SAN JUAN, Puerto Rico (AP) — Legislators in Puerto Rico are investigating coastal erosion across the U.S. territory and its impact on tourism.

The island's Senate said in a statement Saturday that an electrical substation on the sister island of Vieques had to be relocated because of erosion. Lawmakers noted that two of three gazebos built to accommodate tourists on Vieques also had to be removed.

The U.S. territory is already partnering with the U.S. Army Corps of Engineers for a $120,000 project to study the movement of sand along the island's northern and western coasts.
