In December 2010 the council consulted on a document titled the Birmingham Core Strategy Consultation Draft which proposed that the city deliver up to 50,600 new homes up to 2026.
However, the council said that since then changes had occurred which meant it needed "to revisit aspects of our approach relating to housing and jobs". These include the publication of the National Planning Policy Framework (NPPF) which it said placed new emphasis "for each local authority to produce an up-to-date development plan that meets the needs of their area".
It added that "this agenda has been accompanied by a move away from regionally determined targets for growth to an emphasis on the assessment of objectively assessed needs driven from the local authority level".
The council also said that new population projections had predicted a sharper rise in the city’s population that previously anticipated.
The new document says that the council’s approach is to "provide for as much of the city’s growing population within the urban area as far as possible." However, it adds that: "The urban area therefore has limits on the amount of available space and as a result there is likely to be a shortfall of land to accommodate in the region of 30,000 dwellings in order to meet future needs. Options beyond the urban area need to be explored if we are to plan positively for the future."
"This means that it is necessary to explore the release of land from the green belt for housing development."
The council added that in addition to considering options within Birmingham it is also "working proactively with neighbouring authorities" through the Localism Act’s duty to cooperate "to share some of the housing requirements, as has been the case in the past."
Birmingham Development Plan Planning for Birmingham’s growing population is out for consultation until 14 January 2013. The document can be read here.
