A community effort to keep Annadel State Park open that includes a $100,000 donation from philanthropist Henry Trione is expected to get a big boost today from Sonoma County's Board of Supervisors.
The board is expected to give county officials the authority to enter into a one-year agreement with the state allowing the county to take over operations of the popular 5,000-acre park in east Santa Rosa.
The deal, which requires approval from the California Department of Parks and Recreation, would keep Annadel open past a July 1 deadline when dozens of parks statewide are slated to close for budget reasons.
The agreement also would represent an unprecedented role for the county in state park management, one that Supervisor Valerie Brown, whose district includes Annadel, said could extend past June 2013, when the agreement is set to expire.
"I can't imagine the state gets in a better financial position to take it back," she said Monday.
Trione's $100,000 donation was made last July but only now is becoming public. He could not be reached for comment Monday.
Trione was instrumental in helping to acquire the property that would become Annadel State Park in 1972 and thwarting a massive development proposed on the property surrounding Lake Ilsanjo.
Trione put $300,000 to $400,000 into the Annadel deal, and purchased a 400-acre portion of the property that he developed into a polo field and the Wild Oak subdivision. His home is adjacent to the park.
County Regional Parks said it will cost $277,737 to operate Annadel for a year. The money has been raised through private donations and a one-time payment of $50,000 from state parks, which also has committed to retaining a supervising park ranger at Annadel, an in-kind value of $100,000.
The county's regional parks agency will manage Annadel as part of its adjacent Spring Lake Park operation.
