Growing populations have a tendency to
sprawl across the land. Sprawl is characterized by the loss of
natural environment as people spread homes and businesses over
unnecessarily large expanses of land. Anyone who lives in the Greater
Toronto Area recognizes the associated problems: traffic congestion, pollution, vast
acres of buildings without farms or forest for relief, etc.
There was a nice series a while back in the Globe and Mail by Wallace
Immen, Sprawling city at a crossroads
(Sept 25, 2000). If we were at a crossroads in 2000, we were not able to
choose the path less traveled. Quite the contrary, more and more people
are traveling the roads around Toronto and more will continue to come.
The Ministry of Municipal Housing and Affairs oversees the
Land
Use Planning. The Ontario
Planning Act (1990) was established to "promote sustainable economic development in a healthy natural environment"
and it requires each region to create plans for regional development.
Halton's Regional Plan (1995)
has recently undergone revision as part of a required review process,
culminating in Amendment
25 to the Official Plan. The regional plan sets out guidelines for
greater urbanization of Halton, while attempting to preserve agricultural
lands and some natural spaces. The region has little ability to limit
population influx as that is controlled by provincial policy. "This year, the
[provincial] government will release a Growth Management Plan for the Golden Horseshoe that will articulate a long-term strategic vision and tools for how the Golden Horseshoe and surrounding areas should grow over the next 30 years."
That plan includes the addition of a projected 4 million people to the
region.
Oakville Councillors Elgar and Sandelowsky
are strong proponents of environmental protection and are working hard to reduce
the impact of sprawl. In addition, many organizations are working in
Halton to halt sprawl: Oakvillegreen Conservation Association
Oakvillegreen Coalition on the Niagara Escarpment
Halton/North Peel Naturalist Club
Protecting Escarpment Rural Land
(PERL). Offer these organizations your support.

"The Canadian portion of the Carolinian Life Zone has been described as the most ecologically-degraded part of the Great Lakes basin.8 Forest cover has been reduced from 80% to 11%, and wetlands from 28% to 5% of the area. Only 0.07% of southern Ontario is now in old growth condition (over 120 years in
age). Nearly all of the remaining “natural” cover in the Carolinian Zone has been logged, irrigated, cleared, polluted or otherwise disturbed by human activities at one time or another over the past few centuries. Because the most intact natural areas have persisted where feasibility of agricultural and urban development is poor, the remnant vegetation proportions differ significantly from pre-European settlement
conditions."

- Although the Greenbelt
Protection Plan is an essential beginning, the protected region should
be enlarged to make urban sprawl smaller. Highways should not fragment
the Greenbelt (see Ontario
Greenbelt Alliance website).
- Halton region does not appear to recognize the significance
of canopy protection and creation. Central Toronto has an average of 20-35%
tree coverage (Toronto's
environmental plan, 2000), compared to Oakville's 13.5% (
Comments on draft Halton Tree Bylaw) and the overall Halton
region's 16.9% coverage (Larson et al. 1999, The Woodland Heritage of Southern
Ontario) The Ministry of the Environment (1998)
recommends watersheds should exceed 30%. The American
Foresters recommend "communities should strive
for an overall coverage of 40%" for biodiversity protection and
human health, (Urban
Sprawl Information, see also How Much Habitat is Enough?
Environment Canada) Canopy coverage prevents stormwater runoff,
improves air quality, provides summer energy savings, carbon storage
and avoidance, etc., while helping to limit sprawl.
| Between 1990 and 2002, residential energy use increased by 8.6 percent, or 110 petajoules (from 1289 to 1399 petajoules). From 1990 to 2002, GHG emissions from the residential sector increased by 8.4 percent. GHG intensity changed little because fuel switching towards less GHG-intensive fuels offset an increase in the GHG intensity of electricity production over the period.
[One factor influencing the increase in residential energy use
is] the increase in the number of households and the size of dwellings (the principal measures of residential activity) increased energy use by 23.4 percent (302
petajoules)
(Improving Energy Performance in Canada
– Report to Parliament Under the Energy Efficiency Act - 2003-2004 |
- Supersizing of homes should be limited by upholding percentage lot
coverage in existing communities (e.g. requiring tree coverage where
appropriate) and by taxing excessive energy consumption in homes
designed for few occupants.
- Currently R2000 is a voluntary standard for constructing energy
efficient homes. High efficiency furnaces, energy efficient windows,
etc, should be encouraged in all new constructions.
What are the costs of Sprawl?
- The St. Louis SuburbanSprawl
page outlines some of these costs:
- Suburbs
- "The development (over development) of the
suburbs has had many ill effects on the suburbanites themselves.
Proliferation of housing developments, strip malls, and office
parks robs just as much "nature" from a suburb as
skyscrapers and apartment buildings do from the city. The
"green leafy" suburbs to which many families have
moved turned out to be just as gray as the cities they left
behind. Moreover, because suburban dwellers (unlike their urban
counterparts) cannot walk to most public accommodations
(schools, stores, etc.) suburban traffic can often be worse than
traffic in the city. Furthermore, time spent commuting to work,
driving children to activities, and caring for large properties
often robs many suburbanites of leisure time. Finally the
placement of houses set back on large lots and the dependence of
suburbanites on an automobile prevents the day-to-day
interaction among neighbors, thus denying the residents a sense
of community that is seen in the old-time neighborhoods in the
city."
- Cities
- "Suburban sprawl has also had negative
effects on city dwellers. Because there are far fewer rental
units in the suburbs than in the city, and because suburban
survival necessitates the ownership of a car, the poor are often
denied the opportunity to move into the suburbs (they can only
afford to remain in the city). Therefore, the average income
(and thus the tax base) of the city decreases. Schools and city
services suffer. Buildings remain vacant and decay. The flight
of businesses to the suburbs take their jobs out of reach of the
poor who often cannot afford a car needed to commute to the new
location."
- Economy
- "The low density housing in the suburbs
drains the infrastructure. Roads and utilities must be stretched
much further to serve the same number of people than they do in
the city."
From July 23 LA Times: "Drawing a connection between urban sprawl and high transportation
costs, a study released Tuesday suggests that families living in spread-out
metropolitan areas with weak public transit networks spend more of their
household budgets on transportation than people in denser regions.
Across the nation, such costs now eat up a greater share of families'
incomes than ever, taking nearly 20 cents of every dollar earned by the
average household and 40 cents of every dollar earned by the poor, according
to the study, which analyzed 28 metropolitan areas nationwide." (Caitlin
Liu, "Sprawl
Tied to Higher Transportation Costs", L.A. Times, July 23, 2003).
- Environment
- "It is clear that the slash and burn
philosophy of suburban sprawl is detrimental to the environment.
Used areas of the city are left vacant as the pristine
countryside is devoured and subdivided. ... The suburban
reliance on the automobile causes air pollution and depletes
natural resources. The chemical treatment of so many 1/2 acre
"pieces of green" pollute the environment."
- Health
- The Center for Disease Control reports adverse
health affects due to urban sprawl. Such things as children's
asthma, pedestrian fatalities, high blood pressure and stress
are linked to poor urban planning. See their report entitled Sprawl
Watch.
