STMP (Development Fee) Information

In 1988 Contra Costa County residents adopted Measure C, a half-cent sales tax measure for transportation projects and programs which voters renewed in 2004 with the passage of Measure J. These ballot measures require that local jurisdictions develop a program of regional traffic mitigation fees, assessments, or other mitigations, as appropriate, to fund regional and subregional transportation projects. In developing these fee programs, local jurisdictions are required to consider such issues as jobs/housing balance, carpool and vanpool programs, and proximity to transit service in the establishment of the regional traffic mitigation program.

West County traffic is heavily impacted by through traffic from other regions in Contra Costa County as well as other counties. The West County Subregional Transportation Mitigation Program (STMP) was developed with the participation and concurrence of local jurisdictions in determining the most feasible methods of mitigating regional traffic impacts. The Cities of El Cerrito, Hercules, Pinole, Richmond, and San Pablo, as well as the County of Contra Costa have each adopted an ordinance implementing this fee program. These jurisdictions share a desire to assure that new development in West County pays its fair-share toward regional circulation and transit improvements that are proportional to the traffic impact the new development will generate. The local fees collected in West County provide congestion relief to mitigate traffic on regional routes and through improved transit service.

Participating jurisdictions are responsible for collecting the STMP fee and forwarding it to WCCTAC. The STMP fee amounts should be listed on each individual jurisdiction’s published fee schedule. Staff from participating jurisdictions will calculate the fee due based on the type and scale of the proposed project.

WCCTAC is empowered to coordinate and administer revenue for the regional transportation improvements funded with these fees. Measures C and J also require that all Contra Costa County jurisdictions participate in the regional transportation mitigation program. Jurisdictions that are not participating in such a program are at risk of losing their annual Measure C (and subsequently Measure J) local street maintenance and improvement funds.

STMP Update

In late 2016, WCCTAC began the process of updating the STMP and its nexus study.  This update has been a multi-step process during which WCCTAC’s staff and consultants have worked closely with the WCCTAC TAC and made periodic check-ins with the WCCTAC Board.  The consultant team developed a series of technical memos which evaluated the 2005/2006 program, reviewed West County existing conditions and growth projections, developed criteria for a project list and identified projects and determined the nexus between the projects and the maximum potential fee that could be charged.  These memos are provided below.  The technical memos are summarized in the Final Report of the 2019 Nexus Update of the STMP Impact Fee.  WCCTAC anticipates that the updated STMP program will become effective July 1, 2019.
