Chapter XIII - Conclusions

Chapter XIII - COlllclusions

The Districts have made the decision to construct a reservoir capable of storing
approximately 8,850 acre-feet of storage. The reservoir will provide carry-over storage for their
existing C-BT water in the future and during droughts, reduce the reliance on C-BT water delivery
infrastructure, and provide supplies so that water can be efficiently and immediately delivered to the
CLFP in response to customer demands.

The Districts' decision to pursue an 8,850 acre-foot reservoir instead of a 5,200 acre-foot is
based on the following considerations:

;.. A smaller reservoir may not be adequate to protect against long term drought
conditions;

;.. Minimize conflicts with property owners whose lands would be acquired for the
smaller reservoir and then again at a later date to accommodate a future enlargement;

;.. Enlarging the reservoir by raising the dam at a later date would be difficult due to the
inundation of embankment material necessary for the enlargement;

;.. Constructing the larger reservoir would prevent the Districts from having to repeat
the permitting requirements again in the future.

The project will cost approximately $21,600,000 or $2,440 per acre-foot without loan
interest and approximately $3,330 including interest for LTWD' s portion of the storage ,md $3,350
for CWCWD's portion of the storage. This is a relatively reasonable storage cost and is less
expensive than other alternatives available to the Districts.
The project is expected to move forward without any significant issues. Construction is
scheduled to begin around October 1, 2005 and last for approximately one year.
