228th St SE widening clears environmental review, comment window open

What the records say

The City of Bothell has issued a Determination of Non-Significance (DNS) for the proposed widening of 228th Street SE, generally from 35th Avenue SE to 39th Avenue SE, spanning both Bothell and Snohomish County. A DNS means the city reviewed the project's environmental checklist and determined it will not have a probable significant adverse environmental impact, so a full Environmental Impact Statement is not required. ¹

• The city determined the 228th St SE widening project will not have a probable significant adverse environmental impact, so no EIS is required. ¹
• The project widens the road from three to four lanes and adds sidewalks, bike lanes, stormwater improvements, signal modifications, and street lighting. ¹
• The project spans Bothell and Snohomish County and avoids direct impacts to three wetlands and Coal Creek. ¹
• Comments and appeals on the DNS must be received by 5:00 PM on July 16, 2026. ¹

Why it matters

This decision clears a major environmental hurdle for the road widening project. Residents who use 228th St SE can expect wider lanes plus new sidewalks, bike lanes, and lighting if the project moves forward. The notice also opens a public comment and appeal period that ends July 16, 2026, at 5:00 PM, giving residents a chance to weigh in on the environmental findings. ¹
