Appendix 4: Environmental Appraisal of Route Options

Section 0 – Ardmore to Edinbane

Route 0A – Existing Route

Description:

Broadly following the route of the existing trident OHL, from Ardmore substation to Dunvegan substation. The route crosses to the north / eastern side of the B886 road and passes to the rear of crofts and properties on the Waternish peninsula. The route then follows the A850 and a minor road to reach Dunvegan substation.

Review of Environmental Constraints:

Topics Potential Constraints RAG Rating

Designations This route option does not pass through any sites designated for Nature Conservation. The marine waters surrounding this coastline are designated as a SAC; the Inner Hebrides and the Minches SAC is designated for Harbour porpoise. The proposed development is not anticipated to result in any adverse impact to the marine environment.

Protected Species European Protected Species such as otter and bats could be present. Reptiles may also be present along the route. Further survey work would be required to determine their presence along the route. It is anticipated that opportunities would exist to minimise potential impacts on protected species.

Habitats This route largely passes through open moorland likely to comprise areas of blanket bog, heather moorland, peatlands and grassland. Areas of bog are likely to have been modified through grazing. There is the potential for areas of deep peat. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided. There are small areas of native woodland, typically to the west of the B886, but it is anticipated that impacts on these could be avoided.

Ornithology This route option follows the existing wood pole line which runs close to areas of settlement and roads. Hen harriers breed within the wider area and there are records of corncrake. White-tailed eagle are also known to frequent the area. All of these bird species are listed on Schedule 1 of the Wildlife and Countryside Act 1981. Potential for displacement and disturbance during construction should however be mitigated for through timing of these activities.

Hydrology / Geology This route crosses over surface water drinking protection zones at Trumpan and Stein, whilst properties within the vicinity of the route are likely to be served by private water supplies from watercourses crossed by the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that sections of this route would pass through Class 1 (strong likelihood of deep peat and priority peatland habitats). Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable, and inform construction practices and appropriate mitigation.

A number of watercourse crossings would be required along the length of the route. Impacts can be mitigated by good design.

Due consideration would need to be given to hydrological and geological features to inform an alignment and suitable mitigation measures to minimise potential impacts on these features.

Cultural Heritage


Designations This route intersects with two Scheduled Monuments: Trumpan Church, and Dun Hallin broch, and an alignment within this route has the potential for both direct and indirect (setting) impacts on these designated heritage assets. However, it is possible to avoid direct impacts, whilst indirect impacts could be minimised through sensitive alignment and siting of poles. The route also passes close to another Scheduled Monument – Annait, a monastic settlement, and there are listed buildings near Lower Halistra and Stein.

Potential impacts on all designated heritage assets would need to be given due consideration during routeing and alignment stages to ensure potential impacts are avoided or minimised.

Cultural Heritage Assets

There are numerous non-designated heritage assets that are recorded on the Highland Historic Environment Record in the Waternish Peninsula. This route passes through Trumpan Township (MHG 4739) and Lusta Township (MHG6139) and through a well-preserved field system at Hallistra (MHG5965). Other non-designated assets include brochs, sheiling huts, field systems, boundaries and areas of lazy bed cultivation.

Consideration would need to be given during the alignment stage to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People


Proximity to Dwellings

Numerous properties fall within or within the vicinity of this route at Trumpan, Halstra, Hallin, Stein, Lusta and Hornival. It is anticipated that the overhead line would be located to the east of the B886 and sufficiently upslope and distant to minimise potential impacts to properties in most cases. However, pinch points may exist along the route, for example at Trumpan whereby a balance will need to be struck between proximity to properties and other constraints such as Trumpan Church.

Landscape and Visual


Designations Around 11.5 km of this route passes through the North West Skye SLA. Whilst the proposed wood pole structures would replace an existing trident wood pole OHL in this area, the requirement to find a new, offline alignment and slightly more robust pole structure gives potential for increased prominence in coastal views and when crossing croftland, both of which are identified as Special Qualities of the designation. There is also the possibility of increased prominence in views from the A850 towards MacLeod’s Tables which is also a Special Quality of the SLA.

Landscape Character This route mostly passes through the Smooth Stepped Moorland and Linear Crofting LCTs with small areas of Scattered Crofting LCT near Trumpan. These three LCTs are considered able to accommodate some degree of development of the type proposed. The route also passes through small sections of Coniferous Woodland Plantation LCT which is considered to be less sensitive. Whilst the Proposed Development would replace an existing wood pole OHL in this section, the requirement to find a new off-line alignment and slightly more robust pole structure may lead to an increased potential for skylining above the hills which form the backdrop to settlements and croft land or form the potential for a new or distracting feature within coastal views.

SNH wildness mapping indicates a relatively low degree of wildness through most of this route, due to the influence of roads, properties and other modern artefacts. A moderate degree of wildness is present within the southern section of the route due to the perceived naturalness. As this line would comprise a replacement to the existing, albeit of a slightly more robust pole structure, notable wild land impacts are considered unlikely.

Visual The Proposed Development would be likely to feature in main views from properties at Trumpan. There is potential for rear views of the proposed route from properties and tourist developments around Stein, Halistra, Lusta and Hallin. Views would also be obtained from the B886 and other minor roads on the Waternish peninsula and the A850, all of which are popular tourist routes and from a Core Path near Stein. There may also be views from a viewpoint and car parking area at Trumpan Head depending on alignment.

Land Use


Agriculture This route crosses areas of agricultural land use, including land primarily suited to grassland (4.2), and land capable of use as improved grassland (5.1 and 5.2). No grade 1, 2 or 3 agricultural land is present in the vicinity of the route.

Forestry This route option is not anticipated to result in any significant areas of felling. The route does pass through a block of commercial forestry to the north east of Stein, but it is anticipated that potential impacts on this could be avoided or minimised.

Recreation This route includes two core paths: one near Stein and the second east of Dunvegan. It is anticipated that recreational opportunities would be unlikely to be affected.

Planning

Potential Constraints RAG Rating

Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the historic environment given the presence of features of national importance, the natural environment and areas of landscape importance. The RAG rating therefore reflects the potential for impact on some of these features, as noted above, albeit opportunities do exist to minimise potential impacts.

Proposals No notable proposals within the planning system identified within the vicinity of this route.

Route 0B – Garradh Mòr

Description:

Initially following the route of the existing trident OHL, from Ardmore crossing to the north east side of the B886 road and passing to the rear of crofts and properties at Upper Halstra, the route then crosses the Peninsula towards Gillen and follows an elevated route within and along the edge of forestry, to the west of the small hills which form the spine of the Waternish peninsula. The route then crosses the A850 and open moorland to reach Dunvegan substation.


Natural Heritage


Designations This route option does not pass through any sites designated for Nature Conservation. The marine waters surrounding this coastline are designated as a Special Area of Conservation (SAC); the Inner Hebrides and the Minches SAC is designated for Harbour porpoise. The proposed development is not anticipated to result in any adverse impacts to the marine environment.


Habitats This route largely passes through open moorland and commercial forestry. Open moorland areas are likely to comprise areas of blanket bog, heather moorland, peatlands and grassland. Areas of bog are likely to have been modified through grazing. There is the potential for areas of deep peat. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided.

Ornithology This route option would result in a new line across an area of the peninsula that does not currently have an overhead line, and more distant to settlement and roads compared to Route Option 0A. Hen harriers breed within the wider area and there are records of corncrake. White-tailed eagle are also known to frequent the area. All of these bird species are listed on Schedule 1 of the Wildlife and Countryside Act 1981. Potential for displacement and disturbance during construction should however be mitigated for through timing of these activities.

Hydrology / Geology This route crosses over a surface water drinking protection zone at Trumpan and passes close to a similarly designated zone at Stein, whilst properties within the vicinity of the route are likely to be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that sections of this route would pass through Class 1 (strong likelihood of deep peat and priority peatland habitats).

Designations This route intersects with two Scheduled Monuments: Trumpan Church, and Dun Hallin broch, and an alignment within this route has the potential for both direct and indirect (setting) impacts on these designated heritage assets. However, it is possible to avoid direct impacts, whilst indirect impacts could be minimised through sensitive alignment and siting of poles.

Potential impacts on all designated heritage assets would need be given due consideration during routeing and alignment stages to ensure potential impacts are avoided or minimised.


There are numerous non-designated heritage assets that are recorded on the Highland Historic Environment Record in the the Waternish Peninsula. This route passes through Trumpan Township and Hallistra field system and the impact will be largely the same as for Route Option A. Other constraints noted for Route Option A remain relevant, especially around Trumpan and Halistra.

As with Route Option 0A, consideration would need to be given during the alignment stage to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People



The route is generally distant from properties but there are properties that fall within or within the vicinity of this route at Trumpan, Upper Halistra and Gillen. It is anticipated that there are opportunities for the overhead line to be sufficiently distant from properties in most cases. However, pinch points may exist along the route, for example at Trumpan whereby a balance will need to be struck between proximity to properties and other constraints such as Trumpan Church.



Designations Around 4.5 km of this route passes through the North West Skye SLA with the remainder of the route located close to the east of the SLA. Within the SLA, the proposed wood pole structures would replace an existing trident wood pole OHL. However, the requirement to find a new, offline alignment and slightly more robust pole structure gives potential for increased prominence in coastal views and when crossing croftland, both of which are identified as Special Qualities of the designation.

Landscape Character This route mostly passes through the Smooth Stepped Moorland and Coniferous Woodland Plantation LCTs with small areas of Scattered Crofting and Linear Crofting also potentially affected. The Coniferous Woodland Plantation LCT is considered to have a low sensitivity to this type of development whilst the Smooth Stepped Moorland LCT and Scattered and Linear Crofting LCTs are all considered to have a medium sensitivity. There is the potential for the Proposed Development to become a prominent and potentially distracting feature as it passes areas around Gillen and Halistra and particularly around Trumpan (as per Routes 0A and 0C). The impacts may be slightly offset by the removal of the existing OHL along the settled coastline and crofting land near Lusta and Stein.

SNH wildness mapping indicates a relatively moderate degree of wildness through some of this route, and a lower degree of wildness where the influence of roads/tracks, properties and other modern artefacts are evident. The introduction of a new overhead line to some parts would have the potential to reduce the moderate degree of wildness locally to some degree.

Visual There would be potential views of the western part of this route and wayleave through forestry from elevated properties at Edinbane. There would also be potential views from some properties around Gillan of the route skylining above the inland hill depending on the alignment. At Trumpan the Proposed Development would be likely to feature in main views (as per Routes 0A and 0C). Views would also be obtained from the B886 and other minor roads on the Waternish peninsula and the A850, all of which are popular tourist routes, and from Core Paths through forestry at Greshornish and near Gillen. There may also be views from a viewpoint and car parking area at Trumpan Head depending on alignment (as per Routes 0A and 0C).

Land Use



Forestry This route passes through areas of commercial forestry for around half its length, and it is likely that a new wayleave would be required to accommodate a new overhead line.

Recreation This route includes two core paths: one near Stein and the second running through commercial forestry west of Grenshornish. It is anticipated that recreational opportunities would be unlikely to be affected.

Route 0C – Greshornish

Description:

This route follows a similar alignment to Route OB to Gillen. It then follows a route around the north-western coastal edge of the Waternish peninsula to Greshornish, following the minor Greshornish road back to the A850. The route then crosses the A850 and open moorland to reach Dunvegan substation.


Natural Heritage


Designations This route option does not pass through any sites designated for Nature Conservation. The marine waters surrounding this coastline are designated as a Special Area of Conservation (SAC); the Inner Hebrides and the Minches SAC is designated for Harbour porpoise. The proposed development is not anticipated to result in any adverse impacts to the marine environment.


Habitats This route largely passes through open moorland and commercial forestry. Open moorland areas are likely to comprise areas of blanket bog, heather moorland, peatlands and grassland. Areas of bog are likely to have been modified through grazing. There is the potential for areas of deep peat. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided.

Ornithology This route option would result in a new line across an area of the peninsula that does not currently have an overhead line, and more distant to settlement and roads compared to Route Option 0A. Hen harriers breed within the wider area and there are records of corncrake. White-tailed eagles are also known to frequent the area. All of these bird species are listed on Schedule 1 of the Wildlife and Countryside Act 1981. Potential for displacement and disturbance during construction should however be mitigated for through timing of these activities.

Hydrology / Geology This route crosses over a surface water drinking protection zone at Trumpan, whilst properties within the vicinity of the route are likely to be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that sections of this route would pass through Class 1 (strong likelihood of deep peat and priority peatland habitats). Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable and inform construction practices and appropriate mitigation.

A number of watercourse crossings would be required along the length of the route. Impacts can be mitigated by good design.

Cultural Heritage


Designations This route also intersects with the Trumpan Church Scheduled Monument, whilst running close to Dun Hallin broch Scheduled Monument. An alignment within this route has the potential for both direct (Trumpan Church) and indirect (setting) impacts on these designated heritage assets. However, it is possible to avoid direct impacts, whilst indirect impacts could be minimised through sensitive alignment and siting of poles. The route also includes listed buildings near Lower Halistra.

Potential impacts on all designated heritage assets would need be given due consideration during routeing and alignment stages to ensure potential impacts are avoided or minimised.


There are numerous non-designated heritage assets that are recorded on the Highland Historic Environment Record in the the Waternish Peninsula. Constraints within the vicinity of Trumpan and Halistra will be largely the same as for Route Option A and Option B. Other constraints noted for Route Option A and Option B remain relevant, especially around Trumpan and Halistra.

As with Route Option A, consideration would need to be given during the alignment stage to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People



The route is generally distant from properties but there are properties that fall within the vicinity of this route at Trumpan, Upper Halistra and Gillen. It is anticipated that there are opportunities for the overhead line to be sufficiently distant from properties in most cases. However, pinch points may exist along the route, for example at Trumpan whereby a balance will need to be struck between proximity to properties and other constraints such as Trumpan Church.



Designations Around 4.5 km of this route passes through the North West Skye SLA and around 4.5 km passes through the Greshornish SLA. Within the North West Skye SLA, the proposed wood pole structures would replace an existing trident wood pole OHL. However, the requirement to find a new, offline alignment and slightly more robust pole structure gives potential for increased prominence in coastal views and when crossing croftland, both of which are identified as Special Qualities of the designation. Within the Greshornish SLA the proposed wood pole structures would form a new feature with the potential to be prominent crossing the complex coastal landscapes and affecting the undisturbed character.

Landscape Character This route mostly passes through the Smooth Stepped Moorland and Coniferous Woodland Plantation LCTs with small areas of Scattered Crofting and Linear Crofting also potentially affected. The Coniferous Woodland Plantation LCT is considered to have a low sensitivity to this type of development whilst the Smooth Stepped Moorland LCT and Scattered and Linear Crofting LCTs are all considered to have a medium sensitivity. Around the north-eastern coast, the proposed new poles would form a new feature of the landscape. Although this falls within the Coniferous Woodland Plantation LCT, the undeveloped and rocky character of this coastline with little existing access is considered very sensitive to new development. It is likely that complex terrain would result in wood poles forming frequently prominent new features, which may be out of character. The dramatic crags of Score Horan are particularly sensitive along this coast. There is further potential for the Proposed Development to become a prominent and potentially distracting feature as it passes areas around Gillen and Halistra and particularly around Trumpan (as per Route Options 0A and 0B). The impacts may be slightly offset by the removal of the existing OHL along the settled coastline and crofting land near Lusta and Stein.

SNH wildness mapping indicates a moderate degree of wildness through some of this route, and a lower degree of wildness where the influence of roads/tracks, properties and other modern artefacts are evident (around Trumpan, Halistra, and the A850 near Upperglen and Lowerglen). The introduction of a new overhead line to some parts would have the potential to reduce the moderate degree of wildness locally to some degree, for example along the north-eastern coastal section of this route where there is particularly rugged and challenging terrain.

Visual There would be potential views of the western part of this route from elevated properties at Edinbane and at Upper Glen and Lower Glen on the road to Greshornish. There would also be potential views from properties around Gillan of the route navigating Score Horan. At Trumpan the Proposed Development would be likely to feature in main views (as per Route Options 0A and 0B). Views would also be obtained from the minor roads on the Waternish peninsula and the A850, which are popular tourist routes, and from Core Paths through forestry at Greshornish and near Gillen. There may also be views from a viewpoint and car parking area at Trumpan Head depending on alignment (as per Route Options 0A and 0B).

Land Use



Forestry This route passes through areas of commercial forestry, and it is likely that a new wayleave would be required to accommodate a new overhead line within commercial forest areas along the coast near Boad non Laogh and further south, to the west of Blackhill.

Recreation This route includes two core paths: one near Stein and the second running through commercial forestry west of Grenshornish. It is anticipated that recreational opportunities would be unlikely to be affected.

Section 0 – Dunvegan to Edinbane

Route 0D – Existing Route

Description:

Following the route of the existing wood pole overhead line from Dunvegan substation in a south easterly direction over open moorland toward Glen Heysdal and St John’s Chapel before heading in an easterly direction across moorland and through woodland towards Edinbane substation.


Natural Heritage


Designations This route option would potentially pass through the An Cleireach SSSI, a geological SSSI featuring Tertiary igneous intrusions. This route option follows the alignment of the existing wood pole line, which itself skirts the edge of this SSSI. It is anticipated that opportunities exist to minimise impacts on, or avoid this designated site altogether.

There are no other designated sites within the vicinity of this route option which are considered likely to result in direct or indirect impacts as a result of a new line within this route option.

Protected Species There are no designations covering protected species (terrestrial) through this route option.

European Protected Species such as otter and bats could be present. Reptiles may also be present along the route. Further survey work would be required to determine their presence along the route. It is anticipated that opportunities would exist to minimise potential impacts on protected species.

Habitats This route largely passes through open moorland comprising areas of blanket bog, heather moorland, peatlands and grassland. Areas of bog are likely to have been modified through grazing. There is the potential for areas of deep peat, but it is considered that there are opportunities to avoid these areas, as evidenced by the presence of the existing line. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided. There are small areas of native woodland at Glen Heysdal and Abhainn Bhaile Mheadhonaich but it is anticipated that impacts on these could be minimised or avoided. The route option would pass through an area of conifer plantation to the east of Balmeanach. A new wayleave would need to be created, adjacent to the existing wood pole line (as the existing line would be removed subsequently).

Ornithology This route option follows the existing wood pole line which runs close to areas of settlement and roads. Hen harriers breed within the wider area and there are records of corncrake. The eastern extent of the route also overlaps with the edge of a white-tailed eagle territory. All these bird species are listed on Schedule 1 of the Wildlife and Countryside Act 1981. Potential for displacement and disturbance during construction should however be mitigated through the timing of these activities.

Hydrology / Geology This route crosses over a surface water drinking protection zone near Ose, whilst properties within the vicinity of the route could be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that sections of this route would pass through Class 1 (strong likelihood of deep peat and priority peatland habitats). Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable, and inform construction practices and appropriate mitigation.

A few watercourse crossings would be required along the length of the route. Possible impacts can be mitigated by appropriate design.

This route passes partially through the An Cleireach GCR, north-west of Caroy. Opportunities exist to avoid this GCR.


Cultural Heritage


Designations This route contains no cultural heritage designations. There are a small number of Scheduled Monuments (e.g. Barpannan Chambered Cairns and Dun Feorlig Broch) located outside the route option, close to the coast or along the A863. Potential indirect impacts on these sites would need to be considered but are considered unlikely to be notable.


Only a small number of non-designated heritage assets have been recorded within this route option, partly reflecting the upland nature of the landscape and partly a lack of archaeological investigation (apart from Glen Heysdal, which has been surveyed as part of the Ben Aketil Wind Farm). Recorded assets include farmsteads and enclosures, shieling huts and, notably, remains of a broch, in Glen Heysdal.

There is little constraint to an alignment within this route option.

People



This route option would run within the vicinity of the crofting properties at Upper Feorlig and Balmeanach, as does the existing OHL which would be removed. Opportunities exist to minimise potential impacts on properties by routing to the north of the properties. This would be explored further at the alignment stage.



Designations No direct impacts to designated landscapes anticipated. The North West Skye SLA runs to the west of the A863. However, as this has a predominantly coastal aspect, any notable impact on the Special Qualities of the designation are unlikely.

Landscape Character This route is mostly within the Smooth Stepped Moorland LCT and also passes through Coniferous Woodland Plantation LCT, both of which are considered broadly accommodating of this type of development if well aligned. Depending on the alignment chosen, the route may also directly affect the Linear Crofting and Scattered Crofting LCTs which are considered to be more sensitive landscape types. In general, as this route would comprise the replacement of an existing wood pole OHL with a similar, though slightly more robust structure, it is considered unlikely to lead to any notable character impacts where a suitable alignment can be found.

SNH wildness mapping indicates a moderate degree of wildness through some parts of this route. However, this is reduced by the presence of the existing OHL and frequent influence of properties. As this line would comprise a replacement to the existing, notable wild land impacts are considered unlikely.

Visual Potential for visual impacts to recreational users of a core path in Glen Heysdal and properties at Upper Feorlig, and to a lesser extent, properties at Caroy and Balmeanach. Further consideration will be required at alignment stage to minimise potential impacts on these receptors. Potential visual impacts for travellers as route runs within the vicinity of the A863 road but these would be expected to be minimal. As this route would form a similar replacement to the existing wood pole OHL, the potential for notably increased visual impact is considered small.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with section of improved grassland (5.2 and 5.3) through crofts at Abhainn Bhaile Mheadhonaich and Glen Heysdal.

Forestry This route option is not anticipated to result in any significant areas of felling, although a new wayleave would be required through commercial forestry to the west of Edinbane substation.

Recreation The forest and wind farm access track near Edinbane substation is a core path, but it is anticipated that recreational opportunities would be unlikely to be affected.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the natural environment. The RAG rating therefore reflects the potential for impact on some of these features, as noted above, albeit opportunities do exist to minimise potential impacts.

Proposals The eastern part of this is within the vicinity of the consented Glen Ullinish wind farm and the proposed Ben Sca wind farm, although it is anticipated that interaction between these developments could be avoided.

Route 0E – Ben Aketil

Description:

Following an easterly / south easterly route from Dunvegan substation across open moorland, crossing Gleann Eoghainn before passing to the south of Ben Aketil. The route then follows topography to the west and south of An Cleireach before cutting through woodland towards Edinbane substation.


Natural Heritage


Designations This route option would potentially pass through the An Cleireach SSSI, a geological SSSI featuring Tertiary igneous intrusions. It is anticipated that opportunities exist to minimise impacts on, or avoid this designated site altogether.

There are no other designated sites within the vicinity of this route option which are considered likely to result in direct or indirect impacts as a result of a new line through this route.


European Protected Species such as otter and bats could be present. Reptiles may also be present along the route. Further survey work would be required to determine their presence along the route. It is anticipated that opportunities would exist to minimise potential impacts on protected species.

Habitats This route largely passes through open moorland comprising areas of blanket bog, heather moorland, peatlands and grassland. There is the potential for areas of deep peat. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided, particularly as existing access tracks are limited and temporary track solutions would be required. The route runs adjacent to a small area of native woodland to the north west of Edinbane substation, but impacts on this should be avoided. The route option would pass through an area of conifer plantation to the east of Balmeanach. A new wayleave would need to be created, adjacent to the existing wood pole line (as the existing line would be removed subsequently).

Ornithology Hen harriers breed within the wider area and there is one record of corncrake from 2014, also within the wider area. The eastern extent of the route also overlaps with the edge of a white-tailed eagle territory. All of these bird species are listed on Schedule 1 of the Wildlife and Countryside Act 1981. Potential for displacement and disturbance during construction should however be mitigated for through timing of these activities.

Hydrology / Geology This route crosses over a surface water drinking protection zone near Ose.

Priority peatland mapping suggests that the majority of this route would pass through Class 1 (strong likelihood of deep peat and priority peatland habitats), making it difficult to avoid. Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable and inform construction practices and appropriate mitigation.

A few watercourse crossings would be required along the length of the route. Possible impacts can be mitigated by appropriate design.

This route passes partially through the An Cleireach GCR, north-west of Caroy. Opportunities exist to avoid this GCR but require passage through forestry and / or priority 1 peatland habitat.


Cultural Heritage


Designations This route contains no cultural heritage designations.

There are a small number of Scheduled Monuments and Listed Buildings located outside the route option, close to the coast or along the A863. These sites are unlikely to be adversely affected by the route.


Only a small number of non-designated heritage assets have been recorded within this route option, partly reflecting the upland nature of the landscape and partly a lack of archaeological investigation (apart from Glen Heysdal, which has been surveyed as part of the Ben Aketil Wind Farm). Recorded features include farmsteads and shieling huts.

There is little constraint to an alignment within this route option.

People



A very small number of properties are present in this route at Balmeanach although it is anticipated that impacts on these properties could be minimised.



Designations No direct impacts to designated landscapes. The North West Skye SLA is located to the south and west but as the SLA has a generally coastal focus and the route is located mostly over 2 km from its edge impacts are considered unlikely.

Landscape Character This route is almost entirely within the Smooth Stepped Moorland LCT, whilst also passing through a small area of Coniferous Woodland LCT, both of which are considered broadly accommodating of this type of development if well aligned. The landscape is already influenced by features such as wind turbines and OHLs in some areas. However, this is an open, upland landscape, and this route would introduce a new feature to some areas which would have the potential to be prominent. However, this would be slightly offset by the removal of the existing OHL elsewhere in the landscape.

SNH wildness mapping indicates a moderate degree of wildness through this route. The introduction of a new overhead line to some parts would have the potential to reduce this locally to some degree although notable wild land impacts are considered unlikely bearing in mind the proximity to the Ben Aketil Wind Farm, c. 1-2km to the north.

Visual Visual impacts limited to rear views from properties within Balmeanach, and recreational users of a core path in Glen Heysdal. However this would be a replacement to the existing line in these areas and would be likely to appear similar. This route would result in the removal of the existing line from areas such as Upper Feorlig which would be locally beneficial.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Very minor interaction with sections of improved grassland (5.2) near Edinbane substation.

Forestry This route option is not anticipated to result in any significant areas of felling, although a new wayleave would be required through commercial forestry near Edinbane substation.

Recreation The forest and wind farm access track near Edinbane substation is a core path, but it is anticipated that recreational opportunities would be unlikely to be affected.

Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the natural environment. The RAG rating therefore reflects the potential for impact on some of these features, as noted above, albeit opportunities do exist to minimise potential impacts.

Proposals The eastern part of this is within the vicinity of the consented Glen Ullinish wind farm and the proposed Ben Sca wind farm, although it is anticipated that interaction between these developments could be avoided.

Section 1 – Edinbane to Sligachan

Route 1A – Existing Route

Description:

Following the route of the existing OHL from Edinbane substation to the south-west end of Loch Sligachan, with options to the west and east of Glen Varragill Forest. The route generally follows lower ground, skirting hills such as Beinn na Cloiche, Stròc-b’heinn and Meall an Fhuarain.


Natural Heritage


Designations The southern extent of this route option passes through the Cuillin Hills SPA, classified for 8 pairs of resident breeding golden eagles. This route option follows the alignment of the existing wood pole OHL which, fundamentally, would present fewer 'novel' potential impacts by following existing corridors of 'disturbance' on low ground (notably roads) and/or existing transmission lines (see also Ornithology below). Nevertheless, a Habitats Regulation Appraisal (HRA) would be required to be carried out by the competent authority upon submission of a consent application.

The southern extent of this route option also borders the Sligachan Peatlands SAC/SSSI, the qualifying features of which include blanket bog, dystrophic and oligotrophic lochs, vascular plants, transition mires and quaking bogs. Direct and indirect impacts on this designation should be avoidable by following an alignment on the northeast side of the A87 road.

If this route option linked with Route Option 2B, the SPA could be avoided at this point.

Protected Species European Protected Species such as otter and bats could be present. Other protected species including reptiles could be present. Further survey work would be required to determine their presence along the route.

Habitats See above (designations) regarding Sligachan SAC and SSSI. This route largely passes through open moorland comprising areas of blanket bog, heather moorland, peatlands and grassland. There is the potential for areas of deep peat, but it is considered that there are opportunities to avoid these areas, as evidenced by the presence of the existing OHL. Further survey work would be required to ensure impacts on these habitats are kept to a minimum, and areas of deeper peat are avoided. There are small areas of native woodland to the north of the route, but these could be avoided. Areas of conifer plantation are also common, but largely avoided by this route option (see Forestry below).

Ornithology This route option follows the existing wood pole OHL and could pass through approximately 2-4 km of the Cuillin Hills SPA. Within the SPA the existing OHL stays on the lower ground following the main road at around 500m distance from it, therefore a OHL replacing this should present a lower potential risk to golden eagles as they will already be less likely to utilise this area as they avoid areas of human disturbance and prefer ridge lines and the higher altitudinal levels of terrain features. This is supported by survey work in this area in relation to the Fort Augustus to Skye project carried out in 2018, but would be subject to further detailed assessment.

There are three active white-tailed eagle territories within 6 km of this route, plus information from surveys, sightings and satellite tags suggest use of the area around the route by this species. There is therefore the potential for collision as this species showed a tendency to fly at lower elevations.

Hen harriers, red-throated divers and greenshank breed within route option, so potential for displacement and disturbance during construction should be mitigated for through timing of these activities. Sensitive timing of construction activities would be required for breeding and foraging of a number of protected species including red-throated diver, greenshank, hen harrier, white-tailed eagle and golden eagle.

Hydrology / Geology This route crosses through or is in close proximity to a surface water drinking protection zone near Bracadale.

This route passes through, or in close proximity, to Ros a’ Mheallain GCR. Opportunities to minimise impacts on this site should exist.

Priority peatland mapping suggests that long sections of this route passes through Class 1 (strong likelihood of deep peat and priority peatland habitats). Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable, and inform construction practices and appropriate mitigation.

Number of watercourse crossings required throughout route, particularly at Glenmore and Glen Varragill. Mitigation can be afforded by good design.

Isolated properties likely to maintain private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Due consideration would need to be given to hydrological and geological features to inform an alignment and suitable mitigation measures to minimise potential effects on these features.

Cultural Heritage


Designations This route contains no cultural heritage designations. One Listed Building, B listed Sligachan Old Bridge, is located outside the southern end of the route option; Dun Arkaig broch (SM13662) lies close to the northern end of the route. Due consideration would need to be given to the setting of both, but adverse impacts are unlikely to be significant.


Few non-designated heritage assets have been recorded within this route option, partly reflecting the upland nature of the landscape and partly a lack of archaeological investigation. Recorded features are mostly shieling huts and post-mediaeval dykes and are unlikely to be constraints to an alignment within this route option. These assets are likely to be such that they can easily be avoided to minimise direct impacts.

Properties at Glenmore and Mugeary fall within the vicinity of this route. Opportunities do exist to identify an alignment at a sufficient distance from these properties but further consideration would need to be given during the alignment stage if this route option were taken forward (see also visual impacts below).



Designations No direct impacts to designated landscapes.

On approaching Sligachan there is the potential for indirect impacts to The Cuillin Hills NSA due to the appearance of steel structures in the foreground of views towards the mountains, a Special Quality of the NSA. Depending on the alignment chosen there is also the potential to affect the degree of perceived wildness of these landscapes which could also lead to an impact on the NSA and Cuillins WLA. Careful consideration of these aspects would therefore be required during the alignment stage.

Character This route is mostly within the Smooth Stepped Moorland LCT and Coniferous Woodland Plantation which are considered broadly accommodating of this type of development if well aligned.

It also directly affects Linear Crofting, Rocky Moorland and Rocky Undulating Plateau, and Rugged Massif which are all considered to be more sensitive landscape types. Although a replacement to an existing wood pole OHL, the steel structures would be taller and more prominent, though fewer in number than poles, and would potentially distract from small scale patterns within these landscapes.

SNH wildness mapping indicates a moderate degree of wildness through this route, reduced by the existing OHL. As the proposed OHL would be taller and potentially more prominent there may be some influence on wild land.

Visual Potential for visual impacts to properties at Glenmore and Mugeary within the main view with steel structures appearing more prominent and distracting in the view than the wood poles they would replace.

Notable visual sensitivities around Sligachan relating to hotel, campsite, walkers, sightseers and travellers on the road with potential for the OHL to appear within valued mountain and coastal views. Steep terrain in this area which could lead to difficulties finding an off-line route, and the taller steel structures are likely to lead to the proposed OHL being prominent. If this route option linked with Route Option 2B, potential impacts to Sligachan could be avoided, but the RAG Impact Rating assumes ‘worst case’ i.e. a connection with Route 2A.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with section of improved grassland (5.2) through the strath at Glenmore.

Forestry This route option does overlap forests at Glen Vic Askill and Glen Tungadal but it is anticipated that an alignment could be identified that avoids or minimises any felling. To the south, an option exists for an alignment to be routed to the north and east of Glen Varragill Forest, although there is a further option which would result in a new wayleave being created through Glen Varragill Forest.

Recreation The forest and wind farm access track at the commencement of this route is a core path. The route also crosses several small and minor roads: the B885 and Glenmore road as well as the main A87 and a coastal footpath at Sligachan. However, recreational opportunities would be unlikely to be affected on any of these routes.

Sligachan is an important tourist hub with the hotel, camping facilities and a large number of hill walking routes commencing here. However, this route would be unlikely to affect any recreational activities.

Route 1B – A863 - Bracadale

Description:

This route crosses Glen Bracadale, moving inland around Bracadale before following the A863 for much of its length towards Loch Sligachan.


Natural Heritage


Designations This route option passes through the Cuillin Hills SPA, classified for 8 pairs of resident breeding pairs of golden eagles. In contrast to Route Option 1A, this route would involve introducing a new feature through a longer section of the SPA which could result in potential impacts on this SPA. However, it would follow low ground besides the A87 which could reduce potential for displacement and disturbance.

This route option would traverse the Sligachan Peatlands SAC/SSSI, the qualifying features of which are noted above (see Route Option 1A). This route option has potential to damage designated habitats and have a negative impact on nationally rare plant species.

A HRA would be required to be carried out on both of these designations by the competent authority upon submission of a consent application.

Protected Species European Protected Species including otter and bats could be present. Other protected species including reptiles could be present. Further survey work would be required to determine their presence along the route.

Habitats Areas of heather moorland, peatlands and grassland are common through this route option, with areas of native woodland and small blocks of conifer plantation present. Further survey work would be required to ensure impacts on these habitats, deeper areas of peat and woodlands are avoided or kept to a minimum.

As described under Designations above, this route cannot avoid the northern part of the Sligachan SAC & SSSI. The blanket bog at the northern end of the SAC is a broad valley forming a mire complex with extensive areas of mainly dystrophic pools and unusual peat structures.

Ornithology This route passes through approx. 8km in length of the Cuillin Hills SPA and would introduce a new feature through this part of the SPA. Within the SPA it follows the route of a road along a valley, so could potentially present a low collision risk to golden eagle as they generally avoid areas of human disturbance and prefer to use ridge lines and the higher altitudinal levels of terrain features. The rating is however based on a precautionary approach. One active golden eagle territory centre in the SPA lies approximately 1 km from the route so there is some potential for impacts due to displacement, and also potential for the impacts of disturbance during construction.

At least two active white-tailed eagle territories are within 6 km of the route, plus location information from satellite tags and sightings suggest some use of the wider area by this species.

Hydrology / Geology Properties within the vicinity of this route could be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route passes through, or in close proximity, to Ros a’ Mheallain GCR. Opportunities to minimise impacts on this site should exist.

Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable and inform construction practices and appropriate mitigation.

Number of watercourse crossings. Some of these will have potentially steep crossing points, such as Allt na Guile and the various watercourses through Glen Drynoch. Effects can be mitigated by appropriate design.


Cultural Heritage



There is a small cluster of Scheduled Monuments and Listed Buildings around Bracadale Bay. One of these, Dun Beag, an iconic broch in a spectacular setting, is approximately 2.6km from the route option and potentially vulnerable to a negative visual impact, as is its less spectacular neighbour Dun Mor, also a Scheduled Monument, also around 2.6km from the route option. Dun Garsin broch is around 500m from the route option. The visual inter-relationship between these duns and other archaeological monuments (and natural features) to form a prehistoric landscape would require consideration in relation to an alignment through this route option.

One Listed Building, B listed Sligachan Old Bridge, is located outside the southern end of the route option.


There are recorded non-designated heritage assets of prehistoric date and post-mediaeval settlement and land use along this route option. There are clusters of recorded assets recorded in Glen Bracadale, at the northern end of the route, in Glen Vidigill, southeast of Bracadale, and along Glen Drynoch, alongside the A863. Prehistoric hut circles along Glen Drynoch, around Crossal, indicate prehistoric settlement along the river valley, which may be more widespread.

Consideration would need to be given at the alignment stage to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People


Proximity to dwellings

This route option does pass within the vicinity of a number of scattered properties, through Glen Drynoch in particular. There are opportunities within the route option to ensure a sufficient distance is maintained between an overhead line and properties, subject to the consideration of other constraints and topography.

Designations Potential direct impact to periphery of North West Skye SLA. This is its inland edge with the more valued landscapes being towards the coast although crofting land is also noted as a Special Quality of this SLA. Steel structures could be potentially prominent and distracting along the inland edge, particularly around Bracadale.

On approaching Sligachan, there is the potential for steel structures following this route to intrude across key views towards the Cuillin mountains, thereby potentially affecting this Special Quality of The Cuillin Hills NSA. Depending on the alignment chosen, there is also the potential to affect the degree of perceived wildness of these landscapes which could also lead to an indirect impact on the NSA and Cuillins WLA.

Landscape Character Mostly within Smooth Stepped Moorland LCT, where the edges of the LCT, or areas relating to other linear features, such as roads, are considered to be broadly accommodating of this type of development if well aligned. The western part crosses through the Rugged Massif and Rocky Moorland and Rocky Undulating Plateau LCTs, considered to have greater sensitivity.

This route may be locally difficult to accommodate within the landscape due to the terrain, particularly around Bracadale, Drynoch and Sligachan, with the potential for steel structures to be prominent around these areas.

SNH mapping indicates a relatively low degree of wildness for this route, with only small pockets of higher wildness. Potential wild land impacts are therefore considered unlikely for the majority of the route, although there is the potential for some degree of impact to the west of Sligachan depending on the alignment chosen.

Visual Likely impacts to residents and road users, particularly as the route crosses north-east of Bracadale.

Potential visual impacts for travellers of steel structures adjacent to A863 road. It is assumed an alignment would be on the inland side of the road, thus generally not affecting the impressive coastal views.

Potential visual impacts at Sligachan relating to hotel, campsite, walkers, sightseers and travellers on the road with coastal and mountain views affected from some directions. Steep terrain leading to potential routeing difficulties in this area and prominence of steel structures could intrude into valued mountain views, leading to potentially notable visual impacts.

Impacts would be slightly offset by removal of existing wood pole OHL from views from Glenmore and Mugeary.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.2) along the coast.

Forestry There is the potential for some removal of coniferous forestry through Glen Drynoch, although this could be kept to a minimum.

Recreation The forest and wind farm access track at the commencement of this route is a core path. The route also crosses the B885 and runs alongside the A863. This is a popular recreational route with impressive coastal views. However, recreational opportunities would be unlikely to be affected on any of these routes.

Sligachan is an important tourist hub with the hotel, camping facilities and a large number of hill walking routes commencing here. Visual impacts and potential physical impacts to the camp site have the potential to affect the recreational enjoyment of this area although potential impacts to the experience would be limited.

Route 1C – Tungadal – Sligachan

Description:

This route crosses Glen Bracadale and follows in a generally south-east direction, passing by the west of the Glen Tungadal plantation forest. It crosses higher ground than Route 1B, skirts the south face of Roineval and then heads east towards the A87, avoiding the plantation forestry east of Crossal. The route then rejoins Route 1A, heading toward Loch Sligachan.


Natural Heritage


Designations This route option passes through the Cuillin Hills SPA, classified for 8 pairs of resident breeding pairs of golden eagles. In contrast to Route Option 1A, this route would involve introducing a new feature through a longer section of the SPA which could result in potential impacts on this SPA. After a higher level section it would follow low ground besides the A87.

This route option would skirt the edge of the Sligachan Peatlands SAC/SSSI, the qualifying features of which are noted above (see Route Option 1A). Without careful selection of alignment, this route option has potential to damage designated habitats and have a negative impact on nationally rare plant species. This should be avoidable by following an alignment on the northeast side of the A87 road. This route also crosses part of the Roineval SSSI.


European Protected Species including otter and bats could be present. Other protected species including reptiles could be present. Further survey work would be required to determine their presence along the route.

Habitats Areas of heather moorland, peatlands and grassland are common through this route option. Further survey work would be required to ensure impacts on these habitats and deeper areas of peat are avoided or kept to a minimum.

With careful siting this route would avoid the northern part of the Sligachan SAC & SSSI and its blanket bog features.

Ornithology This route passes through between approx. 4 km – 8 km in length of the Cuillin Hills SPA. Approaching and within the SPA it crosses an area of high ground which is within the range of an active SPA golden eagle territory. Therefore potential impacts due to collision, displacement, and also potential for the impacts of disturbance during construction.

At least two active white-tailed eagle territories are within 6 km of the route, plus location information from surveys, satellite tags and sightings suggest use of the area by this species.

As it joins Route 1A near Sligachan flight activity of red-throated divers would require consideration.

Sensitive timing of construction activities would be required for breeding and foraging of a number of protected species including red-throated diver, greenshank, hen harrier, white-tailed eagle and golden eagle.

Cultural Heritage



There is a cluster of Scheduled Monuments and Listed Buildings around Bracadale Bay, but given the distance from this route option, indirect (setting) impacts are considered unlikely to be significant.

One Listed Building, B listed Sligachan Old Bridge, is located outside the southern end of the route option.


There are clusters of recorded non-designated heritage assets, including evidence for prehistoric and post-mediaeval settlement and land use in Glen Bracadale and Glen Vidigill. Smaller groups of remains are recorded within the route; at the northwest end along the River Ose, and at the southeast end, around Sligachan.

Designations Potential for direct impacts to periphery of North West Skye SLA where the route crosses Allt Mor. Elsewhere impacts would be indirect. This is its inland edge with the more valued landscapes being towards the coast although crofting land is also noted as a Special Quality of this SLA. Steel structures could be potentially prominent and distracting crossing Allt Mor, north-east of Bracadale.

On approaching Sligachan, there is the potential for steel structures following this route to intrude across key views towards the Cuillin mountains, thereby affecting this Special Quality of The Cuillin Hills NSA. Depending on the alignment chosen, there is also the potential to affect the degree of perceived wildness of these landscapes which could also lead to an indirect impact on the NSA and Cuillins WLA.

Landscape Character Mostly within Smooth Stepped Moorland LCT, but crossing through interior parts of the LCT that relate less to other linear features, such as roads, and where the perceived remoteness may be sensitive to change of the type proposed. The eastern part of the route, near Sligachan, crosses through parts of the Rocky Moorland and Rocky Undulating Plateau LCT and Rugged Massif LCT, considered to have high sensitivity, particularly in relation to the perceived sense of openness, remoteness and lack of focal features and human presence.

Small parts of the Coniferous Woodland Plantation LCT at the northern and southern end of the route are also overlapped by this route, but these are considered to have low sensitivity.

As the route traverses areas of higher and more remote ground, it may be locally difficult to accommodate within the landscape, particularly around Bracadale and Sligachan and areas of high ground in between where it passes over/close to several summits, including Roineval and Monadh Meadale, with the potential for steel structures to be prominent around these areas, introducing new focal features.

SNH mapping indicates a moderate degree of wildness for this route, with some small areas of higher wildness in higher more remote areas, where the absence of modern artefacts and perceived naturalness is more evident. There is the potential for some degree of impact on these interior areas and to the west of Sligachan depending on the alignment chosen.

Visual Likely impacts to residents and road users, particularly as the route crosses north-east of Bracadale and adjacent to the A87.

Potential visual impacts for travellers of steel structures where it passes within 1 – 2 km of the A863 road at higher elevation and may be skylined in views. Potential impacts for receptors along B8009, along west of Loch Harport who may experience the overhead line in elevated, skylined position.

Notable visual impacts at Sligachan relating to hotel, campsite, walkers, sightseers and travellers on the road with coastal and mountain views affected from some directions. Steep terrain leading to potential routeing difficulties in this area and prominence of steel structures could intrude into valued mountain views. This route appears to be situated on higher ground than Route 1B at Sligachan and potentially more prominent in views.

Impacts would be very slightly offset by removal of existing wood pole OHL from views from Glenmore and Mugeary.

Land Use

Forestry This route largely avoids areas of forestry, although it does overlap with areas at Glen Bracadale and by Alt Dubh near Sligachan. Careful routing on open ground to the north-east of Beinn na Cloiche could avoid the plantation forestry at Glen Vic Askill.

Recreation The forest and wind farm access track at the commencement of this route is a core path. The route also crosses the B885. Being situated on higher ground than Route 1B, the overhead line may be more visible to the surrounding area; however, recreational opportunities would be unlikely to be affected by this route.

Sligachan is an important tourist hub with the hotel, camping facilities and a large number of hill walking routes commencing here. Visual impacts and potential physical impacts to the camp site have the potential to affect the recreational enjoyment of this area although potential impacts to the experience would be limited.

The RAG rating therefore reflects the potential for impact on some of these features, as noted above.

Section 2 – Sligachan to Broadford

Route 2A – Existing

Description:

This route option broadly follows the route of the existing wood pole OHL, skirting the edge of The Cuillins. Crossing the head of Loch Sligachan, to the east of Sligachan, the route generally follows the A87 towards Sconser. Here, the route crosses the A87 and takes a route to the east of Gleann Torra-mhichaig toward Loch Ainort. From Loch Ainort, the route follows the A87 toward Luib, before heading to the south of Am Muall and Creag Strollemus before following a south easterly direction toward Broadford.


Natural Heritage


Designations This route option passes through (although predominantly along the edge of) approximately 18.5km of the Cuillins SPA, classified for 8 pairs of resident breeding golden eagles. Within the SPA the route option would generally follow the existing wood pole OHL, staying on lower ground and following the main road in the majority of places. It is considered therefore that a new OHL (steel structure) within this route and replacing the existing OHL would present a low potential risk to golden eagles as they will already be less likely to utilise this area, due to their avoidance of areas of human disturbance and preference for ridge lines and higher altitudinal levels of terrain features. This is supported by survey work in this area in relation to the Fort Augustus to Skye project carried out in 2018, but would be subject to further detailed assessment. A Habitats Regulations Assessment (HRA) would also be required to be carried out by the competent authority upon submission of a consent application.


European Protected Species such as otter and bats could be present, along with other protected species such as badger, pine marten, red squirrel and reptiles. Further survey work would be required to determine their presence along the route.

Habitats Predominant habitat along this route is heather moorland and peatlands, with the potential for deeper areas of peat in some sections (see below). Further survey work would be required to ensure potential impacts on these habitats are kept to a minimum.

Ornithology See Designations above regarding the Cuillins SPA and potential impacts to golden eagles.

There are two active white-tailed eagle territories within 6 km of the route, plus location information from surveys, satellite tags and sightings suggest use of the area by this species.

Other sensitivities include breeding greenshank, and possible merlin breeding habitat, plus waders, waterfowl and gulls feeding around the sea lochs with the potential for displacement and disturbance during construction which may require mitigation mainly through timing of these activities

Hydrology / Geology This route crosses over a surface water drinking protection zone near Dunan / An Dùnan, whilst properties within the vicinity of the route could be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route does not pass through any sites designated for geological importance.

Priority peatland mapping suggests that the section to the south of Am Meall and near Strollamus passes through Class 1 and 2 (strong likelihood of deep peat and priority peatland habitats). Further survey effort would be required to determine depth of peat along this route to ensure areas of deeper peat are avoided where practicable.

Number of watercourses to cross along route, particularly around Loch Sligachan where the steep slopes of the Cuillins generates some fast-flowing watercourses of various sizes, and waterfalls. Pollution risks and crossing design will require careful consideration.


Cultural Heritage


Designations There is a small cluster of Listed buildings at Luib within the route option. These are such that they can be easily avoided, and they have localised settings that are unlikely to be adversely affected. There is a Scheduled Monument (Old Corry cairns) at the southeastern end of the route, near Broadford.

Consideration will need to be given to potential impacts on the setting of Old Corry cairns.


There is an appreciable cluster of non-designated heritage assets around Strollamus, mostly representing post-mediaeval settlement and land use.

Consideration would need to be given to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People



There are properties that fall within this route at Sconser, Luib, Dunan and Strollamus with other properties close nearby. Further consideration would need to be given during the alignment stage to ensure a sufficient distance from these properties is maintained.



Designations Majority of route runs around edge of The Cuillin Hills NSA. Although the steel structures would replace existing wood poles through this route, the greater prominence of these structures in relation to the sensitivity of the landscape is considered likely to result in a high potential for constraint. Structures would be likely to be distracting in valued mountain views and may appear as a barrier across the base of the mountains.

The route also follows the edge of the Cuillins WLA, although the location close to other development (e.g. roads and housing) is considered likely to reduce the perceived wild land values of the WLA. As for the NSA, the larger, more robust steel structures would make this OHL a more prominent feature in comparison to the existing wood pole line.

Landscape Character Direct impacts on Rocky Moorland and Rocky Undulating Plateau, Linear Crofting, Rounded Hills and Rugged Massif – all sensitive landscape types to this type of development. A requirement to route off the existing alignment (potentially higher up the hill) and use of more prominent steel structures would lead to a greater impact than the existing wood pole OHL, intruding into views of mountains or coastal views and forming prominent new focal points and occasionally dominating where there are few other features (for example around the head of Loch Ainort).

The more robust, steel structures would potentially appear as a barrier or ring around the base of the hills. This impact could be enhanced in localised areas where the OHL may be difficult to accommodate due to steep terrain and limited space, particularly around Sligachan, the foot of Glamaig and Loch Ainort.

SNH mapping indicates a relatively low degree of wildness around this edge due to the existing road and housing. However, the presence of the OHL could lead to increased visibility from other areas within the mountains with potential for wild land impact.

Visual A new steel OHL within this route option has the potential to be more prominent and distracting in coastal and mountain views from the A87 than the existing wood pole OHL (which would be removed), and could act as a visual barrier between the road and mountains. Structures would also be potentially visible to the rear of properties at Sconser, Luib and Strollamus but not within the coastal views and would be likely to be prominent and distracting in views from parking laybys and tourist sites at Sligachan, Peinachorran and Loch Ainort.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with section of improved grassland (5.3) at Sconser.

Forestry There is some potential for removal of forestry as the route crosses the A87 and takes a route to the east of Gleann Torra-mhichaig, and again at Broadford as the route connects into Broadford substation. Opportunities do exist to minimise potential impacts and it is anticipated that, through discussion with Scottish Forestry and other landowners, a suitable route could be achieved that minimises potential impacts.

Recreation Commencing near Sligachan - an important tourist hub with hotel, campsite and a large number of hill walking routes commencing here. However, a route adjacent to the existing wood pole OHL in this area would be unlikely to affect any recreational activities.

This route would run parallel to the A87 but the potential to lead to any impacts on recreational use of this route is limited. It would also run parallel to a core path between Luib and Dunan which may affect recreational enjoyment more than the existing OHL.

Restrictions to alignment at Loch Ainort could lead to visual impact which could have an impact on parking areas and the appreciation of viewpoints here.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the natural environment given presence of designated sites of international and national importance, nationally designated landscapes and other areas of landscape importance. The RAG rating therefore reflects the potential for impact on some of these features, as noted above.

Proposals Planning permission was granted in September 2019 for the partial change of use of an agricultural shed to the creation of four holiday letting units at the head of Loch Ainort off the Moll Road (19/02676/Ful). This is a relatively small parcel of land that falls within the route option. However, it is located on the south east side of the minor road between the road and the mean high water level. It is not considered likely therefore that the proposed development would interact with this application. Other planning applications, typically housing related, within vicinity of A87 but unlikely to be within vicinity of OHL.

Route 2B – The Braes

Description:

This route option would avoid Sligachan by crossing Glen Varragill in an easterly direction, crossing moorland to the north of Ben Lee before heading south to Peinachorrain and Loch Sligachan. This option would require the OHL to span the narrows of Loch Sligachan within the vicinity of Peinachorrain and Sconser, before re-joining Route Option 2A at Sconser.


Natural Heritage


Designations In isolation, this route option avoids the Cuillins SPA / SSSI. However, at Sconser it would join Route Option 2A which itself is routed through the SPA toward Broadford (see Route Option 2A). The RAG rating is applied on the basis that the route requires connection with Route Option 2A.


Potential for European Protected Species such as otter and bats, and other protected species such as badger, pine marten, red squirrels and reptiles to be present. Further survey work would be required to determine their presence along the route.

Habitats This route has no designated areas for terrestrial habitats along its route. It is an area of predominantly heather moorland, with potential for some bog habitats, and areas of grassland on the lower ground. Areas of deeper peat are anticipated to the west of The Braes.

Ornithology The majority of this route avoids the Cuillins SPA therefore potential impacts on the SPA and golden eagles should be minimal for the route in isolation, although it would require to re-join Route Option 2A at Sconser.

Route over the higher moorland and the crossing of Loch Sligachan could present potential for constraint in relation to a number of protected species including red-throated diver, white-tailed eagle and other water birds. Further survey work and detailed assessment would be required to confirm potential impacts and inform appropriate mitigation if required. Sensitive timing of construction activities could be required for breeding and foraging of a number of protected species including red-throated diver, greenshank, hen harrier, white-tailed eagle and golden eagle.

Hydrology / Geology Priority peatland mapping suggests that the section to the west of The Braes passes through Class 1 (strong likelihood of deep peat and priority peatland habitats).

Some watercourse crossings would be required, as well as crossing both Loch Sligachan and Loch Ainort. There is potential for some properties within the vicinity of the route option to be served by private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Cultural Heritage


Designations Raasay House designed landscape and listed buildings, although at a distance of 3km, could be susceptible to a negative visual impact if steel structures break the horizon. Consideration will need to be given to potential impacts on the setting.


There are virtually no non-designated heritage assets recorded in the Historic Environment Record in the vicinity of Ben Lee; probably reflecting the steepness of the terrain.

There are clusters of non-designated heritage assets along the coastal strip around Sconser.


People



Properties at Peinachorrain and Sconser fall within this route. Further consideration at the alignment stage would be required to maintain a distance from these properties.



Designations In isolation, this route avoids The Cuillin Hills NSA apart from where it transitions to Route Option 2A at Sconser. An OHL within this route would introduce a new feature across mountain views from some areas such as Peinachorrain, but would avoid some of the most sensitive areas from where these views are obtained (e.g. Sligachan). This option would also remove some of the wirescape around the base of the mountains around Loch Sligachan with the removal of the existing wood pole OHL.

The route would join Route Option 2A at Sconser and therefore impacts from Sconser to Broadford would be as described for Route Option 2A.

Steel structures would potentially be visible along the coastline which forms a key view from the Raasay House GDL.

From Sconser, this route would also follow the edge of the Cuillins WLA and therefore the impacts described for Route Option 2A would also apply.

G

R


Landscape Character In isolation, there would be direct impacts on Smooth Stepped Moorland, Coniferous Woodland and Linear Crofting LCTs, all considered to have some ability to accommodate this type of development if well aligned, and Rugged Massif LCT which is considered of slightly greater sensitivity.

This part of the route follows a reasonably rational route through the landscape following transitions between LCTs and taking advantage of low points in the terrain and the less sensitive landscape types. Nevertheless, the steel structures would be large and prominent features in a landscape where there are no similar features present.

Greater landscape sensitivities are present at the narrows of Loch Sligachan where the towers would be very prominent in the coastal landscape. Spanning towers at either side of Loch Sligachan would be particularly prominent and distracting, likely to form a significant intrusion and barrier to the coastal views towards Raasay.

As the route would join Route Option 2A at Sconser the impacts from Sconser to Broadford would be as described for Route 2A. SNH mapping indicates relatively low degree of wildness throughout this route although it is likely that the tall steel structures would affect a sense of remoteness in some less inhabited areas away from the coast and main routes.

Visual Visual impacts would occur to views from properties and recreational users at Peinachorrain and Sconser, including golfers and passengers on or waiting for the Raasay Ferry and users of the A87. This is particularly relevant to the crossing of Loch Sligachan, and views from Sligachan area towards the spanning towers would also be likely to be highly distracting. This route would also be likely to be prominent and distracting in views from parking laybys and tourist sites around Loch Ainort, as described for Route Option 2A.

Land Use

Topics Potential Effects RAG Rating

Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with section of improved grassland (5.3) at Sconser.

Forestry No notable impacts on forestry. See also Route Option 2A for connection into Broadford substation.

Recreation There is the potential to affect a small picnic area and viewpoint at Peinnachorain depending on the location of the OHL crossing of Loch Sligachan for this route but potential to avoid. The Isle of Skye golf course at Sconser has the potential to result in a notable constraint to routing and could be physically affected, although there are opportunities to avoid

Section 3 – Broadford to Kyle Rhea


Description:

This option follows the route of the existing steel lattice OHL, heading east from Broadford substation, passing to the south of the populated A87 corridor. After passing through a forestry plantation to the south west of Kyleakin, the route then traverses around the headland at Loch Alsh before joining the crossing of Kyle Rhea.


Natural Heritage


Designations This route option would directly cross the Kinloch and Kyleakin Hills SAC and SSSI, comprising both woodland and open ground qualifying habitats. Qualifying features include alpine and sub alpine heaths, blanket bog, dry and wet heaths, mixed woodland on base rich soils associated with rocky slopes, western acidic oak woodland and otter. Direct impacts on the qualifying features of the SAC / SSSI would occur, and subject to further review of alignment and construction options, impacts on site integrity could occur. The potential for disturbance to otter during construction would also need to be taken into account.

Kinloch and Kyleakin Hills SSSI is further designated for its bryophyte assemblage and lichen assemblage qualifying features; there is the potential for direct effects and indirect effects (through alteration of shade, light penetration and micro-climate) on these qualifying features.

The route also crosses Abhainn Lusa, part of the Kinloch and Kyleakin Hills SAC. An alignment should be sort across this watercourse which seeks to avoid or minimise as far as practicable the need to fell trees to minimise impacts to woodland and bryophyte features.

The route also has the potential to pass through the Mointeach nan Lochain Dubha SAC and SSSI, although this would be over a relatively short distance and could potentially be avoided.

A short section (2 km at the most) of the edge of the Cuillins SPA may also be crossed, although as it would be following the existing steel lattice transmission OHL, which would be removed, and given eagles are less likely in this low altitude terrain and habitat, potential impacts are expected to be low.

It should also be noted that the Lochs Duich, Long and Alsh reefs SAC is a marine protected area for Burrowed mud and Flame shell beds. This would not be directly affected but indirect impacts during construction would need to be managed carefully.

A HRA may be required to be carried out by the Scottish Government upon submission of a consent application for each of the above designations, but certainly for the Kinloch and Kyleakin Hills SAC.

Protected Species The Kinloch and Kyleakin Hills SAC and SSSI are located at the east end of the route. Otter is a qualifying feature of the SAC and there is some potential for disturbance of otter during construction along the coast, dependent on the alignment chosen. Pine marten, badger, red squirrel, water vole, bats and reptiles may also be present. Further survey work would be required to determine their presence along the route.

R

A


Habitats This route option crosses the Kinloch and Kyleakin Hills SAC and SSSI. The SAC is crossed in two places. The first crossing is a very narrow section of 150-200m in width that follows the course of the Allt Mor / Abhaimm Lusa and includes mainly riparian woodland, wet heath and dry heath. The second crossing is along the north coast and this length of the route is characterised by both woodland and open ground – all qualifying habitats of the SAC (see Designations above). Other habitat types throughout the route include a combination of heather moorland, grassland, coniferous plantation and some blanket bog. There is woodland present that is noted on the Ancient Woodland Inventory (AWI).

Ornithology Route follows existing steel lattice OHL, which includes forestry and coastline. As noted in Designations (above), the route includes a short section through the Cuillins SPA. One active white-tailed eagle territory and an active golden eagle territory are located within 6 km of the route.

Sensitive timing of construction activities would be required for foraging and winter roosting of a number of protected species including white-tailed eagle and golden eagle, especially the areas around the Kyle Rhea crossing. Options for marking the new OHL near Kyle Rhea should be considered. Historical records of whooper swan flocks near Broadford, but no recent recordings.

Hydrology / Geology This route crosses over a surface water drinking protection zone near Harrapool, whilst properties within the vicinity of the route could be served by private water supplies from watercourses crossed by or within the vicinity of the route.

Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.


Priority peatland mapping suggests that the section to the south of Breakish as well as the area to the south of Mudlach (within the SAC) passes through Class 1 (strong likelihood of deep peat and priority peatland habitats).

Areas of open moorland and coniferous plantation with a number of water course crossings to consider, some of which comprise steep ravines. Crossing designs will need detailed consideration.

Due consideration would need to be given to hydrological and geological features to inform an alignment and suitable mitigation measures to minimise potential effects on these features, particularly in relation to qualifying habitats of the SAC (see Designations above).

Cultural Heritage


Designations A Scheduled Monument (Old Corry cairns) is within the route near Broadford / Ath Leathann and thus at risk of both a direct impact and setting impacts; however, opportunities exist to avoid this feature and limit impacts on setting.

There are listed buildings in the harbour area at Broadford, north east of route option, but these have localised settings within the harbour area. There are further listed buildings and one designed landscape at Kyle of Lochalsh and around Kyleakin, to the north of the route option; these too have largely localised settings and significant adverse effects are unlikely.


There are relatively few non-designated heritage assets recorded in the Historic Environment Record within the route option, most representing post-mediaeval settlement and land use. One, Runicaleach, a depopulated township overlooking the Kyle Rhea, lies at the southeastern end of this route option and extends much of the way across the width of the route option.

People



This option is routed to the south of Broadford and other settlements along the A87. Opportunities should exist to route line away from properties.



Designations The western end of this route lies close to The Cuillin Hills NSA but as the proposed OHL would replace an existing steel lattice OHL, the impact is unlikely to be notably greater. No notable impacts on the Kyle - Plockton SLA, which extends north from the Kyle of Lochalsh coastline, are anticipated.

Landscape Character Direct impacts on Smooth Stepped Moorland and Coniferous Woodland Plantation LCTs to west of Kyleakin, both considered broadly accommodating of this type of development if well aligned. Directly affecting the Rugged Massif LCT to east of Kyleakin, considered of generally high sensitivity to this type of development.

To the west, the landscape is broadly accommodating of this route and the replacement of an existing steel lattice OHL with steel structures is unlikely to lead to a very noticeably increased impact, although the new structures could appear more prominent.

To the east, although the steel structures would replace existing steel lattice towers the route could be difficult to accommodate along the more sensitive shore of Loch Alsh due to the steep slope. A new OHL higher up the hill could result in a potentially more prominent route. Difficulty in accommodating access for construction here could also lead to increased impacts on landscape character.

SNH mapping indicates relatively low degree of wildness to this route due to the presence of the existing OHL. However, lack of access along the Loch Alsh shore gives a sense of remoteness which could be affected by the issues highlighted above.

Visual Potential impacts to views from properties on southern outskirts of Broadford and the crofting townships to the east- Harrapool and Skulamus (generally within rear views from these properties). Also appearing in open views from minor roads and a core path across moorland. May be slightly more prominent than the existing OHL which it would replace but unlikely to notably increase impact.

Along its eastern coastal section, this route would potentially be visible in views across Loch Alsh from properties and key viewpoints on the A87, occasionally sky-lining. Access requirements may be difficult to reinstate and could result in scarring.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.1 and 5.3) around Broadford.

Forestry Removal of forestry required to accommodate an extension to the existing wayleave through areas of forestry at Broadford, Kyleakin and Kylerhea. Consideration will also need to be given to proposals for woodland restoration project at Kylerhea.

Recreation This route would cross a number of roads: the B8083, A851 and minor roads to Heaste and Kylerhea and may also cross a core path at Broadford but would be unlikely to affect recreational amenity of these routes. It is considered that this route would be unlikely to affect the experience of visitors to the Otter Haven on the shore of Kyle Rhea.

The RAG rating therefore reflects the potential for impact on some of these features, as noted above. Of particular relevance are potential impacts on the SAC.

Proposals The northern extents of the route does intersect a planning application for Construction of 54 affordable housing units and associated infrastructure (in application) adjacent to this route near Broadford (19/05003/PIP). However, assuming the new OHL remains close to the existing OHL there would be no direct interaction with this proposal. There are also other housing related applications within the vicinity of Broadford, Harrapool and Breakish but these are unlikely to be close to the OHL.

Route 3B – Glen Arroch

Description:

This route option provides an alternative to the easterly section of Route Option 3A. As opposed to following the headland around Loch Alsh, this route option follows the minor road through Glen Arroch toward Kylerhea. At Kylerhea, the route heads north to meet the existing crossing point of Kyle Rhea.


Natural Heritage


Designations As this route would require the western extent of Route Option 3A, potential impacts in relation to the Cuillins SPA and Mointeach nan Lochain Dubha SAC / SSSI would be as described for Route Option 3A.

This route option would be routed through Glen Arroch and would pass through the central section of the Kinloch and Kyleakin hills SAC and SSSI. This route through the SAC / SSSI would largely avoid the woodland habitat recognised as a qualifying feature of the SAC, whilst also avoiding larger areas of blanket bog (also a qualifying feature). This route option would still traverse qualifying features of the SAC but this would be to a lesser extent compared to Route Option 3A and opportunities to minimise impacts are further enabled by proximity to the existing road. Disturbance to otter during construction would need to be taken into account.


A HRA may be required to be carried out by the Scottish Government upon submission of a consent application for each of the above designations, but certainly the Kinloch and Kyleakin Hills SAC / SSSI.

Protected Species The Kinloch and Kyleakin Hills SAC and SSSI are located at the east end of the route. Otter is a qualifying feature of the SAC and there is some potential for disturbance of otter during construction along the coast, dependent on the alignment chosen. Pine marten, red squirrel, badger, water vole, bats and reptiles may also be present. Further survey work would be required to determine their presence along the route.

Habitats The length of the route through the Kinloch and Kyleakin Hills SAC and SSSI is characterised by wet heath, dry heath and potentially some blanket bog and subalpine heaths with associated sensitive bryophyte and lichen assemblages. These habitats are present as qualifying features of the SAC. Further survey effort would be required to minimise potential impacts to these habitats. There is the potential for areas of deep peat, but it is considered that there are opportunities to avoid these areas. Coniferous forestry plantation is located to the western and eastern extents of this route.

Ornithology See Route Option 3A for potential impacts to the Cuillins SPA and ornithological sensitivities around the western extent of Route Option 3A around Broadford. . One active golden eagle nest and one active white-tailed eagle nest within 6 km of the route, plus location information from surveys, satellite tags and sightings suggest use of the area around the route by these species, this a potential for collision. Survey work associated with the Fort Augustus to Skye Project noted that within this route flight activity of golden eagle was generally at higher elevations than the lower level route of this route option, whilst white-tailed eagle were mainly active at the coast or over the water suggesting careful routing of the OHL in the eastern end of Glen Arroch and around Kylerhea should lower the risk. Sensitive timing of construction activities would be required for breeding, foraging and winter roosting of a number of protected species including white-tailed eagle and golden eagle, especially the areas approaching and around Kylerhea.

Hydrology / Geology This route has the potential to pass through the Kylerhea Glen GCR site, although opportunities to avoid potential impacts to this site should exist.

Isolated properties are likely to utilise private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that this route would skirt the edges of some areas of Class 1 (strong likelihood of deep peat and priority peatland habitats). Further investigation and peat depth delineation is likely to be required.

This route option would run adjacent to, and cross tributaries of, Abhainn Lusa and Allt Mor, included within the Kinloch and Kyleakin Hills SAC and SSSI designation. The Bealach Udal geological site associated with the SSSI is located within this route option, in the valley between Beinn Bheag and Beinne na Grèine, and careful siting will be required to avoid this.


Cultural Heritage


Designations There are two listed buildings within the route option: at the slipway of the ferry at Kylerhea. These can be easily avoided and have localised settings that are unlikely to be significantly adversely affected. Two other listed buildings lie to the east of the east end of the route. These too have localised settings that are unlikely to be significantly adversely affected.


There is a cluster of non-designated heritage assets recorded in the Historic Environment Record within the route option, mostly along Glen Arroch, where there are numerous shieling settlements. Runicaleach, as described in Route 3A lies at the southeastern end of this route option and extends much of the way across the width of the route option.


People



Potential impacts within the vicinity of Broadford and other settlements along the A87 are as noted for Route Option A. Properties at Kylerhea would require due consideration at alignment stage to ensure an acceptable alignment.



Designations At the western end, where the route shares the same course as Route Option 3A, it lies close to The Cuillins NSA but as the proposed OHL would replace an existing steel lattice OHL, the impact is unlikely to be notably greater. There are no other designated landscapes that would be directly or indirectly affected by this option.

Landscape Character Direct impacts on Smooth Stepped Moorland and Coniferous Woodland Plantation LCTs to west of Glen Arroch, both considered broadly accommodating of this type of development if well aligned. Directly affecting the Rugged Massif LCT as it passes through Glen Arroch, considered to be of generally high sensitivity to this type of development.

To the west, the landscape is broadly accommodating of route and the replacement of an existing steel lattice OHL with steel structures is unlikely to lead to a very noticeably increased impact, although the new structures could appear more prominent.

To the east through Glen Arroch the proposed OHL would be a new feature in an area where few similar features are present. The route follows the minor road and river valley through the glen. Structures would likely be prominent in places. As it crosses to the rear of Kylerhea, it would form a prominent new linear feature seen against the hills and could affect the setting of the community and coastal views.

SNH mapping indicates this route to have a relatively low degree of wildness although there is a sense of remoteness to some of the open moorland and at the top of the glen as the public road is small, attractively built up with dry-stone and does not strongly influence the landscape.

Visual Initially following the same route as Route Option 3A, there would be potential rear views from properties on the southern outskirts of Broadford and the crofting townships to the west - Harrapool and Skulamus. Also appearing in open views from minor roads and a core path across moorland. Replacing the existing OHL, steel structures may be slightly more prominent but unlikely to notably increase impact.

Likely to be prominent in views from the minor road to Kylerhea and in key views down Kylerhea Glen from a viewpoint at the top of the glen. Also potentially within views from properties at Kylerhea but could be aligned to avoid the valued coastal views.

Would be present and potentially distracting in views descending the glen and along the coastline from properties and routes around Glenelg, including the ferry terminal and crossing.

Views from the RSPB reserve (Otter Haven) are also possible and could be notable depending on alignment.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value.

Forestry Some removal of forestry likely to be required to accommodate a new wayleave to the north of Glen Arroch and at Kylerhea.

Recreation This route runs parallel to the minor road to Kylerhea which is frequently used by tourists. Visual impacts have the potential for this to result in a limited impact on enjoyment of this route but are considered unlikely to affect its popularity.

There is the potential for this route to affect forestry at Otter Haven RSPB reserve which could affect enjoyment of this area, but this could be mitigated by choosing a sensitive alignment through the forest.

Potential visual impacts for those on the Glenelg Ferry are considered unlikely to affect recreational enjoyment.

Route 3C – A87

Description:

This route option is a variation to Route Option 3A which largely follows the alignment of the A87 from Breakish to Kyleakin.


Natural Heritage


Designations Potential impacts to the Mointeach nan Lochain Dubh SAC and Loch Ashaig SSSI should be avoidable within this route option. The route does pass over the Kinloch and Kyleakin Hills SAC / SSSI, crossing a very narrow section that follows the course of the Allt Mor and includes mainly riparian woodland, wet heath and dry heath. It would be important to minimise or avoid any felling of riparian woodland at this point. Felling may also have indirect effects on the SSSI bryophyte and lichen assemblage qualifying features.

The above constraints are specific to this Route Option. However, this route would also require the western and eastern extents of Route Option 3A which would be routed through the Cuillins SPA (potentially, and only for a short section) and Kinloch and Kyleakin Hills SAC / SSSI respectively. The RAG rating takes account of this.

Protected Species There is the potential for European Protected Species to be present such as otter and bats, and other protected species such as badger, water vole, pine marten, red squirrel and reptiles but further survey work would be required to determine their presence along the route. See also Route Option 3A for potential disturbance to otter, a qualifying feature of the Kinloch and Kyleakin Hills SAC.

Habitats Areas of heather moorland, peatlands, grasslands and coniferous woodland present. However, this route would also require the eastern extent of Route Option 3A which would be routed through the Kinloch and Kyleakin Hills SAC / SSSI. The RAG Rating takes account of this. Woodland listed on the Ancient Woodland Inventory (AWI) is located at the east of the route.

Ornithology Majority of route follows main road or is routed through forestry plantation which reduces the potential impact on bird species due to proximity to human disturbance. However, potential impacts associated with the western and eastern extents of Route Option 3A would also need to be taken into account. The RAG rating takes account of this.

Hydrology / Geology This route passes through the Loch Ashaig SSSI and GCR site, but avoidance of this site is anticipated to be likely at the alignment stage.

Priority peatland mapping suggests that this route would skirt the edges of some areas of Class 1 (strong likelihood of deep peat and priority peatland habitats). Peat depth probing likely to be required to delineate peat depths.

Properties within the vicinity of the route could be served by private water supplies from watercourses crossed by or within the vicinity of the route. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Areas of open moorland and coniferous plantation with a number of water course crossings to consider though mitigation is likely to be provided by appropriate design.

Due consideration would need to be given to hydrological and geological features to inform an alignment and suitable mitigation measures to minimise potential effects on these features (see also Route Option 3A).

Cultural Heritage


Designations There are further listed buildings and one designed landscape at Kyle of Lochalsh and around Kyleakin, to the north of the route option. These have largely localised settings and significant adverse impacts are unlikely.


There is a cluster of non-designated heritage assets recorded in the Historic Environment Record within the route option around Lower Breakish. These include prehistoric remains (including lithic find-spots) and mediaeval and post-medieval remains mostly within the confines of Broadford Airport.


People



Routed within the vicinity of the A87 corridor there are a number of properties located within this route, particularly at Harrapool and Breakish and also at Kyleakin. It is anticipated that an alignment could be achieved to the south of these properties, thereby ensuring sufficient distance to the OHL, although this would be confirmed at the alignment stage.



Designations At the western end, where the route shares the same course as Route Option 3A, it lies close to The Cuillin Hills NSA but as the proposed OHL would replace an existing steel lattice OHL, the impact is unlikely to be notably greater.

There is the potential for steel structures along this route above Kyleakin to be visible from the Kyle – Plockton SLA but within the forest context this is considered unlikely to lead to any notable impact on this designation.

Landscape Character Direct impacts on Smooth Stepped Moorland, Linear Crofting and Coniferous Woodland Plantation LCTs to west of Kyleakin, generally considered broadly accommodating of this type of development if well aligned. Directly affecting the Rugged Massif LCT to east of Kyleakin, considered of generally high sensitivity to this type of development.

To the west, the landscape is broadly accommodating of route and the replacement of an existing steel lattice OHL with steel structures unlikely to lead to a very noticeably increased impact, although the new structures could appear more prominent.

However, when considering the route in the context of its connection with Route Option 3A to the east, here there is the likelihood for impacts on landscape character (see Route Option 3A). The RAG rating takes this into account.

Visual Initially following the same route as Route Option 3A, there would be potential rear views from properties on southern outskirt of Broadford and the crofting townships to the west - Harrapool and Skulamus. Replacing the existing OHL, steel structures may be slightly more prominent but unlikely to notably increase impact. This route would also affect properties at Breakish, becoming a closer feature than the existing OHL in rear views. There would also be potential views from properties at the west side of Kyleakin.

Appearing in open views to users of minor roads and a core path across moorland and also likely to be prominent within views obtained by users of the A87 (travellers, tourists, recreational users etc.).

Steel structures would also be potentially prominent from the Cnoc a’ Mhadaidh Ruaidh woodland walking route and Core Path near Kyleakin, including felling for a wayleave, depending on the alignment. Further east, the route would re-join Route Option 3A and potential impacts would be as previously noted (see Route Option 3A). The RAG rating takes this into account.

Land Use



Forestry A new wayleave would be required through the forestry along this section. See also potential impacts associated with Route Option 3A.

Recreation The route crosses a woodland walking route near to Kyleakin (Cnoc a'Mhadaidh Ruaidh) circuit and a wayleave here has the potential to affect the recreational amenity of this route.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the natural environment given presence of designated sites of international and national importance, and landscape and visual sensitivities. The RAG rating therefore reflects the potential for impact on some of these features, as noted above. Of particular relevance are potential impacts on the SAC (see also Route Option 3A).

Proposals There are proposals in the planning system within the proximity of settlements at Broadford, Harrapool and Breakish but these are unlikely to be close to the OHL. See also Route Option 3A.

Route 3D – Beinn na Caillich

Description:

This option would comprise an alternative route to the eastern extent of Route Option 3A which bisects the Kinloch and Kyleakin Hills SAC and SSSI, from a point close to the existing steel lattice OHL at Kyleakin to the crossing point of Kyle Rhea. As the route crosses the minor Glen Arroch road, it heads in an easterly direction passing through Bealach nam Mulachag, before heading in a north-easterly direction towards the existing OHL crossing of Kyle Rhea.


Natural Heritage


Designations As this route would require the western extent of Route Option 3A, potential impacts in relation to the Cuillins SPA and Mointeach nan Lochain Dubha SAC / SSSI would be as described for Route Option 3A.

This route through the Kinloch and Kyleakin Hills SAC / SSSI would be largely to the south of the woodland habitat recognised as a qualifying feature of the SAC, but would still traverse through other qualifying features such as blanket bog, wet and dry heaths. Disturbance to otter during construction would need to be taken into account.



Protected Species As noted above, otter is a qualifying feature of the SAC. Potential disturbance to otter during construction would need to be taken into account. Potential for badger, pine marten, red squirrel, water vole, bats and reptiles to be present.

Habitats This route option would pass through the Kinloch and Kyleakin Hills SAC and SSSI. As noted in Designations above, the route option would pass through areas of wet heath, dry heath and blanket bog. These habitats are listed on the Habitats Directive as Annex 1 Habitats and direct impacts on these habitats are anticipated. Montane habitats, plants and alpine moss heaths could be present on hill and mountain tops, but will likely be avoided.

Ornithology This route option passes within active golden eagle territory and is in part routed through an area of high use by eagles where no other infrastructure currently exists. The route therefore presents a potential risk to golden eagles, in terms of collision risk, displacement and disturbance during construction. One active white-tailed eagle nest also exists within 6 km of the route, plus location information from surveys, satellite tags and sightings suggest use of the area around the route by this species. Potential effects of disturbance during construction will require mitigation mainly through timing of construction activities. The route option would require the western extent of Route Option 3A and therefore potential impacts here are also relevant (see Route Option 3A).

Hydrology / Geology Isolated properties are likely to utlise private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route passes through the Kinloch and Kyleakin Hills SSSI which is a mixed SSSI (geological / biological) characterised by nationally important structural and metamorphic geology. The two geological sites recognised within the SSSI are not located within, or close to the route option. Priority peatland mapping indicates that the section to the east of the forestry plantation as the route emerges and begins to cross the open moorland towards Allt na Plaide passes through or adjacent to Class 1 (strong likelihood of deep peat and priority peatland habitats). Habitat classifications noted above demonstrate areas of peat will be present along this route option. Peat probing to delineate peat depths is likely to be required.

Areas of open moorland and coniferous plantation with a number of watercourse crossings to consider.


Cultural Heritage


Designations There are no designated cultural heritage sites within or in the vicinity of this route option.


Runicaleach, as described in Route 3A, lies within eastern end of this route option and extends much of the way across the width of the route option. There are no other recorded cultural heritage features within this route option.

Consideration would need to be given to avoid and minimise potential impacts to Runicaleach Township, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People



There are no properties within the vicinity of this route option. However, the route option would require the western extent of Route Option 3A and therefore proximity to properties at Broadford and Harrapool would require consideration (see Route Option 3A).



Designations At the western end, where the route shares the same course as Route Option 3A, it lies close to The Cuillins NSA but as the proposed OHL would replace an existing steel lattice OHL, the impact is unlikely to be notably greater.

There is the potential for steel structures high on the hill above Kyleakin to be visible from the Kyle – Plockton SLA although at the distance involved this is unlikely to affect the key qualities of the designation.

Landscape Character This route option would directly affect the Rugged Massif LCT to east of Kyleakin, considered of generally high sensitivity to this type of development. The lack of access and other built infrastructure through the Rugged Massif LCT provides a sense of remoteness which would be affected by the OHL through this area. The steel structures have the potential to be prominent through the elevated landscape when seen from some lower areas which may diminish its sense of scale and contrast when seen from areas around the coast to the north and from the opposite shore of Kyle Rhea.

SNH mapping indicates a moderate degree of wildness greatest through the elevated higher sections. The prominence of the steel structures through this area would be likely to diminish this perception.

The route option would require the western extent of Route Option 3A and therefore potential impacts here are also relevant (see Route Option 3A).

Visual The steel structures would be potentially visible, high on the hillside from properties and routes in and around Kyleakin and Kyle of Lochalsh, potentially skylining at times, and prominent from Glenelg and the Glenelg ferry terminal, passing through the Bealach and descending towards the sea crossing. Steel structures would also be potentially prominent from the Cnoc a’ Mhadaidh Ruaidh woodland walking route and Core Path near Kyleakin, including felling for a wayleave, depending on the alignment. Further east, a new wayleave through native woodland may be required.


Land Use


Agriculture Outwith forested areas land is rough grazing with limited agricultural value.

Forestry Removal of forestry required to accommodate an extension to the existing wayleave through areas of forestry at Broadford (as per Route Option 3A), Kyleakin and Kylerhea. Consideration will also need to be given to proposals for woodland restoration project at Kylerhea.

Recreation There are no designated footpaths or hill tracks through this area. The Cnoc a’ Mhadaidh Ruaidh woodland walking route and core path is situated approximately 1km north of this route at its closest point within forested area. Otter haven is a popular visitor attraction within the vicinity of this route option, but the route through the woodland / forestry to the existing crossing point would be at least 1km to the north of the otter hide and potential impacts on recreation are expected to be minimal. The route option would require the western extent of Route Option 3A and therefore potential impacts here are also relevant (see Route Option 3A).

Route 3E – Coire na Coinnich

Description:

This option would comprise an alternative route to the eastern extent of Route Option 3B which would cut off the settled area around Kylerhea by rising over the shoulder of Beinn Bhuidhe via Coire na Coinnich and descending via Coire Buidhe to the existing crossing point over Kyle Rhea.


Natural Heritage


Designations As this route would require the western extent of Route Option 3A / 3B, potential impacts in relation to the Cuillins SPA and Mointeach nan Lochain Dubha SAC / SSSI would be as described for Route Option 3A / 3B.

This route option would be routed through Glen Arroch and would pass through the central section of the Kinloch and Kyleakin hills SAC and SSSI. This route through the SAC / SSSI would largely avoid the woodland habitat recognised as a qualifying feature of the SAC, but would still traverse through other qualifying features such as blanket bog, wet and dry heaths. Disturbance to otter during construction would need to be taken into account.



Protected Species As noted above, otter is a qualifying feature of the SAC. Potential disturbance to otter during construction would need to be taken into account. Potential for pine marten, bats and reptiles to be present.

Habitats This route option would pass through the Kinloch and Kyleakin Hills SAC and SSSI. As noted in Designations above, the route option would pass through areas of wet heath, dry heath and Blanket Bog. These habitats are listed on the Habitats Directive as Annex 1 Habitats and direct impacts on these habitats are anticipated. Montane habitats, plants and alpine moss heaths could be present on hill and mountain tops, but will likely be avoided.

Ornithology This route option passes within an active golden eagle territory and is in part routed through an area of high use by eagles where no other infrastructure currently exists. The route therefore presents a potential risk to golden eagles, in terms of collision risk, displacement and disturbance during construction. One active white-tailed eagle nest also exists within 6 km of the route, plus location information from surveys, satellite tags and sightings suggest use of the area around the route by this species. Potential effects of disturbance during construction will require mitigation mainly through timing of construction activities. The route option would require the western extent of Route Option 3A and 3B and therefore potential impacts here are also relevant (see Route Option 3A/3B).

Hydrology / Geology This route passes through the Kinloch and Kyleakin Hills SSSI which is a mixed SSSI (geological / biological) characterised by nationally important structural and metamorphic geology. The Bealach Udal geological site associated with the SSSI is located within this route option, in the valley between Beinn Bheag and Beinne na Grèine, and careful siting will be required to avoid this.

Isolated properties are likely to utilise private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping indicates that the section to the east of the forestry plantation as the route emerges and begins to cross the open moorland towards Allt na Plaide passes through or adjacent to Class 1 (strong likelihood of deep peat and priority peatland habitats). Habitat classifications noted above demonstrate areas of peat will be present along this route option.

Areas of open moorland and coniferous plantation with a number of watercourse crossings to consider, though effects can be mitigated by appropriate design.


Cultural Heritage


Designations There are no designated cultural heritage sites within this route option.

There are four B listed buildings at the slipway of the ferry at Kylerhea. These can be easily avoided and have localised settings that are unlikely to be significantly adversely affected.


Runicaleach, as described in Route 3A lies at the southeastern end of this route option and extends much of the way across the width of the route option. There is also a cluster of non-designated heritage assets recorded in the Historic Environment Record along Glen Arroch, where there are numerous shieling settlements.


People



There are no properties within the vicinity of this route option. However, the route option would require the western extent of Route Option 3A and therefore proximity to properties at Broadford and Harrapool would require consideration (see Route Option 3A).



Designations There are no designated landscapes within the vicinity of this route option. As the route would require to connect with Route Option 3A, the western extent of Route Option 3A lies close to The Cuillin Hills NSA but as the proposed OHL would replace an existing steel lattice OHL, the impact is unlikely to be notably greater.

Landscape Character This route option would directly affect the Rugged Massif LCT as it rises over the higher ground considered of generally high sensitivity to this type of development. Ascending the higher hillside on the northern side of Glen Arroch, the proposed OHL would be a new feature in an area where few similar features are present. The route follows a reasonably rational route through topography but would cross rugged ground and steep side slopes which may lead to increased impacts for construction access. There is the potential for skylining as the route passes over Beinn Bhuidhe and the steel structures on the high slopes would be prominent in some areas.

SNH mapping indicates a moderate degree of wildness, greatest through the elevated higher sections. The prominence of the steel structures through this area would be likely to diminish this perception.


Visual Likely to be prominent in views from the upper part of the minor road to Kylerhea and visible in part from lower sections but not prominent from Kylerhea properties. Would be potentially prominent and detracting in views from the east side of Kyle Rhea, seen crossing the high hillside from Glenelg and descending to the crossing point from the ferry terminal area (rating reflects these likely impacts). May also be more distantly seen descending the hill from properties and routes on the northern coastline of Loch Alsh.

The route option would require the western extent of Route Option 3A / 3B and therefore potential impacts here are also relevant (see Route Option 3A).

Land Use


Agriculture Outwith forested areas land is rough grazing with limited agricultural value.

Forestry Removal of forestry required to accommodate an extension to the existing wayleave through areas of forestry at Broadford (as per Route Option 3A), North of Glen Arroch (as per Route Option 3B) and Kylerhea. Consideration will also need to be given to proposals for woodland restoration project at Kylerhea.

Recreation There are no designated footpaths or hill tracks through this area. Otter haven is a popular visitor attraction within the vicinity of this route option, but the route through the forestry to the existing crossing point would be at least 1km to the north of the otter hide and potential impacts on recreation are expected to be minimal.

Section 4 – Kyle Rhea to Loch Cuaich / Loch Cluanie


Description:

This option follows the route of the existing steel lattice OHL from Kyle Rhea to Quoich Dam. The section of this route from Balvraid to Kinloch Hourn is an extremely remote, complex and rugged landscape.


Natural Heritage


Designations The only designated sites for natural heritage along this route option are sites of geological importance. Druim loasal SSSI and GCR, and Quoich spillway SSSI are located within the route option and noted for their moine geological features. It is anticipated that these sites could be avoided during the alignment stage. The route also runs adjacent to the Kinloch Hourn GCR but it is anticipated that this site would also be avoided.

Protected Species European Protected Species include potential for otter and bats. There is also the potential for other protected species to be present including pine marten, red squirrel, water voles, badgers and reptiles. Further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, grassland on the lower areas, and areas of mixed and broadleaved woodland. These woodlands comprise native woodland, predominantly classified as upland birchwood, and ancient woodland and some areas are noted on the Ancient Woodland Inventory (AWI). Some felling of semi-natural woodland may be required at Druim na Leitire and on the south bank of Glenmore River, the latter could be avoided or minimised. Either side of Kinloch Hourn further felling required, mostly in relatively open semi-natural wood but a stand of native pine is adjacent to existing OHL at Kinloch Hourn. East of Kinloch Hourn route crosses the Lochourn River Caledonian Pine buffer zone. The remnant Scot’s pine forest (UK Priority habitat) is avoidable. Depending on routing, felling within an area of semi-natural woodland may be required on the north bank of Loch Cuaich. Further consideration at alignment stage would be required to minimise potential impacts on these woodland areas in particular.

G

G

A


Ornithology There are no ornithological designations covering this route. There are 2 to 3 active golden eagle territories between Kinloch Hourn and Glenelg within the vicinity of this route. Therefore there is a possibility of some loss of territory due to displacement and risk of collision, although as the new OHL route is mainly along the lower ground and close to the existing OHL this risk is likely to be minimised. There is potential for disturbance during construction which can be mitigated with careful timing.

Field surveys in 2016 on eastern part of this route were completed for black-throated diver, red-throated diver and common scoter flight activity. The diver species’ use the sea from Kinloch Hourn west and the inland Loch Cuaich, so flights to and from the West Inverness-shire Lochs SPA may occur along this route although only two red-throated divers (not SPA qualifying interest) were observed potentially following this flight path. Following the route of the existing transmission OHL will minimise any 'novel' impact of a new OHL along this route.

Black-throated diver and red- throated diver potential breeding lochs exist within the areas surrounding the route, therefore potential for collision, displacement and disturbance which may require mitigation. Again, keeping the OHL low in the valleys will ensure low risk of collision for these species also.

Hydrology / Geology

This route crosses over a surface water drinking protection zone associated with Loch Beinn a’ Chaoinich and Loch a’ Mhuilinn. Private water supply infrastructure present in this section (e.g. at Glenmore and Kinloch Hourn). Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route would pass through, or in the vicinity of, the Druim Iosal GCR, as well as passing close to Kinloch Hourn GCR.

Priority peatland mapping suggests that there are sections of Class 2 (strong likelihood of deep peat and priority peatland habitats) at intervals throughout this section. Peat depth probing may be required to inform the final alignement.

Numerous watercourse crossings to consider throughout route though potential effects can be mitigated by appropriate design.


Cultural Heritage


Designations One B listed building within the route option: hydroelectric power station infrastructure at the east end of Loch Cuaich, industrial buildings of 1950s date, which should exist reasonably harmoniously with modern features of electricity generation and transmission.

There are other listed buildings outside of, but in close proximity, to the route option; at Kinloch Hourn and at Galltair/Glenelg. These have localised settings that are unlikely to be significantly adversely affected by the proposed development.

There is a group of Scheduled Monuments at the northwest end of, but outside of, the route option, around Glenelg including Dun Grugaig Dun, Dun Telve and Dun Troddan Brochs, and Bernera Barracks.

Consideration of potential impacts on their setting would need to be undertaken during alignment studies. It is anticipated that opportunities to minimise potential impacts on the setting of these sites exist, particularly given their distance from the route option and the nature of local topography.

A

G



There are clusters of non-designated heritage assets recorded in the Historic Environment Record: east of Glenelg, along the C1223, and around Kinloch Hourn. These are mostly of medieval-post-medieval date and include farmsteads and shielings, which are easily avoided.

There are few recorded sites elsewhere along this route option and little by way of constraint to routing an alignment within the route option.


People



Properties fall within this route at Glen Bernera, Glen More and Kinloch Hourn. Generally, it is anticipated there would be opportunities to minimise potential impacts to properties, albeit a pinch point does exist at Glen More which would require consideration at alignment stage.



Designations This route crosses through around 16 km of the Knoydart NSA with a further 2.5 km running along the boundary of the NSA.

The proposed steel structures would replace similar steel lattice towers through this section. However, the narrow valleys, steep slopes and complex topography, particularly around Kinloch Hourn, would result in difficulty in achieving an off-line alignment (including earthworks and construction access, once determined) which would not have greater impacts. It is likely that there would be a requirement to remove some native woodland to accommodate the new OHL.

Potential impacts are anticipated to the Special Qualities of the NSA ‘grand coastal and mountain scenery’ and ‘dramatic sea lochs’.

This route crosses around 11 km of the Kinlochhourn – Knoydart – Morar WLA with a further 12 km running along its boundary. The wild land value of this section is considered to be lower than the WLA generally due to features such as the existing OHL, the road to, and properties at Kinloch Hourn and rough all-terrain vehicle tracks which are present along some sections of the route. However, it does have a strong remote character and is considered to have an important role as a transitional landscape and journey into the wilder parts of the WLA. As the steel structures would replace steel lattice towers which are already present, the longer term impacts on wild land would be likely to be similar, although the difficulty to accommodate and construct the OHL in some areas may lead to different, offline alignments and a greater degree of earthworks which may increase the level of impact.

The eastern 11 km of this route crosses Moidart, Morar and Glen Sheil SLA along the northern shore of Loch Cuaich. Although replacing the existing OHL, this section of the route may be difficult to accommodate offline in some areas due to the location of the existing OHL and steep slopes potentially leading to it being higher up the hill and more prominent. However, the majority of the key aspects of the designation are anticipated to remain intact.

Landscape Character

Initially passing through the Coniferous Woodland Plantation LCT which is considered broadly accommodating of this type of development, and the Coastal Strath LCT which is considered to have some ability to accommodate the route, it then crosses areas of Rugged Massif, Rocky Moorland and Rocky Undulating Plateau and Interlocking Sweeping Peaks in the east, all considered of high sensitivity to this type of development. Whilst the presence of the existing OHL would reduce this sensitivity to some degree, the constrained, steep and complex topography would lead to difficulty in achieving an off-line alignment which would not have greater impact – particularly around Kinloch Hourn and between the Bealach Aoidhdailean and Loch Cuaich generally.

Interlocking sweeping peaks forms the most complex and sensitive landscape type through this area and it is potentially difficult to accommodate an offline alignment through this landscape without greater impact due to the narrow wooded gorge landscape through which the existing OHL passes. In places such as Kinloc Hourn, if the alignment were to diverge far from the existing OHL alignment, the impact would be notably increased due to increased prominence in key views, loss of landscape features and intrusion into remote areas.

SNH mapping indicates a moderate degree of wildness throughout this section, influenced by the existing OHL. However, whilst wildness characteristics are not strongly evident there is a strong sense of remoteness. Although the steel structures would replace steel lattice towers which are already present, the potential requirement to diverge from the existing alignment could lead to increased impacts on wild land.

Visual From Kylerhea and Otter Haven and properties and routes around Glenelg and Glen Bernera, the route would be likely to appear similar to the existing steel lattice tower OHL which it would replace. From Glen More the requirement to achieve a different crossing point across the glen and likely woodland removal may lead to a slightly increased visual impact for some properties along the minor road although the removal of the existing OHL may lead to a slight improvement in other views.

Passing through the mountain interior the route would be regularly visible from recreational and walking routes up through Gleann Beag, and from Kinloch Hourn and Arnisdale. Whilst this section would also replace existing steel lattice towers, the potential requirement to diverge from the existing alignment and slightly increased scale of the steel structures could lead to increased prominence or new views where views are currently not obtained. Removal of mature native woodland would also be required in some sections to accommodate a wayleave, leading to further potential visual impacts.

Further views would be obtained by travellers and recreational users on the minor road to Kinloch Hourn which is a popular route for tourists seeking a remote experience. Additional route and landform complexity between Kinloch Hourn and Loch Cuaich has the potential to increase the level of visual impact from this route, although there could also be a reduction in visibility in some limited areas.

There would also be potential for notably increased visual impact in views from properties, the car park and popular viewpoints at Kinloch Hourn depending on alignment, including likely tree felling.

Further to the east of this route alongside Loch Cuaich, there would be potential for this route to be fairly prominent due to a likely position higher up the steep side slope of the hills due to limited space. However, it is unlikely the route would intrude into the valued open views across Loch Cuaich towards the Knoydart mountains.

Forestry An extension to the existing wayleave required at Kyle Rhea, but generally limited removal of commercial forestry required for the remainder of this route. The route does however pass through an area identified for pinewood regeneration by Scottish Forestry. See also Habitats above with regard to woodland habitats.

Recreation Crossing several core paths and Scottish Hill Tracks. Potential exists for visual impacts on the amenity of these routes, particularly at the west end of the route where the OHL would cross the core path looping around Glas Bheinn twice, and where the route runs parallel to a longer distance hill track between Kinloch Hourn and Glen Elg. Potential impacts during construction also likely.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the landscape given route passes through a National Scenic Area and other areas of landscape importance. The RAG rating therefore reflects the potential for impact on some of these features, as noted above.

Proposals No notable developments identified near this route.

Route 4B – Glen More – Glen Shiel

Description:

This option follows a route through Glen More towards Shiel Bridge, with a variant option to the south of Sgurr Mhic Bharraich for greater flexibility in considering alignment options south of Shiel Bridge. The option then follows the glen and the A87 through Glen Shiel until it reaches Loch Cluanie.


Natural Heritage


Designations There are no designations for natural heritage along this route. It should be noted that the West Inverness-shire Lochs SPA component at Loch CLuanie is located at the very eastern extent of this route, after it has transitioned into Section 5. Potential constraints associated with this SPA are therefore discussed in Section 5 RAG tables.

Protected Species There is potential for European Protected Species such as otter and bats, along with protected species such as pine marten, red squirrels, water voles, badgers, and reptiles but further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, grassland on the lower areas, and areas of mixed and broadleaved woodland. These woodlands comprise native woodland, predominantly classified as upland birchwood, and ancient woodland. There is only a small area of semi-natural woodland along Glen More but some felling may be required. Using the northern route around Sgurr Mhic Barraich could require some felling within semi-natural woodland, although it might be avoidable with careful routing. The southern route would not require any felling. Along Glen Shiel there are several areas of semi-natural woodland most, if not all, of which can be avoided. There are areas of woodland noted on the AWI present along the route. Further survey work would be required to minimise potential impacts on these woodland areas in particular.

Ornithology There are no ornithological designations covering this route (see Designations above). Active golden eagle territories are present within the vicinity of the route. Potential collision risk is low assuming OHL can be routed appropriately. There will be potential of displacement from some parts of golden eagle territories for foraging, and also potential for the impacts of disturbance during construction, so sensitive timing and routeing will be required.

Previous information on the wintering whooper swan flock at Shiel Bridge will require investigation as there could be potential for collision and construction disturbance.

Hydrology / Geology

Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route would pass through the Glen More Geological Conservation Review (GCR), and potentially the Sgurr na Ciste Duibhe GCR. It is likely that some structures would be routed through the Glen More GCR.

Priority peatland mapping suggests that there are sections of Class 2 (strong likelihood of deep peat and priority peatland habitats) at intervals throughout this section and a section of Class 1 (strong likelihood of deep peat and priority peatland habitats) along the River Cluanie. Peat probing to inform the final alignment may be required.

Glenmore River and River Shiel (and associated tributaries) running adjacent to route for most of its length. Pollution risk will need to be considered.

Designations Glen Shiel Inventory Historic Battlefield Site (which includes a Scheduled Monument) is crossed by the route. This is the site of a battle in 1715; the last invasion of Britain by foreign troops. Battlefields are a fragile and finite resource, vulnerable to a range of impacts that can diminish their heritage value and archaeological potential.

There is also a cluster of listed buildings and a Scheduled Monument (Cill Fhearchair Standing Stone) within the route option at Invershiel / Shiel Bridge. The listed buildings have localised settings and can easily be avoided. The Scheduled Standing Stone can be easily avoided but consideration would need to be given to the potential for impact on its setting.


There are clusters of non-designated heritage assets recorded in the Historic Environment Record along and within the route option. These include two depopulated townships within Glen More, and post-medieval farmsteads and other remains along Glen Shiel and around Cluanie Inn.


People



Properties along Glen More and at Shiel Bridge and a small number of properties within Glen Shiel fall within this route. Particular care must be taken to avoid passing close to some of these properties.



Designations This route crosses around 10 km of the Kintail NSA from the top of the Ratagan Pass to the Glen Shiel Battlefield site. The route would introduce a new feature to Glen Shiel and would be likely to be prominent through the glen with potential impacts to the Special Qualities ‘drama epitomising the West Highland scene’ and ‘remote and wild interior’. The view from the Mam Ratagan towards the Five Sisters of Kintail is recognised as a Special Quality of the NSA and there is the potential for the steel structures to intrude into this view depending on alignment. The historic importance of the Glen Shiel Battlefield is also noted to contribute towards the Special Qualities of the NSA.

Following the A87 this route follows the narrow corridor between the Central Highlands WLA and Kinlochhourn – Knoydart – Morar WLA. Wild land characteristics are generally low through this section due to the influence of the busy A87 and areas of farmland and forestry. However, given the height of the proposed structures there is potential to increase the influence of this communication corridor on more remote areas of the interior.

The route crosses around 8 km of the Moidart, Morar and Glen Shiel SLA. Steel structures would form a new feature to this part of the SLA and could be prominent and detracting in views towards mountains from some areas depending on alignment, potentially affecting aspects of the Special Quality ‘distinctive west Highland composition’ which includes its role as an access point and setting to Glen Shiel and Kintail.

Character This route would result in direct impacts to the Coniferous Woodland, Coastal Strath, Rugged Massif and Interlocking Sweeping Peaks LCTs.

Coniferous Woodland Plantation LCT is usually considered broadly accommodating of this type of development, although the steep slopes and valued views associated with the Mam Ratagan could lead to difficulties in accommodating and constructing the steel structures without significant effect.

The small scale patterns of the Coastal Strath LCT along Glen More and Glen Shiel, and the remote upland characteristics of the Rugged Massif and Interlocking Sweeping Peaks LCTs are sensitive to development of the scale proposed and the steel structures could appear potentially dominating through this landscape, intruding into valued mountain views and affecting the sense of remoteness experienced in some areas away from the road.

SNH wildness mapping indicates a low degree of wildness for this route due to the influence of the busy A87 corridor and buildings, forestry and agricultural areas within the glens. Moderate wildness is shown only for the elevated section between Glen More and Loch Duich. However, the character does display some remote characteristics in some areas and the height of the proposed steel structures could lead to a wider influence of development on adjacent landscapes with higher wildness characteristics.

Visual From Kylerhea and Otter Haven, the route would be likely to appear similar to the existing steel lattice tower OHL which it would replace. However, steel structures would be likely to form prominent new features in views from properties and the minor road ascending Glen More.

There is the potential for steel structures along this route to appear within valued elevated views of the Kintail mountains from the road and viewpoints over the Ratagan pass south of Shiel Bridge depending on alignment.

From Shiel Bridge, a route and wayleave would be likely to be visible from properties and tourist sites as it rises up towards the Ratagan pass. Potential views would also be obtained by receptors as the route passes south of Ratagan and Shiel Bridge including from a camping site and as it crosses a walking route which provides access to mountain climbing routes.

Along Glen Shiel steel structures would be potentially prominent in views from a small number of properties depending on alignment with possible cut and fill and access requirements also potentially prominent.

There would also be views from the A87 throughout Gen Shiel, which is a popular tourist route and the primary road to Skye, This also applies to associated parking areas and viewpoints and to the eastern end of the route and to views from the remote Cluanie Inn.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.1 and 5.3) near Shiel Bridge.

Forestry Potential for some removal of forestry required as the OHL is routed through Glen More towards Shiel Bridge, and at Mam Ratagan. Further removal of woodland anticipated through Glen Shiel, particularly if routed on the north side of the road. The route also passes through an area identified for pinewood regeneration.

Recreation Running parallel to minor roads and walking routes in Glen More but potential impacts on recreational enjoyment considered low. Depending on alignment the route has the potential to appear in key views from the Ratagan Pass which has the potential to detract slightly from the appeal of this viewpoint. There is also potential for physical impact to a campsite near Shiel Bridge, although potentially avoidable.

Running parallel to the A87 along Glen Shiel the route has the potential to be distracting in views.

Route 4C – North of Loch Alsh and Loch Duich

Description:

This option would include a connection from Route Options 3A or 3C, to the north of Loch Alsh and Loch Duich, and would include the eastern section of Route Option 4B at Shiel Bridge.


Natural Heritage


Designations The route runs to the south of Coille Mhor SAC / SSSI, designated for western acidic oak woodland. It is anticipated that potential impacts on this designated site could be avoided, or kept to a minimum. The route would also be required to cross Lochs Duich, Long and Alsh SAC / NCMPA, an area of sheltered reefs and flame shell beds.


There is potential for European Protected Species such as otter and bats, and other protected species such as pine marten, red squirrel, badger and reptiles, but further survey work would be required to determine their presence along the route. It is anticipated that opportunities would exist to minimise potential impacts on protected species, although RAG rating reflects potential for impacts on woodland habitats (see Habitats below).

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, grassland on the lower areas, and areas of mixed and broadleaved woodland. These woodlands comprise native woodland, predominantly classified as upland birchwood, and ancient woodland. Some of the woodlands (e.g. Balmacara Estate) are moderately rich in lichen and bryophytes.

Ornithology There are two occupied golden eagle territories within the general vicinity of the route option, but it is not anticipated that this route would result in much loss of territory given proximity to A87 and settlements. Black throated and red throated diver species will likely be flying over this area from the hills above.

Further work would be required to determine potential impacts and appropriate mitigation measures at loch / waterway crossing points as these could be frequently used by bird species. A small flock of whooper swan are noted as overwintering at the head of the loch around Shiel bridge and this will require further investigation.

Hydrology / Geology

This route crosses over a surface water drinking protection zone near Auchtertyre / Nostie. Isolated properties may maintain private water supplies. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

This route would pass to the north of Ard Hill and Avernish GCR / Geological SSSI, and would run adjacent and to the east of Dornie GCR. It is anticipated that potential impacts on all of these sites of geological importance could be avoided. Priority peatland mapping suggests that the route generally avoids areas of deeper peat. There are however areas of Class 2 (strong likelihood of deep peat and priority peatland habitats) on higher ground to the north east of Kyle of Lochalsh and to the east of Dornie. Peat probing to inform the final alignment may be required.

Numerous watercourse crossings to consider throughout route. Crossing of Loch Long and the River Croe would require further and detailed consideration.

Cultural Heritage


Designations There are two Scheduled Monuments within the route option: St Dubhthach’s Church and Burial Ground (near Morvich) and Cill Fhearchair Standing Stone (Shiel Bridge). there are others outside but close to the route option, including: Castle Moyle (on the shore of Loch Alsh); Eilean Donan Castle, at Dornie; and Dunan Diarmid Dun, at the head of Loch Duich. Those within the route can be avoided. Consideration would need to be given to impacts on the settings of those both within and close to the route option.

There are also numerous listed buildings (categories B and C) within the route; all of which can be easily avoided, but where consideration would need to be given to potential impacts on their settings.

The route option also runs directly to the north side of Lochalsh Woodland Walks Garden and Designed Landscape (owned by the National Trust for Scotland) and part of the wider Balmacara Estate. Consideration for potential adverse impacts on its setting would need to be taken into account during the design.


There is a high number of non-designated heritage assets recorded in the Historic Environment Record along and within the route option. These include a cluster around Kyle of Lochalsh, at the western end of the route option, another around Dornie, and a further group around Invershiel/Shiel Bridge. These include assets of prehistoric date and medieval/post-medieval remains.


People



Properties at Kyleakin and Kyle of Lochalsh fall within this route as well as a number of properties along the northern shore of Loch Alsh and Loch Duich. Careful routeing and alignment would be required to minimise impacts.



Designations This route passes close to the Lochalsh Woodland Walks GDL. There is the potential for indirect impact depending on the alignment, although there may be opportunity to screen the OHL with trees.

The route also crosses through the Kintail NSA, from Dornie to Shiel Bridge and beyond to the Glen Shiel Battlefield. The presence of steel structures along the coastline of this route which is considered to contribute highly to the value of the designation would be likely to affect some of the Special Qualities such as the ‘inland Coast of Loch Duich’, ‘drama epitomising the West Highland scene’ and ‘features and landscapes of historical significance’ such as Kyleakin and Lochalsh Woodland designed landscapes and the setting of Eilean Donan Castle.

This route would also pass through approximately 2 km of the Kyle – Plockton Special Landscape Area. The crossing of Kyle Rhea and routing constraints around Kyle of Lochalsh would be likely to result in some impact on the coastal qualities of this SLA and its appreciation from areas such as Plock of Kyle.

The route also runs adjacent to the Central Highlands WLA. Wild land characteristics are generally low through this section due to the influence of the busy A87 and areas of farmland and forestry. However, the height of the proposed structures may result in some indirect influence into areas of greater wildness.

Character The predominant LCT crossed by this route option is the Rugged Massif LCT. Its exposed sense of place and large-scale landscape features are highly sensitive to the introduction of this type of development. The route would border areas of Rocky Moorland and Rocky Undulating Plateau which is also sensitive to the introduction of new elements due to its remote landscape character and sense of openness.

The route would also pass through some areas of Coniferous Woodland Plantation LCT at Balmacara and Inverinate which is considered broadly accommodating of this type of development. There is also the potential for the route to pass through areas of Linear Crofting, Harbour Settlement and Coastal Strath LCTs which have varying ability to accommodate this type of development depending on alignment.

Steel structures along the coastal part of this route would be likely to be frequently prominent and often distracting, particularly in areas such as Dornie and Shiel Bridge where they would be likely to be close to the coastline and intruding into mountain views.

SNH mapping indicates a low to moderate degree of wildness throughout this section. Whilst existing infrastructure around the coast limits wildness, some areas of Glen Shiel have a greater sense of remoteness. The height of the proposed steel structures has potential to influence some areas away from the roads where this sense of remoteness may be stronger.

It should also be noted that as this route would join Route Option 4B, the potential direct and indirect landscape impacts on Glen Shiel would not be avoided (see Route Option 4B).

Visual There would be likely views of this route from properties, routes and recreational areas in and around Kyleakin and Kyle of Lochalsh. Potential views would also be obtained from other coastal villages along the shores of Kyle of Lochalsh and Loch Duich and from the A87 and other minor routes. The proposed steel structures would be likely to be prominent in some of these views, although the route would generally avoid the valued coastal views.

From some sections of this route, woodland, forestry and topography may help to screen the line from the A87. Potential impacts may include valued mountain views from parking viewpoints and walking routes commencing at the road.

It should also be noted that as this route would join Route Option 4B, the potential direct and indirect visual impacts on Glen Shiel would not be avoided (see Route Option 4B).

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. The exceptions to this include grassland at Balmacara (4.2) and Morvich (4.1), and sections of improved grassland (5.1 and 5.3) between Balmacara and Dornie, and at Morvich. Opportunities to minimise potential impacts on these areas should exist but would require further consideration.

Forestry Areas of forestry and woodland throughout the route. It is anticipated that those areas of woodland on the lower slopes, adjacent to the A87, would be avoided. Careful consideration of alignment options to minimise potential impacts on forestry and woodland would be required.

Recreation Following the main tourist route to Skye, and passing points of interest for tourists such as Eilean Donan Castle, this is a highly trafficked tourist area. The route would cross several core paths, particularly at Balmacara and Plock of Kyle which are areas visited frequently by tourist and locals, as well as long distance walking routes. The area is well served with tourist accommodation, services, activities and points of interest.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the landscape given route passes through a National Scenic Area and other areas of landscape importance, as well as cultural heritage and sites of national importance and potential impacts on the natural environment. The RAG rating therefore reflects the potential for impact on some of these features, as noted above.

Proposals This route intersects with a number of proposals including Altanavaig Quarry at Kyleakin, whereby an application has been lodged for the storage of Liquified Natural Gas (20/00699/HSC). Intersects several development plans at Kyle of Lochalsh, including mixed use (housing, community, business / tourism), housing developments and industry.

Residential development of 44 housing units at Auchteryre (19/01443/PIP).

Section 5 – Loch Cuaich / Loch Cluanie – Invergarry / Glen Moriston


Description:

This option follows the route of the existing steel lattice OHL from Quoich Dam to Invergarry. It is routed to the north of the minor road to Kinloch Hourn and Loch Garry.


Natural Heritage


Designations This route option borders the West Inverness-shire lochs SPA / SSSI, which is classified for 6.6 pairs (on average) of black-throated divers and 7.8 pairs (on average) of common scoter. Black-throated divers and common scoters may fly between the composite lochs of the SPA / SSSI and could be vulnerable to collision from OHLs between the lochs, as well as disturbance. Following existing transmission OHL locations will minimise any 'novel' impact of OHL (see Ornithology below).

Protected Species There is the potential for EPS such as otter and bats, along with other protected species such as red squirrel, water vole, pine marten, badger and reptile species. Further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands and grassland on the lower areas, as well as forestry plantations. Some of the plantation forestry comprises native woodland, particularly to the north of Loch Garry. There is an area of native pine regeneration at Coille Mhorgil which, depending on the alignment taken, could be avoided. Along Loch Garry felling within semi-natural woodland is unavoidable. Woodland listed on the Ancient Woodland Inventory (AWI) is present. Further survey work would be required to minimise potential impacts on these woodland areas in particular.

Ornithology The route is adjacent to the West Inverness-shire Lochs SPA / SSSI, following the route of the existing OHL, and hence lies between these lochs and the other lochs within the SPA / SSSI. There is some potential collision risk for birds flying between these lochs, although as the route is predominantly through forestry, the risk will be lower. The route is also parallel to a potential flight route to the sea (west) for the SPA / SSSI interest species. Field surveys took place in 2016 and 2018 at three focal vantage points on parts of this route for diver and scoter flights. In addition, further survey effort was undertaken in 2018 in relation to the Quoich to Aberchalder OHL comprising breeding wader, black grouse and scarce breeding bird surveys. A focal vantage point for golden eagle flights was also completed during 2018 surveys.

In relation to the SPA species both diver and scoter species use the waterbodies alongside the route and flights were observed along the waterbodies, but none crossing between them. The risk of collision has been derived as low to both these species. There is possible disturbance due to construction which can be mitigated through timing.

There are red- throated diver breeding lochs in the wider area, with potential for collision, displacement and construction disturbance, which may require mitigation.

One active golden eagle territory centre lies within the vicinity of the route, there will therefore be potential for collision and displacement, which can be minimised by keeping the new OHL along the route of the existing OHL and within the plantation forest. Black grouse, greenshank and osprey also nest along the route and potential disturbance due to construction activities may occur and will require mitigation if nests are located within possible disturbance distances.

Hydrology / Geology

This route crosses over surface water drinking protection zones between Loch Loyne and Loch Garry, and northwest of Invergarry, and may compromise their quality and / or quantity.

This route passes through the Quoich Spillway GCR, but no impacts on this site are anticipated.

Isolated properties are likely to utilise private water supply sources. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.

Priority peatland mapping suggests that there are sections of Class 1 and 2 (strong likelihood of deep peat and priority peatland habitats) at the western end of this section from Quoich Dam to Tomdoun. Peat probing may be required to inform the final alignment.

Number of fast flowing watercourses to cross and pollution risk will be a concern.

Cultural Heritage


Designations One category B listed building lies within the route option: hydroelectric power station infrastructure at the east end of Loch Quoich, industrial buildings of 1950s date, which should exist reasonably harmoniously with modern features of electricity generation and transmission.

There are other listed buildings within Invergarry but there are no Scheduled Monuments, or other designated heritage assets, close to the route that have settings that are sensitive to indirect impacts.


There are few non-designated heritage assets recorded in the Historic Environment Record along this route option and little by way of constraint to routing and alignment within the route option.

People



Properties along Glen Garry, at Tomdoun and Poulary and at Munerigie and Achadh Luachrach are within this route although there are likely to be opportunities to avoid these properties.

Landscape


Designations Around 2.5 km of western end of the route falls within Moidart, Morar and Glen Shiel SLA. This comprises only the edge of the SLA in an area where other OHLs are already prominent. The proposed development would replace the existing steel lattice OHL through this landscape. Whilst this would be required to follow a different off-line alignment it is not anticipated to lead to an increased level of impact on the Special Qualities of the SLA.

The very western end of the route falls within Kinlochourn – Moidart – Morar WLA. This is an area of lesser wild characteristics due to the presence of the Quoich dam, minor road and existing OHLs. However, it does have valued remote qualities as an approach to the areas of greater wildness. However, as the proposed development would replace existing steel lattice towers within this landscape would not be expected to notably increase the impact on the WLA.

G


Character This route mostly follows the transition between Broad Forested Strath LCT and Rocky Moorland LCT, usually providing a good opportunity to route linear features, although the requirement to find an alignment away from the existing alignment may be restrictive in some locations leading to a potentially increased level of impact. There would also be a requirement to broaden or create a new wayleave through areas of forest and woodland alongside Loch Garry which has the potential to increase the landscape impact in some areas. The proposed steel structures may appear slightly larger and more robust than the existing steel lattice towers which may also increase their prominence within the landscape. However, this landscape is generally considered to be broadly accommodating of a replacement OHL.

SNH mapping indicates this route to have a low degree of wildness. Any impact on wildness is anticipated to be limited to the western end where there is the potential for a revised alignment and larger structures to be slightly more prominent in the approach to areas of greater wildness characteristics.

Visual This route would be potentially visible from a number of properties and a minor road along Glen Garry, appearing within rear views for most properties with the potential to be occasionally hidden by forestry and woodland. However, a new or increased wayleave may be visible from some areas. The new steel structures would replace existing steel lattice towers in the view but the potentially more robust and heavier structures have the potential to be more prominent in the view.

There would be potential views of the route running alongside the A87, from some tourist viewpoints on the road and also as it crossed the road. Although this would replace the existing steel lattice OHL the potentially heavier construction type and potentially higher position up the hill may result in it being more prominent. Rural properties to the north of this road at Munerigie and Achadh Luachrach may also obtain views of the route although depending on the final alignment, this may be offset to some degree by the removal of the existing steel lattice OHL from this view.

The requirement to route this option adjacent to the existing route could lead to increased impacts in places due to restricted space leading to steel structures being either higher uphill or closer to properties.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.3) to the north of Loch Garry.

Forestry Felling required to the north of Loch Garry, albeit there has been some felling in this area recently. An extension to the existing wayleave may be required.

Recreation Running along Glen Garry, this route would be parallel to the minor road and in the vicinity of some Scottish Hill Tracks but potential impacts to recreational amenity considered negligible. No notable impacts to recreation are anticipated.

Route 5B – South Glen Garry

Description:

This option is largely routed through forestry plantation in Glen Garry, to the south of Loch Garry. The route is located to take advantage of the forested valley reducing potential visibility of the OHL and wayleaves from Glen Garry. An additional connection point to Route Option 5A at Poulary is included to allow additional flexibility for alignment options.


Natural Heritage


Designations This route option borders the West Inverness-shire lochs SPA, and crosses it at Poulary, which is classified for 6.6 pairs (on average) of black-throated divers and 7.8 pairs (on average) of common scoter. Black-throated divers and common scoters may fly between the composite lochs of the SPA (SSSIs) and so be vulnerable to collision from OHLs between the lochs. This route would create a new feature to the south of Loch Garry. See Ornithology below.

The route also borders the Garry Falls SSSI at the eastern end of the route, although potential impacts on this site would be avoidable.

Protected Species There is the potential for EPS such as otter and bats, along with other protected species such as red squirrel, pine marten, badger, water vole and reptiles. Further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly forestry plantation. Some of the plantation forestry comprises native woodland, particularly to the south of Loch Garry. Some areas of woodland are present on the AWI. At Coille Mhorgil there are small areas of semi-natural woodland that are avoidable by routing to the south of the river. From near Garrygualach the route crosses the Glen Garry Caledonian Pine buffer zone for about 14 km. This area is also part of a Large Scale Ecosystem Restoration management project which aims to improve the condition of native woodland habitats. For the first 8 km it is possible to avoid felling within the remnant pinewood and associated regeneration zone. For the next 5 km the route cannot avoid some of the area within the regeneration zone and felling of some remnant pines may be unavoidable. Felling of other semi-natural woodland within this length of the route may also be unavoidable.

Further survey work would be required to minimise potential impacts on these woodland areas in particular.

Ornithology This route is adjacent to the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter), and crosses it at Poulary, on the south shore of Loch Garry and associated waterbodies, at the southern edge of the SPA. Due to its location to the south of the SPA flights by the SPA qualifying species are considered less likely to cross the route, although the potential still exists. This route is also sited through forestry plantation which should also reduce risk of collision for these species.

No field surveys took place in 2016 for diver and scoter flights although both species were confirmed as breeding on the waterbodies during 2016 and 2018. One focal vantage point was sited near Poulary in 2018.

There are red-throated diver potential breeding lochs in the wider area, with potential for collision, displacement and construction disturbance, which may require mitigation.

Two category C listed buildings (a house and a bridge) within route option.

There are other listed buildings within Invergarry but there are no Scheduled Monuments, or other designated heritage assets, close to the route that have settings that are sensitive to indirect impacts.


There are few non-designated heritage assets recorded in the Historic Environment Record along this route option and little by way of constraint to routing and alignment within the route option.

People



Properties at Kingie, Poulary, Greenfield and Whitebridge fall within this route. These properties are likely to be avoidable depending on the alignment chosen.

Landscape


Designations Around 2 km of the western end of the route falls within Moidart, Morar and Glen Shiel SLA. This comprises only the edge of the SLA in an area where other OHLs are already prominent. The proposed development would replace the existing steel lattice OHL through this landscape. Whilst this would be required to follow a different off-line alignment it is not anticipated to lead to an increased level of impact on the Special Qualities of the SLA.

The very western end of the route falls within Kinlochourn – Moidart – Morar WLA. This is an area of lesser wild characteristics due to the presence of the Quoich dam, minor road and existing OHLs. However, it does have valued remote qualities as an approach to the areas of greater wildness. However, as the proposed development would replace existing steel lattice towers within this landscape it would not be expected to notably increase the impact on the WLA.

Parts of the western end of this route also run adjacent to a separate part of this WLA to the south. Within the forested context this is considered unlikely to lead to a notable wild land impact but depending on the alignment, the height and man-made qualities of the structures could have some minor influence on the wild characteristics around the edge.

Character The majority of the route lies within the Broad Forested Strath LCT with the western end following the transition into the Rocky Moorland LCT, usually providing a good opportunity to route linear features of this type. Within the Broad Forested Strath LCT, the route follows a low lying route through commercial forestry plantation with good opportunity to accommodate this type of development.

In some areas, pockets of native woodland and Caledonian Pine could be affected leading to localised loss of landscape features.

There may also be potential localised impacts to smaller scale settled landscapes in Glen Garry at east and west ends of the route.

SNH mapping indicates a relatively low degree of wildness for this route and therefore no notable impact on wildness is anticipated.

The RAG Rating applied relates to the potential loss of Caledonian Pine and potential impacts to local landscapes at the eastern end of Loch Garry.

Visual Potential visibility from a few estate properties on the south side of Loch Garry and around Loch Poulary. There may also be views of steel structures and the wayleave from properties, the Glen Garry minor road and elevated vantage points on the A87 on the northern side of Glen Garry. However, a sensitively aligned route could be achieved behind landform and existing felling patterns which would help disguise the route.

There may also be views of the steel structures from the eastern end of Loch Garry including potential views from small number properties and recreational routes near Whitebridge.

There are a number of recreational routes through forest on the south side of Loch Garry which may gain views although the presence of forest could reduce visibility and reduces visual sensitivity of these routes.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.3) in limited areas to the south of Loch Garry.

Forestry Extensive removal of woodland required along route through forestry to the south of Loch Garry (see also habitats description above).

Recreation This route would cross and run parallel to two Scottish Hill Tracks and a core path within the forest but potential impacts to recreational amenity of these routes would be limited.

At Whitebridge, white-water rafting and canoeing take place and there is a parking and picnic area with woodland walking trails. Felling for a wayleave in this area has the potential to affect recreational enjoyment of these activities. Rating reflects potential impacts at Whitebridge.

There is also the potential for minor physical impacts and indirect visual impacts to a caravan park which could affect recreational amenity.

Route 5C – Loch Cluanie – Glen Moriston

Description:

Following a route along Loch Cluanie and Glen Moriston. This option is routed to the north of Loch Cluanie. Near the A87 / A887 junction, it would cross the River Moriston and would be routed on the south side of Glen Moriston before connecting into the Beauly – Denny wayleave corridor (6B).


Natural Heritage


Designations This route option borders the West Inverness-shire lochs SPA, which is classified for 6.6 pairs (on average) of black-throated divers and 7.8 pairs (on average) of common scoter. Black-throated divers and common scoters may fly between the composite lochs of the SPA (SSSIs) and so be vulnerable to collision from OHLs between the lochs. This route would create a new feature to the north of Loch Cluanie. See Ornithology below.

The route would also cross the River Moriston SAC, the qualifying features of which are Atlantic salmon and freshwater pearl mussel. Potential direct and indirect impacts on this designation should be avoidable.

Protected Species This route would cross, and be in the vicinity of, the River Moriston SAC which is designated for Atlantic salmon and freshwater pearl mussel. Potential direct and indirect impacts on this designation should be avoidable.

Other potential EPS along the route could be otter and bats, as well as WCA species such as water vole, red squirrel, badger, pine marten and reptiles. Further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, grassland on the lower areas, and areas of native woodland. There are also areas of commercial forestry, particularly in Glen Moriston. At the east end of Loch Cluanie there are areas of native woodland regeneration, which could be avoided. East of Loch Cluanie the route crosses the Bunloyne Caledonian Pine buffer zone and at the east end of the route in Glen Moriston crosses the Achlain and the Dundreggan Caledonian Pine buffer zones. The pinewood remnants in these areas are avoidable. Out with these buffer zones, felling within areas of semi-natural woodland in Glen Moriston is unavoidable. Areas of woodland to the east of the route are present on the AWI.

Further survey work would be required to minimise potential impacts on these woodland areas in particular.

Ornithology Route is adjacent to the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter) as it follows the main road on the north shore of Loch Cluanie and associated waterbodies, at the northern edge of the SPA, then along Glen Moriston. Due to its location to the north of the main SPA lochs, flights by the SPA interest are less likely to cross the route, but the potential still exists. Also due to the terrain this possible route to the sea is probably less attractive to the SPA interest.

Field surveys took place in 2016 on parts of this route for diver and scoter flights with two focal vantage points on Loch Cluanie. No flights were seen crossing between the SPA waterbodies or leaving the Loch for the sea. Both species use the waterbodies alongside the route with black-throated diver confirmed as breeding in 2016.

There are red- throated diver potential breeding lochs in the wider area, with potential for collision, displacement and construction disturbance, which may require mitigation.

Black grouse display (lek) areas within the route buffer, potential for collision, displacement and construction disturbance, some mitigation during construction could be considered.

Cultural Heritage


Designations Proposed route option intersects with Fort Augustus-Bernera military road Scheduled Monument, Tir nan Og, cairn Scheduled Monument, and three listed buildings, two of which are bridges.

Opportunities exist to ensure that all can be avoided. Sensitive routing will likely limit setting impacts is within route option. Consideration will need to be given to the setting of Tir nan Og cairn in particular.

Balnacarn township Scheduled Monument lies north of route option but sufficiently far that its setting unlikely to be significantly adversely affected.

One A-listed building, a bridge, at north end, with potential for setting impacts. Sensitive siting of alignment and towers would limit indirect (setting) impacts.


Route of Fort Augustus-Bernera military road runs through Glen Shiel / Glen Morriston. Features associated with road present within route option.

There are other non-designated heritage assets recorded in the Historic Environment Record elsewhere along this route option but little by way of constraint to routing an alignment.

Consideration would need to be given to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development, it is considered that opportunities to minimise impacts would exist.

Designations Approximately 11 km of the western portion of this route passes through the Moidart – Morar – Glen Shiel SLA. Steel structures would potentially affect views across Loch Cluanie and towards mountains and mouths of glens with the potential to affect the Special Quality ‘distinctive west Highland composition’. The value of this area is already noted to be reduced to some extent by reservoir drawdown but is a section which is popularly enjoyed due to the presence of the A87. Opportunities exist to accommodate the route within areas of young forest planting and landform towards the east of the designation but it would have a potentially greater influence at the western end where steep slopes may constrain the alignment.

The route runs along the periphery of the Central Highlands WLA. Alongside the reservoir and busy A87 road, it follows a route with reduced wildness and away from the core of the WLA although the height of the structures could have some influence on wildness experienced in some of the remote side-glens.

Character The western part of this route passes through the Rugged Massif LCT, considered to be of generally high sensitivity to this type of development, whilst the eastern part passes through the Wooded Glen LCT considered to have greater ability to accommodate a route.

Within the Rugged Massif LCT, the route would introduce a new feature alongside Loch Cluanie, likely to affect views towards mountains, up glens and across the reservoir.

Through Glen Moriston within the Wooded Glen LCT, tree felling for a wayleave may be required. The glen is considered to have some ability to accommodate a route. However, there may be possible cumulative effect with other OHLs in this area.

Visual This route would be visible from a number properties on the north side of Glen Moriston with potential for views of a wayleave through the forest. There would also be likely views from Cluanie Lodge and the Cluanie Inn, and the A887 and A87 which are popular tourist routes, including from some parking and viewpoint areas. Some of these views would have the potential to be prominent. The route would also be potentially prominent from a number of reactional routes into the hills which commence from the A87.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with grassland (4.2) and sections of improved grassland (5.2 and 5.3) through Glen Moriston.

Forestry Removal of woodland likely, particularly through the commercial plantations of Glen Moriston.

Recreation Runs alongside A87. Potential visual impacts could detract from recreational enjoyment but not anticipated to affect popularity of this as a tourist route.

A small number of walking routes may be crossed by this route but this would not affect recreational amenity.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted, particularly in relation to potential impacts on the natural environment given the presence of features of international and national importance, and areas of landscape importance.

Route 5D – Loch Cluanie – Loch Loyne

Description:

Providing a connection between Glen Shiel and Glen Garry route options, this route follows the southern shore of Loch Loyne, tying in to Glen Garry via forestry at the east end of Loch Garry where it would combine with 5A or 5F, or potentially return back to Glen Moriston via 5E.


Natural Heritage


Designations This route option borders the West Inverness-shire Lochs SPA, which is classified for 6.6 pairs (on average) of black-throated divers and 7.8 pairs (on average) of common scoter. Black-throated divers and common scoters may fly between the composite lochs of the SPA (SSSIs) and so be vulnerable to collision from OHLs between the lochs. This route would create a new feature to the south of Loch Cluanie and north of Loch Loyne, and would bisect the main SPA lochs. A precautionary approach has been taken when applying this rating, which is based on limited survey data. As limited survey data has been collected over this section a re-evaluation of this rating would be required if further surveys were completed.

Protected Species There is the potential for European Protected Species such as otter, and other protected species such as water vole, badger and reptiles to be present along the route. There is also the potential for pine marten and red squirrel to be present in the woodland sections of the route. Further survey work would be required to determine their presence along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland and peatlands, with some areas of native woodland. South of Cluanie Lodge the area of Scot’s pine regeneration can be avoided, as can the areas of regeneration within the Glen Loyne Caledonian Pine buffer zone. A further area of woodland regeneration along Loch Loyne would have to be crossed and might be difficult to avoid. Areas of woodland recorded on the AWI are present along the route,

Further survey work would be required to minimise potential impacts on these habitats.

Ornithology This route lies between the main lochs within the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter). It potentially intersects flight routes between these lochs and also flight routes to the sea by the SPA interest.

There are red- throated diver potential breeding lochs in the wider area, with potential for collision, displacement and construction disturbance. A precautionary approach has been taken when applying this rating, which is based on limited survey data from 2016 and 2018, although both SPA qualifying species were observed as breeding on the SPA component lochs in 2016 and 2018..

Two active golden eagle territory centres are less than 1km from the potential OHL route and would require careful siting of the OHL to avoid collision risk and displacement impacts. Potential marking of the OHL should be considered.

At a minimum black grouse and greenshank also breed in the area and sensitive timing of construction activities may be required to avoid disturbance

Further surveys would be required.

Hydrology / Geology


Route unlikely to lie within water catchments to water supplies.

Priority peatland mapping suggests that there is Class 2 (strong likelihood of deep peat and priority peatland habitats) located along the length of this route. Peat probing may be required to inform the final alignment.

Cultural Heritage


Designations No designated heritage assets within or in vicinity of this route option.


A large number of non-designated heritage assets recorded in the Historic Environment Record along the route of the 'Old road to the Isles' from Tomdoun to Cluanie Inn. These are mostly associated with the road and include: bridges, culverts etc. Little else by way of constraint to routing an alignment within the route option.

Consideration would need to be given to avoid and minimise potential impacts to recorded heritage assets, especially direct impact on the Old Road. Also, potential for encountering unrecorded archaeological remains. Given the nature of development, it is considered that opportunities to minimise impacts would exist.

People



There are no properties in this route but properties would be present in the route combining with 5A through Glen Garry or 5E/5C, through Glen Moriston, although should be largely avoidable.

Landscape


Designations The western 6 km of this route passes through the Moidart – Morar – Glen Shiel SLA and would introduce a new feature. Intruding into landscapes on southern side of Loch Cluanie which have wilder character than the main glens (although shown to have limited wildness on SNH mapping) the steel structures would be likely to be prominent in a landscape where there are no similar features, thereby potentially affecting the Special Quality ‘distinctive west Highland composition’ which notes wildness as a contributory factor.

The route follows the edge of the Kinlochourn – Knoydart – Morar WLA. Although this area is shown to have limited wildness on SNH mapping due to the existing access track, steel structures along this route have the potential to appear prominently in the landscape and affect wild characteristics along this edge. However, this would have little influence on the main body of the WLA due to topography.

Character This route would have direct impact on the Rugged Massif LCT, passing into the Rocky Moorland LCT. Both LCTs are considered to be sensitive to this type of development although rocky moorland has potentially a greater degree of opportunity.

This route follows a rational route through the landscape but would result in the addition of new prominent vertical man-made features round the south shore of Loch Cluanie and along the shore of Loch Loyne which has little existing development. It may also detract from wildness characteristics as it crosses the hill from Loch Cluanie to Loch Loyne, although SNH mapping indicates a lower to moderate degree of existing wildness in these areas.

The route is considered easier to accommodate through forest in the Rocky Moorland LCT and moving into the Broad Forested Strath LCT at the eastern end of the route although would still introduce a new feature to these areas.

Visual There would be close and potentially prominent views of this route across Loch Cluanie from the A87, a popular tourist route to Skye, of the OHL rising over hill, and from the Cluanie Inn and Cluanie Lodge.

There would also be potential views from elevated viewpoints on the A87 above Loch Loyne although these would be more distant (at least 3 km) and seen in a context of forestry.

The route would be potentially prominent from recreational routes through hills west of Loch Loyne.

Combining with 5A through Glen Garry there would be potential views from properties and routes around Glen Garry as discussed for route 5A. Equally, if combined with 5E, there would be potential views from properties in Glen Moriston.

Land Use



Forestry Some removal of woodland required as the route connects with other route options (e.g. 5A or 5E).

Recreation This route runs parallel to a Scottish Hill Track at the west end of Loch Cluanie but the potential to affect recreational amenity of this route are potentially negligible.

Whilst the route may appear within views from parking areas and viewpoints on the A87 it would be very distant and potential impacts on the amenity of these areas are potentially negligible.

Route 5E – Glen Moriston – Loch Loyne

Description:

Providing a connection between the Glen Moriston and Glen Garry route options, following the shore of Loch Loyne. This option has the opportunity to connect either through forestry at Tomdoun (referred to below as the eastern route option) or via Glen Quoich (referred to below as the western route option), and the flexibility to take a higher or lower level route at Glen Moriston.


Natural Heritage


Designations This route lies between the main lochs within the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter). It potentially intersects flight routes between these lochs and also flight routes to the sea by the SPA interest. A precautionary approach has been taken when applying this rating, which is based on limited survey data. As limited survey data has been collected over this section a re-evaluation of this rating would be required if further surveys were completed.

The route runs close to River Moriston SAC (see Habitats below).

Protected Species Northern ends of route buffer are adjacent to the River Moriston SAC which is designated for Atlantic salmon and freshwater pearl mussel. Potential indirect impacts during construction, but anticipated that this could be avoided.

There is the potential for European Protected Species such as otter, along with other protected species such as water vole, badger and reptiles to be present along the route. The woodland areas have the potential to support pine marten and red squirrel.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, areas of native woodland and commercial forestry. The route crosses areas of regeneration within the Glen Loyne Caledonian Pine buffer zone and along Loch Loyne. There are areas of semi-natural woodland at Garrygualach that are avoidable with careful routing. Where the route continues east to join with 5C it crosses areas with remnant native pinewood along Loch Loyne and east of the Loch Loyne dam which may require some felling. At the first joining with 5C the route crosses the Bunloyne Caledonian Pine buffer zone, the remnant pinewood and regeneration zone are avoidable. At the alternative joining with 5C the route crosses the Achlain Caledonian Pine buffer zone, the remnant pinewood and regeneration zone are avoidable. Areas of woodland noted on the AWI are present.

Ornithology This route lies between the main lochs within the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter). It potentially intersects flight routes between these lochs and also flight routes to the sea by the SPA interest. Limited field surveys took place in 2016 on parts of this route for diver and scoter flights, and other limited survey work was carried out near to this route during 2018. Both species were noted as breeding on the SPA component lochs during 2016 and 2018. No SPA qualifying species were observed flying between the lochs or towards the sea, whilst red-throated divers were seen on two occasions crossing the proposed route.

There are red- throated diver breeding lochs in the wider area, with potential for collision, displacement and construction disturbance so mitigation may be required.

Two active golden eagle territory centres within the vicinity of the route and would require careful siting of the OHL to avoid collision risk and displacement impacts.

At a minimum black grouse and greenshank also breed in the area and sensitive timing of construction activities may be required to avoid disturbance.

A precautionary approach has been taken when applying this rating, which is based on limited survey data from 2016 and 2018.


Hydrology / Geology

This route crosses in close proximity to a surface water drinking protection zone between Loch Loyne and Loch Garry. Isolated properties likely to maintain private water supply sources. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.


Priority peatland mapping suggests that there is Class 2 (strong likelihood of deep peat and priority peatland habitats) located along long sections of this route. Peat probing to inform the final alignment may be required.

Pollution risk at River Moriston SAC which will require mitigation as part of the detailed design.

Cultural Heritage


Designations No designated heritage assets within or in vicinity of this route option with settings sensitive to potential impacts.


Very few non-designated heritage assets recorded in the Historic Environment Record, partly reflecting upland nature of ground and partly lack of systematic survey.

Little by way of constraint to routing an alignment within the route option.

Consideration would need to be given to avoid and minimise potential impacts to recorded heritage. Limited Potential for encountering unrecorded archaeological remains. Given the nature of development, opportunities to minimise impacts would exist.

People



Properties along Glen Garry, at Tomdoun and Poulary are present within this route but it is likely to be possible to avoid passing close to these. As the route would join with route 5C through Glen Moriston, a few properties in this area would also be within or close to the route but are likely to be avoidable.

Designations The western option to Loch Cuaich passes through the Moidart – Morar – Glen Shiel SLA, passing through a deep, open valley through centre of mountain where sections have little other infrastructure. This area also portrays a sense of wildness and is considered to contribute to the Special Quality and value of the SLA.

The western option to Loch Cuaich also passes through the Kinlochourn – Knoydart – Morar WLA. Existing tracks reduce wildness, particularly at Glen Quoich end but there is a stronger sense of wildness between Glen Quoich and Loch Loyne.

The proposed steel structures if routed through the western section would be prominent and likely to detract from the values of both the SLA and WLA.

Around 2 km of the eastern option where it combines with 5A falls within the SLA. This comprises only the edge of the SLA in an area where other OHLs are already prominent and would comprise a lesser impact as described for route 5A. The eastern option would therefore be preferred for landscape and visual reasons. Because this is the more likely route, the RAG rating reflects the eastern option. If the western option were found to be preferred for other reasons, this RAG rating would be Red.

(Eastern option

only)

Character This route would have a direct impact on the Wooded Glen LCT, and Rocky Moorland LCT which are both considered to have some opportunity to accommodate a development of this type. It would also directly affect the Rugged Massif LCT with the western option to Loch Cuaich affecting the Interlocking Sweeping Peaks LCT. Both these LCTs are considered to have greater sensitivity to a proposed route.

Through the Wooded Glen LCT in Glen Moriston, and Rocky Moorland LCT south of Loch Loyne, a wayleave would be required through forest and woodland. However, there is potential for this to be accommodated within the existing forest structure. Steel structures would be new and sometimes prominent elements in these landscapes but there is considered to be some capability to accommodate them as other vertical elements are present.

There would be a potential cumulative impact from other OHLs present in Glen Moriston.

Within the Rugged Massif LCT, locally steep slopes to the east of Loch Loyne may be slightly difficult to accommodate with the potential for the OHL to be more prominent.

Impacts on the Interlocking Sweeping Peaks LCT would be limited to the western option along southern shore of Loch Loyne to Glen Quoich. West of Loch Loyne this would detract from stronger wild land characteristics. The eastern option would be more easy to accommodate through the forested edge landscape where, although potentially slightly more prominent, it would replace existing steel lattice towers which are already present in the landscape.

The RAG rating given reflects the Glen Garry (eastern) option. A Red RAG Rating would result from potential impacts to the Interlocking Sweeping Peaks LCT to Glen Quoich/Loch Cuaich if the western option was chosen.

(Eastern option

only)

Visual The route would run alongside the A87 for a short section and would be required to cross the road. There would therefore be views of this route from a short section of the A87 , including from some viewpoint laybys, depending on alignment, and also the A887 through Glen Moriston. Views from properties within Glen Moriston would also be affected.

There would also be views from properties at Kingie, Tomdoun and Poulary, where the route combines with route 5A, if the eastern option were chosen. Although this would be offset by some degree by the removal of the existing OHL, there is the potential for the proposed steel structures to be more prominent in these views.

The western route option would also be visible and prominent for recreational users using walking routes, particularly along Glen Quoich, and from receptors on a Scottish Hill track along this route.

The RAG rating given reflects the anticipated visual impact for both options for this route.

Route 5F – Forestry Commission Alternative Route

Description:

This route option departs from the existing OHL (Route 5A) at Tomdoun, at the western end of Loch Garry, before rising uphill through forestry to cross the A87 below Mullach Coire Ardachaidh in an easterly direction. From here the route hugs the northern edges of the forestry plantations which border Glen Garry, but keeping below the hilltops, before re-joining the existing OHL (Route 6A).


Natural Heritage


Designations This route lies between the main lochs within the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter). It potentially intersects flight routes between these lochs and also flight routes to the sea by the SPA interest. See Ornithology below.

Hydrology / Geology

This route crosses over surface water drinking protection zones between Loch Loyne and Loch Garry, and northwest of Invergarry, and may compromise their quality and / or quantity. Isolated properties are likely to maintain private water supply sources. Catchments to any groundwater wells, springs and GWDTE are likely to be similar to surface catchments and impacts should be mitigated by appropriate design.


Priority peatland mapping suggests that there is Class 2 (strong likelihood of deep peat and priority peatland habitats) located along long sections of this route. Peat probing to inform the final alignment may be required.

People



Properties along Glen Garry, at Tomdoun and Poulary are present where this route combines with Route 5A but it is likely to be possible to avoid passing close to these.

Landscape


Designations This route would follow the route of 5A at its western end and the impacts on designations would therefore be similar.

Around 2 km of western end of the route falls within the edge of the Moidart, Morar and Glen Shiel SLA. The proposed development would replace the existing steel lattice OHL through this landscape and is not anticipated to lead to an increased level of impact on the Special Qualities of the SLA.

The very western end of the route falls within Kinlochourn – Moidart – Morar WLA. This is an area of lesser wild characteristics due to the presence of the Quoich dam, minor road and existing OHLs. However, it does have valued remote qualities as an approach to the areas of greater wildness. However, as the proposed development would replace existing steel lattice towers within this landscape it would not be expected to notably increase the impact on the WLA.

Character This route falls predominantly within the Rocky Moorland LCT and where it shares the same route as 5A, would fringe the edge of the Broad Forestry Strath LCT. These LCTs are considered to have some capability to accommodate this type of development although open slopes and high ground are more sensitive. Much of the route would follow the upper line of the forestry which is a reasonably rational route. However, in some areas where it would be required to cross high ground and steep slopes it has the potential to become a prominent feature on the ridgeline. Towards the western end, the route would be required to cross more open and elevated land and would be likely to be more prominent within the broad, elevated vistas which are a valued aspect of this landscape.

SNH mapping indicates this route to have moderate to low degree of wildness. As the route mostly follows the edges of existing forest plantation it is unlikely that it would affect any areas strongly displaying the attributes of wild land. However, the introduction of a new, vertical built feature may have wider indirect impact on some of the more elevated and open areas.

Visual To the north of the A87, this route option would be elevated above the road. It would be visible from parts of the road, potentially skylining along the ridgeline of the hills and may be occasionally a distracting feature in views. In some places this would combine with the turbines of the Beinneun wind farm. However, this route has the potential to be prominent in views from the A87 as it rounds the corner travelling west and views towards the western mountains are revealed. It could also be prominent from this short section of the road when travelling east but likely to be less intrusive in the view.

This route would be potentially visible from the rear of properties at Munerigie and Achadh-luachrach. There would also be likely to be views from properties along the south side of Glen Garry, (such as at Garrygualach and Greenfield). It would be likely to be hidden by forestry and woodland from properties on the north side of Glen Garry.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with sections of improved grassland (5.3) to the north of Loch Garry.

Forestry Felling required to the west of the A87 to create a new wayleave. The route would border forestry to the north of the A87 but anticipated that potential impacts along these areas of forestry could be avoided.

Recreation The only interaction with a recognised walking route occurs at the eastern end of this route at Inchnacardoch Forest, whereby the Scottish Hill Track between Fort Augustus and Invergarry would be crossed. Potential landscape and visual impacts at the crossing of the A87 is of relevance to the consideration of recreational impacts as this area is a popular stopping point for tourists. Although not an official parking area or view point, tourists are attracted to the open views to the west and the mini cairn display from which this route would be visible.

Section 6 – Invergarry / Glen Moriston – Fort Augustus


Description:

Following the route of the existing Fort William to Fort Augustus steel lattice OHL from Invergarry to Fort Augustus Substation. This option would be routed through Auchterawe.


Natural Heritage


Designations This route borders Loch Lundie, one of the main lochs within the West Inverness-shire Lochs SPA (classified for breeding black-throated diver and common scoter). It potentially intersects flight routes between these lochs and also flight routes to the sea by the SPA interest, although surveys from the Fort Augustus to Skye T project did not identify a potentially significant risk with a new wood pole OHL to the east of Loch Lundie, and survey effort in 2016 and 2018 confirmed this. Construction disturbance issues would need to be considered.

Protected Species There is the potential for European Protected Species such as bats and otter, along with other protected species such as water vole, badger, pine marten, red squirrel and reptiles along the route. Further survey work would be required to determine their presence along the route. Opportunities to minimise impacts anticipated.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, areas of native woodland and commercial forestry. Depending on routing all areas of semi-natural woodland along this route could be avoided by keeping to the north of the existing powerline. Areas of woodland on the Ancient Woodland Inventory (AWI) are present.

Further survey work would be required to minimise impacts on these habitats.

Ornithology This route follows exiting OHL which runs to the east of Loch Lundie at the eastern edge of the West Inverness-shire Lochs SPA then through forestry to Fort Augustus Substation at Auchterawe (see Designations above).

Black grouse are present with a known lek near Loch Lundie, therefore construction disturbance will require mitigation through sensitive timing.

Hydrology / Geology


This route crosses over a surface water drinking protection zone to the north-west of Invergarry. Properties at Auchterawe likely to be served by a private water supply(s). Catchment area to springs, wells and GWDTE likely to be similar to surface water catchment area.

Priority peatland mapping suggests that there is Class 2 (strong likelihood of deep peat and priority peatland habitats) located on moorland near Loch Lundie.

Cultural Heritage


Designations Torr Dhuin fort Scheduled Monument lies within route but can easily be avoided; sensitive siting of alignment and towers will limit impact on setting.

Route option passes close to the Caledonian Canal Scheduled Monument but setting unlikely to be significantly adversely affected. Potential impacts on setting would need to be given due consideration during the alignment stage, as canal is also an important tourist route.


Very few non-designated heritage assets recorded in the Historic Environment Record along route option and little by way of constraint to routing an alignment within the route option.

People



A number of properties at Auchterawe fall within this route and the potential for constraint is increased by the presence of existing electricity infrastructure.



Designations This route would not affect any designated or otherwise protected landscapes

Character This route would directly affect the Rocky Moorland LCT and the Broad Steep-sided Glen LCTs, both considered to have some degree of ability to accommodate a development of this type.

The route would follow an existing steel lattice tower line. Whilst this reduces the sensitivity of the landscapes involved, it would lead to potential for cumulative impacts and would increase the influence of overhead line development.

Through the Rocky Moorland LCT there would be potential cumulative impacts to the locally sensitive small scale landscapes around Loch Lundie due.

Within the Broad Steep-sided Glen LCT, the additional OHL would lead to cumulative impacts through the small scale settled and farmed landscapes of Auchterawe with the potential to be locally dominating in the landscape.

Visual This route follows a core path uphill from Invergarry passed Loch Lundie and would result in cumulative impacts with existing overhead lines. Although these views are already reduced in sensitivity to this type of development the additional OHL could lead to a greater prominence in views.

Passing through Auchterawe, this route would potentially be very prominent from properties, the minor road and recreational routes. There would be a cumulative impact with the existing OHL.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with grassland (4.2) and sections of improved grassland (5.2) near Auchterawe.

Forestry Extension to existing wayleave required through Inchnacardoch Forest.

Recreation This route would lead to a cumulative impact on the core path round Loch Lundie (three routes) and may contribute to an impact on recreational enjoyment of these routes. It would also pass close to a Forestry Commission parking area and felling and an increased wayleave here could have some detraction from the recreational experience.

Planning


Policy Adherence to National, Regional and Local planning policy will in large part depend on avoiding or minimising potential constraints noted. The RAG rating therefore reflects the potential for impact on some of these features, as noted above, albeit opportunities do exist to minimise potential impacts.

Route 6B – Beauly – Denny Wayleave

Description:

From Glen Morriston, this route would follow the Beauly – Denny wayleave corridor to Fort Augustus Substation.


Natural Heritage


Designations No designated areas along this route, although adjacent to River Moriston SAC (designated for Atlantic salmon and freshwater pearl mussel). Potential indirect impacts on this designation would require consideration during construction but could be avoided.

Protected Species Northern end of this route is adjacent to the River Moriston SAC (see above).

There is potential for European Protected Species such as bats and otter to be present along the route, along with other protected species such as water vole, badger, pine marten, red squirrel and reptiles. Further survey work would be required to determine their presence along the route.

Habitats This route is predominantly through commercial forestry plantation, with areas of native woodland recorded at Glen Moriston. The northern end of this route crosses the Dundreggan Caledonian Pine buffer zone and includes areas of ancient woodland. The remnant pine wood and regeneration zone can be avoided by following the southern wayleave from 5C. All other semi-natural woodland areas along this route are avoidable.

Further survey work would be required to minimise potential impacts on areas of native woodland.

Ornithology Black grouse lek within the route buffer, therefore potential for collision, displacement and construction disturbance will need to be considered.

Hydrology / Geology


Properties likely to maintain private water supply sources. Catchment area to springs, wells and GWDTE likely to be similar to surface water catchment area.

Priority peatland mapping suggests that there is Class 1 and 2 (strong likelihood of deep peat and priority peatland habitats) located to the north of this route option. Peat probing to inform the final alignment may be required.

Pollution risks near to the River Moriston SAC will need to be considered.

Cultural Heritage


Designations One A-listed building, a bridge, at north end, with potential for setting impacts. Sensitive siting of alignment and towers would limit indirect (setting) impacts.

Properties within this route option are limited to a couple of properties close to Fort Augustus Substation. However, it may be difficult to avoid interactions with these properties, depending on final alignment and configuration into substation.



Designations The wider wayleave and new steel structures may be visible from the Loch Ness and Duntelchaig SLA. The appearance of the wayleave cutting up the glen-side could have a limited indirect impact on the Special Quality of ‘the dramatic Great Glen’ by diminishing the perceived height and steepness of the glen side but, given the existing wayleave and other OHLs in this location this is not considered to be notable.

Character This route passes from Wooded Glen LCT to Broad Steep-Sided Glen LCT through Rugged Massif LCT. Both the Wooded Glen LCT and Broad Steep-Sided Glen LCT are considered to have some ability to accommodate this type of development if well aligned. Whilst the Rugged Massif LCT is considered of higher sensitivity, as this route remains through forest planation within the LCT this is considered to be locally less sensitive.

The route would join the existing broad wayleave through coniferous forest which cuts up and over both glen sides. It is likely that this wayleave would need widened which may increase its prominence as a feature within the landscape, drawing attention to the numerous OHLs in this area and the Fort Augustus substation. The addition of another OHL to the already developed baseline has potential to lead to increase wirescape and cumulative impacts, particularly at either end as it enters the two glens.

Visual This route would be visible from parts of Fort Augustus and the A82 as a wider, more prominent wayleave. Steel structures would also likely to be visible with prominence depending on the structure option chosen. There would be potential cumulative impacts at either end of the route entering Auchterawe and Glen Moriston due to the large number of lines following this route. There is also the potential for increased visual impacts and cumulative visual impacts to views from recreational routes within forest due to the many different OHL types and additional tree loss.

Land Use


Agriculture Predominantly rough grazing through existing wayleave, dominated by plant communities of low grazing value.

Forestry Further removal of forestry required to widen Beauly – Denny wayleave.

Recreation This would contribute to a cumulative impact on some core paths and walking routes. Collectively this has the potential to reduce recreational enjoyment to a degree.

Route 6C – Skye T

Description:

This route option forms an alternative to Route 6A from the western extent of Inchnacardoch Forest to Fort Augustus Substation. This option would follow the route of the proposed Fort Augustus – Skye T OHL, thus avoiding the Auchterawe area.


Natural Heritage


Designations There are no designated sites within this route option. However, this option would require the southern extent of Route 6A which passes to the east of the West Inverness-shire Lochs SPA and SSSI (see Route 6A). The RAG rating takes account of this.

Protected Species Potential for European Protected Species to be present along the route could include bats and otter, and other protected species such as water vole, red squirrel, pine marten and reptiles.

Habitats No designated habitats along the route, which is predominantly commercial forestry. Ancient woodland is present along the route.

Ornithology This route would still require the southern extent of Route 6A which passes to the east of the West Inverness-shire Lochs SPA and SSSI (see Route 6A).

Hydrology / Geology

Character This route would directly affect Rocky Moorland LCT and the Broad Steep-Sided Glen LCT, both considered to have some degree of ability to accommodate a development of this type. It would also potential indirectly affect the Rugged Massif LCT which is considered to have higher sensitivity.

Following the same route as 6a through the Rocky Moorland LCT, the route would follow an existing steel lattice tower line. Whilst this reduces the sensitivity of the landscape, it would lead to potential for cumulative impacts and would increase the influence of overhead line development.

The remaining part of the route through the Broad Steep-Sided Glen LCT is mostly through forest which is usually broadly accommodating of this type of development. However, it is likely that the steel structures would be somewhat prominent in places due to their elevated position high on the hill. It is anticipated that this would replace the woodpole OHL which is currently along this route. Whilst this may slightly offset the impact, the steel structures would be taller and more prominent in the landscape, and likely to require a broader wayleave. It may therefore be more evident across a wider landscape area.

Visual This route follows the same alignment as Route 6a through its initial 3.5 km, following a core path uphill from Invergarry past Loch Lundie, and would result in cumulative impacts with existing overhead lines. Although these views are already reduced in sensitivity to this type of development the additional OHL could lead to a greater prominence in views and visual confusion if a non-steel lattice type structure were used.

The route would also be likely to be visible from parts of the A82 and Fort Augustus, including the steel structures which would be taller than the woodpoles which currently occupy this route, and as a widened wayleave through the forest. There would also be a potential cumulative impact from recreational routes through the forest with other routes following the Beauly – Denny wayleave closer to the substation.

Land Use



Forestry Likely increase in width of wayleave created for Skye T project required.

Recreation This route passes some recreational routes at either end but generally would have limited impact on recreational resources.

Route 6D – Caledonian Canal

Description:

This route option forms an alternative to Route 6A from the western extent of Inchnacardoch Forest to Fort Augustus Substation. This route crosses the Caledonian Canal to avoid the Auchterawe area, and would follow the Beauly – Denny wayleave corridor into the southeast of Fort Augustus Substation.


Natural Heritage


Designations There are no designated sites within this route, although this route option would require the southern extent of Route 6A which passes to the east of the West Inverness-shire Lochs SPA and SSSI (see Route 6A).

Protected Species Potential for European Protected Species could include bats and otter, along with other protected species such as water vole, red squirrel, pine marten and reptiles. Further survey work would be required to determine the presence of these species along the route.

Habitats No designated habitats along the route, which is predominantly heather moorland, peatlands, areas of native woodland and commercial forestry. This route would require felling within semi-natural woodlands for crossings of the Caledonian Canal.

Further survey work would be required to minimise impacts on these habitats. Ancient woodland is present in the north of the route.

Ornithology Desk study information has identified no particular ornithological sensitivities in its own right, but this route would still require the southern extent of Route 6A which passes to the east of the West Inverness-shire Lochs SPA and SSSI (see Route 6A).

Hydrology / Geology

This route crosses over a surface water drinking protection zone near Fort Augustus, and may compromise its quality and / or quantity.


Properties likely to maintain private water supply sources. Catchment area to springs, wells and GWDTE likely to be similar to surface water catchment area.One small area of Class 2 (strong likelihood of deep peat and priority peatland habitats) located to south of Kytra Lock. Peat depth probing may be required.

Crossing of Caledonian Canal.

Cultural Heritage


Designations Route option intersects with, and crosses, Caledonian Canal Scheduled Monument. Potential impacts on setting would need to be given due consideration during the alignment stage, as canal is important tourist route.

Route also passes close to Torr Dhuinn Fort Scheduled Monument. Potential indirect (setting) impacts on Torr Dhuinn Fort Scheduled Monument would require some consideration during the alignment stage.


Invervigar Isolation Hospital, Invervigar township and Coiltry township lie within route option. Consideration would need to be given to avoid and minimise potential impacts to recorded heritage assets, as well as the potential for encountering unrecorded archaeological remains. Given the nature of development it is considered that such opportunities to minimise impacts would exist.

People



Properties around Kytra locks and Auchterawe fall within this route although would be likely to be largely avoidable depending on alignment.

Landscape


Designations There may be some intervisibility of this route with the Loch Ness and Duntelchaig SLA and Loch Lochy and Loch Oich SLA with the potential for steel structures to appear within framed views within the Great Glen. However, this is unlikely to result in any notable impact on either of these SLAs.

Character This route would directly affect Rocky Moorland LCT and the Broad Steep-Sided Glen LCT, both considered to have some degree of ability to accommodate a development of this type.

Following the same route as Route 6A through the Rocky Moorland LCT, there would be potential cumulative impacts to the locally sensitive small scale landscapes around Loch Lundie due to the presence of existing OHLs.

Through the Broad Steep-sided Strath and within the Great Glen, the route through forest fringes and fields has the potential to be broadly accommodating but the height of steel structures would be likely to result in their being prominent within the valley floor. Although other steel lattice towers existing within part of this landscape this would affect a larger area and form a cumulative impact.

This route avoids some of the cumulative impacts of Routes 6A to 6C but would introduce major OHL development to a new area.

Visual This route follows the same alignment as 6a through its initial 3.5 km, following a core path uphill from Invergarry past Loch Lundie, This route follows a core path uphill from Invergarry passed Loch Lundie and would result in cumulative impacts with existing overhead lines. Although these views are already reduced in sensitivity to this type of development the additional OHL could lead to a greater prominence in views and visual confusion if a non-steel lattice type structure were used.

There would be potential views of this route from properties at and around Kytra Locks. There would also be views for recreational users of the Caledonian Canal and towpath and Great Glen Way long distance walking route. This route would be required to cross these recreational routes twice and there would potential for steel towers to appear prominent in these views.

There would also be potentially prominent views for recreational users using routes up Invervigar Burn.

Land Use


Agriculture Predominantly rough grazing, dominated by plant communities of low grazing value. Minor interaction with grassland (4.2) and sections of improved grassland (5.2) near Auchterawe and the River Oich.

Forestry Some felling and / or increase in wayleave corridor required.

Recreation This route would be required to cross the Caledonian Canal and Great Glen Way on two occasions which has the potential to result in adverse impacts. The method of crossing would be key in considering the potential level of impact.
