What is an Alquist-Priolo Earthquake Fault Zone?
Alquist-Priolo Earthquake Fault Zones are regulatory zones that encompass surface traces of active faults that have a potential for future surface fault rupture. What does it mean to be located within an Earthquake Fault Zone? It means that an active fault is present within the zone and the fault may pose a risk of surface fault rupture to existing or future structures. If property is not developed, a fault study may be required before the parcel can be subdivided or before most structures can be permitted. If a property is developed, the Alquist-Priolo Act requires that all real estate transactions within an Earthquake Fault Zone be disclosed by the seller to prospective buyers.
