Laughlin AFB proposes to implement several projects in order to improve its operational efficiency and to address ground and flight safety deficiencies at the airfield. Collectively, the projects would involve demolishing 23 facilities; replacing them with facilities that meet Air Force facility requirements, are energy efficient, have a lower operating cost than current facilities, enhance mission accomplishment, and improve the stormwater drainage system and slopes at the Laughlin AFB airfield. The Proposed Action would consist of the following separate projects * Demolish the Aerospace Physiology Facility (Building 380) and construct a new building directly southwest of the Flight Simulator Facility (Building 238) * Demolish 21 existing housing units (Buildings 9200-9220) and construct a new 37,391 square foot (SF) Student Officer Quarters at a site approximately 500 feet southwest of Building 446 * Demolish the existing outdoor small arms range (Building 1100), and construct a new 36,560 SF fully-contained indoor range approximately 600 feet to the north; and * Repair and improve stormwater drainage and steep slopes at the Laughlin AFB airfield. Alternatives for the proposed projects were evaluated as part of this EA including the No Action Alternative. Additionally, several alternatives were eliminated from further consideration during the scoping process.
