Sprawl


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.

Things you can do:

"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.

"WHAT IS ENVIRONMENTAL JUSTICE?
There are three fundamental environmental justice principles:
  • To avoid, minimize, or mitigate disproportionately high and adverse human health and environmental effects, including social and economic effects, on minority populations and low-income populations.
  • To ensure the full and fair participation by all potentially affected communities in the transportation decision-making process.
  • To prevent the denial of, reduction in, or significant delay in the receipt of benefits by minority and low-income populations.
