Pearl Street and Sidewalks Improvements
City of Columbus, Ohio

Rii is assisting the City of Columbus in its commitment to ‘going green’ by experimenting with various solutions to help create ‘Cool Communities.’  For its Pearl Street and Sidewalks Improvement Project, the City will be using pervious concrete pavement for its sidewalks, curbs and gutters to reduce stormwater runoff.  Pervious concrete pavement with detention, in addition to stormwater control, also can gain LEED credits with USGBC.

Other green elements include paving with light color or porous materials and planting/protecting trees.  Hot pavement can reach more than 160 degrees, cooking surface contaminants in stormwater runoff.  In addition, rain cannot soak into impervious pavement, so they wash over hot surfaces and dump hot contaminated water into streams. Because lack of trees along the streets also create urban heat islands, allowing the hot air to cook the atmosphere and produce smog, additional trees will be planted along the corridors to help improve the air quality in the area.
