Thread: Two recognised zoning techniques?

  1. #1

    Two recognised zoning techniques?

    Could someone please tell me 2 recognised zoning techniques and also their descriptions?

    It would be in regard to planning a coastal recreation and scientific centre.

    Many thanks for any help.

    I'm not sure what you're driving at, but historically there are three types of zoning ordinances. They are:

    1. Prohibitive - a prohibitive ordinance is one that lists uses that are not permitted. It is presumed that everything that is not prohibited is permitted in that district. This is illustrative of the very earliest zoning ordinances.

    2. Permissive - a permissive ordinance lists all the uses that are permitted within a given district. It is presumed here that everything that is not specifically listed is prohibited in that district. This type of zoning ordinance is the most common type of ordinance.

    3. Performance - a pure performance ordinance would have no districts. It would argue that any two uses are compatible with each other if the correct combination of lot sizes, setbacks, buffers, noise regulations, light regulations, etal are applied.

    Most contemporary zoning ordinances combine the permissive zoning ordinance with element of a performance zoning ordinance. A good example of a performance district would be a floodplain district which states that if you have a residential lot in a floodplain, you can develop that lot as long as you do not obstruct the floodway portion of the floodplain and you floodproof the home by placing it on fill.

    Districts in zoning ordinances are generally structed in two different manners. You may have:

    A. Pyramidal Districts. A pyrimidal ordinance is one where one district - typically the single-family residential district - receives the most protection. It permits only single-family residential homes.

    The two-family residential district permits two-family homes and single-family homes.

    The multi-family district permits apartments, two-family homes and single-family homes.

    The commercial district permits businesses and multi-family, two-family, and single-family homes.

    The pyrimid continues and the industrial district becomes the least protected district.

    B. Exclusive Zoning Districts. Exclusive zoning districts are exclusive unto themselves. Single-family districts permit only single-family uses. Multi-family districts permit only multi-family uses. Business districts permit only business uses. Park districts permit only park uses. This approach recognizes that each class of use deserves the same amount of protection.

    Exclusive zoning districts should not be confused with exclusionary districts. An exclusionary district usual excludes a part of society from areas where they are considered undesireable or unwanted. Exclusionary zoning is usually illegal.
