The California Stormwater Authority was formed in 2018 through a Joint Powers Agreement (JPA) between the California State Water Resources Control Board, the Fresno Metropolitan Flood Control District, and the Alameda County Flood Control & Water Conservation District. The California Stormwater Authority will provide facilitation of collaborative stormwater management efforts and research services, as well as develop tools to assist California public and private permittees to comply with construction, industrial, and municipal stormwater permits, including the challenge of funding programs and projects. The California Stormwater Authority products and services will serve as a key component to improve surface water and groundwater quality and enhance California’s water supply.
