    <abstract lang="eng" displayLabel="Abstract">This polygon shapefile depicts land parcels that are regulated under the Williamson Act. The California Land Conservation Act, better known as the Williamson Act, has been the California&#x2019;s agricultural land protection program since its enactmentin1965. The Williamson Act preserves agricultural and open space lands through property tax incentives and voluntary restrictive use contracts. Private landowners voluntarily restrict their land to agricultural and compatible open space uses under minimum ten year rolling term contracts with local governments. In return, restricted parcels are assessed for property tax purposes at a rate consistent with their actual use, rather than potential market value. The purpose of the Williamson Act is to preserve the County&#x2019;s prime soils and intensive high value agricultural operations, and to discourage premature and unnecessary conversion of agricultural land to urban use. This layer is part of a collection of GIS data for San Mateo County, California.</abstract>
