King County Shoreline Master Program: Limited Amendment

On April 5, 2017, the Department of Ecology approved King County’s Limited Amendment to the Shoreline Master Program (SMP). Per RCW 90.58.090, the effective date of King County’s limited SMP amendment is April 19, 2017, 14 days after Ecology provided notice to the County that their shoreline program was approved.

This SMP Limited Amendment includes modifications to sections of their Critical Areas regulations (King County Code 21A.24) incorporated into the SMP and to the County’s Shoreline Master Program regulations (King County Code 21A.25), as identified in portions of two (2) separate local actions: Ordinance 17539 from 2013 and Ordinance 17841 from 2014. This amendment modifies uses and activities allowed within the shoreline jurisdiction, including changes in allowed uses and modifications within critical areas. Additionally, this amendment acknowledges Ordinance 17878, which establishes authorization for up to five (5) alluvial fan management demonstration projects within the shoreline jurisdiction of the Snoqualmie River watershed basin per KCC 21A.55.

A public comment period was held from November 29 – December 30, 2016. Ecology used mail and email to notify interested parties of the public comment period. Ecology also sent out a news media email tip to encourage additional public participation and comment. We received one comment from the Snoqualmie Tribe focused on implementation of the alluvial fan demonstration projects and requesting that any new ordinance prohibit subdivisions with lots that would require a shoreline variance for future development. The public comments and responses have been incorporated into Attachment A: Findings and Conclusions (below).
