Description

Two rain gardens were installed at the Mount Pleasant Highway Garage.  One is primarily shade tolerant and the second is for a sunny location. The rain gardens capture runoff from disconnected building downspouts and an entrance sidewalk to the building. Sited on a major thoroughfare on public land, this site serves as a demonstration site for the public and other municipal officials.
