“Copiague Harbor is a small, community located on a southern peninsula of Copiague, primarily composed of larger size homes deeded belonging to a homeowner’s association; Great South Bay Estates Homeowner’s Association (GSBEHA). This affluent private community offers amenities including a mini-beach and mini-marina on a private lagoon.
