Research notes
Coastal geographic preemption applicable to Long Island, NYC (Staten Island, south Brooklyn, Queens, Bronx), and Westchester. federal_conflict_check=true because state tidal-wetlands jurisdiction overlaps with federal Clean Water Act §404 (USACE) and the NY State Coastal Management Program (NOAA CZMA).
