SWEMA's Response  to "Proposed Use of Structural Stormwater BMPs In Alexandria."

The Stormwater Equipment Manufacturer’s Association (SWEMA) represents a diverse group of stormwater solutions providers as well as supporting associate and professional members. Due to the diverse perspective and expertise of its membership, SWEMA is uniquely qualified to provide a professional prospective on the “Proposed Use of Structural Stormwater BMPs in Alexandria” document that is currently being considered for implementation within the jurisdiction of Alexandria, Virginia.

SWEMA believes that all Stormwater BMPs, manufactured treatment devices and generic green infrastructure BMPs, have appropriate and suitable applications. To remove one sector of BMPs limits a designer’s ability to provide sound engineering solutions to solve complex environmental conditions. In the past, the City of Alexandria has been one of the most innovative jurisdictions in the country by promoting the use of sand filters and various underground stormwater devices. We commend the City of Alexandria for its unique history with respect to advancing stormwater management (SWM) both regionally and nationally.  PDF of the entire letter
