SUBJECT: Kelley (CI 5752), Lang Ranch (CI 5753), Meadows (CI 5754), and Oakbrook (CI 5755) Reservoir and Pump Station Improvements Projects
RECOMMENDATION:
1. Approve budget appropriation and expense in FY 2025-26 in the amount of $19,300 as follows: $14,700 from A/C #613-0000-341-9900 (Water Capital Fund – Net Position) to A/C #613-8030-682-8300 (Water Capital Fund – CI 5752 Improvements at Kelley Reservoir and Pump Station), and $4,600 from A/C #613- 0000-341-9900 (Water Capital Fund – Net Position) to A/C #613-8030-682-8300 (Water Capital Fund – CI 5753 Improvements at Lang Ranch Reservoir and Pump Station).
2. Find that the project is Categorically Exempt from the California Environmental Quality Act (CEQA) pursuant to Title 14, California Code of Regulations, Section 15301, Class 1 – Existing Facilities (repair and maintenance of an existing facility).
LEVINE ACT ITEM: No
FINANCIAL IMPACT:
$19,300 Increase to Adopted FY 2025-26 Water Capital Fund Budget. $19,300 increase to Adopted FY 2025-26 Water Capital Fund Budget is requested to address construction-phase costs as CI 5752 and CI 5753 exceeded the originally approved project-specific contingency amounts. The estimated total cost of the four projects is $1,566,231, which is below the total four-project budget of $2,080,000.

BACKGROUND:
The City’s Public Works Department is responsible for managing the City's water storage and distribution infrastructure, which includes 11 Calleguas Municipal Water District (Calleguas) turnouts (connections to the Calleguas supply), four hydropneumatic pump stations, 16 pump stations, 16 reservoirs, and two booster stations. Many of these facilities have been in operation for over 50 years and require upgrades to meet current operational standards and address community expectations. Essential improvements are needed to enhance wildfire resilience, improve site drainage, prevent accidental tank overflows, safeguard pump and electrical equipment, secure enclosures, and add emergency generators and disinfection boosting stations.
On September 23, 2025, City Council awarded a construction contract to Filanc (Escondido, CA) in the amount of $1,235,100, plus a contingency of $123,510 for construction of the Improvements at Kelley (CI 5752), Lang Ranch (CI 5753), Meadows (CI 5754), and Oakbrook (CI 5755) Reservoir and Pump Station sites (Attachment #1). The improvements at these Reservoir and Pump Stations are designed to enhance operational efficiency, reliability, and resilience of these critical infrastructure sites, particularly against wildfire risks.
DISCUSSION/ANALYSIS:
The Kelley Reservoir and Pump Station Improvements Project (CI 5752) included driveway and pavement improvements, enhancements to the Whitegate Road entrance, installation of a new canopy, and fire hardening roof upgrades to improve site access and protect the facility against wildfire related hazards. The Lang Ranch Reservoir and Pump Station Improvements Project (CI 5753) included fire resilience roof upgrades, installation of protective canopies over electric motors, retaining wall construction, pavement rehabilitation, and excavation to expose tank pad weepholes to help prevent corrosion and extend the service life of the facility. The Meadows Reservoir Improvements Project (CI 5754) included vault access improvements consisting of a new access gate, installation of safety railings along the vault edge, and new canopies to protect critical equipment from weather exposure. The Oakbrook Reservoir Improvements Project (CI 5755) included installation of a new canopy to protect essential equipment from environmental exposure and improve the long-term reliability of the facility.
The construction for these projects was completed in May 2026. The infrastructure upgrades are essential for maintaining the long-term functionality and resilience of the City’s water distribution system, especially in light of increasing wildfire threats and other emergency conditions.
Although these four sites were awarded under one construction contract, City Council approved specific contract and contingency amounts for each project.

Additional costs identified during construction of CI 5752 and CI 5753 are slightly higher than the original contingency for those two projects; therefore, staff is seeking City Council approval for those project-specific increases. An administrative budget adjustment is not appropriate in this circumstance because City Council has already approved contract and contingency amounts for each specific project.
At Kelley Reservoir and Pump Station (CI 5752), during reconstruction of the driveway, a shallow 8-inch pressurized water line that serves numerous residences was discovered, which required a special concrete blanket to protect the line, avoid service disruption, and accommodate driveway grade changes. There was also a Southern California Edison duct bank located under a proposed pile which resulted in a larger spread footing to straddle the existing duct bank. Additional costs were also incurred for emergency tree removal necessitated by high wind hazard conditions at the site.
At Lang Ranch Reservoir and Pump Station (CI 5753), additional work was incorporated to construct secondary containment for a future disinfectant boosting system. Although that construction had originally been included under a separate project, it was more efficient and cost-effective to complete the work while the area was already demolished as part of this contract. An additional 1,800 square feet of paving area was also added to the scope to repair damaged areas that needed to be addressed to improve site drainage, which further increased construction costs.
No additional construction costs were incurred, and contingency was not used at Meadows (CI 5754) or Oakbrook (CI 5755) Reservoir and Pump Stations. Those contingency amounts; however, remain tied to their respective City Council- approved projects and are not available to be administratively transferred to CI 5752 or CI 5753. Once the additional budget and expense authority is approved, staff will issue Change Order No. 1 which is required to address additional construction associated with necessary field modifications due to unforeseen field conditions and added scope at certain project sites as detailed above.
