Stormwater Management
Hesperia is a regulated small MS4 under the California State Water Resources Control Board's Phase II General Permit (Order WQ 2013-0001-DWQ as amended). The city's Storm Water Management Program (SWMP) is enforced by the Hesperia Engineering Department. All construction sites disturbing one acre or more must obtain coverage under the statewide Construction General Permit (Order 2022-0057-DWQ) and prepare a SWPPP; smaller residential sites must implement Erosion and Sediment Control Plans (ESCPs). Post-construction Water Quality Management Plans (WQMPs) are required for development projects per the Phase II Permit's post-construction provisions. Discharge of anything other than uncontaminated stormwater into the MS4 is prohibited.
Stormwater & Illicit Discharge — Phase II MS4 Permit (Lahontan Region) Enforced via Hesperia SWMP
Heavy RestrictionsErosion Control
Hesperia's SWMP requires Erosion and Sediment Control Plans (ESCPs) for construction sites, including single-family residences, to prevent sediment discharge into the Mojave River watershed. Projects disturbing one acre or more must enroll under the statewide Construction General Permit (Order 2022-0057-DWQ) via the State Water Board's SMARTS system and prepare a SWPPP signed by a Qualified SWPPP Developer. Standard BMPs include silt fences, fiber rolls, stabilized construction entrances, soil stockpile covers, and post-construction revegetation.
Erosion & Sediment Control — ESCP + Statewide Construction General Permit
Heavy RestrictionsCoastal Development
Hesperia is an inland city in the High Desert of San Bernardino County, located approximately 85 miles inland from the Pacific coast at an elevation of roughly 3,200 feet. The California Coastal Act of 1976 (Cal. Public Resources Code §30000 et seq.) applies only within the defined coastal zone — Hesperia is far outside that zone, so no Coastal Development Permit (CDP) or Local Coastal Program (LCP) review applies. There is no local coastal-development ordinance because the city is not coastal. State coastal statutes are listed below for completeness.
Coastal Development — Not Applicable (Inland Mojave Desert)
Few RestrictionsFlood Zones
Hesperia regulates development in special flood hazard areas (SFHAs) under Hesperia Municipal Code Chapter 8.28 (Flood Hazard Protections Regulations), implementing the National Flood Insurance Program (NFIP). The city's Floodplain Administrator (Cassandra Sanchez, (760) 947-1059) reviews proposed development in mapped FEMA flood zones. The city's website warns that current FIRMs are out of date and many formerly rural areas lack detailed mapping; a flood map modernization effort is underway. Property-specific flood risk can be checked via the city's GIS viewer at hesperia.geoviewer.io or the FEMA Map Service Center.
Flood Hazard Prevention — HMC Chapter 8.28 + FEMA NFIP
Heavy RestrictionsGrading & Drainage
Hesperia enforces grading and drainage through HMC Title 15 (Buildings and Construction), which adopts the California Building Code (Title 24 CCR Part 2) effective January 1, 2023. California Building Code Appendix J (Grading) governs grading permits, cut/fill slope ratios, drainage terraces, and setbacks from property lines when adopted. Grading permits are issued by the Hesperia Engineering Department; drainage analysis must comply with the city's standard drainage requirements and Water Quality Management Plan (WQMP) post-construction BMPs.
Grading & Drainage — CBC Appendix J + HMC Title 15 Permit
