Project Description

The O Street project was completed as a redevelopment project with the reconstruction of Dunbar High School, America’s first public high school for black students. The roadway contains a series of 33 bioretention cells lining both sides of the street that treat stormwater flowing towards two catch basins at the end of the block. The bioretention tree boxes each include at least one river birch which when mature will create an arching canopy over the sidewalk and street helping cool a highly urbanized neighborhood.

Best Ultra-Urban Project

This category recognizes the best application of green infrastructure (GI) practices that are built in highly urban areas to reduce flooding and pollutant delivery (more than 75% site impervious cover). Some examples include: green streets, walls, roofs or parking lots, rainwater harvesting systems, urban forestry practices, and permeable hardscapes.
