(Technical definitions for these map categories can be found in "A Guide for the Farmland Mapping and Monitoring Program".) IMPORTANT FARMLAND MAP CATEGORIES Important Farmland maps for California are compiled using USDA-NRCS Soil Surveys and current land use information using eight mapping categories generally explained below. The minimum mapping unit is 10 acres. Units of land smaller than 10 acres are incorporated into the surrounding map categories. Prime Farmland (P) Irrigated land with the best combination of physical and chemical features able to sustain long term production of agricultural crops. This land has the soil quality, growing season, and moisture supply needed to produce sustained high yields. Land must have been used for production of irrigated crops at some time during the four years prior to the mapping date. Farmland of Statewide Importance (S) Irrigated land similar to Prime Farmland that has a good combination of physical and chemical characteristics for the production of agricultural crops. This land has minor shortcomings, such as greater slopes or less ability to store soil moisture than Prime Farmland. Land must have been used for production of irrigated crops at some time during the four years prior to the mapping date. Unique Farmland (U) Lesser quality soils used for the production of the state's leading agricultural crops. This land is usually irrigated, but may include non-irrigated orchards or vineyards as found in some climatic zones in California. Land must have been cropped at some time during the four years prior to the mapping date. Farmland of Local Importance (L and LP) Land of importance to the local agricultural economy as determined by each county's board of supervisors and a local advisory committee. See either "A Guide to the Farmland Mapping and Monitoring Program", or the latest copy of the "Farmland Conversion Report" for each county's definition of Farmland of Local Importance. Grazing Land (G) Land on which the existing vegetation is suited to the grazing of livestock. This category is used only in California and was developed in cooperation with the California Cattlemen's Association, University of California Cooperative Extension, and other groups interested in the extent of grazing activities. The minimum mapping unit for Grazing Land is 40 acres. Urban and Built Up Land (D) Land occupied by structures with a building density of at least 1 unit to 1.5 acres, or approximately 6 structures to a 10-acre parcel. Other Land (X) Land which does not meet the criteria of any other category. Typical uses include low density rural development, heavily forested land, mined land, or government land with restrictions on use. Water (W) Water areas with an extent of at least 40 acres. Area Not Mapped (Z) Area which falls outside of the NRCS soil survey. Not mapped by the FMMP. INTERIM FARMLAND MAP CATEGORIES Interim Farmland maps are prepared for specific agricultural counties lacking modern soil surveys. Two categories of Interim Farmland are mapped in lieu of Prime Farmland, Farmland of Statewide Importance, Unique Farmland, and Farmland of Local Importance. The categories of Irrigated Farmland and Non-Irrigated Farmland are designed to be easily upgraded as the USDA-NRCS completes modern soil survey mapping as the technical soil information becomes available. The Interim Farmland maps also utilize the categories of Grazing Land, Urban and Built-up Land, Other Land, and Water as defined under the section 'Important Farmland Map Categories'. Irrigated Farmland (I) Cropped land with a developed irrigation water supply that is dependable and of adequate quality. Land must have been used for production of irrigated crops at some time during the four years prior to the mapping date. Non-irrigated Farmland (N) Land on which agricultural commodities are produced on a continuing or cyclic basis utilizing stored soil moisture. DRAFT MAP CATEGORIES Early versions of maps may have the categories of iP and nG, which are mixed irrigated pasture and dry grain, respectively. These land uses are often incorporated into the Farmland of Local Importance definitions for counties once the initial map has undergone review by a Local Advisory Committee and the County Board of Supervisors. _________________________________ VITAL STATISTICS Projection: Albers Equal Area Datum: NAD 27 Ellipsoid: Clarke 1866 Longitude of Origin: -120:00:00 Latitude of Origin: 0:00:00 Standard Parallel 1: 34:00:00 Standard Parallel 2: 40:30:00 False Easting: 0.00 meters False Northing: -4000000.000 meters Working Units (DGN format): 1,000 UORs per meter Storage Center Point (DGN format): X: 0.00 meters, Y: 0.00 meters Source: California Department of Conservation Farmland Mapping and Monitoring Program Source Media: Aerial photographs of various scale (Mostly 1:130,000 scale CIR) and field reconnaissance.

DATA QUALITY ASSESSMENT The following are subjective comments regarding this data. The extent of the farmland coverage corresponds to the availability of what the National Resources Conservation Service (NRCS) considers "modern soil surveys". Thus, coverage is so far limited to 48 of California's 58 counties. Some of these 48 counties have only been partially mapped as the NRCS has limited its efforts to areas which are agriculturally important. The soil surveys rarely extend into National Forests. Statistical note: Text files associated with this site that provide acreage figures for quality assurance purposes more accurately affect the files on the ftp site than the figures in older Farmland Conversion Reports. Changes made to files (projection change, standardized county line file, ellipsoidal calculations) since the publication of the Conversion Reports are not reflected in the published documents.

Agricultural land is rated according to soil quality and irrigation status; the best quality land is called Prime Farmland. The maps are updated every two years with the use of aerial photographs, a computer mapping system, public review, and field reconnaissance Kern County Agricultural areas including grazing land, prime and unique farmland, irrigated farmland, farmland of statewide importance, farmland of local importance, urban and built up areas. Data was collected from aerial photographs of various scale (Mostly 1:130,000 scale CIR) and field reconnaissance.To aid local developers and planners.GENERAL DESCRIPTION The FMMP compiles two kinds of land use maps: Important Farmland Maps for those areas that have modern soil surveys, and Interim Farmland Maps for those areas lacking modern soil survey information and for which there is expressed local concern on the status of farmland.
