Summary AI

The appeal for up to 50 dwellings at Land Between Aspen Drive and Boscoppa Road, St Austell, Cornwall was allowed due to the need to boost the supply of homes. The proposal would result in the loss of best and most versatile land and have an adverse visual impact, but these harms were deemed to be localised and outweighed by the benefits of the development.

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Site visit made on 12 November 2024 by Alison Fish BA (Hons) DipTP MRTPI an Inspector appointed by the Secretary of State Decision date: 29 January 2025 Appeal Ref: APP/D0840/W/23/3332730 Land Between Aspen Drive and Boscoppa Road, Aspen Drive, St Austell, Cornwall PL25 3JY • The appeal is made under section 78 of the Town and Country Planning Act 1990 (as amended) against a refusal to grant outline planning permission. • The appeal is made by Ms Ruth Allen against the decision of Cornwall Council. • The application Ref is PA22/09153. • The development proposed is described on the application form as ‘proposed development of site to create fifty dwellings. A mix of open market and affordable homes’. Decision 1. The appeal is allowed and planning permission is granted for proposed development of site to create up to fifty dwellings. A mix of open market and affordable homes at Land Between Aspen Drive and Boscoppa Road, Aspen Drive, St Austell, Cornwall PL25 3JY in accordance with the terms of the application, Ref PA22/09153, and the plans submitted with it, subject to the conditions in the attached Schedule. Preliminary Matters 2.

Page 1 · Chunk 1 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision I have used the site address as it appears on the Council’s decision notice and the appeal form as the one on the planning application form was incomplete. 3. The planning application form indicates that the proposal was submitted in outline with all matters reserved for future consideration. I have assessed the proposal on this basis and treated the drawings, other than the submitted site location plan and block plan, as indicative only. 4. At the time the Council determined the planning application, a planning obligation to secure the on-site provision of affordable housing and open space and off-site financial contributions towards education infrastructure, public open space, transport infrastructure and health care provision was not before them. However, a signed Unilateral Undertaking (the UU) under section 106 of the Town and Country Planning Act 1990 was submitted during the appeal. I return to this later. 5. On 12 December 2024 a revised National Planning Policy Framework (the Framework) was published. The main parties have been given the opportunity to make comments on the implications of the updated Framework for this appeal and I have taken the comments into account in my considerations.

The main issues in this appeal are: • The effect of the proposed development on the character and appearance of the area; • Whether the proposal would result in the loss of best and most versatile land (BMV); and • Whether the proposal would deliver social and community infrastructure including affordable housing. Reasons Character and Appearance 7. The appeal site consists of an area of undeveloped land adjacent to the A391. Between the road (which is located in a cutting) and the appeal site, is a substantial belt of trees protected by a Tree Preservation Order. The appeal site is enclosed on its remaining three sides by housing. The natural appearance of the appeal site gives it a distinctive character in an otherwise built-up location. 8. The St Austell Strategy Map1 in the Cornwall Site Allocations Development Plan Document, adopted November 2019 (the DPD), identifies the appeal site as being within a ‘green buffer’. Paragraph 9.69 of the DPD identifies that the green buffer represents a logical boundary to the town, is an important biodiversity buffer and that parts offer amenity value to residents.

Page 2 · Chunk 4 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision That said, there is no policy within the DPD relating to the ‘green buffer’. The Council have instead referred me to Policy 25 of the Cornwall Local Plan Strategic Policies 2010-2030 (LP) which seeks to protect and enhance green infrastructure which is important to recreation, leisure, community use, townscape and landscape quality and visual amenity. 9. There is no public access to the appeal site which diminishes its importance to recreation, leisure or community uses. However, as an undeveloped piece of land it has some visual amenity and landscape quality, not least to local residents. 10. The DPD indicates that the A391 represents a logical boundary to the town. This results in a clear differentiation between the urban land of St Austell on one side of the road and the rolling landscape of the countryside beyond. The presence of existing urban development on three sides of the appeal site together with the influence of the A391 along the remaining boundary, means that the site is located within a part of the landscape which is characteristically urban. It therefore contributes little to the wider landscape setting of St Austell.

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision For these reasons, together with the presence of the substantial tree belt on the boundary, development of the site would have no more than a negligible effect on landscape character overall. 11. However, the containment of the site by existing residential development means that the appeal site is important to visual amenity and Policy 25 of the LP requires that it is protected accordingly. The development of the appeal site would adversely impact the visual amenity of those adjacent occupiers. The 1 Figure STA1 https://www.gov.uk/planning-inspectorate 2

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/23/3332730 appellant’s Landscape and Visual Impact Appraisal acknowledges that this would result in a moderate/substantial adverse effect for those occupiers located closest to the appeal site with a negligible visual impact from further away. Consequently, there would be moderate and somewhat localised harm to the character and appearance of the area. I therefore find that the appeal proposal would conflict with Policies 2, 12, 23 and 25 of the LP which, amongst other things, seek to respect and enhance quality of place, protect Cornwall’s natural environment and protect green infrastructure which is important to visual amenity. BMV Land 12. Whilst there is no dispute between the main parties that the appeal site is located on Grade 3 agricultural land, in the absence of a site-specific assessment I cannot be sure whether it is Grade 3a or 3b. I have therefore taken a precautionary approach and consider that the appeal proposal would result in the loss of Grade 3a BMV land. 13. The 3.31 hectare field has been split from the main farm at Boscoppa by the construction of the A391 adjacent to the appeal site.

Page 3 · Chunk 8 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision However, access has been maintained by the construction of a bridge over the A391 for vehicular traffic. Evidence from the former tenant of the land indicates that access to the field was difficult due to congestion along the approach roads and parked cars, that vandalism, theft and damage to crops was a problem and that the stoney soil meant it was not the most productive. That said, they were the tenant for twelve years and evidence from interested parties indicate that the land was farmed with the help of machinery until fairly recently. 14. On the basis of the evidence before me, I conclude that the appeal proposal would result in the loss of BMV land contrary to Policy 21 of the LP which acknowledges the economic and other benefits of BMV land such as local resilience and food security. Infrastructure Provision 15. Regulation 122 of the CIL Regulations2 requires that if planning obligations are to be taken into account in the grant of planning permission, those obligations must be necessary, directly related, and fairly and reasonably related in scale and kind to the development in question. 16.

Page 3 · Chunk 9 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Turning to the provision of affordable housing, Policy 8 of the LP requires that in St Austell, residential schemes should provide 25% affordable housing. I am therefore satisfied that the requirement for 12 affordable dwellings referred to as the ‘default affordable housing mix’ in Annex 1 of the UU would be a 25% provision and would be necessary to ensure compliance with the development plan. However, Annex 1 also contains a ‘target affordable housing mix’, being a 40% affordable housing provision offered by the appellant. Whilst additional provision is undoubtedly a good thing, particularly given the high level of housing need in the Parish, the additional provision is not necessary to make the development acceptable in planning terms and cannot constitute a reason for granting planning permission. As such, I have not attached additional weight in favour of the proposal for provision beyond the policy requirement. 2 Community Infrastructure Levy (CIL) Regulations 2010 https://www.gov.uk/planning-inspectorate 3

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/23/3332730 17. In addition to affordable housing, the UU secures the on-site provision of open space and implementation of a Travel Plan together with financial contributions to mitigate the effect of the development on recreation facilities, health and education provision, and to facilitate the implementation of the St Austell Transport Strategy. This would enable the scheme to comply with Policies 27 and 28 of the CLP and the Council’s second reason for refusal is addressed. The UU is therefore in compliance with the CIL Regulations and, with the exception of the 40% provision of affordable housing as referred to above, I can take it into account in my decision. Other Matters 18. The appellant’s submissions include a Transport Statement which indicates that the existing highway network would satisfactorily accommodate the additional traffic arising from the proposed development, and that an unacceptable impact on highway safety would not occur. The Council’s Highways Officer has raised no objection. Accordingly, on the evidence before me I am satisfied that the need for additional traffic calming measures would not arise and the safety of school children would not be compromised. 19.

Page 4 · Chunk 11 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Concerns relating to the living conditions of existing occupiers arising from overlooking, loss of privacy and crime would be addressed through the subsequent reserved matters applications relating to layout. Securing a Construction and Environmental Management Plan by a condition would address concerns relating to noise and dust during construction. 20. The appellant’s submissions include a Preliminary Ecological Appraisal3 and an Arboricultural Survey. These identify that the proposed development would result in a loss of habitat and require the removal of two trees to provide vehicular access. However, conditions securing a Biodiversity Net Gain and Management Plan, Construction Ecological Management Plan and a Landscape and Ecological Management Plan, which would include proposals for the removal of invasive species, would ensure measurable net gains to biodiversity were achieved to comply with Policy 23 of the LP. A further condition would be necessary to ensure that measures were put in place for the duration of the development to protect the existing trees along the eastern boundary of the appeal site in the interests of visual amenity. 21.

Page 4 · Chunk 12 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Concerns relating to the stability of land arising from previous mine workings could be addressed by a condition. The Statutory Undertaker has confirmed that there is capacity in the public sewer for foul drainage from the development and a scheme to deal with surface and foul water disposal could be secured by condition which would include opening up an existing culvert which runs through the site. This would prevent an increased risk of flooding and comply with the requirements of Policy 26 of the LP. Planning Balance 22. Section 38 (6) of the Planning and Compulsory Purchase Act 2004 requires that the determination of a planning application must be made in accordance with the development plan unless material considerations indicate otherwise. The Framework is a material consideration in planning decisions. 3 Both undertaken by Ecological Surveys Ltd and dated September 2022 https://www.gov.uk/planning-inspectorate 4

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/23/3332730 23. The Council have indicated that since the publication of the revised Framework in December 2024, they are no longer able to demonstrate a 5 year housing land supply. The extent of the shortfall is calculated by the Council to be circa 3.8 years. Accordingly, Paragraph 11. d) of the Framework is engaged and the policies which are most important for determining the appeal are deemed out of date. 24. Paragraph 187 of the Framework seeks to protect and enhance valued landscapes in a manner commensurate with their statutory status or identified quality in the development plan and recognise the benefits of BMV land. I have found that development of the site, identified as a green buffer would have an adverse visual impact and would result in the loss of BMV land. This weighs against the proposal. However, the weight I attribute to these harms is tempered by their localised nature and the size and functional constraints of this particular BMV land.

Page 5 · Chunk 14 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Whilst on its own, this is an argument that could be repeated for any single parcel of BMV land, the circumstances in this particular instance relate to a single field, constrained by development around its boundaries and which has become physically separated from any other agricultural land by the construction of a major road. 25. I have identified that no harm would arise in terms of the impact on biodiversity, highway safety and the living conditions of neighbouring occupiers and that the effects on community facilities could be mitigated by financial contributions. These are all neutral factors arising from my consideration of this appeal. 26. Weighed against the harm I have identified is the need to significantly boost the supply of homes. The appeal proposal is for up to 50 dwellings and this would go some way towards boosting the supply of housing (including the provision of affordable homes) at a time when the current supply position is well below Government expectations. There would also be economic benefits arising from the construction and occupation of the dwellings. I have given these benefits significant weight. 27.

Page 5 · Chunk 15 Appeal Decision

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision In conclusion, the adverse impacts of the appeal scheme would not significantly and demonstrably outweigh the benefits when assessed against the policies in the Framework taken as a whole. Accordingly on this occasion other considerations indicate that the decision should be taken otherwise than in accordance with the development plan. Conditions 28. I have had regard to the advice in the Planning Practice Guidance and the conditions set out in the Council’s committee report, together with the additional condition in the Council’s appeal statement. The appellant has had sight of those conditions and has not indicated that I should not impose them. I have undertaken some minor editing of those conditions in the interests of precision and clarity without changing their overall substance. 29. In addition to those conditions I have already referred to above and to the standard time limit conditions, a condition requiring that the development is carried out in accordance with the approved plans is necessary in the interests of certainty. https://www.gov.uk/planning-inspectorate 5

Land Between Aspen Drive And Boscoppa Road, Aspen Drive, St Austell, Cornwall, PL25 3SY — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/23/3332730 30. A Construction Environmental Management Plan is necessary to protect the living conditions of nearby occupiers and in the interests of maintaining a safe and efficient highway network but the routing of vehicles along a public highway cannot be secured by condition. A condition securing a scheme of archaeological recording is necessary to ensure the proposed development does not have a detrimental impact upon the historic environment. Conditions to deal with contamination are necessary in the interests of public safety. Conclusion 31. The proposed development would not adhere to the development plan but material considerations, namely the Framework, indicate that the appeal should be determined otherwise than in accordance with the development plan. Accordingly, the appeal should succeed.
