This dataset contains Tract Map boundaries within the County of Kern. Updated 4-29-2025

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 APN field as a key.

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.

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.

This feature class contains "Mineral Rights" (subsurface) parcel boundaries which are assessed separately from the land (surface) parcels.This feature class includes all mineral rights parcels listed on the mineral tax roll, but does not include land (surface) parcels, mobilehomes, or unsecured entities.Mineral parcels are further categorized as either "producing" or "non-producing". While all producing mineral parcels are assessed, non-producing mineral parcels are assessed only if they have an "indication of value", such as those purchased or leased for the purpose of exploration. Mineral parcels having no indication of value are not assessed, and therefore are not mapped, maintained, or otherwise tracked by the Assessor in this (or any other) dataset.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 APN field as a key.

This map shows how each census tract measures with respect to both solar potential and household solar usage.Out of the top 20 census tracts that have a high and consistent potential for solar, yet have low current usage rates, 11 of them were in the Victorville/Hesperia area of San Bernardino County, California. Another seven tracts were on the border of Los Angeles and Kern counties, spanning the cities of Lancaster, Mojave, and California City. The top tract is in the Yucca Valley area. These are places that might benefit from some incentive programs that offset or spread out the initial investment.Other related items:ArcGIS blog article explaining our processaccompanying feature layer to this web map (also referenced below)"Top 20" Geolist appSources: U.S. Census Bureau's American Community Survey (ACS) 2014-2018 5-year estimates, Table(s) B25040, B25117, as well as Esri analysis of data obtained from the “Global Solar Atlas 2.0", a free, web-based application is developed and operated by the company Solargis s.r.o. on behalf of the World Bank Group, utilizing Solargis data, with funding provided by the Energy Sector Management Assistance Program (ESMAP).
