fencing to enhance site security, and the addition of emergency generators. These improvements are necessary to maintain these crucial infrastructure components and ensure proper protection of neighboring slopes from erosion and damage (Attachment #1).
The proposed improvements at the pump stations will address the following scope of work:
•Lone Oak Pump Station (CI 5673)
oFire hardening at this site will include rebuilding the existing roofing structures to enhance protection against wildfires.
oNew emergency power backup generator will be installed at this location and will be housed in a noise-suppressing enclosure. oDrainage improvements will be constructed at this location to address onsite drainage deficiencies to prevent erosion and water damage, as well as reduce ongoing maintenance upkeep.
oSite security enhancements will be provided with the replacement of the existing access gates and fencing, as well as site lighting. •Erbes Road Pump Station (CI 5738)
oFire Hardening will require rebuilding a portion of the existing pump station to implement a new roofing structure with fire-hardening measures to reduce wildfire risks.
oNew emergency power backup generator will be installed to maintain operations during power outages.
oSite security enhancements will include updated site lighting, and new access gates and fencing.
•Ventu Pump Station (CI 5739)
oFire hardening enhancements will include replacing the existing roof with fire-resistant roofing material.
oElectrical improvements to the site will include replacement of all existing Motor Control Centers (MCCs) as well as provide for overall system enhancements that meet current standards and will improve system reliability.
oSite security enhancements will be provided with the replacement of the existing access gates and fencing, as well as site lighting.
DISCUSSION/ANALYSIS:
The installation of generators at Lone Oak and Erbes Road Pump Stations provides power to critical pump station infrastructures during power outages and ensures water service availability during wildfire events and other emergencies.
The electrical improvement of Ventu Pump Station will improve system reliability and bring the pump station up to the current standards.

The titles and scope of the three capital improvement projects (CI 5673, CI 5738, and CI 5739) as included in the Approved FY 2023-25 Capital Improvement Budget have been revised to more accurately cover the proposed improvements at each site under an individual CI number. This will better serve to capture the full costs of the improvements at each location, helping better capitalize the proposed improvements from a bookkeeping perspective.
