<br />- 11 - <br /> <br />. <br /> <br />Formulate a number of alternatives in each basin to address the water supply issues and problems <br />identified in Tasks 7, 8 and 9. A methodology or rationale for the formulation of alternatives will be <br />developed to include near-term and long-terrn scenarios. <br /> <br />Alternatives will include both structural and non-structural elements that could be used individually <br />or in combination. Extensive use should be made of exiting information in identifying structural and <br />non-structural elements before new concepts are developed. <br /> <br />Non-structural measures will include but are not limited to: efficiency in water use, water rights <br />transfers or exchallges, water leasing, improved water management techniques, revised operations of <br />existing systems and new or revised institutional arrangements which have the potential to reduce <br />demands and/or increase supplies. <br />Structural elements will include but are not limited to: new water storage reservoirs, enlargements of <br />existing reservoirs, improvements to existing reservoirs to remove dam safety restrictions, trans- <br />basin diversions, regulating storage, pump-back schemes, grouudwater utilization and water reuse <br />facilities. Hydropower development will be ~onsidered where it appears to have significant potential <br />to repay some portion of the costs of other proj ect purposes. <br /> <br />lOa. Select structural and non-structural plan elements for suitability in formulating altematives. <br /> <br />lOb. Develop a methodology or rationale for the formulation of alternatives. <br /> <br />. <br /> <br />I Dc. Develop altematives using appropriate combinations of structural and non-structural <br />elements. <br /> <br />Task 11 - Evaluation of Water SUllply Alternatives <br /> <br />Alternatives will be evaluated in a multi-step screening process. Existing computer models and <br />decision support systems should be utilized to the maximum extent possible. <br /> <br />The first step in the screening process will be the identification of "fatal flaws" in any particular plan <br />element so as to eliminate tllat item from further consideration. Subsequent screening steps will <br />consist of more detailed analyses. Alternatives may be reformulated and reevaluated in an iterative <br />evaluation process. <br /> <br />An evaluation procedure will be developed using a computer matrix or matrices so that each <br />alternative may be easily compared with all other alternatives uuder consideration. The procedure <br />will have the capability of analyzing alternatives while varying the values or weights used in the <br />evaluation. <br /> <br />The final step in this task will be the selection of one or more preferred alternatives for each basin. <br />Selection will be accomplished by: public input at local and basin meetings, recommendations of the <br />study advisory groupe s) and review by the Colorado Water Conservation Board. <br /> <br />. <br /> <br />II a. Develop a methodology for the evaluation of alternatives to describe the process and the <br />evaluation factors to be used. Some suggested evaluation factors are: <br /> <br />Physical and legal availability of water uuder average-year and dry-year conditions, <br />Flood Protection. Water Project Planning and Financing. Stream and Lake Protection <br />Water Supply Protection. Conservation Planning <br />
