Clarence Perry was an American urban planner from the early 20th century. He is considered a pioneer in neighborhood unit planning. The key aspects of Perry's neighborhood unit model include centering an elementary school in the middle, placing arterial streets along the perimeter, designing a hierarchy of internal streets, and restricting local shopping to the perimeter. The goal was to create self-contained neighborhoods that promoted community and protected residents, especially children, from traffic.

INTRODUCTION: CLARENCE PERRY

3. IDEA OF PERRY’S NEIGHBOURHOOD
The core principles of Perry’s Neighborhood Unit were along
these design ideals:
• Centre the school in the neighborhood
• Place arterial streets along the perimeter so that they define
and distinguish the ‘place’ of the neighborhood.
• Design internal streets using a hierarchy that easily
distinguishes local streets from arterial streets.
• Restrict local shopping areas to the perimeter.

4. IDEA OF THIS NEED
• Earlier idea of Perry was to provide a planning formula for the arrangement and
distribution of playgrounds in the New York region.
• The necessity thought was because of the rise of the auto-mobile in the early
20thcentury.
• Road sense was not proper with the social conscious, thus street fatality rates were
increased.
• Idea was to generate islands locked amidst a wide sea of vehicular traffic, a
dangerous obstacle which prevented children (and adults) from safely walking to
nearby playgrounds and amenities.
• Ultimately, however, it evolved to serve a much broader purpose, of providing an
identity.

5. WHAT IS NEIGHBOURHOOD UNIT?
• Neighborhood “the area within which
residents may all share the common
services, social activities and facilities
required in the vicinity of dwellings”.
• The concept of the neighborhood unit,
crystallized from the prevailing social and
intellectual attitudes of the early 1900’s
by Clarence Perry, is an early
diagrammatic planning model for
residential development in metropolitan
areas.

6. IDEA OF PERRY’S NEIGHBOURHOOD
• The neighborhood unit was conceived of as a
comprehensive physical planning tool, to be
utilized for designing self-contained
residential neighborhoods which promoted a
community centric lifestyle, away from the
"noise of the trains, and out of sight of the
smoke and ugliness of industrial plants"
emblematic of an industrializing New York City
in the early 1900s.

principles of the concept.

7. IDEA OF PERRY’S NEIGHBOURHOOD
• The core principles of Perry's Neighborhood Unit were around these design ideals :
• "Centre the school in the neighborhood.
• Place arterial streets along the perimeter so that they define and distinguish the "place" of
the neighborhood.
• Design internal streets using a hierarchy that easily distinguishes local streets from arterial
streets.
• Restrict local shopping areas to the perimeter.
• Dedicate at least 10 percent of the neighborhood land area to parks and open space.

8. STATISTICS OF NEIGHBOURHOOD UNIT
• Perry described the neighborhood unit as area which require an elementary
school with 1,000 and 1,200 pupils.
• This would mean a population of between 5,000 and 6,000 people.
• Developed with Population Density of 10 families per acre, it would occupy about
160 acres.
• Any child have to walk a distance of around half mile to school.
• About 10 percent of the area would be allocated to recreation, and through
traffic arteries would be confined to the surrounding streets, internal streets
being limited to service access for residents of the neighborhood.
• The unit would be served by shopping facilities, churches, library, and a
community center.

9. ELEMENTS OF PERRY’S NEIGHBOURHOOD
• Residential unit
• Schools
• Shopping centers
• Traffic roads
• Railway stations
• Open spaces

10. NEIGHBOURHOOD PLANNING?
• It is based on the simple principle that one is planning for society and not
for aggregate of houses. The neighbors are not dependent on one
another’s company and aid because city life because city life gives a wide
field of acquaintance and entertainment. The neighbors may not have
common modes and habits of living.
• The neighborhood planning is an attempt to form various physical units of
residential areas in which people belonging to a particular rank of life
settles or stay.
• It is the intention of a town planner to rejuvenate the valuable idea of
neighborhood which have been lost in busy uncontrolled city life.

11. • All the residential units are now planned on
neighborhood principle.
• It is a small unit which serves the local
community and encourages them to foster a
neighborhood spirit or relationship which
seems to have been lost in the modern city
life.
• It should possess the best qualities of small
town to facilitate the acquaintance and
unneighborly relations and also be broad
enough to accommodate sufficient people to
enable each individual to come in contact
with people of different strata of society.

12. PURPOSE OF NEIGHBOURHOOD PLANNING
• To make the people socialize with one and another.
• To enable the inhabitants to share the public amenities and
recreational facilities.
• To support a safe and healthy environment within the
neighborhood.
• To provide safety and efficiency to road users and pedestrians.
• To maintain, enhance, and improve area for recreational activities.
• To determine community’s prospects for the future.

13. PRINCIPLES OF NEIGHBOURHOOD PLANNING
1. Size
2. Boundaries
3. Protective Strips
4. Internal Streets
5. Layout of buildings
6. Shopping Centers
7. Community Centers
8. Facilities

14. FACILITIES PRINCIPLES OF NEIGHBOURHOOD PLANNING
1. Size
• The town is divided into self-contained units or sectors of population.
• This is further divided into smaller units called neighborhood with 2,000 to 5,000 based on the requirement of one primary.
• The size of the unit is therefore limited to about 1 to 1. 5 sq within walkable distance of 10 to 15 minutes.
2. Boundaries
• The unit should be bounded on all its sides by main road, enough for traffic.
3. Protective Strips
• These are necessary to protect the neighborhood from traffic and to provide suitable facilities for developing parks, playgrounds, and
road widening scheme in future. These are called Minor Green Belts.
4. Internal Streets
• The internal streets are designed to ensure safety to the people school going children in particular, The internal streets should
circulate throughout the unit with easy shops and community centers.

15. 5. Layout of Buildings
• To encourage neighborhood relation and secure social stability and balance
• The houses to suit the different income group should be provided single family houses, double family houses, cottages , flats, etc.
6. Shopping Centers
• Each shop should be located on the circumference of the unit, preferably at traffic junctions and adjacent to the neighborhood units.
7. Community Centers
• Each community will have its center with social, cultural and recreational amenities.
8. Facilities
• All public facilities required for the family for their comfort and convenience should be within easy reach.
• These include the primary school, temple, club, retail shop, sport.
• These should be located within 1km in the central place so as to nucleus to develop social life of the unit.
FACILITIES PRINCIPLES OF NEIGHBOURHOOD PLANNING

16. EXAMPLE OF NEIGHBORHOOD UNIT
• One example of such a place is the Port City of Ashdod, established 1956,
which consist of a large port and industrial area to its North and 17
neighborhood units to the South.
• The city has about 250,000 people in it, but instead of utilizing this
congregation of people it is actually made up of 17 villages of 10,000-
20,000 people, each with its own slowly decaying low-level commerce.
• Ashdod is now trying to take one of its arterial roads and turn it into a
real urban street, connecting its disjointed neighborhoods with an
ambitious plan that tackles street network changes, land use changes,
commercial development and public transit. Whether such a change is
feasible is open to debate.

17. CONCLUSION
• Neighborhood planning is quickly
becoming a high priority for the city
planning departments, and even
human service providers.
• Neighborhood planning is effective
and provide inspire those creative
strategies that can increase the
capacity of residents in charting out
their shared future.
• It’s a vision of a better future.
