Zackuse Creek Fish Passage 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.  Local, state, and federal permit applications were submitted in May and June 2017.   Construction is expected to begin June 2018 with project completion in Fall 2018.

Public Outreach

Two public open houses are planned for the Zackuse Creek Fish Passage and Stream Restoration Project.  The first public open house was held on March 29, 2017 to introduce the project and receive public comment on the preliminary plans.  The second public open house is scheduled for January 10, 2018 to share the 90% design plans with the public and to receive any final public comment before finalizing the plan. On July 18, 2017, the City Council approved the plan for full road closure of East Lake Sammamish Parkway during culvert construction with planned detour routes.  The road closure, detour routes, and traffic control plan will be made available as soon as they are finalized.
