City seeks $201,000 consultant supplement to finish Knoll Road design; construction estimated at $11–12M

City engineering asked the council to approve a contract supplement for Parametrix to complete final design, right‑of‑way work and construction support for the Knoll Road Corridor north segment, which includes a shared‑use path connection and school access improvements. Staff explained design delays were driven by additional right‑of‑way needs and required coordination with WSDOT and the Transportation Improvement Board.

Josh Raines said the construction estimate for this phase is $11–12 million and the requested supplement is just under $201,000; the supplement would be paid from traffic‑impact fees so no current budget amendment is needed. Staff said they expect to advertise the project for construction in October and begin work in January 2025, with roughly a 12‑month construction period. Council asked about internal staffing and how recent engineering hires would help deliver the capital program; staff said new project engineering hires relieve some workload but additional construction‑management resources will be contracted as needed.

Why it matters: Knoll Road is a multi‑million dollar capital project with sidewalks, roundabout work and a new school entrance that will affect mobility and safety on a key north‑south corridor. The council was briefed on schedule and financing; staff will return on the consent agenda for contract action.
