The Aldan plan (1990)

The problem of illegal construction in the late 80s, combined with the introduction of the Metropolitan Municipality Law and changes to national zoning regulations such as Zoning Law 3194 (both giving cities increased authority in urban planning as opposed to the central government), necessitated an updated city plan. This plan, the fourth one in Gaziantep's history, was drafted in 1990 by H. Oğuz Aldan. The Aldan plan had a target year of 2005, with a predicted population of about 1.8 million. It planned for the city to expand to 8010 ha, of which 26% would be residential, 22% would be industrial, and 17% would be open green spaces.

The Aldan plan followed a metropolitan, polycentric model, with new commercial zones mixed in with the residential areas to serve as secondary urban centers. The main directions for new development were toward the west and south. A new ring road on the east, south, and west helped boost growth in these directions. Some of the new secondary centers were built in the Karataş and İbrahimli areas. Another major addition was a new commercial area on the east side of the city called the Gaziantep Ticaret ve Endüstri Merkezi (Gaziantep Trade and Industry Center), or GATEM for short. Located on the Araban-Adıyaman highway, on the city's outskirts, the GATEM was to occupy 40 ha and also include an intercity bus terminal.
