Jenny Hall said "Are there any best practice guidelines or methodologies for how such areas are derived? The drawing of such boundaries always seems very subjective to me. How do you make those boundaries defensible in a public inquiry for instance? (Apart from it's there because we say so.)" EUS and HLC studies following EH format "fomalise" the process of defining the areas (not necessarily the boundaries) of interest. If these areas of interest are incorporated into Supplementary Planning Guidance, Development Briefs, Local Plans, or Spatial Strategies, then the information becomes defensible at public inquiries. Mind, to change the boundaries or areas of interest may take a number of years (up to 10 or 15 in the case of Local or Regional plans). You don't need to provide hard line graphic boundaries either: one of our Local Plans merely describes in text two areas and their interest. As long as something is in a formal plan or planning guidance, it is much more easily defended.
