SUBJECT: APPROVE PLANS AND SPECS FOR LAMPSON
AVENUE WELL, PHASE II WELL EQUIPMENT AND
SITE IMPROVEMENTS AND LAMPSON AVENUE
WELL, PHASE II -WATER TRANSMISSION MAIN AND
GRAVITY SEWER, PROJECT NO. WT0903
SUMMARY OF REQUEST:
The City Council is asked to approve the plans and specifications for Lampson
Avenue Well Phase II -Well Equipment and Site Improvements and Lampson
Avenue Well Phase II -Water Transmission Main and Gravity Sewer, Projects
No. WT0903 and authorize staff to solicit for bids.
BACKGROUND:
This multi-year project involves construction of a new water well on property north
of Lampson Avenue. The project includes several elements such as drilling a pilot
hole, casing installation, well development, step drawdown, long term aquifer
testing, mechanical, structural, electrical, controls, emergency power, disinfection
facilities, and major sewer and water line upgrades in College Park East. This
project will add another source of water to the City's system. It will be the only
source located north of the 405 Freeway.
The City has recently completed construction of the Lampson Avenue Well Phase I
Project. This project consisted of drilling the well hole along with development and
testing. City Staff decided to break up Phase II into two separate contracts under
project No. WT0903. The first consists of building the housing and on-site work.
This includes the building, motors, pumps, electrical system, landscaping and other
on-site furnishings. The second project consists of building the water and sewer
lines on Lampson Avenue to connect to the City's existing systems.
Agenda Item

The consulting engineer prepared a bid package to advertise and solicit for bids for
Lampson Avenue Well Phase II -Well Equipment and Site Improvements and
Lampson Avenue Well Phase II -Water Transmission Main and Gravity Sewer.
To meet financial constraints, some elements of the project need to be~deferred.
Subsequent phases of the project will include additional pipe lines to inter-
connect this well to our Bolsa Chica facility ($440,000) and installation of a
750kW natural gas emergency generator ($550,000).
The plans and specifications have been completed and approved by the City
Engineer and staff is ready to solicit for bids. Plans and specifications are
available for review in the City Engineer's office.
FINANCIAL IMPACT:
Staff has understood the estimated cost to complete the Lampson Well project
was $2,000,000. Therefore, the Water CIP program was developed under this
assumption. The engineer's estimate for the Lampson Ave Well Phase II is
$3,310,025. Other expected costs are estimated at $200,000 and would include
inspection and contingencies. The engineers estimate to complete the project in
its entirety is $4.6 million. Thus, we recommend deferring some improvements to
subsequent phases and reviewing the water CIP once definitive costs are known.
In the 09/10 Budget, the water capital projects and funding are broken down as
follows:
Project Carry over 09/10
Water System Infrastructure Repairs $1,150,000 $400,000
Lampson Ave Well Phase 2 $2,000,000
Beverly Manor Station Rehab. $1,500,000 $1,200,000
New 18" Water line in OC Flood Control 500 000
$2,650,000 $4,100,000
TOTAL WATER FUNDS AVAILABLE $6,750,000
In reviewing the scope of work for the Water System Infrastructure Repairs, this
project can be reduced down to $700,000. The New 18" Water line in OC Flood
Control can be postponed to the following year.
The revised FY 09/10 CIP budget for water projects would be as follows:
Lampson Ave Well Phase 2 (incl. inspection/contingencies) $3,510,000
Beverly Manor Station Rehab $2,540,000
Water System Infrastructure Repairs 700 000
TOTAL $6,750,000
Formal budget amendments will be recommended at time of award.
