Research notes

GSMNP is the most-visited US national park (~12M annual visits) spanning Blount (FIPS 47009), Sevier (47155), Cocke (47029) counties in TN. Sevier County zoning resolution (227 Cedar St, Sevierville) flags park-adjacent A-1 / RR campground proposals for low-impact design preference. No state-level overlay; preemption operates via federal NPS authority over the park boundary and Section 106/NEPA over federally-nexused adjacent projects. Pigeon Forge, Gatlinburg, Townsend have local view-corridor / scenic-overlay treatments tied to park adjacency.
