review of the bids and determined that XXXXX is the lowest responsive and responsible
bidder. References were provided for XXXXX and staff received satisfactory feedback. A
summary of bids received is shown in Attachment 2. Central San will administer the
construction contract and provide contract administration, inspection, survey, office
engineering, 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 CEQA under District 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 Central San's
experience with numerous sewer construction projects of this nature, the relatively short
distances 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.
ALTER NATIVESJCONSiDERATIONS: Reject all bids, which is not recommended.
FINANCIAL IMPACTS: The total estimated project cost is $4,000,000, including design,
bid price, contingency, construction management, and consultant costs as detailed in
Attachment 3. This project is included in the Fiscal Year 2016-17 Capital Improvement
Budget on page 111 with a total estimated project budget of $4,000,000.
COMMUNITY OUTREACH: Central San held a public meeting on April 5, 2017, at the
Collection System Operations Department building in Walnut Creek to assist with any
questions or concerns by the residents along the proposed construction alignments. in
addition, staff has notified and met with several easement homeowners directly to discuss
the upcoming sewer work, construction impacts, project schedule, and receive input.
COMMITTEE RECOMMENDATION: The Engineering and Operations Committee
reviewed this project at its meeting on May 9, 2017, and recommended approval
of the Project contingent on receiving bids at or below the project estimate.
