Bollinger Shipyards has delivered the Bayou Teche flood gate to Louisiana’s St. Mary Parish Levee District.
The steel flood gate, which measures 25 by 12 by 5.7 metres, is designed for a 25-year rain event and to provide flood risk reduction for a three-metre storm surge.
The Bayou Teche Flood Control Structure is designed to reduce the risk of heavy rain event and hurricane storm surge flooding when water comes through the Charenton Canal into Bayou Teche. It is located where the Charenton Canal meets Bayou Teche and will consist of a levee section from the northward high ground across the old Bayou Teche through Victory Island and across to the east side of the Bayou Teche.
The structure will protect an area containing 6,500 properties and the 13,500 people that reside there.
The Bayou Teche Flood Control Structure is the first of two projects Bollinger is contracted to build for the St. Mary Parish Levee District.
