Suitability of Cavern Development

The hilly terrain and geology of Hong Kong offer excellent opportunities for rock cavern development. In 2011, the Civil Engineering and Development Department developed a cavern suitability map that delineates areas considered suitable for developing rock caverns throughout the territory. The map shows that about two-thirds of the land area of Hong Kong is suitable for rock cavern development.

Conservatively assuming that 5% of this area could be made available for rock cavern development, this could provide some 3,500 ha of developable land (equivalent to about 180 nos. of Victoria Park).
