Is new urbanism old?

The 10 principles of New Urbanism are:

1. Walkability
2. Connectivity
3. Mixed use and diversity
4. Mixed housing
5. Quality architecture and urban design
6. Traditional neighbourhood structure
7. Increased density
8. Smart transportation
9. Sustainability
10. Quality of life

According the wikipedia entry “This new system of development, with its rigorous separation of uses, became known as “conventional suburban development” or pejoratively as urban sprawl, arose after World War II. The majority of U.S. citizens now live in suburban communities built in the last fifty years, and automobile use per capita has soared.

Although New Urbanism as an organized movement would only arise later, a number of activists and thinkers soon began to criticize the modernist planning techniques being put into practice. Social philosopher and historian Lewis Mumford criticized the “anti-urban” development of post-war America. The Death and Life of Great American Cities, written by Jane Jacobs in the early 1960s, called for planners to reconsider the single-use housing projects, large car-dependent thoroughfares, and segregated commercial centers that had become the “norm.”

Rooted in these early dissenters, New Urbanism emerged in the 1970s and 80s with the urban visions and theoretical models for the reconstruction of the “European” city proposed by architect Leon Krier, and the “pattern language” theories of Christopher Alexander.”

New urbanism was fundamentally a social planning movement although it has morphed more recently to include at least a minimalist environmental agenda. Wendy Morris says new urbanism was “….Initially A Reaction to Sprawl…..Now A Basis for Sustainable Urban Growth/Smart Growth…….and a response to Climate Change and Peak Oil…and a Basis for Addressing Physical Health and
Social Well-being.”

Can the old theory of New Urbanism be adapted to adequately address new environmental concerns?

Panda pandemonium

China’s number one mascot the giant panda (ailuropoda melanoleuca) are only found in the bamboo forests of south western China. “They occupy 6 small forest fragments in the provinces of Sichuan, Gansu and Shaanxi. (5,400 square miles).”

The panda is well travelled in popular culture, as well as being a local hero. With the recent release of Kung Fu Panda, the panda Po looks set to win over another generation of children to panda love.

Habitat fragmentation (by roads and railroads) and destruction and poaching (for their pelts) are still major threats to the Giant Panda, even though poachers and smugglers have received death penalties or long prison terms. Pandas are often injured in traps and snares set for other animals.

Emerging threats to the panda populations are mining, hydropower and tourism. A giant panda may consume 26-83 pounds of bamboo a day to meet its energy requirements.

What makes travel a great experience?

Design schools are starting to tackle questions of urban scale city design in their masters programs. The key to future transit systems is to make that form of travel the best it can possibly be. Ask, what would make people choose this form of transport over other alternatives if they had many equally accessible and affordable options? Why might they want to travel this way? What would be unique, good or special about the experience?

The beginning or the end of the car?

Is peak oil, sustainability and climate change the beginning or the end of the car as we know it? With the advent of modernism carparks became first part of a highrise building to be constructed and were considered as part of the foundation system. There are a number of concerns with parking in urban areas. Will pollution and noise issues be meet by electric cars? Will innovative greened multistacking carparking arrangements be proposed for multi-density dwellings? How will congestion be addressed?

How will car supply and demand issues be thought about? Should urban residences be carfree with the possibility of outer-urban garaging accessible beyond the urban core area? Should urban work and commuting also be limited to the periphery of the inner-core? If so, who should be able to access this inner centre by car? Why?

Will eco-traffic engineers be engaged to design flow throughs and do capacity modelling for all new development sites so that designers can innovate and demonstrate best practice? Who will dream of the transit and traffic organisational schemas of our new cities?

More questions than answers!

Re: cycling It is Cost Effective

What is needed to induce the die-hard city commuters to leave behind their cars and adopt cycling as a mode of transport? Should the cost of using the car in central city areas be so cost prohibitive that only the those willing to part with large sums for the privilege persist? Or should urban designer adopt a range of innovative measures to entice inner city commuters to adopt what is afterall a healthier lifestyle alternative?

The McDonalds Cycle Centre in Chicago’s Millenium Park is leading the way in rethinking what it means to cycle and the sort of facilities which may transform the way commuting and recreational cycling is viewed. Philip Modest Schamberlan and + Anton Fromm’s Bicycle Hotel intends to entice the cyclist into the mountains in pursuit of a recreational touring lifestyle by providing an intriguing Fractal experience perched above Lake Garda.

Social and Sustainable Streets

Model Streetscape


Perhaps the designers of this streetscape had already absorbed Robert’s message. Not only the shade trees (Cinnamomum camphora), but lots of heat-island reducing planters too. Not so many parked cars as in Bermondsey, but of course loads of bicycles and mopeds. The great majority of the mopeds in the picture are electric. So far, so sustainable. But, this is also a social streetscape. Behind the arcade on the left are the lunchtime restaurants, the vegetables are prepared on the pavement under the arcade and the customers enjoy a cigarette after their meal on the benches and raised walls in the balmy, late autumn sun. The large, evergreen shrubs – Osmanthus fragrens – fill the air with their light scent. Residents dry their washing on the clothes racks outside their apartment windows without the use of machines. One of many such streets in the Pudong New District of Shanghai, all not much older than 15-20 years.
