Tulare, CA Environmental Rules: Grading & Drainage (2026)

Under Cal. Building Code Appendix J § J103, a grading permit is generally required for cuts/fills exceeding 50 cubic yards or for any work creating a slope steeper than allowed standards (typically 2:1 horizontal:vertical maximum). Appendix J § J106 sets cut setbacks from property lines; § J107 sets fill standards including compaction and benching; § J109 governs drainage and terracing — runoff must be collected and conveyed to an approved point of disposal. Tulare's flat Central Valley topography means most grading issues involve drainage rather than slope stability: lots must be graded so that surface water flows away from buildings (per CBC § 1804.4, a minimum 5% slope for 10 feet from foundation, or approved swale). Drainage must not be obstructed and stormwater leaving a site must enter the City's storm drain system or an approved retention/detention facility, not be cast onto neighbors. The City's Engineering Department maintains City Improvement Standards and Technical Specifications for storm drain pipes, manholes, and detention basin design.
