TÁC GIẢ Part | ARCHITECTURE Lesson 1 PLANNERS OF SAIGON SOUTH PROJECT SOM’s Planning Studio in San Francisco originally focused on the conversion of ranchlands in Southern California and Texas into new urban centers like Irvine near Los Angeles and Las Colinas near Dallas. These very large holdings - literally tens of thousands of acres - were planned for long-term growth. Our role as planner allowed us to track their development and intervene periodically to address specific problems. Over time, we saw quite consistently that the "freeway scale" of these new communities undermined their human scale.
Despite rapid growth, substantial wealth and the presence of important “anchors” like a new university, these communities lacked a sense of place. As they grew, we finetuned our plans to add density, improve access to districts and neighborhoods, and - most impor- tantly - to create "walkable" neighborhoods that encouraged people to leave their cars. We started working in Asia in the late eighties - initially, in Bangkok and Jakarta. These two cities, famous for their "gridlock", taught us some immediate lessons in how quickly car and' motorbike traffic can overwhelm cities that were not designed for them.
At the same time, we were impressed by the pedestrian scale of their older districts. Despite their congestion, they teemed with life. Yet many of them had already been disrupted by Western-style development. Tall buildings and oversized shopping malls were placed almost randomly across these cities, with no apparent awareness of their impact on traffic and on the "quality of life" of neighborhoods and districts.
Because our practice is in San Francisco, one of America’s more beautiful cities, we also had considerable experience planning new development within historic districts and in areas of great environmental sensitivity. In Asia, we saw by contrast how Singapore had eradicated its own history as it modernized - to the point that it had to rebuild some of its older districts. Elsewhere, we saw the steady erosion of the natural setting - with hillsides, canals and agricultural greenbelt sacrificed to rampant, unmanaged growth. In Hong Kong, though, we saw how the development of the New Territories preserved the larger environment.
A new town like Shatin, the size of Boston, provides a density that makes public transit viable - so that few people commute by car. Compact, highrise development of this type protects the surrounding hillsides, so that virtually every apartment enjoys a view out to unspoiled nature. Because of this experience, what we brought to our new projects in China and Vietnam was threefold : e From our U. experience, a sense of the importance of density, accessibility, and a pedestrian - human - scale.
e From our Asian experience, a sense of the vulnerability of the traditional Asian city "fabric’ - its historic pattern of development - to unmanaged modernization. e Also from Asia, the sense that growth could be managed with proper planning - and that discovering how to manage growth appropriately was perhaps the biggest challenge facing us in our Asian projects. Not surprisingly, we found that many Asians shared our views. Our Vietnamese clients for the Saigon South project, for example - planners and other officials with the Ho Chi Minh City government - were well aware of the problems of Bangkok and Singapore.
This awareness gave them a strong sense of what to avoid. While they might desire Western-style buildings, they understood that these alone would not give them a modern city - let alone a city rooted in their own culture, climate and traditions. In 1993, SOM won an invited competition to plan a 6,300 acre area directly south of the historic center of Ho Chi Minh City. This area, now known as Saigon South, will extend the existing city to provide modern buildings and infrastructure - as well as employment and housing - for a million people.
The project is a good case study of how technology transfer in the field of urban. development works in practice in this Southeast Asian country. Despite the City’s growth in the years of American occupation in the sixties and early seventies, the agricultural areas to the south and east remained undeveloped. By the early nineties, as _ Vietnam resumed trade with its former enemies, the question of extending the City became more pressing.
The basic options were to : e Redevelop the existing City at a higher density, which could put its unique fabric - the product of French colonial and merchant Chinese influences - at risk. e Push east ~ a step that would require tall bridges over the heavily - used Saigon River. e Push south - a natural extension of the City that also linked to a new deepwater port and industrial zone southeast of the Central District. The City opted to push south.
They also joined forces with a Taiwanese company, the Central Trading & Development Group (CT&D), that is also a major investor in the new industrial zone near the port. This joint venture, the Phu My Hung Corporation, is our client for the project. Ho Chi Minh City is a charming city with low buildings and substantial open space in the form of parks and tree-lined boulevards. Rivers, canals and waterways are an important feature - unlike Bangkok, they have not been paved over.
In its vision of Saigon South, our client wanted very much to bring forward the traditions of the older city. They wanted to preserve what exists now ~ the historic districts of Ho Chi Minh City and the unspoiled agricultural greenbelt that adjoins it to the south and east. Yet they also wanted to restore the city as Vietnam’s commercial center, its "gateway" to the world economy. The new community of Saigon South, as modern urban center, will provide this transformation without harming what is unique and irreplaceable in the older city and its region.
Although we won the competition, we were also attractive to the client because of our specific knowledge of urban-scale development elsewhere in the world. Unlike some of our competitors, we had acually implemented many of these projects - the advantage of also being both architects and engineers. In addition, we brought an important set of tools to the project - tools that were not available to the City government or to local planners. For example, the City’s government lacked the technology to evaluate the impact of the project on regional water quality.
Our team’s hydrologist, Woodward-Clyde Associates, provided this analysis using a modified version of a U. Environmental Protection Agency simulation program that can model a regional water "eco-system". We used this computer-based model to test the impact of restoring 10 and reopening canals and waterways across the new project. In this way, we were able to arrive at planning solutions that improved water quality substantially in the region.
The City also lacked an adequate regulatory structure for guiding development. Zoning and building regulations were substandard or non-existent. Our plan provided a "framework" of planning and design principles for the project that provided the basis for City-enacted zoning requirements for the area. Some examples of these principles are : Compactness Development should be concentrated in centers to ensure an appropriate density, preserve open space and support public transit service.
Boundaries Development should occur only within well-defined areas with clear boundaries. Walkable neighborhoods Neighborhoods should be compact enough to encourage people to walk. A maximum width of 1.5 km makes for a walkable setting. Linked development and transportation Major arterial roads and transit corridors should be designed so that they can be easily upgraded in capacity and service as development occurs and demand increases.
Landbanking Expansion areas within each center (including transportation corridors) should be landbanked initially, allowing their interim use by the community while discouraging inappropriate development. 11 Preserving the larger setting The larger ecosystem of agricultural land, navigable rivers, canals: and smaller waterways should be preserved and improved as part of the development process - both as an amenity and to maintain regional water quality. As Saigon South began initial construction, we also helped the City to modernize its existing building code-first, by comparing it with U. and European codes, and then by recommending one of them (America’s Uniform Building Code) as a potential standard.
