Public Works staff updated the board on a package of contract amendments and new project obligations intended to finish ongoing work and obligate design money for upcoming projects.

County engineer (Speaker 8) described a time extension for Gibson Olsen’s Woodbrooke Wastewater Treatment Plant evaluation (no cost increase) after a mid‑project scope change driven by Department of Ecology direction. She asked for an additional $50,000 on the local agency professional services agreement with Ecological Land Services to extend the contract through 2026 for environmental permitting and small task work.

On landfill work, county staff said Engineering Solutions LLC requires a $100,000 supplemental agreement to provide construction‑phase QA/QC and on‑site verification for the recently executed vertical gas wells project. "That $100,000 is going to be used to the continuation of, as you recall, about a month ago, we awarded and executed the contract for the vertical gas wells," the county engineer said.

Public Works also proposed supplemental increases to several as‑needed engineering contracts. One motion would extend the Jacobs/Delve Underground geotechnical contract to 2027 and increase the contract maximum from $300,000 to $600,000 to cover planned landslide studies and emergency responses — staff reported $299,175 already spent on that contract.

On roads, staff presented a new Coal Creek Road improvements project (Milepost 1.44–2.0) and requested obligation of preliminary engineering and right‑of‑way funds of $499,500; the project is estimated at about $3.6 million and would be federally funded at 86.5%, leaving approximately 13.5% local match. "The goal is to correct some of the vertical curves out there and give us some basic shoulders and reconstruct the roadway," the county engineer said.

Why it matters: these contract amendments and project obligations fund construction oversight, environmental permitting and critical road and wastewater work that affect county infrastructure and grant reimbursements.

What’s next: the listed amendments and obligations will return to the board as consent or motion items for formal approval on the commissioners’ agenda.
