Spreading out development creates water distribution problems and can lead to water
overconsumption. A typical low -density or suburban community uses more water than a
high-density city community. Landscaping is the primary culprit for this excessive use of water.
According to the EPA, 30 percent of the water used daily in the United States is devoted to
outdoor use. Loss of Wildlife Habitat The San Francisco Bay Area, with over 400,000 acres of
natural landscape, is one of the nation’s six hotspots for biological diversity, according to the
Center for Biological Diversity. The region has a wide variety of plant and animal species;
unfortunately, 90 of them, including the California tiger salamander, are lis ted as endangered or
threatened. Rapid development can negatively affect wildlife by tearing down, clearing, or
building over its habitat, potentially threatening survival. This is not only a problem in the
San Francisco Bay Area; it’s a problem in all of America. Increased Racial and Economic
Disparity When residents relocate outside of a city’s core, they take their tax dollars with them.
Often, it’s the city’s poorest residents that are left behind. This creates economic disparity
and stratification based upon location. It also creates funding problems for the core, which
directly affects the money available for education, crime prevention, and maintenance and
upkeep. Urban sprawl can also lead to economic “white flight.” According to “Urban Sprawl:
A Reference Guide,” urban sprawl leads to racial segregation as minorities are often left behind in
the poorest parts of a region. This problem may not be as widespread as it has been in the past,
but it's present nonetheless. Increased Risk of Obesity People living in suburban areas are more
likely to be obese than people living in urban areas, according to the Ontario College of Family
Physicians and the American Planning Association. Both studies show that people living in
suburban areas tend to rely on their vehicles more often--even for short trips--instead of walking
or cycling. This lower level of activity increases the risk of obesity, which can lead to other health
problems such as heart disease, high-blood pressure and diabetes. 19 | P a g e High Speed Rail Negative BDL No Solvency – Urban Sprawl Turn – Link Extension
[____] [____] Instead of increasing centralization, high-speed rails increase emigration out of the city
Jason Kambitsis, city planner and contributing editor for Wired.com, 2010
(Wired, “High-Speed Rail as a Conduit of Sprawl”, http://www.wired.com/autopia/2010/03/high-speedrail-and-sprawl/)
It’s fast, it’s efficient and it is the future of transportation, but will high -speed rail cause sprawl?
Yes, it could, warn some urban planners. Despite the promise of creating more densely
populated urban centers, high-speed rail could do quite the opposite by making it easier
for people to live far from urban centers. Let’s use California as an example, since high-speed
rail has made the most progress there. The Golden State, long known as a trendsetter for
transportation and environmental policy, has received more than...
