Field 534635, Slegaby Lane, Hillberry, Onchan, Isle Of Man, IM4 5bn
Permission was sought to construct an agricultural storage building on Field 534635, Slegaby Lane, Hillberry, Onchan. The site is approximately 15 acres and the proposed building would sit in an isolated position around 190–220 metres from the nearest residential properties. The application was refused on two grounds. First, the size and siting of the building were considered harmful to the character and quality of the countryside, with no sufficient justification provided to override the general presumption against development outside designated zones. Second, no overriding agricultural need for the building was established, and conflicting information within the submission undermined the case for an exception. The decision was made by a Principal Planner under delegated authority, with the officer also recommending refusal.
The application was refused because there was insufficient justification to override the presumption against development in the countryside. The proposed building's size and isolated siting were judged harmful to the character and quality of the landscape. Additionally, no overriding agricultural need was demonstrated, and conflicting information was submitted in support of the proposal.
Refusal Reasons
General Policy 3(g)
presumption against development outside areas zoned for development
Environment Policy 1
protect the countryside from unwarranted development
Area Plan for the East sets out locally-applicable means for implementing the policies set out in the Isle of Man Strategic Plan 2016. In that Strategic Plan, we find the Environment Policies. Environment Policy 1 states: The countryside and its ecology will be protected for its own sake. For the purposes of this policy, the countryside comprises all land which is outside the settlements defined in Appendix 3 at A.3.6 or which is not designated for future development on an Area Plan. Development which would adversely affect the countryside will not be permitted unless there is an over- riding national need in land use planning terms which outweighs the requirement to protect these areas and for which there is no reasonable and acceptable alternative. Maintaining the purpose of this Area Plan as a means of implementation, there is some further direction to be found in the Strategic Plan, at paragraph 7.2.1: 'Whilst landscape and coastal change is inevitable, and in some cases desirable, the emphasis must be on the appropriateness of this change and the balance or equity between the needs of conservation and those of development. The primary goal must therefore be to respect, maintain and enhance the natural and cultural environment including nature conservation and landscape and coastal quality, and ensure its protection from inappropriate development.' Given the comprehensive nature of the Isle of Man Strategic Plan's Environmental Policies, only a small number of additional Proposals and Recommendations are necessary. In order to produce an implementable Area Plan for the East it is necessary to recognise those statutory desig nations and strategies which whilst having an Island-wide scope are highly relevant to the protection of environments within the Plan Area. An example is the UNESCO Biosphere status afforded to the Isle of Man. Island-level strategies identify crossborder issues and take account of the cumulative impacts of human engagement with nature. Area Plan Objectives i. To protect, conserve and enhance the natural and cultural environment of the plan area and promote biodiversity. ii. To improve the function, usability and provision of our green infrastructure and public spaces by providing a network of green spaces and features which are connected and where possible, accessible to the public. iii. To manage and improve flood risk and improve drainage conditions. iv. To support the working countryside and its custodians in maintaini ng a sustainable rural economy. Area Plan Desired Outcomes i. Where approved, d evelopment will be ecologically sustainable and designed to protect and where possible enhance biodiversity as well as mitigate and adapt to the effects of climate change. ii. The Green Infrastructure network will be established and fostered, connecting people with nature in a way that achieves the best shared outcomes for the urban and natural environment. iii. Statutory and non-statutory designations will continue to provide protection to the most important and most vulnerable cultural assets, habitats and environments in the plan area. iv. Beyond the towns and villages, the area as a whole will retain its landscape setting including its important visual interaction with the central uplands, central valley, coast and marine environment. Natural Environment Proposal 1 The Department supports the protection, creation and improvement of green infrastructure in the East, particularly in those locations which have the potential to be part of a Green Infrastructure Network. Applications for development must take into account any approved Government Green Infrastructure Strategies, but in any case, must identify how development proposals intend to contribute to the long term provision of a network of connected green spaces. UNESCO Biosphere In 2017, the Isle of Man became the first ever entire nation to achieve UNESCO Biosphere status. Project partners pledge to take steps to protect natural resources, develop the economy in a sustainable way and promote outstanding living landscapes. UNESCO Biosphere Reserves are established to connect people and the economy with nature, wildlife, culture, heritage and communities. Biosphere Reserves have three functions: Conservation: to contribute to the conservation of landscapes, ecosystems, species and genetic variation. Development: to foster economic and human development which is socio -culturally and ecologically sustainable. Logistic support: to support demonstration projects, environmental education and training, research and monitoring related to local, regional, national and global issues of conservation and sustainable development. The Isle of Man Biosphere is zoned into six areas . Examples of all of these can be found in the Eastern area: Terrestrial Core areas, Marine Core areas, Terrestrial Buffer zone, Marine Buffer zone, Terrestrial Transition areas and Marine Transition areas. There is some overlap with The Isle of Man's First Biodiversity Strategy 2015-20
General Policy 3(f)
exceptions to development in the countryside including operations essential for conduct of agriculture
Environment Policy 15
general design criteria for agricultural buildings
Environment Policy 15: Where the Department is satisfied that there is agricultural or horticultural need for a new building (including a dwelling), sufficient to outweigh the general policy against development in the countryside, and that the impact of this developme nt including buildings, accesses, servicing etc. is acceptable, such development must be sited as close as is practically possible to existing building groups and be appropriate in terms of scale, materials, colour, siting and form to ensure that all new d evelopments are sympathetic to the landscape and built environment of which they will form a part. Only in exceptional circumstances will buildings be permitted in exposed or isolated areas or close to public highways and in all such cases will be subject to appropriate landscaping. The nature and materials of construction must also be appropriate to t he purposes for which it is intended. Where new agricultural buildings are proposed next to or close to existing residential properties, care must be taken to ensure that there is no unacceptable adverse impact through any activity, although it must be b orne in mind that many farming activities require buildings which are best sited, in landscape terms, close to existing building groups in the rural landscape.
General Policy 2 (b), (c), (g)
design to take into account the particular character and identity of the rural environment
