SUBJECT: Consider Authorizing Recordation of a Notice of
Completion for the Drilling of Water Well 13 at Arroyo
Vista Community Park.
The land which was conveyed to the City for the development of
Arroyo Vista Community Park included two existing water wells [Well
#1 and Well #2] which, in the past, had been used for agricultural
irrigation (see Exhibit 1 for well locations). Although the water
extracted from these wells is high in Boron and thus not suitable
for drinking, it was determined that this ground water could be
used to provide irrigation water to the park. The design for the
park irrigation system included provisions to utilize these water
wells.
These water wells are in excess of forty (40) years old.
Accordingly, the City Council authorized staff to pursue a number
of steps necessary to upgrade these wells. Those efforts include
the following:
1. the removal, inspection and evaluation of Water Well #2;
2. based on that analysis, it was decided to replace Well #2 rather
than attempt to rehabilitate it;
3. the destruction and capping of water well #2 (recently
completed);
4. the selection of Fugro -West, Inc. to prepare design plans and
specifications for the drilling of a new Well #3;
5. approval of plans an authorization to advertise for bids for the
drilling of Water Well #3; and,
6. the award of a contract for this project.

A. Well Drilling Contract
In August of this year the City Council authorized staff to
advertise for bids for the drilling of Water Well #3 at Arroyo
Vista Community Park. In October the City Council awarded a
contract for this work to Midway Drilling & Pump, Inc.. The
location of the project is indicated on the map attached as
Exhibit 1.
B. Final Project Cost
The drilling of the new well is now completed. The bid amount
for the project was $42,444.77. The final construction costs
was slightly more, at $42,799.77, due to differences between the
engineer's estimated quantities and the final quantities
required to complete the project.
C. Well Water Production Results
One element of the work required for the well drilling contract
was the test pumping of the well. The results of that test
pumping indicated that the maximum ground water production for
this new well is over 700 gallons per minute (gpm). This amount
far exceeded the minimum requirements of 350 gpm for the
irrigation demands of Arroyo Vista Community Park. This new
well will be able to amply 2provide for the future irrigation
needs of the park.
D. Future Efforts
With the completion of the drilling of the new well and the
determination of the well water production characteristics of
this well, the City's well design consultant engineer has been
directed to proceed with the design of the well pump and related
equipment. When completed that design will be modified by staff
to include the following elements:
• the installation of the water line connection to the existing
irrigation system;
• the installation of a new electrical service; and
avpwel5
the relocation /extension of the control circuit for the new
well.

E. Well Pump Project
It is anticipated that the design for the installation of the
pump and related improvements necessary to activate Well #3 will
be completed within two months. When that design package is
completed, the project will be brought back to the City Council
for approval and authorization to advertise.
RECOMMENDATION
It is the recommendation of staff that the City Council take the
following actions:
1) Accept the work as completed;
2) Instruct the City Clerk to file the Notice of Completion;
and,
3) Authorize the release of the retention upon acceptance of the
Work as complete by the City Manager and clearance of the
thirty-five (35) day lien period.
