Stockton, CA Environmental Rules: Erosion Control (2026)

070 requires a grading and erosion control permit for every construction project that disturbs the soil, filed with the Director on the City's application form, along with any environmental review documents, conditions of approval, Notices of Intent, Stormwater Pollution Prevention Plans, and grading plans; a public-emergency exception lets work start immediately if the City is notified within 24 hours and a permit application follows within 30 days. 090 exempts projects moving less than 50 cubic yards of material, permitted building excavations, cemetery graves, regulated refuse sites, well excavations, non-disruptive mining and quarrying, engineer-directed exploratory excavations, and agricultural crop production, though exempt projects can still need coverage under the state's General Construction Permit.

080 layers extra requirements on sites disturbing an acre or more: the operator must file a Notice of Intent and the current State Water Resources Control Board fee for each site, submit the resulting waste discharge identification number to the City before a grading permit issues, develop and post a Stormwater Pollution Prevention Plan built from the California BMP Handbooks, name a responsible person the City can reach around the clock, and inspect the site before and after every storm event. 080(C)(9), a site idle for more than 30 days must either keep its best management practices in place or revise its plan for permanent erosion protection, with written notice to the City within 14 days. 110 lets the Director require the same erosion control permit and plan on sub-acre sites found to threaten water quality.
