<br />City of Elk River <br />Northeast Development Area Optimization Proposal <br />Page 5 of 8 <br /> <br /> <br />a. Assessment of Baseline Demand: <br />i. Evaluate previous studies completed by the City. <br />ii. Assess the City’s existing water demands for current development <br />conditions. <br />b. Water Demand Projections: <br />i. Project the existing, 2045, ultimate average and maximum day demands for <br />the areas to be served based on the planned growth and future zoning <br />classifications. The boundary of the service area to be studied for the water <br />system study will match the service areas identified as part of the sewer <br />study. <br />c. Water Infrastructure Needs Assessment: <br />i. Utilize the City’s water distribution system model in conjunction with the <br />projected demand to plan for infrastructure needs. <br />ii. Provide preliminary transmission watermain sizing recommendations for <br />the development areas based on the maximum day demand. <br />iii. Determine if additional infrastructure beyond transmission watermains <br />(booster stations, pressure reducing stations, water towers, treatment, etc.) <br />will be needed. <br />iv. Develop a planning level transmission watermain alignment to serve the <br />planning areas. A single alignment will be prepared using ArcGIS Pro <br />Software and will identify the following: recommended transmission <br />diameters and other recommended infrastructure. One iteration per <br />alignment is anticipated upon initial City review. <br />4. Opinion of Probable Project Cost Development: <br />a. Prepare planning-level Opinion of Probable Project Cost for the proposed sanitary <br />sewer and water system improvement options. Normalize the cost to a “per unit” <br />basis considering the anticipated number of residential equivalent units to be <br />served by the revised service area boundary. <br />5. Feasibility Study Amendment Report: <br />a. Prepare a draft report summarizing the findings and recommendations of the <br />study. The report is intended to be an update to the previous service area <br />expansion report. Review the draft report with City staff. <br />b. Prepare a final report based upon the City’s review comments. <br />c. The following GIS figures have been identified to be included in the report: <br />i. Existing sanitary sewer system highlighting City-Owned infrastructure <br />(interceptors, meters, and lift stations), sewersheds, and the development <br />areas to be studied. <br />Page 104 of 204
