JBSA Floodplain Actions


CTA Medio Creek Sewer Line 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-Chapman Training Annex (JBSA-CTA), Texas.  The Proposed Action involves repairing by replacing 40 linear feet of sanitary sewer line. The work will be conducted by American Water for the 802 Civil Engineer Squadron.  The project will support efforts to upgrade JBSA’s utility lines and prevent sewer leaks and spills.  The sewer line is located in a 100-year floodplain associated with Medio Creek, which is a tributary to Medina River.  There will be no modification to existing contours and there will be minimal excavation.  Rip rap will be added on the bank to prevent erosion around the sewer line.

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.
