Land Use Zoning Mechanism for Cavern Development—Re-Thinking the Hong Kong Case
Hong Kong, one of the most densely populated places in the world, has a long history in utilizing sub-surface spaces for different types of uses. Most common examples include the railway, vehicular and pedestrian tunnels, shopping malls etc. With Hong Kong’s hilly terrain and good rock quality, the use of rock cavern has also gained popularity in the last 40 years but has been focusing to accommodate isolated government facilities with low human occupancy. With growing population and the aim to improve livability, cavern areas have been recognized as one of the land supply sources. The Hong Kong Government has injected major resources into the research and investigation to further unleash the potential of this land supply source. Land use planning and technical tools have been introduced throughout the years to facilitate cavern development. Uses of cavern is no longer an isolated development and planning for the use of these spaces is now part of the urban planning process, in particular for new town development. With technological advancement, a wider range of cavern uses has been made possible and an integrated planning approach to consider uses of surface, sub-surface and wider area is being adopted for district- or territorial-wide development. The Outline Zoning Plans formulated under the Town Planning Ordinance provide statutory controls on land use and development parameters at district and local levels. To facilitate the wider and more efficient use of caverns, this paper aims to provide a review on the existing land use zoning practice for cavern developments in Hong Kong. Relevant overseas cases will also be reviewed for best practice and latest trend. The objective is to examine the needs thus measures for enhancement to the zoning mechanism to further facilitate cavern development in Hong Kong.
