1 Multiple Nuclei Model Ch 13.
A model of town growth by C. D. Harris and E. L. Ullman 1945

3 Multiple Nuclei Model Distinctive land-use zones develop because some activities repel each other high-quality housing does not generally arise next to industrial areas other activities cannot afford the high costs of the most desirable locations.

4 New industrial areas develop in suburban locations since they require easy access
outlying business districts may develop for the same reason. Transportation improvements allowed for deconcentration

5 Some cities or conurbations have engulfed surrounding settlements or have evolved strong suburban areas around the periphery of the city. Both of these situations cause the 'suburbs' to function as small independent business districts with their own shops and businesses away from the main urban center.

6 Key factors leading to a multi nuclei model:
need for increased accessibility to a center (not necessarily the CBD) to keep conflicting or competing land uses apart (eg. high cost housing and smoky factories) decentralization differences in land values

7 Examples of nodes (nuclei)
An airport will attract hotels and warehouses to store items to be shipped by plane. A big mall will attract apartments and smaller strip malls. A college will attract bookstores and pizza restaurants. A middle class residential area will attract supermarkets.

8 Examples of multiple nuclei
