Ms. Rachel Juba <br />April 14, 2025 <br />Page 5 <br />Preliminary Engineering <br />WSB will prepare concept plans for the corridor typical sections and intersection improvements <br />as well as cost estimates for the different alternatives. This task will also include a cost and <br />funding analysis. <br /> <br />5. Water and Sanitary Sewer Study <br />Water Demand Projections <br />WSB will calculate the projected water demands for each of the three (3) development <br />scenarios. Additionally, WSB will review the projected water demands against the planned <br />water supply, storage, and distribution capacity in the Comprehensive Water Supply Plan, <br />identify any additional improvements, and prepare cost estimates for those improvements. <br /> <br />Sanitary Sewer Study <br />WSB will complete a broader sanitary sewer study, which will include how the 165th Street <br />area would be served in two trunk sanitary layout alternatives including (1) the current <br />Comprehensive Plan, (2) serving District O only via its trunk sewer and diverting Ultimate <br />District U flows north through District Q. Each of the two trunk sanitary layout alternatives will <br />take into account the highest wastewater flow from the three (3) development scenarios to be <br />conservative. The second trunk sanitary layout alternative will include the sewer sizing and <br />conceptual layout for that alternative. The results of the sanitary sewer study will be <br />summarized in a separate technical memorandum including figures and cost estimates for each <br />alternative. <br /> <br />COMPENSATION <br />The estimate to complete the work described herein is $167,324 to be performed on an hourly <br />basis, as summarized below. Invoicing will be monthly in accordance with our current (2025) Rate <br />Schedule. <br /> <br /> <br /> *assumes 3 development scenarios. If additional development scenarios are added, <br /> a fee amendment will be necessary. <br /> <br />SCHEDULE <br />Work on the project will start upon acceptance of this agreement and authorization of the City. <br />AUARs generally take approximately 9-12 months to complete, from authorization of work through <br />adoption of the Final AUAR. An estimated schedule is attached, and a detailed schedule can be <br />developed following contract authorization. If the project goes on hold for more than ninety (90) <br />days during our contracted work, additional fees may be required. <br /> <br />ACCEPTANCE <br />This letter represents our entire understanding of the project scope. If the City of Hugo agrees with <br />the scope and fee defined herein, WSB will start work outlined in this proposal per our 2025 Rate <br />Schedule. <br /> <br />If you have any questions about this proposal, please feel free to call me at 612.360.1320 or email <br />at aharwood@wsbeng.com. This fee proposal is valid for ninety (90) days from the creation date. <br />TASK DESCRIPTION COST* <br />1 Meetings and Project Management $18,550 <br />2 Develop Land Use Scenarios (Landform) $25,124 <br />3 AUAR and Mitigation Plan $63,850 <br />4 Traffic Study $38,800 <br />5 Water and Sanitary Sewer Study $21,000 <br />TOTAL $167,324
