Horse Creek is flowing fully in its permanent new alignment! 

"The Horse Creek project presented many complex challenges and was completed during an exciting time that catalyzed Downtown's growth. I look forward to seeing this daylighted stream establish and evolve over the years, enhancing the surrounding redevelopment."

We cut the ribbon!
What a great turnout at the Oct. 5 ribbon-cutting celebration in the library plaza!  Adults and kids alike joined in the fun and learned lots about Horse Creek.

Project description

The project replaced the existing Horse Creek pipe with a hybrid open-channel/culvert system along 98th Ave NE. The system was designed to convey flows exceeding the 100 year storm event and meet the fish passage criteria established by the State Department of Fish and Wildlife. The project begins at NE 188th St, north of Pop Keeney Field, and extends along 98th Avenue NE to the Sammamish River. The stream is within an open channel south of the realigned SR 522.

Phase I
Utility improvements included installation of underground utilities within the 98th Ave NE corridor between NE 183rd St and NE 185th St.

Phase II
Improvements included relocation of the creek from its current location to the new hybrid channel.

Phase II construction schedule

  • Start Construction: July 2014
  • Complete Construction (except landscaping): October 2016
