Sustainability Appraisal and Habitats Regulation Assessment

I write in response to the regulation 19 consultation version of the Chichester Local Plan 20212039 on behalf of my client Obsidian Strategic.

Obsidian Strategic have an interest in a site to the South of Main Road, in Hermitage, within the Southbourne Neighbourhood Plan Area. Further details in relation to the site are set out within the appendices of these representations and referred to throughout.

Housing Requirement

The identified housing need for Chichester District Council (CDC) as calculated by the standard method is 638 dwellings per annum (dpa). However, the local plan only seeks to provide 575 dpa or a total supply of 10,350 over the plan period (2021-2039). As result the proposed strategy represents an under supply of 1,134 over the plan period. Furthermore, the undersupply means that CDC is unable to accommodate the unmet arising from the South Downs National Park.

In recent years CDC has not been able to demonstrate a five year housing land supply nor has it delivered housing against the requirements of the Housing Delivery Test. It is therefore important that the unmet need is made up within the early part of the plan period.

Paragraph 5.2 of the plan states that the under supply is due to constraints across the district particularly the capacity of the A27.

Policy H1 (Meeting Housing Needs) sets out the housing target of 10,350 dwellings to be delivered over the plan period 2021-2039. Considering the existing commitments, allocations and permissions this gives a remaining figure without planning permission of 3,056 homes for allocation in the Local Plan.
Strategic Allocations
Policy H2 of the reg 19 plan sets out the following strategic site allocations which are carried forward from the 2015 Local Plan:

**Table**

Table 11 of the latest Annual Monitoring Report (AMR) (produced in November 2022) show the progress of delivery from these allocations:

**Table**

Table 12 of the AMR sets out the progress of the large sites towards future delivery as follows:

**Table**

The Housing Trajectory as set out in Appendix E of the Local Plan shows delivery of the existing allocations as set out under policy H2. Given that the Land at Shopwyke (A7) and the Land at Westhampnett/North-East Chichester (A9) already have permission for the number of dwellings in the allocation and construction has already started, there is no objection to the predicted levels of delivery as set out in the trajectory.
However, the housing trajectory sets out delivery from the Land West of Chichester (Phase 2) (A6) and Tangmere SDL as follows:

**Table**

Given that neither of these sites have outline permission then the delivery of units from both sites in a little over 5 years from the adoption of the plan is considered wholly unachievable.

CDC has presented no evidence to justify how this timeframe would be achieved and it is considered that the trajectory is unreliable as a result.


The Local Plan sets out a Broad Location for Development at Southbourne which would be delivered through either the Neighbourhood Plan process or a Site Allocation DPD:

**Table**

The Housing Trajectory as set out in appendix E of the Local Plan sets out the following delivery from this site:

**Table**

Given that policy A13 remains as a ‘broad area for development’ it is not considered that there is adequate justification for the trajectory as set out. Notwithstanding the effectiveness of allocating a site in this way, an exact location for the housing is yet to be defined, nor is delivery through the neighbourhood plan/DPD confirmed (further details on this is set out within the reps). Until a more detailed site can be defined and delivery confirmed it is not considered that CDC is able to guarantee delivery of dwellings in the housing trajectory as it has done so within the plan.

Non-Strategic Parish Housing Requirements
Policy H3 sets out the following housing requirements from individual parishes.

**Table**

The supporting text of policy H3 sets out that if draft neighbourhood plans making provision for at least the minimum housing numbers of the relevant area have not made demonstrable progress the council will allocate sites for development within a development plan document in order to meet the requirements of this Local Plan.

Table 13 of AMR identifies that there has been historically poor delivery of net housing completions from parishes:

**Table**

The overall strategy as set out by CDC in the plan is highly dependent on the delivery of housing from Neighbourhood Plan areas. Whilst this approach is not un-sound in itself, it is considered that the plan in its current form allows for little mitigation or alternatives should delivery not come forward in the neighbourhood plan areas.

In order for the plan to be considered positively prepared and justified it is recommended that additional wording is added to policy H3 to state that individual applications can come forward on sustainable sites outside of existing settlement boundaries in parishes should delivery not come forward within the first five years of the plan period. Priority should be given to any sites already identified within draft versions of Neighbourhood Plans.

on sustainable sites outside of existing settlement boundaries in parishes should delivery not come forward within the first five years of the plan period. Priority should be given to any sites already identified within draft versions of Neighbourhood Plans.
Southbourne
As set out, the Local Plan proposes a ‘Broad Location for Development’ at Southbourne for the delivery of 1,050 dwellings. This approach follows the withdrawal of the previously draft version of Neighbourhood Plan after it was found not to comply with basis conditions following examination in early 2022. Southbourne Parish Council is now pursuing a revised Neighbourhood Plan which has been submitted to CDC for a regulation 16 consultation. Obsidian previously responded to the regulation 14 consultation in late 2022 and these are appended to these representations.
The revised Southbourne Neighbourhood Plan does not seek to allocate any new housing allocations and instead takes a protectionist stance against any new development as an interim position whilst the Local Plan is prepared. However, once the Neighbourhood Plan is made, it would form part of the development plan for CDC. It is highly likely that a made Neighbourhood Plan in the form currently proposed by Southbourne would make the allocation of additional housing in the parish less likely rather than more likely.
The Sustainability Appraisal (SA) as prepared for the regulation 19 of the Local Plan sets out the proposed approach to Southbourne as follows:
3.1. With the decision of Southbourne Parish Council to no longer proceed with the inclusion of a strategic allocation in their neighbourhood plan, the Council considered three options for taking forward development in Southbourne, namely:
• Option 1 - redistribute the housing number elsewhere
• Option 2 - allocate a strategic site
• Option 3 - identify a Broad Location for Development
The SA goes on to set out the reason for option 1, for redistributing the housing number elsewhere, being discounted as follows:
3.2. As set out in the Housing Background Paper, the preferred spatial strategy is to focus the majority of growth at Chichester and the east west corridor, with a focus on the Settlement Hubs within the corridor. To redistribute the housing number to other parts of the plan area would not be consistent with the preferred spatial strategy nor reflective of the role of Southbourne as one of the more sustainable locations in the plan area capable of delivering strategic scale development. The ability to redistribute the number to other locations within the east/west corridor is also severely limited due to infrastructure constraints (impact on A27 junctions) or environmental restrictions (wastewater treatment capacity). For these reasons, Option 1 was discounted.
Whilst it is accepted that the redistribution of the entire requirement of 1,050 homes would be problematic, it is considered that CDC should have tested the allocation of other alternative sites such as that at Main Road, Hermitage and other suitable alternative sites.
The SA goes on to set out consideration of option 2 as follows:
3.3. In order to allocate a site in a Local Plan, it needs to have gone through a rigorous process to ensure that the Council can demonstrate that the allocated site is suitable, given reasonable alternatives, and is based on proportionate evidence. Given there is more than one site or combination of sites that could come forward as an allocation in Southbourne, a clear process setting out for why one site was chosen over another would be needed, informed by site specific technical information.
This is correct and it is therefore not accepted that an approach to allocate a broad area for development would be robust, deliverable or effective. The SA goes on to state:
3.5. The allocation of a strategic site at Southbourne would also be a significant change in approach at a late stage of the Local Plan preparation process. The additional technical evidence that would need to be undertaken to justify a Local Plan allocation at this stage would impact significantly in terms of delay to the finalisation of the Regulation 19 Local Plan and its subsequent submission to the Secretary of State for examination. For these reasons Option 2 was discounted.
This provides further weight to the position set out within these representations that the expectation of delivery from the ‘broad area’ at Southbourne is overly ambitious and it is clear there is significant technical work to undertake on the delivery of homes from the allocation as part of the future plan making process.
The SA goes on to set out the justification of option 3 as follows:
3.6. The identification of a BLD is consistent with the National Planning Policy Framework (NPPF). Paragraph 68 states that for years 6 -10 of the plan, local authorities should through their planning policies identify a supply of ‘specific, developable sites or broad locations for growth’.
3.7. There is no definition of ‘broad locations’ in national policy. It is generally taken to be an area within which housebuilding could reasonably be expected to take place based on the availability of land having regard to the Housing and Economic Land Availability Assessment (HELAA). A BLD does not have a specific geographic location or physical boundary. Areas are identified as broad locations because at that stage it is not yet possible to identify the precise boundaries of a site until further detailed site work has been done. By identifying a broad location gives flexibility and may increase the prospect of appropriate and effective growth i.e. where there is some doubt as to the most effective site boundary could prevent growth coming forward or prevent the most sustainable solution. However, a broad location might be expected to accommodate a significant amount of development; in some cases a single site may be of a sufficient size to accommodate all of the potential development or a number of sites that abut other sites may be considered together.
This is not considered a rational approach to take. Whilst there is no definition of ‘broad location’ within national policy it is considered that the words ‘specific’ and ‘developable’ must be taken at their basic meaning and indeed as set out in the glossary of the framework. It is not considered that the allocation of such a large area for a ‘broad location’ would be specific, effective or justified against the tests of soundness in the NPPF.
The allocation of Southbourne under policy A13 would represent over 10% of the total housing delivery in the plan. This is considered too significant to leave to a broad location for development.
As set out, Southbourne Parish Council is already at advanced stages of a revised Neighbourhood Plan which does not include the allocation of any of the development parcel envisaged under policy A13. In terms of delivery through the Site Allocations DPD, the timetable for this is set out within the most recent Local Development Scheme (January 2023) which sets out the following:

**Table**

As set out, the housing trajectory assumes delivery of dwellings from the allocation at Southbourne in 2028/29. Given that the Site Allocation DPD would not be delivered until Winter 26/27 at the earliest, and the delivery through the Neighbourhood Plan has been discounted by the progression of a NP without the allocation, then the deliverability of any development at Southbourne remains wholly unjustified within the plan period.
The SA goes on to set out the approach to alternative sites in Southbourne Parish as follows:
4.3. The 2021 HELAA assessed 41 sites in Southbourne Parish (see Appendix 1). Of these, 18 sites were discounted because the site either had planning permission/were under construction (five sites); it was within the Chichester Harbour Area of Outstanding Natural Beauty (AONB) (eight sites); there was insurmountable access issues (two sites); it was in Flood Zone 3 (one site); or there was a legal restriction on the site use (in this case a Section 106 Agreement restricting use to open space) (two sites). These sites were not considered further for inclusion within the BLD.
The land at Main Road was one of the sites discounted due to being located in the AONB. For the reasons set out within subsequent sections of these representation, it is not considered that it was necessary to discount sites within the AONB as other councils have taken the decision to use such sites to meet housing need and not considered the AONB as an absolute constraint.
Specialist Accommodation for Older People
Para 5.41 of the regulation 19 of the Plan sets out the following:
The Housing and Economic Development Needs Assessment (HEDNA) 2022 estimates the greatest population increase in the district by 2039 to be those in age groups 75 and over. To support an ageing population there should be provision of suitable housing options for the differing needs of individuals, including:
• Sufficient adaptable and/or accessible market housing stock so that those wishing to remain in their own homes can do so as their needs change.
• Smaller homes, for those wishing to downsize, and bungalows.
• Extra care housing, for those able to live relatively independently but requiring on-site support.
• Care homes, for those needing additional support.
Table 8.1 of the HEDNA sets out the current population breakdown for separate groups over 65 and demonstrates that CDC has a significantly higher percentage in all age groups over 65 than the average in West Sussex, the South East or England:

**Table**

Policy 8.12 of the HEDNA goes on to set out the need for different groups as follows:

**Table**

The HEDNA sets out the following commentary in this regard:
8.41 It can be seen by 2039 there is an estimated need for between 2,131 and 2,872 additional dwellings with support or care across the whole study area. In addition, there is a need for 429-800 additional nursing and residential care bedspaces.
8.42 Typically for bedspaces it is conventional to convert to dwellings using a standard multiplier (1.80 bedspaces per dwelling for older persons accommodation) and this would therefore equate to around 238-445 dwellings.
8.43 In total, the older persons analysis points towards a need for around 2,369-3,317 units over the 2021-39 period (132-184 per annum) – the older person need equates to some 17-24% of all homes needing to be some form of specialist accommodation for older people.

Given the significant need for Specialist Housing Accommodation across the district it is vital that this is planned for adequately within the emerging Local Plan. The Planning Practice Guidance sets out why it is important to plan for housing needs of older people as follows:
The need to provide housing for older people is critical. People are living longer lives and the proportion of older people in the population is increasing. In mid-2016 there were 1.6 million people aged 85 and over; by mid-2041 this is projected to double to 3.2 million. Offering older people a better choice of accommodation to suit their changing needs can help them live independently for longer, feel more connected to their communities and help reduce costs to the social care and health systems. Therefore, an understanding of how the ageing population affects housing needs is something to be considered from the early stages of plan-making through to decision-taking.
Paragraph: 001 Reference ID: 63-001-20190626 Revision date: 26 June 2019
The PPG goes onto state how housing requirements of such groups should be addressed in plans:
Plan-making authorities should set clear policies to address the housing needs of groups with particular needs such as older and disabled people. These policies can set out how the planmaking authority will consider proposals for the different types of housing that these groups are likely to require. They could also provide indicative figures or a range for the number of units of specialist housing for older people needed across the plan area throughout the plan period.
Paragraph: 006 Reference ID: 63-006-20190626 Revision date: 26 June 2019
Policy H8 states:
All housing sites over 200 units, including those allocated in this plan, will be required to provide specialist accommodation for older people to include a support or care component. The specific type and amount of accommodation required will depend on the size and location of the site.

Proposals for specialist housing, such as homes for older people, student, HMOs or essential worker accommodation, and other groups requiring specifically designed accommodation will be supported where the following criteria are met:

1) There is an identified need;
2) It will not lead to a concentration of similar uses in an area that would be detrimental to the character or function of an area and / or residential amenity;

3) It is in close proximity to everyday services, connecting by safe and suitable walking / cycling routes or public transport for the intended occupier;
4) It can be demonstrated that the development is designed to provide the most appropriate types of support for the target resident;
5) It can be demonstrated that revenue funding can be secured to maintain the longterm viability of the scheme (if relevant to the type of accommodation proposed); and
6) The scheme is supported by the relevant agencies (if relevant to the accommodation type to be provided).

Proposals which may result in the loss of specialist needs accommodation will not be permitted unless it can be demonstrated that there is no longer a need for such accommodation in the plan area, or alternative provision is being made available locally through replacement or new facilities.

Whilst this approach goes some way to addressing the care needs it is felt that the policy lacks effectiveness and should take a far more constructive and positive approach to the provision of housing for older people.
The wide range of different housing typologies is set out within the Planning Practice Guidance as follows:
• Age-restricted general market housing: This type of housing is generally for people aged 55 and over and the active elderly. It may include some shared amenities such as communal gardens, but does not include support or care services.
• Retirement living or sheltered housing: This usually consists of purpose-built flats or bungalows with limited communal facilities such as a lounge, laundry room and guest room. It does not generally provide care services, but provides some support to enable residents to live independently. This can include 24 hour on-site assistance (alarm) and a warden or house manager.
• Extra care housing or housing-with-care: This usually consists of purpose-built or adapted flats or bungalows with a medium to high level of care available if required, through an onsite care agency registered through the Care Quality Commission (CQC). Residents are able to live independently with 24 hour access to support services and staff, and meals are also available. There are often extensive communal areas, such as space to socialise or a wellbeing centre. In some cases, these developments are known as retirement communities or villages - the intention is for residents to benefit from varying levels of care as time progresses.
• Residential care homes and nursing homes: These have individual rooms within a residential building and provide a high level of care meeting all activities of daily living. They do not usually include support services for independent living. This type of housing can also include dementia care homes.
[Paragraph: 010 Reference ID: 63-010-20190626].

It is considered that a residential care home (including housing for dementia needs) could be developed on the Land South of Main Road without causing harm to the AONB and this would provide for a clear need within the village whilst also providing employment to local workers.
Development in AONB
The NPPF sets out the following in relation to development in the AONB at paragraph 172 as follows:
Great weight should be given to conserving and enhancing landscape and scenic beauty in National Parks, the Broads and Areas of Outstanding Natural Beauty, which have the highest status of protection in relation to these issues. The conservation and enhancement of wildlife and cultural heritage are also important considerations in these areas, and should be given great weight in National Parks and the Broads. The scale and extent of development within these designated areas should be limited. Planning permission should be refused for major development55 other than in exceptional circumstances, and where it can be demonstrated that the development is in the public interest. Consideration of such applications should include an assessment of:
a) the need for the development, including in terms of any national considerations, and the impact of permitting it, or refusing it, upon the local economy;
b) the cost of, and scope for, developing outside the designated area, or meeting the need for it in some other way; and
c) any detrimental effect on the environment, the landscape and recreational opportunities, and the extent to which that could be moderated
Footnote 55 of paragraph 172 is relevant for the consideration of what is considered as major development and states:
For the purposes of paragraphs 172 and 173, whether a proposal is ‘major development’ is a matter for the decision maker, taking into account its nature, scale and setting, and whether it could have a significant adverse impact on the purposes for which the area has been designated or defined.
No evidence is set out within the Local Plan or supporting evidence base to state what is considered to be a major development site in the district. Neither the Chichester Harbour AONB: State of the AONB Report (May 2018) or the Chichester Harbour AONB Landscape Character Assessment (April 2019) contain any references to what is considered to constitute a major development.
This is a matter which has been considered at length within other Local Plan examinations. As part of the evidence for its Local Plan, the South Downs National Park sought successive legal opinions from James Maurici QC on what should be considered as ‘Major Development’ in the AONB and have subsequently become widely known as the ‘Maurici Opinions’ in other Local Plan examinations. The opinions set out the following conclusions:
• It is a matter of planning judgement to be decided by the decision maker.
• Major development is to be given its ordinary meaning, and it would be wrong to apply the definition of major development contained within the Town and Country Planning (Development Management Procedure) (England) Order 2015. It would also be wrong to apply any set or rigid criteria for defining major development, and the definition should not be restricted to development proposals that raise issues of national significance.
• The decision maker may consider whether the proposed development has the potential to cause a significant adverse impact on the purposes for which the area has been designated or defined, rather than whether there will indeed be a significant adverse impact from the proposed development.
• The decision maker may consider the proposed development in its local context as a matter of planning judgement.
• There may be other considerations but which may not determine whether a proposed development is major development. For example, if the proposed development is Environmental Impact Assessment (EIA) development.
• The ordinary sense of the word ‘major’ is important and the decision maker should take a common sense view as to whether the proposed development could be considered major development.

In the Mid Sussex District Council Site Allocations DPD Evidence Base there is a topic paper setting out consideration of Major Development in the AONB and concludes that several of the allocations, in some cases up to 70 dwellings, would not be classed as major development in the AONB following a detailed review of each of the factors as set out in footnote 55 of the NPPF against each proposed allocation.
It is considered that this approach should have been undertaken for each of the individual sites discounted in the Local Plan (including Main Road, Hermitage), rather than simply discounting on the sole fact that they were in the AONB.
Sustainability Appraisal
The legal frameworks for SAs are set out within section 19 of the Planning and Compulsory Purchase Act 2004 which states that the authority must prepare a plan with the objective of contributing to the achievement of sustainable development. Moreover, the requirements of the Environmental Assessment of Plans and Programmes Regulations 2004 states that SAs must ensure that the potential environmental effects are given full consideration alongside social and economic issues.

It is not considered that the council has given full consideration to all effects nor are the conclusions of the SA in respect of those impacts robust and logical.
Paragraph 32 of the framework goes on to state that the SA should demonstrate how the plan has addressed relevant economic, social and environmental objectives (including opportunities for net gains). Significant adverse impacts on these objectives should be avoided and, wherever possible, alternative options which reduce or eliminate such impacts should be pursued. Where significant adverse impacts are unavoidable, suitable mitigation measures should be proposed (or, where this is not possible, compensatory measures should be considered).
The SA sets out whether it was reasonable to explore higher growth scenarios as follows:
5.2.12 As discussed above, the PPG on Housing and Economic Needs Assessment sets out reasons for providing for ‘above LHN’ through local plans, referring to situations where there are “growth strategies for the area... (e.g. Housing Deals); strategic infrastructure improvements that are likely to drive an increase in [need]; or an authority agreeing to take on unmet need from neighbouring authorities...” Also, affordable housing needs can serve as a reason for considering setting the housing requirement at a figure above LHN, with the PPG stating: “An increase in the total housing figures included in the plan may need to be considered where it could help deliver the required number of affordable homes.”
5.2.13 However, in the Chichester context there is little or no argument for exploring scenarios whereby the housing requirement is set at a figure above LHN, given the issues discussed above at paragraph 5.2.11. Unmet housing needs are a widespread issue across the sub-region, but there is no realistic potential to provide for unmet housing needs within Chichester. At the time of the Preferred Approach consultation (2018/19), the proposal was to provide for both locally arising housing needs in full and a proportion of the unmet needs arising from the SDNP (41 dpa). Also, it is noted that the SA report published as part of the consultation considered scenarios – considered to be ‘reasonable’ at that point in time – that would see the housing requirement set at figures significantly above LHN (800 dpa and 1,000 dpa were tested). However, at the current time, in light of the latest available evidence, scenarios involving setting the housing requirement at a figure above LHN can be safely ruled out as unreasonable.
It is not considered that a figure at or above the LHN would be considered unreasonable and that this matter has not been given full consideration (as per the requirements of the SA regulations), particularly in regard to the social impacts of not meeting housing need in full.
Appendix V of the SA sets out commentary in regard to Parish Scenarios. This sets out the following in relation to Southbourne (with emphasis added):

With regards to the extent of the broad location, this matter is considered fairly uncontentious (for the current purposes of arriving at reasonable growth scenarios). Specifically, the proposal is to identify an area of search that includes developable HELAA sites that relate relatively well to the Southbourne settlement edge and avoid the Strategic Wildlife Corridor associated with the Ham Brook, also naturally mindful of the need to maintain a landscape gap to settlements within Chidham and Hambrook Parish, to the east. It is important to note that the total theoretical capacity of developable HELAA sites within this broad area is far in excess of the number of homes that would need delivered under any reasonably foreseeable scenario.
The broad location provides flexibility to identify a detailed allocation either through a Site Allocations Plan or, should the Parish Council wish to do so, a revised Southbourne Parish Neighbourhood Plan. Site selection considerations will likely include: transport and access (including mindful of links to the train station and by car to Portsmouth); accessibility and community infrastructure (mindful of the secondary school, recreation ground and employment area at the western edge of the village); heritage (e.g. there is a historic rural lane to the east, associated with two listed buildings), topography and landscape (including any visual links to the SDNP and/or the AONB) and the potential to secure a strategic scheme that delivers more than just new market homes, and potentially significant ‘planning gain’ for the local community.
With regards to the number of homes that should be supported, there is logic to further exploring the scale of growth that was previously considered through the now withdrawn Southbourne NP, and it is not clear that there is an argument for considering lower growth. Additionally, there is a clear argument for exploring the possibility of higher growth, to ensure a suitably comprehensive scheme, with a high level of ‘planning gain’.
In conclusion, there are two scenarios for Southbourne Parish, namely completions, commitments and windfall plus either: 1) a broad location for 1,050 homes; or
2) a broad location for ~1,500 homes.
As set out, it is not considered that the SA has considered adequate reasonable alternatives to growth at Southbourne which would include allocation of sites elsewhere in the village including within the AONB that can deliver in the early part of the plan period.

Conclusions
There are significant concerns on the soundness of the plan in terms of whether it is effective, justified, positively prepared or consistent with national policy in accordance with paragraph 35 of the NPPF.

It is not considered that the Council has justified the extent of the under supply of housing against the established housing need. There are significant concerns over the delivery of housing from the strategic allocations within the unjustified timescales as set out within the trajectory contained in the plan.
The Council has not adequately considered reasonable alternatives through the Sustainability Appraisal as published alongside the plan which should have included consideration to the allocation of the site in order to deliver housing in the early part of the plan period.
The plan fails to adequately consider the need for housing for older people, given that the population over 65 across CDC is significantly in excess of the average in the county, south east and county as a whole.
CDC discounted all sites within the AONB, including the site at Main Road, Hermitage, at an early stage of the plan making process. This is not considered effective or consistent with national policy which does not class such sites as an absolute constraint. Other local authorities have allocated such sites in order to deliver the full objectively assessed needs.
ABC will continue to make further representations on the deliverability of the site as part of the plan making progress.
