WL 23/95 Negligible, neutral, permanent Landscape Restoration Plan Moderate, beneficial, permanent 7.6 Historic Environment Existing Environment 7.6.1 There are no Scheduled Monuments, Listed Buildings, Conservation Areas or Registered Parks and Gardens or Registered Battlefields within the application site. The closest Scheduled Monument to the application site is Wick Barrow (also known as Pixies’ Mound) (see Figure 13). It is located 50m to the east of Wick Moor Drove. Wick Barrow dates from the Neolithic and Bronze Age periods and was partially excavated in 1907. Figure 13 Locations of Historic Environment Features 7.6.2 Geophysical survey and trial trenching confirmed that there are no buried archaeological remains within the application site. There are, however, a number of hedgerows within the application site that meet the archaeological and historical criteria of Important Hedgerows as defined in the Hedgerow Regulations 1997. There is one historic building, Benhole Barn, which dates from the late 18 th or early 19 th century. The barn has been extensively altered and is in a derelict state. 7.6.3 Undesignated heritage assets dating from the Mesolithic (10,000–3,500 BC), Neolithic (3,500-2,000 BC), Bronze Age (2,000-700BC), Iron Age (700BC-AD43), Roman (AD43- Hinkley Point C Preliminary Works Non Technical Summary Temporary Jetty Development 36 November 2010
AD450), Early-medieval (AD 450-AD1066), Medieval (AD1066-AD1540) and Postmedieval (AD1540 onwards) periods have been identified within the 500m study area around the application site (see Figure 13). 7.6.4 A foreshore survey undertaken in June 2010 confirmed that there are no surviving archaeological remains above the Mean High Water Mark. 7.6.5 Offshore, the UKHO wreck record for the study area contains 14 wreck sites. No protected wrecks were identified within the application site boundary. One apparent wreck site, located ~750m east of the application site boundary, reflected a ‘diffuser’ associated with the existing Hinkley Point Power Station Complex. Another potential wreck, identified from sidescan anomalies, lies 116m north-west of the edge of the application site boundary. It is not possible to offer a definitive interpretation of the type of wreck or wreckage that this may represent. No confirmed submerged archaeological remains have been identified in the area of the jetty development. 7.6.6 Lithological and stratigraphic modelling of deposits based on survey data from core logs collected in 2009 revealed a relatively consistent sequence across the survey area; ~1- 3m of surficial sands, gravels or clays, overlying a more consistent clay layer (0.5-5m thick) before reaching claystone bedrock. The discovery of peat deposits underlying the uppermost superficial deposits in 39 out of 63 vibrocores, and organic rich clays in a further 13 vibrocores, confirms the widespread presence of buried peats and other palaeo-landsurfaces, first identified in the western part of the survey area. These layers thin to the south-west of the survey area and only limited organic material has been identified in the core logs from the area of the jetty development. Main Predicted Impacts 7.6.7 During the jetty development it is considered that there is potential for a number of significant impacts to the historic environment. 7.6.8 The Scheduled Monument, Wick Barrow, is located to the east of the site and its setting would be partially altered during the construction phase as the area to the west would become a construction site. This would result in a moderate adverse impact. 7.6.9 The historic hedgerows would experience a high magnitude of impact during construction, which is assessed to be a moderate adverse impact. 7.6.10 Construction of the aggregates storage area would result in the complete removal of Benhole Barn, which would result in an overall adverse impact of moderate significance. 7.6.11 The buried peat and organic horizons below the soft sediments offshore are believed to be a relict Mesolithic landscape. The peat deposits may contain palaeo-environmental data such as pollen, macrofossil, insect remains and radiocarbon datable organics. Disturbance and removal of these horizons during construction works could cause a loss of research potential, and a moderate adverse impact. 7.6.12 The buried peat and organic horizons below the soft sediments offshore are believed to be a relict Mesolithic landscape. The peat deposits may contain palaeo-environmental data such as pollen, macrofossil, insect remains and radiocarbon datable organics. Disturbance and removal of these horizons during construction works could cause a loss of research potential, and a moderate adverse impact.
