City Hall to function as warming center

City Hall and other public facilities are closed for typical business Nov. 22, as crews clear away debris from this week's storm.  We encourage everyone to stay at home, shelter in place, until the roads are safe. If you need a place to warm up, City Hall will function as a warming center until 5 p.m.

Zackuse Creek Fish Passage and Stream Restoration

Project Overview

Spawning areas for native kokanee salmon have reduced to a handful of tributaries to Lake Sammamish when once they were known to spawn throughout Lake Washington, the Sammamish River, and Lake Sammamish. The decline of the local population has been of special concern to Sammamish residents, fisheries and native tribes. Without diversity in available spawning habitat, a single localized event, whether natural or anthropogenic, could destroy the entire population.

The Zackuse Creek Fish Passage and Stream Restoration project will aid in the reestablishment of Zackuse Creek as a kokanee spawning area. The project includes two primary objectives: 

  1. Replace the existing culvert under East Lake Sammamish Parkway (ELSP) so that it is fully fish passable and with design elements that emulate a natural stream bed.
  2. Restoration of approximately 400 linear feet of Zackuse Creek upstream of the culvert.

Public Outreach

Two public open houses were conducted for the Zackuse Creek Fish Passage and Stream Restoration Project. Details are available below.

Public Outreach

Two public open houses were hosted 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 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.
