Description
WBV-16.1 - Segnette PS to New Westwego Pump Station Floodwall - Phase 1
Authorized level of protection.
WBV-16.2 - Bayou Segnette Complex
Sector gate, pump station, navigation channel re-alignment and levee section across Bayou Segnette.
The project consists of constructing levees, T-Walls, a 400 cfs drainage pumping station, and a 56' wide sector gate to provide protection against the 1% storm surge. Beginning at the tie-in to the new fronting protection in front of the Bayou Segnette Pump Station, a new T-wall is proposed proceeding north on the west side of Bayou Segnette on similar alignment as the existing levee and interim sheet pile floodwall. Approximately 150 feet north of this point, the T-wall will turn easterly and will run parallel to the pump station access road and then cross Bayou Segnette on a new alignment. The Bayou Segnette closure will include a hybrid T-wall tying into a 400 cfs pump station separated from a 56-foot wide sector gate by a T-wall. A 60-foot wide navigation channel is proposed upstream and downstream of the sector gate. The closure section in Bayou Segnette will be built last to maintain navigation during concurrent construction of the pump station and the sector gate. A T-wall will extend from the sector gate and transition into an earthen levee. The earthen levee will extend southeasterly to the newly construction flood wall north of Lapalco Boulevard.
