Description: On February 26, 2002 the Santa Clara Board of Supervisors officially adopted the County Geologic Hazards Zones (GHZ) and the revised ordinance. The GHZs were produced by combining information from a variety of published and unpublished sources regarding the location and extent of possible faults, landslides, compressible soils, dike failure flooding, and liquefaction. The County GHZs identify areas where available information suggests specific geologic hazards may be present. In those areas, the ordinance requires that the owner/applicant submit a geologic report (prepared and signed by a Certified Engineering Geologist [CEG]) for review by the County Geologist prior to approval of certain applications for construction.

When the Board adopted the County GHZs in 2002, the State Geologist had already released four official Seismic Hazard Zones Maps, the landslide and liquefaction zones on those maps were incorporated into the County GHZs. At that time, the Board of Supervisors also adopted a provision that the County GHZs would be revised to include California's Seismic Hazard Zones (SHZ) when ever the State Geologist released additional SHZ maps.
