State of Australian Cities 2013

State of Australian Cities cover

The fourth State of Australian Cities report was released this week and includes interactive web-based maps and the second tranche of  Australian Bureau of Statistics’ 2011 Census population and housing data.

The report’s main focus is how the change in Australia’s industrial structure (described in the 2012 report) is affecting its major cities and what this may mean for productivity and equity.

Interesting facts include:

  • Australia has one of the highest population growth rates in the OECD.
  • Aside from city states like Singapore and Monaco, Australia is the most urbanised nation on earth.
  • An increasing number of people are living further away from city centres in major cities while higher-skill, higher-paying jobs, are becoming concentrated in central areas.
  • Australian cities tend to have higher private car use than public transport use when compared with overseas cities.
  • Since 2008, residential energy use has accounted for 12 per cent of Australia’s total energy consumption.
  • Energy demand for space heating and cooling is projected to increase in the coming decades. Factors influencing increased demand include houses with the largest average floor areas in the world, the decreasing occupancy rate of dwellings and the increased use of whole-house heating and cooling systems.

  • Nearly 40 per cent of total national energy use is expended in moving people and freight. The transport sector uses 73 per cent of Australia’s total liquid fuel, with over half of that being used by road transport.

  • The transport sector also contributes the largest proportion of average household carbon dioxide (CO2) emissions at almost 42 per cent. Light passenger vehicle use alone accounts for 35 per cent of Australia’s average household emissions, by far the largest overall component of the transport sector’s emissions.

  •  Rates of walking and cycling fell throughout the 1990s before recovering in the first decade of the century. The proportion of journeys to work made by bicycle is now the highest it has been in 40 years.

How to increase densities without losing the neighbourhood

Metropolitan plans in Australia over the last decade have increasingly advocated for higher densities to accommodate growing urban populations. Higher housing densities are being supported for a whole range of reasons including to protect precious agricultural and bush land, to reduce sprawl and associated negative impacts such as increased travel times and distances.

However local planning controls, financing and development have not always been able to change as quickly to deliver on these targets, nor have communities embraced or agreed with such plans.

As planners, designers and developers struggle with how to implement alternatives on the ground, particularly in the face of community opposition it is interesting to discover more about innovative options that are out there. Not the ones that deliver more of the same – single detached, double garaged McMansions, or alternatively high rise apartments – but rather the middle ground, developments that not only increase densities, but also bring the benefits of density to the occupants without the perceived negative impacts.

Pocket Neighbourhoods

Pocket Neighbourhoods by Ross Chapin (2011) offers some interesting alternatives and includes examples of compact housing developments that provide a sense of community and a link between neighbours through shared common spaces.

Increasing housing choice

One of the featured case studies is that of Kirkland, Washington (East of Seattle, U.S.A.). Kirkland city planners faced the challenge of how to increase housing supply and choice for a growing population while limiting sprawl and decided to invite developers and architects to write their own rules. There were few guidelines, but the main one was a limitation on the size and type of homes, thereby allowing more houses than would normally be permitted in a standard subdivision.

Creating new planning codes

The restrictions were that the city would accept only five  applications and had no obligation to approve any of them. The ones that received approval and were constructed would be thoroughly evaluated and considered as the basis for a new planning code.

As a result of this, Danielson Grove was developed (see Pocket Neighbourhoods pages 74-77 for more details, picture below) and was one of only two projects accepted by the City of Kirkland under its Innovative Housing Demonstration Ordinance.

After the two projects were completed the city’s planning department followed up with an extensive evaluation to decide whether the regulations demonstrated should be permanently adopted citywide. The study found that they provided a welcome alternative to the large homes being built and integrated well with the surrounding community.

Benefits of Pocket Neighbourhoods

Due to the homes being noticeably smaller than the average house being built at this time, there was not a perception of higher density, nor was there a noticeable increase in traffic. As a result, most of the standards proposed in these sample projects were adopted in a new housing zone code.

Influential Australians

The book also makes mention of two Aussies influential in this area, Paul Downton, co-founder of Urban Ecology Australia and Director of Ecopolis Architects responsible for the design of Christie Walk in Adelaide and David Engwicht and his concept of “mental speed bumps”, activities that naturally slow traffic down.
