Residents near Bellingham's Sehome neighborhood should expect months of late-night construction noise starting in October, after the Bellingham City Council voted unanimously to approve a noise exemption that will allow utility crews to work along Samish Way between 10 p.m. and 7 a.m. The Samish Utility Replacements project is expected to run through May 2027 and will replace aging sewer infrastructure along one of the city's busiest commercial corridors.
What the Project Involves
The core of the project is the replacement of an aging sewer line running along Samish Way between Bill McDonald Parkway and East Maple Street. The sewer in question is described as aging, meaning it has reached a condition where it needs to be replaced rather than repaired. Sewer line failures on high-traffic commercial streets can be disruptive and costly, and proactive replacement is generally far less expensive and less damaging to businesses and infrastructure than an emergency repair following a line collapse or overflow.
The project also includes secondary work on G Street between Halleck Street and Brier Lane, and on North Street between Cornwall Avenue and Ellis Street. That portion of the work will take place during daytime hours and may involve some temporary road closures. Crews are expected to finish the G Street segment before shifting their focus to the main Samish Way corridor.
Much of the Samish Way work is scheduled for nighttime hours specifically to reduce the impact on the corridor's businesses and the heavy daily traffic volume the road carries. Samish Way is one of Bellingham's primary commercial arterials, running through a stretch that includes retail, restaurants, gas stations, and other businesses that would be significantly disrupted by daytime lane closures over an extended period. The council's decision to grant the noise exemption reflects that tradeoff: nighttime work is louder for nearby residents, but daytime work would create broader economic disruption.
What Residents Near Sehome Can Expect
The Sehome neighborhood sits adjacent to the Samish Way corridor, and residents in that area will be within earshot of nighttime construction activity for an extended stretch. The project is expected to involve approximately 130 days of nighttime work on Samish Way, giving an indication of just how extended the disruption period will be. Construction equipment including excavators, trucks, and compactors typically generates significant noise, and even with best-practice noise mitigation measures, residents within a few blocks of the work zone are likely to notice the activity.
The City of Bellingham's noise ordinance normally restricts construction activity during nighttime hours in residential areas. The unanimous council vote on Monday, September 14, granted a specific exemption for this project, recognizing that the public benefit of completing the sewer replacement efficiently outweighs the temporary disruption to nearby residents. Exemptions of this kind are not uncommon for large utility projects in urban areas where daytime work would be more disruptive overall.
Residents who have questions or concerns about the project can contact the City of Bellingham Public Works department, which is managing the project. The city typically posts construction updates and community notifications on its official website as projects get underway.
Timeline and What Comes Next
Construction is scheduled to begin in October 2026 and is anticipated to conclude in May 2027, representing approximately seven months of active work. The total project is expected to take 150 days to complete, including the 130 nighttime work days on Samish Way and the daytime work on G Street and North Street.
Drivers using Samish Way should be prepared for potential lane restrictions or temporary road closures during construction, though the nighttime scheduling is intended to minimize the impact on daytime traffic. G Street and North Street segments will see some temporary closures during the daytime phase of the work, and drivers in those areas should watch for signage and plan alternate routes as needed.
Western Washington University, whose main campus sits just south of the Sehome neighborhood near Samish Way, may also experience some indirect effects from the construction, particularly during evening and overnight hours when the nighttime crews are active. Students living in off-campus housing in the Sehome area should be aware that the noise exemption means construction can legally continue through the night.
For ongoing updates on the project schedule, detour information, and any changes to the work timeline, residents can monitor the City of Bellingham website or sign up for city notifications. The Whatcom County road closure and restrictions page also provides a broader view of active construction projects affecting travel across the county this fall.
