Core frame model

In the core frame model showing the structure of the center of the city, the zone of transition encircles the central business district (CBD). It includes a zone of assimilation where the buildings are being drawn into CBD usage. There may also be a zone of degradation where the buildings are changing from CBD usage to residential land use.

It is characterized by residential deterioration and encroachment by business and light manufacturing.[1]
