Under San Leandro Municipal Code Title 7, Chapter 7-12 (Grading, Excavations and Fills), §7-12-230 requires Erosion Control, Sedimentation Control, and Drainage Plans prepared by a Civil Engineer and approved by the City Engineer for any project requiring a grading permit.
SLMC §7-12-230 mandates that erosion control, sedimentation control, and drainage plans be prepared by a Civil Engineer and submitted with the grading permit application. The drainage plan must show existing, temporary, and final drainage facilities and must be coordinated with the erosion and sediment control plan. Grading, erosion control, and pollutant control work must be done per the approved plans. A performance bond or other security acceptable to the City Engineer is required where the volume to be graded exceeds 500 cubic yards (SLMC Ch. 7-12, Article on bonds — §7-12 et seq.). Construction sites disturbing one or more acres must also obtain coverage under the State Construction General Permit (Order 2022-0057-DWQ) and prepare a Storm Water Pollution Prevention Plan (SWPPP).
Grading without an approved erosion control plan, or failure to maintain BMPs, is a violation of SLMC Ch. 7-12 enforceable by stop-work order and code citation. The City may draw on the performance bond to complete required work. State Water Board penalties under the Construction General Permit can reach $10,000 per day per violation (Water Code §13385) for sediment-laden discharges to waters of the United States.
