The capital of New South Wales is currently in Sydney, eastern Sydney, historic Sydney, tourist Sydney, or to speak the language the planners understand, the Harbour City. Parliament meets in a gorgeous building adjacent to the Domain, a large urban park. Government offices are scattered throughout the city and the metro area.
Policy in Sydney has recently engaged around the idea of a 30-minute city, the idea that people can get where they need to go on a daily basis (work, shop, school) in 30 minutes or less by walking, biking, or public transport. (Or that 70% of the people do so, depending on which definition.) This can be achieved through a combination of transport and land use strategies. On the transport side is the question of how fast and how direct the transport network is. On the land use side is the question of where desired activities are located relative to each other. The government of New South Wales is promoting the development of jobs in Western Sydney (and housing in Eastern Sydney) to reduce commuting times and encourage the 30-minute city. This is a noble goal, and the market may move in that direction.
At one extreme we can imagine a completely functionally separated city, where all the homes are on one side of town, and all the jobs are on the other side of town. If the sides are more than 30 minutes apart, there is little that can be done to achieve the goal, though perhaps the connection between the two parts can be made faster or more direct. But since transport networks act to spread out cities physically, it might only induce more suburban development. This functionally separated city is equivalent to the classic monocentric city, with a single dominant downtown surrounded by residential suburbs.
At the other extreme we can imagine a completely functionally integrated city, probably relatively dispersed, where jobs and housing are completely integrated, so there are as many jobs in any suburb as there are workers. There is no guarantee that a worker will be able to find a job next door (or choose it), but the likelihood of finding a job nearby is higher than in the monocentric city
If everything else were equal, from a transport perspective, we would probably prefer an integrated city, as this would place the least strain on the transport network. Moving towards jobs/housing balance is a long held goal, if only weakly operationalized.
But all else is not equal. Employers have an affinity for each other. All the big banks want to be near each other, as do other big companies in various sectors. As does the government. This is what economists call economies of agglomeration.
The government is not just an employer, it is also a major player in real estate markets. It can catalyze development of western Sydney, its Aerotropolis/Parkland City, as it is called in the 2056 Three Cities plans, by moving itself there first.
Cities change with the pre-dominant transport technology. When the capital was established in Sydney in 1788, the dominant technology was animal and human powered, with wind and sails moving ships. Since then, much has changed, and the center of population has migrated inland.
The shape and form of the pedestrian city differs from the rail (trams and trains) city, and differs from the automobile city. Retrofitting trams into the pedestrian city, and especially automobiles into the pedestrian and rail cities broke much earlier urban functionality, while creating new problems, new opportunities, and new designs. Technology played and plays out differently on greenfields, which could be designed to serve a new transport paradigm.
As we approach the transition from the traditional automobile to the autonomous electric and shared vehicle, with all of the ancillary changes, the opportunity for a new city of the future emerges. This technology will invade existing places, which will need to adapt, and new places which can more fully adopt the new technology. But we also need to keep an eye out for the next transition, whatever that may be (flying cars?), so that what we build now is not soon obsolete.
Transport is not the only shaper of cities, other technologies are also critical, from piped water and sewer, electricity, telephony, elevators, and air conditioning historically, to wireless high-speed internet most obviously today, and robotics coming up shortly.
The new capital will need to orient itself around these new technologies, as well as new extensions of well known technologies, like trains and Metros and light rails and bicycles and pedestrians. This is a huge opportunity, and while I won’t suggest a specific design, I will say it should be forward looking as well as reflective of the changes that have come before. Canberra was an opportunity, but by spreading itself out so much, it foreclose the possibility to effectively use slower modes.
A government campus for key departmental headquarters and Parliament at the end of the Mall, a now traditional design for capitals, with the vast majority of government offices scattered throughout the rest of New South Wales, could spark development. Access to the new airport and rail lines will provide connectivity to the rest of the state.
Ancillary businesses, not just those serving lunch to government workers, but those dealing with government on a daily basis, will migrate to deal with their public sector clients and customers. There are many sites on the axis between Parramatta and the Blue Mountains that could serve this purpose.
Sydney’s soon-to-be-abandoned historic Parliament House can have a variety of uses, from appropriately sized conventions to space for a museum. Other government offices in Sydney can be sold off, retrofitted for urban housing, or replaced as warranted. The Sydney CBD is thriving, and will continue to without a few thousand additional government workers. But that could be all the difference in success for a new city for Western Sydney.
In 1908, Australia, then with a population of 4.1 million, decided to relocate to Canberra. Today (2018) New South Wales has a population 7.8 million. As Australia has proven, the political capital need not be the largest city. In the US, most state capitals are not the largest city: St. Paul not Minneapolis, Sacramento not Los Angeles, Albany not New York, Harrisburg not Philadelphia, Springfield not Chicago, Annapolis not Baltimore, and so on to name but a few.
It is time to plan and create a new government precinct, out west, to help spark the development the government seeks. It will bring the government to the people, de-center the government from its locational bubble, and juvenate new places with new ideas.
