Perth risks indefinite urban sprawl with new residential zoning proposals
GUEST OBSERVATION
The declining rate of infill housing in Perth means that a state government backflip on residential design codes would be detrimental to the city’s future development, leading to a restriction in housing choice and further urban sprawl.
Perth’s infill rate, that is residential developments within established suburbs compared to greenfield areas, dropped to 28% in 2012 - down from 32% in the previous year.
The figures, which were recently published by the Western Australian Planning Commission’s (WAPC) Urban Growth Monitor report, fall extraordinarily short of the long-term infill target of 47%.
This target was set as part of the state government’s strategic development plan, Directions 2031 and Beyond, and created to slow Perth’s urban sprawl as the city’s population is expected to balloon substantially in the years ahead.
The fact that the city’s infill rate is far below the long-term target, and more critically, that the rate is actually declining, demonstrates that calls from the WAPC to cut the number of dwellings allowed on certain properties would further undermine Perth’s development strategy.
The WAPC is seeking ministerial approval to effectively reverse a 2010 amendment to residential design codes that significantly increased the number of dwellings allowed on properties zoned R-30 and R-35.
The amendment cleared the way for up to 10 units to be built on 1,000 square metre blocks that are zoned R-30, up from just three units previously.
The move to scrap the amendment is in response to concerns about the impact on predominately single dwelling or grouped dwelling neighbourhoods.
Fast Facts:
32% – The historical net infill housing rate in Perth
47% – The long-term housing infill target rate
59% – Portion of infill developments with one dwelling (2011-2012)
While I agree that medium or high density housing should not be on every street on every suburb, if the WAPC’s calls are granted, then it simply gives the green light for councils to further resist development in established areas, producing and exacerbating problems for the wider community.
If the state government was to backflip on these reforms it would only put further downward pressure on Perth’s development infill rate and make it very difficult to reach the infill target of 47%.
Subsequently, housing choice in established suburbs would be significantly diminished, more people would be forced to live on the urban fringe and housing values would be impacted.
While it is understandable that some might hold concerns about increased traffic in medium and high-density areas, studies have found that building such developments near public transport generally have minimal impact.
Furthermore, if managed and designed properly, a 10 unit development can be smaller in size than three townhouses on one lot.
If Perth is going to accommodate a rapidly growing population, which increasingly wants to live near work and amenities, we simply can’t afford for the urban sprawl to continue indefinitely.
