Maybe I don't understand something here. Didn't the Sandy-type flooding occur when the storm surge raised the level of the Hudson River significantly above its normal banks?

How does pumping water into the Hudson River help that?

Exactly how much water would you have to pump, and pump it to where would address that problem?

16 million dollars I believe.

"...costs about $16 per mile to construct and $30,000 per mile..."

I think someone missed some zeros on that first number.

Pumps to be installed in Jersey City to prevent Sandy-type flooding; sea wall a maybe

Jersey City officials from several departments addressed members of the Historic Paulus Hook Association on Thursday night to discuss precautionary measures the city is taking to prevent flooding in the aftermath of Hurricane Sandy.

Municipal Utilities Authority Executive Director Dan Becht said the city is building a new pump station that will be able to pump nearly 5 million gallons of water per hour into the Hudson River.

The station located at the foot of Essex Street near the Colgate clock will be completed in two weeks, he said, adding four pumps costing a total of $1 million have been ordered for the facility.

The pumps are to be delivered by July and should be ready for use by September, Becht said.

The pumps will be used when the water level of the Hudson River makes it impossible for water from the city?s sewer system to empty into the river by gravity, Becht told about 75 members of the HPHA at the meeting in the basement of Saint Peter and Paul Orthodox Church on Grand Street.

The control panel for the pumps will be located in Liberty State Park, across the mouth of the Morris Canal, and it will be elevated. In the run-up to a possible storm, a portable generator would be taken to that location, he said.

A similar system is being considered for the low lying area behind the Jersey City Medical Center on Grand Street, Becht noted.

The MUA has hired an engineering firm to study the feasibly of channeling water from the city?s sewer system into the holding tank located at Liberty State Park. The tank would act like a buffer during a flood and water collected there could be later pumped out, Becht said.

Officials said they had looked as far a Holland for ways to fight flooding and noted there is a portable sea wall system available that can be bolted into place as a storm approaches. But the system costs about $16 per mile to construct and $30,000 per mile to be deployed each time a storm threatens.

He added that the sea wall, like other flooding solutions, would have to be approached regionally so as to not simply steer flood waters to lower lying areas. ?
