BVALlJMIaI OF ALTBBIIA'rIVBS <br /> <br />Two sets of evaluation factors, monetary and non-monetary, were used in <br />evaluating the eight preliminary alternatives in Phase I of the study. The <br />monetary factors consisted of: (1) initial investment costs, (2) benefit-cost <br />ratios, (3) net direct economic benefits and (4) cost effectiveness expressed <br />in terms of project costs per kilowatt of installed generation capacity and <br />costs per acre-foot of storage. The non-monetary factors used were: (1) <br />geologic conditions, (2) impacts from inundation at each reservoir site and <br />(3) increased water yield of "new water" developed as a result of project <br />implementation. These evaluation factors were selected in accordance with the <br />study mandate which was to assess the engineering and economic feasibility of <br />a potential Cache la poudre Project. <br /> <br />At the completion of Phase I, the CWCB selected Alternatives 1, 2, 7 and B <br />for further analysis in Phase II of the study. The four selected alternatives <br />represent two important development concepts. Alternatives 1 and B represent <br />single reservoir systems which provide storage pr imar ily for conservation <br />purposes (agricultural, municipal and industrial water demands and the <br />improved management of existing water supplies).
