Specification for a Scheme of Archaeological Works:

The Deposition of Dredged Silt from the River Ashop onto Adjacent Land at Alport Bridge, Derbyshire.

Non-technical summary

NMC Nomenca, acting on behalf of Severn Trent Water (STW), has been granted planning permission for the deposition of dredged silt from the River Ashop in Woodlands Valley, onto adjacent land at Alport Bridge, Derbyshire, centred on NGR SK 1385 8942.

An archaeological desk-based assessment of a 1.5km section of the River Ashop, conducted in 2012 concluded that the site has a moderate potential for Roman, medieval and post-medieval remains: evidence was found for two roads with possible Roman origins that traverse the river corridor. A prehistoric or Roman quernstone found adjacent to the site suggests the potential for further buried remains on the site itself.

The STW proposals for the site include the excavation of silt deposits from a short section of the river to the west of the Ashop Weir and their deposition on an adjacent area of riverbank. Further proposals include the reinforcement of eroding sections of the riverbank alongside the Ashop Aqueduct.

The current planning permission (Ref.: NP/HPK/0412/0381) is subject to an Archaeological Condition for a scheme of archaeological monitoring and recording during the proposed works. Pre-Construct Archaeological Services Ltd., have been commissioned by NMC Nomenca to prepare this specification, which has been formally approved by the Peak District National Park Authority (PDNPA).

1.0 Introduction 1.1 NMC Nomenca, acting on behalf of Severn Trent Water, has been granted planning permission by the Peak District National Park Authority (PDNPA), for the deposition of dredged silt from the River Ashop in Woodlands Valley, onto adjacent land at Alport Bridge, Derbyshire, centred on NGR SK 1385 8942 (Fig. 1).

1.2 An archaeological desk-based assessment of the site was conducted by PCAS Ltd in March 2012. The report concluded that the proposed silt deposition works would have archaeological implications. Based on the findings of the report, the Senior Conservation Officer for the PDNPA recommended an archaeological condition for a scheme of archaeological monitoring and recording during the proposed works.

1.3 Pre-Construct Archaeological Services Ltd., have been commissioned by NMC Nomenca to prepare this specification for a scheme of archaeological monitoring and recording during the silt deposition works. The document has been prepared in accordance with advice issued by the PDNPA Conservation Team and has been formally approved by them, prior to the start of groundworks in late August 2013.

2.0 Site location and description 2.1 The River Ashop and Woodlands Valley lie within the extensive civil parish of Hope Woodlands in the High Peak district of the Derbyshire Peak District. The small town of Edale lies c. 4 km to the south. The area referred to as ‘the site’, comprises the River Ashop diversion weir and a curved area of land on the southern riverbank to the west of the existing weir and diversion outlet, within the loop of the River Ashop (Fig. 2). To the north, the site is bounded by the river. To the east and west is the continuation of the river and river valley. To the south is the river’s flood plain below the slopes of Dean Hill.

3.0 Geology and Topography 3.1 Hope Woodlands lies within the geological region of the Dark Peak, an area of peat- covered, high hills dissected by deep, narrow valleys or 'cloughs'. The underlying solid geology of the Dark Peak is dominated by Upper Carboniferous shales and sandstones. To the west of Alport Bridge, in the area of the site, are the Kinderscoutian Mam Tor Beds otherwise known as the Mam Tor Sandstones. The Bowland Shale Formation comprising Mudstone, Siltstone and Sandstone is located further east, between the Alport / Ashop confluence and Rowlee Bridge.

3.2 The superficial drift deposits on the site are primarily Head, comprising Quaternary deposits of clay, silt, sand and gravel, with alluvial deposits are recorded in the valley bottom (http://mapapps2.bgs.ac.uk/geoindex/).

3.3 Topographically, the steep slopes of Hey Ridge lie above the site to the north; and the lower slopes of Dean Hill lie to the south. The area of the site is situated between c. 230m AOD and 250m AOD.

4.0 Planning background and heritage designations 4.1 In March 2012, the National Planning Policy Framework (NPPF) replaced PPS5. The NPPF places the responsibility for dealing with heritage assets affected by development proposals with the developer. Local planning authorities now need to be assured by those applying for planning permission that any such remains are not under threat. As a result developers are required to produce a definitive method of mitigating the effect of development on the historic environment within the planning process.

4.2 Section 12, paragraph 141 of the NPPF states that, ‘Local planning authorities should make information about the significance of the historic environment gathered as part of plan-making or development management publicly accessible. They should also require developers to record and advance understanding of the significance of any heritage assets to be lost (wholly or in part) in a manner proportionate to their importance and the impact, and to make this evidence (and any archive generated) publicly accessible. However, the ability to record evidence of our past should not be a factor in deciding whether such loss should be permitted’.

4.3 The NPPF includes utilities under its Infrastructure heading. Paragraph 162 of the NPPF stipulates that Local planning authorities should work with other authorities and providers to:

● assess the quality and capacity of infrastructure for transport, water supply, wastewater and its treatment, energy (including heat), telecommunications, utilities, waste, health, social care, education, flood risk and coastal change management, and its ability to meet forecast demands; and ● take account of the need for strategic infrastructure including nationally significant infrastructure within their areas.

4.4 Severn Trent Water adheres to the Code of Practice on Conservation, Access & Recreation (Water Industry Act 1991), whereby the Company is obliged to consider, and mitigate the consequences of its activities upon the archaeological resource.

4.5 The Local Planning Authority for the site is the Peak District National Park. Policy L3 of the Peak District National Park Core Strategy (2011) seeks to ensure that development conserves and, where appropriate, enhances or reveals the significance of archaeological, architectural, artistic or historic assets and their settings, including statutory designations. Development will not be permitted other than in exceptional circumstances where it is likely to cause harm to the significance of any such asset

4.6 On 30th May 2012, on the basis of the results of the March 2012 Archaeological Desk- Based Assessment, the Senior Conservation Officer for the Peak District National Park Authority (PDNPA) advised the LPA of the implementation of the following planning condition in association with Planning Application number NP/HPK/0412/0381:

A) No demolition/development shall take place/commence until a programme of archaeological work including a Written Scheme of Investigation has been submitted to and approved by the local planning authority in writing. The scheme shall include an assessment of significance and research questions; and:

1. The programme and methodology of site investigation and recording 2. The programme for post investigation assessment 3. Provision to be made for analysis of the site investigation and recording

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 5 PCAS Ltd., 2012: 917

4. Provision to be made for publication and dissemination of the analysis and records of the site investigation 5. Provision to be made for archive deposition of the analysis and records of the site investigation 6. Nomination of a competent person or persons/organisation to undertake the works set out within the Written Scheme of Investigation.

B) No demolition/development shall take place other than in accordance with the Written Scheme of Investigation approved under condition (A).

C) The development shall not be occupied until the site investigation and post investigation assessment has been completed in accordance with the programme set out in the Written Scheme of Investigation approved under condition (A) and the provision made for analysis, publication and dissemination of results and archive deposition has been secured.

4.7 The Planning Committee meeting of 13 July 2012 recommended that the application be approved subject to ten conditions, including archaeological condition 10 listed above. The committee concluded that the most appropriate form of investigation would be a watching brief to accompany the formation of the works compound and the stripping of topsoil prior to the deposition of silt. As such the proposal conforms with the requirements of Policy L3 of the Core Strategy.

5.0 Archaeological and historical background 5.1 The previous archaeological desk-based assessment (PCAS 2012) found a total of nine Derbyshire Historic Environment records listed within the 500m river corridor. The earliest records included a route known as the Doctor’s Gate, purported to be of possible Prehistoric or Roman origin, which crosses the river close to the area designated as the site compound. A quern stone, also of prehistoric or Roman date was found close to the southern boundary of the application area but no other prehistoric remains were recorded in the surrounding area.

5.2 No Saxon remains were identified within the study area and the closest known Saxon activity to the site is a reference to a 10th-century charter relating to the grant of lands in Hope Parish.

5.3 No medieval remains were identified within the study corridor, although the Doctor’s Gate road that traverses the site could possibly also have served as a pack-horse trail of medieval and later date. During the medieval period, the site probably formed part of the Royal Hunting Forest of High Peak and was protected from settlement by Forest Law.

5.4 Four post-medieval buildings and structures were identified within the study corridor, including the early 19th-century Rowlee Bridge; two mile-stones and a Methodist church to the northeast. However it was concluded that none of these structures will be adversely impacted by the silt deposition proposals. With the exception of a late 19th- century footbridge, no cartographic evidence was found for post-medieval activity anywhere on the site.

5.5 For the Modern period, an early 20th-century footpath sign, stone revetment walls and the modern weir infrastructure were identified, although these were not deemed as highly significant.

6.0 Aims and objectives of the project 6.1 The previous archaeological desk-based assessment (PCAS 2012) found that the site has a moderate potential to contain Roman, medieval and post-medieval archaeological remains. As a safeguard against disturbing unrecorded and/or undesignated archaeological remains; and in accordance with the archaeological condition (10) issued by PDNPA, the primary aim of the monitoring will be to allow the preservation by record of any archaeological features or deposits; and their subsequent assessment, analysis, interpretation, publication, dissemination and archiving.

6.2 The specific aims are:

To identify and record all archaeological deposits, features and artefacts exposed by the development works; To determine their form and function; To recover stratified dating evidence; To establish the sequence of any archaeological remains identified; To interpret any archaeological remains in the context of known archaeological remains in the vicinity and in the context of local and regional research agendas.

6.3 The archaeological monitoring of groundworks will be undertaken in accordance with the method statement detailed in Section 7.0 below. Should the methodology detailed in Section 7.0 prove essentially negative, it may be decided, in conjunction with the PDNPA Planning Archaeologist, to terminate the monitoring process prior to the completion of groundworks.

6.4 This document complies with the recommendations of: Procedures for the Transfer of Archaeological Archives. Museums in Derbyshire. Derbyshire County Council 2003; IFA Code of Conduct (1994 as revised); IFA Standards and Guidance for archaeological watching brief (2008); Management of Research Projects in the Historic Environment (MoRPHE); National Planning Policy Framework. Department for Communities and Local Government, March 2012.

6.5 Current research agendas and objectives for Derbyshire and the East Midlands (Knight et al 2012), that may be particularly pertinent to this site include:

Late Bronze Age and Iron Age (c.1150 cal BC–AD43): 4B Refine ceramic chronology by additional radiocarbon dating and typological analyses 4C Characterise the LBA-EIA settlement resource and investigate intra-regional variability 4E Assess the evidence for the evolution of settlement hierarchies; 4G Study the production, distribution and use of artefacts; 4I Prospect for Iron Age settlement in upland areas of the Peak District.

Romano-British (AD 43-c.410): 5B Support dissemination and synthesis of information on Roman finds; 5C Promote systematic application of scientific dating techniques;

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 7 PCAS Ltd., 2012: 917

5E Promote integration of studies of subsistence, diet and health; 5H Investigate landscape context of rural settlements; 5I Support research and publication of landscape syntheses; 5J Instigate regional scale characterisation study of industry.

7.0 Fieldwork methodology 7.0.1 Archaeological attendance and recording will take place during all intrusive groundworks associated with the silt deposition proposals. In accordance with the recommendations and condition issued by the PDNPA Conservation Team, the monitoring will entail intermittent or constant site attendance as appropriate and will be undertaken by suitably qualified/experienced professional archaeologists / PCAS Field Officers.

7.0.2 The STW proposals for the site include the excavation of silt deposits from a short section of the river to the west of the Ashop Weir (permitted development), and their deposition on an adjacent area of riverbank. Further proposals include the reinforcement of eroding sections of the riverbank alongside the Ashop Aqueduct. Groundworks on the site could therefore include any or all of the following:

Machine stripping of vegetation; Machine reduction of ground levels / topsoil from the area of the proposed silt deposition, site compound area or temporary stockpile area/s; Cut and cover works along the adjacent river bank to install mulch mats; Re-cutting and formalisation of the existing riverbank footpath.

7.0.3 All areas of vegetation- and topsoil stripping; silt deposition and intrusive groundworks will be accurately located on a 1:2500 or 1:1250 map of the area. In accordance with part B of the archaeological planning condition (No. 10) issued in association with Planning Application number NP/HPK/0412/0381, no demolition/development may take place on the site other than in accordance with the Written Scheme of Investigation approved under Condition 10A.

7.0.4 The Derbyshire Historic Environment Record (DHER) supports the Online Access to Index of Archaeological Investigations (OASIS) project. Before groundworks commence, an OASIS online record will be initiated (http://ads.ahds.ac.uk/project/oasis). When the project is completed all parts of the OASIS online form will be completed and submitted to the DHER.

7.0.5 In accordance with Derbyshire Museum guidelines, the receiving museum for Hope Woodlands/High Peak (Buxton Museum and Art Gallery), will be informed about the project at the earliest opportunity (prior to the commencement of fieldwork). A unique Derbyshire Museums accession number has been assigned in advance of the start of works (DERSB 2012.14). The landowner will also be contacted in order to reach an agreement in principle regarding the deposition of any finds with the museum.

7.0.6 Unless ground conditions (e.g. concrete or other rubble) dictate otherwise, all vegetation- and topsoil stripping will be conducted under archaeological supervision using a mechanical excavator fitted with a toothless bucket.

7.0.7 Following Health & Safety regulations, all archaeological deposits or features, including those revealed by machine will be manually cleaned and recorded. All

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 8 PCAS Ltd., 2012: 917

features exposed will be fully mapped at scale on an overall site plan, showing the locations of any groundwork excavations.

7.0.8 All archaeological deposits and features will be sample excavated, in order to establish their form, depth, character, date, state of preservation and extent, as well as to recover artefactual / ecofactual remains for further study. This process will typically require the following level of sampling:

• All structural remains (e.g., eaves drip gullies, beam slots and post-holes) will be fully or extensively excavated, and all relationships recorded. Any industrial features including any domestic ovens and hearths will be 100% excavated and sampled for analysis.

• All zones of specialised activity (e.g., industrial, agricultural processing, ceremonial, funerary) will be fully or extensively excavated and sampled for analysis, and all relationships recorded.

• All ditches, gullies and linear features: all significant relationships will be defined and investigated. All terminals and intersections will be excavated. Sufficient of the linear features will be excavated to determine the character of each individual linear feature over its entire course with consideration given to possible re-cutting of ditches which may not have taken place over the entire length. Generally this should mean sampling at 10m intervals in 1m wide sections. Linear features up to 5m in length will be a minimum 20% sampled. Should specialised deposits (e.g., localised refuse dumping, industrial wastes) be present, more extensive excavation will be required. Sufficient artefact assemblages will be recovered to assist in dating stratigraphic sequences and for obtaining sufficient ceramic assemblages for comparison with other sites.

• Pits will be generally half sectioned. Some pits may be full excavated in the light of information gained in half-sectioning. Pits containing significant structural traces or important artefactual or environmental material will be fully excavated.

• Post-holes and stake-holes where not clearly forming a structure will be half sectioned ensuring that relationships are investigated. Those features with a significant artefactual or environmental content will be fully excavated.

• Other features such as working hollows or quarry pits will be investigated to define their extent, date and function. All relationships will be defined.

7.0.9 The adequate recovery and recording of finds will be undertaken, combined with an appropriate sampling programme to provide environmental evidence from all archaeological deposits.

7.0.10 Spoil from topsoil stripping and silt from the deposition works will also be monitored in order to recover artefacts. This is to enable the identification and recording of any archaeological material that might be inadvertently excavated by machine.

7.0.11 The archaeologist monitoring the groundworks will cause the least possible disruption to the development programme, but at any time may request a pause in groundworks to assess any potential archaeology; and to allow the adequate hand excavation and recording of any features that have been identified. The archaeologist will keep the ground-workers informed of developments and progress.

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 9 PCAS Ltd., 2012: 917

7.1 Recording 7.1.1 The basis for field recording will be measured scale plans derived from plans supplied by the developer. All groundwork locations will be accurately plotted on the master plan, by triangulation or by EDM.

7.1.2 All archaeological deposits or features will be manually cleaned and recorded. Subject to health and safety considerations, the archaeologist will investigate archaeological deposits/features manually; the objective being to establish the form, depth, character and extent of features/deposits, as well as to recover artefactual / ecofactual remains for further study.

7.1.3 All artefacts will be treated in accordance with UKIC guidelines, First Aid for Finds (Watkinson & Neale 1998). All finds will be bagged and labelled according to the individual deposit from which they were recovered, ready for later cleaning, marking and analysis.

7.1.4 Any archaeological remains identified will be recorded by measured plan and section/elevation drawings at appropriate scales (normally 1:20 / 1:10 respectively). The heights Above Ordnance Datum (AOD) of archaeological and natural features and deposits will be recorded.

7.1.5 A written record of each significant stratigraphic horizon and archaeological feature will be made by single context on standard PCAS recording forms. These will be supplemented by the creation of a Harris Matrix and a narrative account in the form of a site diary.

7.1.6 A photographic record (in colour transparency and SLR digital formats) will be maintained during the course of the works and will incorporate an identification board, scales as appropriate and a directional arrow. Photographs will include:

the site before and during silt deposition works, showing specific stages including vegetation- and topsoil stripping; individual features and, where appropriate, their sections; groups of features, where their relationship is important.

7.1.7 The archaeologist will pay due attention to the landscape aspect of any exposed remains – both the cultural and the natural landscape, which may necessitate a rudimentary assessment to be made of neighbouring conditions (e.g. visible earthworks in adjacent areas, surface observation, standing buildings, vegetation cover etc). Such features will normally be recorded using PCAS General Account sheets, whereas archaeological deposits and features will be recorded using Context Record sheets.

7.1.8 Any dated archaeological deposits will be sampled for retrieval and assessment of the preservation conditions and potential for analysis of all biological remains. Any archaeological deposits considered suitable for environmental analysis will be sampled in 30-60 litre quantities, where possible.

7.2 Human remains 7.2.1 If human remains are encountered, they will not be excavated unless absolutely necessary and then, only once a Ministry of Justice Exhumation Licence has been

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 10 PCAS Ltd., 2012: 917

obtained. Such remains will be cleaned and recorded with minimal disturbance, left in situ and covered over. They will only be removed if leaving them in situ would render the development processes untenable, or if there are sound academic/scientific justifications for removal; and only once the PDNPA’s Conservation Team has been informed. The Police and HM Coroner will be informed if it is suspected that the remains have been buried for less than 50 years.

7.2.2 The archaeological contractor will comply with all reasonable requests of interested parties as to the method of removal, re-internment or disposal of the human remains or associated items. Every effort will be made, at all times, not to cause offence to any interested parties.

7.2.3 All work involving human remains will be carried out according to the standards and guidelines recommended by the British Association of Biological Anthropologists and Osteologists in conjunction with the IFA (Guidelines to Recording Human Remains, Brickley and McKinley (eds) 2004; COE / EH 2005; McKinley and Roberts 1993).

7.3 Environmental Sampling 7.3.1 Any dated archaeological deposits will be sampled for retrieval and assessment of the preservation conditions and potential for analysis of all biological remains. Any archaeological deposits considered suitable for environmental analysis will be sampled in 30-60 litre quantities, where possible. Where required, specialist advice (including the English Heritage Regional Science Advisor, if appropriate), on recording and sampling will be sought at the earliest opportunity (see list of specialists).

7.4 Treasure 7.4.1 All finds that qualify as ‘treasure’ under the 1996 Treasure Act (Treasure Act Code of Practice – 2002 revision) will be treated in accordance with the Act. If discovered during excavation, finds of gold and silver, or other finds legally defined as treasure, will be archaeologically removed to a safe place and the finds reported to the Coroner immediately (within 14 days). If the removal of such finds is not possible on the same day then adequate security arrangements will be made.

7.5 Health and Safety 7.5.1 All work will be carried out in compliance with the Health and Safety at Work Act 1974 and its related regulations and codes of practice. Employees and sub-contractors of Pre-Construct Archaeological Services Ltd will perform their duties in accordance with company safety policy (revised October 2011).

7.5.2 Where employees are temporarily engaged at other workplaces, they are to respect relevant local regulations, both statutory and as imposed by other employers within the Health and Safety at Work etc., Act (1974).

7.5.3 Site risk assessments will be prepared along the length of the silt deposition at each stage of the archaeological works, prior to any archaeological attendance and/or recording works taking place.

7.5.4 It should be noted that at the time of the previous site walkover survey of March 2012, the very western extent of the site (west of SK 13884 89480) and riverbank was not able to be surveyed due to dangerous, boggy conditions underfoot.

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 11 PCAS Ltd., 2012: 917

8.2 Stable finds (e.g. pottery, bone etc) will be washed, marked and packaged at PCAS prior to dispatch. Unstable finds will be dispatched for remedial conservation as a prelude to assessment, and bulk samples will be dispatched for processing.

8.3 Any finds and/or samples (bulk soil samples) will be dispatched to appropriate specialists for identification, analysis and assessment/reporting.

9.0 Reporting procedure 9.1 Following receipt of specialist accounts/archive reports, a fully illustrated and appended text will be prepared in accordance with current guidelines. Copies of this report will be submitted to the commissioning body, the PDNPA, the Derbyshire HER and the receiving museum for Hope Woodlands/High Peak (Buxton Museum and Art Gallery). The written account will include the following minimum information:

Accession number (DERSB 2012.14); a 1:10,000 site location map section, cross-referenced to the national grid a development location plan at an appropriate scale showing the location of all monitored groundworks, and incorporating the location and orientation of any archaeological features exposed; individual plan and section drawings, normally at 1:10 and 1:20 scales; captioned colour plates; full specialist descriptions and/or reports; an integrated account of the archaeological methodology and results, incorporating an assessment of the significance of the findings; a critical and unique review of the effectiveness of the methodology; Specialist artefact and environmental reports, as necessary, with reference made to appropriate published type-series; References.

10.0 Publication and dissemination 10.1 In order to place the results of this scheme in the wider public domain, the results of the investigation will be made public as follows:

A copy of the resulting report will be presented to the Derbyshire HER so that results can be incorporated into their records and databases.

As part of the reporting process, the data will be entered on the On-line Access to the Index of Archaeological Investigations (OASIS entry). The OASIS online record will be initiated before fieldwork commences.

10.2 In accordance with PDNPA requirements, if required, provision will also be made for a summary of the results to be published in an appropriate local journal, such as the Derbyshire Archaeological Journal. Should the monitoring reveal finds of regional or national importance, provision for publication will be made in an appropriate regional or national journal.

11.0 Archive preparation and deposition 11.1 The entire archive will be prepared at the offices of PCAS. The report will be prepared, and two copies deposited with both the PDNPA Conservation Team and the Derbyshire Historic Environment Record, within six months of completion of the

WSI: Deposition of Dredged Silt from River Ashop onto Adjacent Land, Alport Bridge, Derbyshire. 13 PCAS Ltd., 2012: 917

archaeological works. The report will acknowledge any input by the PDNPA, the curatorial role of the Museum and will include a reference to the accession number for the archive (DERSB 2012.14).

11.2 The site archive will be deposited with the receiving museum for Hope Woodlands in High Peak (Buxton Museum and Art Gallery), within a timescale agreed between PCAS Ltd., and the Museum. Ideally this will be within twelve months of the completion of site works for sites not requiring publication. In the event that highly significant archaeology is found and funds are obtained for a detailed publication, the Museum will be kept informed of any anticipated delay in deposition. The Museum will also be informed of the progress of the project through any subsequent stages of mitigation. The Museum will also be informed in writing if responsibility for the project is transferred to a different archaeological unit for any reason. Depending upon the start date and completion of the silt deposition works, transfer of the archive to Buxton museum is therefore anticipated in late 2014 / early 2015, under the unique accession code DERSB 2012.14.

12.0 Copyright 12.1 Working under the terms of the Copyright, Design and Patents Act 1988, PCAS shall retain full copyright with regard to written, digital and graphic material. However, following project completion, the commissioning body, the PDNPA, the Derbyshire HER, and the Archaeology Data Service may, in the interest of informing and advancing the profession, make responsible use of the data, provided that any material copied or cited in reports is duly acknowledged and all copyright conditions observed.

13.0 Timescale 13.1 The proposal involves spreading 5725m³ of material over an area of approximately 0.5 ha to an average depth of 800mm. It is anticipated that the proposal will take 6 weeks to complete once the development is commenced, allowing a three month period for the development will allow sufficient time to complete the works and prevent potential long-term impacts. The timescale for the archaeological attendance and recording is therefore in the region of 6 to 12 weeks but will ultimately be governed by the site contractors’ timetables. The silt deposition works will commence in late August 2013. This document has been formally approved by the Senior Conservation Officer for PDNPA, who has been notified of the start of works.

14.0 Monitoring arrangements 14.1 Internal monitoring will be the responsibility of the PCAS Director. The Senior Conservation Officer for PDNPA will be responsible for monitoring progress and standards throughout the project, to ensure that fieldwork and all aspects of post- fieldwork meet the approved specification.

14.2 In accordance with any standard archaeological planning condition issued, the Conservation Team at PDNPA will be given at least fourteen days’ advance notice of when work is due to commence and will be free to visit the site by prior arrangement (subject to the agreement of the commissioning body). Thereafter, all phases of archaeological work shall be completed in accordance with the PDNPA approved version of this Written Scheme of Investigation (WSI).
