Trail open, native plants taking root

Last November the landscaping crew began restoring the project site with native plants. The City reminds trail users that the site is a habitat restoration project, not a recreation area. As such, users should remain on the trail and not disturb the area.

Project description

This project reconnected and restored 1,100 feet of an old remnant channel and floodplain of the Sammamish River.


Project goals included restoring floodplain and channel connectivity and function through:
  • Restoring about 8 acres of floodplain plant community diversity and structure with native plantings and removal of invasive plant species;
  • Hydraulically reconnecting the restored area at both ends to the Sammamish River to make the project accessible as off-channel rearing habitat for salmonids, with an emphasis on Chinook and Coho salmon.
