100 hectares needed for Lantau checkpoint The government is planning to reclaim up to 100 hectares off northern Lantau for the construction of a control point for the Hong Kong-Zhuhai-Macau Bridge, which green groups fear could cause irreversible environmental damage. The amount of land required - 21/2 times the size of the West Kowloon cultural district - would make it the largest reclamation project since Penny's Bay was reclaimed for Disneyland in 2000. Environmentalists say the marine ecology - from endangered Chinese white dolphin to rare horseshoe crab habitats - might be affected and the remaining untouched coastline on north Lantau would be spoiled. Sources close to the government said it had initially been estimated that 90 to 100 hectares would be needed to accommodate the immigration and customs facilities - similar in size to those at the new Deep Bay border crossing - as the bridge would bring heavy traffic, particularly freight, across the border. While officials had no definitive plans for where to put the control point, they admitted there were few options, the sources said. Because of the shortage of flat land along the northern Lantau coast there seemed little choice other than reclamation. The sources said one option was to build the control point on a piece of land at the entrance of the Tai Ho Valley, part of which has been designated a site of special scientific interest for its freshwater stream ecology. Another option was the sea off Sha Lo Wan. It remained unknown how the new facilities would fit in with the logistics park or Container Terminal 10, which are also proposed for the northern or western Lantau shore. The sources said transport officials had recently 'restarted' stakeholder consultations about the 35km bridge spanning the Pearl River mouth, hoping to gauge public sentiment about reclamation options. The reclamation became necessary after Hong Kong and the mainland last year ruled out building joint immigration facilities for the three jurisdictions on reclaimed land near Macau. Instead, each would be responsible for building the facilities in their own territory. 'It seems to be a very big area indeed, and doubtless a far more costly option than the single facility at Deep Bay. It will be very difficult to shoe-horn this [facility] in without causing yet more environmental damage,' Green Lantau Association spokesman Clive Noffke said. Instead, Mr Noffke proposed building an island east of the airport, saying this would avoid taking up coastal land, help move the bridge away from Tung Chung and enable a direct connection to the proposed Chek Lap Kok-Tuen Mun link. A Transport and Housing Bureau spokeswoman would not comment on the size of the control point or the reclamation it would require, saying it was being studied as part of the feasibility study for the bridge. A detailed proposal for the location and arrangement of the facilities would be drawn up in due course.
