New Orleans to store 56,000 gallons of stormwater in new park
(UI) — According to NOLA.com, an “abused piece of property” will become a 4-acre park that will collect thousands of gallons of stormwater. The project aims to improve drainage in a flood-prone neighborhood in New Orleans.
The park will hold approximately 56,000 gallons of stormwater, easing pressure on New Orleans’ decaying drains and pump system. Dubbed the Bayou St. John Green Infrastructure project, the new park’s stormwater capacity is equivalent to 1,100 household bathtubs.
The park’s landscape utilizes short berms to send rainwater into a low spot ringed by a 150 ft. retention wall. In addition, tree roots, absorbent pavement, and soil will soak and filter excess water. Finally, a drain sitting above ground will tackle overflow, preventing nearby areas from flooding.
This is the 10th and largest green infrastructure project the Sewerage & Water Board (S&WB) has finished to meet federal ordinances that required of the New Orleans sewer system. While the park’s development costs $270,000, S&WB will also invest $2.5 million into various stormwater projects.
S&WB will spend the next three years testing water in different areas of the park to identify which pieces of green infrastructure are cleaning runoff most efficiently.
