No option achievable before Hurricane season 2009 Raising the walls

Constructability challenges Limited Right of Way and room for construction

8.5 miles total of floodwalls and gates 4.2 miles South of I-10 overpass on IHNC

Impacts on commercial industry Temporary Barge Gate

Constructability challenges Akin to permanent structure

Potential for NEPA impacts Impacts on navigation

Constrictions Potential for NEPA impacts Impacts on navigation Real Estate

Interim Protection Challenges

Barge Gate Reviewing designs based on updated 100yr elevation design criteria

Differential head, Impact loads Required Real Estate owned by NASA, Port of New Orleans

Allows for expedited real estate acquisition process ERDC optimizing channel opening for velocity and navigation

Goal is to eliminate center pier and one bulkhead Eases navigation and environmental impact concerns

MVN/HPO Environmental determining best method to achieve NEPA compliance – ERDC analysis is crucial

HPO Contracting determining best expedited means for contract mechanisms MVN H&H modeling inundation maps for 4 scenarios (Current conditions, With

Barge Gate, Walls S of I-10 at el. 15’, All walls on IHNC at el. 15’) Working in conjunction with A-E to refine cost, all aspects of design and

construction schedules, and ways to expedite delivery Final Schedule and Cost analysis to be complete once refined designs are

complete – joint HPO/A-E effort Goal remains all efforts complete NLT 31 AUG 07
