[Ditter]

I have read that engineers suggested flood gates for the narrow opening to Lake Pontchartrain, to be closed during extremely high tides and storms. In hindsight that is what should have been done but the enviros objected. My grandfather survived the Galveston storm of 1900. Galveston Island was 8 feet high on the highest part. Grandfather said the storm surge was 2 feet deep in the second story of the house he rode out the storm in. The storm surge went across the island from the Gulf side into Galveston Bay and then the water came back across the island from the bay side, the returning water was just as destructive as the first time.

It has been reported that this plan was rejected because it would make it impossible to pump water out of the city with the gates closed. Excessive amounts of rain will cause flooding ... as well as actual overflow of bodies of water.
