The Washington State Environmental Policy Act of 1972 (SEPA) was designed to reduce or eliminate environmental impacts. SEPA environmental review is necessary for many King County Water and Land Resources Division (WLRD) proposed actions, especially capital improvement projects.

Information provided and gathered during the SEPA review process helps decision-makers, project sponsors, and the public understand how a proposed project will affect the environment. The SEPA process is intended to ensure that environmental values are considered during project development.

As a lead agency, WLRD assesses its proposed projects and programs to determine if any significant adverse environmental impacts are likely, and if so, potential mitigation is identified. A determination of nonsignificance is issued when WLRD has determined that a proposal is unlikely to have significant adverse environmental impacts, or mitigation has been identified within the project that will reduce impacts to a non-significant level.

The projects highlighted below are designated WLRD SEPA lead agency projects currently undergoing environmental review.

Opportunities for public review and comment

SR 169 Flood Risk Reduction Project

The SR 169 Flood Risk Reduction project will reduce the risk of flooding and unpredictable closures of SR 169 northwest of Cedar Grove Road and reduce the risk of isolation or flooding of nine residences in the immediate vicinity. This flood risk reduction project replaces culverts that are fish passage barriers with larger culverts that minimize flood risk and allow salmon access to potential upstream habitat. The project is in cooperation with WSDOT and is compatible with long-term goals to widen SR 169.

Comment Period: The public comment period for this project is open from Jan. 22, 2020 to Feb. 5, 2020.

Notice of Action: A determination of no significant impact was made on January 14, 2021.

Stuck River Drive Revetment

The Stuck River Drive Revetment Repair Project will replace missing toe rock along the entire length of damaged revetment (approximately 180 feet) located on the left bank of the White River at River Mile (RM) 7.9. Repairing the damage as soon as possible will reduce the likelihood of further damage to the facility and reduce risk to the adjacent White River Trail and Stuck River Drive road.

Comment Period: The public comment period for this project is closed. The initial comment period was June 12, 2020 to June 26, 2020. Public comments received are available below.  

Notice of Action: A final determination of no significant impact was made on June 20, 2020.

Linda Bartolini-Venegas, Project Manager


Shake Mill Right Bank

The Shake Mill Right Bank Levee Repair Project will repair approximately 80 feet of damage on the levee, located at River Mile 0.3 on the right bank of the North Fork Snoqualmie River. There are several locations, between the mouth of Tate Creek and the North Fork Bridge, with erosion and dislodged toe-rock; repairing the damage as soon as possible will reduce the likelihood of further damage to the facility and reduce risk to King County transportation infrastructure.

Comment Period: The public comment period for this project is closed. The initial comment period was May 1, 2020 to May 15, 2020, and no public comment was received.

Notice of Action: A final determination of no significant impact was made on May 20, 2020.
