Context
Introduction
7.14.1 The Avon Valley character area is
approximately 12sq km in area. It comprises the meandering River
Avon, its valley floor and the lower valley slopes especially where
they are significantly influenced by the presence of the railway
and major road which are so prominent in the valley. It extends
from the western edge of Bath to the area boundary north of
Keynsham where the Cadbury factory complex at Somerdale separates
off a smaller area to the west. The area is bounded by the Cotswold
Plateaux and Valleys character area to the east and the Hinton
Blewett and Newton St Loe Plateau Lands to the south as well as
shorter sections of other areas west of Keynsham.
Geology, Soils and Drainage
7.14.2 Drift deposits are an important
component of the surface geology throughout the area with alluvium
typically found through the floodplain as well as smaller outcrops
of river gravel and head. There are also a variety of solid
formations including Pennant Sandstone in the area of Corston, Lias
Limestone from Saltford to Kelston Park with visible outcrops for
example at Mead Lane, Saltford and Lias Clay from Keynsham to
Kelston to the north of the limestone.
7.14.3 Soils are generally clayey in nature
ranging from being well-drained in the limestone areas to being
slowly permeable or at risk of flooding such as beside the Avon.
There are also some well-drained fine loamy soils found over the
river gravels, for example to the east of Keynsham.
Principal Planning Designations
7.14.4 The northern part falls within the
Cotswold AONB with the boundary following the River Avon. The
southern part following a line along the River Avon, around the
edge of Corston, along the A4 and along the western edge of
Keynsham falls within the Forest of Avon community forest. The
whole of the rural area is also within the Bristol/Bath Green
Belt.
Description
Landform and Drainage Pattern
7.14.5 The landscape consists primarily of the
meandering River Avon and its wide valley with a generally flat or
gently sloping valley floor. Here the land is low-lying rarely
exceeding 50m in height. The valley sides where they are included
range from moderately steeply sloping around Corston, Newton St Loe
and Kelston to gently sloping as for example between Keynsham and
Saltford. The lower slopes are often undulating. The main line
railway has had a significant effect on the topography. Where it
runs across the flood plain it has been raised up in places on
steeply sloping embankments with other sections at grade or in
cutting. It has the effect of isolating parts of the flood plain
landscape from the River Avon.
Land-uses
7.14.6 Land-use within the area is varied,
often giving a patchwork of arable and grassland. Arable fields are
found particularly north of Saltford and around Corston to the edge
of Bath. There is also some horticultural use north east of
Keynsham. The reasonably level land close to urban areas favours
the use of the land for sports pitches such as near to the edge of
Keynsham and Corston. There is also ‘horsiculture’ in places
particularly to the north of Saltford and significant areas are in
light industrial or business use, including a substantial sewage
works at Saltford Mead.
Fields, Boundaries and Trees
7.14.7 The field boundaries are particularly
varied. Fences are used extensively. Hedges are also characteristic
and varied across the area with both clipped and unclipped hedges,
some with and some without trees. Walls tend to be localised and
mostly associated with farm buildings. In areas of intensive horse
grazing visually discordant white tape is used to divide
fields.
7.14.8 Fields are generally medium in size,
with some small and occasionally large fields, and are typically
angular in shape. Historically much of the area was enclosed during
the later Middle Ages from the earlier open fields. Of particular
note are the areas of rich, wet grassland beside the River Avon
such as at Keynsham Hams and north of Newton St Loe, which were
enclosed in the medieval period as areas of meadowland, providing
early seasonal growth of grass.
7.14.9 Much of the area has few trees but the
landscape is punctuated by a number of scattered small woods.
Tennant’s Wood and Kelston Park Wood are of particular note. They
are both registered as ancient semi-natural woodland. There
are trees lining the River Avon and also beside the Bristol and
Bath Railway Path and beside the main line railway. During the
1990’s there was considerable woodland planting under the aegis of
the Community Forest to the east of Keynsham. Development of this
community resource is ongoing.
Settlements and Communications
7.14.10 The Avon Valley is an important
transport corridor. The river was at one time an important means of
transport and is now primarily used for recreational purposes. The
A4 Bristol to Bath road passes through the corridor with
connections to each side of the valley. The Bristol to London
mainline railway also runs through the valley.
7.14.11 The area is bounded by Keynsham and
Bath. Keynsham is widely visible from within the area, whereas Bath
tends to be less prominent because of the topography of the city.
Saltford is the main settlement within the area. It is located on
the south-western slopes of the Avon Valley and is visible across
much of the character area. The historical centre of the village is
around the church on the north-east side. There has been subsequent
19th century development towards the river and the bulk of the
village is 20th century. Corston is the only other village and is
also located on the south-western slopes of the valley. The
southern part around the church is the historical centre. The
village expanded to the north in the 19th century and has two small
areas of 20th century development on the northern side. Other
settlement includes a group of houses at Durley Park and ribbon
development between Saltford and Keynsham. There are also isolated
farms and properties above the floodplain. Traditional building
materials include Oolitic and Lias Limestone often with red clay
tiled roofs. More recently brick and rendered houses with brown
concrete roofs have been built on the edges of Keynsham and at
Saltford.
Landscape Characteristics
7.14.12 The landscape has a generally open
character with views across the wide valley floor to the valley
sides and the hills and plateaux beyond. Kelston Round Hill and
Lansdown for example can appear very dramatic under certain
conditions such as when under low cloud. Occasionally longer views
are restricted by adjoining settlements, tall hedges, trees or the
railway on embankment.
7.14.13 The flat open nature of the landscape
gives prominence to features that otherwise might be lost in a more
enclosed landscape. Goal posts and buildings associated with the
sports fields are often major components of the view. Likewise
large mature trees and groups of trees, often including willow and
poplar, are also important elements of many views. The course of
the river edged by trees is a particularly important feature
throughout the area. Seasonal flooding can have a pronounced effect
on the character across the flood plain.
7.14.14 Development at the edges of the
settlements is often a major component of views especially around
and between Keynsham and Saltford. The Cadbury factory at Keynsham
with its prominent red brick construction is an important landmark
from many views. Likewise the Kelston Round Hill on the Cotswold
ridge to the north east with its group of trees is another
important landmark.
7.14.15 The noise from both road traffic and
trains is apparent across much of the area reinforcing the
importance of the valley as a transport corridor.
Landscape Change and Condition
7.14.16 There have been agricultural changes
locally leading to amalgamation of fields as well as a reduction in
the number of hedgerow trees. Most recent changes have come about
as a result of urban fringe pressures. This is indicated by the
presence of utility works, sports pitches and locally the use of
fields as horse paddocks.
7.14.17 Phytophthora disease has resulted in
dead and dying alders beside the river and is having a significant
impact on many views along this river valley landscape.
