Utilities Director Utilities Engineer 7"
SUBJECT: Contract for Well Development - Phase I
CAO Recommendation:
Approve plans and specifications and authorize staff to
advertise for bids
Background:
Groundwater was utilized by the City of San Luis Obispo until
1942. At that time water was first received from the Salinas
Reservoir near Santa Margarita. The consumption of groundwater
was slightly more than 1,000 acre feet a year but was
apparently discontinued due to the superior quality of the
Salinas Reservoir.
Groundwater is a part of the Draft Water Management Plan and is
a Major Objective of the 1987-89 Financial Plan. The
Groundwater Location and Development Budget allocated $50,000
for the study phase in 1987-88 and $200,000 is budgeted for
design and construction in 1988-89. This is as requested by
the Council at its meeting of February 24, 1987.
A contract for the study phase of the Groundwater Location and
Development project was awarded to John L. Wallace and
Associates which provided for the drilling of test wells as a
part of their work. The information obtained from the testing
indicates that four of these test wells show promise in
providing water for the City of San Luis Obispo.
The two best wells for water quality were the Pacific Beach
well and the Fire Station #4 well. Both of these wells will be
developed under this contract to supplement our domestic water
supply. Their anticipated production is 500 acre feet a year.
The Mitchell Park well and the Old Resrvoir #1 well will be
equipped with pumps under this contract. It is anticipated
that the Mitchell Park well will be connected to the irrigation
system. The mitigation called for under the environmental
review was to limit the use of the Mitchell Park well and the
Old Reservoir #1 well while studies were conducted to determine
their effect on the flow in San Luis Obispo Creek. The Phase
IV and Phase V report from John L. Wallace and Associates will
provide the City Council with the alternates for further well
development. The intent is to return with a Phase II Well
Development contract at that time.
The environmental review has been completed by the Director of
Community Development. Limited use of the Mitchell Park well
and the Old Reservoir #1 well were a part of the mitigation.
This matter will be addressed in the final reports from John L.
Wallace and Associates. ..�_
