The existing project consists of an entrance channel (860 feet long, 120 feet wide, 12 to 15 feet deep); a 1.2-acre turning basin (12 feet deep); a main access channel (540 feet long, 80 feet wide, 10 feet deep); a revetted mole (1,135 feet long); an east breakwater (200 feet long); a west breakwater (525 feet long); a 250-foot long wave absorber and three circulation channels. The harbor was designed to provide berthing areas for up to 300 boats. The local sponsor is the Port Authority of Guam.
