New Storm-Surge Sector and Lift-Gate Plans To Be Aired

The Army Corps of Engineers’ New Orleans District expects on Dec. 4 to open a 30-day public comment period on plans to construct an Inner Harbor Navigation Canal (IHNC) Seabrook Floodgate Structure, consisting of a sector gate and two vertical lift gates in New Orleans. The new structure would tie into the Lake Pontchartrain levee system and operate in tandem with the IHNC Lake Borgne Surge Barrier, now under construction, to reduce the risk of storm damage. Comments will be taken on an Individual Environmental Report, which investigates alternative alignments and designs, potential impacts, construction methods and details.
