Plum and Walnut St. Green Intersection

State/Territory:

Located at the intersection of North Plum Street and East Walnut Street, the site of numerous vehicle accidents from a confusing merge lane, the Plum and Walnut Green Intersection Project integrated green infrastructure (GI), enhanced pedestrian amenities and a roadway realignment to improve traffic safety and reduce stormwater runoff. The GI project included a series of nature-based solutions including bioretention, permeable pavers, infiltration beds, and tree plantings. The combination of practices infiltrate, capture, and reuse rainfall, all while providing an aesthetically pleasing amenity for local businesses near the intersection. The project lowers traffic speeds by 5 mph and reduces stormwater runoff by 1.4 million gallons annually.
