ACTION: 7:{ 2izf�
TO: The Honorable City Council /
FROM: Kenneth C. Gilbert, Director of Public Works C
DATE: April 19, 1996 (Council Meeting 5-1-96)
SUBJECT: Consider Authorizing Recordation of the Notice of
Completion for the Installation of a Pump and Related
Equipment for Water Well 13 at Arroyo Vista Community
Park
DISCUSSION
A. Background
1. The property conveyed to the City by Urban West Communities
for Arroyo Vista Community Park included two existing water
wells used in the past to supply irrigation water to the
agricultural uses on the property. 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 called for the construction of an
irrigation system supplied by these wells.
2. These water wells were in excess of forty (40) years old.
Accordingly, the City Council authorized staff to proceed
with a water well rehabilitation program which included the
following improvements:
- the removal, inspection and evaluation of Water Well #2;
- based on that analysis, it was decided to replace Well #2
rather than attempt to rehabilitate it;
- the destruction and capping of water well #2;
- the replacement of the pump motor for Well #1 with a new
40 HP submersible pump;
- the preparation of a design and the award of a
construction contract for the drilling of a new Well #3;
- the subject project to install the pump, piping and
related equipment required to make Well #3 operational.
3 . In December of 1994 the City Council accepted the
improvements and authorized the recordation of a Notice of
Completion for the drilling of Water Well #3 at Arroyo Vista
Community Park.
4. In September of 1995 the City Council approved the plans and
specifications for the subject follow-up project to install
the well pump and related equipment. Upon completion of
the subject project, the water well rehabilitation program
will be completed.

5. On December 20, 1995, the City Council awarded a contract
for the subject project. That work is now completed.
B. Purpose
The primary purpose for using the on-site water wells is cost
effectiveness. A comparison of the estimated cost of well
water and domestic water is summarized as follows:
Domestic Water City Water
Description Service Costs ($) Well Costs ($)
Calleguas Municipal Water 70 ,000 0
District Connection Fees
Water Works District #1 19,000 0
Capital Connection fees
Water meter installation 1,500 0
charges
Water usage per year 30,000 1,000
Phase I (33 acres)
Water usage per year 60,000 2 ,000
Total Park (69 acres)
Water well maintenance 0 1,000
and operation (electrical
energy, oil, etc. )
C. Project Description
The subject project generally consists of the following:
• installation of a pump in the newly drilled Well #3 ;
• installation of piping and the connection of Well #3 to the
irrigation supply control facilities located at Well #1;
• installation of electrical service and equipment; and,
• installation of control systems.
D. Project Status
The construction of the subject project has been completed.
The work has been tested and accepted. The upgrading of the
irrigation supply system for Arroyo Vista Community Park has
been completed. Through these wells, the park now has a
primary and a back-up source of irrigation water, without the
need of an expensive connection to the domestic water supply
for the City. It is the intent of the Parks Maintenance staff
to alternate the use of these two wells to assure that both are
in good working order.

E. Future Expansion of the Irrigation System
Designs are now underway for the construction of two additions
to the irrigation water system supplied by these wells. The
first would extend the system to irrigate the turf area now
being developed just east of the existing park improvements,
which is to be used for youth football. The second will extend
the irrigation system across the Arroyo Simi, inside the Arroyo
Vista Community Park Pedestrian/Equestrian/Bicycle bridge to
serve the north side of the bridge and Campesina Park.
F. Fiscal Impact
1. Total Contract Cost Summary: The total final construction
costs for the subject project are summarized as follows:
