“..the revolutionary rhetoric of Modernism passed a death sentence on the street.”– Stephen Marshall, Streets and Patterns
I lobbed a few easy questions at the end of my last post:
“What has happened to Great North Road that makes is so low scoring in this analysis and so seemingly low value on the ground?”
One correct answer, as many suggested, is that Great North Road is affected by motorway severance thus leading to reduced network connectivity. The other answer, one that is not depicted in the simple network analysis, is that the actual accessibility conditions on the ground seriously limit local trips and these two structural conditions work in tandem to yield a disurban environment. Below is a look at Great North Road, pre-motorway. It has a fingerprint very similar to Ponsonby Road or Queen Street where buildings are clustered at intersections along the edge of the street where the real estate value was located.
So while Jane Jacobs argues for the necessity of short blocks, if not so much for their physical properties (which are also important- see Portland’s smalls blocks designed to increase real estate value by providing more corners), but mostly since they allow a variety of movement modes and choices, something not available any more on Great North Road nor along most other corridors in Auckland.
The discussion from the last post inspired me to dig up some of my previous work examining the urban form changes in Auckland’s first ring suburbs.
In Auckland, like virtually all large western cities, there was a concerted effort, sometimes explicit, to disperse the intensity the city centre to the suburbs. This was facilitated by the motorway system and just about every other transportation investment and policy decision. Below are the results of that policy on the ground throughout Eden Terrace. In addition to the motorway, the severance of the ancillary road system like the Dominion Rd Flyover also contributed to radically transform and degrade local neighbourhoods.
Here is a different view of the outcome of this ‘disurban’ experiment as calculated by surface parking and asphalt- a good indicator of anti-urban environments.
So in addition to the severance or barrier environment of the motorway, the local street conditions of Great North Road and Dominion Road Extension have helped to atomise the value of the city (accessibility, proximity, and convenience) across the landscape. In the next few posts I’ll be taking a closer look at some of these streets from the ground level.
