Many environmental agencies across the state are working to stop the construction of a terminal groin on the north end of Figure Eight Island.
A terminal groin is basically a wall built in the water to prevent erosion.
Homeowners on the island say it will save the beach.
But environmental experts say there are better ways to keep sand on the island.
"It would be expensive, costing millions of dollars to build; it would be destructive because it would destroy the naturally functioning rich inlet and the habitat here, and it's unnecessary because there are other ways to address erosion on the beach that would not require building this rock wall," Derb Carter with the Southern Environmental Law Center said.
Experts say channel relocation would be a much better option claiming it's cheaper and more environmentally friendly.
