City of San Leandro <br />14143-14273 Washington Avenue Warehouse Project <br /> <br />22 <br />Regulatory Setting <br />The DOC’s Farmland Mapping and Monitoring Program (FMMP) monitors the conversion of the <br />State’s farmland to and from agricultural use. County-level data is collected, and a series of maps <br />are prepared that identify eight classifications and uses based on a minimum mapping unit size of 10 <br />acres. The program also produces a biennial report on the amount of land converted from <br />agricultural to non-agricultural use. The program maintains an inventory of State agricultural land <br />and updates the Important Farmland Series Maps every two years. The FMMP is an informational <br />service only and does not constitute State regulation of local land use decisions. Agricultural land is <br />rated according to several variables, including soil quality and irrigation status with Prime Farmland <br />being considered the most optimal for farming practices. Other FMMP designations include <br />Farmland of Local Importance, Grazing Land, and Water. <br />Land Conservation Act <br />Better known as the “Williamson Act” (California Administrative Code Section 51200 et seq.), the <br />California Land Conservation Act of 1965 creates a legal arrangement whereby private landowners’ <br />contract with local governments to voluntarily restrict land to agricultural and open space uses, <br />protecting it from unnecessary or premature conversion to urban uses. In return, restricted parcels <br />are assessed for property tax purposes at a rate consistent with their actual use rather than <br />potential market value, which saves landowners from 20 percent to 75 percent in property tax <br />liability each year. <br />Generally, Williamson Act contracts have an initial term of ten years, with renewal occurring <br />automatically each year thereafter. The contracts run with the land and are binding on all <br />succeeding landowners. Land must be in an agricultural preserve to enter into a Williamson Act <br />contract. Agricultural preserves under Williamson Act contract contain at least 100 contiguous acres <br />of agricultural land unless specific findings are made. <br />Non-renewal initiations are requested either by the landowner or the local government and are <br />often filed in anticipation of converting farmland to other uses. Most contracted land is terminated <br />through non-renewal. Upon the expiration of the contract, the restrictions are removed and the <br />property tax assessment, which had been gradually increasing over the previous nine-year non- <br />renewal period, returns to full market value. <br />To characterize the environmental baseline for agricultural resources, Important Farmland Maps <br />produced by the DOC were reviewed. Unless otherwise expressed, the future use of “Important <br />Farmland” specifically includes the following definitions provided by the DOC: <br />▪ Prime Farmland: Land which has the best combination of physical and chemical characteristics <br />for producing crops. It has the soil quality, growing season, and moisture supply needed to <br />produce sustained high yields of crops when treated and managed, including water <br />management, according to current farming standards. <br />▪ Unique Farmland: Land of lesser quality soils used for the production of specific high economic <br />value crops. It has the special combination of soil quality, location, growing season and moisture <br />supply needed to produce sustained high quality or high yields of a specific crop when treated <br />and managed according to current farming methods. It is usually irrigated but may include non- <br />irrigated orchards or vineyards as found in some climatic zones in California. Examples of crops <br />include oranges, olives, avocados, rice, grapes and cut flowers.
