sewer overflows, as mandated by the San Francisco Bay Regional Water Quality
Control Board. This project is the eighth phase of sewer renovation in Walnut Creek
(see Attachment 1). The Walnut Creek Sewer Renovation, Phase 8, will renovate
10,000 linear feet of 6 -inch through 12 -inch sewer lines in 35 pipe segments in public
streets and private easements in the city of Walnut Creek. Additionally, four manholes
will be constructed on the Clyde force main for maintenance access. Construction of
the sewers in easements will involve close cooperation with customers for site access
and restoration.

POSITION PAPER
Board Meeting Date: July 7, 2011
subject: AWARD A CONSTRUCTION CONTRACT AND AUTHORIZE THE
GENERAL MANAGER TO EXECUTE CONTRACT DOCUMENTS SUBJECT TO
SUBMITTAL REQUIREMENTS WITH K. J. WOODS, INC. FOR THE
CONSTRUCTION OF THE WALNUT CREEK SEWER RENOVATION, PHASE 8,
DISTRICT PROJECT NO. 5992
District staff prepared the plans and specifications for the project. The Engineer's
estimate for construction of the Walnut Creek Sewer Renovation, Phase 8, is
$1,700,000. This project was advertised on May 20 and May 27, 2011. Seven sealed
bids, ranging from $1,338,000 to $1,993,078, were received and publicly opened on
June 15, 2011. The Engineering Department conducted a technical and commercial
review of the bids and determined that K. J. Woods, Inc. is the lowest responsive bidder
with a bid amount of $1,338,000. A summary of bids received is shown in
Attachment 2.
The District will administer the construction contract and will provide contract
administration, inspection, survey, office engineering, and submittal review. The funds
required to complete this project, as shown in Attachment 3, are $1,681,700. The total
cost of the Walnut Creek Sewer Renovation, Phase 8, is anticipated to be $2,081,700.
This project is included in the fiscal year (FY) 2010 -11 Capital Improvement Budget
(CIB) on page 28. Staff has conducted a cash -flow analysis of the Collection System
Program budget and concluded that adequate funds are available for this project.
Staff has concluded that this project is exempt from the California Quality Act (CEQA)
under CCCSD CEQA Guidelines Section 15302, because it involves replacement of
existing sewer facilities at substantially the same locations and with the same purpose
and level of activity as the facilities being replaced. Any capacity increases are for
non - growth inducing, wet weather purposes. This project also is exempt under District
CEQA Guidelines Section 15061(b)(3), since it can be seen with certainty that there is
no possibility that the activity in question may have a significant effect on the
environment. This certainty is based on the District's past experience with numerous
sewer construction projects of this nature, the relatively short distances involved, and
the District's mitigating construction specifications. These specifications are
standardized general and special conditions that are made part of the project bid
documents to address environmental considerations, such as protecting trees and
riparian areas, as well as compliance with applicable federal, state, county, district,
municipal, and local laws, ordinances, orders, and regulations. Approval of this project
will establish the Board of Directors' independent finding that this project is exempt from
CEQA.
