STATE ENVIRONMENTAL POLICY ACT WAC 197-11-970 Determination of Non-Significance

Agency File Number(s): SEPA 2023-01 City of Dayton Shoreline Master Program (SMP) Periodic Review

Applicant: City of Dayton/Clark Posey, 111 S 1^st St., Dayton, WA 99328

Project Description: The City of Dayton is proposing updates to the SMP in coordination with Ecology as part of the Shoreline Management Act (SMA) Periodic Review process. The SMP establishes standards for shoreline development. The state SMA requires each jurisdiction with shorelines of the state and shorelines of statewide significance to make and update these rules. The City is proposing to adopt the revised SMP as an update to its 2017 SMP in spring 2023. Proposed amendments to the existing 2017 SMP may be reviewed at https://sewashingtonsmp.com/

Location of proposal: The updated SMP will apply to all waterbodies under SMA jurisdiction within the City, including floodways; land within 200 feet of the ordinary high water mark (OHWM) of the waterways; and associated wetlands. The SMA regulated waterbody in the City is the Touchet River.

Threshold Determination: The lead agency for this proposal has determined that it does not have a probable significant adverse impact on the environment. An environmental impact statement (EIS) is not required under RCW 43.21C.030(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency.
