To address the problems beforehand, Gordon led the citizens of Olongapo to mobilize and lobby for the inclusion of a free port concept into the national legislation for the conversion of the U.S. bases. The effort was successful, with the inclusion of the establishment of the Subic Bay Freeport Zone (also known as the Subic Special Economic Zone) in Section 12 of Republic Act No. 7227, otherwise known as the Bases Conversion and Development Act, which was approved on March 13, 1992. Section 13 of the same legislation also provided for the establishment of the Subic Bay Metropolitan Authority (SBMA), which was tasked to administer the Subic Bay Freeport Zone.
