Story

A major project that gets under way this summer to restore fish and wildlife habitat along the Snoqualmie Riverrsz_upper_carlson_levee downstream of Fall City will also maintain flood protection for nearby homes and roads.

The Upper Carlson Floodplain Restoration project will remove a 1,600-foot-long levee to improve the river’s connection to 50 acres of forested floodplain within the County-owned Fall City Natural Area. The aging levee will be replaced with a modern flood-hazard protection structure along Neal Road Southeast.

Because of hazards from construction activities, the project will require closing a two-mile-long reach of the Snoqualmie River to boating and floating for up to four months, beginning June 2. The closure extends from the State Route 202 bridge in Fall City downstream to a point roughly one mile upstream of the boat ramp at Neal Road.

The Fall City Natural Area and adjacent Washington Department of Fish and Wildlife property will also be closed during this period. Vehicle traffic on Neal Road should expect periodic delays, with one lane closed at times within the project area. Truck traffic will also increase at times along Neal Road south of the project site.      

King County acquired the Fall City Natural Area in 2001 with funding from the Salmon Recovery Funding Board for preserving and restoring critical salmon habitat. The site historically contained the mainstem of the Snoqualmie River and now features a forested floodplain with an oxbow channel.

Part of the restoration work includes removing dense infestations of invasive Japanese knotweed and planting the treated areas with native vegetation.

The Upper Carlson Floodplain Restoration Project is funded by grants from:

  • Washington State Salmon Recovery Funding Board and Puget Sound Acquisition and Restoration via Washington Resource Conservation Office and Puget Sound Partnership;  
  • National Oceanic and Atmospheric Administration via The Nature Conservancy;
  • Coordinated Investment for Puget Sound Floodplains Initiative sponsored by The Nature Conservancy and administered by the Washington Department of Ecology;
  • U.S. Environmental Protection Agency via the Snoqualmie Tribe;
  • King County Flood Control District via Cooperative Watershed Management Grant; and
  • King County Department of Natural Resources and Parks.
