Bakersfield, CA Environmental Rules: Erosion Control (2026)

Municipal Code § 15.05.170 amends Appendix J of the 2025 California Building Code to govern "excavation and grading including fills or embankments, and the control of grading site runoff, including erosion sediments and construction-related pollutants" (Section J101.1). The Building Official may order work stopped in writing under Section J101.4 if approved grading is "likely to endanger any public or private property or result in the deposition of debris on any public way or interfere with any existing drainage course," and can require correction of any excavation or fill that has become a hazard under Section J101.3.

Most grading requires a permit, but Section J103.2 lists exemptions: excavation for a permitted structure, cemetery graves, regulated refuse disposal sites, well or utility trench excavation, and mining/quarrying operations that don't affect adjoining lateral support. Section J103.4, a Bakersfield addition, bars the Building Official from issuing a grading permit "unless the proposed land use for the site shown on the grading plan application complies with the provisions of Title 17, entitled 'Zoning,' of the Bakersfield Municipal Code." Plan review fees are charged when plans are submitted (Section J103.5), and a separate grading permit fee applies per Section J103.6, with a required site inspection fee under Section J103.7 when the Building Official finds a visual site inspection is needed to establish drainage requirements.

Section J103.8 makes it unlawful to "own, use, occupy or maintain any site containing unpermitted grading." Larger jobs require a soils report from a registered design professional covering soil distribution, grading recommendations and, where necessary, slope stability studies (Section J104.3), and the Building Director will not approve a building permit on any new-subdivision lot until the final soils report is submitted and accepted.
