Approve Increase to the Duration Contingency for Contract No. WD-2901, San Andreas Pipeline 3 – Drainage & Erosion Repair at Junipero Serra Park
Summary of Proposed
Commission Action:
Approve an increase of 180 calendar days (approximately six months) to the existing duration contingency for Contract No. WD - 2901, San Andreas Pipeline 3 – Drainage & Erosion Repair at Junipero Serra Park, with JDB & Sons Construction , Inc., for a revised duration limit of up to 576 consecutive calendar days (approximately one year and seven months), due to unforeseen poor soil conditions that required field modifications to a storm drain pipe, leading to a delay in completion of the contract work, with no change to the contract amount.
Background: The San Franc isco Public Utilities Commission (SFPUC) Water Enterprise requires repair work to address a leaking storm drain pipe that eroded a hillside and created a deep gully adjacent to SFPUC San Andreas Pipeline No. 3 easement. The storm drain
pipe is
located on property owned by San Mateo County, and discharges stormwater from catch basins that are owned by the City of San Bruno. Through a Memorandum of Understanding, the City of San Bruno has agreed to share the cost of the work and to own and maintain the new st orm drain pipe, and San Mateo County has agreed to maintain the repaired gully.
On March 25, 2025, by Resolution No. 25-0053, this Commission awarded Contract No. WD-2901, San Andreas Pipeline 3 – Drainage & Erosion Repair at Junipero Serra Park , to JDB & Sons Construction, Inc. The original contract amount was $1,192,500 and the original contract duration was 360 consecutive calendar days.
Scope of Contract: The contract work is within Junipero Serra Park, in San Mateo County, where the SFPUC has an easement for the SAPL3. The purpose of this project is to stabilize the hillside and protect the SAPL3 easement area.
The contract work consists of:
• Mobilization and demobilization;
• Traffic control work;
• Shoring of work area above gully;
• Installation of rock slope protection within the existing gully; Agenda Title: WD-2901, San Andreas Pipeline3 – Drainage & Erosion Repairs at Junipero Serra Park Commission Meeting Date: September 8, 2026
• Construction of approximately 180 linear feet of 12 -inch diameter high-density polyethylene (HDPE) storm drain pipe, including HDPE cleanouts, concrete thrust blocks, concrete trench dams, and a 12 -inch diameter perforated HDPE
spreader tee;
• T ree protection; and
• Restoration of landscape and park improvements impacted by construction.
Modifications to the
Contract:
Proposed Increase to Duration Contingency: Staff recommends the Commission approve an increase of 180 calendar days to the existing duration contingency, for a revised duration limit of up to 576 consecutive calendar days, due to unforeseen poor soil conditions that require field modifications, leading to a delay in completion of the contract work, with no change to the contract amount.

Environmental
Review:
On October 17, 2013 , the Planning Commission certified the Final Environmental Impact Report (Final EIR) for the Peninsula Pipelines Seismic Upgrade Project (Case No. 2011.0123E), prepared pursuant to the California Environmental Quality Act (CEQA).
On October 22, 2013, by Resolution No. 13-0161, this Commission adopted CEQA Findings, including a Statement of Overriding Considerations, and a Agenda Title: WD-2901, San Andreas Pipeline3 – Drainage & Erosion Repairs at Junipero Serra Park Commission Meeting Date: September 8, 2026
Mitigation Monitoring and Reporting Program, pursuant to the CEQA, and approved the Peninsula Pipelines Seismic Upgrade Project.
On April 12, 2017, the Planning Department issued an Addendum to the Final EIR (Case No. 2011.0123E), which evaluated the replacement and/or sliplining of four segments of San Andreas Pipeline No. 2.
On January 22, 2019, by Resolution No. 19- 0014, this Commission reviewed and considered the Addendum to the Final EIR and approved Contract No. WD-2829R, San Andreas Pipeline No. 2 Replacement Project.
During construction, a leaking storm drain pipe was found at one segment, which was eroding the hillside and causing a deep gully adjacent to SFPUC’s pipelines easement.
On September 5, 2023, the Planning Department issued a Minor Project Modification to the Final EIR to extend the storm drain culvert and stabilize the eroded gully to protect San Andreas Pipeline No. 3, which is located in SFPUC’s easement closest to the gully, determining that no supplemental environmental review was needed beyond the Minor Project Modification.
This action is within the scope of the Project authorized under the Final EIR, as modified by the Addendum and the Minor Project Modification.
