Ms. Michele McPherson <br />April 17, 2002 <br />Page Two <br /> <br />Detailed storm drainage calculations were not submitted with this development. <br />Storm sewer calculations will need to be submitted, reviewed, and approved prior <br />to final approval of Kliever Lake Fields East Addition. The high water elevation and <br />emergency overflow elevation for the proposed ponds are shown on the grading <br />plan. The emergency overflow elevation is shown at 901.0. According to City <br />policy, the lowest opening on any adjacent building needs to be a minimum of one <br />foot above the emergency overflow. Every building on the south side of Street A is <br />shown lower than this elevation at 900.5. These need to be revised. <br /> <br />Bryan Adams of the Elk River Municipal Utilities has asked for the watermain on <br />Street A and the unnamed street accessing Fillmore Street to be increased in size <br />from 8-inch to 10-inch. As done previously with Kliever Lake Fields Addition, there <br />will be a trunk watermain credit given back for the increase in size between 8-inch <br />and 10-inch. <br /> <br />It will be necessary to determine the depth of sanitary sewer needed at the <br />southeast part of the plat at a later date. We will work with the Developer's <br />Engineer when they prepare final construction drawings. <br /> <br />If you have any questions regarding these comments, please call. <br />Sincerely, <br /> <br />Howard R.
