The system collects local runoff from Maplewood Drive, South <br /> <br />Clarkson Street, and South Pennsylvania. Additionally the outlet pipe from the <br /> <br /> <br />proposed Caley detention facility discharges directly into the storm sewer along <br /> <br />South Pennsylvania. This will eliminate the nuisance flows within the street from <br /> <br /> <br />the detention releases. <br /> <br />Cost of Proposed Improvements <br /> <br />A.
