FINDING OF NO PRACTICABLE ALTERNATIVE (FONPA) CTA B140 FY25 DEMO
The Air Force is proposing demolition of a 14,618-square-foot gymnasium facility located within the boundaries of Joint Base San Antonio-Chapman Training Annex, Bexar County, Texas. The facility is located within the current 100-year floodplain associated with Medio Creek, a tributary of the San Antonio River. The Air Force has an obligation to comply with Executive Order (EO) 11988, Floodplain Management, to undertake the proposed action.
Air Force EO 11988 requirements include identification of alternatives to development in the floodplain, public notification of proposed action in the floodplain, an evaluation of potential adverse effects and identification of measures to minimize adverse effects, and preparation of a Finding of No Practicable Alternative document. Any alternatives to demolition considered must be in the floodplain.
The Air Force conducted an environmental analysis in accordance with 32 CFR Part 989, 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 EO 11988. The proposed action will result in no adverse effects to the natural and beneficial functions of the floodplain on JBSA property. 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 demolition activities within the 100-year floodplain 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 posted on 11 June 2024 on the Joint Base San Antonio public website and was posted for 30 days. No public comments were received.

FINDING OF NO PRACTICABLE ALTERNATIVE (FONPA) CoSA 2022-2027 Bond Project: Valley Hi Drainage Project (#23-03947)
The City of San Antonio (CoSA) is upgrading the stormwater drainage system that lies within the 100-year floodplain as designated by the Federal Emergency Management Agency (FEMA) at the perimeter of Joint Base San Antonio-Chapman Training Annex (JBSA-CTA). 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 involves demolition and reconstruction of stormwater conveyances to improve drainage as part of the CoSA 2022-2027 Bond Program. The work is to be done by CoSA and their contractors.
Any alternatives considered must be in the flood plain, as the stormwater drainage is in the floodplain. The Air Force conducted an environmental analysis in accordance with 32 CFR Part 989, 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. 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 posted on 17 December 2024 on the JBSA public website and was posted for 30 days. No public comments were received.
