M.PLAN – URBAN PLANNING [2013 – 2015]

A STUDY OF RURAL SETTLEMENT – AMOOR VILLAGE

Background: Rural development is necessary not only

because the over whelming majority of the country’s

population lives in villages but also because the

development of rural activities is essential to accelerate the

place of overall economic development of the country. The

primary task is to migrate the hunger of about 70% of the

population to provide adequate clothing, a clean house and

clean environment, medical care, recreational facility,

education, transport and communication.The growth rate of

these basic needs has been growing at an average annual

growth rate of 3, 4% between 1951 and 1981. There is much

evidence to show that public interest in rural development

is growing rapidly to carry the benefits of development of

India’s 5,75,000 villages and improving their living

standards, particularly of those living below poverty line.

About Amoor Village:

Amoor village located at Manampathy Block, Thiruporur

Taluk

It was 54km away from Chennai District and 19km from

Chengalpattu

A STUDY OF URBAN SETTLEMENT – LITTLE MOUNT

Background: An urban area is a location characterized by

high human population density and vast human-built

features in comparison to the areas surrounding it. Urban

areas may be cities, towns or conurbations, but the term is

not commonly extended to rural settlements such as

villages and hamlets. Movement in urban settlements is

typically available due to presence of an elaborate transport

system of taxis, buses and trains. People and goods can be

transported easily without incurring high transportation

costs. Urban settlements are home to job opportunities in

different industries and offices. Wages in urban settlements

are higher than in rural areas, which attracts many people

to towns. Employment in urban settlements is

complemented by affordable housing services in towns.

Urban settlement attracts diversified groups looking for

employment and social services. This diversity leads to

exchange of cultural ideas and beliefs. This study was

mainly conducted to understand the urban characteristics

and how to make them more effectively.

About LITTLEMOUNT

Little Mount (Chinnamalai) is a small hillock that lies on

the bank of river Adayar in the Saidapet taluk of

Chennai

Little Mount now is a bustling area with a mix of

residential and commercial activities..

About LITTLEMOUNT

IX Metropolitan Magistrates (Saidapet) court, Saidapet

MTC bus depot, and All India Radio are located in Little

Mount. Other Governmental offices such as Raj Bhavan

(Governor's house), Highways Department, Panangal

Maligai are located at the borders of Little Mount.

Current development in and around Little Mount

include New Life Assembly of God (NLAG) Church,

Checkers Hotel, Lemon Tree Hotel, Temple Steps Office

Space. METRO line from Alandur to Chamiers road will

have a station at Little Mount.

DEVELOPMENT PLAN FOR HOSUR

Background: Any town has to perform as an engine for

growth to its surrounding areas. It has the pressure to

function and perform at higher levels in all spheres of

activity. A Development Plan aims at elevating the town to

such level by assessing the needs and issues and providing

strategies for developments and proposals for the same.

The context of a Development plan is basically an idea to

prepare a medium plan for a medium urban settlement. It is

a policy document that sets out policies and reforms for the

optimum use of resources in the Planning area.

As a part of II semester, Planning Project II, the

Development Plan for HOSUR – 2014 to 2034 is prepared.

Generally, the Development Plan is prepared for a plan

period of 20 years. In this case, 2031 is taken as the cut off,

as it is the census year for projection of population and

other requirements

DISSERTATION – COMPACT CITY [HIGH DENSITY WITH

MIXED USES

Background: A compact city is an currently emerged urban

planning concept . Promotes relatively High density with

mixing of various activities. It provide required infrastructure

facilities with in the walkable distance. It is otherwise called

as “City of Short distance”

Compact City – View of Authors

Elkin (1991) said Compact city is the “Intensification of

the use of space in the city with higher residential

densities and centralisation”

Newman and Kenworthy(1989) said “More intensive

land use, Centralised activities and higher densities”

Breheny (in Blowers, 1993) said “High density, mixed use

city, where growth is encouraged within the boundaries

of existing urban areas , but with no development

beyond its periphery”

General characteristics of compact city

Efficient usage of scarce land

Reduces travel time between office and home

Low wastage of precious sub-urban agricultural land

Saving in per-capita infrastructure spending

Lower per capita pollution

Enables faster execution of planned development

Integrated approach to solve the social problems arose

24



Why we need Compact City?? Components – Compact City

Objectives

Various concepts involved in the compact urban form.

Effectiveness of mixing of activities to achieve the high

density.

To assess the applicability of compact city concept in

Indian context

High density with mixed land uses.

Interconnection of streets and transport corridors with a

focus on pedestrian, bicycle and public transport

oriented planning.

25



2. Compact city planning along the LRTS corridor in London

Inferences

The intensification and development along the

transit corridor is the major strategy

To make a city with higher density with high rise

and mixed uses they go for sky scrapers and

verticality.

Transportation plays an important role.

The urban compact form of Hong Kong mainly

reduce the ¼ to of the travel time.

Intermingling of functions mainly based on the site

characteristics and potentials.

Through urban densification they achieved the

maximum density of 9,600 habitants per Sq.Km and

2,048 families per Sq.Km.

CASE STUDIES

1. Compact High density development in Hong Kong, China

Mei Fu Shan Chuen city development Hong Kong, China

Metro-City Residential Development, Tseng Kwan O,

Hong Kong, China

Inferences

In London they integrate urban areas, Through urban

renaissance and intensification they achieved high

density in the core areas by intermingling of activities

Transportation plays an important role in the

intensification process

(E.g.) Barbican in London has a land area of 22.4 ha, 16

ha of which is residential, accommodating 6,500 persons.

The gross density is 290 persons per ha, and the net

density is 406 persons per ha. And also they created

6500 new jobs. These developments are well connected

by the public mode of transportation.

26



In this conceptual plan the transportation(LRTS)

plays an important role to make the city as more

compact. Along LRTS corridor they have identified

certain nodes.

These nodes are either stop or stations. Around

the nodes they brought the compact development by

declaring some zonal regulations.

3. Compact city policies Amsterdam, Netherland

Inferences

Urban densification process effectively done in that area

through clustered development. The commonly adopted

strategies are

Along public transport truck routes in order to support

public transport thresholds

In and around urban nodes and modal interchanges/public

transit stops

On the periphery of open spaces to increase surveillance

Within areas of focused high private-sector investments

Transportation play a vital role in the city development.

Mixing of activities done after analysing the site

characteristics.

Through densified clustered development results maximum

population density of 400 to 500 persons per hectare and

75 to 100 dwelling units per hectare.

27



4. Compact high density development Curitiba ,Brazil

Interrelationship between Landuse, Street Network & Public

Transit

Inferences

Urban densification process effectively done.

Transportation play a vital role in the city development.

Mixing of activities done after analysing the site

characteristics.

Increasing Floor Area Ratio maximum 6 around the

transit nodes is the one option for densifying an urban

settlements.

Through densification they have achieved a maximum

density.

Effective utilisation of existing infrastructure facilities.

5. Compact high density development, Ahmedabad, India

Jammarg Bus Rapid Transit

system was introduced in the

year 2009 span of 220

kilometres

Phase I--45 kms

Phase II--currently under

construction, adds another

58.0 kms.

Phase III proposes adding an

additional 40.2 kilometres.

Daily ridership increased by a

factor of 10 in two years, from

13,000 in October 2009 to

135,000 in November 2011

28



Naturally Ahmedabad has compact structure.

The AUDA decided to intensify in and around the nodes.

Minimum lot size of 1500m to 2500m

100m of the road is zoned as high intensity

development zone with FSI 4,

Up to 250m is also intensification zone with FSI 3

Rest of the city to get FSI 2.75

Applicability in Indian Context

India is one of the fast developing countries in the world.

It has about 18% of the world’s population.

Vast growth of existing metropolitan cities results

scattered developments(e.g.)Bangalore, Chennai,

Mumbai etc.,

Resulted in lack of matching infrastructure, large share of

slums in cities, traffic congestion, and disparities in

access to urban services, lack of land availability,

pollution and degraded natural environment in cities

So Compact urban development is the best solution to

meet growing housing demand

Conclusion

It is safe to say that the future of India lies in its cities.

especially Smaller cities can adopt compact cities from

scratch and restrict urban sprawl so as to control

environment and ecological degradation

Strong political will and support from citizens is also the

integral to the success of compact cities.

The Government should also encourage it.

The major step toward achieving this is by directing the

policies for growth

Best of the Best: We may understand and adopt,

Development control & Management of facilities.

Re Engineering required: Social Inclusiveness, Policies,

Regulations Marketing the approach itself.
