December 19, 2024 Regular Board Meeting Agenda Packet - Page 90 of 97 Page 4 of 10 Engineering & Operations Committee Minutes December 4, 2024 Page 3 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. December 19, 2024 Regular Board Meeting Agenda Packet - Page 91 of 97 Page 5 of 10 Engineering & Operations Committee Minutes December 4, 2024 Page 4 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.

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.
