Local Plan Policies on Ground Stability and Subsidence - Public forum - Planning Advisory Service (PAS)

Has anyone any good examples/experience of site specific Local Plan policies on this subject?

Both the PPG (http://planningguidance.planningportal.gov.uk/blog/guidance/land-stability/) and the NPPF (paragraphs 109, 120, 121, 143, 166) appear put a strong emphasis on planning addressing this issue, including as part of the process of making allocations.

In particular, the PPG states that ‘Consideration of land stability in local plans will vary between areas and the types of issues that the plan covers, but planning authorities may need to consider: Identifying specific areas where particular consideration of landslides, mining hazards or subsidence will be needed;’

There are several useful info sources on this including:

• British Geological Society mapping of areas of potential for geohazard
• Maps of Mined Areas, natural underground cavities, soluble rocks, ground compressibility, etc (all published in the old PPG14, Annex 2  http://www.wyreforestdc.gov.uk/media/115148/NP17b-PPG14-Unstable-Land-Annexe-2-Subsidence.pdf)

It would seem a logical policy requirement for development in such areas to include a ‘ground stability assessment’, but I have yet to see any examples of such policies linked to mapping.

Any advice or examples would be much appreciated.
