Natural Hazards in San Bernardino County
These are the hazard categories that most often drive disclosure answers in San Bernardino County. Each one is a separate determination on the Natural Hazard Disclosure Statement.
The San Andreas Fault runs through the Cajon Pass and along the base of the San Bernardino Mountains, with Alquist-Priolo zones through developed valley communities.
Shallow groundwater in the San Bernardino and Chino basins produces some of Southern California's most extensive mapped liquefaction zones.
Very High zones cover the mountain communities — Big Bear, Lake Arrowhead, Crestline, Running Springs — and the foothill interface.
FEMA flood areas follow the Santa Ana River, Mojave River, and desert washes, plus dam inundation zones below Seven Oaks and Big Bear.
Former defense, rail, and manufacturing operations leave documented groundwater plumes, including well-known perchlorate contamination in the Rialto-Colton basin.
Property Taxes in San Bernardino County
Every property in San Bernardino County starts from the Proposition 13 base rate of 1% of assessed value, using the purchase price as the base year value and rising by no more than 2% per year. Voter-approved bonds for schools, water, and infrastructure push the typical effective rate in San Bernardino County to roughly 1.15%, so a bill is usually a little above 1% of what the buyer paid. Newer developments in Fontana, Rancho Cucamonga, Victorville, and Hesperia often include Mello-Roos or landscape and lighting district assessments. Special assessments are layered on top of the ad valorem rate: Mello-Roos community facilities district taxes in newer subdivisions, 1915 Act bond assessments, and small district charges for lighting, vector control, or sewer service. Those line items are fixed dollar amounts rather than percentages, so they matter most on lower-priced homes. Supplemental tax bills arrive after a sale or new construction to reconcile the new assessed value with the prior owner's.
