Welch Comer completed a master plan for Chatcolet Marina for Idaho Department of Parks and Recreation (IDPR). Chatcolet Marina is located on the west shoreline of Chatcolet Lake within Heyburn State Park. IDPR has plans to expand the existing marina from 26 boat slips to 140 boat slips. Another purpose for the plan was the Panhandle Health District requirement to upgrade sewer facilities to existing privately-owned boat garages and float homes. The report describes the process for relocation of the float homes, consolidation of the boat garages, and the reconstruction of the marina.
