What is Rosedale?

The Rosedale Runoff Reduction Project (RRRP) is a holistic sustainable stormwater management project with the goal of removing 25 million gallons of sewage-polluted rain overflowing from Pittsburgh’s combined sewer into Nine Mile Run every year. We will achieve this through several phases of work. Phase 1, in 2015-16, will reduce 20 to 25 percent of the overflow by constructing 3 large green stormwater infrastructure (GSI) facilities and 40 stormwater management tree pits,  and by installing 200 rain barrels and 10 rain gardens throughout the contributing area shown on the map below. You can find out more about these installations on the Project Components page.

This map shows the location of the Nine Mile Run Watershed (outlined in blue) in relation to the Rosedale Runoff Reduction Project area (highlighted in red). In these areas you can find our large green stormwater infrastructure sites (yellow stars) and stormwater management tree pits (green dots) that are either constructed or under construction.

Historic Photos

Pictures of the past allow us to understand where we came from and where we are going. These historic photos show the Nine Mile Run tributaries in the RRRP area before there was a sewer system, and then the building of the system. We are adding to this conversation nearly 100 years later by building the next generation of green infrastructure in the Homewood area.
