January 31, 2022

Revitalization of a neighborhood through GSI - Philadelphia’s Green City, Clean Waters Program and the American Street Corridor Project Green City program was created in 2011, this decade long goal consists of around 800 sites. American Street, one of these Green Stormwater Infrastructure (GSI) projects, is a historic wide rail corridor around American Street.

It rains more now, many storm water management systems along roadways and neighborhoods are over taxed and when it rains hard it floods. In Philadelphia there are many areas which have been assessed as flood prone areas. They have a shared sewer / StormWater management system. When it rains hard Philadelphian’s, poo goes into the Delaware river.   One solution is this new method of setting up a rain garden with trees and drilling storm water pipes vertically directly into the Aquifer below. This is just one out of the box solution to mitigate StormWater through diverting the water from the overtaxed shared storm water / sewer system.
