The Contra Costa County Regional Alternative Compliance Joint Powers Authority (RAC JPA) is an independent public agency formed by twelve initial participating municipalities. Our mission is to administer the Contra Costa County Regional Alternative Compliance (RAC) System—a program designed to offer flexible, cost-effective, and scientifically defensible options for stormwater compliance under the Municipal Regional Permit issued by the San Francisco Bay Regional Water Quality Control Board.
The RAC JPA is a separate legal entity established under California’s Joint Exercise of Powers Act. It brings together local governments and agencies to collectively manage and implement the RAC System. Through this collaboration, the JPA enables regulated developments and public agencies to purchase “compliance units” in green stormwater infrastructure (GSI) projects constructed throughout Contra Costa County. These units help meet stormwater treatment requirements when on-site implementation of GSI projects is infeasible.
The RAC JPA welcomes new public agencies as members. Adding a new member requires approval by three-quarters of the Board. New members join by executing the Joint Powers Agreement and may be asked to contribute financially to recognize the efforts of the initial member agencies. As the JPA grows, it can expand the boundaries of its Community Facilities Districts to include new member territories, ensuring broad access to RAC System benefits.
