3. Items for Committee Recommendation to Board
a. Review draft Position Paper to consider the relocation of Contra Costa
Water District's alum residual pipeline, located on Central San's Treatment
Plant, exempt from the California Environmental Quality Act (CEQA)
This item was heard immediately following Item 4.a.
Mr. Frost provided an overview of the draft Position Paper included in the
agenda materials. After a brief discussion, the Committee had no further
questions.
There were no public comments.
COMMITTEE ACTION: Recommended Board approval.
b. Review draft Position Paper to award a construction contract in the
amount of $4,220,550 to Cratus, Inc., the lowest responsive and
responsible bidder for the Lafayette Sewer Renovations, Phase 15,
District Project 100025; transfer $5,754,000 to fund the project; and find
that the project is exempt from the California Environmental Quality Act
(CEQA)
Mr. Randeni provided an overview of the presentation included in the
agenda materials. He explained to the Committee that this project is part
of the ongoing sewer renovation work included in the Capital Improvement
Budget and Collection System Program. The project consists of
renovating approximately 9,400 feet of small diameter pipe to be
completed using open trench, pipe bursting and cured -in-place concrete
methods. Mr. Randeni discussed the extensive public outreach being
done within specific neighborhoods as well as with other utilities and City
staff.
A discussion ensued regarding project complexities such as narrow
residential streets, the need for traffic control, congested utility corridors
and the City of Lafayette's paving requirements. Chair McGill mentioned
the need for further outreach to the Lafayette City Council.
In response to Member Wedington's question regarding Cratus, Inc., Mr.
Lopez confirmed that the District has worked with Cratus, Inc. in the past.
District staff found them to be well-qualified, and very satisfied with their
work.
There were no public comments.
COMMITTEE ACTION: Recommended Board approval.

C. Review draft Position Paper to award a construction contract in the
amount of $4,412,700 to Precision Engineering, Inc., the lowest
responsive and responsible bidder for the Pleasant Hill Sewer
Renovations, Phase 3, District Project 100068 (Project); transfer
$6,235,000 to fund the project; and find that the project is exempt from the
California Environmental Quality Act (CEQA)
Mr. Fitch provided an overview of the presentation included in the agenda
materials. He stated that this Project is part of the ongoing sewer
renovations included in the Capital Improvement Budget and Collection
System Program. The District will be renovating approximately 9,400 feet
in the Gregory Gardens subdivision. The majority of the work will be done
by open trench and some pipe bursting. A discussion ensued regarding
the project complexities as well as outreach efforts.
In response to Mr. Bailey's question regarding what major streets were
involved in this project, Mr. Fitch stated that a small area of the project will
be on Gregory Lane. Due to previous problems encountered with the City
of Pleasant Hill, Mr. Bailey emphasized the importance of coordinating
with Board Member and City of Pleasant Hill liaison Tad Pilecki and the
City of Pleasant Hill.
Member Wedington asked for clarification about how the project will be
funded. Mr. Lopez explained how collection system sewer renovation
projects are funded from the Phase 2 program budget in the Capital
budget. This is why the ability to conduct funding transfers are necessary
and allows the District flexibility in managing scope with other agencies,
Collection System Division, and others.
Mr. Lopez stated that bid amounts for both projects were under the
engineer's estimate, and the apparent low bidder was Precision
Engineering, Inc. A discussion ensued regarding the contributing factors
regarding the bids to include market conditions, escalation, as well as
similar projects of size and scope. The bids received are lower than last
year's pricing and very competitive.
In response to Chair McGill's question regarding the 20 percent
contingency, Mr. Lopez confirmed that staff is asking for 20 percent
contingency because there may be additional sewer work designated for
the final phase (4) to be coordinated with the City during this project.
There were no public comments.
COMMITTEE ACTION: Recommended Board approval.

4. Other Items
a. Receive update on GraysoniWalnut Creek Levee Improvements (DP
7341)
This item was heard as the first order of business.
Ms. Gemmell provided an overview of the presentation included in the
agenda materials. The Levee Improvements Project includes raising
approximately 7,400 linear feet of levee along the treatment plant from
Highway 4 to the Burlington Northern Santa Fe (BNSF) railroad by
approximately three feet and includes new high security fencing south of
Imhoff Drive, as well as the relocation of lighting, cathodic protection, and
securing electrical and instrumentation vaults. The notable benefits
include increased flood protection from catastrophic failures, loss of
service and emergency discharge and/or backup of untreated wastewater
in nearby neighborhoods. She stated that the levee improvements will
ultimately protect several hundred million dollars in existing treatment
plant assets.
Ms. Gemmell also discussed the relocation of Contra Costa Water
District's Alum Residual Pipeline located on Central San's treatment plant.
She explained that relocation is required because the existing pressurized
pipeline would have been located within the new levee footprint, which
would not meet United States Army Corps of Engineers guidelines for
levee design and construction. She also mentioned that the District was
selected for a Building Resilient Infrastructure and Communities (BRIC)
grant.
In response to Ms. Gemmell's question regarding permits, Mr. Frost stated
that all permits have been secured except for the Army Corps of
Engineers 408 permit which is now in a 90 -day waiting period for final
approval.
Per Contra Costa Water District's (CCWD) request, the District will
determine the findings for the California Environmental Quality Act
(CEQA) and CCWD will be listed as a responsible agency.
There were no public comments.
COMMITTEE ACTION: Received the update.
Following this item, the agenda reverted to the original order with Item 3.a.
as the next order of business.

b. Receive Third Quarter update on Central San's Energy Usage
Mr. Shima provided an overview of the District's energy usage included in
the agenda materials. The overall energy cost was lower than normal due
to a credit received for natural gas.
Chair McGill asked if this report included the solar array. Mr. Shima
responded that the solar array has not been connected yet, due to Pacific
Gas & Electric (PG&E) delays.
In response to Member Wedington's question regarding the 2024 energy
usage being much lower than last year, Mr. Shima stated that this report
only includes usage through September 2024 and does not include data
for October, November and December. The annual report will include all
data for the calendar year.
There were no public comments.
COMMITTEE ACTION: Received the report.
