"Through this agenda, we'll help cities and towns across the nation clean up their waters and strengthen their communities by supporting and expanding green infrastructure," said Deputy Administrator Bob Perciasepe, who announced the agenda at a Green Street, Green Jobs conference focused on fostering green infrastructure in the Washington, DC metropolitan area. "Green infrastructure changes improve the health of our waters while creating local jobs, saving communities money and making them healthier and more prosperous places to raise a family and start a business."
Stormwater is one of the most widespread challenges to water quality in the nation. Large volumes of polluted stormwater degrade our nation's rivers, lakes and aquatic habitats and contribute to downstream flooding. Green infrastructure captures and filters pollutants by passing stormwater through soils and retaining it on site. Effective green infrastructure tools and techniques include green roofs, permeable materials, alternative designs for streets and buildings, trees, rain gardens and rain harvesting systems.
As part of the strategy, EPA will work with partners including local governments, watershed groups, tribes and others in 10 cities that have utilized green infrastructure and have plans for additional projects. EPA will encourage and support expanded use of green infrastructure in these cities and highlight them as models for other municipalities around the country. The nine cities, in addition to Kansas City are: Austin, TX; Boston, MA.; Cleveland, OH; Denver, CO.; Jacksonville, FL; Los Angeles, CA; Puyallup, WA; Syracuse, NY; and Washington, DC and neighboring Anacostia Watershed communities.
Energy savings is one of the greatest benefits of green infrastructure. On and around buildings, green infrastructure can reduce heating and cooling costs. For example, according to the EPA, green roofs reduce a building's energy costs by 10 to 15 percent, and an additional 10 percent of urban tree canopy can provide 5 to 10 percent energy savings from shading and wind-blocking. Green infrastructure also conserves energy by reducing the amount of stormwater entering combined collection and treatment systems, which reduces the amount of wastewater processed at treatment plants.
