The Wirral Society, who represent CPRE on the peninsula, have long highlighted the threats to the Green Belt from high population and employment figures put forward in the Local Plan; these figures have been challenged by CPRE as recently as October 2018, using evidence from Professor David Gregg, Graham Stevens and other respondents to demonstrate that levels are much higher than necessary. Now, CPRE Planning Officer Jackie Copley has conducted research alongside the Wirral Green Space Alliance, finding that the number of brownfield sites available on the Wirral has been under-recorded; land that could potentially site 14960 dwellings currently awaits development, which could drastically reducing the pressure on sites in open countryside.
