Nature and the city will come together in plans for three new towns in the New Territories when the Government unveils its first green development model today. Secretary for Planning, Environment and Lands Gordon Siu Kwing-chue will announce detailed plans for Fanling North, Hung Shui Kiu and Kwu Tung North, which will be home to an estimated 340,000 people by 2011. A source said between 10 and 20 per cent of the towns' area would have 'green landscaping' focusing on podiums, riverside and leisure parks. Traditional arches and bridges would also be highlights of the landscape, as would flower gardens. The Fanling North site would have the Ng Tung River running through it. The other two towns would have artificial streams to give a natural feel. 'The idea is to bring nature into city and at the same time bring city into nature,' the source said. It has already been announced that fuelled vehicles would run on sunken roads under platform podiums and residents will be encouraged to travel on trolley buses, moving walkways and electric buses. While pollution from shops and restaurants was inevitable, exhaust devices aimed at lessening emissions would be installed. Mr Siu is also expected to provide overseas examples of green towns. Consultations on the development of the three towns will end on January 15.
