Countywide Transportation Plans

Some counties develop their own long-range plans – countywide transportation plans – to guide transportation decisions in their communities. MTC helps them with cross-regional coordination.

Because each Bay Area county is unique, there is no “one-size-fits-all” approach to transportation planning. Some counties develop their own long-range plans – countywide transportation plans – which are regularly updated to reflect new priorities and new financial estimates.

These plans serve as essential building blocks for the development of MTC’s larger regional transportation plan, [link to 3.2b Plan Bay Area 2040 page]Plan Bay Area[/link]. 

While MTC is required by law to adopt a plan, county congestion management agencies (CMAs) develop their plans voluntarily. And not all Bay Area counties choose to do so.

Strong Participation

Congestion management agencies (CMAs) in eight of the nine Bay Area counties have adopted countywide transportation plans:

  • Alameda County Transportation Commission
  • Contra Costa Transportation Authority
  • Napa Valley Transportation Authority
  • San Francisco County Transportation Authority
  • City/County Association of Government of San Mateo County
  • Santa Clara Valley Transportation Authority
  • Solano Transportation Authority
  • Sonoma County Transportation Authority

MTC works with local CMAs to support their work.

Efficient Planning

MTC works with congestion management agencies to help them reduce duplication of local planning efforts.

Work on countywide transportation plans is coordinated with related work on congestion management plans.

Seven of the nine Bay Area counties submit congestion management plans to MTC for approval.
