Description: CGA were the result of the urban expansion exercise undertaken for the 2006 Structure Plan. There was a requirement for additional land release over and above the brownfield allocations made in the Plan in order to meet the Agenda for Sustained Growth through a requirement for 19,000 houses, predominantly in greenfield locations. An urban expansion exercise was undertaken in 2005 and a detailed methodology can be found in Technical Report TR 6/06 Assessment of Potential Areas for Urban Expansion. The outcome of the assessment was 13 CGAs across the Structure Plan area. These boundaries indicate the initial search areas which are subject to change through local authority master planning as part of their local Plans. For more detailed boundaries on master plan areas please contact the relevant local authorities who will be at different stages in the master planning process.
