Chino FAQ
Do I need a Coastal Development Permit to build in Chino?
No. Chino is not in the California Coastal Zone defined by Public Resources Code §30103. The California Coastal Act and Coastal Commission have no jurisdiction over Chino property — projects are reviewed under city zoning, building, and subdivision codes plus CEQA.
Why is there no coastal rule in Chino?
Chino is roughly 40 miles inland from the Pacific in San Bernardino County's Inland Empire. The Coastal Zone extends only ~1,000 yards inland from mean high tide (up to 5 miles in some areas). Chino is far outside that boundary.
What environmental review applies to large Chino projects?
The California Environmental Quality Act (CEQA, PRC §21000 et seq.) applies to all discretionary projects in California. Chino projects also need WQMP/SWPPP compliance (stormwater), CBC Appendix J (grading), and Title 20 zoning review — but no Coastal Act review.
Do Chino's actions affect the coast?
Indirectly yes. Chino sits in the upper Santa Ana River watershed — stormwater runoff eventually reaches the Pacific via the Santa Ana River through Orange County. That's why the MS4 stormwater permit (Order R8-2010-0036) requires Chino to control pollutant discharges, even though the city itself is inland.
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.
