Urban SprawlAn Overview

What IS urban sprawl?

• Urban Sprawl: Rapid, poorly-planned spread of development from an urban area

into rural areas

• Shorter Definition: Development on rural land at the edge of a city.

Three Types of Sprawl

• Low Density: Single-family homes on large lots

Three Types of Sprawl

• Ribbon: Single family homes on large lots that front an existing road.

• About one lot per 5 acres.

Three Types of Sprawl

• Leap Frog: Neighborhoods outside the city that are more dense. These

developments aren’t directly connected to the rest of the city.

Causes of Sprawl

• Strong Economy

• Population Growth

• Lack of Planning

Urban Sprawl Typically:

• Is low density

• Single use

• Creates heavy car dependency

Benefits of Sprawl :pg. 82 GA

• Cheaper land

• Life-style

• Creates jobs

• More taxpayers

Harmful Effects of Sprawl:

• Loss of farmland

• Increase in taxes

• Loss of wildlife habitat

• Increase in air and water pollution

• Increase in obesity

Versailles and Sprawl

• Size of Versailles has gone from 80 acres in 1793 to 288 acres in 1887 to 2800 acres today.

• Population in 1887 was about 4,500, today it is about 7,500.

• Population has increased 60 percent in 122 years, land use has increased 1,000 percent.

• 3 residents per acre today. About 20 residents per acre in 1887.

What are we doing about it?

• Versailles is working to avoid sprawl

• Created Planning and Zoning Commission in 1954

• This meant that the city controlled how new neighborhoods could be built.

Urban Growth

• Lexington was first city in U.S.(1954) to establish an urban growth boundary.

• This kept the city from sprawling uncontrollably.

“Smart Growth”

• City is walker and mass-transit friendly.

• Includes neighborhood retail and commercial business.

• Preserves open space.

Chapter 5 Questions• 1. Which city has been most effective in

controlling sprawl? Why?• 2. Which has been least effective and why?• 3. Are we likely to see the same living

patterns 50 years from now? If so, why. If not what will be the change?

• 4. Which response to sprawl seems to have been used most in the 3 cities we looked at?

Video Questions pg. 39 ISN1. What are the myths related to a higher quality of

life in the suburbs?Pollution is mostly from cars which abound in suburbia.

There are more traffic accidents and fatalities in suburbia

Clean water sources may be affected by concrete runoff and industrial waste

2. What does sustainable mean? Using resources today but not using them up

3. What is infrastructure? Necessary public facilities needed for growth (water,

gas and telephone lines, streets…)
