Shoreview, Minn., is betting on a new “green” concrete paving method that lets rainwater pass right through the street surface to prevent damaging runoff. Pervious concrete _ made of gravel and cement minus the sand that gives regular concrete its impenetrable density _ has the porous quality of a Rice Krispies bar.
Because it will allow water to drain straight to the ground below, Shoreview will install about a mile of pervious concrete streets without storm sewers in a neighborhood on Lake Owasso.
…and no drain to let the water run off…?
