You may recall that in the build up to the General Election, Grey Belt was simply referred to as a means of developing under-utilised brownfield sites within the Green Belt which cannot be developed on solely as a result of their location within the Green Belt e.g. petrol stations and hard standing, as discussed in our briefing here. This was likely a deliberate attempt to play down its significance, given the adverse publicity expected in response. However, the definition of the Grey Belt provided for in the NPPF is much broader than the limited examples provided by the Government last year, and its effects are also potentially more significant that what appeared in the consultation draft previously published.
Paragraph 143 of the NPPF sets out the purposes of the Green Belt as follows:
a) to check the unrestricted sprawl of large built-up areas;
b) to prevent neighbouring towns merging into one another;
c) to assist in safeguarding the countryside from encroachment;
d) to preserve the setting and special character of historic towns; and
e) to assist in urban regeneration, by encouraging the recycling of derelict and other urban land.
The fact that the definition of Grey Belt land does not take into account the purpose set out at paragraph 143(c) is particularly noteworthy. Rather than protecting the countryside from encroachment, the key consideration is whether the identified land within the Grey Belt contributes towards preventing urban sprawl/the merging of towns and the preservation of their character. Furthermore, even if the identified land does contribute towards preventing such encroachment, the land must "strongly contribute" to this purpose to avoid potentially being classified as Grey Belt. It is also important to bear in mind that individual sites will be assessed against this broad definition of Grey Belt as part of individual planning applications. For example, if a planning application identifies a single field for development which forms part of a group of much larger fields which will not be affected by the application, it would seem difficult to argue that the single field identified in the application strongly contributes to any of the purposes in paragraph 143 of the NPPF.
So, what does it mean if land within the Green Belt can be classified as Grey Belt? Crucially, there is a general presumption that development within the Green Belt is inappropriate whereas paragraph 155 of the NPPF now provides that:
