Suiattle River Road Project
Finding of No Significant Impact
The Western Federal Lands Highway Division of the Federal Highway Administration (FHWA) has developed a Finding of No Significant Impact (FONSI) to document the FHWA decision on the Suiattle River Road project in the Mount Baker-Snoqualmie National Forest.
Hard copies of the FONSI were made available for public review in local libraries November-December, 2012. View or Download FONSI Document.
Public Notice of Amended EA Availability
The Western Federal Lands Highway Division of the Federal Highway Administration, in partnership with the Mount Baker-Snoqualmie National Forest propose to repair flood washout sites on the Suiattle River Road, and have developed an Amended Environmental Assessment as a response to the comments raised during the March 2012 release of the Suiattle River Road Environmental Assessment. The Amended Environmental Assessment can be viewed or obtained online here.
Public Notice of EA Availability
An Environmental Assessment analyzing the impacts of the proposed repairs to Suiattle River Road was made available for public review and comment from March 18 to April 20, 2012. Though the comment period has now closed, the EA is still accessible here.
FHWA and the Forest Service are currently reviewing public comments received from the March release of the Environmental Assessment and expect to share information learned within the next two months. Please check this web page for additional information and updates.
The Federal Highway Administration (FHWA), in partnership with the U.S. Forest Service, proposes to repair flood-damaged sites of Forest Highway 26, also known as Suiattle River Road.
The proposal would repair flood damage, re-establish vehicle access, and abandon and rehabilitate sections of Suiattle Road 26:
- Milepost 6.0: Reroute the road for about 2500 feet, with realignment of about 375 to 400 feet inland from the eroded Suiattle River bank. The old roadway would be abandoned and rehabilitated with mitigations for associated wetlands and flood plain reconnection.
- Milepost 12.6: Reconstruct the road 1200 to 1300 feet, with an offset of up to 70 feet from the existing road.
Milepost 13 and 13.5: Reroute around the two washouts with a realignment of approximately 1.1 mile of road upslope of Road 26 and away from the Suiattle River.
The reroute will use Forest Service Road 2670 (0.5 mile) and new road construction through second growth and mature forest to reconnect to Road 26. This reroute starts at MP 12.7 (Road 2670) and reconnects with Road 26 at MP 13.7. Approximately 1 mile of Road 26 would be abandoned and rehabilitated, with associated wetlands and flood plains reconnected.
- Milepost 14.4: Align the roadway for a length of about 900 feet, 55 to 90 feet away from the eroded river bank. The Huckleberry trailhead and parking would be re-established, and the temporary reroute road abandoned and rehabilitated.
- Milepost 20.8: Reconstruct the road for about 350 feet by moving the roadway into the hillside. All work will be outside of the ordinary high water mark for the Suiattle River.
- Milepost 20.9: Construct a series of bridge extension to cross the Downey Creek floodplain to the existing bridge. Remove fill and culvert in bridge approach to accommodate flood flows and channel processes across the floodplain.
- Milepost 22.9: Repair the bridge approach with a concrete faced retaining wall built at the edge of the Sulphur Creek Bridge deck and keyed to the bank.
Proposed Time Frames
- The proposed repair and rehabilitation are anticipated to take two or three summers to complete.
- The proposed years for activities are 2013 through 2014/2015.
EA, Amended EA or FONSI hard copies can be requested from the contacts above or downloaded from the FHWA and Forest Service websites.
Comments that were received in response to this notice, including names and addresses when provided, became part of the Project Record and are available for public review.
- A public meeting was held on March 29th, 2012 from 6:00 PM to 8:30 PM at the Everett Firefighters Association. Representatives from the FHWA, and the Forest Service were available to answer questions and receive comments.
