• • • COUNCIL MINUTES FEBRUARY 23, 1998 the provision of sanitary sewer, water main and roadway service. Mr. Powell reviewed the present status of this area, explaining that a lift station and sanitary sewer service was located east of the freeway, but not west of the freeway. Mr. Powell made Council aware that he received a communication from the Metropolitan Council. They prefer to serve this area by extending a gravity trunk sanitary sewer along Cedar Street from 20th Avenue to the eastern city limits and beyond by January 1, 2000. However, elevation will not permit connection to a gravity sewer, and the Metropolitan Council has indicated that it can only lower the line approximately five (5) of the necessary 12 feet. Additionally, a lift station would be required for the area to the north. The other option, according to Mr. Powell, is to install a lift station within the project area and extend a force main either to the future trunk or to another lift station. Since time is of the essence, the recommended course of action is to install a lift station on 21st Avenue with an 8 -inch force main along the north side of Cedar Street, jacking under I -35E, stringing the force main within a carrier pipe. The lift station would be installed along the east side of 21st Avenue approximately 400 to 500 feet south of the creek. Mr. Powell pointed out that this method is common for dealing with elevation discrepancies. Although the proposed utilities will be located along a roadway which divides Lino Lakes and Centerville, they will be installed in Lino Lakes. Mr. Powell explained that impact to the existing residence along the proposed utility route will be minimal, and that a 10 -foot right-of- way across that property would be required. He also explained that an 8 -inch stub for both sanitary sewer and water main would be extended to Northern Lights Boulevard within the Clearwater Creek Business Center. Roadway improvements would include a barrier curb, storm drainage to ponds that would overflow into Clearwater Creek, 12 -foot turn lanes to allow for turning onto 21st Avenue on both the east and west sides, and a 10 -ton design structure. Mr. Powell reviewed the costs involved in this project, which are contained in the feasibility report. The construction costs involved for the sanitary sewer would be $419,914 plus $62,690, $221,110 for the water main, $523,160 for the roadway, and $137,891 for the storm sewer. The total cost for the project is estimated to be $1,951,600. A joint powers agreement is required between Centerville and Lino Lakes for the roadway improvements, with costs of approximately $945,303 to be divided equally between the two cities. A draft agreement is attached to the feasibility report. In order to align with the overall Clearwater Creek Business Center development schedule, phasing has been discussed with the developer. Sharing of responsibility between the City and the developer is also being considered. Owners of property abutting the improvements will be assessed for lateral costs only, totaling $109,040 over assessable front footage, or $27.89 per front foot. Water main lateral costs only total $164,520, for $42.08 per front foot, and storm sewer and roadway, $472,650, or $120.88
