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 five
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.
Note: Private use airports with 2 mile buffers are only shown for airports that are listed within the FAA's National Flight Data Center (NFDC) database. Please contact Joshua Cothren, joshua.cothren@dot.wi.gov, (608) 266-6812 for additional information.
