City of Sammamish - COVID-19 (Coronavirus) Information & Resources
This capital project supports the regional effort to improve Kokanee salmon populations in Lake Sammamish. The City will remove barriers to fish migration from the lake to a point beyond East Lake Sammamish Parkway NE. The project will install fish-passable culverts beneath the Parkway, King County’s regional trail, and East Lake Sammamish Shore Lane NE. The project will also replace storm drains with an open stream channel into Lake Sammamish. Additional information can be found on Connect Sammamish.
King County remains a critical partner in this project. Upcoming improvements to the Lake Sammamish Trail require the County to replace the culverts that route George Davis Creek beneath the trail. Additionally, King County will replace the culvert beneath East Lake Sammamish Shore Lane NE.
PROJECT UPDATES (SEP. 2020)
The City continues to work with a consulting team led by PBS Engineering and Environmental for design expertise of this project. PBS recently issued draft plans and specifications (60% complete) and will incorporate comments from the City and other stakeholders before issuing 90% complete documents in mid-November.
PBS also submitted application documents to the Corps of Engineers and Washington State Department of Fish and Wildlife for the required State and Federal permits. Sammamish will conduct shorelines and environmental review after permit applications are submitted to the City in October.
City staff will also conduct additional public outreach to neighbors and the general public this fall. This effort will provide the community with a greater understanding of the project and explain how it may impact residents.
