Marin County Transportation Planning and Land Use Solutions Program (T-PLUS)

County of Marin, California

Transportation Agency of Marin

Lead Consultant

2003 - 2010

The Transportation Authority of Marin (TAM) selected CD+A to lead a consultant team to support the Agency's work on the Transportation Planning and Land Use Solutions Program (TPLUS), a planning program sponsored by the Metropolitan Transportation Commission (MTC), the Bay Area's MPO. The TPLUS Program supports Bay Area counties and their local jurisdictions in developing locally-based solutions to issues that arise from poor linkages between transportation and land use planning. In Marin, segregated and spread-out land uses, a limited range of housing choices that poorly matches the income of the county's workforce, and discontinuous networks of roads, sidewalks and bicycle paths, all combine to increase the number and distance of vehicle trips, the perception of omnipresent congestion, and reduced livability.

To address these challenges, the CD+A team developed a program description and rules for a local version of MTC's popular Transportation for Livable Communities Capital and Housing Incentive Programs, both of which support local efforts to implement pedestrian, bicycle, and transit-oriented transportation improvements. The CD+A team worked with an Advisory Committee to develop the goals and policies of the project and outline the local challenges to address in a Pedestrian and Transit-oriented Design (PeD and TOD) implementation Toolkit for Marin County. 

The CD+A team's recent work has included TAM staff support on the administration of the local housing and capital grant programs and finalization of the Toolkit, which was recently published online. The toolkit includes sections on TOD/PeD policies, the planning and design of multi-modal streets and circulation networks, land use choices and densities, and urban design. The TOD and PeD approach reflects the fact that, at this time, transit service in the County is limited to local, commuter, and some high-frequency bus routes.

CD+A has continued to lead outreach efforts including the organization of workshops throughout the county with local jurisdiction staffs to develop solutions to local challenges based on Toolkit resources. Additionally, CD+A has coordinated with on-going planning efforts, developers, and local advocacy groups to encourage the countywide adoption of the goals, policies, and designs developed in the Toolkit process.
