CHAPTER 5 _ TRANSPORTATION DEMAND MANAGEMENT PLAN
A Transportation Demand Management (TDM) Plan was prepared to identify measures to
reduce the number of single-occupant automobile trips generated by the proposed project and
thus reduce its traffic impacts. A TDM Plan is a set of strategies, measures and incentives to
encourage the employees to walk, bicycle, use public transportation, carpool or use other
alternatives to driving alone. TDM measures produce more mobility on the existing
transportation systems, boost economic efficiency of the current transportation infrastructure,
improve air quality, save energy, and reduce traffic congestion.
The TDM plan was developed based on guidelines provided by the City of South San
Francisco and the City/County Association of Governments (C/CAG), the local Congestion
Management Agency for San Mateo County. City of South San Francisco draft guidelines for
TDM programs require that all projects that generate 100 or more trips obtain a goal of 28
percent alternative mode use. C/CAG guidelines require developments to implement TDM
measures that have the capacity to mitigate all new peak-hour trips.
"
City of Soutb San Francisco TDM Guidelines
The City of South San Francisco is developing guidelines that require new projects to
achieve a goal of 28 percent alternative mode use. Appendix D contains the standard base
TDM measures for the City of South San Francisco and their estimated percent mitigation, or
alternative mode use.
City/County Association of Government (C/CAG) TDM Guidelines
C/CAG is the Congestion Management Agency for San Mateo County that develops the
Congestion Management Program (CMP). As part of the land use element of the CMP, all
projects that generate 100 or more net new trips during the AM or PM peak hour are required
to mitigate the impacts of all new generated trips. One of the five possible ways to mitigate
these trips is to implement TDM programs that have the capacity to fully reduce the demand
for new peak-hour trips.
C/CAG has identified acceptable TDM measures with equivalent numbers of peak-hour trips
that will be reduced with implementation of each measure. Measures can be mixed and
matched so that the total number of mitigated trips is equal to or greater than the new peak-
hour trips generated by the project (124 AM peak-hour trips for the proposed project). These
programs, once implemented, must be on-going for the occupied life of the development.
Programs may be substituted, with prior approval of C/CAG, as long as the number of
reduced trips is not reduced.

The C/CAG list of approved TDM measures, the number of mitigated peak-hour trips
associated with each, and the rationale used to determine the number of mitigated trips are
presented in Appendix D.
Transportation Demand Management Plan
The Transportation Demand Management Plan includes appropriate TDM measures that will
satisfy City of South San Francisco and C/CAG guidelines. Table 13 summarizes the TDM
measures for the proposed project and identifies how they meet the City's 28 percent
alternative mode use goal and C/CAG's trip equivalent guidelines. The TDM measures
include:
Providing storage for 15 bicycles
Funding seats on BART shuttle bus to Glen Park BART station
Providing preferential parking for carpools and vanpools
Participating in the Peninsula Congestion Relief Alliance's Guaranteed Ride
Home Program "
Providing promotional programs
Subsidizing transit passes
