Although both the concepts of liveability and sustainable development can be difficult to define, both are crucial to the well-being of communities, that is, their resilience, their stability, and their future. These concepts, therefore, need to be defined, and continually refined, by each community and embedded in a dynamic planning process. There is clearly an accepted general conceptual definition in the planning and academic milieu, but it is not a straightforward concept to communicate. Everybody would agree that ‘liveability’ is a good thing, but are unlikely to agree to what that means. For some it would be choice, for others new urbanism style development, for others perhaps urban forms that would be the antithesis of sustainable development – large house, large lots, large cars. Similar problems are faced with other, certainly positive, but nebulous concepts such as quality of life. For the delivery of sustainable infrastructure, it is the components of liveable communities that support sustainable development that should be encouraged, other components of ‘liveability’ such as those espoused by the City Vancouver and the Town of Okotoks, will develop as the result of public participation in the planning process. Tthis means that liveability should be seen as a policy of participation and inclusive planning rather than any preset physical infrastructure goals.
If this policy is implemented on a neighbourhood scale, it will also ensure a development of local distinctiveness, a sense of place and community identity. These are important components of sustainable communities (de Figueiredo, 1998).
Many case studies, including this one, show that real success in delivering liveability and sustainable development requires both grassroots activism and political leadership. What then should be proposed for those communities where neither or only one of these is present? Perhaps liveability is a suitably all encompassing term that can win the necessary support for a more progressive urban policy?
