Steilacoom Washington is the oldest incorporated town in Washington state and sits on the Puget Sound adjacent to Joint Base Lewis-McChord. The community hosts Western State Hospital — the primary state psychiatric facility — and the Steilacoom ferry connection to Anderson Island. JBLM's proximity creates military community considerations and Pierce County earthquake risk is significant.
