Williamson Act

Status of the Act


On July 25, 2000, pursuant to the state Williamson Act, the Board of Supervisors adopted Local Rules of Procedures, a Fee Schedule Policy, a Contract Template and established an Agricultural Preserve boundary, thereby creating a local voluntary, differential tax assessment program to preserve agricultural lands.

On August 18, 2009, the Board determined that it would not accept any new land under Williamson Act Contract as a result of state action to halt tax reimbursement (subvention) payments to the County.

As a result, MERCED COUNTY IS NOT CURRENTLY ACCEPTING APPLICATIONS TO PLACE NEW LAND UNDER WILLIAMSON ACT CONTRACT. This action may be rescinded by the Board of Supervisors at such time the state determines to again provide subvention payments to the County, or should the Board determine they wish revisit their policy.
