About Us

Quick facts about 511 Contra Costa

511 Contra Costa is a comprehensive transportation demand management program, that promotes alternatives to the single occupant vehicle. We encourage what we call “green commutes”, which reduce traffic congestion and improve air quality by maximizing the use of the existing roadway system. Green commute options include carpooling, vanpooling, telecommuting, biking, transit, and walking.

511 Contra Costa is sponsored by all twenty jurisdictions in Contra Costa County, CA, through four regional transportation planning committees – SWAT (southwest county), TRANSPAC (central county), TRANSPLAN (east county), and WCCTAC (west county). Funding for 511 Contra Costa programs and projects is provided primarily by the Bay Area Air Quality Management District’s Transportation Fund for Clean Air, and the local ½ cent sales tax approved by voters in the County in 2004 and administered by the Contra Costa Transportation Authority. A portion of Employer Outreach services and programs are funded by the Metropolitan Transportation Committee’s Congestion Mitigation Air Quality funds.
