The handling of individual applications for development on land which is known or suspected to be unstable or potentially unstable will need to take account of the potential hazard that such instability could create both to the development itself and to the neighbouring area. Whilst there is scope for flexibility, and each application must be treated on its merits, it is important that the local planning authority is satisfied by the developer that any instability has been taken into account.
The causes of ground instability fall into three broad categories: the effects of underground cavities; unstable slopes; and ground compression.
