Title: Ventura County Important Farmland
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
Established in 1982, Government Code Section 65570 mandates FMMP to biennially report on the conversion of farmland and grazing land, and to provide maps and data to local government and the public.
Purpose:
The Farmland Mapping and Monitoring Program (FMMP) provides data to decision makers for use in planning for the present and future use of California's agricultural land resources. The data is a current inventory of agricultural resources. This data is for general planning purposes and has a minimum mapping unit of ten acres.

This data does not reflect general plan or zoning designations, city limit lines, changing economic or market conditions, or other factors which may be taken into consideration when land use policies are determined. This data is not designed to be used for parcel specific planning purposes due to its scale and the size of the minimum mapping unit (10 acres). The Department of Conservation makes no warranties as to the suitability of this data for any particular purpose.

Data_Quality_Information:
Logical_Consistency_Report:
The Important Farmland survey area is based on Natural Resources Conservation Service (NRCS) modern soil surveys covering most non-governmental lands in California; 49 counties are fully or partially surveyed at this time. Soil surveys specific to National Forests or other government land units are not surveyed. Beginning in 2000, SSURGO digital soil information was incorporated into the Ventura County Important Farmland data and the 2016 data began to incorporate the new NRCS Gridded Soil Survey (gSSURGO). Data subsequent to 2000 may have acreage and soil line differences due to incorporation of newer NRCS-SSURGO or gSSURGO editions.

Prior to the availability of SSURGO or gSSURGO, soil information was hand-transferred from the paper soil surveys. Older versions of the data have not been modified. The land use minimum mapping unit of ten acres has not changed, but digital soil units of less than one acre occur in the gSSURGO-enhanced Important Farmland data. The data between 2000 and 2014 incorporates SSURGO and the interaction of land use and soil components resulted in units of less than ten acres for categories such as Other Land (or Nonagricultural and Natural Vegetation). The 2016 data incorporates gSSURGO and will no longer merge resulting polygons less than one acre for any map category. For more information on gSSURGO, contact the USDA-Natural Resources Conservation Service: <https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/geo/?cid=nrcs142p2_053628>

County boundaries for the 2016 Important Farmland Series are from the California Department of Forestry and Fire Protection's Fire and Resource Assesment Program (FRAP) 2009 version of California Counties GIS data. <http://frap.fire.ca.gov/data/frapgisdata-sw-counties_download>

The non-surveyed area changed in 2008 due to adoption of updated county boundary file; this change was a net decrease of 1,316 acres. Adjacent counties gained or lost corresponding acreages. The non-surveyed area also increased in 2008 due to inclusion of California Channel Islands (+15,194 acres).

Definitions were developed by the USDA-NRCS as part of their nationwide Land Inventory and Monitoring (LIM) system.
Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: Prime Farmland (P)
Enumerated_Domain_Value_Definition:
Prime Farmland has the best combination of physical and chemical features able to sustain long-term agricultural production. This land has the soil quality, growing season, and moisture supply needed to produce sustained high yields. Land must have been used for irrigated agricultural production at some time during the four years prior to the mapping date.
Enumerated_Domain:
Enumerated_Domain_Value: Farmland of Statewide Importance (S)
Enumerated_Domain_Value_Definition:
Farmland of Statewide Importance is similar to Prime Farmland but with minor shortcomings, such as greater slopes or less ability to store soil moisture. Land must have been used for irrigated agricultural production at some time during the four years prior to the mapping date.
Enumerated_Domain:
Enumerated_Domain_Value: Unique Farmland (U)
Enumerated_Domain_Value_Definition:
Unique Farmland consists of lesser quality soils used for the production of the state's leading agricultural crops. This land is usually irrigated, but may include nonirrigated 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.
Enumerated_Domain:
Enumerated_Domain_Value: Farmland of Local Importance (L)
Enumerated_Domain_Value_Definition:
Soils that are listed as Prime or Statewide that are not irrigated, and soils growing dryland crops--beans, grain, dryland walnuts, or dryland apricots.
Enumerated_Domain:
Enumerated_Domain_Value: Grazing Land (G)
Enumerated_Domain_Value_Definition:
Grazing Land is land on which the existing vegetation is suited to the grazing of livestock.
Enumerated_Domain:
Enumerated_Domain_Value: Urban and Built-Up Land (D)
Enumerated_Domain_Value_Definition:
Urban and Built-up Land is 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. Common examples include residential, industrial, commercial, institutional facilities, cemeteries, airports, golf courses, sanitary landfills, sewage treatment, and water control structures.
Enumerated_Domain:
Enumerated_Domain_Value: Other Land (X)
Enumerated_Domain_Value_Definition:
Other Land is land not included in any other mapping category. Common examples include low density rural developments, brush, timber, wetland, and riparian areas not suitable for livestock grazing, confined livestock, poultry, or aquaculture facilities, strip mines, borrow pits, and water bodies smaller than 40 acres. Vacant and nonagricultural land surrounded on all sides by urban development and greater than 40 acres is mapped as Other Land.

Enumerated_Domain_Value_Definition:
Perennial water bodies with an extent of at least 40 acres.
Enumerated_Domain:
