Chew Valley in Somerset

The villages in the valley have their own parish councils which have responsibility for local issues. They also elect councillors to district councils e. g. Mendip and Somerset County Council or unitary authorities e. g. Bath and North East Somerset or North Somerset, which have wider responsibilities for services such as education, refuse and tourism. Each of the villages is also part of a constituency, either North East Somerset or North Somerset. Avon and Somerset Constabulary provides police services to the area.

The western end of the area (around Nempnett Thrubwell) consists of the Harptree Beds which incorporate silicified clay, shale and Lias Limestone. Clifton Down Limestone, which includes calcite and dolomitic mudstones of the Carboniferous period, is found in the adjoining central band and dolomitic conglomerate of the Triassic period. There are two main soil types, both generally well drained. The transition between the gently sloping landscape of the Upper Chew and Yeo Valleys and the open landscape of the Mendip Hills plateau is a scarp slope of 75 to 235 metres (250–770 ft). The predominant formation is Dolomitic Conglomerate of the Triassic period. It formed as a result of desert erosion and weathering of the scarp slopes. It takes the form of rock fragments mainly derived from older Carboniferous Limestone cemented together by lime and sand which hardened to give the appearance of concrete. Hartcliff Rocks Quarry and Dundry Main Road South Quarry. The oldest geological formation in the valley is the Supra Pennant Measures of the Carboniferous period. It is a significant feature towards the north eastern part of the area and is represented by the Pensford Syncline coal basin, which formed part of the Somerset coalfield. It is a complex formation containing coal seams and is made up of clay and shales. The landscape is typically undulating and includes outcrops of sandstone. Most of the area around Stanton Drew have neutral to acid red loamy soils with slowly permeable subsoils. Soils to the eastern part of the area are slowly permeable clayey and fine silty soils. They are found on Carboniferous clay and shales typical of the Supra Pennant Measures. They are frequently waterlogged where the topography dictates. They tend towards being acid and are brown to grey brown in colour. Burledge Hill, Chew Valley Lake, Compton Martin Ochre Mine, Harptree Combe and two sites at Folly Farm.

The small and medium sized fields of the valley are generally bounded by hedges and occasionally by tree belts and woodland, some of which date back to the most evident period of enclosure of earlier open fields which took place in the late medieval period. Hedgerows support the nationally rare Bithynian vetch (Vicia bithynica). Mature oak (Quercus) and ash (Fraxinus excelsior) trees are characteristic of the area with occasional groups of scots pine (Pinus sylvestris) and chestnuts (Castanea sativa). Elm (Ulmus) trees have been lost in this area, and dead/dying elms are also evident in the surrounding landscape. a wide variety of other bird species can be seen. These range from small birds such as great tits and wrens to mistle thrush. Larger birds include great spotted woodpeckers and common buzzard. The valley also has a wide variety of small mammals with larger species including Eurasian badger and deer. The valley is home to fifteen of the sixteen bats found in England including a roost, at Compton Martin Ochre Mine, for greater horseshoe bats. A rare and endangered species, the greater horseshoe bat is protected under the Wildlife and Countryside Act 1981 and is listed in Annex II of the 1992 European Community Habitats Directive.

Archaeological excavations carried out before the flooding of Chew Valley Lake found evidence of people belonging to the consecutive periods known as Upper Palaeolithic, Mesolithic and Neolithic (Old, Middle and New Stone Age), Bronze Age and Iron Age, comprising implements such as stone knives, flint blades and the head of a mace, along with buildings and graves. Other evidence of occupation from prehistoric times is provided by the henge monument at Stanton Drew, long barrow at Chewton Mendip, and Fairy Toot tumulus at Nempnett Thrubwell. Maes Knoll fort, on Dundry Down in the northern reaches of the valley, is a Scheduled Ancient Monument that dates from the Iron Age; it later served as a terminus for the early medieval Wansdyke earthworks. There is evidence of Roman remains in particular a villa and burial pits. Artefacts from the valley were sent to the British Museum. Other Roman artefacts from the lake are on display at the Bristol City Museum and Art Gallery. There are historic parks and mansion houses, including Stanton Drew, Hunstrete, Stowey House, Chew Court, Chew Magna Manor House and Sutton Court. Almost all of the villages have churches dating back to the fifteenth or sixteenth century. The area around Pensford was an important coal mining area during the nineteenth and early twentieth centuries when it formed part of the Somerset Coalfield, although there are no working coal mines today. The line of the now disused Bristol and North Somerset Railway runs south from Bristol crossing over the River Chew on the surviving distinctive Pensford Viaduct and on to Midsomer Norton. The area suffered serious flooding during the storm of 10 July 1968, prompting localised evacuation of populated valley areas in the lower parts of the valley, around Pensford and Keynsham.

The small fields in the western part of the area are particularly characteristic of the Chew Valley and date back to the most evident period of enclosure of earlier open fields which took place in the late medieval period. Fields of this category are generally small in size, regular in outline and often the boundaries preserve the outlines of the earlier strip field system. Regional variations in field size and pattern do occur. For example, there is evidence of medieval clearance of woodland on the slopes around Nempnett Thrubwell, south of Bishop Sutton and west and south of Chelwood. The annual mean temperature is approximately Seasonal temperature variation is less extreme than most of the United Kingdom because of the adjacent sea temperatures. The summer months of July and August are the warmest with mean daily maxima of approximately In winter mean minimum temperatures of or are common.]] Many of the large houses in the valley were built or bought by wealthy merchants from Bristol and Bath who employed local people in their households. Bess of Hardwick (1527–1606) is known to have lived in Sutton Court, Stowey, for a few years in the sixteenth century when, after the death of her first husband Sir William Cavendish, she married Sir William St. Loe, who was Chief Butler of England and captain of the guard to Queen Elizabeth, and owned several manors within the valley and surrounding areas. Around this period a close neighbour was Sir John Popham (1533–1607) who was a judge and the Speaker of Parliament. In the seventeenth century the eminent philosopher John Locke (1632–1704) lived in Belluton; his house is still known as John Locke's cottage. In the eighteenth century the poet John Langhorne (1735–1779) became the curate at Blagdon around the time that Augustus Montague Toplady (1740–1778) was the priest. Geologist William Smith (1769–1839) moved to the valley in 1791 to make a valuation survey of the Sutton Court estate and later worked for the Somersetshire Coal Canal Company. John Sanger, the circus proprietor, was born in Chew Magna in 1816. William Rees Mogg, former editor of The Times, took the title Baron Rees Mogg of Hinton Blewett in 1988. Jazz clarinettist Acker Bilk lived in Pensford. Dr Phil Hammond and wildlife television producer Richard Brock also live in the valley. In the past part of the population worked in coal mining, although there are no working mines in the area now. There is still a fairly large agricultural workforce and in light industry or service industries, although many people commute to surrounding cities for work. According to the 2011 Census the valley has a population of approximately 5,000, largely living in one of the dozen or so villages and in isolated farms and hamlets. The average age of the population is 42 years, with unemployment rates of 1–4% of all economically active people aged 16–74, however these figures are approximations because the ward areas covered and described in the census statistics do not relate exactly to the area of the valley. In the Indices of deprivation 2010 all of the areas within the valley were considered to be in the most affluent third in England.

The villages tend to have been built at the points where it was possible to cross the rivers and streams. Chew Magna is the business centre with a range of shops, banks etc. Other villages have local shops, often combined with post offices. Most villages have pubs and village halls which provide the majority of the social activity. The traditional building material is white Lias Limestone, sometimes incorporating red sandstone or conglomerate, with red clay tiled roofs. Buildings, particularly the churches, date back hundreds of years, for example those at Marksbury and Compton Martin, the latter incorporating a columbarium.

There are hundreds of listed buildings in the valley. Listing refers to a building or other structure officially designated as being of special architectural, historical or cultural significance. The authority for listing is granted by the Planning (Listed Buildings and Conservation Areas) Act 1990 and is administered by English Heritage, an agency of the Department for Digital, Culture, Media and Sport. Grade I covers buildings of exceptional interest, Grade II* particularly important buildings of special interest and Grade II buildings of special interest. Listed buildings in the valley include five churches dating back to the fourteenth century or even earlier, with grade I status: Church of St Andrew, Chew Magna, Church of St Bartholomew, Ubley, Church of St James, Cameley, Church of St Margaret, Hinton Blewett and the Church of St Michael the Archangel, Compton Martin.

Trains serve Keynsham railway station on the Great Western Main Line and Wessex Main Line with services provided by Great Western Railway and South Western Railway. Buses also connect with Bristol Temple Meads.

At the western end of the valley is the A38 and Bristol Airport, which means parts of the valley are on the flight path. The valley is also crossed by the A37 and they are joined by the A368. Most of the roads in the valley are small single track lanes with little traffic although a bottleneck often occurs within Chew Magna. The "Chew Valley Explorer" bus route 672/674 provided access to the villages in the valley. The nearest mainline railway station for most of the valley is Bristol Temple Meads. Cyclists can gain access via part of the Padstow to Bristol West Country Way, National Cycle Network Route 3. The Monarch's Way long distance footpath crosses the valley.

Chew Valley School is the main secondary school (11–18 years) for the valley. It is situated between Chew Magna and Chew Stoke. The latest (2011) Ofsted Inspection Report describes this specialist Performing Arts College as a mixed comprehensive school with 1,201 pupils on roll. The school is popular and oversubscribed with 226 students in the sixth form. The school has been successful in gaining a number of national and regional awards. There are state primary schools (4–11 years) in most of the local villages.

The local villages have football pitches and children's play areas. Gymnasium facilities, squash courts, badminton etc., and outdoor all weather pitches are available at the Chew Valley Leisure Centre between Chew Magna and Chew Stoke. There are a range of clubs and societies for young and old, including Scout groups, gardening society, and the Women's institute. There are areas in the valley which the Countryside Agency has designated as access land: Burledge Hill (south of Bishop Sutton) , Castle Earthworks (between Stowey and Bishop Sutton) , Knowle Hill (Newtown south of Chew Magna) , Round Hill (Folly Farm) and Shortwood Common (Litton)
A Bowls club is in Chew Stoke, cricket pitches and teams in Chew Magna and Blagdon. There are football teams in the valley including Chew Valley Football Club and Bishop Sutton F. C. The rugby club is based next to the leisure centre. The Bishop Sutton Tennis club is the largest in the valley, and there are also tennis clubs at Pensford and East Harptree. Both Chew Valley Lake and Blagdon Lake provide extensive fishing under permit from Bristol Water. The River Chew and most of its tributaries also have fishing but this is generally under licences to local angling clubs. Chew Valley Sailing Club is situated on Chew Valley Lake and provides dinghy sailing at all levels and hosts national and international competitions. Swimming is not allowed in the lakes and there are no swimming pools in the valley; however these are available locally in Bristol, Bath, Cheddar and Midsomer Norton. Each October the Chew Valley Arts trail takes place in venues around the valley during which over 50 local artists display their works in such media as painting, printmaking, sculpture, decorative glass, pottery, photography, jewellery and sugar craft. The valley and lakes have been an inspiration to artists and there is a small art gallery at Chew Valley Lake. Live music and comedy events take place in local pubs and village halls, with the village of Pensford holding a music festival every year.
