Summary of evidence
Policy context
National Park (Scotland) Act 2000
The National Park has four distinct aims as set out in The National Parks (Scotland) Act 2000):
- To conserve and enhance the natural and cultural heritage of the area.
- To promote sustainable use of the natural resources of the area.
- To promote understanding and enjoyment (including enjoyment in the form of recreation) of the special qualities of the area by the public.
- To promote sustainable economic and social development of the area’s communities.
These aims are to be pursued collectively. However, if there is conflict between the first aim and any of the others, greater weight is given to the first aim (as set out in Section 9(6) of the 2000 Act). This helps ensure conservation of the natural and cultural heritage underpins the economic, social and recreation value of the Cairngorms National Park. This approach is embedded in the National Park Partnership Plan and all other decision-making tools, including the Local Development Plan, adopted by the Park Authority.
The Deliverability of Site Allocations in Local Development Plans 2020
Published in February 2020 by the Scottish Government, the document summarises a survey of the 32 Scottish local planning authorities and two national parks. It explores the types of information provided by site promoters to demonstrate a development site’s deliverability and how that information is used by planning authorities. The research and report was prepared by Ryden LLP, with assistance from Neil Collar of Brodies LLP.
It concludes that the focus of site assessment, at that time, was on the initial deliverability of development land through assessment of constraints, and not upon the subsequent deliverability of development.
It identified ‘a major and consistent gap’ between site assessment information requirements and the information typically provided by site promoters. It noted that information on physical constraints is ‘usually’ or ‘seldom’ provided, and market information ‘seldom’. It found that small towns and rural planning authorities receive less applicant information on site constraints than other authorities.
It found that site assessments by planning authorities share similar criteria, but the sieve order and weighting – by market factors, physical capacity/constraints, or spatial plan priorities – are not consistent, and could potentially influence the short-listing and thus the allocation of sites. In addition, it noted that weaker market areas can end up with a very limited choice of sites, so that the “best promoted” sites are favoured.
The report advises that the concept of viability within deliverability is valid, but its application must be treated with caution. It highlights that many market sectors and locations in Scotland will struggle to fully fund all land assembly, site works, infrastructure, policy requirements and development on a ‘day one’ assessment and that seeking funding solutions and value engineering during and post-allocation are normal activities.
It advises that the site allocation process should embed market realities but should not inadvertently place these ahead of spatial planning considerations. It advises that this will be particularly important as action / delivery programmes are bound more tightly into the process of land releases.
The research proposes a proportionate framework for assessing the deliverability of site allocations. It seeks to improve confidence in deliverability across different site types, uses, geographies, and through the planning system from local development plan allocation onwards.
It proposes a staged-and-scaled site assessment which applies as a site progresses through the planning system and is proportionate to different sites. This is illustrated in Table 2.
Table 2 Staged-and-scaled sites assessment (Figure 1 of the deliverability of site allocations in local development plans report). Note that the ‘future approach’ identified in this diagram differs from the approach set out Scottish Government’s Local Development Planning Guidance and The Town and Country Planning (Development Planning) (Scotland) Regulations 2023.
Current approach: Calls for Sites → Main Issues Report → Proposed Plan → Local Development Plan
Future approach: Call for Sites and spatial plan → Gatecheck → Local Development Plan
| Stage 1 | Stage 1 information | Stages 1 and 2 information |
|---|---|---|
![]() | ||
| Local, small, early, rural, passive / patient sites | Major sites | Strategic sites: high impact, complex delivery |
The first stage is intended to provide sufficient information to conduct a sieve of sites, including sites submitted through a call for sites, existing allocations and unbuilt sites with planning permission. It would include site information, land use proposals, descriptions and distances to facilities as well as an initial indication of issues relating to natural heritage and the environment, historic environment or other potential constraints. This first sieve would also be subject to a spatial planning approach to determine whether the site would be in broad accordance with the emerging local development plan.
The report highlights that deferring or demoting spatial planning considerations during the site allocation process risks skewing development planning towards a more market-led process, however it does recognise that viability and funding are the lynchpin of deliverability, when the site is acceptable in broad policy terms, and therefore stage 1 should consider whether there is:
- A willing landowner.
- A willing developer or a note of market potential.
- Awareness of policy requirements and the infrastructure context.
- Confirmation that, in these contexts, the site is believed to be viable (or if not that there is a potential deficit funding solution).
Stage 1 will yield three types of outcomes:
- Sites not suitable for development plan allocation.
- Sites suitable for allocation without further information being sought. In the interest of transparency and best information there may some minor further dialogue with promoters or other organisations. These sites could proceed straight to proposed allocation.
- Sites where further information is required via a Stage 2 assessment.
Stage 2 is intended for major sites (greater than 50 houses / 2 hectares) which are being promoted for development plan allocation. While stage 1 seeks information and land promoter awareness of factors affecting deliverability, stage 2 seeks evidence. This is likely to include requirements for layout plans, development mix and phasing, community engagement and site conditions. Evidence of development viability and target markets would be required for housing uses and target markets for employment and commercial uses.
The report also suggests a stage 3 site assessment for very large strategic sites, which, it advises, demands a much higher hurdle than local or major sites.
The report recommends that data is captured via spreadsheets that include some functionality, for instance with hyperlinks to policies, maps and infrastructure information and forms with minimal open-ended questions and free text (where possible yes / no fields or numerical answers).
Note that this research, and its recommendations, were produced prior to the adoption of National Planning Framework 4.
National Planning Framework 4
National Planning Framework 4 came into force in February 2023 and is the long-term National Spatial Strategy for Scotland. For the first time it contains a set of planning policies that form part of the statutory development plan.
Scotland’s national spatial strategy is divided into three parts which are sustainable places, liveable places and productive places, each with two spatial principles, national developments and policies. This overarching, integrated strategy should form the basis of the local development plan’s site selection and assessment methodology and is therefore set in Table 3.
Table 3 National Planning Framework 4 – National spatial strategy, spatial principles and what it means for sustainable, liveable and productive places
| Sustainable places |
|---|
| National spatial strategy |
| ‘Scotland’s future places will be net zero, nature-positive places that are designed to reduce emissions and adapt to the impacts of climate change, whilst protecting, recovering and restoring our environment.’ |
| Spatial principles |
| * Just transition – empowering people to shape their places and ensure the transition to net zero is fair and inclusive. |
| * Conserving and recycling assets – making productive use of existing buildings, places, infrastructure and services, locking in carbon, minimising waste, and building a circular economy. |
| What it means for site selection and assessment |
| * Ensuring the right development happens in the right place. |
| * Development that is accessible by sustainable travel. |
| * Using land wisely including through a renewed focus on reusing vacant and derelict land to help limit the new land that we build on. |
| * Protecting and enhancing our historic environment. |
| Liveable places |
|---|
| National spatial strategy |
| ‘Scotland’s future places will have homes and neighbourhoods that are healthier, affordable and vibrant places to live.’ |
| Spatial principles |
| * Local living — supporting local liveability and improve community health and wellbeing by ensuring people can easily access services, greenspace, learning, work and leisure locally. |
| * Compact urban growth – limiting urban expansion so we can optimise the use of land to provide services and resources, including carbon storage, flood risk management, blue and green infrastructure and biodiversity. |
| What it means for site selection and assessment |
- Creating communities that are inclusive, empowered, resilient, safe and provide opportunities for learning – local living shaped by local context.
- Homes served by local facilities and services – enough land in the right locations to meet future needs and aspirations.
- Higher density development to sustain public transport and support local living.
- Virtual connectivity and investment in active travel links.
- Green infrastructure to connect people with nature.
| Productive places |
|---|
| National spatial strategy |
| ‘Our future places will attract new investment, build business confidence, stimulate GDP (Gross Domestic Product), export growth and entrepreneurship, and facilitate future ways of working.’ |
| Spatial principles |
| * Rebalanced development – targeting development to create opportunities for communities and investment in areas of past decline and managing development sustainably in areas of high demand. |
| * Rural revitalisation. Encouraging sustainable development in rural areas, recognising the need to grow and support urban and rural communities together. |
| What it means for site selection and assessment |
| * Diversification of town and commercial centres. |
| * Distributing development, investment and infrastructure strategically by enabling rural development. |
Relevant National Planning Framework 4 policies
Policy 1 Tackling the climate and nature crisis requires significant weight to be given to the global climate and nature crises in the consideration of all development proposals. This includes by ensuring that the local development plan’s spatial strategy will reduce emissions and adapt to current and future risks of climate change by promoting nature recovery and restoration in the area. Site allocations will be a key part of the spatial strategy¹.
¹ Matters relating to Policy 1 are covered in a range of evidence papers, including:
- Climate change: https://cairngormsldp.commonplace.is/en-GB/proposals/v3/climate-change?step=step1
- Natural heritage: https://cairngormsldp.commonplace.is/en-GB/proposals/natural-heritage-survey
This is re-enforced by Policy 2 Climate mitigation and adaptation which requires local development plans to guide development to, and create, sustainable locations based on the six spatial principles, informed by an understanding of the proposals on greenhouse gas emissions².
Within the context of Policies 1 and 2, the key policies relating to site selection and assessment are Policy 16 Quality Homes and Policy 26 Business and industry.
Policy 16 advises that deliverable land should be allocated to meet the 10-year Local Housing Land Requirement in locations that create quality places for people to live. The location of new home allocations should be consistent with local living including, where relevant, 20-minute neighbourhoods and an infrastructure first approach³.
Policy 26 requires local development plans to allocate sufficient land for business and industry, in particular ensuring that there is a suitable range of sites that meet current market demand, location, size and quality in terms of accessibility and services. The allocations should take account of local economic strategies and support objectives of delivering a low carbon and net zero economic recovery, and a fairer and more inclusive wellbeing economy⁴.
The following policies place requirements on the local development plan, which will be important considerations for site selection and assessment.
Policy 4 Natural Places requires local development plans to protect locally, regionally, nationally and internationally important natural assets. When allocating land, the spatial strategy should safeguard them and consider the objectives and level of their protected status⁵.
Policy 5 Soils, requires local development plans to protect locally, regionally, nationally and internationally valued soils. This means limiting development on prime agricultural land (or land of lesser quality that is culturally or locally important for primary use), peatland, carbon-rich soils and priority peatland habitat to a series of exceptions (and subject to the more detailed policy wording) relating to essential infrastructure only where there is a specific locational need; small-scale development directly linked to a rural business, farm or croft; production and processing facilities associated with the land; the generation of energy from renewable sources or the extraction of minerals.
Policy 9 Brownfield, vacant and derelict land and empty buildings, aims to maximise the use of existing land and buildings and minimise additional land take. Policy 9(b) states that proposals on greenfield sites will not be supported unless the site has been allocated for development or the proposal is explicitly supported by policies in the local development plan. The site selection and assessment methodology therefore need to carefully consider and justify any proposals for greenfield development in the context of brownfield land availability⁶.
Policy 12 Zero waste requires local development plans to identify appropriate locations for new waste management infrastructure to support the circular economy and meet identified needs⁷.
Policy 13 Sustainable transport requires local development plans to prioritise locations for future development that can be accessed by sustainable modes. It also requires best use to be made of existing infrastructure and services. This means allocating land well served by existing or committed infrastructure in line with National Transport Strategy 2⁸.
Policy 14 Design, quality and place requires local development plans to be place-based and created in line with the place principle⁹.
Policy 15 Local living and 20-minute neighbourhoods requires local development plans to support local living through the spatial strategy, including, within settlements, 20-minute neighbourhoods. The preparation of the spatial strategy and identification of land allocations should support local living and 20-minute neighbourhoods.¹⁰
Policy 18 Infrastructure first requires local development plans to be based on an integrated infrastructure first approach. The site selection and assessment methodology therefore need to consider infrastructure capacity¹¹.

Policy 19 Heat and cooling requires the spatial strategy to consider areas of heat network potential¹².
Policy 22 Flood risk and water management requires local development plans to avoid development in areas at flood risk as a first principle. This should be supported by managing the need to bring previously used sites in built up areas into positive use¹³.
Policy 27 City, town, local and commercial centres requires local development plans to provide a proportion of their local housing land requirement in city or town centres and be proactive in identifying opportunities to support residential development.
Policy 28 Retail advises that when local development plans are allocating sites for housing, that they consider the need for further retail provision to both meet the need for neighbourhood shopping and to support local living¹⁴.

Local development planning guidance 2023
The guidance sets out the Scottish Ministers’ expectations for new style local development plans. It advises that it should be considered together with National Planning Framework 4 and relevant legislation to give a full understanding of all requirements and expectations for local development plans. It replaces and repeals Scottish Government Planning Circular 6/2013 and the guidance states that it should be given the same weight as the repealed circular.
It is intended to assist and support planning authorities and others with an interest, rather than creating requirements in addition to those in legislation.
Planning authorities are expected to consider how the guidance can be applied in a proportionate and place-based way and to use their discretion in deciding which components of the advice are relevant to their plan preparation.
In relation to site selection, the guidance highlights National Planning Framework 4’s infrastructure first approach and advises that, in preparing local development plans, infrastructure considerations should inform site selection and the evolution of the spatial strategy, not be a by-product of it (paragraph 41).
The guidance (figure 5, page 18) sets out the key stages and assessments of the local development plan process. The Cairngorms National Park is currently within the first stage, evidence gathering, where the focus is on establishing the evidence baseline through collation of evidence and seeking the views of key agencies, children and young people, and the public at large. Following the gate check, plan preparation commences. This includes preparing a spatial strategy, early engagement, for instance through a ‘Call for Ideas’, and site assessment.
Paragraph 108 advises that ‘detailed policies and site proposals should not be included in the evidence report. Detailed site appraisal will not be appropriate at the evidence report stage, but the authority could usefully establish a site appraisal methodology that will be used to appraise sites and inform allocations for the proposed plan. This could also be linked or ideally integrated with the approach to Strategic Environmental Assessment’.
Paragraphs 141 – 190 provide a step-by-step guide to preparing proposed plans and advice on taking account of National Planning Framework 4 policies. While preparing the proposed plan is the next stage, following the approval of the evidence report, the guidance provides helpful guidance on how to establish a site appraisal methodology.
Paragraph 152 advises that all sites should be assessed using the site appraisal methodology agreed in the evidence report. This includes sites allocated in an existing local development plan; sites proposed through any call for ideas and any other sites the planning authority considers may have potential.
Paragraph 153 advises that the site appraisal process and the Strategic Environmental Assessment requirements can be helpfully linked as they cover similar environmental topics. It also notes that all ‘potential’ sites should be covered by the Strategic Environmental Assessment, so that if, at examination, it is considered that additional sites need to be identified, these have already been assessed.
Paragraph 154 advises that no site should automatically roll forward from one plan to the next without being assessed. All sites proposed to be allocated for development in plans should have been assessed for their deliverability through the site appraisal process.
The document provides guidance on relevant parts of the national planning framework 4 in relation to each stage of local development plan preparation. In relation to Policy 16 Quality homes, it confirms that the location of homes should be in line with the plan’s spatial strategy and informed by engagement with public, private and community interests. It advises that use of the Place Standard, consideration of local place plans and guidance on local living and 20 minute neighbourhoods can inform allocation choices.
In relation to Policy 26 Business and Industry, the guidance advises that all sites under consideration for allocation should be assessed for their ability to meet current needs and market expectations and that flexibility and resilience for business and industry should be built into site allocations. It advises that where existing business sites are underused, for example where there has been an increase in vacancy rates, reallocation to enable a wider range of viable businesses or alternative uses may be considered, taking careful account of the potential impacts on existing businesses on the site.
It also advises that ‘local development plans should encourage, including by use of the spatial strategy and site allocations, opportunities for home-working, live-work units, micro-businesses and community hubs. In the past industrial and business areas have tended to be located at a distance from residential areas. As our economy continues to evolve, there may be scope for greater integration of work and living as inter-related land uses which will also support our ambition for net zero. This can help to tackle inequalities by providing more accessible, local job opportunities which reduce the need to travel’.
In relation to Strategic Environmental Assessment, paragraph 184 recognises that, if a planning authority undertakes a call for ideas stage, any site may be submitted. It advises that ‘it is legitimate for the authority to assess each site through the broad principles of the spatial strategy prepared as part of the work on the proposed plan’.
Paragraph 185 continues on this theme, advising that the place-based approach to plans (e.g. on a settlement / neighbourhood basis), ‘allows the opportunity to reflect the broad environmental impacts and benefits of the policies and proposals rather than impacts of individual sites, which can support proportionality in terms of reporting and potentially a more engaging report as a consequence’.
The Joint Local Development Plan Site Assessment and Strategic Environment Assessment Checklist produced by the Government Key Agencies (February 2024)
The Scottish government key agencies group distributed their assessment checklist in February 2024. The Key Agencies are: Scottish Natural Heritage; Scottish Environment Protection Agency; Historic Environment Scotland; Transport Scotland; Scottish Water; and Architecture and Design Scotland. The document covers the topics:
- Water
- Biodiversity, flora and fauna
- Climate factors
- Air quality
- Population and human health
- Soils
- Landscape
- Cultural heritage
- Material assets – deliverability / sustainability constraints.
These broadly follow the issues, listed in Schedule 3 paragraph 6(a) of the Environmental Assessment (Scotland) Act 2005, on which development proposals (referred to as plans or programmes in the Act) are likely to have ‘significant effects on the environment’.
It asks open-ended questions, linking these back to National Planning Framework 4 policies. It requires scoring pre-mitigation, then details of mitigation and enhancement before requiring a second post-mitigation score, with a final column for comments / conclusions.
It highlights that there are many scoring techniques and gives the example of a coloured significantly positive (++) to significantly negative ( — ) system. It also includes an explanation of the key Strategic Environmental Assessment topics.
Guidance on Key Agency engagement with local development plan site appraisals (March 2025)
This guidance sets out high level principles aimed at getting the best out of the key agencies in supporting the site appraisal process. The principles facilitate timely and effective responses that add most value to the local development plan preparation process and ultimately support the smooth delivery of sites. They are framed around where and how key agencies are best involved in the process.
To maximise value from the key agencies, the guidance states that following the initial sifting process key agencies should be consulted on sites that:
- Are preferred or a reasonable alternative and align with your spatial strategy and associated infrastructure first approach; and,
- Relate to issues or opportunities that fall within the remit of the relevant key agency where further bespoke advice is required to support delivery. Some agencies may want to review all the preferred and alternative sites due to potential cumulative effects and will advise the planning authority accordingly.
It is not required to consult the key agencies on all sites that are proposed for development.
The key agencies request that sites submitted to them should be:
- Supported by a summary of the reason for requesting key agency input.
- Grouped in one batch — repeated individual requests undermine the advice provided and may not enable agencies to provide robust advice on cumulative impacts.
- Supplied with a GIS shapefile.
- Accompanied by the initial site assessment findings (and indicative or draft SEA site assessment findings for Consultation Authorities).
- Presented in an easy to understand and clear format, for example, preferred / alternative sites and different site use classes could be colour coded and/or clearly categorised.
A minimum consultation period of six weeks is requested, however more time may be required depending on the number and complexity of the sites involved.
The Park Authority will follow the key agencies’ guidance when engaging them on sites.
Scottish Environment Protection Agency Planning Advice Note for Planning Authorities: Scottish Environment Protection Agency engagement in local development plan site appraisal and assessment (May 2025)
The guidance aligns with the key agency guidance that the Park Authority will follow in engaging with the key agencies. The Scottish Environment Protection Agency advice note also outlines specific evidence related to their area of interest that should be used for the initial stages of the site appraisal and when Scottish Environment Protection Agency may need to be consulted later in the process.
In particular, the advice note highlights the importance of strategic flood risk assessment outputs for the site assessment process. The Park Authority has prepared a Strategic Flood Risk Assessment, which has been found sufficient by Scottish Environment Protection Agency:
The outputs of the strategic flood risk assessment will form part of the site assessment process. Further information on these matters are presented in the flood risk and water management topic paper:
The Park Authority will follow Scottish Environment Protection Agency’s advice note when engaging them on sites.
Strategic Environmental Assessment
Strategic Environmental Assessment is a statutory requirement that aims to ensure the environment is a primary consideration in the preparation of qualifying public plans, programmes and strategies. The Environmental Assessment (Scotland) Act 2005 requires those preparing qualifying plans, including the local development plans, to undertake a Strategic Environmental Assessment. Strategic Environmental Assessment can also benefit the preparation of a local development plan, supporting better understanding of its environmental context and setting
