The LSU AgCenter recently conducted an Urban Stormwater Academy to help engineers, architects and municipal officials learn about practices that will both reduce stormwater runoff and its contaminant load at construction sites.
The two-day workshop June 12-13 focused on stormwater best management practices (BMPs) for construction, post-construction and retrofitting stormwater treatment and detention areas, according to Dr. Rod Hendrick with the LSU AgCenter’s W. A. Callegari Environmental Center.
"On day one we provided background training to enable municipalities and builders and developers to comply with the recent Phase II addition to the stormwater act," Hendrick said. "And on day two we had them do some designs for permanent control measures."
Municipalities are facing a deadline for having ordinances in place to meet the requirements of Phase II of the stormwater regulations, Hendrick said.
These regulations are part of the Clean Water Act passed by Congress and administered by the U.S. Environmental Protection Agency. They were adopted by the state of Louisiana and are administered in the state by the Louisiana Department of Environmental Quality.
"The regulations require any construction site that’s a part of a project larger than 1 acre to have a stormwater management plan and to implement stormwater protective measures," Hendrick said. "They require municipalities to develop ordinances regulating construction and post-construction stormwater management.
"This will help reduce flooding from increased development and protect our streams, lakes and wetlands," he said.
Hendrick said the program featured two representatives from North Carolina State University. North Carolina has had an active program in stormwater management for more than 30 years.
The program was designed to help engineers, architects and municipal officials meet the requirements, which include:
–Public involvement and participation
–Construction site stormwater management
–Post-construction stormwater management
–Municipal pollution prevention
–Illicit discharge identification and elimination
Hendrick said the program looked at using ponds, rain gardens and constructed wetlands to reduce peak runoff and flooding both during and after construction.
"These things will eliminate increased flooding, and remediation will reduce pollutants in runoff from hard surfaces," Hendrick said.
