Rialto FAQ
Do I need a Coastal Development Permit to build in Rialto?
No. The California Coastal Act and the Coastal Commission's permit jurisdiction apply only inside the Coastal Zone defined in PRC §30103. Rialto is roughly 60 miles inland and is entirely outside the Coastal Zone, so no CDP is ever required.
What replaces coastal review for Rialto projects?
Environmental review falls under CEQA (PRC §21000 et seq.) implemented by the city as lead agency, plus Rialto's grading, floodplain, stormwater, and zoning codes (Titles 13, 15, and 18).
Does the Coastal Commission have any authority over Rialto?
No. The Commission's jurisdiction is geographically limited to the Coastal Zone. Inland cities like Rialto are not subject to Coastal Act permitting or LCP requirements.
Victorville 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.
