EPA Gives Philly the Green Light on $2 Billion Project to Change Storm Water Treatment

Essentially, the plan calls for $2 billion worth of green resources—porous pavement, green roofs, and plenty of vegetation—that will revolutionize the way Philadelphia handles storm water. Instead of treating it as though it’s a waste product, the new system will use the water as a resource to cultivate the newly planted trees and plants that are expected to beautify the city and improve air quality. The 25-year plan is considered to be one of the most comprehensive and innovative in the country. [Inquirer]
