Agenda Date: November 7, 2022
Subject: Supplement #4 - Contract with Tetra Tech, Inc.
Final Design - Port Hadlock Sewer
Statement of Issue: This contract with the County's sewer design team led by Tetra Tech,
Inc. is for final design, specifications, and cost estimates for the wastewater treatment
facility and pressurized sewer collection system for the Core Area (Phase 1) as shown in the
Port Hadlock UGA Sewer Facility Plan Update, 2021. Supplement #4 extends the completion
date for this design contract through June 30, 2023.
Analysis/Strategic Goals/Pro's Et Con's: Design of the wastewater treatment plant is 95%
complete. Design of the sewer collection system is 90% complete. It is anticipated that there
will be a scope/budget Supplement #5 in early 2023 for work remaining to address issues that
have been discovered during the design process. In the meantime, it is necessary to execute
this time extension Supplement #4 so that the contract does not lapse. The first phase of
construction is anticipated to occur in mid-2023.
Fiscal Impact/Cost Benefit Analysis: There is no change to the budget (currently $1,575,120)
with this Supplement #4. The Washington State Legislature has provided $1,422,000 as a
direct appropriation through the Department of Commerce to fund this work. Remaining funds
are coming through an allocation from Jefferson County's share of ARPA rescue funds.
Recommendation: Please sign three (3) originals of Supplement #4 and return two (2) fully
executed originals to Public Works.
