  • Proposed Erection of Wind Farm at Costa Head Swannay
    Item: 3.1 Planning Committee: 31 August 2018. Erect Four Wind Turbines, Meteorological Mast, Substation and Associated Infrastructure including Access Track at Costa Head (Land Near), Swannay. Report by Executive Director of Development and Infrastructure. 1. Summary 1.1. The proposal is for a commercial wind farm comprising 4 wind turbines, each with a maximum blade tip height of 125 metres, a combined maximum installed capacity of 16.32 megawatts and a 25 year operational phase near Costa Head, Swannay. The development also includes an electrical substation, an anemometer mast, an access route from the A966 to the substation and each of the turbines, culverted water course crossings, a crane pad and assembly area adjacent to each turbine foundation, underground cabling connecting the turbines to the substation, and a temporary construction compound. A total of 51 objections have been received and 15 letters of support. The report considers the development in relation to National Planning Framework 3 and Scottish Planning Policy, as well as the Orkney Local Development Plan 2017 and relevant Supplementary Guidance. Issues considered in the report include: shadow flicker; noise; traffic; tourism and recreation; peat and carbon rich soils; water environment; aviation, defence and communications; visual amenity; ecology and nature conservation; ornithology; historic environment; landscape and visual impact; employment; shared ownership; energy output and carbon considerations; and the subsea cable transmission link. Many issues are already considered to have no unacceptable impact, through design iteration, mitigation as could be controlled by planning conditions, or a combination. Consideration is finely balanced between the benefits and residual adverse effects.

  • Orkney and Shetland
    Orkney and Shetland: A Landscape Fashioned by Geology Orkney and Shetland Orkney and Shetland are the most northerly British remnants of a mountain range that once soared to Himalayan heights. These Caledonian mountains were formed when continents collided around A Landscape Fashioned by Geology 420 million years old. Alan McKirdy Whilst the bulk of the land comprising the Orkney Islands is relatively low-lying, there are spectacular coastlines to enjoy; the highlight of which is the magnificent 137m high Old Man of Hoy. Many of the coastal cliffs are carved in vivid red sandstones – the Old Red Sandstone. The material is also widely used as a building stone and has shaped the character of the islands’ many settlements. The 12th Century St. Magnus Cathedral is a particularly fine example of how this local stone has been used. OrKney A Shetland is built largely from the eroded stumps of the Caledonian Mountains. This ancient basement is pock-marked with granites and related rocks that were generated as the continents collided. The islands of the Shetland archipelago are also fringed by spectacular coastal features, nd such as rock arches, plunging cliffs and unspoilt beaches. The geology of Muckle Flugga and the ShetLAnd: A LA Holes of Scraada are amongst the delights geologists and tourists alike can enjoy. About the author Alan McKirdy has worked in conservation for over thirty years. He has played a variety of roles during that period; latterly as Head of Information Management at SNH. Alan has edited the Landscape nd Fashioned by Geology series since its inception and anticipates the completion of this 20 title series ScA shortly.

  • Scottish Sea-Stacks
    Scottish Sea-Stacks The ribald Scottish comedian Billy Connolly once commented that his country folk were so sun deprived they’d developed a blue tinge that required two weeks of sunshine just to return to a white hue before the real tanning could commence. I feel similarly tinted whilst standing on the last bit of the “Mainland” Orkney Isle, white, puffy clouds dappling overhead as sea spray further hazes the air and desire to continue. I stare across half a pool length of surging Atlantic at our primary objective, the daunting 250-foot sea stack of Yesnaby Castle. In my boxers and chilled to the core, I’m dreading the plunge, but someone has to get the 9mm rope across so we can safely haul our kit. Reasoning that the regional Gulf Stream-warmed water will keep away anything larger than me on the food chain, I spring from clenched feet, to stretch the dive and minimize swimming distance. Water temperature is pondered along with the power of the undertow in that hung second; I’m under, and then resurface, engaging a front crawl as rapid as the now-racing moment. I’m grateful for the swell that allows a clutch on the tower’s edge and quick mantle before dropping seas can take me down. I make a couple of moves to safety, zip-line gear across the boiling gap, and establish a Tyrolean for my friends, still dry and trying not to chuckle at my shivering form. Our goal for the day is the east-facing landward arête, an atmospheric double- overhanging edge - E2 5b (5.10) -- with good but intricate gear.

  • Evie to Birsay Route Description
    Evie to Birsay Route description Begin at the Broch of Gurness, where there is ample car parking and, if you wish, the opportunity to visit the Iron Age fort, which is Scotland’s best preserved broch village. Walk south along the road to the Sands of Evie. At low tide you can cross the burn and walk along the beach, but at high tide you’ll need to continue a little further along the road to where it turns sharply left. Take the track to the right and this will lead you above the beach to the car park and public toilets at the west end of the Sands. From here the track continues along the coast, past the Knowe of Stenso and onto the remains of the Knowe of Grugar. At this point the coast becomes too treacherous to navigate, especially at high tide, and so a fenced track leads up to the road at Grugar. Walking along the road affords a different view of the uninhabited island of Eynhallow with its ruined twelfth century church. Continue along the road until just after the Burn of Millhouse. Here a fenced track at Outer Urrigar leads you back to the coast and past the ruined St Peter’s Kirk. It is possible to walk all the way along the coast to Costa Hill but in the summer there are unfenced fields of cattle and so the Way leaves the coast again at Lower Arsdale, continuing along the road past Crismo to Costa Hill. A track leads up the hill to the summit, from where there are waymarkers along the north west bearing to the cliffs, joining the coastal route from around the back of Costa Head.
