ISSUE
On February 1, 2018, bids were received for the construction of the Walnut Creek Sewer
Renovations, Phase 12, District Project 8435 (Project). The Board of Directors (Board) must award the
contract or reject bids within 50 days of the bid opening.
BACKGROUND
The Project is part of the ongoing sewer renovation within the Collection System Program of the Capital
Improvement Budget (CI B)to replace or rehabilitate deteriorated sewer infrastructure that is in poor
condition. This work is coordinated with local jurisdictions, cities, utilities, and private property owners and
tenants.
The scope of work for the Project consists of replacement or rehabilitation of approximately 9,000 feet of
sewer mains, primarily 6-inch clay sewers, construction of manholes, and other related work within public
rights-of-way and easements. The Project is located within the Saranap area of unincorporated Walnut
Creek, as identified in Attachment 1.
Central San staff prepared the plans and specifications for the Project. The Engineer's estimate for
construction is $3,200,000. This Project was advertised on January 19, and 24, 2018. sealed bids

ranging from $x,xxx,xxx to $z,777,777were received and publicly opened on February 1, 2018. The
Engineering and Technical Services Department conducted a technical and commercial review of the bids
and determined that [Company Name] is the lowest responsive and responsible bidder. References were
provided for[Company Name] and staff received satisfactory feedback.A summary of bids received is
shown in Attachment 2. Central San will administer the construction contract and provide construction
management, resident engineering, inspection, survey, administration and submittal review. Consultant
inspection will be used to supplement staff on an as-needed basis.
CEQA:
Staff has concluded that this Project is exempt from California Environmental Quality Act(CEQA) under
Central San CEQA Guidelines Section 15302, because it involves replacement of existing 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. The Project also is
exempt under Central San 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 Central San's experience with numerous sewer construction projects of this nature,
the relatively short distance involved, and Central San'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.
ALTERNATIVES/CONSIDERATIONS
Reject all bids, which is not recommended. Delaying or postponing the sewer replacement work may not
produce cost savings, especially in the current bid climate which has seen a significant rise.Additionally,
several sites have been coordinated with the public and Contra Costa County's upcoming 2018 paving
plan.
FINANCIAL IMPACTS
The total estimated Project cost is $4,310,000, including planning, design, bid price, contingency,
construction management, and consultant costs as detailed in Attachment 3. This Project is included in
Fiscal Year(FY) 2017-2018 Cl B on page 130 with a total estimated project budget of$4,100,000. The
additional budget required, $210,000, will be included in the proposed FY 2018-2019 Cl B.
