Water Supply Reserve Account -Grant Application Form <br />Form Revised May 2007 <br />II. Task 2 <br />Description of Work: Infrastructure Assessment of Summit Irrigation Company Facilities <br />Methodology: The work will include a field evaluation and condition assessment of the infrastructure <br />including dams, canals, turnouts, siphons and diversion structures. A designated list of stakeholders will be <br />interviewed for historic perspective and background on current operating procedures. All known historical records <br />pertinent to the irrigation company will be compiled including State Engineer documentation on the dam design and <br />construction, dam safety reports, diversion records, irrigated acreage, maintenance records, capital expenditures on <br />0&M. Current conditions would also be compared to the normal standard of care and practice expected in this <br />region. <br />A preliminary geotechnical exploration of the Summit Reservoir dam will be performed. The exploration will take a <br />series of boreholes along the centerline of the dam axis where accessible for classifying the soils used in the original <br />construction and to determine foundation conditions underlying the dam. <br />A bathymetric survey will be made of the reservoir area to collect underwater topographic data from the reservoir <br />bottom. This information will be used to calculate the current active capacity of the reservoir and for earthwork <br />calculations on recommended rehabilitation repairs that may be necessary to bring the dam into compliance with <br />current safety standards. The underwater calculations will be used to compare area-capacity curves from historic <br />information to present day conditions to assess siltation buildup and the associated fixes that may be needed to restore <br />active storage. The dam and saddle dike will also be surveyed. Facilities such as outlet works and spillways will be <br />mapped. The mapping will be used to prepare quantity and construction cost estimates for rehabilitation work on the <br />facilities. <br />Preliminary engineering concepts will be identified on rehabilitation work needed for the infrastructure. Alternates <br />on how the Summit Irrigation system can be integrated into the MVIC system will be identified. A preliminary <br />opinion of probable cost will be developed for a minimum of three (3) alternates and a maximum of five (5). Current <br />construction costs will be used to develop a present day cost structure. All alternates would be mapped using a GIS <br />base. A preferred alternate will be identified. <br />Major Deliverables: An engineering report will be produced that summarizes the findings outlined in the <br />methodology. The report will identify the known risks and liabilities that might be associated with the infrastructure <br />and capital costs that would be incurred to bring the infrastructure into compliance with current standards. It will also <br />identify from a technical viewpoint opportunity for efficiency that may exist with the two systems working together. <br />The results will give a second GO-NO GO decision point on whether or not to continue pursuing the concept of <br />merger or acquisition. <br />Future proposal for Task 2 (if warranted by Task 1) - $127,300 <br />The project team will include Mike Applegate, PE; Tara Schutter, PE; Jack Byers, PE; Craig Ullmann, PE; Michael <br />Peel, EIT; and Matt Young, EIT. <br />7
