HIGHLANDS RANCH, Colo.--(BUSINESS WIRE)-- ARCADIS (EURONEXT: ARCAD), the leading pure play global engineering and consultancy firm, announced today it received two honor awards from the American Council of Engineering Companies (ACEC) last night for its work on both the Seabrook Sector Gate Complex and St. Bernard-Chalmette Loop Levee Floodwall System. Bioengineering ARCADIS LLC, a small business venture established as a U.S. Small Business Association mentor-protégé entity, provided design services for both projects which are part of the Hurricane Storm Damage Risk Reduction System (HSDRRS), constructed by the U.S. Army Corps of Engineers for the high risk areas of New Orleans.

The Seabrook Sector Gate Complex spans the 500-ft wide New Orleans Inner Harbor Navigation Canal (IHNC) at Lake Pontchartrain and works in conjunction with other elements of the HSDRRS. Bioengineering ARCADIS LLC provided design team management for the project. The Seabrook Complex includes a 95-ft wide navigable sector gate flanked by two 50-ft wide flow control vertical lift gates, concrete T-walls, a roadway ramp, and upgrades to a railroad floodgate. During a storm event, the gates are closed to form a continuous barrier to reduce flood risk for some of the areas hardest hit by Hurricane Katrina – New Orleans East, metro New Orleans, Gentilly, the Ninth Ward and St. Bernard Parish.

The St. Bernard-Chalmette Loop Levee Floodwall System is another major element of the overall HSDRRS and was engineered by Bioengineering ARCADIS, LLC. The 23-mile-long Chalmette floodwall project included raising and strengthening six levee reaches and constructing two 56-ft sector gates, five highway/railroad closure gates, a pump station, and ties to the Mississippi River Levee system. Elements of this system also included designing bypass channels around construction areas to provide a path for fish passage and maintain fresh water flow to marsh areas. Completed in record time and on budget, the St. Bernard Floodwall System is now the main line of defense for approximately 40,000 residents and numerous businesses.

“We are honored to receive this recognition from ACEC for the design work we completed in New Orleans,” said Steve Blake, chief executive officer for ARCADIS U.S. “Our world-class thought leaders delivered their best and brightest ideas to reduce flood risk for the citizens of New Orleans, while balancing the built with the natural environment. Hurricane Isaac was no match for the expertly designed system, which worked as intended during the 2012 storm event.”

In addition to the national awards, ARCADIS was recognized by ACEC NY for its work on the Bay Park Sewage Treatment Plant and Westchester County Water District Number 3 projects.
