The published physical information will include construction drawings <br />of the existing facilities. Researching available information witl develop an understanding of the <br />environmental and water rights issues. <br />Methodology: <br />1. Available water rights information from the Company will be reviewed and tabulated. <br />2. Existing twafoot contour maps will be obtained from the City of Loveland and the Company.

Identify structural and non-structural plan elements. <br />2. Preliminary evaluate p(an elements to determine which are suitable for further analysis. <br />3. Formulate alternatives using those plan elements, which are carried forward from the first two steps. <br />Products: <br />l. A memorandum will be prepared describing the methods used in formulating a(ternatives from the <br />plan elements. The formulated alternatives will be used in Task 4. <br />� <br />. <br />L� <br />D:�PROJECTS\RYAMRAYN. DOC <br />
