Clovis, CA Environmental Rules: Erosion Control (2026)

040 sets the grading standards a subdivider must meet before the City issues a building permit for a new subdivision in Clovis. Subsection A requires a grading plan prepared and signed by a registered civil engineer, submitted to and approved by the City Engineer, showing natural and finished grades, pad and floor elevations, drainage swale directions, retaining wall heights, and existing topography and drainage outside the project boundary. 3 bars inter-parcel 'cross drainage,' requiring each parcel to drain to a public street or an approved drainage facility rather than across a neighboring lot.

4, Grading practices, requires all grading citywide to employ the best available management practices, as determined by the City Engineer, specifically to minimize erosion, sedimentation, airborne dust, and unnecessary grading, with each building site on a sloping parcel individually prepared. 6 lets the City require a bond before grading begins on a site not yet recorded, to cover landscaping and erosion control if the subdivider abandons the project mid-grade. 8 conditions every approved subdivision map on compliance with the grading and erosion-control requirements, including prevention of sedimentation or damage to off-site property, found in Appendix Chapter 70 of the California Building Code. 070 must recommend corrective action and special erosion-control precautions.
