Agenda Request
To: Board of Commissioners
Mark McCauley, Interim County Administrator
From: Monte Reinders, Public Works Director/County Engineer
Agenda Date: February 14, 2022
Subject: Supplement #3 - Contract with Tetra Tech, Inc.
Final Design - Port Hadlock Sewer
Statement of Issue: Supplement #3 adds scope and budget to the Final Design contract with
Tetra Tech, Inc. for the Port Hadlock Sewer project. Completion time remains unchanged.
Analysis/Strategic Goals/Pro's a Con's: The following scope and budget items are added to
the current contract:
• Old Alcohol Plant sewer extension scoping study. $37,477
This work will develop a concept level design to determine how the Old Alcohol Plant
and marina properties could be connected to the Port Hadlock Sewer in the future.
The Old Alcohol Plant is within the Urban Growth Area (UGA), and the Port Hadlock
sewer system would benefit by having the additional flow and customer base provided
by these properties. It is important to know how this area could be served by sewer so
that provisions for its future connection to the Hadlock Phase I sewer area can be
planned for now. Cost estimates for this extension/connection will be developed.
• Operations/Maintenance/Admin estimating and rate studies. $64,978
This work will update the estimates for operations, maintenance, and administration
costs for the Port Hadlock sewer. The O&M costs in the Sewer Facility Plan contained
many assumptions that can be refined as more information is developed though the
design phase. The Consultant will work with the County and the PUD to develop
detailed costs for the operation, maintenance, and administration of the sewer system
at key design milestones. This information will be used for rate setting and rate
structure creation in a sewer ordinance.
Fiscal Impact/Cost Benefit Analysis: $102,455. This additional work will be funded by the
County through the Tri Area Sewer fund. The County has directed American Rescue Plan Act
(ARPA) money into the Tri Area Sewer fund.
Recommendation: Please sign three (3) originals of Supplement #3 and return two (2) fully
executed originals to Public Works.

PUMP STATION SCOPING STUDY
GENERAL
The scope of services in this amendment provides services for updating wastewater utility financial plan
and provide a scoping study for the Old Alcohol Plant Pump Station.
The Old Alcohol Plant scoping study will better develop and define the pump station to an approximate
15% Design level. This pump station will provide wastewater service for the catchment area focused on
the former Alcohol Plant located on Hadlock Bay Road.The purpose of this scoping study is to determine
the preferred location and size/configuration of a pump station serving the Old Alcohol Plant sub-area
and to develop a Class 3 cost estimate so Jefferson County and property owner can acquire funding to
complete design and construction.
Key work items and outcome of the Old Alcohol Plant pump station study will be as follows:
• Provide adequate information to confirm that a pump station and force main serving the Old
Alcohol Plant subarea can be tied directly in to the Core Area pressure sewer
• Review of septic system records to identify location of septic system equipment, drainfield, and
building drains.
• Review of water use records and development of flow criteria to size the pump station.
• Determine preferred location of Pump Station.
• Determine pump station type, size and configuration at the Old Alcohol Plant area.
• Determine how the pump station force main will be tied in to the Core Area pressure sewer
system in the vicinity of Scott Rd and Curtis Street—determine equipment type,size, and
configuration.
• Coordination with WSDOT on the installation of the force main and variance request for open
cut installation.
• Develop an estimated construction cost.
The services for updating the financial plan will provide better clarity on operation and maintenance
costs and anticipated monthly O&M costs per customer and anticipated wastewater service rates.
Key work items and outcomes of the financial plan update services will be as follows:
• Update the operation and maintenance cost estimate for the Pt. Hadlock Treatment Plant&
Collection System.
• Develop a rate study recommended rate structure to help clarify how rates will be charged.
