body
BACKGROUND
The District filed an application for public water system funding assistance through the Department of Water Resources (DWR) Small Community Drought Relief Program (SCDRP) in November 2021 seeking a total of $637,000 to cover costs associated with the District’s Emergency Drought Response. The project implements groundwater and sub-channel creek supply feasibility investigations and strengthens the system’s ability to sustain water supply during critically dry years. Project elements are listed below.
1. The installation of a seasonal floating intake structure to compensate for declining water levels in Putah Creek due to severe drought;
2. Extending the water supply intake to a nearby alluvium gravel bar and replacing a dilapidated Concrete Masonry Unit (CMU) Intake Utility Building with a new building and a Potassium Permanganate chemical treatment process for pre-treatment of raw water;
3. Purchase and acquisition of portable pumping equipment, hoses and a tank placed at the water supply intake pool to carry out temporary water transfers within the Putah Creek basin from upstream pools to the stationary intake; and
4. Conduct hydrogeologic explorations for a potential alluvial or fractured rock deep well supply in proximity to the Berryessa Estates water service area that can satisfy the community’s maximum daily water demand.
DWR SCDRP Funding Agreement No. 240301B was issued to the District in June 2023 and formally executed on August 28, 2023. Terms of the Funding Agreement allow for eligible project reimbursement expenses dating back to April 29, 2022 through December 31, 2024. The agreement was formally extended, and all work must now be completed by December 31, 2025.
Project Elements 1, 2, and 4 are complete, leaving Project Element 3 - procurement of a portable diesel engine powered pump, hoses and appurtenances for temporary spring feed pool water transfers to a polyethylene tank placed in proximity to the water supply intake, and the procurement and installation of a new steel storage container to store the acquired equipment until needed – as the final project element that the District needs to complete to meet the terms of the SCDRP funding. The engineer’s estimate for Project Element 3 is $85,000.
Design plans and specifications for project element No. 3 were approved and the District was authorized to solicit competitive public bids by the Governing Board at the June 24, 2025 meeting.
Bids were opened on August 14, 2025 (see attached table of bid results). Staff recommends awarding the contract to the lowest responsive bidder, Pridmore Brothers Construction, Inc. of Napa, California for their base bid of $78,000. The base bid is lower than the engineer’s estimate, which is $85,000. The total estimated project cost including construction, construction management and contingency remains $85,000. With the award of this contract, all grant funds are expected to be fully expended.
Pridmore Brothers Construction, Inc. is a local vendor. The Public Contract Code requires that the construction contract be awarded to the lowest responsible and responsive bidder, regardless of whether the low bidder is local or not. Staff reached out to the local construction contractor community by advertising the request for bids in the Napa Valley Register and the Solano-Napa Builder’s Exchange, and by posting on the County website. Staff also sent “Notices to Contractors” to the local construction community.
Requested Action:
1. Award of Contract to Pridmore Brothers Construction, Inc. of Napa, California for their low total bid of $78,000 for construction of the Project and authorize the Chair to sign the construction contract.
