Gundu was presented as a case in SGT (Sustainable Global Technologies / Helsinki University of Technology) for a half-year research and
design task for a cross-disciplinary croup of river engineers,
architects and applied arts and future studies. The group ended up with
a draft master plan for the future Guandu with approximately 150.000
citizens living and working in a river city.Guandu RiverA new man-made
river will be created through the Guandu plain providing clean water
for the future residents. The new Guandu River will take most of its
water from the polluted Keelong River and also collects streams from
the surrounding mountains. The 7.2 km long river will act as a
biological filter with different vegetation and filtering layers
purifying the river water for residential use. The last part of the
Guandu River with clean water is opened for recreational purposes
having a beach and a holiday village.Guandu PlainThe existing
Danshui-Taipei highway will be moved into a waterproof double tunnel
under the Guandu Plain in order to create a larger unified ecological
area. Now the highway is splitting the Guandu plain in two halves. The
Guandu plain is partly naturally restored and partly used for urban
farming and biomass production. Bio-energy is recognized as a suitable
source or renewable energy. Biomass will be grown first in the Guandu
plain area and later along the Danshui and Keelong River flood banks.TrafficAn elevated Light
Rail train will connect the different Guandu areas with the existing
MRT network. Busses will serve areas where the LR or MRT stations are
beyond a convenient walking distance. The existing bicycle and
pedestrian routes are reinforced to include all the future Guadu.Built human environmentThe
River City Guandu is based on the principle of free flooding. This
means that there will be no floodwalls in the future Guandu, but
architectural and infrastructure solutions will be reactions on the
free flooding. The built areas will be elevated on 10 meters high
landfill islands created by the highway tunnel and Guandu River
constructions. Some of the housing will be floating.Organic layersThe Guandu plain will be connected with the surrounding mountains with ecological corridors.Urban
farming will be a characteristic feature of the river city. Community
gardens will extend to all areas of built environment.Biomass production is viewed as a positive factor for the Taipei’s microclimate and as a source of renewable energy.The wetland and mangrove nature is protected and other parts of the Guandu plain are naturally restored.ConclusionGuandu
has the potential to be a world-class example of environmentally
sustainable river urbanism. The urban solutions proved in Guandu will
benefit the general ecological restoration of the Taipei Basin.
UN-HABITAT could be considered as a partner for the Guandu development.New
kind of round table discussion methodology and participatory planning
should be developed around the Guandu case in order to start
cultivating the next generation knowledge building towards the third
generation city.The industrial-modernist solutions cannot be
applied straight in the planning and development of Guandu.
Industrialism has forgot the local knowledge and lost the social drama
of the city. Guandu should turn back towards the local knowledge and
forget the forgetting.Sustainable Global Technologies Team:Lasse Granroth (TAIK, applied arts and future studies)Hanna-Sisko Hovila (TKK, architecture)Francesco Mandrilli (Italy, water engineering)Teemu Nurmi (TKK, water engineering)Iina Valkeisenmäki (TKK, architecture)Mentors:Marco CasagrandeFrank ChenSGT Cordinators:Matleena MuhonenPamela ArslanbayrakSGT Director:Prof. Olli Varis
