The preliminary plat should indicate drainage and utility easements <br />along lot lines. Drainage easements should also be provided over the ponding <br />area. <br />The drainage calculations should be provided for the storm sewer and pond <br />area. The storm sewer profile and the pond outlet control structure details <br />should be provided. The drainage ditch should be designed to minimize erosion <br />problems. <br />The roadway bank on the west side abutting Stubbs Bay Road should be graded <br />out. The ditch bottom should be set 3 feet below the existing centerline at <br />the property line. The backslope shall be graded to a 3:1 slope. Bituminous <br />flumes should be provided to drain the curb section at Stubbs Bay Road. <br />If you have any questions, please contact this office. <br />Yours very truly, <br />BONESTROC, ROSENE, ANDERLIK 6 ASSOCIATES, INC. <br />Glerin R.
