The Williamson Act is a State program that preserves agricultural and other open space lands. In exchange for committing land to agricultural uses for at least 20 years, landowners receive significant tax breaks. In Sacramento County the Office of Planning and Environmental Review initiates and processes applications to establish Williamson Act land conservation agreements. The same department processes applications to "non-renew" agreements. The County Assessor's Office is responsible for calculating and assessing tax reductions related to the Williamson Act contracts.Agricultural Land Preservation

This layer represents parcels under active Williamson Act and Farmland Security Zone contracts. Tabular data for the basis of this layer was obtained from the Kern County Assessor's Office by way of the KQ12PO reports. These tables were joined to the 2025 parcel layer. This data represents parcels under active status for the year 2025, for which final reports were submitted to the State of California in January, 2025. A new layer is generated yearly. “The Williamson Act is a means to restrict the uses of agricultural and open space lands to farming and ranching uses during the length of the contract period. The Williamson Act Program was also envisioned as a way for local governments to integrate the protection of open space and agricultural resources into their overall strategies for planning urban growth patterns. To this end, three principal objectives were originally outlined:” Protection of Agricultural Resources, Preservation of Open Space Land, and Promotion of Efficient Urban Growth Patterns. “The Williamson Act Program enables local governments to enter into contracts with private landowners for the purpose of restricting specific parcels of land to agricultural or related open space use. Private land within locally-designated agricultural preserve areas is eligible for enrollment under contract. The minimum term for contracts is ten years. However, since the contract term automatically renews on each anniversary date of the contract, the actual term is essentially indefinite. Landowners receive substantially reduced property tax assessments in return for enrollment under Williamson Act contract. Property tax assessments of Williamson Act contracted land are based upon generated income as opposed to potential market value of the property. Local governments receive a partial subvention of forgone property tax revenues from the state via the Open Space Subvention Act of 1971. Contracts may be exited at the option of the landowner or local government by initiating the process of term nonrenewal. Under this process, the remaining contract term (nine years in the case of an original term of ten years) is allowed to lapse, with the contract null and void at the end of the term. During the nonrenewal process, the annual tax assessment continually increases each year until it is equivalent to current tax rates at the end of the nonrenewal period. Under a set of specifically defined circumstances, a contract may be cancelled without completing the process of term nonrenewal. Contract cancellation, however, involves a comprehensive review and approval process, and the payment of a fee by the landowner equal to 12.5 percent of the full market value of the property in question. Local activities such as eminent domain, or, in some rare cases city annexation, also result in the termination of Williamson Act contracts.”https://www.conservation.ca.gov/dlrp/lca/basic_contract_provisions More information about the California Land Conservation Act of 1965, Williamson Act - can be found by viewing Government Code, Title 5, Division 1, Part 1, Chapter 7, Section 51200 et. seq.
