                         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
Public Document Pack - Individual Executive Decisions ...
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.

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.

7. 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
Public Document Pack - Individual Executive Decisions ...
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.

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).

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. See figure 10

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

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
