Stages 1 and 2 contain preliminary planning and scope of the assessment, determining which land types would be excluded from the assessment, which land types would be included and have a potential source of housing. ii Stages 3, 4 and 5 identify 325 sites from the various sources and assess them for their suitability for housing. This resulted in 241 sites being considered unsuitable, and 84 of the sites being considered suitable. The full range of sites considered are shown in Appendix 12. iii Stages 6 and 7 summarise the 84 suitable sites and estimates their housing capacity as well as their availability, achievability, constraints, developability and deliverability. iv Stage 8 contains a review of the assessment and sets out the land availability in Oxford in comparison to housing targets. There are two ways in which targets need to be measured. Firstly, against the Oxford’s target of 8,0002 dwellings between 2006-26 (400/yr), the SHLAA indicates that there would be an overall shortfall of 2,108 dwellings (26.3%) when windfalls are not included (Table 19). v The second measuring tool is to show that enough deliverable sites can be identified to meet the housing target for the first five years from adoption of the Core Strategy (2009/10-2013/14). The SHLAA shows a skew towards identified sites coming forward over the earlier years and it indicates that the 2,000 (400x5yrs) target of deliverable sites for years 1-5 from adoption of the Core Strategy, will be exceeded by 32.2% (Table 19). This skew also means that Barton is not required during years 1-5 but that it would be required during years 6-10 as demonstrated below. Executive summary figure: Diagram illustrating position of Strategic Sites based upon 400/yr target and PPS3 time period requirements. ‘Deliverable’ sites are those available now, suitable and achievable. ‘Developable’ sites are those suitable and available at a later date (full definitions at paragraph 7.2) 1 Strategic Housing Land Availability Assessments: Practice Guidance (Jul 2007) CLG 2 Secretary of State’s Proposed Changes to the South East Plan (17 July 2008) CLG 7 Oxford’s Strategic Housing Land Availability Assessment August 2008 vi The assumptions regarding when strategic sites will be required should be revisited each time the SHLAA is reviewed as they are dependant on other identified sites in the SHLAA coming forward.
