Research notes

Gulf Islands NS spans Mississippi (Ship, Horn, Petit Bois, East and West Petit Bois, Cat Island; Davis Bayou mainland district in Ocean Springs) and Florida (Santa Rosa, Perdido Key). MS unit comprises ~135,000 acres mostly submerged. Adjacency review applies to Ocean Springs, Biloxi, Pascagoula, Gulfport, and unincorporated Jackson/Harrison/Hancock county parcels. No state-level overlay; preemption operates through federal NPS authority over the seashore boundary and §106/NEPA over federally-nexused adjacent projects.
