==History==
During the Great Depression, the city was granted $12,000 by the Works Progress Administration (WPA), but that was later revoked in 1935 when the WPA learned the city only leased the airport.
During reconstruction of the original runway 12/30, the runway was renumbered to the current 13/31 designation. The Earth's magnetic north pole moves continuously, and when the original runway was constructed the magnetic headings were approximately 120 and 300. Magnetic north drifted over the life of the runway, such that by the time it was due for reconstruction, the magnetic headings were closer to 130 and 310.
