Barangay extraterritoriality disputes
Global Marine System's territory is part of Barangay San Roque. It is an enclave within Barangay San Andres 1. Notably, ICTSI's Bauan International Port disputes the boundary of Barangay San Andres 1 and San Roque, due to some land of ICTSI is actually inside San Andres 1. This is verified by residents of the Ilaya part of San Andres 1. Currently, residents do not know the location of the boundary between the two barangays.
