Census blockgroup geometry within Santa Clara County from the 2010 Census Tiger shapefiles. Feature class derived from Tiger line shapefile of 2010 census blockgroups 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.

A cadastral map is a map showing the boundaries of subdivisions of land. It is based on bearings, lengths and areas of individual tracts, for purposes of describing and recording ownership. Some areas on the cadastral map may also show topography, drainage, and other features relating to the value of the land and its uses. The cadastral map number is the first number used in the series of three numbers for determining the County Grid Number. The Cadastral Map layer is comprised of the County Cadastral Maps series that cover the entire County of Santa Clara. It contains 281 individual maps and numbered from west to east and from north to south. Cadastral Map No. 1 is in the northwest area of Santa Clara County. Each cadastral map covers approximately 150,000,000 square feet. The information on these maps were last updated about 1986-1988. A corner record is the means by which the re-establishment or rehabilitation of public land survey corners or other property corners may be made of record and brought to public attention.
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.
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.
