Natural Hazards in Los Angeles County
These are the hazard categories that most often drive disclosure answers in Los Angeles County. Each one is a separate determination on the Natural Hazard Disclosure Statement.
Alquist-Priolo Earthquake Fault Zones follow the San Andreas, Hollywood, Newport-Inglewood, Santa Monica, and Sierra Madre faults, cutting through dense residential neighborhoods from the Westside to the San Gabriel Valley.
Extensive state-mapped liquefaction zones run along the coastal plain, the Los Angeles River corridor, and the harbor area in Long Beach and Wilmington.
Very High Fire Hazard Severity Zones cover Malibu, the Santa Monica Mountains, Altadena and the foothill communities, and much of the Angeles National Forest interface.
FEMA Special Flood Hazard Areas appear along river and wash channels and in low-lying South Bay and Antelope Valley basins, plus dam inundation areas below reservoirs.
Decades of industrial, aerospace, and oilfield activity leave groundwater contamination plumes and Cortese List sites across the San Fernando Valley, the Gateway cities, and the Alameda corridor.
Property Taxes in Los Angeles County
Every property in Los Angeles 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 Los Angeles County to roughly 1.16%, so a bill is usually a little above 1% of what the buyer paid. Bond rates vary widely between cities, so two homes of equal value in different school districts can carry noticeably different bills. 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.
