Management planning for First State National Historical Park is an ongoing process consisting of visitor experience planning, infrastructure planning, and resource protection and management planning. While much of the planning is done by the National Park Service, there will be several calls for public input and public meetings, so please check back frequently or follow us by joining the Park's e-mail list (send a request here to join) or tracking our social media posts (Instagram & Facebook). Your opinions matter.
