Nueva Street Marina Dam Replacement

Nueva Street Marina Dam Replacement

The Nueva Street Marina Dam is a temporary dam for the Nueva Street Marina when Flood Control Gate 5 must be lowered during or in preparation of a flooding event on the San Antonio River Walk. The existing gate was installed in the mid-1980s with an expected serviceable life of 30 years. Given the expiration of useful life and after review of several options, an air-filled inflatable dam replacement was selected. The completed design included removal of the current Fabridam, site preparation, control room housing mechanical and electrical equipment, and inlet/outlet piping to an air-filled dam replacement in place of a water-filled dam.
