Policy GD2 contains a number of ambiguities which are unlikely to assist the interpretation of policy in a Development Management context. For instance, it is unclear at what point additional housing would be deemed to have "significantly exceeded" the target for delivery of new homes within a particular settlement. The supporting text refers to 10% or more growth as being excessive as a "rule of thumb", however this is considered to be arbitrary, wildly imprecise, unsupported by any detailed, technical evidence or endorsed in national policy and guidance. Moreover, restricting growth to 10%, whatever the local circumstances, is at odds with the overriding objective of delivering a minimum of 12,800 new dwellings over the Plan period.
