SAVANNAH, Ga. (AP) — State law requires Jekyll Island officials to count marsh that stands above water at high tide as land when calculating how much of the state park is open to development, Georgia's attorney general said Thursday.

Olens' opinion rejects the conclusion of a task force appointed by the Jekyll Island Authority that said in April that the island long ago overstepped its maximum footprint for development. The group said Jekyll officials for decades wrongly included hundreds of acres of marsh in the island's total acreage as if they were dry land.
