4 n <br /> Mr. Steve Ach • <br /> March 22, 1994 <br /> Page Six <br /> The flared ends outletting into the pond at the southwest corner of the plat <br /> should be adjusted to outlet at the water level to eliminate any potential <br /> erosion problem. <br /> A fencing layout and detail, as requested by City Council action, needs to be <br /> shown on the plans for the proposed pond at the southwest corner of the plat. <br /> • SHEET C4.3 <br /> The rim elevations on catch basin manholes #46 and #60 should be raised. <br /> There is a missing 930 contour around catch basin manhole #27 in the <br /> southeast corner of Freeport Avenue and the entrance road off North <br /> Highway 169. <br /> 3. Storm Sewer: <br /> The drainage calculations submitted appear to be adequate. However, a final review <br /> of the plan and profile construction documents needs to be made to verify the overall • <br /> adequacy of the system. <br /> A Corps of Engineers permit may be needed for work around the pond on the School <br /> District property. This should be submitted for a response from the Corps of <br /> Engineers. <br /> An MPCA permit will be required prior to beginning site grading. <br /> Consideration should be given to redirecting the storm sewer in front of the Target <br /> site southwesterly to the pond rather than northerly. <br /> An easement needs to be provided on the final plat to cover the storm sewer line from <br /> Freeport Avenue to the pond. <br /> If you have any questions regarding these comments, please call. <br /> Sincerely, <br /> MSA, CONSULTING ENGINEERS <br /> :/Y74, <br /> Terry J. Maurer, P.E. <br /> TJM:tp <br /> 230/152-2212.mar <br />
