Drainage requirements get
special attention

Despite that, making sure that the rain water is cleaned before it goes into a bayou is “important stuff,” said Dana Brown, one of the principals in Brown+ Danos Landdesign Inc.
Federal, state and local water quality regulations that require the runoff water first be cleaned naturally, Brown said. Other regulations, primarily local, require Woman’s to make sure that water drains off the campus at the same rate after the hospital is built as before.

Brown+Danos is responsible for making sure Woman’s Hospital’s new campus meets the water quality regulations.
In order to comply with both sets of rules, Woman’s had to solve the drainage problems for the campus, and for some of the surrounding properties, project manager Stan Shelton said.
Woman’s is doing this, in part, by creating an 18-acre lake, constructing some wetlands and building 165,000 square feet of bioswales, Brown said.
What’s a bioswale? “Think of it as an eco-friendly ditch,” Brown said.
Except in this case, the ditch is wider and flatter and covered with water-loving plants, Brown said.
Or as Shelton said, basically the trees and landscaping in the parking lots are serving two purposes: one aesthetic and one practical.
The water is filtered as it flows through the bioswales, Brown said. Some water is used by the plants, some is absorbed by the ground, and some may drain down into a gravel sub-base beneath the plants, into a perforated pipe and then out.
Filtering the water also slows the rate of runoff, Brown said.
But the main idea is to make sure that the water is cleaner when it reaches Bayou Manchac or the Amite River and eventually Lake Pontchartrain, Brown said.
“A lot of our water bodies are impaired, and the only way to clean them up is if every one of us, on new projects, tries these kinds of things,” Brown said, “and where we can retrofit other projects.”
