Andrew Blum recently wrote,

I think we’re not too far off from recognizing that it’s a moral imperative to add density to any place with a transit stop,” believes Christopher Leinberger, a fellow at the Brookings Institution—displaying plenty of the modernist brio and contempt for the souls of cities that Jacobs fought. But I’m tending to agree. We are wedging ourselves between a rock and a hard place: between the pleasures of medium-density living (Greenwich Village, Park Slope, Toronto’s Annex) and the ecological necessity of even more density.

And in “Hamilton: the Electric City“Richard Gilbert said,

Because of transport’s key role in energy use, particularly use of fossil fuels, a specific principle concerning the relation between land use and transport may be helpful. Historically, transport planning has served land-use planning. Current practice is to integrate them so that both occur together. For an energy-constrained world, it may be expedient to plan transport first and then arrange land uses to serve the transport activity. A transport objective could be, for example, that half of all commuting occurs on foot or by bicycle. Land uses would then be proposed that would facilitate attainment of this objective.

Which leaves me wondering if “sustainability” has been sufficiently infused into community-based planning. While the Campaign’s platform and policies were prescient, with references to sustainability like the following:

In meeting its infrastructure needs, the City must be guided by principles of sustainability by giving priority to strategies that maximize utilization of existing infrastructures such as retrofits of sanitation department marine transfer stations and re-powering of power plants. The City must work with community groups to identify those capital infrastructure investments that reduce local air emissions. (Principle 5)

perhaps, in light of recent science and the concerns that have arisen around the sustainability movement, we should revisit the platform for a “sustainability once-over.”
