Public Document Pack High Peak Borough Council THE EXECUTIVE - INDIVIDUAL EXECUTIVE DECISIONS Date: Wednesday, 24 April 2019 23 April 2019 PART 1 1. Adoption of Site Specific Tree Management Guidance for The Slopes, Buxton (Pages 3 - 18) SIMON BAKER CHIEF EXECUTIVE
Agenda Item 1 HIGH PEAK BOROUGH COUNCIL Report to the Executive Councillor for Finance & Operational Services 23 April 2019 TITLE: Adoption of Site Specific Tree Management Guidance for The Slopes, Buxton . PORTFOLIO: Councillor Emily Thrane – Executive Councillor for Operational Services OFFICER: Monica Gillespie – Arboricultural Officer WARDS: Central Ward Appendices Attached – Appendix 1 - Site Specific Tree Management Guidance 1 – The Slopes, Buxton 1. Reason for the Report: 1.1 To seek approval to adopt a Site Specific Tree Management Guidance for The Slopes, Buxton to reflect the heritage of the site and allow for the original intention of the design to be re-established. 2. Recommendation 2.1 That the attached ‘Site Specific Tree Management Guidance 1 – The Slopes Buxton’ is adopted and appended to High Peak Borough Council’s Tree Strategy. 3. Executive Summary 3.1 The Slopes is a public open space and is Grade II Registered Historic Park and Garden located between the Town Hall and The Crescent in Buxton. The Slopes open space includes a war memorial and a weather station which was installed in 1867 making it the second oldest weather station in the UK. Page 3
3.2 The site is planted with around 100 trees. In 1818, the Slopes were laid out by Jeffry Wyatville with later additions by Joseph Paxton. The original layout had open views to the Crescent; trees were added through the 19th and 20th centuries. 3.3 In adopting this Site Specific Tree Management Guidance as provided at Appendix 1, for the Slopes, we are seeking to re-establish the views towards iconic Buxton Buildings such as the Crescent. It has been unofficial policy for some time to not undertake any replacement planting within the central area of the slopes so that as trees are removed, due to their condition or safety issues, the original views are re-established. The Guidance we are proposing for this specific site formalises this approach. 4. How this report links to Corporate Priorities 4.1 Developing a sustainable Site Specific Tree Management Guidance for the Slopes is in line with corporate policy to protect and improve the environment and provide quality parks and open space. 5. Options and Analysis 5.1 There are two options available: 1. To adopt the proposed Site Specific Tree Management Guidance ensuring the heritage of the site including views of many Buxton buildings is protected. (Recommended) 2. To not adopt the proposed Site Specific Tree Management Guidance replying on unofficial policy as has been the case for many years. (Not recommended) 6. Implications 6.1 Community Safety – (Crime and Disorder Act 1998) The proposed management approach will assist in maintaining open views across the site, which will encourage usage of the site and passive supervision, thus helping to create safe environments. 6.2 Workforce Any tree works required will be undertaken by the council’s approved contractors with tree planting and young tree management undertaken by AES, following the transfer of grounds maintenance services on the 1st April 2019. 6.3 Equality and Diversity/Equality Impact Assessment Ensuring the park is well managed and that there are good open views will help to maintain the accessibility of the park. 6.4 Financial Considerations The cost of the works and the replacement planting will be met out of existing tree works budgets. Page 4
6.5 Legal None 6.6 Sustainability The proposed management guidance will ensure a replacement tree is planted for every mature tree removed. 6.7 Internal and External Consultation Regeneration were consulted and commented on the plan. If approved, the plan will become public document and will be shared with local interest groups such as The Buxton Town Team and Buxton Civic Association. In addition Buxton ward councillors have been consulted with and raised no objections. 6.8 Risk Assessment HPBC have a duty to manage risk in relation to trees on land that it manages and owns. This approach is set out in Good Practice Guide No 4 – Tree Risk Management. The trees on the Slopes are managed in accordance with this guidance, if any of the trees become an unacceptable risk, they will be removed and replaced in accordance with the proposed management guidance for this site.

Background 7.1 The Slopes is a public open space and is Grade II Registered Historic Park and Garden located between the Town Hall and The Crescent in Buxton. The Slopes open space includes a war memorial and a weather station which was installed in 1867 making it the second oldest weather station in the UK. 7.2 The site is laid out with curved terraced paths which are linked by other paths which curve in the opposite direction, forming a pattern of interlocking ellipses. The pattern conforms broadly with that shown on the 1848 Tithe map and the original layout. The site is planted with around 100 trees. In 1818, the Slopes Page 5
were laid out by Jeffry Wyatville with later additions by Joseph Paxton. The original layout had open views to the Crescent but trees were added through the 19th and 20th centuries. 7.3 Over the years there have been various waves of tree planting on the Slopes which have gradually closed in the views towards the Crescent moving further from the original design. However the trees have become an important heritage element in their own right. 7.4 The proposal will allow for the retention and replacement of trees, recognising the important contribution they make to the environment whilst respecting the heritage elements of the Slopes including the original landscape intentions. 7.5 In 1991-94 proactive tree management removed around 50 dead and diseased trees thus reducing the density of trees on The Slopes. Since then trees have only been removed as required and replacement trees planted outside the main views. 7.6 The option to undertake a further phase of significant tree removal has been dismissed as this will lead to the loss of otherwise healthy trees and be contrary to the Councils current Tree Strategy. 7.7 In adopting this Site Specific Tree Management Guidance, provided at Appendix 1, for the Slopes, we are seeking to re-establish the views towards iconic Buxton Buildings such as the Crescent. It has been unofficial policy for some time to not undertake any replacement planting within the central area of the Slopes so that as trees are removed, due to their condition or as a result of safety concerns, the original views are re-established. The Guidance we are proposing for this site therefore aims to formalise this approach. Page 6
Site Specific Tree Management Guidance 1 – The Slopes Buxton 1. Background and History 1.1 The Slopes is a public open space and is Grade II Registered Historic Park and Garden. It is located between the Town Hall and The Crescent. The land rises steeply up from the forecourt of the Crescent to the south. The site is laid out with curved terraced paths which are linked by other paths which curve in the opposite direction, forming a pattern of interlocking ellipses. The pattern conforms broadly with that shown on the 1848 Tithe map and the original layout. The site has around 100 mature trees. The Slopes also has a war memorial and a weather station 1867 and is the second oldest weather station in the UK. 1.2 It is known that this area was originally a bare hillside called St Ann's Cliff. But there is evidence that even early in its evolution as a public space the upper slopes to the south were planted with trees particularly the south east. 1.3 The development of tree cover on the slopes is illustrated via Ordnance Survey (OS)- map extracts and images from 1850 onwards in Figures 1-9 appended to this report. 1.4 1818 - The Slopes were laid out by Jeffry Wyatville for the sixth Duke of Devonshire to form the setting for the Crescent and attached buildings relating to the spa. Wyatville’s design established the pattern of interlocking ellipse but was without trees and relied on stone retaining walls, flights of steps and huge stone urns as decoration and which all survive. The walls, steps and urns are all separately listed (Grade II*). The urns themselves are of particularly important provenance, being made of oolitic limestone (Bath Stone), were designed by the prominent advocate of Palladian architecture, Richard Boyle (Lord Burlington), for the Cavendish family’s East Riding of Yorkshire estate at Londesborough in 1746. they were brought to Buxton by Wyatville in 1818 following the sixth Duke’s decision to demolish Londesborough. 1.5 1835 - The Butterly Directory described the area as: 'Over St Ann's Cliffs; opposite the Crescent, a fine rising lawn has been laid out with very great taste, where the company promenade'. 1.6 1850’s - subsequent alterations were carried out by Joseph Paxton. The OS maps for this period show trees particularly to the east and west of the site. To be marked on the plan they must have been quite established suggesting that these may have been part of the earlier original layout of the site. 1.7 1890’s more trees were added to the slopes this can been seen in photos showing young trees and by reviewing the OS maps 1.8 In the C19 the seventh Duke of Devonshire sold the site on a chief rent to the Buxton Local Board (which subsequently became the Buxton Corporation). 2|Page Revision 1 : February 2019 Page 8
Site Specific Tree Management Guidance 1 – The Slopes Buxton 1.9 A photo from circa 1927 shows mature to the south east trees and some other younger trees. The Avenue and the upper part of the slopes to the south and east has the more mature trees. 1.10 A comprehensive Conservation and Landscape Management Plan of the Slopes was undertaken in 1991-4 when the Council successfully bid to the European Commission for funding matched with its own funds and those of English Heritage to create a project budget of approximately £400,000. At this time, all of the hard elements of the Slopes (paths, path edgings, retaining walls and urns) were repaired, some 50 dying or diseased trees were removed and a further 12 trees planted. Turners Memorial was reinstated and the area at the foot of the Slopes was landscaped as part of the same project. One of the tree management principles adopted with this project was to open up views of the Crescent from the War Memorial southwards. 1.10 A chronological sequence of maps and photos is appended to this document through which the above developments can be traced. 2. The trees 2.1 There are now up to 100 mature trees on site. There are indications that those to the south and east are more mature including some large elms trees. There is an even aged avenue of sycamores which appears to be consistent with the line of the older planting on site. The trees added circa 1900 area predominant to the north and central area of the site. There is also some more recent tree planting replacing trees that have been felled. 2.2 Most, although not all, the trees are have been included in the council’s survey Ezy Treev Management System. 2.3 The majority of trees are lime or sycamore with the occasional elm and ash. There were several horse chestnuts but these have all succumbed to disease in the last 10 years. 2.4 Over the last 10 years 10 trees have been removed: 5 horse chestnut and 5 sycamore. Each tree that has been removed has been replaced on at least a 1:1 basis with a standard tree usually of either a species of lime or maple. 2.5 The ‘unofficial’ replacement planting policy has been to replace trees to the east or west of the site to allow the natural development of a more open vista towards the Crescent and other iconic Buxton buildings, building on the principle introduced with the 1991-94 plan, and bringing the distribution of trees closer to the original layout.

Site Specific Tree Management Guidance 1 – The Slopes Buxton 3. Formalising future management 3.1 The renovation of the Crescent is now nearing completion and the views towards this iconic building are limited from the upper parts of the slopes. The trees on the Slopes are mature and where they are healthy and there is no other justification for the removal of the trees they should be retained. Decisions with regards to the retention of trees or otherwise will be made in line with the Council’s Tree Policy. It would not be appropriate to undertaken any type of wholesale felling with the sole reason of opening up the views. The trees are an asset and have their own heritage value as well as having an environmental importance; all of which needs to be recognised that needs to be recognised. 3.2 A review of the photos and OS maps suggest that the earlier alterations and extensions to the original layout may have included trees but retained and open vista in the central triangle of the site. Also when the trees were young the view was naturally more open see figures 6-8. 3.3 The development of Buxton as Spa town and the influence of various architects and landscapers on the town is an important part of the town’s heritage and character. Therefore it is important to recognised and be sympathetic to the original landscape vision but we do not have details of what longer term intentions of the instigators of the layout were. But it would seem logical, given the historical development of the site, that the intention was to have trees on the upper slopes to the south east and also to the south west but the central area would be more open. 3.4 There are other important heritage features on the Slopes including the weather recording site. This is the second longest running weather recording station in the UK and established in 1866 . The trees do have some impact on the site weather station and a recent report has identified several trees causing issues. The Slopes is also home to the town’s fine War Memorial by L.f Roslyn. 3.5 Both these features fall within the central triangle of the site and would also benefit from a policy of allowing this area to be gradually opened up when the current trees need to be removed 3.6 The trees themselves are heritage features most are at least 120 years old with several that are potentially as much as 200 years old. They also have a value as a capital asset and the provide ecological benefits 3.7 The attached plan Figure 9 shows the no planting zone. The policy being that if trees have to be removed for other reasons they will not be replaced in this area to allow the natural and progressive opening up of views. 3.8. Replacement tree planting will be undertaken outside this area on a 1:1 basis using species similar stature and characteristics to those already established 4|Page Revision 1 : February 2019 Page 10
Site Specific Tree Management Guidance 1 – The Slopes Buxton on the slopes; lime (Tilia spp) and maple or sycamore (Acer spp) predominate with some horse chestnut , elm and ash –due to disease these are less suitable for selection as replacement species at the current time. 4. Summary 4. Having given consideration to the various factors the tree felling and replacement policy for the slopes will be as follows Any tree felling will be considered in line with the Council Tree Policy and Good Practice Guidance. Any trees felled within the central triangle as illustrated in Figure 10 will not be replaced within that area unless there is any overriding reason to do so and its long term impact on the open vista and heritage features has been given due consideration. All future replacement planting will be predominantly to the south east and to a lesser extent to the south west of the site outside of this area. Species selection will in keeping with the historic planting on the which is largely lime, sycamore, horse chestnut, ash, elm and maple Report dated 4/2/2019 Following revisions as a result of various consultations 5|Page Revision 1 : February 2019 Page 11
