Box 2007 7 Oak Park Heights, MN 55082 Re: Screaton Annexation Our File No. 55 Gen Dear Mr. Robertson: We have reviewed the proposed annexation of a 48.9 acre parcel of land in Baytown Township lying west of State Highway 5 and south of 55th Street as it relates to providing utility service. At the present time, sanitary sewer and water main stubs exist on the north side of 58th Street, 500 feet east of State Highway 5. To provide service to the Screaton parcel would require the extension of the sanitary sewer along the north side of 58th Street, with the crossing of Highway 5 to be undertaken by jacking under this roadway. The sewer would then be continued to the south, parallel and adjacent to Highway 5. The Screaton property is at an elevation which will require the installation of a sewage lift station to pump the waste through a force main with discharge to the gravity sewer described above. While we do not know the type or extent of development proposed, it was assumed that a 150 gallon per minute lift station with a 6 -inch diameter force main would be used for cost estimating purpose. This size could possibly be reduced in final design for the Screaton parcel only. A 12 -inch diameter water stub also exists on the north side of 58th Street at 500 feet east of Highway 5. This 12 -inch diameter water main would be extended westerly along 58th Street with a jacked crossing of Highway 5. The main would be extended with an 8 -inch diameter pipe parallel and adjacent to Highway 5 to across 55th Street which is the Screaton site. A detailed cost estimate has been prepared for each of the facilities described and is attached as an Appendix to this letter. The costs are summarized as follows: Item Estimated Cost Sanitary Sewer $ 67,400.00 Lift Station and Force Main 178,200.00 Water Mains 90,300.00 Total Project Cost $335,900.00 2335 West Highway 36 • St. Paul, MN 55113 • 612 - 636 -4600 'r • • Mr. Mike Robertson June 13, 1995 City of Oak Park Heights Re: Screaton Annexation Page -2- The cost estimates are based on unit prices anticipated for the 1995 construction season and include a 25 percent allowance for contingencies, engineering, fiscal and administrative fees. The above costs are for physically providing service to the parcel and do not include any internal site systems to serve individual sites or parcels. In addition to the costs shown above, the City would also require payment of $2,100.00 per acre, which is the standard charge for the water supply and storage elements of the City's water system. To determine the feasibility of the utility extensions, the costs estimated herein were compared to charges collected within the City of Oak Park Heights for trunk service. This comparison is shown in the following tabulation: Item Cost Estimate Screaton City Std. Sanitary Sewer System $245,600.00 $5,025.00/ac $2,110.00 /ac Water Distribution System 90,300.00 1,845.00/ac 1,570.00/ac Water Supply & Storage 102,700.00 2,100.00 /ac 2,100.00/ac Total Costs $438,600.00 $8,970.00/ac $5,780.00/ac With the rather substantial cost associated with jacking the sewer and water mains under Highway 5, coupled with the need for a sewage pumping station and long force main, it is felt that the cost to serve this small 48.9 acre site is excessive. The costs could be reduced on a per acre basis if additional land which could be served by these same improvements were included in the project and in the annexation. As an example, if the 91.1 acres of commercially developing land known as the "Kern Center" lying between Highway 36 and 55th Street and from Highway 5 westerly to the large ravine area were included, services could be provided using the City's standard area and connection charges. With the need for some major improvements to serve the Screaton site, it may not be feasible to provide service to such a limited area. If annexation is still contemplated, it should be contingent upon the owner executing a Developer's Agreement guaranteeing payment for all of the costs associated with the extension of public services.
