CC 2019-03-12_08d Lift Station No 1 Force Main Replacement ProjectMEMORANDUM
TO: CITY COUNCIL
FROM: BILL ROBESON, PUBLIC WORKS DIRECTOR
BY: JILL MCPEEK, CAPITAL IMPROVEMENT PROJECT MANAGER
SHANE TAYLOR, UTILITIES MANAGER
SUBJECT: CONSIDERATION TO APPROVE CONSTRUCTION PLANS AND
SPECIFICATIONS AND ENVIRONMENTAL EXEMPTION FOR THE LIFT
STATION NO. 1 FORCE MAIN REPLACEMENT PROJECT, PW 2017-07
DATE: MARCH 12, 2019
SUMMARY OF ACTION:
Authorization to solicit bids for the replacement of the Lift Station No. 1 force main, which
is a major component of the City’s sewer system. Bids are due by April 23, 2019, with
work anticipated from July to November 2019.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The FY 2018/19 and 2019/20 Capital Improvement Program Budget includes an
allocation of $1,164,880 for the design, inspection, construction, and contingencies of the
subject project. Staff time will be necessary to oversee the construction of the project.
RECOMMENDATION:
It is recommended the City Council:
1. Approve the construction plans and specifications for the Lift Station No. 1 Force Main
Replacement Project, PW 2017-07;
2. Authorize the City Clerk to advertise for construction bids;
3. Find that the project is categorically exempt from the California Environmental Quality
Act (CEQA) pursuant to Guidelines Section 15301(b);
4. Direct the City Clerk to file a Notice of Exemption.
BACKGROUND:
Lift Station No. 1 is the largest of the City’s five sewer lift stations and conveys
approximately 17% of the City’s total wastewater flow. The lift station was constructed in
1973 and includes over 3,000 feet of 8-inch cast iron force main that travels within West
Branch Street, crosses under Highway 101 and discharges to a manhole located on El
Camino Real. The pipe has experienced four breaks since 1987 indicating it has reached

the end of its useful life and is in need of replacement. Because of this series of breaks,
the replacement of the force main is identified as a necessary project in the City’s adopted
Wastewater System Master Plan, December 2012. The most recent break was in
December 2015.
On April 24, 2018, the Council approved a purchase order with MKN & Associates, Inc.
for the design to replace the Lift Station No. 1 force main. Since then, City staff has worked
with MKN to complete the design, which includes the elimination of the Highway 101
undercrossing.
In order to bid the project and provide immunity to the City, the City Council approves the
specifications prior to the construction bidding process. Also, the scope of work is required
to be environmentally cleared prior to bidding.
ANALYSIS OF ISSUES:
The project scope of work consists of the installation of approximate 3,500 linear feet of
8-inch sewer force main pipe along West Branch Street between Oak Park Boulevard
and Brisco Road using horizontal directional drilling (HDD) techniques. HDD will help
minimize traffic impacts during construction, in particular around the Five Cities Center
area.
The proposed contract time is 90 working days. Should successful bids be received and
a construction contract awarded, work is expected to be performed from July to November
2019. Project plans and specifications are available for review at the Public Works
Department.
ALTERNATIVES:
The following alternatives are provided for the Council’s consideration:
1. Approve recommendations as proposed;
2. Do not approve recommendations and request further information;
3. Modify recommendations and approve; or
4. Provide direction to staff.
ADVANTAGES:
The force main replacement will help eliminate the probability of more frequent breaks in
the future and greatly reduces the risk for the potential of substantial fines that can be
imposed as a result of these breaks. The project abandons the current crossing under
Highway 101 which will eliminate potential liability should there be a break or a failure if
the force main were to remain under Highway 101. The project is consistent with the City
Council goal to support City infrastructure.

DISADVANTAGES:
There will be traffic inconveniences to the travelling public during construction. Staff will
monitor the traffic control to conform to the requirements of the Municipal Uniform Traffic
Control Devices manual (MUTCD) to mitigate any negative effects. City inspectors will be
at the site during construction to make adjustments for any isolated instances. In addition,
City staff and the construction manager for the project will notify and coordinate with
adjacent businesses and residents along the proposed force main route to ensure they
are notified in advance of upcoming activities.
ENVIRONMENTAL REVIEW:
The project is categorically exempt from the California Environmental Quality Act (CEQA)
pursuant to CEQA Guideline Section 15301(b) covering the repair and maintenance of
existing facilities of publicly-owned utilities used to provide sewerage.
PUBLIC NOTIFICATION AND COMMENTS:
The Agenda was posted at City Hall and on the City’s website in accordance with
Government Code Section 54954.2.
