SeaTac and King County
SeaTac is associated with King County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
SeaTac by land and water
The Census records 0.18 square miles of water within SeaTac, or 1.7% of its total area. It is 6.6 percentage points lower than the 8.3% recorded for King County. This is geographic context; waterfront status and usable land must be checked at the parcel.
