Determination of Non-Significance (DNS)

Seattle Parks and Recreation (SPR) is proposing to replace the existing concrete boat ramp and extend two existing boat ramp piers, at Stan Sayres Memorial Park, with new gangways and floating dock sections. SPR has determined that it does not have probable significant adverse impact on the environment. An environmental impact statement 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 SPR. This information is available to the public on request.

This DNS is issued under 197-11-340(2); SPR will not act on this proposal for 14 days from date of publication (11/5/2018).
Comments must be submitted by November 20, 2018. The appeal period ends November 28, 2018.
