The Canadian Dream? Comparing the Densities of Modernist and New Urbanist Suburban Development – A Comparative Case Study of Don Mills, Toronto and Cornell, Markham
Notice bibliographique
Résumé
This report compares the developments of Modernist Don Mills, Toronto and New Urbanist Cornell, Markham across various built form indicators, specifically gross and net residential density, housing mix, land use mix, and street design and circulation. This report assesses the similarities and differences between the developments, which were influenced by their respective suburban planning theories. These built form indicators represent key characteristics which contribute to urban design and morphology. Given that both sites were developed on greenfield, or undeveloped, lands on the urban fringe with a comparable area (835 hectares in Don Mills and 973 hectares in Cornell), the sites are suitable for comparison. Development in Don Mills began in 1953, following the completion of the master plan in 1952. It followed the concepts of Modernism to separate land uses, support residential areas with recreational spaces, employ the Neighbourhood Unit concept, and provide residents with commercial and employment opportunities located in strategic areas. Cornell was first conceived in 1988, with the master plan being completed in 1994 by Duany Plater-Zyberk Co., leading New Urbanist designers. They planned a walkable community based on the New Urbanist principles of mixing housing types, pedestrian scaled streetscapes, and enhancing a sense of community. The Cornell Centre area is the future core area of the project. A secondary plan was released in 2008 which planned for 10,000 residents and 5,000 units in the 240-hectare area. The secondary plan was last revised in 2015 and planned for 18,000 residents in 9,000 new units. This report found that Cornell currently has a gross residential density that is 29% greater than 1965 Don Mills, with the 2015 plan supporting a residential density that will be 76% greater than the original Don Mills development. The current build-out of Cornell has a net residential density that is 71% greater than that of the original Don Mills. This report also found that today’s Cornell has a comparable supply of single detached units compared to 1965 Don Mills, although Don Mills has a significantly higher proportion of high-density units and Cornell has a greater mix of medium density housing. Although the primary land use in both Don Mills and Cornell is residential, 1965 Don Mills had a greater supply and mix of non-residential land uses. Also, both developments utilized a street hierarchy system to reduce the amount of traffic on local roads to improve health, pedestrian safety, and reduce interactions with the neighbourhood interior and heavy traffic. Ultimately, both developments are successful in creating a sense of community for residents while efficiently planning for the allocation of land uses throughout the neighbourhood, despite Don Mills separating land uses and Cornell mixing compatible land uses.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
