The summary of nal report was written
by Phl ad, Dwr. F m f-
m Phl ad 916-651-
9663.
1The total cost of the project feasibility study was
estimated to be $67,051. The State of Californias
share of the cost was estimated at $54,545. The naloverall project cost was $60,722. The project came in
$6,328 under budget, with the nal State cost being
$48,216.
2The District estimated the average avoided cost of
water is $140 per acre-foot. The District must work
on managing the subsurface drainage stream, which
is estimated to cost $300 per acre-foot. It is assumed
that 75% of the deep percolation enters the subsur-
face drainage stream. The combined cost savings
resulting from reduction of applied water is therefore
estimated $365 per acre-foot. At an average water
savings of 0.47 acre-feet per acre per year, the cost
is $172 per acre per year. The annual water savings
occurs on a total of 14,500 acres and is estimated to
be 6,815 acre-feet per year.
