The population of Tung Chung will more than double to 275,000 in 12 years under a proposed development plan that will reclaim nearly 135 hectares of land.
A Development Bureau spokesman revealed this while launching the second phase of a two-month public consultation on development in Tung Chung, which currently has a population of 121,000.
The bureau plans to build two new MTR stations in Tung Chung East and Tung Chung West.
In addition, 120 hectares will be reclaimed in Tung Chung East and 14 hectares in Tung Chung West.
A spokesman for the bureau said there are two initial land-use options for Tung Chung East. One is a "Liveable Town" with residential areas and commercial areas planned around the MTR station. There would be about 38,000 flats for a planned population of around 111,000.
The "Economic Vibrancy" option would create a regional commercial hub alongside 33,000 flats for a population of 95,000.
About 450,000 square meters of floor area will be planned for office, regional retail or hotel use.
A 350-berth marina with related land for commercial uses is proposed.
The spokesman said as Tung Chung West is relatively rural and has eco-sensitive areas such as Tung Chung River and its estuary, only 14 hectares would be reclaimed.
The spokesman said the bureau found rare species such as horseshoe crabs and Romer's tree frog, but believes reclaiming outside of the river will not affect the ecology.
About 15,000 flats will be built, for a planned population of about 43,000.
The existing public to private housing ratio in terms of population is about 56:44.
Under the proposal, the ratio of public housing to private housing will be four to six.
The reclaimed land will be completed around 2021. Flats would be built three to five years later.
Bill Tang Ka-piu, Islands district councillor of Yat Tung Estate North Constituency, said the two new stations would assist district development. However, he fears expensive fares will deter people from moving to Tung Chung.
He called on the government to make the Lantau Link toll-free to lower transportation costs.
WWF marine conservation officer Samantha Lee Mei-wah is worried that large- scale reclamation will endanger Chinese white dolphins.
