Ms. Michele McPherson <br />January 9, 2001 <br />Page Two <br /> <br />submitted, reviewed, and approved. Storm sewer calculations should provide for <br />emergency overflows of each pond and also provide detailed calculations relative to the <br />pdvate ditch which enters the site from the northeast and exits under County Road 13. <br /> <br />There is storm sewer shown behind Lots 1/2 and 3/4 which seems excessive. It appears <br />that this area could be gradually graded so that storm water would flow to a point further <br />west where it could be picked up, minimizing the amount of storm sewer pipe. <br /> <br />There is a storm sewer stub between Buildings 35/36 and 37/38 which collects water in the <br />rear yards. It appears that this storm sewer could be eliminated by grading this area to <br />drain to the east out to the street. <br /> <br />o <br /> <br />The two cul-de-sacs on the plan will require either cross-gutters or storm sewer catch <br />basins on either side of the cul-de-sac to collect the water flowing down the street. <br /> <br />o <br /> <br />There is a retaining wall immediately across the street from Buildings 17/18. This wall <br />could be minimized in height by tightening up the proposed contours behind the wall. Aisc, <br />we would suggest the wall be moved further away from the street to provide more room for <br />snow storage. <br /> <br />The next submittal should have the existing contours labeled. Currently, there are no <br />elevations shown on the existing contours which makes it difficult to review the grading <br />plan. <br /> <br />° <br /> <br />The wetland filling and mitigation area will need to be reviewed by Steve Rohlf and the <br />Technical Evaluation Panel if he determines it is necessary. <br /> <br />° <br /> <br />If you have <br /> <br />The major pond in the eastern part of the development has 3:1 contours leading down from <br />the street. An attempt should be made to get a larger, relatively flat area behind the curb <br />and gutter prior to the in-slope into the pond. Currently, the 3:1 slope appears to start <br />almost at the back of curb leading down into the pond. Otherwise, some other method of <br />protecting the street traffic from the pond in-slope will be necessary. <br /> <br />any questions regarding these comments, please call. <br /> <br />Sincerely, <br /> <br />Howard R.
