COVER SHEET DRAFT ENVIRONMENTAL ASSESSMENT FOR INSTALLATION DEVELOPMENT AT DYESS AFB, TEXAS Responsible Agency: 7th Bomb Wing (7 BW), Dyess Air Force Base (AFB), Texas. Proposed Action: The proposed actions consist of 14 different infrastructure projects on Dyess AFB. Point of Contact: Mr. Tommy Downing, Community Planner 7 CES/CENPP, Dyess AFB, 325-696-2050 Report Designation: Draft Environmental Assessment (EA) Abstract: Dyess AFB is preparing an EA for installation development to address deficiencies of function and capability in the facilities and infrastructure that result from obsolescence, deterioration, and evolving mission needs. The purpose of the installation development program is to provide a developmental path forward that incorporates known and projected mission requirements. Installation development has been planned relative to known constraints, functional use opportunities, and recommended courses of action to achieve optimal use of land, facilities and resources in support of installation missions. The proposed actions include 14 different projects. These projects are all within the boundaries of the installation and include new facility construction, building demolition, building renovation, infrastructure development (parking lots, utility lines), the relocation of the existing inert grenade range, and tree clearing. During the facility planning, floodplains were identified and avoided where possible. However, due to the extent of floodplains on Dyess AFB, particularly near the large diversion ditches, no practicable alternatives to approximately 8.35 acres of construction in floodplains were identified. No permanent changes to National Flood Insurance Program (NFIP) flood hazard areas or floodplains are anticipated to result from any of the proposed projects. The following resources were not carried forward for detailed analysis in this EA: Airspace, Aesthetics and Visual Resources, Surface Transportation, Hazardous Materials and Wastes, Socioeconomics, and Environmental Justice. Based on the analysis in the EA, implementing the proposed actions would not result in significant adverse impacts on the human or natural environment; therefore, preparing an Environmental Impact Statement (EIS) is not required.
