The County of Santa Clara provides the services that hold the fabric of our society together. While cities in California primarily exist to protect property, counties exist to protect people and the community in which they live.

Earthquake Fault Rupture Zones are regulatory zones around active faults (USGS 2005). The zones are defined by turning points connected by straight lines. Fault rupture zones do not correspond with Alquist-Priolo fault zones.

The Alquist-Priolo Earthquake Fault Zones and fault traces as shown on the Official Alquist-Priolo Earthquake Fault Zones Map of the Santa Clara County. Alquist-Priolo fault zones do not correspond with fault rupture zones. The Alquist-Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of surface faulting to structures for human occupancy. This state law was a direct result of the 1971 San Fernando Earthquake, which was associated with extensive surface fault ruptures that damaged numerous homes, commercial buildings, and other structures. Surface rupture is the most easily avoidable seismic hazard. It directs the State of California Department of Conservation - Geological Survey to compile detailed maps of the surface traces of known active faults. The Alquist-Priolo Earthquake Fault Zoning Act's main purpose is to prevent the construction of buildings used for human occupancy on the surface trace of active faults. The 1:24,000-scale (24K) U.S. Geological Survey (USGS) quadrangle boundary data set contains the approximate boundaries of the various 24K USGS quadrangles and the names and indexing codes associated with each 24K quadrangle.

Major roads, which were subjectively determined, were selected and dissolved based upon name (including street prefix) and attributed with road number and road class. Multiple lane roads (i.e. multiple centerlines representing the travel direction or volume of a road) were dissolved to one line for generalization and labeling purposes. Primary criteria for inclusion; all freeways, highways, expressways, county routes, primary reference is: http://www.cahighways.org/. Additionally, major arterials and arterials were included, primary reference is local knowledge and criteria is to emphasize the mesh nature of roads within the county.
