Posted on 05/01/2019

  • Exploration Park Construction. Work is currently underway at Exploration Park to transform it into a beautiful and functional neighborhood park. Construction is expected to wrap up in early fall. The park is closed to the public during construction and is fenced off. The work takes place during daytime hours, and has limited noise due to excavators and construction vehicles.
  • Street Pavement Markings. Work will begin in in the next several weeks to refresh pavement markings on City arterials and collector routes (those roadways that help move traffic from local streets to arterials), as well as in some neighborhoods. This includes yellow center lines, white fog lines, crosswalk bars, bike symbols and other pavement markings. In addition, some raised pavement markers will be installed, including replacing some that were removed during snow removal efforts. The City also is coordinating with the Washington State Dept. of Transportation to conduct similar work on SR 96 (132nd Street SE) and SR 527 (Bothell-Everett Hwy), though their timeline is unclear. Traffic control and flaggers will be provided during work as needed and will ensure traffic flow. Please avoid driving over fresh paint, as it could splatter onto vehicles. The project will take about six weeks to complete.
  • Concrete Shaving on Sidewalks. The perennial work to smooth out tripping hazards along City sidewalks will begin in late spring. The cement’s ridges are ground down where sidewalks have lifted up over roots or settled with the ground. More than 60 sites will be addressed around the City. The work is expected to take three days. In the meantime, sidewalk hazards have been spray painted for easy identification to help people avoid tripping.
  • Surface Water Infrastructure Repairs. The largest project the City is undertaking this summer is repair or replacement of larger surface water pipes that are considered “F failures” – meaning the pipe is ruptured and its potential failure could have a negative effect on life and/or property, pose a risk of environmental damage, or would obstruct access to critical infrastructure. Twenty F grade faults around the City will be repaired starting in late June or early July. Of the pipes to be repaired, a handful will be handled by other utility providers that inadvertently impacted the stormwater pipes. The repairs are generally surgical and localized in nature, meaning that only a section of pipe will need to be addressed at each site. Surface water infrastructure repairs will be ongoing over the next several years.
“The surface water program will be the most visible in Mill Creek this summer,” said Public Works and Community Development Director Gina Hortillosa. “We will be working closely with neighborhoods in which this work will occur to alert them to our timelines and specific impacts.”

As other Mill Creek construction projects have new information, updates will be made to

Surrounding Mill Creek, other agencies have summer construction projects.
  • Washington State Dept. of Transportation has several projects that will impact the Mill Creek community. One final closure of the westbound trestle on U.S. 2 will divert southbound drivers down Hwy 9 and through Mill Creek; the date is dependent on weather and information will be forthcoming. WSDOT also will conduct a grind and inlay on I-5 between SR 104 and 196th Street SE, which will have ramp impacts at 164th; this work will take place between 9 p.m. and 5 a.m. throughout the summer. Finally, WSDOT will complete the grind and inlay between I-5 and Seattle Hill Road, including adding permanent lane markings; the work is underway now through August.
  • Snohomish County continues phase one of its 35th Avenue SE project between Seattle Hill Road and 180th. This work is tentatively scheduled through July and will have lane closures. Also, in conjunction with Community Transit, the County will be pouring sidewalks to the new Green Line stations on 132nd Street SE and 128th Street SE at Elgin Way; this work will have single lane closures during the day and the work is expected to last through June.
  • Community Transit is continuing through May with grind and overlay work on the Bothell Everett Hwy (SR 527) at 164th Street SE. This is a night-time project.
  • Puget Sound Energy is replacing a gas main at 164th and SR 527. This also will be night-time work over five weeks and will be conducted in coordination with Community Transit’s project.
  • Snohomish County PUD has an underground power project on 134th Place SE and Puget Park Drive SE that will occur June through August. This will result in single-lane closures during non-rush hours.

“As the City receives updates on any of these projects from other jurisdictions, we will share them with our community in real time on social media,” said Communications and Marketing Director Joni Kirk. “Summer is the prime construction season, and we want to do our best to help our community to be informed.”

The City will predominantly use Facebook,, to communicate construction impacts.
