Planners are scratching their heads over how to link the former airport site at Kai Tak to neighbouring areas without contravening environmental laws. Acting assistant director of planning Raymond Lee Kai-wing told the third stage of the review of the redevelopment plan - which closed with more than 90 submissions - that the overall consensus was for a connection between Kai Tak and the surrounding area. The old runway is separated from Kwun Tong by a 500-metre stretch of water, or nullah. 'The majority want a low-density development and many people want to be able to access the harbour,' Mr Lee said. 'At the moment, there are some difficulties. If you think of building a bridge, government lawyers are of the view that that is reclamation,' Mr Lee said. 'Any plan needs to comply with the Protection of the Harbour Ordinance. 'To have reclamation there needs to be an overriding public need. We cannot identify any overriding need.' Chan Kam-lam, of the Democratic Alliance for the Betterment and Progress of Hong Kong, said the party had consulted some environmental groups that did not believe building a 500-metre connection would constitute reclamation. In its submission, the DAB also suggested building an observation tower at the tip of the runway and a bridge linking the site with Kwun Tong. But the Civic Party's Ronny Tong Ka-wah said a bridge was likely to be considered reclamation. His party yesterday submitted its views to the government, opposing plans to build a heliport at the tip of the old runway. The party said this would waste a site that offered a panoramic view of the city and would have noise implications for the surrounding area. 'If you have a heliport there to serve the Pearl River Delta, you are talking about helicopters landing and taking off every five to 10 minutes and that can be very noisy,' the Civic Party's Alan Leong Kah-kit said. The party also criticised the plan to build a 40,000-seat stadium, saying it would waste up to 10 hectares. 'There is a plan for a stadium because [Home Affairs] Secretary Ho Chi-ping wants one,' Mr Leong said. 'They have included about 10 hectares of surrounding land to provide space for crowds to disperse. Then the Leisure Services Department wants to build parks in addition to that. This is already a waste of 10 hectares.' Mr Leong also warned against developing the site without reference to the site's history. 'If people cannot remember in 30 years that this was formerly an airport, it defeats the purpose of the redevelopment plan.' He said the government was not giving enough thought to integrating it with old surrounding neighbourhoods such as Kowloon City, Ngau Tau Kok and San Po Kong.
