Antonio Road or Woodside Road would be usedto 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 developedfor each project prior to the beginning of any construction activities. The construction accessplan shall be reviewed and approved by the City. Any deviation from that plan would be asignificant impact. Impact due to construction would be according to the construction activitiesof each project.
