City of Idaho Springs

1) Approval of a 2 year Emergency Loan in amount of $130,000 to make
immediate repairs the City's nlW water intake structure, and to the City's
Chicago Creek Reservoir.

2) Approval of a Construction fund Authorization in amount of $1,500,000

BACKGROUND

The City of Idaho Springs (located in Clear Creek County), has applied for an Emergency Loan
to make repairs to the City's raw water storage and diversion structures. The City has also
applied for a Construction Fund Authorization to undertake major rehabilitation of those same
structures. They are requesting a $130K Emergency loan, and a $1.5M Authorization from the
Construction Fund.

Emergency Loan: The City's raw water intake structure was damaged during high runoff in
the spring of 1995, and can not be repaired. To get water to the treatment plant it was
necessary to construct a temporary pipeline, and to place concrete blocks in the stream to form
a diversion. During the winter months the low flows will make it very difficult to divert water
out of the stream for drinking water purposes. The City needs to make emergency repairs as
soon as possible, at a cost of approximately $IOOK.

The City's raw water reservoir (Chicago Creek Reservoir) recently experienced a failure of the
outlet valve. The valve stuck in the open position, and all water drained from the reservoir.
The City needs to repair the valve as soon as possible, and to back-fill a large depression in the
reservoir basin at the upstream toe of the dam. These emergency repairs need to be completed
to store water for use in the winter months. The estimated cost is $30K.
