Lift Stations Adjournment - , ., CITY of ANDOVER SPECIAL ANDOVER CITY COUNCIL MEETING - APRIL 30, 1998 MINUTES A Special Meeting of the Andover City Council was called to order by Mayor Jack McKelvey on April 30, 1998, 9:37 p.rn., at the Andover City Hall, 1685 Crosstown Boulevard NW, Andover, Minnesota. Councilmembers present: Mike KlÚght, Ken Orttel Councilmembers absent: Bonnie Dehn, John Kunza Also present: City Engineer, Scott Erickson Public Works Superintendent, Frank Stone CommulÚty Development Director, Dave Carlberg City AdmilÚstrator, Richard Fursman Others DISCUSSION ON THE USE OF LIFT STATIONS The Council discussed the use of lift stations, as the policy has been to use gravity only when extending the SaIDtary sewer system. Councilmember Orttel stated he no longer has a problem with the techlÚcal portion of using lift stations, as he is satisfied with the operational and maintenance side of using them. The issue of expanding the MUSA boundary is a philosophical one and should be discussed by the entire Council. Jerry Windschitl- stated a set of plans are being designed for Chesterton Commons that would be designed differently if no lift station is going to be installed further down. Now it is being designed assuming there will be a lift station in the other projects further down. A smaller lift station would service a smaller part of his property and some others straight north of Chesterton Commons but south of CoRd 20. Some of those properties are in the MUSA and some are not. If the Council is opposed to lift stations, it would carry a different trunk size and depth. If the lift stations can be installed, there would be a smaller line at a shallower depth with a lift station to compensatè. The sewer trunk comes out of the ground at some point, and a lift station would carry it further into that group of properties to the railroad tracks to the north and east. Mr. Erickson reviewed the differences in laying the sewer line depending on whether or not a lift station is installed. An eight-inch pipe would adequately serve the remailÚng area if a lift station is installed, plus it would be installed at a steeper slope. Another issue is deciding on the depth of the lift station. The deeper the lift station, the further the MUSA boundary can be extended. A lift station will be more expensive than a gravity feed line. .. . .. I Special Andover City Council Meeting Minutes - April 30, 1998 Page 2 (Discussion on the Use of Lift Stations, Continued) Councilmember Orttel did not have a problem with using lift stations to service to the boundary of the current MUSA. That would be an engineering decision. Any expansion of the MUSA needs further discussion, as that would be a major policy decision. Mr. Erickson noted there is a limited capacity of the trunk line, and he thought it may be to where the MUSA boundary is now. He will check how much of the capacity is being used and the extent to which it wìll service in the City. Winslow Holasek - asked if lift stations could be used to solve his problem with the development of Winslow Hills 4th and ultimately to service a potential problem in the Nordeen Addition. He noted that with the change in location of the sewer trunk line going across Crosstown Boulevard at Bluebird instead of at Yellowpine, a considerable amount of capacity was lost. He felt it was a serious error on the part of the consulting engineers to deviate ITom the original plan. Councilmember Orttel felt the use of lift stations would be feasible. He didn't know if a lift station was the most efficient way to service the Nordeen Addition or other areas to the east. The Council generally agreed with Councilmember Orttel that lift stations could be used within the MUSA, but any expansion ofthe MUSA would require further research and discussion by the entire Council. Motion by Knight, Seconded by Orttel, to adjourn. Motion carried on a 3-Yes, 2-Absent (Dehn, Kunza) vote. The meeting adjourned at 10:0S p.m. Respectfully submitted. ,~c2~L Marcella A.
