Reports and Statistics

Data and Maps

A Williamson Act contract is entered into by the landowner and the participating city or county. Current enrollment and contract information is held by the city or county offering the contract. For the most current and up to date information on the status of Williamson Act contracted parcels the Department suggests that interested parties contact the ​city or county in which the property resides.

California Williamson Act Enrollment Finder

T​he recent passage of Senate Bill 574 has simplified Williamson Act reporting requirements. Enrollment information is now collected in Geographic Information System form, and is made available through the California Williamson Act Enrollment Finder.​

Biennial Williamson Act Status Reports

Until 2022, Government Code Section 51207 required biennial status reports on Williamson Act enrollment. The reports provided statistical insights based on county and city data and were published in even-numbered years. These reports remain avaliable below or via email at: LCA@conservation.ca.gov.

Following the enactment of Senate Bill 574​ in 2022, Government Code section 51207 was revised to streamline the reporting of statistics and to share figures on the Department's website every even-numbered year. These figures will continue to be​ posted on this webpage biennially and are available below beginning in the 2024 reporting year.
