Tetra Tech INCA’s Lake Borgne Surge Barrier Earns Top Honor for National Engineering Excellence

A $1.1-billion response to the death and destruction of Hurricane Katrina has been named the year’s most outstanding engineering achievement in the 46th Annual Engineering Excellence Awards—a juried national competition sponsored by the American Council of Engineering Companies (ACEC).

More than 600 attended the black-tie Engineering Excellence Awards Gala, held last week in Washington, D.C., which recognized 147 preeminent engineering achievements from throughout the world.

In August 2005, one of the largest recorded storm surges in U.S. history—over 25 feet— entered the confluence of the Mississippi River Gulf Outlet and Gulf Intracoastal Waterway during Hurricane Katrina, overtopping a 4,000-foot-long levee section and causing widespread flooding, destruction and death in the New Orleans region.

The new Lake Borgne Surge Barrier—designed by Tetra Tech INCA of Bellevue, Wash., is a concrete and steel defense against any future Katrina-like assault. At 26 feet tall and nearly two miles long, it is the largest surge barrier of its kind in the world.  Built to withstand a once in a 100-year storm surge event, the new surge barrier effectively moves the first line of storm-surge defense more than 12 miles away from downtown New Orleans, and is now a model for floodgate and floodwall design worldwide.

Other top Engineering Excellence Award winners were:

Grand Award 

•            Aqua at Lakeshore East, Chicago, Ill., by Magnusson Klemencic Associates—majestically towering 87 stories from a once neglected industrial brownfield site, the 2.3-million square-foot mixed-use complex represents pioneering structural design for vertical construction.

•            Marina Bay Sands Integrated Resort, Singapore, by Arup—the new tourist destination in the heart of Marina Bay features three 55-story, asymmetrically curved luxury hotels, each topped and connected by a 2.5-acre landscaped rooftop, which is the world’s largest cantilevered public space.

•            U.S. Highway 82 Mississippi River Bridge, Washington County, Miss., by HNTB Corporation—a new 2,500-foot-long, three-span cable-stayed bridge that becomes the third longest of its type in the U.S., and a dazzling successor to the 1940s-era bridge it replaced.

•            Co-Digestion/Combined Heat and Power Improvements, Johnstown, N.Y., by Malcolm Pirnie, The Water Division of Arcadis—the first U.S. wastewater treatment plant that operates entirely on power recovered from the treatment processes—making it a “net zero” energy facility.

•            Elwha River Restoration, City of Port Angeles and Clallam County, Wash., by URS Corporation—the second largest National Park Service river restoration project in U.S. history prevents adverse environmental impact from 18 million cubic yards of trapped sediment during removal of two obsolete 1900s-era hydroelectric dams.

•            Harbor Drive Pedestrian Bridge, San Diego, Calif., by T.Y. Lin International—a graceful new 550-foot pedestrian bridge that is one of the longest self-anchored suspension bridges in the world, and a striking new gateway to downtown San Diego.

•            Yorkville Dam Safety Improvements/Bypass Channel, Yorkville, Ill., by Teng & Associates—water recreational attractions were enhanced while eliminating life-threatening downstream turbulence that claimed 28 drowning victims in the last 35 years.
