The Big Green Map is now bigger, greener and … mappier. The Philadelphia Water Department is working all around the city to implement green stormwater infrastructure such as porous paving, stormwater tree trenches and rain gardens, just to name a few. Check out our interactive, up-to-date Big Green Map to find out where PWD has either completed construction on a project or has one in the design phase. Each of these projects is a tool in preventing runoff from overburdening Philadelphia’s sewer system and keeping our rivers and streams clean by preventing combined sewer overflows.

In all, there are nearly 200 green infrastructure projects either completed or in design—be sure to zoom in on the map to see all the points appear in a given area, navigate the right-hand menu to view specific project types, and click on the green dots for more information on each project and a link to more information.
