Joint Core Strategy Note for the Inspector Subject: Update on Housing Matters Dated: Thursday 3 December 2015 1.0 Introduction The JCS councils have undertaken to fulfil the examining Inspector’s requests for supplementary housing information. This note provides a summary position of the work undertaken on establishing an appropriate OAN for housing and updates the the tasks related to establishing the housing land supply following the note “JCS response to Exam 78” of 7 September 2015 (Exam 112) which provided summary information prior to the publication of the 2014/15 annual housing permission monitoring reports by the JCS councils. This note includes updated housing land supply trajectories and also confirms the findings of work undertaken to establish an appropriate planning permission lapse rate reported in Exam 112. The five year housing land supply calculations for the each of the JCS planning authorities and the JCS included within this note update the summary trajectories shown in Exam 112 and are in conformity with the district’s annual monitoring reports, which have now been published. These trajectories and land supply calculations update those shown in the Submission Housing Background Paper (ETOP 101a) with the land supply position to 31st March 2015. 1.1 Considerable work has been undertaken in establishing an appropriate OAN for the JCS area. Table 1 shows the level of housing development indicated by the different reports over time and provides links to the appropriate reports on the JCS website for ease of reference. Table 2 highlights the findings of the work undertaken on the Strategic Housing Market Assessment (SHMA) and also provides links to the appropriate reports on the JCS website for ease of reference. 1.2 All housing land supply calculations have been prepared in respect of the housing requirements set out in the Submission JCS.

These were provided within Exam 112. However, the JCS councils considered that the actual lapse rate was somewhat lower at approximately 5% and accordingly provided a supplementary 5% calculation. The JCS councils have now completed an assessment of permission lapse rates to help inform the need for a lapse rate to be applied to the five year supply calculation. The findings are summarised below. 2.1 The period of analysis of 2008/09 to 2014/15 was chosen to reflect the availability of data across the three authorities. The research indicates that where permissions do lapse, they are regularly implemented via a new application submitted at a later date. In a number of cases these new applications increase the density of the schemes to enable more homes to be delivered on site. In consideration of this finding, two lapse rate percentages have been calculated. The first is the lapse rate of all permissions regardless of subsequent renewals to the consent; this gives an average 3.0% lapse rate over the seven years from 2008/09 to 2014/15 with an associated median value of 2.4%. The second is the lapse of permissions over the same period but removing schemes that are subsequently superseded and delivered from consideration. The latter approach reduces the lapse rate to an average of 2.5% over the seven year period assessed with an associated median value of 2.2%. The data is summarised in Figures 1 and 2. 2.2 The JCS councils consider that where a lapse rate needs to be applied to the five year supply calculation, a rate of 3% would be more appropriate than 10%. The impact of this 97% implementation rate is commensurate with the 95% implementation rate previously illustrated in Exam 112. Both a 97% rate and a 90% rate have been presented under the five year supply analysis for comparison purposes. The implementation rates have been applied to all sites with consent where development has not yet commenced regardless of site size, as requested by the Inspector. The impact of the 97% and 95% implementation on supply is negligible. A 90% implementation rate would have a minor impact on supply but would still allow the authorities collectively and individually to demonstrate a five year housing land supply for the period 2017/18 to 2021/22 as shown in Section 5 of this note.

This updates the overall housing land supply position to be correct to 31st March 2015 for all sites as shown in Exam 112. In addition supplementary data correct to 31st August 2015 has been included for all sites that contribute to local plan potential to show a clear distinction between schemes with consent that have been guided by the emerging district plans and the further district plan potential. This information confirms the supply data for the JCS presented in Exam 112 and provides the land supply for each authority. 3.1 The trajectory includes revised delivery rates for all development expected over the plan period in accordance with information gathered from the individual district’s most recent Strategic Assessment of Land Availability reports (SALA) published during Spring 2015 and has been supplemented with additional contact with developers of all significant sites to ascertain realistic build schedules in accordance with routine annual monitoring procedures. 3.2 For the JCS proposed strategic allocations, delivery has been harmonised in accordance with the Statements of Common Ground submitted to the examination. The trajectory shown in Exam 112 was also updated in line with the trajectory presented to the inquiry for A4: North Brockworth following the Secretary of State’s “call in”. A schedule of the planning position for all strategic allocations will be made available to the examination during the hearing. 3.3 As set out in ETOP 101a, the Submission JCS trajectory made an allowance for small site windfall development. However, the level of windfall development granted permission in Cheltenham Borough was in excess of expectations in 2014/15 and has increased the overall land supply by approximately 100 units. In addition substantial windfall development has been granted permission in Tewkesbury Borough on larger sites during the 2014/15 monitoring year in light of the authority’s housing land supply position. The majority of the permissions have been granted adjacent to the proposed Service Villages and an allowance had previously been made within the trajectory submitted in support of the JCS for this development. However the small allowance made for development at Tewkesbury town has been supplemented by the grant of permission for a green field site to the north of the town. Three developments delivering approximately 200 units have also been permitted at Ashchurch. Following removal of lapsed consents from the trajectory the overall, updated land supply position has increased by approximately 235 dwellings over the plan period compared with the submission JCS figures. This is a total supply of 31,277 dwellings compared to the 31,042 dwellings in the original submission. 3.4 A further potential supply has been identified as a result of the bid for “Devolution Gloucestershire” (Exam 131). The ongoing conversation with ministers has indicated that further publically owned land may be made available in Gloucestershire through the devolution process. It is not possible to quantify this source of supply or include it within the trajectory at this stage, particularly as it does not currently satisfy the deliverability criteria required by the NPPF. The Government is expected to make an announcement regarding the release of public sector land in January 2016 and an update to the implications for land supply in the JCS area will be made available to the examination during the hearing. 3.5 Figures 3 to 8 show illustrative trajectories for the JCS as a whole, the strategic allocations and the individual districts. In response to the concerns expressed by the Inspector over the availability of a sufficient development pool within the urban extensions to meet Duty to Co-Operate (DTC) contributions over the plan period a further summary table has been prepared, shown in Figure 5. Figure 5 brings together in one table the urban extension development pool available and the amount of contribution anticipated to be needed by each authority over the plan period. These trajectories and tables are illustrative and are intended to show the how the “development pool” approach to the DTC could operate based on the land supply position as at 31st March 2015. The actual DTC contributions required by each authority will need to be responsive to delivery over the plan period to ensure each authority is able to maintain a five year housing land supply. A full explanation of the apportionment of development is set out in the document “JCS Note Strategic Allocation Apportionment” of 1st September 2015 (Exam 109).

Positive figures indicate that the authority will receive a contribution from the development pool in excess of development within the district boundary. 4.0 Development Expected in Each Area The JCS has previously made use of sub areas to identify the likely distribution of windfall development. The sub areas are identified in Figure 9. The table shown in Figure 10 uses the sub areas to provide an indication of the distribution of residential development anticipated over the plan period. This information updates the distribution shown in Exam 112 in conformity with the published annual monitoring reports and provides some commentary on development concentrations.

Major development forming an urban extension within Gloucester City at Kingsway (former RAF Quedgely). Canal side, St. Oswalds and City Centre regenerations schemes. Greenfield expansion to the city allows a mixed housing market to be maintained in the earlier stages of the plan period ahead of Green Belt release. Excellent record of delivery in this location likely to be sustained. A number of higher density schemes in this central area are supported by the City Plan and ensure a mixed housing market is maintained. Local Plan Allocation at the former Brockworth Airfield (Coopers Edge) and North Brockworth Allocation Brownfield opportunities to the east of Gloucester at Brockworth have delivered well over recent years. This is an active market that is likely to be able to sustain this level of development. Longford development together with adjacent allocations at Innsworth and North and South of Churchdown. Development in this area is currently led by development at Longford, which has delivered well over the past year. The Innsworth portion of this development is likely to be more attractive to the market as it becomes the new urban/rural transition zone. Development at Churchdown is likely to take place in the mid to latter stages of the plan period and the attractiveness of this area is likely to be able to support this level of development.

The very strong housing market in the area is likely to sustain this level of development. Development at this location is supported by the HCA at MoD Ashchurch has been awarded Housing Zone status to expedite delivery of the site. This is the only major development site proposed to deliver outside of urban extensions during the latter part of the plan period and is likely to be well received as an alternative to the urban markets. Delivery in this area is particularly strong and is led by the Homelands developments currently under construction. A further considerable consent at Cleevelands may slow delivery at Homelands into the middle of the plan period but the market could sustain these substantial extensions to Bishop’s Cleeve. 5.0 Updated Five Year Supply Calculations Three five year supply calculations for the JCS and for each authority under two scenarios are provided below for the period 2017/18 to 2021/22. The first calculation assumes 100% implementation of all permissions. The second and third calculations show a 97% and 90% implementation rate respectively. The implementation rate has been applied to all consented development where construction has not commenced. 5.1 The first scenario shown in Figure 11 applies the NPPF buffer to the housing requirement only. The second scenario shown in Figure 12 applies the NPPF buffer to the housing requirement and any shortfall anticipated in meeting the housing requirement prior to 2017/18. A composite of 5% buffer for CBC and GCC and 20% for TBC was agreed as an appropriate amalgamation of the land supply positions for each authority during the Stage 1 hearings and these figures have been used in the calculations.
