Sonora regulates stormwater runoff through its grading and drainage provisions. Construction projects must implement best management practices to prevent sediment discharge into local waterways including Woods Creek, a tributary of the Tuolumne River system.
Sonora's stormwater management is governed by municipal code grading and drainage provisions and the Central Valley Regional Water Quality Control Board requirements. Construction projects disturbing one acre or more must obtain a SWPPP (Stormwater Pollution Prevention Plan) under the state Construction General Permit. Sonora's location along Woods Creek, which flows through downtown and into the Tuolumne River watershed, makes stormwater quality particularly important. Post-construction stormwater treatment may be required for larger developments. Low-impact development techniques such as permeable paving, bioswales, and rain gardens are encouraged. The city engineer reviews grading and drainage plans for all building permit applications.
Stormwater violations may result in city code enforcement fines starting at $100 per day. State Water Board violations for unpermitted discharges carry penalties up to $10,000 per day.
