iNTRODUCTION Th~ City has received a petition from Polka Dot Dairy for the development of an approximate 6.4 acre parcel location on the northwest corner of the intersection of County Road gl 16 and Trunk Highway #47. The property is proposed to be developed into three lots. The southernmost will be utilized for a Super America service station. A petition for the extension for sewer and water improvements to this property was received by the City Council on May 23, 1995. This report is intended to examine the feasibility of the project, determine the estimated costs and assessments for the extension of municipal sewer and water utilities. Appendix A contains an exhibit illustrating the project area. DESCRIP.TION OF EXISTING CONDITIONS The parcel proposed for the improvement is located on the northwest comer of Trunk Highway #47 and County Road #116. At the present time, water is available a distance of 350 feet north of the: site within the right-of-way of 142nd Aver~ Je. Sanitary sewer is available a distance of approximately 250 feet east of Trunk Highway #47 through the rear of the Rivers Bend Plaza mall. DESCRIPTION OF IMPROVEMENTS It it proposed to extend the watermain southward along the western right-of-way of Trunk Highway #47 for a distance of approximately 1,100 feet to the northwestern corner of the intersection of County Road gl 16 and Trunk Highway #47. Sanitary sewer will be extended to the subject parcel from an existing manhole located 250 feet east of Trunk Highway #47. The sewer will be extended westward and jacked under Trunk Highway #47 to the northwest corner of Trunk Highway 4/47 and County Road #116. From there it will be extended northward a distance of approximately 700 feet. The utilities are anticipated to be very near the water table and dewatering may be required. Three six-inch service laterals will be stubbed off of the sewer main for each of the anticipated three lots as will a four-inch water service. Following construction, turf shall be restored with four inches of topsoil, seed, fertilizer and mulch. Disturbed pavements shall be neatly saw cut and replaced in-kin& ESTIMATED PROJECT COST The estimated construction and project costs are summarized in Table 1. Detailed estimates are included in Appendix B. It should be noted that both sewer and water need to be extended 300 to 350 feet to reach the subject property. However, it wSll also be necessary to extend both sewer and water from the northwestern corner of the subject property westward a distance of 400 to 450 feet to-service the parcel to the west in the future. Therefore, it is proposed that the only costs attributable as trunk costs on this project should be limited to the jacking required under Trunk Highway #47. Table 1 also indicates overhead costs at 30% of the construction cost as an allowance for engineering, legal and other indirect costs. The allowance is comprised of the following components with the final cost of these items determined by actual costs: Engineering 10% Staking and Inspection 7% Fiscal and Legal 3 % Administration 5% Contingencies . 5% TOTAL 30%
