PPG14 Development on Unstable Land

This PPG explains briefly the effects of land instability on development and land use. The responsibilities of the various parties to development are considered and the need for instability to be taken into account in the planning process is emphasised.

Methods of doing this through development plans and development control are outlined. The role of expert advice is highlighted and various causes of instability are explained and sources of information are given.

Separately published Annexes on Landslides and planning and Subsidence and planning develop this advice with specific reference to those areas and include background information and good practice guidance on identification and assessment of these problems and how they are can be dealt with in the planning system (Original release date April 1990)
