SUMMARY:
On May 28, 2019, the Board set the time and date for a public hearing on the Engineer’s Reports for the subject Projects. Staff is recommending that the Board hold this public hearing and consider adoption of the Resolution (Attachment 1) to approve the Engineer’s Reports and to approve the Projects. The Project summaries are presented below.
Vasona Pump Station Fence and Gate Replacement
The objective of the Vasona Pump Station Fence and Gates Replacement Project is to enhance the physical security of the facility. The Project scope includes replacement of 1,600 linear feet (LF) of existing 6-foot high fencing with 8-foot high mini-mesh chain-link fence; installing 500 LF of new fencing along other segments of the District’s property line; replacing one existing and installing two new 6-foot wide pedestrian gates; replacing three existing and installing one new 25-foot long and one 10-foot long manual vehicular gate; and installing one new automatic vehicular security gate. The total Project cost is estimated to be $620,000.
Santa Teresa Water Treatment Plant (STWTP) Air Wash Pipeline Replacement
The objective of the STWTP Air Wash Pipeline Replacement Project is to extend the useful life and increase the plant’s reliability. The Project scope includes removal and replacement of 1,550 LF of above-ground, 12-inch mortar-lined steel pipe, and relining of 671 LF of underground, 12-inch mortar-coated steel pipe at the east and west filter basins and galleries. Staging of this work will be coordinated between the east and west sides of plant. The estimated total cost of this Project is $960,000.
Pacheco Pumping Plant Priority 1 Fire Alarm and Suppression System Improvements
The objective of the Project is to reduce the risk of a pumping plant shutdown due to fire damages. The Project will install a clean-agent fire suppression system to work in conjunction with the existing water-based system. Major Project features include the installation of a Very Early Smoke Detection Apparatus (VESDA) smoke detection system; replacement of the existing underfloor smoke detectors; installation or replacement of manual pull stations and heat detectors; installation of a new fire department standpipe connection; and retrofitting the fire hose nozzles. The estimated total cost of this Project is $1.9 million.
Engineer’s Report
Section 12 of the District Act requires the Board to conduct a public hearing to hear testimony on a project when: 1) the project is new construction and 2) the project is funded by a single or joint zone of benefit. As the above-described Projects meet both conditions, staff has prepared an Engineer’s Report for each Project (Attachments 2, 3, and 4) for the purpose of public disclosure. The Notice of Public Hearing for these Engineer’s Reports (Attachment 5) was published in accordance with the District Act, and has been made available at the District Headquarters Building (5700 Almaden Expressway, San Jose, California) and on the District’s website at: http://valleywater.org/PublicReviewDocuments.aspx
Next Steps:
If the Board approves the Projects, the upcoming milestones are:
A. Board Adoption of plans and specifications and authorization for construction bidding for all 3 Projects: July 2019
B. Board award of construction contracts for all 3 Projects: September 2019
C. Construction initiation for all 3 Projects: October 2019
D. Construction completion: Vasona Pump Station Fence and Gates Replacement-March 2020; STWTP Air Wash Pipeline Replacement-April 2020; Pacheco Pumping Plant Fire System Improvements-May 2020.
Attachment 6 (Project Delivery Process Schematic) highlights the current Project phase and the staff recommendations currently before the Board.
FINANCIAL IMPACT:
The estimated cost to plan, design, and construct each of the above-described small capital projects will be funded by the Water Enterprise Fund as detailed below:
1. $620,000 for the Vasona Pump Station Fence and Gates Replacement Project with 100% of the costs allocated to Zone W-2 (North County);
2. $960,000 for the STWTP Air Wash Pipeline Replacement with 100% of the costs allocated to Zone W-2 (North County); and
3. $1.9 million for the Pacheco Pumping Plant Priority 1 Fire Alarm and Suppression System Improvements with 79.2% of the costs allocated to Zone W-2 and 20.8% of the costs allocated to Zone W-5 (South County).
There are adequate funds in the Board-approved FY20 Budget to fund the construction of all three Projects.
