1. Presented By Avishek Das THE MULTIPLE NUCLEI MODEL BY C. D. Harris and e. L. ullman WELCOME

2. THE MULTIPLE NUCLEI MODEL The Multiple Nuclei Model was created in 1945 by C. D. Harris & E. L. Ullman . This model was based on Concentric Zone Model & Sector Model. The model to no one’s surprise describes the layout of a city based on Chicago.

3. Concept :- “ Multie Nuclei Model” is a Model of urban Land use in which a city grows from several independent points rather than from one central business district. This model was given in an article by them “The Nature of Cities” . Each point acts as a growth canter from a particular kind of land use , such as industry ,retail,port,university or high quality housing ect. As this expand , the marge to from a single urban area. The CBD is not the only generator of change. Example:- London,Chicago,Los Angeles etc.

4. -: ASSUMPTION :- Land is not flat is all areas. Even distribution of resources. Even distribution of people in residential areas. Even transportation costs.

5. -: ZONES :- Central Business district (CBD) Wholesale Light Manufacturing Low Class Residential Medium Class Residential High Class Residential Heavy Manufacturing Outlying Business Area Outlying Residential Outlying Industrial Area

6. Central Business district (CBD ) :- The CBD still exists as the primary nucleus, but multiple small business districts developed, distributed around the metropolitan area. Some of these newer areas compete with the CBD for traditional businesses like banks, real estate and insurance companies. Wholesale Light Manufacturing :- These businesses are more consumer-oriented and near residential areas. Manufacturing goods that need small amounts of raw materials and space develop in this area. Low Class Residential :- Next to the industrial corridors are the lower- or working-class residential zones. People who live here tend to be factory workers and live in low-income housing.

7. Medium Class Residential :- This residential area is a bit more desirable because it is located further from industry and pollution. People who work in the CBD have access to good transportation lines, making their commute easier. The middle-class sector is the largest residential area . High Class Residentia :- High-class residential sectors tend to be quiet, clean, and have less traffic that the other ones. Heavy Manufacturing :- This node is occupied by factories that produce material that is heavy like chemicals, steel, industrial machinery. Mining and oil refining industries also can be found in this node

8. Outlying Business :- This district competes with the CBD for residents who lived in nearby middle and high-class neighborhoods offering similar services and products as the CBD. Businesses found in this node are malls, airports, colleges and community businesses . Outlying Residential Area:- These residential areas are usually single-family homes on a small plot of land on the outskirts of the city. They tend to be laid out on roads with cul-de-sacs instead of following the traditional grid pattern. Industrial Area :- This is a community created and zoned for industrial sources on the outskirts of the city.

9. -: CRITICISM :- Not an exact fit for all cities and towns. Too complex. Not applicable to oriental cities with different cultural economic and political backgrounds. Negligence of height of buildings. Not even distribution resources. Non-existence of abrupt division between zones.

10. -: Are this model relevant to today’s Cities :- Delhi somewhat conforming to the Multiple Nuclei Model
