Riverdale Regional Park and Fairgrounds Master Plan

The Adams County Parks & Open Space Department and a consultant team led by Design Workshop are working together to update the Adams County Regional Park and Fairgrounds Master Plan. The park serves as a respite for people, contains an abundance of wildlife, provides a variety of recreational opportunities, and houses the Adams County Fairgrounds, Adams County Museum, and two 18-hole golf courses. Today, Adams County is trying to meet and balance the needs of the Regional Park and Fairgrounds clientele and visitors while looking to the future. A comprehensive master plan will ensure stewardship of natural resources, meet recreational demands of a growing regional population, as well as study the continued marketability and financial viability of the improvements to the regional facility.

For this project, it’s critical that we get community input throughout the process, so we are asking for citizens and stakeholders to share their feedback and suggestions via email. Please check back often for updated materials.
