The state Supreme Court unanimously reversed a lower court ruling that had stopped a referendum to consider repealing a revised zoning ordinance passed by McIntosh County officials two years ago. Residents of Sapelo Island opposed the zoning amendments that doubled the size of homes allowed in a tiny enclave called Hogg Hummock. But attorney Dana Braun, who represents the Hogg Hummock residents, said the ruling will give county residents “some real say” in whether they support the zoning change. In 1996, Hogg Hummock earned a place on the National Register of Historic Places, the official list of treasured U.S. historic sites. The state Supreme Court was not weighing whether Hogg Hummock deserves special protections.
