What Sonoma County Transportation Authority, Regional Climate Protection Authority (SCTA/RCPA) does

The Sonoma County Transportation Authority, operating jointly with the Regional Climate Protection Authority (SCTA/RCPA), is a California joint powers authority established in 1990 to coordinate regional transportation planning and climate protection across Sonoma County. The agency is governed by a twelve-member Board of Directors representing each of the nine cities in Sonoma County—Cloverdale, Cotati, Healdsburg, Petaluma, Rohnert Park, Santa Rosa, Sebastopol, Sonoma, and Windsor—plus the Sonoma County Board of Supervisors. With a staff of approximately 20, SCTA administers the Measure M transportation sales tax and Go Sonoma Act funding programs, develops long-range planning documents including the Comprehensive Transportation Plan (Sonoma Moves 2050), and leads safety initiatives such as Vision Zero and Safe Routes to School.

The agency's core product portfolio spans transportation funding programs (Go Sonoma, Measure M, Transit Coordinated Claim), planning documents and initiatives (Comprehensive Transportation Plan, SHIFT Sonoma County, Countywide Active Transportation Plan), highway infrastructure projects (Highway 101, State Route 37, Highway 116/121), and operational programs including Redwood Bikeshare, Commute 37 rideshare, Emergency Ride Home, and the Bicycle and Pedestrian Count Program. Technology infrastructure consists primarily of web-based public information systems, interactive ArcGIS-based mapping tools, and a YouTube-hosted meeting archive. Underlying technical capabilities are centered on regional transportation data aggregation (travel behavior studies, forecasting, disadvantaged communities mapping) rather than proprietary software platforms.

As a government entity, SCTA/RCPA generates no commercial revenue. Its funding comes from federal and state grants, the local Measure M transportation sales tax, and administrative allocations. In 2024 alone, the agency oversaw over $80 million in transit and local transportation allocations, supported a successful $81 million state rail extension award to SMART, and secured $4.58 million in federal Safe Streets and Roads for All funding. The 2026 funding cycle contemplates $118 million in transportation project investments. The agency is led by Executive Director James Cameron (appointed October 2023), who serves concurrently as executive of RCPA.

Its core activities involve administering funding programs, developing long-range transportation and climate plans, managing highway corridor projects (SR37, Highway 101), running safety and active transportation programs (Vision Zero, Safe Routes to School, Redwood Bikeshare, Commute 37), and convening regional stakeholders through a twelve-member Board of Directors and technical advisory committees.

Product overview

SCTA/RCPA is a collaborative government agency managing transportation planning and climate protection for Sonoma County. The organization operates a portfolio of interconnected programs including transportation funding mechanisms (Go Sonoma, Measure M), planning documents (Comprehensive Transportation Plan), safety initiatives (Vision Zero, Safe Routes to School), highway projects (SR37, Highway 101), alternative transportation programs (Commute 37, Redwood Bikeshare, Bicycle & Pedestrian Count Program), and climate planning (SHIFT Sonoma County). These programs work together to maintain and improve the regional transportation network while reducing GHG emissions and preparing for climate impacts.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Metropolitan Transportation Commission (MTC): MTC is the Bay Area's regional transportation planning and funding body, operating one level above SCTA with overlapping responsibilities in congestion management, transit funding, and federal/state grant distribution. It is comparable as the umbrella forum for the same Bay Area transportation priorities SCTA engages in.
• Southern California Association of Governments (SCAG): SCAG is California's largest regional planning body, producing long-range transportation plans and distributing federal transportation funds. It is a much larger-scale analog of SCTA's planning, funding-distribution, and interjurisdictional coordination mandate.
• Sacramento Area Council of Governments (SACOG): SACOG is the MPO for the six-county Sacramento region, distributing regional transportation funding and producing long-range plans. Comparable in regional planning and funding-distribution functions, though it covers a larger multi-county geography.
• Santa Clara Valley Transportation Authority (VTA): VTA combines transit operations, congestion management, and capital funding in a single county-level agency. It is comparable in mandate breadth and Bay Area context, though significantly larger in scale.

Direct peers

• Solano Transportation Authority: Solano Transportation Authority is a Joint Powers Authority that coordinates planning and funding across Solano cities and the County. It shares the joint-powers structure, sales-tax funding model, and interjurisdictional coordination role that define SCTA.
• Marin County Transportation Authority: Marin County's transportation authority shares governance characteristics with SCTA and is an explicit co-partner on Highway 101, SR 37, and the Commute 37 rideshare program. It is one of SCTA's closest comparables in scale, structure, and overlapping service territory.
• Napa Valley Transportation Authority: Napa's county-level transportation authority uses a sales-tax-based funding model similar to Measure M and operates planning, funding, and coordination functions for its member jurisdictions. Comparable size, mandate, and funding mechanism make it a strong functional analog to SCTA.
• Contra Costa Transportation Authority: CCTA administers a countywide transportation sales tax and plans major highway, transit, and active transportation investments, very similar to SCTA's role in Sonoma. Comparable in structure, funding model, and program mix.

Regional players

• Association of Monterey Bay Area Governments (AMBAG): AMBAG is the regional planning agency for the Monterey Bay area, combining transportation, housing, and climate planning under one structure. Comparable to SCTA in combining transportation planning with broader community/climate focus.
• San Mateo County Transit District (SamTrans): SamTrans operates transit and serves as a coordinating transportation body for San Mateo County, sharing the Bay Area regional context with SCTA. Comparable in program scope (transit, paratransit, capital) but with a heavier operational tilt.
