City boundaries.

Historically, the earliest Bakersfield “urban” subdivisions were not called tracts. The downtown area was subdivided into blocks and lots. Early citywide maps show the city blocks numbered from 1 to over 700. Some blocks were designated by letters rather than numbers. Each block was further subdivided into numbered lots. Thereafter housing subdivisions were called tracts and initially were named (example; Lowell Addition). Many of these “Named” tracts were also subdivided into blocks and lots. The earliest rural land subdivisions are the Sales Map Lands of J. B. Haggin and the Sales Map Lands of the Kern County l Land Company. The legal description of most modern lots is comprised of some combination of the fields: Document Type, Map Number, Phase and Lot Number. A “Block” field should be added for old parcels whose legal description is comprised of tract, block and lot (or just block and lot). The legal description fields for most of the older parcels are not populated at this time.

All COGO’d parcels are considered “Excellent” quality User Flag This field is for temporary data storage. However the following user flag values provide information about how the parcel features originally built or subsequently edited: CAD CONVERSION - parcels were developed from georeferenced CAD data. Quality is considered excellent. COGO - parcels were first developed employing COGO editing tools. Quality is considered excellent REBUILT - parcels were originally Valleywide GIS features that were rebuilt using COGO and other editing tools. Quality is considered excellent except parcels that were rebuilt where only assessor maps were available. SHIFTED - original parcels were considered geometrically adequate but required a slight positional shift. Whole blocks of contiguous lots were shifted together. Quality is considered good. Class(Domain)This field provides an opportunity to classify lots for specific purposes. The Private road lot class was created so these lots could be neglected when exporting parcels for the Community Maps Project. Landscape lot Private road lot School lot Sump lot Water Well lot Additional classes could be developed. For the vast majority of parcels the class field is not populated. Address The street address of a lot can be populated if the address point feature class objects have already been created and populated by the GIS Analyst at Community Development. Where there are multiple addresses on a parcel, this data is captured on the Address Point feature class. Assessor Parcel Number (APN) and Assessor Tax Numbers (ATN)The most important parcel layer attributes are the APN and ATN values that are assigned by the Kern County Assessor. An 8 digit APN is assigned to a property that has a specific geometry as defined by a legal description. If any new change occurs such as a lot line adjustment, then the geometry of the parcel(s) are changed and the APN’s for the affected properties are dropped and are never re-assigned. New unique APN’s are assigned to the affected properties and remain as long as the legal description of the geometry does not change. It usually takes at least a few months after a tract is recorded and the parcel feature class objects are developed before the County assigns APN’s to those parcels. The APN field is populated with “NEW” until such time as values are assigned. Parcel APNs can be acquired from the following sources: https://kernpublicworks.com/maps/parcel-maps/, Preliminary (January) and final (July) Kern County parcel GIS releases. Some Condominium common areas do not have an APN. The APN field is populated with “CONDOLOT”. These parcels are retained in order to preserve road right of ways. Compare City parcel layer features with County features to visualize why we retain these parcels.

The District boundary definitions are primarily based on the California county boundaries. The Board of Equalization (BOE) County and City Boundary web service is the authoritative source of County boundaries and this was used to digitize the district boundaries based on the data from March 2023. This data is solely for informational purposes. District 9 has been operating independent of the Central Region since November 1, 2015. Kern County remains the only split county in the state, between Districts 6 and 9 respectively. The BOE data was also used to create the district boundary layers along the coastline.

This shapefile contains tax rate area (TRA) boundaries in Kern County for the specified assessment roll year. Boundary alignment is based on the 2020 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

This data is intended to provide a reasonable representation of parcels, as defined for property tax assessment purposes, that can be used easily in a computerized geographic information system. This data is not intended to replace the hardcopy assessment maps or any other official or unofficial county maps, and it is not to be construed as portraying legal ownership or divisions of land for purposes of zoning or subdivision law.

This feature class contains "land" (surface rights) parcel boundaries delineated for property tax assessment purposes.

This feature class includes all private, tax-exempt, and state-assessed land parcels listed on the secured tax roll, but does not include mineral rights (subsurface) parcels, mobilehomes, or unsecured entities.

Parcels are modeled as planimetric polygons in a seamless fabric comprising the spatial extent of the County of Kern, in the State of California.

Tax Roll Data is available in separate database tables, which can be joined to the feature class using the APN9 field as the SQL join key.

These vector contour lines are derived from the 3D Elevation Program using automated and semi-automated processes. They were created to support 1:24,000-scale CONUS and Hawaii, 1:25,000-scale Alaska, and 1:20,000-scale Puerto Rico / US Virgin Island topographic map products, but are also published in this GIS vector format. Contour intervals are assigned by 7.5-minute quadrangle, so this vector dataset is not visually seamless across quadrangle boundaries. The vector lines have elevation attributes (in feet above mean sea level on NAVD88), but this dataset does not carry line symbols or annotation.Metadata Link for the USGS 1/3 arc-second Contour Downloadable Data Collectionhttps://www.sciencebase.gov/catalog/file/get/4f70ab22e4b058caae3f8deb?f=_disk_35%2F1e%2F20%2F351e2044b02ae4f163c2cdcaa66fda19a32a4ba4&transform=1&allowOpen=true

The project leads for the collection of this data were Julie Garcia and Evan King. Mule deer (32 adult females) from the Kern River herd were captured and equipped with Lotek LiteTrack Iridium collars, transmitting data from 2020-2021. GPS fixes were set for 2-hour intervals. The Kern River herd migrates from winter ranges in Sequoia National Forest north of Johnsondale and east of Slate Mountain northward to the area around Redrocks Meadows and along the Kern Canyon ridgeline to Sequoia National Park. Due to a high percentage of poor fixes, likely due to highly variable topographic terrain, between 2-18 percent of GPS locations per deer were fixed in 2-dimensional space and removed to ensure locational accuracy. The methodology used for this migration analysis allowed for the mapping of winter ranges and the identification of migration corridors and stopovers. Brownian Bridge Movement Models (BBMMs; Sawyer et al. 2009) were constructed with GPS collar data from 27 migrating deer, including 69 migration sequences, location, date, time, and average location error as inputs in Migration Mapper. The average migration time and average migration distance for deer was 15.38 days and 32.13 km, respectively. Corridors and stopovers were prioritized based on the number of animals moving through a particular area. Separate models using Brownian bridge movement models (BMMM) and fixed motion variances of 1000 were produced per migration sequence and compared for the entire dataset, with best models being combined prior to population-level analyses (10 percent of sequences selected with BMMM). Corridors were produced at a spatial resolution of 50 m using a sequential fix interval of less than 27 hours. Winter range analyses were based on data from 27 individual deer and 60 wintering sequences using a fixed motion variance of 1000. Winter range designations for this herd may expand with a larger sample, filling in some of the gaps between winter range polygons in the map. Additional migration routes and winter range areas likely exist beyond what was modeled in our output.Corridors are visualized based on deer use per cell in the BBMMs, with greater than or equal to 1 deer, greater than or equal to 3 deer (10 percent of the sample), and greater than or equal to 6 deer (20 percent of the sample) representing migration corridors, moderate use, and high use corridors, respectively. Stopovers were calculated as the top 10 percent of the population level utilization distribution during migrations and can be interpreted as high use areas. Stopover polygon areas less than 20,000 m2 were removed, but remaining small stopovers may be interpreted as short-term resting sites, likely based on a small concentration of points from an individual animal. Winter range is visualized as the 50th percentile contour of the winter range utilization distribution.

Pursuant to Section 51237 of the State of California Government Code, agricultural preserve boundaries are filed and kept current by the Planning and Natural Resources Department.This layer contains the boundaries for the agricultural preserves for the County of Kern. "An agricultural preserve defines the boundary of an area within which a city or county will enter into contracts with landowners. The boundary is designated by resolution of the board of supervisors (board) or city council (council) having jurisdiction. Only land located within an agricultural preserve is eligible for a Williamson Act contract. Preserves are regulated by rules and restrictions designated in the resolution to ensure that the land within the preserve is maintained for agricultural or open space use (California Dept. of Conservation)."This should be used with the "agricultural preserve included" layer to determine what property is eligible for a Williamson Act contract.

This digital dataset contains historical geochemical and other information for 100 samples of groundwater from 71 wells located within 3 miles of the Poso Creek Oil Field in Kern County, California. An additional 12 wells in the Poso Creek study area, but co-located within 3 miles of the adjacent Rosedale and Rosedale Ranch Oil Fields, were not included in this data release; these data are planned for a future data release associated with those fields. The sampled wells include water-supply wells used primarily for domestic, irrigation, and industrial uses. Numerical water chemistry data were compiled from two data sources: 1) Kern County Public Health Services Department (KCPHSD) PDF (Portable Document Format) files, and 2) the Eastside Water Management Area (EWMA) Groundwater Sustainability Plan (GSP) Chapter. These data sources include varying location and well-construction information. Locations for most of the wells represent either well-specific coordinates provided in the KCPHSD PDFs, approximate locations determined using ArcGIS (GIS, Geographic Information System) software based on descriptive information or location maps in the KCPHSD PDFs, parcel centroid coordinates determined from a GIS parcel shapefile (KERN PARCEL) based on parcel numbers provided by either the KCPHSD or EWMA data source, or approximate locations from Google Earth based on visual identification of well locations. For two wells (Dataset_IDs 1 and 2) coordinates represent the locations provided by the California Department of Water Resources Water Data Library (CDWR WDL) as those particular wells are located in that database in association with water-level measurement data. For three wells (Dataset_IDs 22, 30, and 42) having limited information, locations represent meridian, township, range, section, and quarter-quarter section (MTRSQQ) centroids. Information on well construction was compiled from California Department of Water Resources Well Completion Reports (CDWR-WCR) included with the PDFs located on the KCPHSD website, or located on the CDWR Well Completion Reports Map Application website. Well construction from CDWR-WCRs was available for 53 of the 71 wells. For one well (Dataset_ID 5), a WCR could not be located, however, well construction information was available in the EWMA GSP. Data were manually compiled into two separate files described as follows: 1) a summary data file that includes well identifiers, location, construction, the number of chemistry samples, the period of record, specific sample dates for each site, and an inventory of which constituent groups were sampled on each date; and 2) a data file of geochemistry analyses for selected constituents classified into one of the following groups: water-quality indicators, major and minor ions, nutrients, trace elements, naturally occurring radioactive material (NORM), and volatile organic compounds (VOCs). Ion (charge) balance calculations and percent error of these calculations were included for samples having a complete suite of major ion analyses. Parameter code, analytical method, reporting level, reporting level type, and supplemental notes were included where available or pertinent. A data dictionary was created to describe the geochemistry data file and is provided with this data release.
