All the talk in the news about ﬂooding recently reminded me of a conversation I had at the ofﬁce shortly after moving to New Orleans that went a little something like this: “Ok, I think I understand the scope of the project. Have we submitted the site plan to the City for stormwater management approval?”
“What stormwater management approval?”

In a city whose streets ﬂood after a 20 minute downpour, I found this very hard to believe. I now realize I’ve taken for granted the very progressive nature of the city I lived in for 13 years that requires a civil engineer to calculate rainfall percentages and a landscape architect to accommodate on-site retention of storm water. I realize the same approaches to stormwater management won’t hold true in an area with a high water table such as New Orleans but I’d thought I’d share this diagram from the Water Environment Research Foundation to get the ball rolling instead of… well… ﬂoating!
One thought on “Volume 52, Issue 5”
[…] Back in May, I was muttering about the lack of stormwater management best practices in the New Orleans zoning code but as it turns out, they aren’t far from implementation! A copy of proposed Article 23 of the Comprehensive Zoning Code (in draft form) recently came across my desk. In it, there is discussion of general landscape design standards that not only must be adhered to but approved in the course of obtaining a building permit. While under review for landscape plan approval, one must submit (among other things): “A stormwater management plan, including the pre-development runoff rate and the post-development runoff rate. The stormwater management plan must include: […]
