The draft Plan is neither positively prepared nor fully justified, as it proposes the erosion of, and development on, a significant amount of Green Belt, for a housing requirement based on unsound data. The draft Plan does not consider a number of potential alternative brownfield sites, nor housing development sites recently approved. Furthermore, the estimate of future housing requirement has been reached from the Strategic Housing Market Assessment, which was prepared before the EU Referendum vote and does not consider the resulting effect of reducing immigration. It therefore does not demonstrate sufficient need to justify removing Green Belt.
