Riverside could take over county park Posted By: Ben Butler August 12, 2009 @ 4:58 am Today's Local News Tweet Share Email Riverside could be taking over a Washington County park. Conservation Director Steve Anderson says the city is in a better position to care for the park than the county is. He says the entire park is actually in the city limits. There will be a public hearing tonight (8/12) at 4:30 at the Marr Park Conservation Center on the proposal.
