The plans propose to construct a <br /> new single family home and tennis court. We have the following comments with regards to engineering <br /> matters: <br /> • The plans should show the driveway extending all the way to the road. In addition,any proposed <br /> grading within the right-of-way, including contour lines and spot elevations,should be shown on <br /> the plan. � <br /> • The plan should indicate where the existing catch basin shown to the west of the proposed tennis <br /> court outlets to. <br /> • It appears a proposed 952 contour line is missing along the south lot line. ' <br /> • The area between the garage and the north property line should be shown in more detail and at a <br /> larger scale. This area should identify all removals and show all proposed grading, including • <br /> contour lines and spot elevations. Any proposed retaining walls should be shown, including top <br /> and bottom of wall elevations. Slopes should not exceed 3:1. <br /> � The plan should provide information about restoration of areas in which removals are to occur, <br /> such as the tennis court and concrete patio by the lake. <br /> • The plans should show the existing sanitary sewer running between the house and the lake, as <br /> well as any manholes. <br /> � • The City should determine if it already has an existing utility easement over the sanitary sewer. If <br /> not, a 20'wide utility easement should be provided over the existing sanitary sewer. <br /> If you have any questions,please call me at(651) 604-4863. <br /> Yours very truly, <br /> BONESTR00 <br /> � ��� . <br /> � <br /> Tom Kellogg <br />
