COUNCIL AGENDA REPORT �"
FROM: William T. Hetland
Utilities Director
SUBJECT: Groundwater Development
CAO RECOMMENDATION:
Receive and file report on Status of Phase I Well
Contract, and adopt resolution approving amendment to
groundwater study contract with John L. Wallace and
Associates, for the development of Phase II
Groundwater Wells.
BACKGROUND
The City of San Luis Obispo relied primarily on groundwater until
the early 1940s when the Salinas Reservoir was developed. In the
1960s the Whale Rock Reservoir was added to the City supply. The
surface supplies were preferred because of aesthetic reasons.
As the City began reaching the maximum yields of its reservoir
supplies, it once again began to look at groundwater as an
additional source. The firm of John L. Wallace and Associates, in
conjunction with Timothy Cleath, Hydrologist, was retained to
perform a groundwater study in December 1987. Their first report,
"Groundwater Study Survey of Resources and Constraints Analysis",
was completed in March 1988. This report reviewed historical
groundwater data and identified a test drilling program. In August
1988, John L. Wallace and Associates submitted the results of the
drilling program in its report, "Groundwater Study - Exploration
Results". This report outlined drilling loops, test pumping and
water quality analysis. It also identified four sites for
development based on the exploration work and previous site
constraint analysis. In October 1988, Council approved plans and
specifications for Well Development - Phase I, and awarded the
contract in December 1988.
A. Status of Existing Phase I Groundwater Contract
The City has under construction its Phase I Groundwater contract.
The contract is for the construction and installation of four wells
that will tie into the city system. The well locations are as
follows:
1. Pacific Beach School
2. Fire Station No. 2
3. Mitchell Park
4. Reservoir Canyon
In conjunction with our existing Laguna Golf Course well, these
wells will produce up to a total yield of 665 acre feet, based
on estimates by John L. Wallace and Associates. The City has used
a more conservative figure of 500 acre feet. The wells are to be
completed and on line by the end of March.

B. Development of Phase II Groundwater Wells
In light of the City's current water situation and the long time it
traditionally takes to implement a project, staff proposes that
John L. Wallace and Associates be retained to expedite Phase II of
the City's well development.
Attached is a copy of Contract Amendment #2 Groundwater Study from
John L. Wallace and Associates. This contract amendment is for the
complete development of additional wells to serve the city. Seven
(7) locations have been identified for potential groundwater wells:
1. Immigration Services Building; frontage road
2. Auto Parkway
3. Dalidio Property
4. Dalidio Property
5. Pacific Beach Well, No. 2
6. Anholm Well Site
7. Ferrini Property; Highway 1
The engineer will be responsible for siting the specific wells,
C ; development of the drilling specifications, drilling observation,
and construction design and management. At the completion of the
project the well will be operational.
It is estimated that these additional sites will generate 2000-2500
acre feet of water. Between the Phase I and Phase II development,
the City is reaching the maximum amount of water that the
distribution system can consume in the Laguna Lake/South Higuera
area.
The key emphasis for this contract is expediting well construction
as soon as possible. Every effort is being made to bring the wells
into production and connect them into the city system in as short a
time as possible. The expected schedule for construction of the
wells under this contract is as follows:
a. Contract amendment executed March 15, 1989
b. Site review and informal well specifications
completed, well drillers contacted, bids
solicited, contract awarded, drillers'
scheduled to begin work March 31, 1989
c. Drilling completed, well head facilities
designed *April 30, 1989
d. Informal bids solicited, wells equipped,
and tied into City distribution system May 31, 1989

page 3
* Wells' design begins as soon as a decision is made on
acceptability of site, production and quality. Temporary use of
existing agricultural wells on Dalidio property could occur more
quickly than proposed schedule.
John L. Wallace and Associates is being recommended for this
additional work because they have performed the previous
groundwater work for the City and, as such, are most knowledgable
of our situation. This is, therefore, a sole source contract which
is acceptable under the City's purchasing control procedures PC
402-1.
FINANCIAL IMPACT
Because a number of decisions will be made in the field and the
contract is being performed on an expedited basis, it .is
recommended that the contract be a time-and-materials contract with
a maximum not-to-exceed amount. It is estimated that the cost will
not exceed $360,000. The City currently has adequate funds within
its water fund balances to cover the cost of these additional
wells.
CRECOMMENDATION
Adopt resolution approving amendment to contract with John L. i
Wallace and. Associates for the Development of Phase II Groundwater
Wells.

Subject: Contract Amendment Number 2; Groundwater Study;
City of San Luis Obispo
Dear Mr. Hetland:
Please find attached, Amendment Number 2 to our contract executed
by the City on December 7, 1987 and as discussed in our recent
meetings concerning the City's desire to continue with the
groundwater exploration and development program.
The previous phase of this program is rapidly being completed
with the installation of four wells in addition to the City's
previously completed well at Laguna Lake Golf Course. We
estimate that the first phase of the program will bring to the
City a total of 665 acre feet of additional water per year. The
attached amendment provides for continuing with a second phase of
this program in order to increase the potential for groundwater
production to a total of 2000 to 3000 acre feet per year.
We appreciate the assistance that you and your staff has provided
to us and we look forward to rapidly completing the second major
phase of this program for the City.
If you have any questions or comments about this amendment,
please do not hesitate to call me at your convenience.
