This dataset includes one file for each of the 51 counties that were collected, as well as a CA_Merged file with the parcels merged into a single file.Note – this data does not include attributes beyond the parcel ID number (PARNO) – that will be provided when available, most likely by the state of California.DownloadA 1.6 GB zipped file geodatabase is available for download - click here.DescriptionA geodatabase with parcel boundaries for 51 (out of 58) counties in the State of California. The original target was to collect data for the close of the 2013 fiscal year. As the collection progressed, it became clear that holding to that time standard was not practical. Out of expediency, the date requirement was relaxed, and the currently available dataset was collected for a majority of the counties. Most of these were distributed with minimal metadata.The table “ParcelInfo” includes the data that the data came into our possession, and our best estimate of the last time the parcel dataset was updated by the original source. Data sets listed as “Downloaded from” were downloaded from a publicly accessible web or FTP site from the county. Other data sets were provided directly to us by the county, though many of them may also be available for direct download. Â These data have been reprojected to California Albers NAD84, but have not been checked for topology, or aligned to county boundaries in any way. Tulare County’s dataset arrived with an undefined projection and was identified as being California State Plane NAD83 (US Feet) and was assigned by ICE as that projection prior to reprojection. Kings County’s dataset was delivered as individual shapefiles for each of the 50 assessor’s books maintained at the county. These were merged to a single feature class prior to importing to the database.The attribute tables were standardized and truncated to include only a PARNO (APN). The format of these fields has been left identical to the original dataset. The Data Interoperablity Extension ETL tool used in this process is included in the zip file. Where provided by the original data sources, metadata for the original data has been maintained. Please note that the attribute table structure changes were made at ICE, UC Davis, not at the original data sources.Parcel Source InformationCountyDateCollecDateCurrenNotesAlameda4/8/20142/13/2014Download from Alamenda CountyAlpine4/22/20141/26/2012Alpine County PlanningAmador5/21/20145/14/2014Amador County Transportation CommissionButte2/24/20141/6/2014Butte County Association of GovernmentsCalaveras5/13/2014Download from Calaveras County, exact date unknown, labelled 2013Contra Costa4/4/20144/4/2014Contra Costa Assessor’s OfficeDel Norte5/13/20145/8/2014Download from Del Norte CountyEl Dorado4/4/20144/3/2014El Dorado County AssessorFresno4/4/20144/4/2014Fresno County AssessorGlenn4/4/201410/13/2013Glenn County Public WorksHumboldt6/3/20144/25/2014Humbodt County AssessorImperial8/4/20147/18/2014Imperial County AssessorKern3/26/20143/16/2014Kern County AssessorKings4/21/20144/14/2014Kings CountyLake7/15/20147/19/2013Lake CountyLassen7/24/20147/24/2014Lassen CountyLos Angeles10/22/201410/9/2014Los Angeles CountyMadera7/28/2014Madera County, Date Current unclear likely 7/2014Marin5/13/20145/1/2014Marin County AssessorMendocino4/21/20143/27/2014Mendocino CountyMerced7/15/20141/16/2014Merced CountyMono4/7/20144/7/2014Mono CountyMonterey5/13/201410/31/2013Download from Monterey CountyNapa4/22/20144/22/2014Napa CountyNevada10/29/201410/26/2014Download from Nevada CountyOrange3/18/20143/18/2014Download from Orange CountyPlacer7/2/20147/2/2014Placer CountyRiverside3/17/20141/6/2014Download from Riverside CountySacramento4/2/20143/12/2014Sacramento CountySan Benito5/12/20144/30/2014San Benito CountySan Bernardino2/12/20142/12/2014Download from San Bernardino CountySan Diego4/18/20144/18/2014San Diego CountySan Francisco5/23/20145/23/2014Download from San Francisco CountySan Joaquin10/13/20147/1/2013San Joaquin County Fiscal year close dataSan Mateo2/12/20142/12/2014San Mateo CountySanta Barbara4/22/20149/17/2013Santa Barbara CountySanta Clara9/5/20143/24/2014Santa Clara County, Required a PRA requestSanta Cruz2/13/201411/13/2014Download from Santa Cruz CountyShasta4/23/20141/6/2014Download from Shasta CountySierra7/15/20141/20/2014Sierra CountySolano4/24/2014Download from Solano Couty, Boundaries appear to be from 2013Sonoma5/19/20144/3/2014Download from Sonoma CountyStanislaus4/23/20141/22/2014Download from Stanislaus CountySutter11/5/201410/14/2014Download from Sutter CountyTehama1/16/201512/9/2014Tehama CountyTrinity12/8/20141/20/2010Download from Trinity County, Note age of data 2010Tulare7/1/20146/24/2014Tulare CountyTuolumne5/13/201410/9/2013Download from Tuolumne CountyVentura11/4/20146/18/2014Download from Ventura CountyYolo11/4/20149/10/2014Download from Yolo CountyYuba11/12/201412/17/2013Download from Yuba County

This shapefile contains tax rate area (TRA) boundaries in Santa Cruz County for the specified assessment roll year. Boundary alignment is based on the 2022 county parcel map. A tax rate area (TRA) is a geographic area within the jurisdiction of a unique combination of cities, schools, and revenue districts that utilize the regular city or county assessment roll, per Government Code 54900. Each TRA is assigned a six-digit numeric identifier, referred to as a TRA number. TRA = tax rate area number

The purpose of the Santa Clara County Interactive Map Viewer is to provide to all citizens of Santa Clara County an easy graphical means to locate places in the County, and to access information about those locations.

The Map Books consist of approximately 5,900 maps recorded with the county dating from circa 1850 to 1957. Recorded documents include subdivisions, surveys of property, cemetery plans, and other maps. Information on each map includes date recorded, person recorded for, and title of survey. Additional information may include notarized statement by property owner, statement by licensed surveyor, notice of approval by board of supervisors, and additional approvals by county or city officials. These maps are bound into 108 volumes. The archives have volumes A through Z, and volumes 1 through 82. Volumes not included are 44, 46, 48, 50, 51, 53, 55, 57, 59, 66, 68, 71, 73, 76, and 81.

This layer was created as an update the existing San Jose Parks Layer (PRK.PARKS). The existing layer has been maintained by the City of San Jose Department of Public Works and had not been updated in some time. This layer is a draft as of (05.02.2014) and has not been fully reviewed to assure complete accuracy of boundaries. Nevertheless it is an improvement over the existing layer and has had park boundaries adjusted to reflect PRNS management authority to the curb and gutter. This layer is also primarily based upon satellite imagery and visible property lines with the Santa Clara County parcel layer used as a guide in certain circumstances where boundaries could not be identified. The PRK.PARKS layer on the other hand , appeared to be based upon the Santa Clara Parcel layer, which did not include sidewalk and curb areas of the parks. In addition many parcel maps features included sections of roadway or overlapped into neighboring properties when compared with the aerial. Park chains have yet to be reviewed and revised. It is our intent to adjust these features to show only secured or quasi-government lands in which development in unlikely to occur. In addition, park chain lands may be adjusted to reflect underpasses where trails and public access is permitted.

Detailed Dataset Description: The impervious map was created using “expert systems” rulesets developed in Trimble Ecognition. These rulesets combine automated image segmentation with-object based image classification techniques. In contrast with machine learning approaches, expert systems rulesets are developed heuristically based on the knowledge of experienced image analysts. Key data sets used in the expert systems rulesets for impervious mapping included: high resolution (6 inch or greater) 4-band orthophotography (2020), the lidar point cloud (2020), and lidar derived rasters such as the canopy height model. After it was produced using Trimble Ecognition, the preliminary impervious map product was manually edited by a team of UVM’s photo interpreters. Manual editing corrected errors where the automated methods produced incorrect results. The impervious map has 5 classes, which are described below:

Building – Structures including homes, commercial buildings, outbuildings, and other human-made structures such as water tanks and silage silos. Structures fully occluded by vegetation will not be mapped.




Paved Road – Roads that are paved and wide enough for a vehicle.




Dirt/Gravel Road – Dirt or gravel roads wide enough for a vehicle. Non-ephemeral fire roads, ranch roads and long driveways. Polygons representing narrow unpaved (single track) trails are not included in this data product.




Other Dirt/Gravel Surface – Dirt or gravel surfaces that are highly compacted and used by humans and equipment, such as parking lots, road pull-offs, some dirt or gravel paths, and highly compacted areas around commercial activities. This class DOES NOT include natural turf playing fields, very lightly used dirt roads, livestock areas, naturally occurring bare soil or rock, or bare areas around ponds.




Other Paved Surface – Includes parking lots, sidewalks, paved walking paths, swimming pools, tennis courts.

Miscellaneous quality control and processing notes:

Zoom level used during manual quality control was no finer than 1 to 500.


Vector data was created with no overlapping polygons.

Data Limitations: This is not a planimetric data product and was created using semi-automated techniques. It provides a reasonable and useful depiction of impervious surfaces for planner and managers but does not have the accuracy or precision to support engineering. Please note that this dataset does not contain information about ownership potential access restrictions. Appropriate uses of the data product include:

As an input to storm water models




For planners to assess % imperviousness in a parcel/watershed




To help identify areas of human infrastructure for fuels and fire management




As an input to fuel models that are used in fire behavior and fire spread models




For cartography and mapping




Generally for use at scales 1:1,000 and smaller




Inappropriate uses of this product include:




Measuring exact square footage of structures or impervious features for building projects




Using the impervious as geographically precise information in transportation and public works




Determining ownership or maintenance responsibility of a particular feature, such as a paved or dirt road




Identifying publicly accessible areas for recreation or other uses

Confirming the suitability of a surface for any use including driving, hiking, bicycling, etc.

The Barrio de Tubac, Santa Cruz County, Arizona, is an archaeological preserve owned and managed by The Archaeological Conservancy (TAC). The Tubac settlement and townsite are included in the National Register of Historic Places. The Barrio de Tubac is eligible for inclusion in the National Register of Historic Places and a nomination form is being prepared.

On February 27 and 28, 2002, Steve Koczan from TAC and Barbara Ruppman and Philip Halpenny from the Tubac Historical Society completed the intensive site survey, feature documentation, and cultural resources map update at Barrio de Tubac (Project No. 64005). Then on April 20 and 21, 2002, the stabilization project was completed. TAC and Tubac Historical Society personnel were assisted by the Southwest Archaeology Team, Jerry Howard from the Mesa Southwest Museum, and Tubac Presidio State Historic Park. Mechanical equipment and support was provided by Dennis Jex; Collins Excavating, Inc.; and 4-Hire Contracting, Inc.

The purpose of the site survey and cultural resources map update is to provide a review of the Barrio de Tubac; to determine the nature, extent, and state of the cultural resources located within the preserve; and to provide a new map of the site that reflects the survey results and current conditions of the resource. The purpose of the stabilization is to identify previously excavated areas in the Barrio de Tubac, to document features at these locations, and to stabilize the locations where cultural material is exposed and deteriorating. The excavations were conducted by The Center for Spanish Colonial Archaeology before TAC acquired the property. The site survey, feature documentation, cultural resources map update, and stabilization have been completed in accordance with the commitments included in the FY 2000 Historic Preservation Certified Grant Application. This project was financed in part by a grant from the Historic Preservation Heritage Fund which is funded by the Arizona Lottery and administered by the Arizona State Parks Board.

High fire hazard area in Santa Cruz County, California. Within this area, new structures, room additions, and re-roofs require 'Class A' roofs as defined in the County's Unified Building Code. This area is delineated by five roads: Jamison Creek Rd, Highway 236, Highway 9, Alba Rd, and Empire Grade. Boundaries are occasionally adjusted to maintain coincidence with the County's Assessor's parcel boundaries. Contact the Santa Cruz County Planning Department for more information.

This shapefile contains tax rate area (TRA) boundaries in Santa Clara County for the specified assessment roll year. Boundary alignment is based on the 2012 county parcel map. A tax rate area (TRA) is a geographic area within the jurisdiction of a unique combination of cities, schools, and revenue districts that utilize the regular city or county assessment roll, per Government Code 54900. Each TRA is assigned a six-digit numeric identifier, referred to as a TRA number. TRA = tax rate area number

The debris flow polygons shown on this map show areas within and downslope of the CZU Lightning Complex Fire Burn Area where habitable structures may be impacted in the event of a debris flow. This map is not intended to be fully comprehensive or conclusive, but rather to serve as a tool to assist the Santa Cruz County Offices of Emergency Management, County Sheriff’s office, local Fire Protection Districts, local first responders, Santa Cruz County Department of Public Works, Caltrans, water districts, utility companies, and other responsible agencies in the development of more detailed post-fire emergency response plans. This information represents a combination of State-identified “Values at Risk” (VARs) listed in the Watershed Emergency Response Team (WERT) Report, as well as County identified VARs based on site specific field mapping and Geographic Information Systems (GIS) analysis conducted by Santa Cruz County geologic staff. This map is not intended to make any representation, express or implied, regarding the risk level of individual home sites. Any home downslope of a burned area should be assumed to be at elevated risk of debris flows and landslides. All property owners within or downslope of the CZU Fire Burn Area are encouraged to consult with a professional geologist to determine the risk of their structure being impacted by debris flows or other land movement. The path of a debris flow is unpredictable and may differ from that assumed in the evaluations upon which this map is based. Areas outside the debris flow polygons may be inundated; some properties not inundated may be cut off from emergency response personnel due to debris flows blocking roadways.
