The Contra Costa California Stormwater Control Ordinance is a set of regulations and guidelines designed to manage and control stormwater runoff in Contra Costa County, California. This ordinance aims to protect water quality by reducing pollution and preventing stormwater runoff from impacting natural water bodies like rivers, lakes, and streams. The ordinance requires property owners, developers, and construction projects within the county to implement stormwater management measures to prevent the pollution of stormwater runoff.
