Introduction: The Ottawa Greenbelt was proposed by French planner Jacques Gréber in 1950 as part of the master plan for Ottawa. It is 203.5 km2, being owned by the National Capital Commision, government departments and private interests. It was intended to be a rural landmark, limit sub-urban sprawl, accomodate federal and research instuitions, and preserve and provide natural areas. The Greenbelt`s external shape is not so significant, rather it is the pockets of urban space within the greenbelt, located near Kanata and Orleans, which we believe to be catalytic in the growth of the two sub-urban areas.

The program of the greenbelt includes natural areas, forestry, instituitional, agricultural, recreational, commercial and residential. Its diversified program makes the Ottawa Greenbelt different from other greenbelts as it allows deliberate urban development to occur as part of its planning. However with all it`s multifunctionality, we question if this af-fects it`s intergrity as a greenbelt and whether or not this is causing positive effects.

In this case study we will look at the multifunctional composition of the Ottawa greenbelt and the idea of how this is causal to accelerated sub-urban growth external to the green-belt.

NATURAL AREASCore natural areas are connected by a long corridor. Besides hiking and admiring preserved nature, you can find golf courses, soccer fields or tenniscenters in the Greenbelt.

AGRICULTURAL AREASA key idea of the greenbelt is to protect agricultural land in order to provide local produce. The most common crops are corn, soybeans and cereals.

DEVELOPED AREASThe Ottawa Greenbelt has several areas of land that includes residential, commercial, recreational and instituitional developments to occur.

INFRASTRUCTUREInfrastructure within the greenbelt causes disturbances in between rural and natural spaces.

INNER OTTAWA AREA

This diagram is to show the failure to stopsuburban sprawl. Areas such as Kanata, South Nepean and Orleans are now growing rapidly since the establishment of the greenbelt. The separation of neighboring suburban areas creates many commuters that travel from thierrespective areas to the downtown Ottawa area, causing high infrastructure costs and long commute times.

BIG circle = BIG population

MORE rings = MORE density

By 2020, two thirds of all population will be accommodated behind the Greenbelt.There are three proposals of the future development:

1. The City of Ottawa has proposed that a quarter of the Greenbelt should be developed. Development would take place along major roads within the Greenbelt.

2. Development can occur within the Greenbelt as most of the land is still under or un-developed.

3. Expansion of the outer cities can continue.
