Sprawl Investigation
What is sprawl?
Where does it come from and what are the
ramifications?
Why should we care about sprawl?
What problems does it pose and what are the
health risks?
What can we do about sprawl?
What are the alternatives to sprawl and how
can we change our neighborhoods?
Introduction
 Faulty, outdated procedure has economic and
quality of life impacts. Suburban sprawl is a
symptom of this faulty system; the answer is a
return to traditional neighborhood models.

“The deck [is] already stacked against healthy growth by
municipal regulations and engineering conventions.” (101)
 These conclusions are made with the
understanding that:
1. Growth cannot be stopped
2. Profit-motive is not the problem with
development
3. Most issues are inter-related

Defining Sprawl
 Sprawl - To be distributed in an awkward or
uneven manner, esp. as to take up more space
than is necessary.
 Suburban Sprawl – Unchecked, uncoordinated,
haphazard growth outward, esp. resulting from
real estate development on the outskirts of a
city. The spreading of urban development into
areas adjoining the edge of a city.

The Origins of Sprawl
 The popularity of the automobile
 Policies of such programs as the Federal Housing
Administration and the Veterans Administration
 “As long as zoning codes favor low-density development over the
creation of compact communities, developers will not be able to
shake their reputation as land rapists, as they turn farm after
farm into cookie-cutter sprawl.” (100)
 “Even more culpable in this scenario
are those surprisingly powerful advisors
to the development industry, the
market experts.” (101)

Sprawl Planning Decisions:
Creating the Components of Sprawl
Low-density land use
Single-use zoning
Fast food chains, built at sites of future
development
Focus on highway and parking
infrastructure over public spaces
The Components of Sprawl
 Housing subdivisions
 Shopping centers
 Business parks
 Civic institutions
 Roadways

Consequences of Sprawl
Car-dependent communities
Increased fossil fuel reliance and pollution
Traffic congestion and increased traffic
fatalities
Decline in social capital
Class segregation in residential areas
(housing types grouped together, like with
like, McMansion with McMansion)
Increased likelihood of obesity and crime
Suburban Sprawl Unmasked
“Subdivisions can be identified as such by
their contrived names, which tend towards
the romantic – Pheasant Mill Crossing –
and often pay tribute to the natural or
historic resource they have displaced.” (5)
“The contemporary office park is usually
made of boxes in parking lots. Still
imagined as a pastoral workplace isolated
in nature…in practice it is more likely to be
surrounded by highways than by
countryside.” (6)
If it has…
A center
A five-minute walk
A street network
Narrow, versatile streets
Mixed-use zoning
Special building sites (example: areas for
a farmers market)
…then it’s not sprawl

*Activity*
Here’s your neighborhood problem:
traffic congestion
Tools you can use to combat it: design,
policy, or management
 An example: You can choose to solve the problem of crime
by using design – eliminating potential hiding places and
using beautiful and durable materials to display high
standards of civic care; by using policy – having zoning
regulations require entries and windows to face public
spaces; or by using management – having the local cops
get to know residents and develop a relationship with the
community
Problems of Urban Sprawl
Zoning
Isolation and Segregation
Reliance on Cars and the Traffic Problem
Lack of community
Resources inefficiency
Loss of talent/jobs/resources for cities
The Problem with Zoning
Tends to make more efficient mixed land
use illegal.
Separates everything from everything
else.
Promotes auto-travel reliant society.
Creates segregated blocks of space rather
than communities.
Isolation and Segregation
Creates isolated blocks of space rather
than integrated communities
Segregates residents by separating
housing types
Creates a “Move out to move up” lifestyle
Isolation and Segregation
Leads to Fragile Neighborhoods
Enforces sameness and encourages
discrimination and intolerance.

Reliance on Cars and the Traffic Problem
Creates an area entirely dependent on
cars for travel
Because of this dependence, design
focuses on unimpeded auto travel.
While good for cars, this is detrimental to
other forms of travel such as walking or
biking
Pedestrian danger increases as well as
drivers feel safer speeding and driving
carelessly
Reliance on Cars and the Traffic Problem
The Auto-reliant system requires massive
road construction
As more roads are constructed, more
people take advantage of them producing
induced traffic congestion
Traffic congestion motivates construction
of more new roads, which in turn induce
more traffic
The Lack of Community in the Sprawl
The highly segregated car dependent
system requires people to spend much of
their time driving
Instead of interacting meaningfully with
others, people spend most of their time
competing with them for road access
The Lack of Community in the Sprawl
 Remaining time not spent driving is spent
confined in the cookie cutter housing cluster
 With nothing to differentiate any given suburban
sprawl area from another, a sense of unique
place fails to develop
 Without a sense of place or opportunities to
meaningfully interact with each other,
communities fail to form and people are left in a
void
Resource Inefficiency
New Suburban sprawl areas require
massive amounts of resource expenditure
to create.
The isolated and auto-reliant setup waste
huge amounts of time and energy in transit
Huge amounts of resources are also
expended on maintaining and expanding
roadways
What the Cities Lose
Suburbs are perceived as better places to
live, thus those who can leave the cities do
so
Businesses leave along with the people
The poor who are unable to leave are left
behind in an economically weakening area
This leaves cities with a shrinking resource
base with which to try and deal with
increasing problems
What the Cities Lose
This in turn further motivates people to
leave, which further worsens the situation,
creating a vicious cycle

The Traditional Neighborhood
Development (TND) Model
Model Exceptions:
 Old communities
 No population growth
 Where city infill is
possible
 When it will promote:
Unnecessary automobile
use
Unnecessary greenfield
development
The Duany, Plater-Zyberk, and Speck
Plan
1. Mixed-use
development
2. Connectivity
3. Discipline of the
neighborhood
4. Making transit
work

Mixed-Use Development
1. Residence
2. Shopping
center
3. Workplace
4. Civic buildings
Connectivity
Neighborhoods
should meet
Avoid collector
roads
Highways should
skirt towns
Discipline of the Neighborhood
 Pedestrian Shed
 “the five minute walk”
 Use natural features
 Zone buildings by size
 “Pocket parks”
 Culture to nature
 Urban to rural

Making Transit Work
1. Frequent and

2. Direct, logical

3. Safe and

The Parking
The Style
The Streets
 Residential street
 Yield streets
Travel lanes 10 ft.
Parking lanes 7 ft.
Westhaven
Katrina Cottage
The Buildings
 Houses close to
street
 Encourage sociability
 Retail without
setbacks
 Taller is better
Parking and Style
 Mixed-use parking
 “If every building
were to croon at
once, nothing could
be discerned from
the cacophony”
(211).
*Activity* ~ let’s try it again
 Here’s your neighborhood problem:
traffic congestion
 Tools you can use to combat it: design, policy, or
management. Use the knowledge we’ve given
you; try utilizing a different tool this time.
 An example: You can choose to combat the problem of
crime by using design – eliminating potential hiding places
and using beautiful and durable materials to display high
standards of civic care; by using policy – having zoning
regulations require entries and windows to face public
spaces; or by using management – having the local cops
get to know residents and develop a relationship with the
community
Government
 MUNICIPAL AND
COUNTY GOV
Agenda setting
Rewrite regulations
TND ordinance
Be proactive
Think Globally
Public participation
Set an example
 REGIONAL GOV
Create strong regional
governments
Create detailed plans
Create physical plans
Government cont.
 STATE GOV
“Tough love” programs
Affordable housing
Educational goals
 FEDERAL GOV
Public transportation
Tax policies
Federal incentives
Equal education
resource distribution
Coordinate policies
Public support for
Private initiatives
Conclusion
 A faulty, misguided system gives birth to suburban
sprawl, which needs to be replaced by healthy,
traditional neighborhood models.

Discussion:
1. Of your solutions to the traffic congestion
problem, which would be most effective?
Why?
2. How realistic is the TND model?
3. How do the authors’ professions affect
your opinion of their solution?
