As much as 160 hectares of the seabed off Tung Chung on Lantau Island could be filled in to create land for massive residential developments and possibly a theme park.
The reclamation, which officials term a new town extension project, is among studies to be conducted to find land for future housing.
With further reclamation of the harbour largely banned by law, the government is eyeing the New Territories' coastline for new sites.
According to a document tabled at a Legislative Council joint panel meeting yesterday, the Tung Chung project would involve reclamation east and west of Tung Chung new town. Some 120 hectares would be used for property development.
'Residential uses will be the major component of the proposed development with ancillary commercial uses, community facilities and open spaces,' the paper, prepared jointly by the Planning Department and Civil Engineering and Development Department, said.
A further 40 hectares of reclaimed land would be reserved for a theme park or other large-scale recreational use under a long-term concept plan.
