Mr. Scott Hadicker November 4; 2003 Page Two should include concrete pedestrian ramps for the existing sidewalk on each side of the new driveway opening. Water service is proposed to be achieved by providing a wet tap on the existing water line located in the boulevard along Freeport Avenue and extending a six-inch water service to the new building. Sanitary sewer service is shown to be provided from the existing sanitary sewer line located on the south lot line. The connection indicates that there is an existing service stub located along the existing sanitary sewer line to service this lot. Both the sanitary sewer service and water service are appropriate for the proposed building. An existing 12-inch storm sewer line crosses the lot. An existing catch basin apparently will fall in the curb line of the new driveway. No storm sewer calculations have been provided at this point in time. Storm sewer runoff calculations should be submitted to indicate whether or not one catch basin is sufficient to pick up the runoff anticipated from the site. We believe that the existing catch basin on the site and the existing catch basin located on the ECM site have likely less capacity than needed for the runoff expected from the new driveway and building rooftop. We anticipate the need to construct additional catch basins with one located on the north side of the proposed driveway opening to pick up runoff internally prior to reaching the driveway and flowing out onto Freeport Avenue. The storm sewer calculations should be submitted and the grading plan modified to include any additional catch basins shown to be needed. If you have any questions regarding any of these comments, please call. Sincerely, Howard R. Green Company Ter~J~. a~urer, P.E. TJM:sw Ltr-110403-Harlicker Howard R, Green Company CONSULTING ENGINEERS
