West Contra Costa Transportation Commission

STMP Development Fee

The sub-regional transportation mitigation programme, and how the development fee works.

Measure C and Measure J

Why the programme exists

In 1988 Contra Costa County residents adopted Measure C, a half-cent sales tax for transportation projects and programmes, which voters renewed in 2004 with Measure J.

Those measures require local jurisdictions to develop a programme of regional traffic mitigation fees, assessments or other mitigations, as appropriate, to fund regional and sub-regional transportation improvements.

In West County that programme is the Sub-Regional Transportation Mitigation Programme, administered by WCCTC on behalf of its member jurisdictions.

How it works
