" .' .' cc ,. U": ,- ~ Alternatives were developed by first identifying potential project elements or components. Next, the identified project elements were subjected to a screening analysis to eliminate less suitable items from further consideration. Finally, the individual elements which survived the screening process were combined in alternative projects using the following plan formulation criteria: 1. Alternatives were developed to illustrate the potential costs and yields for a wide range of development. 2. The maximum project considered was similar to the system recommended in the 1985 Rescoping Study, 3. Alternatives were formulated to improve and expand existing facilities, to develop new sources of water or to do both.. _- .. 4. Alternatives were formulated to be generally complementary such that a larger project could be developed in stages starting with one of the smaller alternatives. The Phase One study was a comprehensive reconnaissance investigation resulting in six final alternatives ranging in capital cost from $1.9 million to $20.6 million. The need for low.cost methods of improving water supplies resulted in the selection of an alternative serving the Norwood-Redvale area with a capital cost of $2.9 million composed of a combination of structural and non-structural improvements. PHASE TWO STUDY Phase Two of the study is currently underway and consists of investigations of the feasibility of the structural improvements and implementation of the non-structural improvements. The Phase Two work is a cooperative effort involving State, Federal, and private sector components. The lead agency is the CWCS with assistance provided by the USSR, the Soil Conservation Service (SCS) , the County Extension Service, and the local ditch companies. The lead technical role is provided by Boyle Engineering Corporation under contract with the CWCS. 5
