COUNCIL MEETING APRIL 22, 1996 OSM, Inc. to prepare a feasibility study investigating the street and utility services. Staff, residents and the consultants have met a number of times to discuss the project. Mr. Ahrens said hopefully the improvement can be ordered in the next meeting or so. Mr. Ahrens introduced Bruce Houle, project engineer for OSM, and asked him to discuss the utility improvements. The proposed improvement consists of a number of items. The utility improvements are a major issue although the road issue, which Dave Mitchell of OSM will outline, is the primary concern. Mr. Mitchell will also talk about pedestrian issues. At the conclusion Mr. Ahrens will discuss the project assessments and the project schedule. Mr. Houle used the overhead project and explained that he will discuss the utilities that will be needed to service the area. The area consists of the school site, the areas north of Elm Street and north of the Shores of Marshan Lake. He said the only feasible way to tie this area into the trunk sanitary sewer line, which is off of Apollo Drive north of I35W, is to jack the line from Apollo Drive south under I35W and then extend a gravity line south along the Fourth Avenue right-of-way. The gravity line will service the school area as well as all of the parcels west of Lake Drive (TH 49) and east of Fourth Avenue. A stub will also be provided to serve the areas south of I35W for any development that would occur to the east of Lake Drive. This plan will enable the existing force near the Shores of Marshan subdivision and the new condominium development to be rerouted into the gravity line. The existing line will not have compacity when this area is fully developed. Mr. Houle noted that there is an existing 12 inch trunk water main along Elm Street which services the Shores of Marshan Lake subdivision at this time. There is also an existing 16 inch water main line along Apollo Drive. To serve the school site and other areas just outlined, the water main along Apollo Drive will be extended and jacked south under I35W with a 12 inch water line and then it would be looped to the existing water main with an eight inch water line. This system will provide adequate fire protection for the proposed school as well as all the areas east of Fourth Avenue and south of I35W. Mr. Houle used the street configuration noted as Option F to show the proposed drainage. The drainage along the roadway (new Elm Street to Lake Drive) would be drained north to a proposed pond. This pond would receive drainage from about two- thirds of the school site. The pond would be about four acres in size and would handle all flood storage. This is a Rice Creek Watershed District (RCWD) requirement. Mr. Houle outlined the cost for construction of the required utility systems. The cost does not include the cost of easement or right-of-way acquisition. The cost to construct utilities which would be installed, if Option F were approved for the street alignment, would be about $800,000.00. This cost to provide utility services to the area, if Elm Street Option F is approved, is less costly that if Option B was selected. He explained the reasons for the difference in costs. PAGE 9
