Construction resumes October 28, 2026 near SR 104 Lyon Creek fish passage site

Construction will resume Wednesday, October 28, 2026 near the SR 104 Lyon Creek fish passage site for removal of a buried storage tank. Construction will happen from 7am to 3:30pm for about five weekdays. Work will not happen overnight or during weekends.

During working hours, one lane of NE 185th Street will close at the intersection of SR 104. Signed detours will guide people around the closure.

Underground tank removal

During this project, our contractor found a buried fuel storage tank on site that was not previously identified in plans. The tank was discovered midway through construction, after known fuel tanks had already been safely removed.

In recent months, we have worked with the property owner and developed a plan to remove the tank, which is located near the intersection of NE 185th Street and 35th Avenue NE. This storage tank, which is believed to be empty, must be removed.

Our contractor will use industry best practices to remove this final tank and any potentially contaminated soils nearby. Contaminated soils removed from the work zone during tank removal will be disposed of at authorized facilities. Crews will fill around the tank with clean soils and add landscaping before finalizing construction.

Ballinger Way Roundabout Project Update: Temporary Utility Relocations

Temporary Utility Relocations to Support Retaining Wall Construction - September 21, 2026

The City of Lake Forest Park advises residents that retaining wall construction for the SR 104 / NE 40th Place Roundabout Project begins today. To facilitate this work, temporary relocations of overhead electrical and communication lines are scheduled for the week of September 28, 2026.

The City is coordinating these activities with Seattle City Light, Comcast, and Lumen to support construction progress while minimizing potential service disruptions to nearby properties.

Anticipated Service Impacts

Widespread service outages are not anticipated. However, a limited number of individual homes may experience a temporary interruption in electrical or communication service during the relocation work. Residents with planned service interruptions will be notified directly by the appropriate utility provider or project representative.

If an unexpected electrical outage occurs, residents should contact Seattle City Light for outage assistance. For interruptions to internet, telephone, or cable service, residents should contact their respective communications providers.

Water District says no health concerns with discolored water

The Ballinger Way NE Roundabout construction has required the District to temporarily change how water flows through portions of our distribution system. The impacts of these changes, particularly discolored water in some areas, have been greater than we anticipated.

We also recognize that our communication with customers regarding these changes and their potential impacts has not been adequate, and we apologize. As additional shutdowns or system changes are required, we will do a better job of providing advance notice to impacted customers, including information about what to expect and how to prepare.

Changes in water flow can disturb naturally occurring minerals such as calcium and iron within water mains and cause temporary discoloration. There is no health concern associated with the discoloration. Out of an abundance of caution, the District collected water samples from representative locations in the distribution system and all bacteriological samples came back negative.

We have also been in communication with the Washington State Department of Health, Office of Drinking Water regarding the situation and our response.

Discolored water?

If you experience discolored water, run cold water from a bathtub, outside faucet, or other high-flow fixture for 5–10 minutes. If the discoloration persists, contact the District at 206-365-3211 or office@lfpwd.org.

More about roundabouts

View the reel

Multi-lane roundabout? Choose your lane before you enter.

A key difference with multi-lane roundabouts is that you need to pick the right lane before you enter.

As you approach:

• Slow down and look for signs and pavement markings.
• Choose your lane based on where you’re going.
• Yield to all traffic already in the roundabout, including vehicles in the inside lane that might be exiting.
• Enter when there is a safe gap.

Once you’re inside the roundabout, don’t stop or switch lanes. Keep going and use your turn signal when you’re ready to exit.

Remember, signs and pavement markings are there to help you. Follow them instead of making a last-minute lane change.
