"Everyone knows what's going on in Philadelphia"

Simulation of green infrastructure in Philadelphia (Green City, Clean Waters)

That title quote from EPA Administrator Lisa P. Jackson—in reference to Philadelphia's forward-thinking strategies in stormwater management, green infrastructure and sustainable development—appeared in an article this morning in the Philadelphia Inquirer. It's also the reason that Mayor Michael Nutter, Philadelphia Water Department Commissioner Howard Neukrug and Deputy Mayor for Transportation Rina Cutler were invited by the EPA to travel to Rio de Janeiro (not pictured, above) this week to advise and observe Brazil's own green infrastructure initiative: a massive undertaking with a $200 billion price tag. PWD's Green City, Clean Waters plan was cited as a national model at the forum in Rio.
