Introduction
This report presents a Transportation Demand Management (TDM) Plan, per City of South San Francisco
Zoning Code Chapter 20.400, for the proposed research & development buildings known as the Infinite
101 Project, herein referred to as the “Project.” A description of the proposed project is included on the
following pages.
The City of South San Francisco TDM Ordinance strives to accomplish the following goals:
• Reduce the amount of traffic generated by new nonresidential development.
• Ensure that expected increases in traffic resulting from growth in employment opportunities
in the City of South San Francisco will be adequately mitigated.
• Reduce drive-alone commute trips during peak traffic periods by using a combination of
services, incentives, and facilities.
• Promote the more efficient utilization of existing transportation facilities and ensure that new
developments are designed in ways to maximize the potential for alternative transportation
usage.
• Establish an ongoing monitoring and enforcement program to ensure that the desired
alternative mode use percentages are achieved.
The City requires the Project to enact a TDM program to achieve a maximum drive alone commute mode
share of 50 percent pursuant to the City’s Municipal Code Chapter 20.400. Additionally, the Project
must implement annual monitoring of a site-specific trip cap. These requirements are consistent with
a Tier 4 classification (large office/R&D project) under the TDM Ordinance and also meet the TDM
requirements established by the City/County Association of Governments of San Mateo County
(C/CAG).
This TDM Plan identifies a set of strategies, measures, and incentives to encourage future tenant
employees at the Project to walk, bicycle, ride transit, or carpool when commuting to and from work.
In order to accomplish this goal, this plan presents a range of proven strategies and measures used
across the Bay Area.
Project Description
The Project includes 669,014 square feet of R&D space, 9,055 square feet of conference space, and dining
and fitness amenities which are expected primarily to serve other users of the site. The Project includes
1,300 parking spaces. The Project is located in South San Francisco’s Lindenville District just off Produce
Avenue immediately west of US 101 and north of the Navigable Slough. Site access would be provided for
vehicles, pedestrians, and bicyclists via Infinite Court off Produce Avenue and via a right-of-way
connection to Shaw Road.
Figure 1 illustrates the Project location, while Figure 2 depicts site circulation.

Project Setting
Transit Connections
The following transit services operate within South San Francisco near the Project site. Existing transit
services are shown in Figure 3. Descriptions provided in this section reflect transit operations in Spring
2023.
BART
BART provides regional rail service between the East Bay, San Francisco, and San Mateo County, with
connections to San Francisco International Airport and Millbrae Intermodal Station to the south, San
Francisco to the north, and Oakland, Richmond, Pittsburgh/Bay Point, Dublin/Pleasanton and Fremont in
the East Bay. Two BART lines serve South San Francisco Station: the Yellow Line connecting Antioch with
San Francisco International Airport, and the Red Line connecting Richmond and Millbrae. Each BART line
operates every 15-minutes throughout the day. The closest station is San Bruno BART Station, located
approximately one mile southwest of the Project site in neighboring San Bruno.
Caltrain
Caltrain provides passenger rail service on the Peninsula between San Francisco and San José, and limited
service to Morgan Hill and Gilroy during weekday commute periods. The South San Francisco Caltrain
Station is located approximately one mile north of the Project site and San Bruno Caltrain Station is
located approximately one mile south of the Project site in neighboring San Bruno. Both stations are
served by local and limited trains from around 5:00 A.M. to 12:30 A.M., with approximately 30-minute
headways during peak periods and 60-minute headways during off-peak periods. In early 2022, Caltrain
relocated the South San Francisco Caltrain station several hundred feet to the south to provide a more
direct connection to downtown South San Francisco. By 2024, Caltrain plans to complete its electrification
project to support the operation of faster and more frequent rail service on the Peninsula, and expects to
modify its schedules accordingly.
WETA (San Francisco Bay Ferry)
The Water Emergency Transportation Authority (WETA) provides weekday commuter ferry service
between the Oakland/Alameda ferry terminals and the South San Francisco Ferry Terminal at Oyster Point
(known as the San Francisco Bay Ferry). There are three morning departures from Oakland/Alameda to
South San Francisco, and three evening departures from South San Francisco to Oakland/Alameda. The
South San Francisco Ferry Terminal is located approximately 3 miles to the northeast of the Project site.
SamTrans
SamTrans provides bus service in San Mateo County. There are no existing SamTrans bus stops within a
reasonable walking distance of the Project site.

First/Last Mile Shuttle Connections
There are currently no existing shuttles serving the Project site.
Bicycle and Pedestrian Connections
The Project site is located adjacent to US 101, a navigable slough, and existing industrial and parking
facilities, which heavily constrain bicycle and pedestrian connectivity. Produce Avenue has a continuous
sidewalk along the west side of the street that connects to the intersection with San Mateo Avenue and
Airport Boulevard. People walking or biking to or from the site currently must use this route. At buildout,
the Project has proposed a new trail connection with Shaw Road. Shaw Road has a sidewalk on the north
side of the street to the west of the right-of-way and on the south side of street in both directions; there
is no existing street crossing of Shaw Road at the right-of-way.
While the City continues to expand its bicycle and pedestrian network, the area surrounding the Project
has historically experienced low volumes of pedestrians and bicyclists due to commute lengths, lack of
continuous low stress facilities, and lack of network connectivity to residences and transit stations.
To address the gap in the bicycle and pedestrian network near the Project site, the City has proposed a
bicycle and pedestrian bridge and trail in the vicinity of the Project site in its Active South City Bicycle and
Pedestrian Master Plan. The trail would connect the Bay Trail and Centennial Way Trail via the Navigable
Slough, Shaw Road, and an eventual grade separation of Caltrain at Tanforan Avenue. Figure 5 illustrates
existing and planned bikeway facilities as well as sidewalk infrastructure gaps in South San Francisco.
San Mateo County TDM Resources
The Project would have access to trip reduction services offered by Commute.org. Commute.org is a
public agency whose mission is to reduce the number of drive-alone vehicles traveling to, from or through
San Mateo County. The agency’s goal is to help residents and commuters find alternatives to driving
alone that are less stressful, less costly, and better the environment. The agency provides information and
commute planning assistance to employees, employer programs, and city transportation demand
management partnerships. Commute.org also provides first/last mile shuttle services in the East of 101
Area. Figure 4 illustrates some current promotions and services offered by Commute.org that are open to
all employees in San Mateo County.

Proposed Transportation Demand
Management Program
This section summarizes the Project’s proposed TDM program as presently envisioned in the planning
process. When applying for a Certificate of Occupancy, the applicant shall submit a compliance form and
appropriate attachments finalizing the TDM program and documenting how the program will be
implemented before the site reaches 50% occupancy.
Proposed TDM Program
The City’s TDM Ordinance has two components: a points-based planning checklist and annual
performance monitoring thresholds. As a Tier 4 project, the Project is required to submit a completed
TDM checklist that achieves a minimum threshold of 50 points, consistent with achieving a 50 percent
drive alone mode share target (via survey) and compliance with an onsite trip cap (via counts).
As illustrated in Table 1, the Project would implement all required measures per the City’s TDM Ordinance,
including the following:
▪ 50% Transit Pass Subsidies and Pre-Tax Transit Benefits
▪ Participation in Commute.org Programs
▪ Carpool/Vanpool Programs and Parking
▪ Bicycle Storage, Showers, and Lockers
▪ Designated TDM Coordinator
▪ Bicycle and Pedestrian-Oriented Site Access
▪ Encourage Telecommuting & Flexible Work Schedules
The Project would also implement the following optional measures:
▪ Enhanced Shuttle Commitment
▪ Fully Subsidized Transit Passes
▪ Active Transportation Gap Closure
▪ Transit Capital Improvements
▪ On-Site Pedestrian-Oriented Amenities
▪ Bicycle Repair Station
Each measure is described in detail below.
11
Participation in Commute.org Programs
The Project will partner with Commute.org to provide TDM marketing services and promotions via its
Certified Development Program (https://commute.org/resources/developers/). Commute.org offers a wide
array of programs and marketing support to all eligible employers, property managers, and cities within
San Mateo County. Key services that the Project will participate in include the Commute.org ride-
matching program (designed to aid in carpool and vanpool formation); Guaranteed Ride Home services;
and general educational and promotional programs and materials. The Project’s designated TDM
coordinator will obtain a certificate of participation from Commute.org each year as part of the annual
monitoring and reporting process.
Carpool/Vanpool Programs and Parking
The Project will ensure that employer tenants offer carpool and vanpool programs that include subsidies
or other monetary incentives (e.g., gas card after carpooling for a given amount of time, or parking
subsidies for carpools), dedicated carpool and vanpool parking, as well as ride-matching services to help
facilitate these shared trips. Elements of the carpool program (such as use of the regional ride-matching
program) will be provided in partnership with Commute.org.
Bicycle Storage, Showers, and Lockers
The Project will provide safe and convenient bicycle parking per City code requirements, as well as
showers, changing rooms, and lockers. The Project is proposing to provide short-term bicycle parking
spaces and long-term bicycle parking spaces in excess of code requirements. Short-term bicycle parking
will be located near main building entrances and will be easily accessible.
Designated TDM Coordinator
The Project will designate a TDM coordinator. This individual may either be an employee of the Project’s
property management or contracted through a third-party provider. The TDM coordinator shall provide
oversight and management of the program’s implementation.
In addition, the TDM coordinator will provide lists of mandatory and optional measures to all individual
businesses. Tenants will be obligated (via lease language) to provide a point of contact for the Designated
TDM Coordinator. The TDM Coordinator, in turn, will verify that tenants are implementing all required
measures as part of the annual monitoring and reporting process.
Bicycle and Pedestrian-Oriented Site Access
The Project will enhance bicycle and pedestrian access by providing new connections and onsite
circulation paths. The Project will provide pedestrian walkways between all core buildings and bicycle
routes through the site. Bicycle access will primarily be provided via a new trail along the Navigable
Slough connecting to Shaw Road.
12
Encourage Telecommuting & Flexible Work Schedules
The Project shall encourage employers to allow telecommuting at least one day per week to reduce
overall vehicle trips, unless an employee’s job functions cannot be performed from a remote location.
When employees commute to work, employers shall encourage flexible work schedules that help shift
travel outside of peak hours. Uptake of remote work, telecommuting, and flexible work schedules will be
monitored via survey.
Enhanced Shuttle Commitment
The Project will provide first/last mile shuttles to the San Bruno BART Station and South San Francisco
Caltrain Station. Since no shuttle routes are present near the Project site, the Project sponsor will establish
new routes. A minimum of one vehicle would be dedicated to each route (two vehicles total) with service
at least every 15 minutes during the AM and PM peak periods (totaling a minimum of six hours per day).
Shuttles will be free and open to the public. The Project sponsor is encouraged to work with
Commute.org as a shuttle manager and participate in the San Mateo County Transportation Authority’s
Shuttle Call for Projects grant program. The proposed shuttle routes are shown in Figure 6.
Fully Subsidized Transit Passes
The Project will offer public transit passes or subsidies up to the IRS transit benefit maximum (currently
$280 per person per month). This may be implemented through either a direct voucher program provided
by the property manager, or through lease terms obligating employers to provide said subsidies. Should
the measure be implemented through lease obligations, the designated TDM coordinator will be
responsible for confirming that all employers are offering said benefits as part of the annual monitoring
and reporting process.
Active Transportation Gap Closure
The Project will contribute toward a bicycle and pedestrian connection across US-101 linking the Bay Trail
and the East of 101 Area with Shaw Road and the Lindenville area. The Project will prepare an engineering
analysis of the potential trail crossing alignments and incorporate the preferred alternative alignment into
the proposed Project.
The Project will also contribute to active transportation gap closures at intersections adjacent to its
driveways at Produce Avenue/Terminal Court/US-101 Onramp and Produce Avenue US-101 Southbound
Off-Ramp. These improvements would include upgrades to sidewalks, crosswalks, and traffic signals as
described in the Transportation Impact Analysis.
Transit Capital Improvements
The Project will incorporate a new on-site shuttle stop with shelters. The shuttle stop will be centrally
located and convenient for people to access main building entrances.
13
On-Site Pedestrian-Oriented Amenities
The Project will include a restaurant, gym, and conference center onsite to help reduce offsite trips.
Bicycle Repair Station
The Project will include at least one bicycle repair station that will include a toolkit and air pump within a
designated secure area of a building to encourage bicycling and support employees and residents.
TDM Checklist
Based on the required and optional measures described above, the Project would meet the required 50-
point threshold for Tier 4 projects as illustrated in Table 1.

Proposed Trip Cap
Tier 4 projects are subject to site-specific trip caps that limit the number of peak-direction vehicle trips
that a site generates during peak periods. Trip caps should reinforce mode share and parking
requirements for the site while allowing some flexibility to accommodate fluctuations in employee
density, daily variations in travel patterns, and anticipated levels of guest/visitor travel activity. The
proposed trip cap is 1,550 peak period, peak direction vehicle trips, based on the calculations below
(values rounded to the nearest 10):
• Maximum potential onsite occupancy: 2,870 people (inclusive of employees and visitors)
• Target 50% drive-alone rate: 50% x 2,870 people = 1,435 vehicle trips
• Target 12% carpool rate: 12% x 2,870 people / 3 people per vehicle = 115 vehicle trips
• Peak period trip cap: 1,435 + 115 = 1,550 vehicle trips

Monitoring and Enforcement
The TDM program will be monitored based on the requirements in the South San Francisco TDM
Ordinance. The Project would comply with any future changes to the City’s monitoring and enforcement
practices as described in its TDM Ordinance.
Monitoring Methods
Survey monitoring would apply to commute trips only. Participants are expected to provide a good faith
effort in reducing non-commute trips, but these trips would only be monitored via vehicle trip counts.
Survey Approach
Mode share will be monitored via an annual survey to all employees to ensure the Project is meeting its
target goal. Each year, the survey will achieve a response rate equal to either 51 percent of employees or
large enough to identify the current drive alone mode share +/- 5 percentage points, at 95% confidence.
An example of a typical commute survey is included in the appendix; the City of South San Francisco (or a
designated agent) shall ultimately prepare the final surveys and work with the designated TDM
Coordinator to distribute surveys and coordinate with employer tenants. The site’s TDM coordinator may
expand upon this survey language to seek additional information as needed.
In order to calculate drive alone mode share, the TDM coordinator and City staff would sum the total
number of trips completed via the following modes:
• Drove a car or motorcycle alone
• Dropped off by a friend/family member
• Dropped off by Uber, Lyft, taxi, etc.
• Non-responses if greater than 25 percent of the site’s employee population
Trip counts would be included with the annual survey results and summarize total trips, AM peak period
trips into the site (6:00 AM to 10:00 AM), and PM peak period trips out of the site (3:00 PM to 7:00 PM). In
all instances, participants in the program must provide raw data to the City as part of their compliance
package, including:
1. Respondent-level survey response data (deletion of columns containing emails or non-required
fields is acceptable)
2. Count data as delivered by the contractor providing the counts for each location, with data
separated into 15-minute increments or smaller.
3. Current employee population
17
Trip Cap Monitoring
Trip cap compliance would be monitored via annual vehicle counts at all Project access points. Counts
would be conducted by an independent vendor over a period of one week during which school is in
session.
Reporting
As a Tier 4 project, the Project will be required to prepare and submit to the City an annual compliance
form documenting the continued implementation of TDM measures, for the lifespan of the Project. In
addition to the compliance form, counts and survey results would be provided to the City in a
standardized format as specified by staff. Formatted reports would be optional but not required.
Triennial Midday Parking Occupancy Survey
In addition to annual surveys and trip counts, the Project shall prepare a midday parking occupancy count
every three years per City Ordinance requirements. The parking occupancy survey shall be for
informational purposes and is not associated with a performance target.
Enforcement & Fines
The TDM Coordinator may use information from the employee surveys to adjust existing or implement
new TDM program measures. If the alternative mode use goals are not achieved, the TDM Coordinator
will provide an explanation of how and why the goal has not been reached and a detailed description of
additional measures (or intensified marketing or implementation of existing measures) that will be
adopted to reach the required mode use. Following three consecutive years of failure to meet the
performance target, the Project shall pay any non-compliance fees and fines assessed by the City, as well
as continue to make changes to the TDM program in an effort to reach compliance.
If the Project does not meet the required performance targets, the following penalties shall apply per the
TDM Ordinance:
▪ First Violation: The City will direct the Project to modify its TDM program to achieve compliance.
Modifications are likely to include adding or modifying TDM measures to increase mode shift.
▪ Second Violation: The City will direct the participant to coordinate with Commute.org or retain an
independent consultant to identify additional program modifications to achieve compliance.
Modifications are likely to include adding or modifying TDM measures to increase mode shift.
▪ Third Violation (and any subsequent violations): The City may assess a penalty per the City’s fee
schedule. Penalties shall be assessed for each additional violation in subsequent years.
The Project may appeal the decision to administer a penalty if special circumstances prevented meeting
the required performance targets.
