EPA Issues Request for Data on Impervious Ground Cover

As the United States Environmental Protection Agency (EPA) crafts a draft national stormwater rule it continues to seek the expertise of landscape architects.

Earlier this year hundreds of landscape architects answered the call and submitted nearly 500 green infrastructure case studies to help demonstrate the economic, environmental, and social value of these techniques. As the rule making progresses, the EPA is seeking the additional input of ASLA members to help further its understanding of where, when, and why landscape architects use green infrastructure to manage stormwater. The EPA needs your technical expertise once again. 

Specifically EPA's Office of Water is looking for information on projects designed to reduce the amount of impervious cover on site to manage stormwater runoff.

Thank you in advance for taking the time to help the EPA address technical issues on behalf of ASLA.
