In July 2000, the Merced County Board of Supervisors enacted the Williamson Act in Merced County. A property owner may enter into a 10-year contract and receive a guaranteed 5% reduction for prime land and trees or vines or a 5% reduction for non-prime land.
In many instances, the reduction may be greater. The contracts are automatically renewed each year unless you enter into non-renewal. Parcels as small as 10 acres may go into a contract if it is prime and meets the minimum qualifications. Non-prime properties must be at least 80 acres.
