The LPV-9.2 project constructed a continuous line of hurricane flood protections across reinforced and extended discharge basins at Jefferson Parish Pumping Stations No. 1 through 4, plus modifications to two existing breakwaters at Stations No. 2 and 3.
The pump stations and breakwaters play a key role in New Orleans because they link the network of drainage canals in the city. However, these stations operate 24/7, so pumping could not be shut down during construction. At any time, if necessary, the construction area would be flooded, so the pumps could start pushing water from the canals into the lake. The team had to be ready to evacuate people, equipment and materials within a 15-minute window. There were 53 instances when it rained during construction, and during each of those, the team had to completely and safely demobilize all equipment and personnel from the worksite so that the active pumping station could operate.
