Project Name: Smith Island Dredging Project Number: RR49206-DD5
Project Description: Snohomish County Public Works is proposing the Union Slough 10-Year Maintenance
Dredging Program in Union Slough near Smith Island in unincorporated Snohomish County, Washington.
The upstream and downstream limits of the project area are between the Buse Cut and the Buse Timber
log ramp, respectively. To maintain navigation, the Project proposes maintenance dredging of up to
100,000 cubic yards of sediment over a 10-year period to address the potential accumulation of sediment
resulting from the 2018 removal of portions of the Smith Island diking system that occurred as part of the
Smith Island Estuary Restoration Project. Maintenance dredging would occur if sedimentation exceeds
an elevation of -2.5 feet North American Vertical Datum of 1988 (NAVD88). Dredging would occur to a
maximum existing depth of -8.5 feet NAVD88, with a 2-foot allowable overdredge to -10.5 feet NAVD88.
Maintenance dredging would be scheduled as necessary. The preferred disposal method for the sediment
is at the Port Gardner Open-Water Disposal Site located between the City of Everett and Whidbey Island.
Alternatively, the material could be temporarily stockpiled behind the new setback dike, before being
transferred to an upland disposal facility.
Project Location: The project sites are located in Sections 3, 4, 9, and 10, Township 29 North, Range 5
East, W.M.
Type of Project: Maintenance dredging.
Permits/Approvals Required: Shoreline Substantial Development Permit Exemption, Shoreline Conditional
Use Permit, Land Disturbing Activity Permit and other applicable federal, state and local permits.
SEPA Decision: On March 5, 2019, Public Works determined that this project does not have a probable,

significant adverse impact on the environment and has issued a Determination of Non-significance (DNS).

An environmental impact statement (EIS) under RCW 43.21C.030(2)(c) is not required. This decision was

made after review of a completed environmental checklist and other information on file with this agency.

Project Comment Period: Submit written or e-mailed comments on or before 5 p.m., Monday, April 1, 2019.
SEPA Appeal Period: There is no opportunity for appeal at this time. Pursuant to SCC 30.61.300(10),
SEPA appeals related to a shoreline conditional use permit, which is a Type 1 decision, shall be submitted
to the state Shorelines Hearings Board together with appeal of the underlying permit.
