Nueva Street Marina Dam Replacement

Nueva Street Marina Dam Replacement

This project replaces the aging Nueva Street Marina Dam, originally installed in the mid-1980s, with a modern air-filled inflatable dam. Managed during flood events when Flood Control Gate 5 is lowered, the new design includes removal of the existing Fabridam, site preparation, a control room for mechanical and electrical systems, and inlet/outlet piping. The upgrade enhances reliability and flood management along the San Antonio River Walk.
