To collect stormwater runoff beneath newly constructed infiltration swales and convey it away from known flooding locations, a network of Reinforced Concrete Pipe (RCP) and High Density Polyethylene pipes (HDPE) that range in size from four inches to 24 inches will be installed. These new pipes will connect at several locations on each street to the existing pipes, which will remain in the ground throughout the district. That HDPE pipe will then connect to new concrete storm sewer pipes to bring the water to the new detention basin before it is released slowly into the Diehl Consolidated Drain.
Along Dean Avenue, Auburn Street, Phillips Avenue, Adelpha Avenue, and Burton Avenue, the roadside swales will be excavated and perforated plastic pipe will be installed. The infiltration swales will then be constructed on each side of the road.
Dean Avenue and Auburn Street from Richard Street south to Holt Road will then be crushed and shaped and overlaid with new asphalt pavement. Phillips Avenue and Burton Avenue, from their north ends to Holt Road, will be crushed and shaped and overlaid with new asphalt pavement. Adelpha Avenue from Kathy Kourt to Holt Road will be crushed and shaped and overlaid with new asphalt pavement.
Between Auburn Street and Phillips Avenue, new storm sewer pipe will be bored and jacked between several properties. This means that construction crews won’t cut a trench to lay the pipe. Instead, they will dig two pits and then push the pipe through the ground from one pit to another.
