practice.

Land use may also be formally regulated by land use planning

through zoning and planning permission laws, or by private

agreements.

Land Use PlanningPlanning of a region or a town according to the use ofland. Important tool for making development plan or

master plan.Following are the considerations taken into accountwhile preparing a land use plan:

(1)Area allocation:Area allocation for residential,

commercial and industrial areas are decided dependingon the city and its activities.

(2)Central Business District (CBD):Location of centralbusiness district is decided and if it is to be shifted fromthe existing place, its implications are considered.

(3)Demography:Population and demography index areimportant factors while deciding about residential,commercial and industrial areas.


6/26

(4) Land market:Land prices are determined froma land use plan. Land use plan can be ameasure to control land prices and also a

reason to increase land prices.(5) Location:location for industry, commercial and

residential areas are considered while making aland use plan.

(6) Natural elements orresources:Location ofnatural resources like river, sea, hills, lakes, etc.are considered. Also mines, chemicals and otherresources are identified before preparing a landuse plan.

(7) Topography:Topography of the region i.e.hills, slopes, etc. are considered.

ZONINGIt is defined as the regulation by law of the use of land or buildings and

of the height and density of buildings in specific areas for the purpose of

general welfare of the community. (securing convenience, health, safety).

OBJECTIVE OF ZONING

Town planners---------------opportunities for designing the future growth

and development.

It sustains proper co-ordination of various public amenities like transport,

drainage, power etc.It makes town planning scheme effective and successful.

PRINCIPAL OF ZONING

1. Arrangement of zones2. Boundaries

3. Existing towns

4. Flexibility

5. New towns.

BLOCKS OF UNITS OF VARIOUS USES IN

DIFERENT PARTS OF TOWN.


10/26

2. BOUNDARIES:

Boundaries for different zones are made carefully.

Streets and roads are not given separate boundaries.

Railway line or park or any open space may be demarcated .

3. EXISTING TOWNS:

Existing use of land is gathered, zones divided as per existing use.

Existing land is only altered, if there are substantial grounds.

4.FLEXIBILITIES:

Zoning should be rigidly enforced.

Care taken in working out the details for zoning.

Eg. The work area should be near the residential area( reduces time travel), and

not as close as to be disliked by the residents.

And the flexibility of providing day to day shopping stores in the residential areas.


11/26

5. NEW TOWNS:

Towns should be divided in to suitable zones and their areas should be worked out.

ADVANTAGES OF ZONING:

1. Danger from fire:

Minimum chances and damage due to fire.

2. Future development:

Controlled future development and proper regard to the community welfare.

3. General amenities:

Like parks, playgrounds, cinemas, shopping centers etc. in the surroundings of the main

zonings.

4. Health of community:

Eg. Zoning of industries away from the residential areas. no bad odor or harmful gases.

5. Population distribution:

It regulates the density of population.


12/26

6. Public utility services:

Economic use of water supply, drainage and telephone lines etc.

ASPECTS OF ZONING:

1. Density zoning.

2. Height zoning.

3. Use zoning.

DENSITY ZONING:

It is the density of population in the residential areas controlled by means of suitable

rules and regulations.

Standards:

o The front and rear margins from boundaries are specified.

o Minimum height of building is specified.

o No. of houses per unit area is specified.

o Ratio of total site area to the total built up floor area is specified.


13/26

It is either expressed in gross density or in net density.

Gross density : average density of population

unit area of the whole residential zone.

Net density: avg. density of population

unit house area inc. local roads & excl. open spaces, shopping centers etc

Advantages :

Facilitates the proper layout and designing of various public amenities and services.

Ensure enough light and ventilation to residences.

No overcrowding.

Land values are stabilized.


14/26

HEIGHT ZONING:

Done for: enough daylight to buildings

Reasonable traffic movement.

Height is controlled by:

o bulk and cubical content of building (open and built up area)

Done by volume of building = 1/3 X plinth area X height.

o Street width and other adjacent marginal open spaces (good light and

ventilation).

Ratio comes out to be 2:1. (Height: width)

ADVANTAGES:

Solves the traffic and population congestion problem.

It is observed that building with uniform height constructed on important roads and

streets, give pleasing appearance.

Good light and ventilation.

Land value goes high in certain areas only.


15/26

USE ZONING:

Defines the use to which various parts of the town will be put.

Categories:

Residential zone. (40% - 50%)

Commercial zone. (2% - 5%)

Industrial zone. (2%- 25%)

Recreational zone. (Remaining)

Residential zoning:

Factors: * nearness to the market.

* freedom from nuisance , noise, smoke.

* nearness to parks and playgrounds.

Classification: *detached house

*semi- detached houses.

*row houses

*flats

*skyscrapers.

I l d *h i


16/26

Includes: *housing

*urban streets

*convenient access to work areas etc.

Location: *windward

*upstream with respect to industrial zone.

COMMERCIAL ZONE:

Near the centers of traffic

Abutting the roads.

Includes, land for banks, offices, godowns, shops etc.

INDUSTRIAL ZONE:

Light industries: can be set near to residential zone (no noise)

Heavy industries: outskirts of town ( production of harmful fumes, gases etc.)Minor industries (laundries , bakeries, dairies): grouped to serve best to surrounding

areas.

Special industries ( producing undesirable trade waste and by products): located far

away from ground in spacious grounds.

Industries with large freight turnovers: connected to railways, ports etc.


17/26

RECREATIONAL ZONES:

Includes, parks, play grounds, cinemas, theatres, clubs, libraries, restaurants,

stadium and other community needs.

These zones are scattered throughout the plan of town.

ADVANTAGES OF USE ZONINGS:

Each zone should permit the best use of land.

Enables proper selection of sites for community needs( schools, hospitals, colleges

etc.)

Determine in advance size of transport facilities and other amenities.

Stabilization of land values.

MASTER PLAN

"A Master Plan is the long term perspective

plan for guiding the sustainable planneddevelopment of the city. This document

lays down the planning guidelines,

policies, development code and space

requirements for various socio-economic

activities supporting the city population

during the plan period. It is also the basis

for all infrastructure requirements."


19/26


20/26

Is defined as a general plan for the future layout of a city showing both the

existing and proposed streets or roads , open spaces , public buildings etc.

It is prepared either for the improvement of an old city or for a new town to bedeveloped.

It aims at controlling the future growth of a town along preconceived and

predetermined paths.

it should be sufficiently elastic , so that it is possible to amend it from time to

time to keep it in pace and to accommodate new developments.

OBJ ECTS OF A MASTER PLAN

aims at economic spending of the public funds for the welfare of the

inhabitants in respect of amenity , convenience and health.

Arranges the pattern of a town in such way so as to satisfy the present

requirements .

Helps in restricting the haphazard and unplanned growth.

Places various functions which a town has to perform in physical relationship

of each other so as to avoid the chances of mutual conflict.

Serves as a guide to planning body for making any recommendations for public

improvement.


21/26

NECESSITY OF A MASTER PLAN

To control the development of various industries in a systematic way.

To discourage the growth of the town in an unplanned and unscientific

way. To limit to a certain extent the unprecedented flow of rural population

to the urban area.

To offset the evils which come up due to the overcrowding of

population such as acute shortage of houses, traffic congestion,

inadequate open spaces, insufficiency in public amenities.

FEATURES OF A MASTER PLAN

Convenient and cheap means of transport.

Good sanitation and water supply.

Open air spaces

Population density control

Places of worship , education and recreation.

Rational layout

Width of roads.


22/26

PLANNING STANDARD

The term planning standard is used to fix the minimum area for eachuse for a certain population or for a certain land area.

These minimum standards are fixed for a particular locality by

studying the functional requirements , number of users , open spaces

required around the buildings, social and climatic conditions,

economic activities of the locality etc. The planning standards are fixed for various types of uses such as-

- educational facilities

- medical facilities

- miscellaneous amenities such as burial ground , police

station , post office, petrol station , fire station etc.- width of the roads


23/26

STAGES OF DEVELOPMENT OF A MASTER PLAN

Collection of data and relevant information from civic survey and other

sources. Preparation of a tentative draft of the development plan and notifying

the same for comments from experts and public.

Consideration of views received from experts and the public

Preparation of the revised plan accommodating good aspects of

comments received from experts and public.

Determination of the sequence in which the development plan will be

implemented.


24/26

FLOOR AREA RATIOIn the field of zoning, floor area ratio refers to a limit on how much totalspace, expressed as a fraction of the total size of the plot of land involved,may be consumed by the floor or floors of a building or buildings

constructed on the plot.Also known as FLOOR SPACE INDEX (FSI)

For example, if the relevant zoning ordinance permits construction on aplot, and construction must adhere to a .1 floor area ratio, then the totalarea of all floors in all buildings constructed on the plot must be no morethan one-tenth the area of the plot itself.

AREA TO BE COVERED ON GROUND = GROUND COVERAGE X TOTAL PLOT AREA

TOTAL AREA TO BE USED ON ALL FLOORS = F.A.R. X TOTAL PLOT AREA

NO. OF FLOORS = TOTAL AREA TO BE USED ON ALL FLOORS

AREA TO BE COVERED ON GROUND


25/26

FAR = Total built - up area / Total plot area

Typically, the calculation of area consumed combines the total area ofall floors, thus uniting horizontal dimensional limits with vertical

dimensional limits into a single parameter.

A builder can plan for either a single-story building consuming the entireallowable area in one floor, or a multi-story building that rises higherabove the plane of the land.

By combining the horizontal and vertical limits into a single figure, someflexibility is permitted in building design, while achieving a hard limit onat least one measure of overall size.

The FAR within each city varies depending on the location.

The total construction as declared in the plans offered by the promotershould not exceed the FAR permissible for the end-use zone in whichthe plot lies.


26/26

SUBDIVISION REGULATIONS The purpose of these regulations is to guide the development of the

new areas in accordance with the land use plan.

Avoid the necessity of costly corrective measures needed if sub-standard growth is allowed to take place.

It is confined to standard for street width and community facilities which

are laid down as according to the density.

Refers to the division of land into two or more plots for the purpose of

sale or building development.

It is a process of converting raw land into building sites.

It is a useful legal tool for taxation, registration of plans, accurate land

records.
