Rainfall should be diverted out of Uptown via the Mississippi River instead of carrying it all the way to Lake Pontchartrain, and major drainage ditches like the Monticello Canal should be expanded into interior floodplains and water-storage features, according to two recommendations that illustrate how New Orleans should be better managing its water instead of just pumping it away.
The Water Management Strategy presented by architect David Waggonner to a standing-room only crowd Thursday evening at Xavier University is a regional plan for making more efficient use of rainfall, slowing it down and storing it in natural canals to reduce the sinking of the land that contributes to flooding. The recommendations in the Uptown area are only a small part of the plan, but they illustrate some of its key elements and some of its challenges.
“We’re proposing this is a new era for water management,” Waggonner said. “It’s not just about flood protection any more. It’s really about quality and sustainability.”
