Coastal Development: Hesperia vs Rancho Cucamonga
How do coastal development rules compare between Hesperia, CA and Rancho Cucamonga, CA?
Hesperia has fewer restrictions than Rancho Cucamonga.
Hesperia, CA
San Bernardino County
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.

San Bernardino County
San Bernardino County is entirely inland - Mojave Desert, Inland Empire, and the San Bernardino Mountains - with no coastline and no California Coastal Commission jurisdiction. The relevant program is the Floodplain Safety (FP) Overlay in Title 8, Section 82.14, plus the Floodplain Administrator duties in Section 86.04, requiring a permit before any development in a FEMA Special Flood Hazard Area or designated desert wash.

Hesperia FAQ
Do I need a Coastal Development Permit in Hesperia?
No. The California Coastal Act (Cal. Public Resources Code §30000 et seq.) only applies within the mapped coastal zone, which extends inland from the Pacific Ocean. Hesperia is roughly 85 miles inland in the Mojave Desert, entirely outside the coastal zone. Local development is governed by HMC Title 16 (Development Code) and CEQA where applicable.
Who handles environmental review for new development?
Discretionary development projects undergo California Environmental Quality Act (CEQA) review under Cal. Public Resources Code §21000 et seq., administered by the City of Hesperia as lead agency for most local projects. Federal review (NEPA) attaches where federal funding or permits are involved.
Rancho Cucamonga FAQ
Does San Bernardino County have coastal development rules?
No. San Bernardino County is entirely inland - the Mojave Desert, Inland Empire, and San Bernardino Mountains - with no Pacific coastline and no California Coastal Commission jurisdiction. The inland equivalent is FEMA-mandated floodplain regulation administered through the Floodplain Safety (FP) Overlay in Title 8 Chapter 82.14 of the County Development Code, with Public Works acting as the Floodplain Administrator under Section 86.04.010.
Do I need a permit to build near a desert wash or alluvial fan?
Almost certainly yes. Many washes and alluvial fans across San Bernardino County - including the Mojave River, Cajon Wash, Lytle Creek, and Yucaipa Creek - are mapped as Special Flood Hazard Areas on FEMA Flood Insurance Rate Maps and overlapped by the FP1 or FP2 overlay. Section 82.14.050 requires elevation certification, no increase in base flood elevation, and for floodway sites a HEC-RAS no-rise study by a registered civil engineer.
How high does my house have to be built in a Zone A or Zone AE area?
Per FEMA and County rules, a structure in Zone A must have its lowest floor at least 2 feet above the natural highest adjacent ground; in Zone AE the lowest floor must be at least 1 foot above the published base flood elevation; in Zone AO it must be at least 1 foot above the mapped shallow-flood depth. An Elevation Certificate is required, and Section 82.14.050 prohibits fill that increases base flood water-surface elevation.
