"Philadelphia Has Announced a $1.6 Billion Plan To Transform the City Over the Next 20 Years by Embracing Its Storm Water - Instead of Hustling It Down Sewers and Into Rivers as Fast as Possible.
the Proposal, Which Several Experts Called the Nation's Most Ambitious, Reimagines the City as an Oasis of Rain Gardens, Green Roofs, Thousands of Additional Trees, Porous Pavement, and More.
All Would Act as Sponges To Absorb - or at Least Stall - the Billions of Gallons of Rainwater That Overwhelm the City Sewer System Every Year."
