The initial steps are the same as getting a course approved for a public park. The Course Development area on this website has many documents to help with approving, designing and installing a new course. Check the Disc Golf Course Designers group to see if any members are located in your area. They can help you through all steps of the process. If there’s no one on that list nearby, do a search of courses near your zip code and contact some of the people listed as contacts for those courses. The websites for target manufacturers can not only provide information on their target models, but they have helpful advice on course design and installation. Contact information is available here.
