Planning Theories Flashcards
Theories of Urban Development
Concentric Circle, Sector, Multiple Nuclei, and Central Place
Concentric Circle Theory
Developed by Ernest Burgess in 1925. Sociologist who studied the growth of Chicago. Cities grow in a series of outward rings, and land use is based on distance from downtown.
5 Rings in Concentric Circle Theory
1) the central business district 2) the industrial zone; 3) the zone of transition, industrial and low-income housing (at one time this ring had high-income, large houses); 4) the zone of middle class housing; 5) the commuter zone, with higher-income housing.
Bid Rent Curve
A theory explaining land use patterns based on how much people are willing to pay for land, in turn, based on the profits that are likely to receive from maintaining a business on that land. Biz in CBD will have highest number of customers, make most money and pays most rent. Needed CCT to make this work. William Alonso
Sector Theory
Developed by Homer Hoyt in 1939. Biz guy from Chicago, real estate development. Disagreed with CCT. Land uses vary b/c of transportation. The city, as a result, was a series of sectors radiating out from the center of the city.
Multiple Nuclei Theory
Developed by Harris and Ullman in 1945. Cities develop a series of specific land use nuclei. A land use nucleus is formed because of accessibility to natural resources, clustering of similar uses, land prices, and the repelling power of land uses.
Central Place Theory
Developed by Walter Christaller in 1933. The theory states that there is a minimum market threshold to bring a firm to a city and there is a maximum range of people who are willing to travel to receive goods and services Also useful as a way of understanding the hierarchy of retail establishments in cities (for example nail salons on every block, a grocery store every 10 blocks, and a large shopping center servicing a much larger area).
Theories of Planning Practice
Rational
Incremental
Mixed Scanning
Advocacy
Transactive
Radical
Communicative
The basic steps in rational planning are to:
Set Goals
Determine Alternatives
Evaluate the Alternatives
Choose an Alternative
Implement the Alternative
Evaluate
What is satisfice?
A term from rational planning. Coined by Herbert Simon. The term accepts that the human mind is limited in its ability to solve problems. We instead choose alternatives that are good enough. Simon argued that the rational “economic man” should be replaced by the “administrative man” who satisfies.
What are the Criticisms of Rational Planning?
Can’t solve wicked problems AND it doesn’t specify WHO sets the goals.
It cannot be used when we have “wicked” problems. Wicked problems are those that are complicated and difficult to solve.
Rational planning can only work when the problem can be easily defined and there can be the best solution.
Rationality is supposed to be value-free. Goals are based on public interest, defined as the good of the whole community. Rational planning should not be used if there is no consensus within a community on a particular issue.
Rational Planning
Rational planning was the dominant planning theory through the 1950s. While this model has been discredited, it can still be seen in use in all areas of the planning practice.
Where does Rational Planning still exist?
In particular, transportation planning is one area in which rational planning persists.
Incremental Planning origin
1959, Charles Lindblom published the article “The Science of Muddling Through”, which introduced the concept of incrementalism.
Incremental Planning
Planning has to be piecemeal, incremental, opportunistic, and pragmatic. Planning in the real world is not rational and comprehensive, but is instead disjointed and incremental.
