- Garcia, Paul and Price, Matt
- This polygon shapefile represents fault zones for the County of Santa Cruz, California that are characterized by fractures in the Earth's crust. These zones of fracture are designated by the Seismic Safety Element of the General Plan/Local Coastal Plan and California State-designated Seismic Review Zones. Fault Zones designated for review by the County include the Butano, Sargent, Zayante and Corralitos complexes. State-designated Seismic Review Zones include the San Andreas and portions of the Zayante and Butano complexes. This layer is part of a collection of GIS data created for Santa Cruz County, California. The Geographic Information Systems (GIS) Unit falls under the purview of the County of Santa Cruz Information Services Department. The GIS Unit serves all County departments and external customers and provides data on land, features and people of Santa Cruz County. Santa Cruz County encompasses 4 cities and approximately 265,000 people. This coverage can be used for basic applications such as viewing, querying and map output production, or to provide a basemap to support graphical overlays and analyses of geospatial data.

New Information Acceptable for Updating Maps: General Plan amendment. Parcel Specific Overiding Information: Report by certified engineering geologist. Source maps boundaries were traced or transferred to USGS 7.5 minute quadrangle sheets. Boundaries were then digitized using known control points or intersections of roads for reference. For some sheets, as few as two known control points were available. The boundaries were plotted and reviewed by the County's Advanced Planning staff. These data were compiled from many different sources; therefore, the accuracy of the individual layers varies significantly, and some layers do not align exactly with others. In the urban areas, data are generally accurate within five to ten feet of their true geographic coordinates, but in the rural areas, data may be accurate to only within three hundred feet. With these limitations, the County of Santa Cruz disclaims any responsibility for the accuracy or correctness of this data. This disclaimer is exclusive and in lieu of any warranties, fitness for particular purpose, and/or any other type of warranty, whether expressed or implied.
