San Diego Region - Clean Water Act Section 401 Water Quality Certification
Dredge and fill discharges to waters of the U.S. and State are generally regulated through Clean Water Act Section 401 Water Quality Certifications (Certifications) and/or through the California Water Code via waste discharge requirements issued by the San Diego Water Board and the State Water Resources Control Board (State Water Board).
The San Diego Water Board Dredge, Fill, and Wetlands Program protects all waters within its region, but has special responsibility for wetlands, riparian areas, and headwaters because these water bodies have high resource value, are vulnerable to filling, and are not systematically protected by other programs.
For more information regarding the jurisdictional area of each Regional Board, please see this map. The State Water Board is responsible for issuing permits for projects located in more than one Water Board region. For more information regarding multi-regional projects, please visit the State Water Board website.
