The Washington County Planning and Parks Department has finalized the planning process for updating the Washington County Park and Open Space Plan. A seven member advisory commission, guiding the progress of the plan update, consists of representatives of local governments, the Wisconsin Department of Natural Resources, and the Metropolitan Builders Assn. On April 21st, 2020 the Park and Open Space Plan was approved by the Washington County Board of Supervisors.

The updated plan identifies long-term needs for park and open space acquisition and development and proposes recommendations to satisfy those needs extending to the year 2035. The past 2020 plan was adopted by the Washington County Board of Supervisors on March 9, 2004. The 2035 plan also allows the County to remain eligible to apply for State and Federal park grants.
