Latin American Model- Developed by Ernst Griffin and Larry Ford. Blends traditional Latin American culture with the forces of globalization. The CBD is dominant; it is divided into a market sector and a modern high-rise sector. The elite residential sector is on the extension of the CBD in the "spine". The end of the spine of elite residency is the "mall" with high-priced residencies.
African City Model- an informal and sometimes periodic market zone, and a transitional business center where commerce is conducted from curbside, stalls, or storefronts. Vertical development occurse in the colonial CBD, the traditional business center consists of one-story buildings, and the mark zone tends to be informal, yet still important.
Southeast Asia Model- Developed by T.G McGee. The focal point of the city is the colonial port zone combined with the large commercial district that surrounds it. McGee found no formal CBD but found seperate clusters of elements of the CBD surrounding the port zone: the government zone, the Western commercial zone, the alien commercial zone, and the mixed land-use zone with misc. economic activities.
