This project will include an approximate 1,102-foot extension of Runway 4-22, Taxiway A, and Taxiway B, along with associated site and storm drainage improvements and improvements to airport Navigational Aids (NAVAIDs), and airfield lighting and signage. The project will require up to 410,000 cubic yards of imported fill material on the 59-acre site for the construction of the runway and taxiway corridors and for build-up of the extended runway safety area (RSA) beyond the new Runway 4 end. Nearly 45,000 square yards of airfield pavement and over 12,600 square yards of perimeter vehicle service roadways will be constructed along with expansion of the airport’s perimeter security fence. An intermittent stream traversing the site will be relocated and encapsulated in a triple 66-inch diameter reinforced concrete pipe culvert approximately 2,080 feet long with another 2,000- plus linear feet of storm drain collection pipes including 18-inch and 24-inch diameter reinforced concrete pipes 30-inch and 36-inch diameter equivalent concrete arch pipes. Other site utility improvements will include the realignment of over 1,600 linear feet of 16” diameter ductile iron water line, including 30-inch steel casing pipes where airfield pavements are crossed. Electrical primary power lines will be rerouted to serve the NAVAIDs for the new runway length. The rerouting of power to the NAVAIDs will require coordination with Alabama Power for over 2,200 linear feet of new overhead primary power lines and installation of duct banks for over 1,000 feet of underground primary power, 550 feet of which will be directionally drilled.
