Sprawl
![Page 24: Progress, not Perfection](https://reader035.vdocument.in/reader035/viewer/2022070422/5681649b550346895dd67ae0/html5/thumbnails/24.jpg)
• Economically–Forces the government
to provide new infrastructure for a dispersed population
–FACT: the average American family spends 14%-18% of its total budget on transportation
Effects of Sprawl
![Page 25: Progress, not Perfection](https://reader035.vdocument.in/reader035/viewer/2022070422/5681649b550346895dd67ae0/html5/thumbnails/25.jpg)
Possible Solution
• Economically– Compact development
arrange new homes together so services can be provided efficiently
– Compact development provides people with the choices, instead of driving, decreasing the amount of money spent on gas. City Hall East

Effects of Sprawl• Environmentally
– Longer distance driving = increase in air pollution• FACT: air pollutants from
cars are responsible for 20,000 – 40,000 annual cases of chronic respiratory illnesses.
• FACT: The World Health Organization estimates that 4.6 million people die each year from causes directly attributable to air pollution
![Page 27: Progress, not Perfection](https://reader035.vdocument.in/reader035/viewer/2022070422/5681649b550346895dd67ae0/html5/thumbnails/27.jpg)
Possible Solution
• Environmentally– Compact
developments provide opportunities to walk, bike, or take public transit, therefore reducing air pollution Wade Green

Effects of Sprawl• Socially
– Traffic congestion takes away time from everyday life• FACT: the average
American driver spends 443 hours per year behind the wheel.
– An increase in driving means and increase in auto fatality rates
– Absence of pedestrian friendly routes decreases the opportunity for exercise
