MINUTES CITY COUNCIL SEPTEMBER 28, 2005 2. The storm sewer outlet from the street into the east pond discharges above the normal water level. The outlet should be extended to allow discharge at the normal water level of the pond to prevent erosion problems. The orientation of the outlet should be towards the middle of the pond not towards a pond bank Co minimize erosion. As shown it appears that this storm sewer line is outside of the drainage and utility easements being provided. The finished ground elevation should be shown in the profile view of the plans and a drainage and utility easement be granted over the pipe. The width of the easement should be a minimum of twice the maximum depth of the pipe and be centered over the pipe. Von Riedel indicated acceptance of this recommendation. 3. There is an existing sanitary sewer line along the west side of Lot 1 that is approximaCely 11 feeC deep. The plat is currently providing a 20-foot drainage and utility easement on the west side of Lot 1. The sanitary sewer is not centered within the easement currenCly being granted; therefore additional easement width should be provided to allow for maintenance. Given the 11-foot depth of the sewer it is our recommendation that the easement be extended Co the easC a minimum of 11 feet fi~om centerline of the pipe. Von Riedel indicated acceptance of this recommendation. 4. Hydrant valves should be placed 2'6" from the hydrant. Von Riedel indicated acceptance of this recommendation. 5. The Mn/DOT storm sewer pipe should be shown in both plan and profile view. Due to the age of the storm sewer pipe the City should require that the storm sewer pipe within the development be replaced with reinforced concrete pipe. This was previously agreed to by the Developer but is not shown in the final plans. The Developer should also provide commenC from Mn/DOT as the replacement material and size and docmnent approval from Mn/DOT for the work. Gardener pointed out that the storm sewer pipe is under the jurisdiction of MN DOT, and questioned the developer's ability to replace this pipe. Von Riedel indicated that if MN DOT approves the replacement of the pipe, he was agreeable with the recommendation. 6. The water main must be looped thru the entire development up to water main in Viking Drive. This was also a previous requirement Chat was agreed to by the Developer but is not shown on the final plans. Von Riedel indicated that they will not be able to take the water main through private property to loop it. The City Administrator pointed out that this recommendation was part of the Preliminary Plat approval, and was noC contested in court proceedings. The City Engineer noted that a dual line could be run in order to accomplish the loop. 17
