NOTICES FOR EARLY PUBLIC REVIEW OF A PROPOSED ACTIVITY WITHIN THE 100-YEAR FLOODPLAIN – UNITED STATES AIR FORCE
25-018 LAK Stillman Holding Tank Replacement
The U.S. Air Force (USAF) is inviting public input on any practicable alternatives for a proposed activity within the 100-year floodplain at Joint Base San Antonio (JBSA)- Lackland, Texas. The Proposed Action involves removing and replacing an underground septic holding tank at the Stillman Park restroom (Building 1809). The facility and underground septic holding tank are located in a 100-year floodplain associated with Leon Creek, a tributary to the Medina River. The contractor will be responsible for complying with all applicable floodplain requirements for this project. There will be no modification to existing contours and minimal excavation to remove and replace the underground tank.
The USAF is performing environmental analysis in accordance with the National Environmental Policy Act to analyze the potential environmental impacts of the Proposed Action. This early public notice is required by Executive Order 11988 and has been prepared and made available to the public by the USAF in accordance with 32 CFR 989 and Air Force Manual 32-7003 for actions proposed within the 100-year floodplain.
Address written comments to the USAF 802 CES/CEIE, ATTN: NEPA Program Manager at 1555 Gott Street, JBSA-Lackland, TX 78236, or via email: 802CES.CEIE.NEPATeam@us.af.mil.” (Posted Nov. 20, 2025)
FINDING OF NO PRACTICABLE ALTERNATIVE (FONPA)
LAK Gateway Hills Golf Course Hole 18 Bridge Replacement
The 502d Civil Engineering Squadron (CES) is replacing a golf cart bridge that lies within the 100-year floodplain as designated by the Federal Emergency Management Agency (FEMA). Executive Order (EO) 11988, Floodplain Management, seeks to avoid construction of facilities or structures within floodplains “to reduce the risk of flood loss, to minimize the impact of floods on human safety, health and welfare and to restore and preserve the natural and beneficial values served by floodplains”. The proposed action will replace the current, failing condition cart bridge with a new steel truss bridge. The new steel truss bridge will provide a safely accessible route to Hole 18 at the Lackland Gateway Hills Golf Course.
Any alternatives considered must be in the flood plain, as the existing cart bridge is in the floodplain. The Air Force conducted an environmental analysis in accordance with the Air Force Environmental Impact Analysis Process. The analysis included an assessment of the impacts of the proposed action on flood risk to lives and property, and on the natural and beneficial values of floodplains, as described in the Water Resources Council’s implementation guidance to Executive Order 11988. The proposed action will result in no adverse effects to the natural and beneficial functions of the floodplain. FEMA Flood Insurance Rate Map (FIRM) for this site indicates that the flood height in the 100-year flood event would result in approximately 6.8 feet of water at the center of the drainage channel beneath the bridge location. This project would not cause adverse effects to the natural and beneficial functions of the floodplain, nor will it cause the height or velocity of floodwaters to create flood hazards. Due to this, this action is not considered as incompatible development in a floodplain, and it is the only practicable alternative.
In accordance with the requirements of EO 11988, the Air Force provided Early Public Notice for the proposed action to occur in a 100-year floodplain. The Early Public Notice was submitted on 25 August 2025 and remained posted for 30 days on the Joint Base San Antonio public website. No public comments were received. (Posted Nov. 13, 2025)
