Galt requires grading permits for most earthwork under California Building Code Appendix J. Drainage must be directed to streets or approved retention and cannot cross onto neighboring properties at higher volumes than historical flow.
Grading activity in Galt is regulated under California Building Code Appendix J as adopted locally. A grading permit is generally required when earthwork exceeds 50 cubic yards, when a cut or fill slope exceeds 5 feet in height, or when work occurs near watercourses, wetlands, or steep slopes. Permit submittals require a grading plan showing existing and proposed contours, drainage patterns, erosion control BMPs, and import or export quantities. Drainage must flow to a public street, improved drainage facility, or approved on-site retention. California Water Code Sections 7075 through 7078 codify the civil law rule that downhill property owners must accept natural drainage but upper owners cannot artificially concentrate or increase flow. Galt building inspectors verify final grade drains away from foundations at a minimum slope of 2 percent for the first 10 feet. Engineered drainage plans are required when the site includes retaining walls over 4 feet, cut or fill over 5 feet, or work affecting regulated waterways requiring RWQCB or Corps of Engineers permits.
Unpermitted grading may trigger stop-work, double permit fees, and restoration orders. Unlawful drainage concentration onto neighbors can lead to civil litigation for damages.
