(612) 4474230 / Fax (612) 447-4245 PRELIMINARY REPORT AND ESTIMATE OF COST FOR THE CITY OF PRIOR LAKE PUBLIC IMPROVEMENT PROJECT NO. 90-13 SANITARY SEWER, WATERMAIN, STORM SEWER, CONCRETE CURB AND GUTTER, BITUMINOUS SURFACING, AND APPURTENANT WORK MARCH 19, 1990 I. TYPE OF WORK The general nature of the improvement project is for the installation of sanitary sewer, watermain, storm sewer and street improvements to Ash Circle, Hampton street and Fernda1e Avenue lying within the Second and Third Additions to North Shore Oaks. This project also involves the installation of sanitary sewer and watermain through the city park located in the Third and Fifth Additions to North Shore Oaks. II. LOCATION OF THE PROJECT The project area is located in the Northerly portion of the City of Prior Lake in the north half of Section 25, Township 115 North, Range 22 West, Scott County, Minnesota and in the area known as the Second, Third, and Fifth Additions to North Shore Oaks (See attached map). The streets to be improved in this area are Hampton Street from Ferndale Avenue to Fisher Avenue, Ash Circle within the Third Addition to North Shore Oaks, and Ferndale Avenue from the south plat line of the Third Addition to North Shore Oaks to the north plat line of the Second Addition to North Shore Oaks. III.DESCRIPTION OF PROJECT The improvement will ~rovide residential properties with City sewer and water util~ty services. City streets will be reconstructed after utility installation with storm sewers, concrete curb and gutter and bituminous surfacing. Ash Circle and Hampton street have 16 and 11 platted lots, res~ectively, in which several lots are developed with single fam~ly homes having on-site sewage disposal systems and private wells. The unplatted property west of Ferndale Avenue is undeveloped and the property adjacent to Ferndale Avenue will be provided sewer and water utility service. Ash Circle, Hampton street, and Ferndale Avenue from the north intersection with Ash Circle to the north plat lines of the Second Addition to North Shore Oaks will have the streets restored with storm sewers, concrete curb and gutter, and bituminous surfacing. utility line stubs are available to serve the project area on Fisher Avenue b~ the Cit~ park and at the Fisher Avenue and Hampton Street 1ntersect~on. utility lines must be extended 390 feet through the City park in the Third and Fifth Additions to North Oaks to serve Ash circle, Ferndale Avenue, and Hampton Street. A portion of Hampton Street may be served with the utility line stubs on the Fisher Avenue and Hampton street intersection. The drainage district for the 8 inch sewermain through the cit~ park could ultimately serve more than the proposed proJect area. It is estimated that the 8 inch sewermain could serve 176 acres of gross development area. The project area in this feasibility report would have 17.8 acres of gross development area or 10.1% of the total drainage area possible for this sewermain. IV: LENGTH OF PROJECT This proposed project consists of approximately 2,825 lineal feet of sanitary sewer main, 2,850 lineal feet of watermain and 2,650 of street construction and appurtenant work for Ash Circle, Hampton street, and Ferndale Avenue, within the 2nd, 3rd, and 5th Additions to North Shore Oaks. v. FEASIBILITY From an engineering standpoint, this pro~ect is feasible and can be accomplished as proposed and not ~n conjunction with any other project. VI. ESTIMATED COST The following costs were prepared based u~on an Engineer'S Estimate and are subject to change depend~ng on the final design of the project, bids received, and actual work performed. The method of assessment and rate will be determined at the Assessment Hearing. The estimated project cost below is for the installation of sanitary sewer, watermain, and street improvements for Ash Circle, Hampton street and Ferndale Avenue within the 2nd and 3rd Additions to North Shore Oaks and the sanitary sewer and water mains thru the city park within the 3rd and 5th Additions to North Shore Oaks and includes 25% indirect costs: PROJECT COST ...................$442,600.00* * Costs have been estimated without the benefit of soil borings.

The sanitary sewer line in order to serve 140th Street needs to be installed to a greater depth and this extra cost is estimated to be $8,500.00. This cost will be paid for with Trunk System Reserve funds and is deducted from the assessable cost of the project. The cost of the sewer and water mains thru the city park will be prorated according to the size of the project area to the total drainage district area of the 8 inch sanitary sewermain. The project area is 10.1% of the estimated total drainage district area for this sewermain. The assessable cost of these lines is estimated to be $3,592.00. The remaining cost of $31,908.00 will be paid for by Trunk System Reserve funds.
