City Council OKs $13.19 million guaranteed maximum price for Eastside Arterial Phase 1
Summary
The Redmond City Council authorized a guaranteed maximum price (GMP) amendment with Knife River Corporation for Phase 1 (Ninth Street extension) of the Eastside Arterial project in an amount not to exceed $13,193,373.16. Council heard project scope, schedule, budget sources and traffic routing details during the presentation before the vote.
Redmond City Council on a unanimous voice vote approved a guaranteed maximum price amendment with Knife River Corporation for construction of Phase 1 of the Eastside Arterial project — the Ninth Street extension — not to exceed $13,193,373.16.
Principal engineer Jake Sherman presented the project to council, describing the delivery method and schedule. "We are wrapping up the design of this Ninth Street extension," he said, and said the city used a progressive design-build contract with Knife River and their consultant team to allow earlier contractor involvement, constructability review and cost transparency.
Sherman told council the Phase 1 scope includes about 2,300 feet of new minor arterial (Ninth Street) and about 3,000 feet of new major collector (Kalama Way), each with a 10-foot asphalt multi-use path and concrete sidewalks (7-foot on Ninth Street, 5-foot on Kalama Way). Both corridors will include 6-foot bike lanes, storm swales and street trees; Ninth Street will receive both a new water main and sewer, while Kalama Way will receive a new water main.
Sherman said the project corridor runs from Northeast Hemlock Avenue down to OR 126, through the former Juniper Golf Course area to the Veterans Way/Airport Way intersection. He described why the routing was designed to accommodate over-dimensional loads and to improve access to Highway 126 and Highway 97, relieve congestion and support economic development around airport property.
Councilors asked questions about sequencing and traffic during tie-ins. Sherman explained that the two roundabouts in later phases will be built off-line then tied in to minimize closures and that the design work allowed the team to prioritize buildable segments. He also described the independent cost-estimator process used to reconcile Knife River’s pricing and negotiated elements of the GMP.
City staff presented a project budget of roughly $34.1 million in total by funding source, with transportation system development charges (SDCs) as the primary resource and additional contributions from rental car tax, the general fund and water and wastewater funds. Sherman said the current GMP covers work that will occur on airport property and includes early installation of underground utilities to reduce future GMPs.
After presentation and brief questions, a council member moved to authorize the GMP amendment. Council approved the motion by voice vote. The motion carried.
The council packet and staff comments noted the project is being delivered in multiple phases (Phase 1: Ninth Street extension; Phase 2: OR 126 roundabout; Phase 3: Veterans Way/Airport Way roundabout and related intersections; Phase 4: Ninth Street modernization including widening, bike lanes, sidewalks and a multi-use path). Sherman said the overall team estimated earlier schedules of up to 10 years could be shortened under progressive design-build, and current sequencing aims to substantially compress that timeline.
