Zackuse Creek Fish Passage Culvert and Stream Restoration Project


Project Description

The City will construct a new fish passable culvert under East Lake Sammamish Parkway located south of Louis Thompson Hill Road.  The project also includes restoring Zackuse Creek upstream of the culvert. 

Project Updates

Sammamish and King County are anticipating an agreement that will combine the City culvert and stream restoration project with the King County culvert replacement projects for Zackuse Creek.  This will provide effective, integrated planning, design, permitting, and construction of both projects.  Permits are anticipated to be submitted by mid-May.   Construction is expected to begin July 2018 with project completion in Fall 2018.
