THe Harvey Canal has present construction of a flood gate, that is to be closed to reduce water level in the canal in the event of a hurricane storm surge.
This is the $120 million project that is decribed as being held up by Clinton in 1995. It wasn't held up by Clinton, or at least he left no traces of holding it up, and the project was passed in 1996 and funding for it signed into law by Clinton.
I saw your earlier post. I was wrong. My map software searches faster if you give it a city to work with. Unfortunately, it thinks New Orleans and Gretna are two different cities.
I know, I know....no excuse...
(I see that that canal's walls range from 5.0 to 9.5 feet. That means a surge at least 5 feet above sea level.)
