The Army Corps is currently constructing the Southeast Louisiana Urban Flood Control Project (SELA) in Orleans and Jefferson parishes. This work includes construction of large underground box culverts that will work to get rain water off the streets faster and into the box culverts.
The Army Corps' website has additional information on the specifics of the project. The improvements generally support the parishes' master drainage plan and provides flood risk reduction up to a level associated with a 10-year rainfall event. A 10-year event is a rain storm that has a 10% annual probability of occurrence and equates to approximately 9 inches of rain over a 24-hour period for an area. The project was funded by congress following the May 1995 flooding and received additional funding after Hurricanes Katrina and Rita.
There are six on-going projects in Uptown New Orleans, two in New Orleans East and 10 in Jefferson Parish. After each construction contract is complete, a separate landscaping contract will be awarded to return the landscaping to what was there prior. Any changes to the landscaping would come from the city. For example, Napoleon Avenue will have a walking path added to the neutral ground that is funded by the city.
Below are the on-going projects in Orleans Parish (along with construction limits) with estimated completion dates.
