Research notes

Procedural interface overlay — does not directly preempt local zoning, but development within NPS boundary requires federal consultation and within the state park is governed by IDNR. Task brief mentioned both 'Indiana Dunes National Park' and 'State Park overlays' — captured in one overlay record because the geographic + procedural posture is parallel. Boundary in Lake (18089), Porter (18091), and LaPorte (18127) counties; overlaps the LMCP coastal zone.
