Facts - Driven to Action - A Citizen’s Toolkit)
GETTING THE FACTS: THE COST
OF SPRAWL
Sprawl doesn’t
pay. In fact, sprawl hurts national and
local economies. It costs more to accommodate growth by building new roads,
electrical lines, sewer and water infrastructure for brand new subdivisions,
office parks and shopping centres, than by integrating people into existing
areas. There are further costs associated with impacts on the environment and
on public health. The rise in cost is directly related to the distance traveled
to city or town centres. More economic benefits of growth are realized if new
residents and jobs are directed to existing developed areas.
In 20 years, Winnipeg’s
urban boundary quadrupled even though its population only doubled. According to
Statistics Canada, the City of Calgary exceeds 700 sq. kms - close to the size
of New York City’s 5 boroughs. But Calgary is home to only 1/10 of the number
of people as New York.
COST OF SPRAWL IN DOLLARS
Sprawl is supposed to be
paid for by money raised from development charges and from property taxes
collected from new residents. But this revenue falls far short of the costs.
Homeowners
• It costs more to live in
sprawl developments.
• The price of a new home in
a sprawling development might be cheaper but home resale values are less and
property taxes are more likely to rise in the future.
• Car ownership and
maintenance costs increase as families move farther from the downtown core. In
2001, Canadians spent 13% of their household income on cars, 19% on shelter and
11% on food. Residents of Houston, Texas (plagued by sprawl) spent 22% of their
family income on cars, which surpassed housing costs at 16% of income.
COST OF SPRAWL ON THE
ENVIRONMENT
Climate Change & Energy
• About 70% of greenhouse
gas (GHG) emissions from transportation are from cars and trucks and 2/3 are
generated within urban areas. The more urban areas extend outward the more GHG (Greenhouse Gas) emissions grow, making it difficult for Canada to meet its Kyoto pledge.
• Sprawl’s dominant reliance
on cars strains Canada’s energy supply, and adds to pressures to find new
supplies.
New tar sands oil extraction
in Alberta produces 125 kg of GHG emissions for each barrel of oil produced,
far more polluting than traditional energy sources.
Lands, Wildlife & Water
Quality
• Sprawl consumes greenspace
and forests.
•Woodlands and wetlands are
sacrificed to sprawl, depriving wildlife of habitat and destroying native flora
and fauna.
• Sprawl threatens rare and
endangered species and contributes to exotic species invasion. Creating small
isolated forest patches can disrupt pollination, seed dispersal, wildlife
migration and breeding.
•Water quality and quantity
declines with sprawl and the removal of forests by creating more pollutants and
eliminating natural filters.
• Sprawl reduces rainwater
absorption, interfering with the recharge of groundwater
Cost of Sprawl on Public
Health
• Cars are a major source of
air pollution. Over 16,000 Canadians die prematurely from air pollution each
year. Smog and particulate matter also cause respiratory diseases and
impair lung function
• Sprawl is linked to
increases in obesity in Canada, due to a lack of space or opportunity for
physical activity. Obesity can lead to heart disease, hypertension,
stroke, some cancers and premature death.
• Sprawling subdivisions
place time burdens on families with longer commutes and children who cannot
travel independently. Families that need to downsize their homes often have to
leave their neighbourhood and friends. Elderly residents who can no longer
drive are isolated.
• The loss of nearby
farmland reduces the availability of fresh fruits and vegetables.
• A recent study, in the
medical journal Public Health Reports, showed that people living in walk-able
neighbourhoods were more
likely to know their neighbours, participate politically, trust others, and
be socially engaged.
• The Ontario Medical
Association says air pollution costs Ontario more than $1 billion a year in
hospital admissions, emergency room visits and absenteeism from jobs.
No New Roads
Establish Moratoriums on
Highway
and New Road Construction
Expanding local
transportation choices is not enough. Every new highway, expressway or
municipal thoroughfare encourages sprawl. Limited transportation dollars are
better spent on public transit, bikeways and pedestrian routes. Congestion is
alleviated when more people ride transit, not by building new roads.
Build Communities Under A
New Standard
Establish Local Alternative
Develop Standards
Alternative Development
Standards (ADS) offer a new set of development regulations to help build
communities that: are compact, affordable, competitive; support public transit;
and are environmentally sensitive and socially responsible. Applying these
standards in your community increases opportunities for growth within cities,
eliminating the need for consumption of new land and creation of
more sprawl. Based on the
concept of creating mixed-use communities, residents can live, work, shop and
play all in the same neighborhood. Using ADS can reduce housing costs by 25-40%
and reduces per-person production of greenhouse gases by 30-50%.
