Stockton, CA Environmental Rules: Erosion Control (2026)

Chapter 15.48 of the Stockton Municipal Code (the 'Grading and Erosion Control Ordinance') is part of Title 15 Buildings and Construction and is administered jointly by the Building Official and the City Engineer. A Grading and Erosion Control Permit is required for all construction projects that disturb soil, except for projects specifically exempted by SMC §15.48.090 (e.g., very small disturbances, agricultural operations). The ordinance implements the federal Clean Water Act by requiring effective control of erosion, sediment and pollutants to protect watercourses, water bodies and wetlands. Permit applications must be filed with the Director and include, as applicable, environmental review documents, conditions of approval, a state Notice of Intent (NOI), a Stormwater Pollution Prevention Plan (SWPPP), an Erosion and Sediment Control Plan (ESCP), and grading plans. Sites that disturb 1 acre or more must file an NOI with the State Water Resources Control Board under the Construction General Permit (CGP) and submit a copy to the City before a grading permit will issue. The permit holder is responsible for installation, maintenance and monitoring of erosion and sediment controls (silt fences, fiber rolls, inlet protection, stabilized construction entrances, etc.) for the duration of soil disturbance.
