Landscape Appraisal: Winchester Barton Farm Area 1
(follow on from LDF Core Strategy Issues and Options Paper consultation response
February 2008)
Linda Thomas, Senior Landscape Architect, Landscape team, Environment
12 January 2008
Landscape Character Area: Wonston Downs
Ref: Landscape Character Assessment for Winchester District (March 2004)
Landscape Type: Open Arable (exposed)
Key Characteristics specific to this site:
Gently sloping and undulating topography (50-110OD)
Visually open and expansive landscape with long panoramic views over
the downs and key views to Winchester
Mainly arable with sparse tree/woodland cover consisting of shelterbelts,
mainly beech or coniferous.
Long straight hedgerows enclose a pattern of large fields
Landscape Strategies that apply to this site:
Conserve the large and generally regular field pattern and wide panoramic
views
Conserve structure and condition of existing hedgerows and isolated
woodlands and trees which contribute to biodiversity and character of
landscape
Manage semi-natural roadside verges to maximise biodiversity
Conserve the historic rural character of lanes, footpaths and drove roads
throughout the area
Physical Landscape:
Ref: GIS constraint map
Landform:
Ridgelines
Two E-W main ridgelines are predominant features of the site
1. the first lies between Harestock and Headbourne Worthy; c65-70m OD, and
follows public right of way within site (north of Barton Farm)
2. the second more significant ridgeline lies between Well House Lane and Down
Farm Lane along the northern boundary, c65-90m OD.
Dry valleys
Two main E-W dry valleys are predominant features of the site
1. route immediately to north of and parallel to Well House Lane, c50-60m OD.
Sewage Treatment Works located within this valley setting.
2. southern end of the site which crosses railway line and comprises existing gap
between settlement boundaries of Abbots Barton and Headbourne Worthy, c50-
60m OD.

  • Visually open and expansive landscape with long panoramic views over the downs and key views to Winchester
  • Mainly arable with sparse tree/woodland cover consisting of shelterbelts, mainly beech or coniferous.

Physical Landscape: Ref: GIS constraint map

Landform:

  • Ridgelines Two E-W main ridgelines are predominant features of the site
  1. the first lies between Harestock and Headbourne Worthy; c65-70m OD, and follows public right of way within site (north of Barton Farm)
  2. the second more significant ridgeline lies between Well House Lane and Down Farm Lane along the northern boundary, c65-90m OD.
  • Dry valleys Two main E-W dry valleys are predominant features of the site
  1. route immediately to north of and parallel to Well House Lane, c50-60m OD. Sewage Treatment Works located within this valley setting.
  2. southern end of the site which crosses railway line and comprises existing gap between settlement boundaries of Abbots Barton and Headbourne Worthy, c50- 60m OD.
  • Highest Point

Northern boundary of site, 80-90.0m OD.

  • Steep gradients
  1. Steep sloping profile down to road south of Well House Lane, including junction with Andover Road.
  2. Steep slopes east of railway line within dry valley setting
  • Significant changes of level on site boundaries
  1. Adjacent Andover Road North (between Well House Lane and S boundary)
  2. B3047 between Abbots Barton and Headbourne Worthy

Land cover:

  • Mainly large arable fields on sloping ground in an open landscape setting.
  • Small area of enclosed paddocks / areas of pasture south of Well House Lane.
  • Existing vegetation within site boundaries is generally weak or non- existent
  • Existing trees and hedgerows of amenity value outside site boundaries eg avenue in Andover Road.
  • TPO trees in SE corner by Abbots Barton

Significant areas of vegetation within or close to the site area include:

1.Shelterbelt skyline feature of mainly beech with shrub understorey along ridge following public right of way. Unploughed margin either side of shelterbelt, approx 10.0m width provides a robust green corridor of significant visual and biodiversity value.

  1. Railway embankment to east of site 3 Conifer belt north of sewage works and intermittent small copses to north of Well House Lane.
  2. Roadside vegetation either side of Well House Lane
  3. Trees and hedgerows adjoining Francis Gardens (includes TPO)
  4. Long sections of N-S and E-W trees and hedgerows throughout the site identifying field boundaries and tracks.

NOTE: Existing shelter belts and hedges are significant features in an open exposed landscape and take many years to establish before providing amenity / biodiversity benefits. Because of this, they should be considered a valuable asset and retained and enhanced wherever possible.

Experiential: Ref: GIS constraint map Ref: Tranquillity map (CPRE website)

  • Tranquillity Proposed South Downs National Park, which includes Itchen Valley, to east of site Open downland setting; peaceful. Tranquil semi-rural valley setting between Abbots Barton and Headbourne Worthy defines different settlement character areas.
  • Countryside Access
  • Skyline features and land marks Police HQ on Winchester skyline to S Teg Down telecom masts to SW Cheesefoot Head to SE (proposed SDNP) Tree belt on ridgeline within site

Landscape Sensitivity Summary

Any new development to recognise constraints of site including topography and slopes; main ridgelines with associated far-reaching visibility and skyline features; value of existing interconnecting footpaths and tracks, including their setting, throughout the site; importance of existing green corridors within and bordering the site in landscape and ecology terms; limitations of vehicular access into site; sensitive eastern boundary to River Itchen in terms of biodiversity, landscape character and heritage; integrity of Kings Worthy and Headbourne Worthy within its landscape setting as separate settlements to Winchester; importance of existing ridgelines as integral to character of Winchester city and its valley setting.
