Ms. Kathy Glanzer July 9, 1999 Page Two C. Preliminary grading and erosion control plan ♦ The single driveway into this site shows a 5% grade from Rice Street down into the site. The ordinance does allow a maximum driveway grade of 5 %. However, there is no flat area of any kind provided for stopping and then accelerating onto Rice Street. The driveway faces east, we can assume that at times in the winter it will be relatively slippery and difficult for cars to come to a stop and then accelerate onto Rice Street. ♦ The grading plan indicates total grading on the site, therefore there will be virtually no existing trees on the site that will be saved. ♦ The grading plan shows grading activities well within the 25 foot setback from the shoreline. ♦ There is an existing storm sewer pipe shown along Rice Street, at the north end of the site it shows a flared end section coming out into the property. The flow arrows on the existing pipe indicates that the flow is from the site to Rice Street. However, the existing contours on the site would indicate the flow would be in the opposite direction and actually onto the site. This should be verified. If this existing storm sewer does in fact drain onto the site it needs to be accounted for in the storm sewer design. • The pond shown on the east side of the property should be provided with a emergency overflow. ♦ No storm sewage calculations have been submitted for this site. These need to be submitted, reviewed, and approved. • There is a small 15 foot square shown near the west side of the pond. This is not labeled but it appears to be some type of gazebo structure for the office tenants to utilize. It is shown in an area of relatively steep grades. It is unclear what the idea is here and how this will work. • There is an existing storm sewer pipe shown crossing the southeast corner of the property. It is unclear where this pipe comes from, who owns it, or whether the easement needs to be provided on this site for this pipe. ♦ There is relativity high retaining walls proposed on both the north and the south end of the site. D. Utility Plan • Sanitary sewer is shown to come from the north and service the buildings from behind on the east side. This sewer should be re- designed to be in the parking area. With its current location behind the buildings it will be impossible to access for maintenance purposes. Howa O: \PROJ1807250j \0240\250- 0904.juIy99.doc C I n any PAGE 148
