EPA Endorses Philly's $2B Plan to Go From Gray to Green?
On Tuesday, EPA Administrator Lisa Jackson and Philadelphia Mayor Michael Nutter signed an agreement that they say will lead to cleaner waters and a stronger economy for the City of Philadelphia. Jackson said the partnership will serve as a model for communities across the nation.
Instead of building more tunnels and pumping stations, the "Green City, Clean Waters" project is turning some of the city's hardened surfaces -- roofs, roads and other paved areas -- into "green areas" that absorb water or release it more slowly into storm drains.
