Subject: Supplement #2 - Contract with Tetra Tech, Inc.
Final Design - Port Hadlock Sewer
Statement of Issue: Supplement #2 extends the completion date for this design contract.
This contract with the County's sewer design team led by Tetra Tech, Inc. is for final design,
specifications, and cost estimates for the sewer treatment facility and pressurized sewer
collection system for the Port Hadlock "Core Area" as shown in the Port Hadlock Wastewater
System Value Engineering Review completed in May 2019.
Analysis/Strategic Goals/Pro's a Con's: The Port Hadlock Wastewater System Value
Engineering Review completed in May 2019 determined that significant initial costs savings
could be realized by using newly available small, pre-packaged membrane bioreactor (MBR)
equipment and a pressurized collection system. This will allow the sewer to start small in the
Port Hadlock "Core Area" and grow as demand dictates. Design work is underway, currently
at approximately 60% complete. Final completion is anticipated in summer 2022 with final
approval by the Department of Ecology in September 2022.
Fiscal Impact/Cost Benefit Analysis: $1,472,665. The Washington State Legislature has
provided $1,422,000 as a direct appropriation through the Department of Commerce to fund
this work.
Recommendation: Please sign three (3) originals of Supplement #2 and return two (2) fully
executed originals to Public Works.
