St. Marys' position at the Georgia-Florida border means both Georgia and Florida DEP environmental requirements may apply depending on exact waterfront location.

Most St. Marys seawall repairs using polyurethane injection or helical tiebacks are completed in 1–2 days. We schedule work around low tide windows for maximum access and accuracy.
