I like Melbourne City Council’s proposal for higher dwelling densities along tram lines but I think the claim that it would increase sustainability is exaggerated. There’s a whole ‘second half’ missing from this proposal.
The idea, which seems to be largely the brainchild of Council’s Rob Adams, is essentially that multi unit developments of up to 8 storeys should be encouraged along tram routes, leaving the suburban “hinterland” undeveloped (Rob refers to it as a new green wedge). This would reduce the need for fringe development and increase the mode share of public transport.
The major opportunities appear to be on tram routes in the inner suburbs, around 5-10 km from the CBD. While I think the assertion that 4-8 storey buildings can substitute for fringe development is fanciful and is based on a misinterpretation of other research, I accept that the proposal has the potential to increase the supply of dwellings of the type that are sought after by smaller households, especially those without dependents.
The key problem however is that nothing has been proposed to deal with car use by households occupying these new apartments. Without that, it won’t deliver. It just assumes that if households live cheek by jowl with good public transport they will necessarily use it. Read the rest of this entry »
