Figure S-2 Regional Earthquake Faults
ABOUT THE MAP. This map shows the approximate location and extent of well-known fault hazards and their proximity to Santa Ana. The areas around these faults are known as earthquake fault zones, and state law requires jurisdictions to carefully evaluate development proposals within these zones. Although no such fault zones are known to exist in Santa Ana, the City adheres to the California Building Code and evaluates geologic hazards as part of the permitting process.
