Super Green Road (SGR)

Lai'an, China

What is the city of the future? How will our park systems tie into the urban planning? How can we begin to create a new idea of public space for our cities of tomorrow?

BAM developed the idea of the SUPER GREEN ROAD with a leading developer in China with the scale and experience to accomplish planning of new cities. It works something like this. Average new cities are dedicating 8 % of their total new areas to green space. In a typical city these green zones are sprinkled around the city in order to make them accessible to the many inhabitants in all of the districts. The center of each city usually contains the largest green area and often has cultural programs attached.

BAM saw this as an opportunity. We said what if we can create a large loop within the overall city plan that connects and links these green nodes like a necklace—(not dissimilar to Olmsted’s parkway in Buffalo or Boston.) But because today’s cities are not just about traditional green spaces for public areas, we also tie it into retail zones and plazas. By linking all of these public spaces together we form a large scale public landscape. The SUPER GREEN ROAD.

But the SUPER GREEN ROADs goal is to transcend the large-scale planning issues and create a sensation of detail, of humanness that connects the inhabitants of the new city. So we use a fractal idea, wherein the largest loop plugs into town level loops. Town level parks connect to town plazas within the larger city loop. And it doesn’t stop there---we also envision a smaller scale in the fractal, the community loop, where within a single community the public space will have its own nodes and connect to the larger scales.

How can we implement a fractal idea in the overall planning of the landscape? For BAM it was the observation that in a good walk outside we should have certain elements. A trash can. A light, trees. Etc. Older people should be able to sit down and rest every minute of walking. Dogs need space to run. Kids need playgrounds. Public needs bathrooms. Communities need green spaces. Towns need parks. Schools need sports facilities.

BAM developed a model to start to locate the important programs on the super green road necklace as a piece of infrastructure.

After modelling out these programs and repeating them in loops, we started to see overlaps. Seniors can rest in areas that kids play. Sports can be combined near the commercial zones. This efficiency created a public space that was multifunctional and operated in different ways at different times of day.

THE SUPER GREEN ROAD concept was developed in a model city, but also BAM has had the chance to test out the SUPER GREEN ROAD on real cities that are on the drawing boards. The lucky city of the three cities BAM has had the chance to work with for the SUPER GREEN ROAD that is starting construction is occurring just north of Nanjing in Lai’an Anhui.

All planning begins with an ecological basis. For BAM the GIS overlay of the local hydrology indicated which regions of the urban plan should remain as important watersheds and river corridors. With the city planners and the ecological consultants BAM devised a large SUPER GREEN ROAD loop that activated riverside park and wetlands zones, connecting theme into a large public space network!. WOW!

But in some zones there was no ecological basis for designing a park. This is the zone where bam started from, to create a 2km link between the natural ecological river zones. So for BAM the SUPER GREEN ROAD exercise was creating an urban public space link which would connect people from their homes, schools, shopping areas, to the ecological recreational zones.

Because this entire city was unbuilt at the time of design BAM used the planning ideas and the developers vision for the area to organize SUPER GREEN ROAD programs that enhance the surrounding plots. Residential plots have gateway entrances into the biking and walking paths. Adjacent to school areas we include playgrounds. We create places for older people to rest or socialize at close distances to their living areas. Near commercial zones we create plazas and sports grounds, louder more active programs.

But the LAIAN SUPER GREEN ROAD is built for the future. We have imagined the occupancy of the town once built and built out for them programs to suit the future population size. At the moment we only see a small portion of the SUPER GREEN ROAD. These are only 2 plots—BAM has completed the DD drawings for the first SEVEN!!! Wow!

One of the amazing parts of the SUPER GREEN ROAD landscape is that it is already working even though there are not really houses nearby. Kids from the adjacent school spill out onto the playgrounds. The local construction workers nap in the shade created areas. While this public space is still forming it can support a great range of activities already.

超级绿道

来安

未来的城市是什么样的?如何将我们的公园系统融入城市规划?我们该如何为明天的城市创造一个全新的公共空间理念?

BAM与国内有着丰富的新城尺度开发经验的开发商一起提出了“超级绿道”的新城规划理念。其原理是: 新城平均有8%的区域用于绿地空间。在典型的城市中,这些绿地会散布在城市周围,以便所有地区的居民可以使用。城市的中心通常建设有最大面积的绿地,也常有文化项目与其相连。

BAM认为这是一个机会,我们可以在城市中创造一个环路,像项链般串联这些绿色节点——正如布法罗或波士顿的奥姆斯特德公园大道一样。但是当今的城市不仅仅是为公共空间提供传统绿化,我们还会考虑将其与商业和广场结合。通过连接这些公共空间,我们将会创造一个大规模的公共景观,也就是“超级绿道”。

“超级绿道”的目标是解决大尺度的城市规划的问题,创造一种细节感,一种连接城市居民的人性化感受。所以,我们利用分形的概念,将最大的环路贯穿于小镇级的环路中,而小镇级环路上的公园及广场就可以通过这个城市级的环路给贯穿起来了。不仅如此, 我们利用分形理论模拟出更小尺度的环路,比如社区级的环路。在每个级别,公共空间都将结合该级别的环道并最终连接到更高级别的环路之中。

我们如何在景观的总体规划中实现分形的理念呢?经过BAM的观察,在外面散步时有些重要的元素是不可或缺的:比如垃圾桶,灯具,树木等等。老年人每走几分钟应该能够坐下来休息;狗狗需要撒欢奔跑的空间;孩子们需要游乐场。公共区域需要卫生间;社区需要绿地;城镇需要公园;学校需要运动设施。

BAM开发的模型开始将重要的功能区域作为基础设施定位在‘超级绿道’项链环上。

首先,对这些基础设施进行模数设置,并按照一定规律在环路上循环布置后,我们发现一些重叠的空间。老年人可以在孩子们玩耍的地方休息;商业区附近也可以进行运动。按照这种规律,我们创造出多功能的空间,在不同的时间段可以发挥不同的作用。

“超级绿道”的概念是基于模型城市开发出来的, BAM有幸能在三个现实的城市中对超级绿道进行验证,其中之一就是南京以北的安徽省来安县。

所有的规划都以生态为基础。BAM利用GIS分析叠加当地水文地理信息,明确了城市中哪些规划区域应该作为重要的流域和河道走廊。在城市规划师和生态顾问的协助下,BAM设计了一个大型的“超级绿道”来激活滨河公园和湿地,并且将这个主题延续到一个大型公共空间网络之中!让人为之惊叹!

在一些区域中,并没有生态基础设施来建立公园, BAM将这里作为起点,在自然生态的河流区域之间创造了一条2公里长的绿道。因此,对于BAM来说,“超级绿道”创造了一个将城市公共空间连接的机会,将人们的家、学校、购物区和生态休闲区连接起来。

因为这个城市在BAM设计的时候还没有建立,所以BAM基于规划和有利于城市未来发展的设想来组织“超级绿道”,以增强与周围的地块的联系。住宅区有通向自行车道和步行道的门户,学校附近设有儿童游乐场,老年人生活区附近设置休息或社交的场所。同时,在商业区附近,我们创造了广场和运动场一类热闹且活跃的功能区。

但来安的“超级绿道”是为未来城市而建造的。我们已经设想了未来城镇占用绿道空间来适应未来人口规模的情况。目前,我们只看到了一小部分的超级绿色道路。虽然现在只建成了前2个地块——但是,BAM已经完成了前7个地块的扩初图纸!!!哇塞!

“超级绿道”一个令人惊叹的地方是,尽管附近还没有建筑,但它已经开始发挥作用。附近学校的孩子们纷纷涌向游乐场,当地建筑工人在景观阴凉处午睡。当这个公共空间还在建造的时候,就已经可以支持大量的活动。
