Policy G9 Geodiversity


  1. In Development Plans, boroughs should:
    1. establish clear goals for the management of identified sites to promote public access, appreciation and interpretation of geodiversity
    2. ensure geological sites of European, national or regional conservation importance are clearly identified.
  2. Where relevant, development proposals should
    1. make a positive contribution to the protection and enhancement of geodiversity
    2. protect Regionally Important Geological Sites (RIGS)
    3. give Locally Important Geological Sites (LIGS) the level of protection commensurate with their importance.

Geodiversity is a fundamental cornerstone of our everyday lives. Geology affects where we build, how we construct buildings and how we deliver associated services. It influences the design and layout of infrastructure, filters our drinking water and underpins the landscape around us. Geodiversity cannot be replaced or recreated (other than on geological timescales).

National planning policy is clear that boroughs should protect, promote and enhance geodiversity. London’s geodiversity sites are shown in Figure 8.1. Geodiversity sites with existing or proposed European or national designations are Sites of Special Scientific Importance and subject to statutory protection. Boroughs should protect and enhance RIGSs and LIGSs through their Development Plans. The Mayor will continue to work with the London Geodiversity Partnership to promote geodiversity and will prepare updated Supplementary Planning Guidance as necessary.

Geodiversity sites should be recognised for their importance in providing habitats for biodiversity and in allowing delivery of ecosystem services.

Where appropriate, access for all should be provided to geodiversity sites, although it is recognised that this is not always desirable. Geological sites will require appropriate maintenance regimes to ensure that these assets are properly protected and managed.
