THIS APPLICATION IS REFERRED TO THE PLANNING COMMITTEE AS IT COULD BE CONSIDERED THAT THE DEVELOPMENT IS CONTRARY TO THE DEVELOPMENT PLAN AS THE SITE IS NOT DESIGNATED FOR DEVELOPMENT
1.0 THE SITE - 1.1 The application site represents the north-west corner of a field located to the north of the dwelling The Nab, at Nab Farm which is presently used for the storage of agricultural machinery. The field is accessed via a track which runs north from the A23 past the farm and farm buildings, and is located on the opposite side of the track to the east of a large livestock shed. The Field is located in the open countryside approx. 200m north of the A23; and, 800m north of the settlement boundary for Glen Vine. It is screened on its northern side by a bank/hedgerow containing mature trees and to the north-west by a group of mature trees, as well as the farm building.
2.0 THE PROPOSAL - 2.1 The full planning application proposes the erection of a single vertical wind turbine to be used to power the farmhouse and outbuildings on the landholding. The design for the turbine is proposed to employ a vertical axis turbine mounted on a pole to a maximum height of 11.0m above existing ground level. The 5 blade vertical rotor would measure 6.0m in height, and
4.0m in diameter. It would be fixed onto the pole at a height of 6.7m above ground, resulting in a 4.3m height of the rotor projecting above the pole. The vertical rotor differs to a horizontal rotor wind turbine in that the rotor sits atop the pole and spins like a top, whereas a horizontal rotor is akin to a windmill in operation and appearance.
2.2 The application was augmented with an Advice Note from Ecology Vannin Consultancy Services relating to a 'Wind Turbine Site Assessment and Advice' dated June, 2024. This was received on 30/8/24. The advice note covers details relating to a site walkover and the provision of ecological advice on the parcel of land known as The Nab Farm, Marown, Isle of Man, in relation to plans to erect a single wind turbine on the site. - 2.3 It advises (in part) at Section 5: "5.5 Wind turbines are known to have the ability to harm to birds and bats due to collisions with rotor blades, with the additional risk of barotrauma (injuries and mortality from sudden changes in air pressure around rotor blades). A widespread species that has not been recorded
but is likely present in the area is Common Pipistrelle (Pipistrellus pipistrellus). This species is relatively fast flying hawking species known to regularly forage with a 2-10m above ground level range and have been observed investigating new landscape structures including wind turbines. This presents a potential risk to individuals foraging and commuting in the area. It should be considered that an H type wind turbine is proposed in this instance which differs from the typical wind turbine design as it uses a cantilevered rotor design (see appendix VI). Whilst this design still presents a potential risk to harm, this risk will be reduced by its slower rotation speed (at the rotor tips) and is less likely to cause barotrauma events. Further, its 3D design and its horizontal rotation makes it more visible/detectable to birds and echolocating bats.
5.6 Reasonable methods to prevent rotor strikes should be employed where possible. This could include painting one rotor blade black and/or a textured coating on the turbine shaft. Further, attaching an ultrasonic emitting device may assist to deter bats from the immediate area of the turbine. These techniques have been shown to be effective at increasing visibility of turbines to bats and birds ultimately reducing incidence of rotor strikes.
5.7 We ultimately recommend the northernmost area within the redline boundary would be a suitable location for a wind turbine to be erected (photographs in Appendix I). The exact position should attempt to avoid any areas of existing grassland if possible and lie at least 15m away from the line of pine trees to the south. Therefore, the existing gravel around the northernmost area (within the redline boundary) would be the location of highest recommendation for the wind turbine. This location would reduce disturbance to existing grassland and provide an open buffer between the turbine and trees which is a potential flight corridor for bats and birds." - 5.8 On 17th September, 2024, the site location plan was superseded by Drawing No. 4; and the previous Block Plan was superseded by Drawing No. 10. These amendments were submitted at the request of the Ecosystems Policy Team on the back of Ecology Vannin's recommendation "that the turbine be located on the area of existing gravel in the northernmost area of the site, in order to reduce disturbance to the existing grassland and provide an open buffer between the turbine and trees."
3.00 RELEVANT SITE HISTORY - 3.1 The site has a history elated to agriculture and also introduced Equestrian uses and facilities in the 1990's and early 2000's. A barn conversion was approved to additional residential accommodation was approved, along with a pair of field shelters; an access road; and a sun lounge extension to the main dwelling. The main planning permission affecting the site are: - 3.2 PA 99/01903/B - Erection of an Agricultural Building. Permitted 20/3/00. - 3.3 PA 10/00059/B - Erection of building to provide indoor manège, stables and tack room Approved at Appeal - 8/12/2010. - 3.4 PA 04/02559/B - Amendments to approved conversion to existing barn to additional living accommodation (00/01224). Permitted 21/4/2005.
4.0 PLANNING POLICY - 4.1 The application site is not within an area designated for development, under the Isle of Man Development Plan Order 1982. The site is not within a Conservation Area; but is within an area zoned as High Landscape or Coastal Value and Scenic Significance. - 4.2 Under the Landscape Character Assessment the site falls within C3 Union Mills, Glen Vine and Crosby. The key characteristics are listed as:
The overall Landscape Strategy is stated as: "The overall strategy should be to conserve and enhance the character, quality and distinctiveness of the well-treed valley with some scattered and nucleated settlements."
4.3 The Isle of Man Strategic Plan 2016 contains advice on the installation of renewable energy facilities as follows: Paragraph 12.2.8: "The Department is fully supportive of the need to secure greater energy efficiency in new and existing development and has recently introduced additional energy efficiency requirements in the Building Regulations 2003." - 4.4 In the strategic Plan 2016, the following Policies are of relevance:
General Policy 2 indicates that: "Development which is in accordance with the land-use zoning and proposals in the appropriate Area Plan and with other policies of this Strategic Plan will normally be permitted, provided that the development:
Energy Policy 4 states "Development involving alternative sources of energy supply, including wind, water and tide power, and the use of solar panels, will be judged against the environmental objectives and policies set out in this Plan. Installations involving wind, water and tide power will require the submissions of an Environmental Impact Assessment."
4.4 Environment Policy 24: "Development which is likely to have a significant effect on the environment will be required:
4.5 Appendix 5 sets out further information and lists developments which will automatically require an Environmental Impact Assessment, including:
4.6 The means of assessing the impacts (good and bad) of a proposed development on the environment, prepared by, or on behalf of, the developer/applicant. An EIA should aim to ensure that the planning decision is made in the knowledge of all the likely environmental effects of the development, and of the proposals for mitigating adverse effects and enhancing positive effects. - 4.7 Transport Policies T4 and T7 relating to access to the site from the road network; and, onsite parking and turning provision, are of relevance. Transport Policy T10 relates to the location
and nature of development in and around the Island's airports, airfields, and air traffic control sites will be controlled in a manner which ensures that the safe and efficient use of these facilities by aircraft is not compromised.
4.8 The application site is located within an area identified as being "White Land" by the 1982 Development Order and as such represents the open countryside. Within the adopted Isle of Man Strategic Plan, the following is considered relevant in the assessment and determination of this application: Paragraph 12.2.8, which states:
"The Department is fully supportive of the need to secure greater energy efficiency in new and existing development and has recently introduced additional energy efficiency requirements in the Building Regulations 2003. Energy efficiency and the use of renewable energy sources are covered in General Policy 2(m) of the Building Regulations. At the same time the Department recognizes that renewable energy sources can have adverse environmental impacts…On a smaller scale, the popularity of domestic wind turbines has been increasing in recent years in response to rising energy prices and increasing awareness of climate change. Planning applications for domestic wind turbines are unlikely to require the submission of an Environmental Impact Assessment. The Department will assess any proposals for wind turbine installations by weighing the benefits of using such renewable energy sources against the environmental impact arising in any particular site."
5.0 REPRESENTATIONS - 5.1 The Department of Transport Highways Division (12/12/23) advises; "23/01367/B - After reviewing this Application, Highway Services HDC finds it to have no significant negative impact upon highway safety, network functionality and/or parking." - 5.2 Malew Parish Commissioners (21/12/23) raises 'NO OBJECTION' to this application. - 5.3 DEFA Ecosystems Policy Team (21/12/23) comments: "RE: PA 23/01367/B - Erection of a domestic wind turbine, The Nab, Top Road, Crosby - The Ecosystem Policy Team are concerned about the potential impact of the proposed domestic wind turbine on wildlife, particularly bats and birds.
Badly positioned turbines could lead to the direct mortality of bats and birds, damage to commuting and foraging habitat, displacement of populations and loss or damage of roosts or nest sites and so negative impacts need to be fully assessed and taken into account within the decision making process, and mitigation measures put in place to avoid impacts, as a priority, or minimise impacts.
Unfortunately there is limited literature on the impacts of micro-wind energy schemes on bats and birds and appropriate levels of survey effort, however, what is clear is that potential impacts need to be considered and survey effort determined on a case by case basis, proportionate to the scale of the project and potential impacts (Planning Guidance: Small Wind - A good practise guide November 2011 https://cdn.ymaws.com/www.renewableuk.com/resource/resmgr/publications/guides/WindPlan ningGuidance.pdf).
A precautionary approach is also recommended for free standing micro-turbines and they should not be located within 50m of a known bat roost, on buildings where bats are frequently observed, or on known bat flyways. At the very least for this site, it is likely we would likely need to see the turbine repositioned to keep it away from trees, boundary hedges and banks which are key habitat features for bats and birds, and away from any buildings used by bats or birds for foraging, roosting or nesting.
In order to comply with Environment Policy 4 and 5 of the Isle of Man Strategic Plan and the Wildlife Act 1990, The Ecosystem Policy Team therefore request that prior to determination of this application preliminary assessments for bats and birds are undertaken on the site by a suitably qualified ecological consultancy and reports detailing the findings submitted to Planning.
The employed ecological consultancy will need to be define what further assessment is required based on a desk study and walk over assessment of the site. Further assessment is likely to include activity surveys and roost surveys."
5.4 Subsequent to the receipt of the Advice Note from Ecology Vannin Consultancy Services relating to a 'Wind Turbine Site Assessment and Advice' dated June, 2024. The Ecosystems Policy Team (3/9/24) comments:
"The Ecosystem Policy Team can confirm that Ecology Vannin's Advice Note: Wind Turbine Site Assessment and Advice, dated June 2024, is all in order and that a suitable level of assessment has been undertaken.
Ecology Vannin recommend that the turbine be located on the area of existing gravel in the northernmost area of the site, in order to reduce disturbance to the existing grassland and provide an open buffer between the turbine and trees.
If this is different to the currently proposed location then we recommended that an updated site plan showing the reposition turbine is provided to Planning prior to determination of the application.
We also request that a condition is secured for the development to be undertaken in line with the Reasonable Avoidance Measures for Common Lizard contained in Appendix II of Ecology Vannin's Advice Note: Wind Turbine Site Assessment and Advice, dated June 2024."
5.5 No third party representations had been received by the Report drafting stage (4/9/24).
6.1 The main issues for consideration in the assessment of this application is the visual impact upon the surrounding area; and, the potential impact on wildlife and Protected Species from the siting of the wind turbine and the potential for rotor strike. Given the distance of the proposed turbine from any residential properties, it is not considered that any noise generated by the turbine would have an adverse impact upon the amenity of surrounding properties. - 6.2 In terms of visual impact, the turbine would be positioned a significant distance from the public highway, which is approximately 550 metres away at its closest point. The nearest property to the proposal site is "Coan Reayrt" located some 200 metres to the south-west of the proposal site; and, 1 and 2 Nab Cottages, Top Road some 400m to the south west. The tree cluster around the site and presence of farm buildings close-by to the west on the applicants land provide some backdrop helping to disguise the structure. The turbine would only really be visible from the east from points on the farm track leading from Top Road to Ballalough Farm where the farm dwelling is located approx. 1.0km to the north of the site. It is not readily visible from the highway 'Top Road'. It is considered that the substantial distance of the proposed turbine which is to be a vertical rotor turbine with the blades spinning round on a vertical axis as opposed to a horizontal rotor wind turbine - akin to a windmill - from both the highway and residential properties is sufficient to effectively mitigate any visual impact to an acceptable level. The majority of views would be from a substantial distance and therefore the visual impact would be limited. It is also noted the overall height of the proposed wind turbine would be no higher than the adjacent agricultural building. For this reason it is considered the proposal would comply with Environment Policy 2.
6.3 Regard also needs to be taken to ensure no significant adverse impacts through adverse noise levels to neighbouring residential properties, which can be created with wind turbines. As can be seen from the submitted location plan the nearest neighbouring residential property is approximately 200 metres away to the south-west of the application site, and therefore, it is considered that the proposal would not have an adverse impact upon residential amenity to this or any other nearby dwelling and consequently the proposal accords with Policies GP2 g) and ENV Policy 22 iii), and is acceptable.
6.3 Following consultations with the Ecosystems Policy Team, the applicant has submitted a Note entitled 'Wind Turbine Site Assessment and Advice, dated June 2024'. The Ecosystems Policy Team has assessed its content and raised no objections subject to an updated site plan being submitted showing the repositioning of the turbine prior to determination of the application; and, that a condition is secured for the development to be undertaken in line with the Reasonable Avoidance Measures for Common Lizard. It is considered that these are reasonable and in the case of the Reasonable Avoidance Measures for the Common Lizard, can be conditioned. - 6.4 The site location plan was revised and superseded by Drawing No. 4; and the previous Block Plan was revised and superseded by Drawing No. 10. These amendments, submitted at the request of the Ecosystems Policy Team on the back of Ecology Vannin's recommendation, to minimise the impact of the turbine by siting it on the area of existing gravel in the northernmost area of the site, to reduce disturbance to the existing grassland and to provide an open buffer between the turbine and trees, is acceptable. The application should be approved.
7.1 It is recommended that the application be approved subject to conditions. - 8.0 INTERESTED PERSON STATUS
