Stormwater Management
Fresno enforces stormwater management under FMC Chapter 6, Article 7 (Stormwater Quality Management) and the Central Valley Regional Water Quality Control Board's MS4 permit.

Illicit discharges to the storm drain system are prohibited, and the City conducts dry-weather monitoring of outfalls to the San Joaquin River watershed.

Heavy RestrictionsErosion Control
Fresno requires erosion and sediment control measures for all grading and construction activities under FMC Chapter 15 (Development Code) and the California Construction General Permit. Projects disturbing one or more acres must file a Notice of Intent and prepare a SWPPP with site-specific erosion control BMPs. The City's relatively flat terrain and sandy soils reduce erosion risk compared to hillside areas, but wind erosion and PM10 dust control are significant concerns in the San Joaquin Valley.

Some RestrictionsCoastal Development
Fresno is an inland city located in California's Central Valley, approximately 150 miles from the Pacific coast. The California Coastal Act and coastal development permit requirements do not apply. There is no local coastal development ordinance. Development near waterways such as the San Joaquin River is subject to environmental review under CEQA and potential permits from the Army Corps of Engineers and California Department of Fish and Wildlife.

Few RestrictionsFlood Zones
Fresno has significant flood risk areas along the San Joaquin River, Kings River, and various urban drainage channels. FMC Chapter 11, Article 2 establishes floodplain management regulations implementing FEMA's National Flood Insurance Program (NFIP). Properties in Special Flood Hazard Areas (SFHA) must comply with elevation requirements, flood-proofing standards, and development restrictions. The city's location in the Central Valley between the San Joaquin and Kings River floodplains creates substantial exposure.
