Shoreline Periodic Update

Press Enter to show all options, press Tab go to next option

The City of SeaTac is conducting a periodic review of its Shoreline Master Plan (SMP) as required every eight years by the Shoreline Management Act (Chapter 90.58 RCW) . SeaTac’s SMP, a land use plan for local shoreline areas, applies to the lakeshore along Angle Lake and 200 feet landward of the lakeshore.

This review is not a major update like the City completed in 2010. Instead, the periodic review is limited in scope to changes that occurred to state laws and rules since the 2010 update. Additionally, the update ensures that the SMP is consistent with other SeaTac plans and regulations.
