\n[Building a bigger wall: the Surge Barrier was the largest design-build project in the history of the Army Corps<\/a>;\u00a0construction began before design was complete, as a result of the pressing need to complete the barrier by the target date of 1 June 2011. According to Dredging Today<\/a>, the Barrier is “more than two miles long, 25 feet high and contains enough steel to build eight Eiffel Towers”:<\/em><\/p>\n

“During Hurricane Katrina\u2019s storm surge, a \u201cfunnel\u201d created by the levees along the Gulf Intracoastal Waterway and the levees along the Mississippi River Gulf Outlet allowed the surge that came across Lake Borgne to push into the heart of the city, and contributed to the failure of the section of the Industrial Canal that connects the Mississippi River to Lake Pontchartrain.<\/em><\/p>\n

By moving the surge barrier \u2014 the primary protection against flood surge \u2014 eight miles east of the city, the hope is the structure will stop much of any storm surge that could funnel into the city, Sinkler said.\u00a0Sealing off this area should take pressure off those internal floodwalls, which have also been strengthened since Katrina…”]<\/em><\/p><\/blockquote>\n
