Green, Complete and Smart: Build Green vs. Grey

Communities are turning to innovative stormwater management solutions to solve local and regional stormwater challenges. For example, in the nation’s capital, DC agencies recently modified a plan that predominately relied on grey infrastructure to instead partially replace the grey infrastructure with green infrastructure in targeted existing impervious areas. These green installations will serve to mitigate flooding and stormwater issues to the same capacity but with many more environmental and community benefits.

The panel will discuss stormwater challenges through several examples located throughout the country, and the impact of vegetated systems to manage stormwater in local and regional jurisdictions. One example that will be discussed is The American Society of Landscape Architects (ASLA) proposed Green Street Demonstration Project in the Chinatown neighborhood of Washington D.C. where the ASLA headquarters are based. The project seeks to serve as an example for such green, complete, and smart street design. The plan transforms an underperforming street corridor into a showpiece of both green infrastructure technologies and complete street approaches.
