Airport References Points (ARP) - An airport reference point is the center point of an airport, located at the geometric center of all the usable runways. They are based on requirements outlined in chapter 5 of the Wisconsin Facilities Development Manual.
Airport Reference Point Buffers - The airport reference point buffers are either a two mile or a six mile buffer ring around each of the airport reference points. Buffer rings for each airport have been developed by WisDOT and are based on requirements outlined in chapter 5 of the Wisconsin Facilities Development Manual.
This data provides general guidance and airport information for highway construction projects in and around Wisconsin airports.
