The POI Dataset is a digital representation of the physical, geographic and commercial features across all of Santa Clara County. This dataset aims to provide accurate location information in the map. Sources: California Department Of Education (2016), Santa Clara County Combined data (2016).
Census block geometry within Santa Clara County from the 2010 Census Tiger shapefiles. Feature class derived from Tiger line shapefile of 2010 census blocks for Santa Clara County and geographic identifier table, G001. Some attribute names may be when exporting as shapefile due to 10 character limitation of shapefile attribute names.
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.
