Background 1.3 The proposals are for the demolition of an existing dwelling and outbuilding, and the erection of 31 dwellings, access and associated works. Proximity to European sites 1.4 The Peak District Dales SAC comprises thirteen separate dales, supporting ten interest features regarded as rare or threatened in a European context. The greatest in extent are the ash woodlands and the calcareous grasslands. 1.5 The Peak Dales SAC is designated for containing a number of Annex I habitats including semi-natural dry grasslands and Tilio-Acerion forests, and Annex II species including white clawed crayfish Austropotamobius pallipes. A location map and citation for the designated site is presented in Appendix 1. Details are summarised as follows: Special Area for Conservation (SAC) SAC name: Peak Dales SAC code: UK0019859 Cartesian Areas ha: 2326.33 1.6 The closest part of the SAC to the proposed development site above is a component Site of Special Scientific Interest (SSSI) known as The Wye Valley SSSI. This component site is located 4.5km east from the Macclesfield Old Road site at its closest point. The development site is separated from the SSSI/SAC by the Grin Low and Buxton Country Park and the town of Buxton. Legislative considerations 1.7 The Conservation of Habitats and Species Regulations 2010 (hereafter referred to in this report as the Habitats Regulations) make provision for implementing the EC 1 Directive on the Conservation of Natural Habitats and Wild Fauna and Flora in Great Britain (hereafter referred to as the Habitats Directive). The Habitat Regulations detail measures relating to the conservation of Special Areas of Conservation (SACs) and Special Protection Areas (SPAs)2. 1.8 The Habitats Directive requires that the interest features (the species and habitats that occur on a European site) should be maintained in favourable conservation 1 Directive92/43/EEC, amended by Directive 97/62/EC 2 Classified under the Wild Birds Directive 79/409/EEC Doc Ref: 4984.001 February 2015 Version: 1.0 19 Macclesfield Old Road Buxton Assessment of Likely Significant Effects status. The Habitats Directive defines the conservation status of a species as favourable when: — population dynamics data on the species concerned indicate that it is maintaining itself on a long-term basis as a viable component of its natural habitats, and — the natural range of the species is neither being reduced nor is likely to be reduced for the foreseeable future, and — there is, and will probably continue to be, a sufficiently large habitat to maintain its populations on a long-term basis; 1.9 The Habitats Directive defines the conservation status of a habitat as favourable when: — its natural range and areas it covers within that range are stable or increasing, and — the specific structure and functions which are necessary for its long-term maintenance exist and are likely to continue to exist for the foreseeable future, and — the conservation status of its typical species is favourable 1.10 To ensure European sites are managed to achieve and maintain favourable conservation status, objectives specific to the interest features are identified for each site. These include objectives relating to the maintenance of existing habitats, the monitoring of species distribution and abundance, and the assessment of potentially damaging activities. 1.11 Competent authorities have a statutory duty under Regulation 61 of the Habitats Regulations, to assess the implications of a plan or project on a European site: 61.—(1) A competent authority, before deciding to undertake, or give any consent, permission or other authorisation for, a plan or project which— (a) is likely to have a significant effect on a European site or a European offshore marine site (either alone or in combination with other plans or projects), and (b) is not directly connected with or necessary to the management of that site,. must make an appropriate assessment of the implications for that site in view of that site’s conservation objectives Approach 1.12 The first stage of exercising the duty imposed by Regulation 61 of the Habitats Regulation is therefore to assess whether the proposed housing development at Macclesfield Old Road, Buxton is likely to have a significant effect on the Peak Dales SAC, either alone or in combination with other plans or projects. It is also necessary to determine if the proposals are directly connected with or necessary to the management of the site. 1.13 There are no known plans or projects which may have in combination effects relevant to the proposals, however this is addressed later in the assessment. 1.14 To establish the baseline conditions of the site for the ALSE, ecological surveys have been carried out. The survey area includes the site and immediately adjacent land. Doc Ref: 4984.001 February 2015 Version: 1.0 20 Macclesfield Old Road Buxton Assessment of Likely Significant Effects 1.15 An extended Phase 1 Habitat survey was undertaken to identify key habitats and botanical species of interest within and adjacent to the proposed development site. 1.16 An appraisal of bird species likely to be using the habitats within the proposed development site was also completed. 2.0 DEVELOPMENT PROPOSALS Description of the site 2.1 The location of the site and surrounding area is illustrated at Drawing G4984.001. The site comprises 1.28ha of land which lies immediately adjacent to the south of Macclesfield Old Road at the south western end of Buxton. 2.2 The application site consists of two distinct halves separated by a dry stone wall and fence. The eastern half of the site contains an occupied dwelling which is surrounded by a large unmanaged garden and detached outbuildings. The western half of the application site contains grazed semi-improved neutral grassland bounded by a dry stone wall. 2.3 To the north and north-west of the site the land slopes upwards towards the Peak District National Park. Immediately north of Macclesfield Old Road to the north of the site are a few large grazed improved grassland fields. To the west of this is a strip of woodland plantation known as Burbage-edge plantation. North and west of this is a large area of moorland. 2.4 The town of Buxton borders the east of the site, the closest part known as Burbage. To the south east of the site is an area of new housing. Directly south of the site is an area of marshy grassland on the site of an in-filled reservoir. Description of works 2.5 The proposed scheme is to build 31 new detached properties. Vehicular access onto the site will be provided via the existing access point on Macclesfield Old Road. 2.6 Car parking provision on the site will be in accordance with Derbyshire County Council’s ‘Car Parking Standards in Derbyshire – Guidance Notes’. Within the site an access road which follows the existing access road will be provided. This will comprise two short (<25m) sections of 3.5m width with a 5.5m passing area. 2.7 The peak increase in traffic generated by the site has been calculated in the Transport Note produced by SBA. It was calculated that the trip generation from the proposed development will result in 19 two-way trips in the morning peak (08:00 – 09:00) and 20 two-way trips in the afternoon peak (17:00 – 18:00). The report concludes that the traffic generated by the proposed development will be minimal. Doc Ref: 4984.001 February 2015 Version: 1.0 21 Macclesfield Old Road Buxton Assessment of Likely Significant Effects 3.0 FEATURES OF INTEREST IN THE RELEVANT EUROPEAN SITE The Peak Dales SAC 3.1 The Peak Dales SAC is of international importance due to the Annex I habitats and Annex II species it supports. 3.2 The majority of the site comprises semi-natural dry grasslands and Tilio-Acerion forests. 3.3 The land use within this area is driven by a combination of agriculture, rough grazing for sheep and grouse shooting. Ecosystem maintenance relies on appropriate management of grazing and burning regimes. Overgrazing by sheep, scrub invasion and inappropriate drainage all present threats to the ecosystem. 3.4 Favourable management is attempting to be achieved through a number of projects, including the Countryside Stewardship Scheme and the White Peak Wildlife Enhancement Scheme.

  • Peak District Mines Historical Society Ltd
    Peak District Mines Historical Society Ltd. Newsletter No. 142 April 2012 The Observations and Discoveries; Their Tenth Birthday! In this Newsletter we depart from what has become tradition and do not have a normal issue of Peak District Mines Observations and Discoveries, but instead have an index of the first forty sets of notes; ten years on since the first, this seems a perfect time to do this. The onerous task of compiling this index has fallen to Adam Russell, who very kindly volunteered to do this without prompting from us. We are very grateful. When we started I don’t think we ever envisaged there would be so many notes and with failing memory there is an increasing need to have an index to help easily find the various jottings when we need to refer back to something. We also take this opportunity to thank the many people who have contributed notes over the years – these have enlivened the Observations and Discoveries no end. This said, we always need more – if you have found something new or interesting, explored a shaft people don’t often go down or entered a mine where there is no readily available description of what is there, please consider writing a short note. There are literally hundreds of mines in the Peak where we have no idea what lies below ground – most were presumably explored in the 60s or 70s but often nothing was written down, and a new generation is now having to reinvent the wheel. We were gratified to learn, from the Reader Survey on the content of the newsletter that Steve undertook last year, just how much you, the readers, appreciated these notes.

  • Local Environment Agency Pi
    local environment agency pi DOVE ENVIRONMENTAL OVERVIEW AUGUST 1999 Ashbourne Dove LEAP Foreword I am delighted to introduce the Consultation Draft for the Dove Local Environment Agency Plan. This is the third LEAP to be produced in the Upper Trent Area of the Midlands Region and looks at environmental issues within the River Dove catchment. The Agency in consultation with key organisations has identified a number of environmental issues relevant to this area. We need to confirm that we have addressed all current issues and the options to resolve them, taking into account the often conflicting demands on the environment by its users. The LEAP process will provide a vision for the environmental needs of the River Dove area. It will provide a framework within which we can seek to develop new partnerships with organisations and bodies with whom we wish to share a common approach on environmental , issues. This report is published as part of our commitment to being open and consulting with others about our work. This will be part of a major consultation exercise and marks the start of a three month period of consultation. Following the consultation period the Agency will produce a five year action plan which will set out a costed programme of work by the Agency and other organisations. Annual reviews over the five year period will report on significant achievements and progress being made on the issues. Your views are extremely important. Only by letting us know your opinions will we be able to make a real difference to your local environment.

So many parishes in S.E. Derbyshire have been dealt with in this Series that it was hoped and intended that the present volume would be devoted entirely to the High Peak district and would contain a compact group of adjacent parishes, an arrangement which always brings out in a peculiar degree the value of this method of printing the complete Marriage Registers of a whole district. Unfortunately it was not found possible to obtain sufficient MS. from the High Peak without delaying indefinitely the issue of the volume, already overdue. The latter third of the book, therefore, has been filled with the important Register of Repton, the MS. of which had been ready for some time. The Repton abstracts were made by Mr. Simpson and Mr. E.

  • JBA Consulting
    Land at Elnor Lane Farm, Whaley Bridge: LVA Note to file 1.1 JBA Comments on views from National Park JBA Consulting provided a Landscape and Visual (LV) supplementary information report to accompany an outline planning application for 82 dwellings on land to the southern edge of Whaley Bridge in Derbyshire. The report include a review of relevant policy/evidence base documents and a summary of likely landscape and visual effects, accompanied by viewpoints from key locations and a Zone of Theoretical Visibility (ZTV) drawing. The potential for adverse impacts on the Park were raised during the Local Plan housing allocation process. The supplementary LV report considered that views from the Park were limited, being largely restricted to high ground of Taxal Moor, around 1.5km to the southwest. It concluded that, where visible, it may locally be noticeable but represent “little or no intrusion outside the existing settlement edge and would be a minor element in expansive views”. Representations were subsequently received from the Park Authority during the application stage: The Authority is concerned that the proposal is a visible intrusion into the landscape and therefore harmful to the flow of landscape character beyond the National Park boundary. It would detract from the setting of the National Park . While the site is not very visible from the roads (Elnor Lane and the [A]5004) due to aspect, high hedges & trees, the developers own Zone of Theoretical Visibility drawing shows that it is visible from large expanses of the adjacent national park, especially of Taxal Moor. Further to these comments, a sketch visualisation was prepared by others to demonstrate potential views from Taxal Moor.

  • Review of Tufa Deposition and Palaeohydrological Conditions in the White Peak, Derbyshire, UK: Implications for Quaternary Landscape Evolution
    CORE Metadata, citation and similar papers at core.ac.uk Provided by NERC Open Research Archive Review of tufa deposition and palaeohydrological conditions in the White Peak, Derbyshire, UK: implications for Quaternary landscape evolution. Vanessa J. Banks1,2*, Peter F. Jones2, David J. Lowe1, Jonathan R. Lee1, Jeremy Rushton1, and Michael A. Ellis1. 1 British Geological Survey, Kingsley Dunham Centre, Nicker Hill, Keyworth, Nottingham NG12 5GG 2 University of Derby, Geographical, Earth and Environmental Sciences, Kedleston Road, Derby, DE22 1GB * Corresponding author. E‐mail address: [email protected] Abstract. This review considers the geological and geomorphological context of tufa barrages that occupy buried valley settings in the Wye catchment, Derbyshire. It describes the potential relationship of the tufa with locations of hypothesised river captures and inception horizon‐guided groundwater flow paths. Tufa barrage development is associated with steps in the bedrock, which may be related to knick‐point recession during river capture. Broad estimates of valley incision have been calculated from previously dated deposits. These support current interpretations of particularly significant effective base‐level lowering during the Anglian and Devensian stages of the Quaternary and have the potential to add to the knowledge of regional uplift histories. Key words: tufa, Quaternary hydrogeology, inception horizons, incision, landscape evolution. 1. Introduction. Tufa is a terrestrial freshwater accumulation of calcium carbonate (Viles, 2004) that is commonly found in limestone terrain. Also referred to as travertine by some authors (Pentecost, 1999), it is precipitated when water that is saturated with calcium carbonate becomes supersaturated due to degassing of carbon dioxide. This can be caused by: atmospheric absorption of carbon dioxide, increase in temperature, decrease in pressure, physical agitation, aquatic plant photosynthesis (Lorah and Herman, 1988), or microbial processes (Pedley and Rogerson, 2010).
