Zoning is a device to regulate land use
planning by local government. It is first used as “practice of designating
permitted uses of land based on mapped zones which separate one set of land
uses from another.” Nowadays, the function of zoning expands to regulate the
building height, lot coverage and some other similar characteristics.

Zoning types in the United States: zoning
codes has changed a lot with the development of urban planning theory,
basically, there are four kinds of zoning codes: Euclidean, Performance,
Incentive and Form-based.
Euclidean is named after the successful zoning
code adopted in the town of Euclid, Ohio. Euclidean zoning codes segregate
different land use into “specified geographic district”. In each district, sets
“standard stipulating limitation” on development
activities.
Performance codes also calls “effects-based
planning”, it uses “performance-based or goal-oriented criteria” to limit every
parcel on a certain proposed development projects.
Incentive zoning establishes “a base level
of limitations and a reward scale to entice developers to incorporate the
desired development criteria”. Incentive zoning attempts to use reward to
encourage developers to meet desired goals.
Form-based codes regulate the type of land use,
even the form that land use may take. It is more flexible than Euclidean zoning
code.

Zoning is very useful way to draw a base map of city before design. However, Jane Jacobs said that zoning simplify a city because it set a big block for just one use. Do you agree with her opinion?
ReplyDeleteI think zoning is a good way to lead people to use its land optimally. I agree that zoning prohibit other use of land, but regulating land use to some extent is necessary, or individual will only apply their land for the best benefit, ignoring the social welfare.
