On February 21, when China’s State Council released a new set of urban development guidelines, it backtracked on many of the conventions that have defined the past two decades of rampant urbanisation.

These new guidelines aim to produce a framework which will revamp and revitalise China’s cities to create urban areas that have improved navigability, tighter-knit communities, better access to commercial and public areas, and that are less resource intensive.

These new directives were taken from the recommendations derived from a rare meeting of the Central Urban Work Conference this past December – the last time it met was in 1978 – and come down from the top echelons of power in the country. They are, to put it bluntly, an enormous milestone that should have a drastic impact on how China’s cities develop into the future.

Over the past couple of decades, China has been undergoing an unprecedented urbanisation boom. Cities across the country have been building hundreds of completely new sub-cities, districts, and towns as China’s urban population jumped from under 20 per cent of its total population in 1978 to 57 per cent today.

The breakneck speed of urbanisation during this era often outpaced quality planning, and China gradually became a land of single-use, car-dependent, Soviet-style superblocks. This has resulted in a uniform urban landscape across the country – “a thousand cities with the same face,” as it is often put. Environmentally speaking, these water-heavy, land-intensive, and car-dependent sprawling new urban areas were horrendous. What’s more, over a million villages, myriad historic areas, ancient landmarks, and traditional-style urban neighborhoods were razed in the pursuit of new land for building these new developments.

But for some time now there has been a budding consciousness among some urban designers, architects, and government officials that China’s brand of urbanisation was far from optimal — socially, economically, and environmentally — and that the country must build its cities differently. To this end, the central government stepped in to deliver this new set of urban development guidelines, which aim to apply principles of sustainable urban development to all cities across China.

“These new standards are an urban design revolution,” says Peter Calthorpe, a principal at Calthorpe Associates, an architecture firm that has been working to improve China’s urban areas. “They overturn the destructive Chinese model of superblocks, gated communities, and giant streets that has been too long eroding the livability their cities. [The authorities] have been testing these ideas for years, but now they are moving them to a scale that is unprecedented.”

These new guidelines support many urban design strategies that have been developed successfully in many cities around the world, such as New York, London, and Copenhagen. More specifically, these guidelines bring the following seven areas into focus:

1. Denser street networks

At the root of these urbanisation guidelines is a revamping of the street layout in urban areas to improve the transportation network, increase walkability, create space for more street-facing shops, and enhance the social fabric of urban neighbourhoods. This process will be partially carried out by breaking up superblocks with narrower, one-way streets, as well as opening up and phasing out gated communities.

This last move has been highly controversial in China.

“For the discussion right now about the gated community, I really think that it should not be about how to take the walls down, which we have heard so much about recently,” said Wen Zhao, an associate partner at ZGF, a design firm that has been experimenting with open neighborhoods in China since 2006. “I rather see this as a new urban design movement focusing on how to create a new type of open neighborhood that work with the local lifestyle and culture.”

2. Enforcing urban growth boundaries

Over the past couple of decades, China’s cities have been swallowing up large tracts of countryside as they grow to many times their former sizes. At the height of the urbanisation boom, over 2,000 square kilometres of rural land was being requisitioned annually for new city building.

The sheer size and scale of many of these urban expansion projects is almost inconceivable: Shanghai increased its area sevenfold in 15 years; Dantu, a new area of Zhenjiang, is 748 square kilometres (about half the size of Greater London). Chenggong in Kunming is 461 square kilometres; Tianjin’s Binhai New Area comes in at 2,270 square kilometres; and Changzhou, in Jiangsu province, has one new district the size of Los Angeles and is working on absorbing another which is larger than London.

Despite having large populations, this rapid expansion means that many Chinese cities are less dense than they could – and, some say, should – be. Under the directives of these new guidelines, growth boundaries will be instituted to curb urban expansion. This is intended to preserve land for agriculture and to promote more sustainable, less resource-intensive, compact development.

3. Expanding mixed-use development

The new urbanisation guidelines encourage mixed-use development and recommend that all residents should have improved access to a diverse range of public and commercial amenities – schools, supermarkets, retirement centres, hospitals, parks, and cultural centres – within range of where they live. There is a special emphasis on green space: the guidelines decree that all city dwellers should have access to public parks, gardens, and other open areas.

“To build a healthy living environment, we have to actively create a new zoning guideline,” said Wen Zhao. “The current functional zone approach, like sports zone, medical zone, etc., in many cities is not the best solution for increasing the performance of the city or communities. I believe that the concept of mixed-use is the better solution.”

One article from a user with the handle “Pretending to be New York” on China’s popular WeChat compares New York City with Beijing.

“The convenience of Manhattan is difficult to imagine without experiencing it first-hand. Within two minutes of my apartment, I can reach the metro, Starbucks, supermarkets, movie theaters, office supply store, gym, furniture store, bookstore, library – anything you can think of,” the user wrote. “This megacity has the same conveniences as a small city in China. When you compare Manhattan to Beijing, where it can take 10 minutes to cross a road because you have to take a pedestrian bridge or walk underground, Manhattan really seems like heaven, and is truly a city built for people.”

4. Increasing the prevalence of public transportation

The new guidelines also emphasise the need for a diverse mix of public transportation options, including light rail, buses, and subways.

Although China already has a relatively effective bus system, and is working to build over 7,000 kilometres of new subway lines in cities across the country by 2020, the new guidelines call for enhancing these networks even further to ensure everyone within an urban centre is always within 500 metres of public transportation.

5. Historical preservation and city character

The calamity of China having so many cities that look virtually identical, and the wholesale destruction of historic areas, has not gone unnoticed. To salvage what is left of the country’s architectural legacy – and to encourage more diverse styles of building – these guidelines include an entire section about the cultivation of what they dub “city character.”

In practice, this means preserving historic architecture, retrofitting old buildings, revitalising older urban areas, and enhancing “cultural continuity” by reviving the long and unique histories of each city.

6. Improve urban architecture quality and construction methods

It has often been stated that the average modern building in China has an expected lifespan of 25 to 30 years – far less than the 74 year lifespans of US buildings and the 132 years of those in the UK. There are many reasons for this: poor design, lack of maintenance, and the use of shoddy building materials.

So this is another woe the new guidelines will attempt to remedy. The guidelines also mandate more efficient and environmentally beneficial building techniques; construction waste and pollution will be cut, building times will be shortened, and within 10 years, 30 per cent of all buildings constructed will be pre-fabricated.

7. Expand energy efficiency and environmental quality in cities

Over the past decade, China has been experimenting with less environmentally pernicious forms of urbanisation, with varying results.

These new guidelines have taken green building and urban planning to a new height by decreeing that government buildings have energy-efficient lighting and other low-carbon technologies; that new buildings must have meters for heating; that water-efficient “sponge city” development should be expanded; that natural environments in urban areas be revitalised; and that air and water quality be restored.

According to these new mandates, by 2020 all cities from the prefecture-level up should treat 100 per cent of their wastewater, and water-scarce cities should reuse 20 per cent of their water. The guidelines also outline that, by 2020, waste reuse should top 35 per cent across the country.

In general, these guidelines are intended to repair the mistakes wrought during China’s recent era of rampant urbanisation and to set a more environmentally, socially, and economically sound course for urban development in the future.

China’s development will no longer revolve around the profit-centred mindset of building anew as fast as possible. Instead, it will focus on improving and revitalising what’s already there. It’ll turn the country’s cities away from their dystopian trajectory and into socially dynamic, community oriented, healthy, convenient, and sustainable places to live and work.
