And after three days of delays, the Corps and a swelling army of private contractors slowly began to set the stage for draining the hundreds of billions of gallons of floodwaters from the city.
The plan was to close the holes that the storm tides had opened and break open new holes in places where the levees were holding water in the city rather than letting it out.
A train of dump trucks and a yellow bulldozer began laying a narrow, temporary road of black rubble and gravel from dry ground to the north end of the 300-foot breach in a wall of the 17th Street Canal, through which most of the floodwaters passed. At the same time, heavy-lift helicopters lowered hundreds of huge sandbags into the south end of the gap.
The height of the water in the streets and the adjoining lake had leveled off, so water was no longer rising. The authorities were hopeful that the breach could be slowly, if temporarily, blocked. At the same time, Lt. Gen. Carl Strock, commander of the Corps, said he was concerned about storms forming in the Atlantic."
