The Federal Aviation Administration (FAA) approved a new Airport Layout Plan (ALP) for the Idaho County Airport during July 2003.  The ALP will guide future development of the Airport located one mile North of Grangeville. The plan includes a Capital Improvement Program for future airport improvements, assigns a location for an Automated Weather Station (AWOS), and designates two areas for industrial parks.

The Airport’s East Industrial Park is approximately 8.2 acres in size. The area in the Airport’s West Industrial Park is approximately three acres. Both parks are adjacent to City of Grangeville sewer and water lines and a paved perimeter access road that connects to U.S. Highway 95. Electrical power lines are nearby.
