Cannabis Cultivation Regulatory Program
Welcome to the San Francisco Bay Regional Water Board’s cannabis cultivation regulatory program website. We regulate water quality impacts from cannabis grows in the hydrologic region of the San Francisco Bay Area, which approximately corresponds to the nine counties of the Bay Area (map of Regional Water Boards).
In October 2017, the State Water Board adopted requirements for cannabis cultivation to reduce impacts from discharges of waste and water diversions associated with cannabis cultivation activities. Cannabis cultivators are now required to obtain licenses and meet all state and local environmental regulations including the California Water Code and Basin Plan, as well as the new Cannabis Policy and Cannabis General Order. Cannabis cultivation can cause significant environmental damage, including discharges of polluted wastes to surface water and groundwater, erosion and sedimentation of surface water bodies, and illegal diversions of surface water.
Visit the Cannabis Regulatory Programs Registration Portal to enroll for coverage under the Cannabis General Order or to file for a cannabis Small Irrigation Use Registration water right.
