Plan of Study - Greeley and Loveland Irrigation System Rehabilitation Feasibility Study

Page 4

Products:
1. A memorandum will be prepared describing the analytical methods and results of the existing facilities
evaluation.
2. A working DSS hydraulic model which will be given to the Company for future use.
3. ECI will give a one-day modeling training program for selected Company personal on the use of the DSS
hydraulic model.
4. A system matrix which will identify problem reaches. The system matrix will be used in Task 4
Alternative Development.

Task 4 - Alternative Development
Objective:
Several alternatives will be developed including structural and nonstructural elements in an attempt to identify
the least costly combination of measures for achieving the study objective.

Methodology:
1. Identify structural and non-structural plan elements.
2, Preliminary evaluate plan elements to determine which are suitable for further analysis.
3. Formulate alternatives using those plan elements which are carried forward from the fIrst two steps.

Products:
1. A memorandum will be prepared describing the methods used in formulating alternatives from the plan
elements. The fmmulated alternatives will be used in Task 5 Alternative Evaluation.

Task 5 - Alternative Evaluation
Objective:
The alternatives identifIed in Task 4 must be evaluated to distinguish the differences between them and to
formulate up to three sound system alternatives.

Methodology:
1, The plan elements will be formulated into system alternatives. The six evaluation factors used by the
CWCB will be used which include the following:
a. description of project outputs or yields;
b, project costs including capital costs, annual costs and cost per unit of output;
c. impacts on the man-made environment, the natural environment, and existing social structure;
d. the financial feasibility of the proposed project as measured by the project sponsor's ability to
repay all reimbursable costs;
e. institutional requirements for project implementation; and
f. any special technical problems which should be taken into consideration.
2. An evaluation of institutional considerations will be undertaken to obtain compliance of governmental
agencies and/or other parties to allow project implementation. Each major institutional considerations
will be described in the study report. The results will be presented in a summary table format indicating
the type of action required,
