8. FEASIBILITY AND RECOMMENDATION <br />This study evaluated the infrastructure needed to serve the study areas shown in Figure A1. If sanitary <br />sewer and water service is extended to these areas, it is recommended to follow the infrastructure layouts <br />shown in Figures A9, A13, A19, A21 and A22 in AppendixA. Since the study area is mostly undeveloped, <br />installation of water and sanitary sewer utilities will be driven by development. The total estimated <br />infrastructure cost needed to serve the study areas over the next twenty years and beyond is $28,478,000 <br />for the sanitary sewer system and $75,612,000 for the water distribution system. Detailed cost breakdowns <br />are shown in Appendix B. Overall, it appears that extending water and sewer services to the expansion <br />areas could be feasible as long as leapfrog development is avoided, the areas are not served <br />simultaneously, and the cost is divided over various funding avenues. Promoting leapfrog development will <br />require a considerable amount of infrastructure to be installed initially which could place the City and the <br />ERMU at financial risk if subsequent development is slower than anticipated. Additionally, it is <br />recommended to extend water and sewer service concurrently as this can reduce capital costs. <br />Feasibility Report <br />Northeast & Northwest Urban Service Area Expansion Study <br />City of Elk River, MN <br />WSB Project No. 020010-000 <br />Page 31 <br />
