have to be purchased and reclaimed after the material is removed. If" the
land for the enlarged reservoir is not purchased initially, the additional
cost would have to be incurred during the enlargement.

The most cost effective alternative is to build the reservoir at the
increased size initially. The initial cost--for the five miles of pipeline
to the treatment plant represents almost 12 percent of the project
construction cost. For a smaller proj ect, the total pipeline cost would
remain the same, but the percentage of the total project cost would be much
higher. The same applies to the initial costs for road and pipeline
right-of-way and for access road improvement.

ESTIMATED CONSTRUCTION COST

Project costs were determined by estimating the quantities of various
materials required for each feature and applying an associated cost. Where
possible, unit prices were used rather than lump sum prices. The unit
prices are based on averages of bids received for similar projects
constructed by Western Engineers, Inc. and others during the last 5 years.

Costs for the dam and appurtenances came from bid abstracts from
Taylor Dra~v Dam near Rangely, Colorado, which was bid in July 1982;
Monticello Dam near Monticello, Utah, bid in April 1984; and
Smith-Moorehouse Dam in northern Utah, bid in September 1984. Both the
Monticello Dam and Smith-Moorehouse Dam are above 7,200-feet (MSL) and are
over 120-feet high. All three projects are close to small towns with
limited services. In order to estimate unit costs for similar construction
items found in the Snowball Dam, the average unit price from the three
projects for each bid item was determined. The high and low bidders were
then excluded and a new average determined. The values from the three
projects were then averaged and used as the unit price for determining
Snowball Dam's cost. Table 5.2 shows the unit costs for the Snowball Dam,
as well as the projects used to compile the unit prices. The averages of
the unit prices for the other dams are shown on the table.
