1.2 Objectives
1.2.1 The proposed development comprises of 141 residential dwellings and is being developed with consent from East Riding of Yorkshire Council.
1.2.2 Near surface made ground has been found to contain contaminants above residential GACs. Elevated lead has been recorded at a single location (TP15) and elevated PAH in three locations (TP06, TP15 and BH06). The recorded concentrations may present a potential risk to end users if present within surface soils of the finished development. As such remediation has been recommended to minimise potential risks to human health during normal site occupancy and use following redevelopment.

2 SITE DETAILS AND DESCRIPTION
2.1 Site Location
2.1.1 The site is located to the north-west of Hull, approximately 8km from the city centre and is centred at approximate National Grid Reference (NGR) 501769mE 430501mN. The site has an overall area of approximately 3.72 hectares, with the site location shown on Figure 40714/001.
2.1.2 The site is roughly rectangular in shape and comprises a number of differing land uses including soft landscaping, existing residential property, and a number of outbuildings. The site slopes steadily from the south to the north, at a similar level to the surrounding land. Access to the site is currently off Great Gutter Lane West to the north.
2.2 Site History
2.2.1 A full record of the historical period reviewed is presented in the combined Phase I/II report carried out by Alan Wood and Partners. A summary of significant findings is presented below.
2.2.2 The earliest available Ordnance Survey historical maps, dated c.1855 show the site to have been situated in an area of undeveloped agricultural land. The site was developed as residential properties c. 1961.
2.2.3 Anecdotal evidence indicates that the site has historically been used as pastoral farmland.
2.2.4 The adjacent land surrounding the site has been predominantly developed as residential properties. A shopping park was constructed to the north of the site (250m) c. 1994.

3 GROUND CONDITIONS
3.1.1 Reference should be made to the Alan Wood and Partners Phase I/II Geo- Environmental Investigation Report (Appendix A) for full details of the ground conditions encountered.
3.1.2 A summary of the ground conditions that prevail on site is given below. Reference should be made to the document referenced above for details of strata encountered at specific locations.
3.1.3 Made Ground: Isolated and discontinuous thin deposits of made ground were encountered at four locations (BH1, BH2, BH4, BH6, BH12, TP06, and TP15) to a maximum depth of 0.50mbgl. This material generally comprised deposits of gravelly sand, with concrete, brick and chalk inclusions. A deposit of re-worked superficial soils with brick and chalk inclusions was encountered at the north-eastern site boundary.
3.1.4 Natural Strata: The near surface superficial deposits comprised a firm to very stiff, cohesive Devensian Till with a varying granular chalk component. Chalk bedrock was encountered at between 0.70m bgl (BH11) and 4.00m bgl (BH6).
3.1.5 Burnham chalk was encountered below the cohesive glacial deposits within all of the windowless sampler boreholes and within trial pits TP4 to TP7 and TP11 to TP27. The upper layers of the chalk were noted to be fully weathered to a gravely clay (Weathering Grade V) and to become gravelly and stronger with depth (Weathering Grade IV).
3.1.6 Groundwater: Perched groundwater was encountered at 1.60m in BH5 during the investigation. During subsequent monitoring, minimal water was recorded within BH2 and BH6 in the base of the borehole, between 4.94m and 5.00mbgl. The observed water is considered to be localised perched water within the glacial deposits rather than a continuous groundwater body.
3.2 Visual & Olfactory Evidence of Contamination
3.2.1 No visual or olfactory evidence of gross contamination, such as hydrocarbons, was recorded during the ground investigation.

4 IDENTIFIED CONTAMINATION ISSUES
4.1 Introduction
4.1.1 Alan Wood and Partners carried out testing on nine soil samples recovered from the site for a general suite of potential contaminants based on the site’s known former and current uses. An additional two samples were submitted for leachate testing to assess the potential for contaminant migration to controlled waters receptors.
4.1.2 Assessment of the soils data indicated that there are elevated concentrations of lead that exceed residential with plant uptake generic assessment criteria (GAC) in one location on the site (TP15) within the made ground. As the recorded concentration exceeds the adopted GACs, it has been deemed to represent a potential risk to end users of the proposed residential development.
4.1.3 Seven of the tests on soil samples and four of the tests on leachate samples analysed for PAH, TPH, BTEX or MTBE recorded concentrations above relevant GAC's. Increased level PAH concentrations were measured within samples of made ground recovered from TP06, TP15 and BH06. Potential risk to human health in a residential with plant uptake land use scenario with respect to organic contaminants was identified associated with localised made ground found in BH6, TP06 and TP15.
4.1.4 A total of 9 no. soil samples were analysed. No asbestos fibres were detected in the samples tested. Risk associated with asbestos containing materials is therefore not anticipated.

5 RISK ASSESSMENT
5.1 Introduction
5.1.1 Current UK legislation on contaminated land is principally contained in Sections 78(A) to (YC) in Part 2A of the Environmental Protection Act 1990, which was retrospectively inserted by Section 57 of the Environment Act 1995. The Contaminated Land Regulations 2000 were amended in 2005. The Environmental Protection Act 1990: Part 2A Contaminated Land, Statutory Guidance, Edition 2, 2006, promulgates the revised statutory guidance with respect to the operation of the Contaminated Land Regime following the implementation of the Contaminated Land Regulations, 2005.
5.1.2 The definition of contaminated land is central to the operation of Part 2A. Legislation adopts the principle of a 'suitable for use' approach for the assessment of contaminated land, the rationale reflected in the site-specific risk assessment and determination of remedial strategy. Action is only required if unacceptable risks are posed to human health or to the environment, taking into account the current land use and geo- environmental setting.
5.1.3 The legislation places a responsibility on the Local Authority to determine whether the land under its jurisdiction is contaminated by consideration of whether:
• Significant harm is being caused; • There is a significant possibility of significant harm being caused; • Significant pollution of controlled waters is being caused or is likely to be caused.
5.2 Assessment Framework
5.2.1 The statutory guidance describes a risk assessment methodology in terms of ‘significant contaminants’ and ‘contaminant linkages’, using ‘source-pathway-receptor’ scenarios for the site. Contaminant linkages are formed when there is a linkage between a contaminant source and a receptor by means of a pathway. Each element has to be present, or no linkage can be formed.
5.2.2 Risk assessment and the procedure of identifying sources, pathways and receptors is recognised as an approach to determine the extent and significance of contamination either within the context of Part 2A (when assessing current site status or when considering the acquisition of an existing development) or the planning process (for the redevelopment of an existing site, or when considering the acquisition of a site for

Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
redevelopment purposes). Either way, the ‘suitable for use’ approach is adopted when assessing risk and the source-pathway-receptor assessment defines the conceptual model for the site.
5.2.3 Within the context of this report therefore, the risk assessment has been undertaken on the basis that the ‘suitable for use’ approach remains aligned with the site being redeveloped for the end uses given above.
5.3 Summary of Identified Contaminant Linkages
5.3.1 On the basis of the ground investigation and laboratory test results, contaminants have been identified which present a potential risk to site end users. Without remedial measures potential localised risks are considered to be moderate through direct exposure to contaminated soils.
5.3.2 The highlighted risk to human health applies to the gardens and landscaped areas.
5.3.3 A summary of the conceptual site model is presented in Table 5.1.

6 CONTAMINATION REMEDIATION OPTIONS
6.1 Protection of Human Health in the Post-Development Case
6.1.1 Potential contaminant linkages to the site end-user in the post-development case principally comprise dermal contact (with soil and soil-derived dust), dust inhalation (indoor and outdoor), ingestion (direct and indirect soil ingestion) and uptake by homegrown produce.
6.1.2 To identify potential remediation options and assess their viability against the potential risks posed to site end users and remediation requirements and options appraisal has been carried out. This study presents an assessment of potentially applicable remediation techniques for the identified contaminant linkages and ascertains (qualitatively) their potential viability for the site.
6.2 Options Appraisal
6.2.1 In accordance with guidelines presented in the Land Contamination Risk Management; Stage 2 Options Appraisal (October 2020), the following options appraisal has been carried out to determine the most effective method of managing the site and the identified relevant contaminant linkages given above.
6.3 Remediation Objectives
6.3.1 The following objectives relating to the reduction/control of the risks associated with one or more of the linkages, have been identified:
• Protect end users from harm either by removing the source or breaking the exposure pathway;
• Protect the wider environment.
6.3.2 In selecting feasible remediation options, the following factors are considered.

6.4 Feasible Remediation Options
6.4.1 The following section identifies remediation options that could be utilised to effectively manage the identified relevant contaminant linkages, given that the site is to be redeveloped for a residential (with plant uptake) end use.
6.4.2 In determining the most effective remediation option for a site, consideration needs to be given to a number of techniques, stating (where appropriate) the suitability and limitations of each chosen method. On the basis of the identified contaminant linkages and remediation objectives, the following options have been considered.

6.4.4 On this basis, there are two viable options for remediation of the isolated hotspots on site.
6.4.5 The contaminated soils could be removed from their current location and re-used below either the proposed POS or, as it is understood that levels are to be adjusted across the

Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
site to achieve the required development levels, the contaminated soils could be incorporated as part of the proposed cut and fill works in deeper layers.
6.4.6 The areas of identified contamination are located on the northern edge of the site (BH6), towards the centre of the site (TP06), and towards the southern edge of the site (TP15). The base of the affected material was recorded as being 500mm (BH6), 100mm (TP06), and 200mm (TP15) below existing ground level.
6.4.7 Given the shallow nature of the identified contamination, soil capping may also be an option for remediation. A minimum of 600mm of suitably clean capping is required over the contaminated soils.
6.4.8 Any imported material proposed for use as capping should be validated through further environmental laboratory analysis prior to importation or placement in accordance with YALPAG Guidance for Verification Requirements for Cover Systems, Version 3.4, November 2017.
6.4.9 No potential risks relating to hazardous ground gases have been identified by the investigations to date, which included ground gas monitoring, and as such no remedial measures in the proposed buildings are required.

7 REMEDIATION STRATEGY
7.1 Scope of Works – Removal and Re-use
7.1.1 The affected made ground material could be removed and re-used to re-engineer fill material beneath either the proposed POS, or within the deeper areas of fill required as part of the site regrading.
7.1.2 This should be done in accordance with the requirements of CL:AIRE Definition of Waste Development Industry Code of Practise and a materials management plan developed to ensure materials are managed within this framework.
7.1.3 Although subject to site-specific constraints, it is envisaged that the following works will be undertaken.
NOTE: all proposals will need to be agreed with the Local Authority beforehand.
Phase I - Site Clearance
7.1.4 Site clearance in the affected areas (around BH6, TP06 and TP15) will need to be completed. The affected soils are found within the upper layer of made ground (up to 500mm below existing ground level).
7.1.5 The removal of any existing structures, along with any existing hard-standing (e.g. concrete and tarmac), sub-structures/pits and any remaining ground slabs or old foundations should be completed to their full depth.
7.1.6 Should further currently unidentified contamination sources be exposed during site clearance works, these areas will also be subject to risk assessment/remediation.
Phase II – Excavation and re-use of existing made ground
7.1.7 It is proposed that contaminated material is excavated from the area of BH6, TP06 and TP15 and re-used as part of the engineered fill either below the POS or within deeper areas of fill. The material is granular and if placed at depth within the engineered fill, there is no potential risk of end users being exposed to the identified contamination during normal post development use of the site.
7.1.8 The made will be excavated from the area of BH6, TP06 and TP15 and from an area 25m2 (5m x 5m) around the affected locations. The sides and base of the excavation
Report Prepared for Beal Homes 16
Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
will have samples recovered for laboratory analysis to confirm no contamination remains.
Excavated material from the area of BH6, TP06 and TP15 shall be placed on an impermeable membrane with surrounding bunding to prevent run off while the laboratory testing confirming the limits of the excavation are free from contamination have been received. The excavation of the area of POS or preparation of the deeper fill areas should then be completed.
Phase III – Placement of Engineered Fill
7.1.9 Following excavation of the unsuitable made ground in the vicinity of BH6, TP06 and TP15, unsuitable material shall be removed and oversized material either removed or processed to a suitable size (<125mm diameter), if necessary.
7.1.10 Where contaminated material is to be placed within the fill works, this should be placed at the base of the deeper filling works to ensure a suitable cover of clean material (>600mm). Materials shall be placed and compacted to a method to suite the material grading and in accordance with the Specification for Highways Works Series 600.
7.1.11 Where the material removed from the excavations around BH6, TP06 and TP15 is to be placed below the POS, over excavation may be required to ensure the material is placed at sufficient depth to achieve adequate protective cover above.
7.1.12 The Earthworks design has concluded that there is a requirement for import of material on site to be required for the engineered fill.
7.1.13 Appropriate validation testing of placed fill shall be undertaken in accordance with an approved earthworks specification for the site to confirm that material compaction is adequate and the placed fill meets the specified performance criteria.
Report Prepared for Beal Homes 17
Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
7.1.14 Phase IV – Verification and Reporting
7.1.15 Given that remediation measures are required at the site for the protection of human health it will be necessary to prepare a validation report to show that remediation measures have been completed, that contamination issues have been successfully addressed and that material has been managed in the agreed way. Following completion of the remediation works therefore, a validation report will be submitted to the Local Authority for approval and in support of the application to discharge planning conditions and CL:AIRE.
7.1.16 A verification report for all remedial works will be prepared by a suitably qualified, experienced Environmental Engineer in accordance with the requirements of the local regulatory requirements, YALPAG and CL:AIRE.
7.2 Scope of Works – Engineered Capping
Phase I - Site Clearance
7.2.1 Site clearance in the affected areas (around BH6, TP06 and TP15) will need to be completed. Where the site levels are to remain unchanged or similar to existing, a reduce level dig will be required to accommodate the capping. This may remove the affected material entirely as the affected soils are found within the upper layer of made ground (up to 500mm below existing ground level).Where the base of the affected material is reached, no capping is required and levels should be reinstated with clean soils. As mentioned in Section 7.1.8, validation samples of the formation following excavation will be required to ensure all affected material has been removed.
7.2.2 The removal of any existing structures, along with any existing hard-standing (e.g. concrete and tarmac), sub-structures/pits and any remaining ground slabs or old foundations should be completed to their full depth.
7.2.3 Should further currently unidentified contamination sources be exposed during site clearance works, these areas will also be subject to risk assessment/remediation.
Phase II – Placement of Capping
7.2.4 It is proposed that contaminated material is left in situ, within the vicinity of BH6, TP06 and TP15, and engineered capping (>600mm) is placed over the top of the
Report Prepared for Beal Homes 18
Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
contaminated material. Capping will ensure there is no potential risk of end users being exposed to the identified contamination during normal post development use of the site.
7.2.5 Phase IV – Verification and Reporting
7.2.6 Given that remediation measures are required at the site for the protection of human health it will be necessary to prepare a validation report to show that remediation measures have been completed, that contamination issues have been successfully addressed and that material has been managed in the agreed way. Following completion of the remediation works therefore, a validation report will be submitted to the Local Authority for approval and in support of the application to discharge planning conditions and CL:AIRE.
7.2.7 A verification report for all remedial works will be prepared by a suitably qualified, experienced Environmental Engineer in accordance with the requirements of the local regulatory requirements, YALPAG and CL:AIRE.
Report Prepared for Beal Homes 19
Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
8 GENERAL CONSIDERATIONS
8.1 Site Safety
8.1.1 The Project Manager on site will retain the Health and Safety Documents. The document, 'Protection of workers and the general public during the development of contaminated land' will also be held on site. The guidance, standards and legislation followed will include the CDM Regulation (1994), HSW Act (1974) and COSHH Regulations (1988).
8.2 Hazards Posed by the Principal Contaminants
8.2.1 The principal contaminants of concern that are known to exist locally in the made ground soils are Lead and PAH (Benzo(a)anthracene, Benzo(b)fluoranethene, Benzo(a)pyrene, and Dibenzo(a,h)anthracene).
8.2.2 Lead is a chronic toxicant, which means toxic effects are generally observed following chronic (long term) exposure.
8.2.3 Toxic effects following acute exposure are observed for very high lead levels. Following acute exposure to high levels of lead effects on the gastrointestinal (GI) system, nervous system, haematopoietic system and on renal function are observed. Colic is a common early sign, with encephalopathy being characteristic of very high level exposure; children are more sensitive to these effects.
8.2.4 Chronic exposure results in neurological effects such as reduced nerve conduction velocity, postural sway, tremor, amyotrophic lateral sclerosis, and intelligence and neurobehavioral effects in children and adults. The developing brain and nervous system appears to be more vulnerable to the effects of lead. Chronic lead exposure may also cause anaemia. It may also affect renal function. Similarly lead causes cardiovascular toxicity, the critical endpoint being increased systolic blood pressure. These endpoints are considered the most sensitive in adults. Chronic exposure to lead may cause adverse effects on both male and female reproductive functions. Chronic exposure to lead during pregnancy has been associated with adverse outcomes including miscarriage, premature birth, foetal growth restriction, neurodevelopmental delay and maternal hypertension.
8.2.5 Benzo(a)pyrene is considered to be one of the most toxic PAHs. Inhalation and skin absorption are the main routes of occupational exposure to PAHs, resulting in decrease
Report Prepared for Beal Homes 20
Remediation Strategy Address: Proposed Residential Development Phase 2 on Land off Beverley Road, Willerby Project Number: SLR/AC/40714-Rp004
in lung function, chest pain, respiratory irritation, cough, chronic dermatitis, depressed immune system, and cancer of the skin and lungs. Studies show a dose-response relationship between exposure to PAHs during pregnancy and effects related to intrauterine growth restriction.
8.3 Health and Safety
8.3.1 All parties involved in groundworks will be required, as a minimum, to adhere to basic health and hygiene precautions, as groundworks may bring personnel and others into direct contact with the ground, potentially exposing them to harmful contaminants via the pathways of ingestion, inhalation and skin contact.
8.3.2 The site ground works will, therefore, be inspected by experienced personnel who will ensure that appropriate Health and Safety and good site management procedures are adopted throughout. Such procedures should be based upon published guidance, such as provided within the HSE document “Protection of Workers and the General Public During the Redevelopment of Contaminated Land”.
8.4 Unsuitable Materials
8.4.1 The Contractor shall ensure that machine drivers and supervisory personnel shall closely observe the formation for unusual materials such as: odorous solids or liquids, friable, fibrous or 'dusty' material, in particular asbestos accumulations or seepages of liquids which are:
• Tarry or oily; • Fuming or bubbling; • Coloured materials exhibiting any changes in colouration of the ground materials after exposure or excavation.
8.4.2 Upon discovering any unusual materials work at that position shall stop and the Engineer shall be informed immediately.

EXECUTIVE SUMMARY
Site Location & The site is located off Great Gutter Lane West, Willerby and is centred at Description approximate National Grid Reference (NGR) 501769mE, 430501mN.
The site comprises an approximately rectangular parcel of land which is currently used as mixed residential and agricultural usage. At the time of the works, the site was divided into five separate parcels of land (Webb, Bradley, Swift, Robinson, and Murry). Historical Land Use The earliest available Ordnance Survey historical maps, dated c.1855 show the site to have been situated in an area of undeveloped agricultural land. The site was developed as residential properties c. 1961. Anecdotal evidence indicates that the site has historically been used as pastoral farm land. The adjacent land surrounding the site has been predominantly developed as residential properties. A shopping park was constructed to the north of the site (250m) c. 1994. Geology Superficial deposits are recorded as Devensian Till. Bedrock is recorded as the Burnham Chalk Formation. Hydrogeology Superficial deposits are recorded as ‘Secondary A’ Aquifer. Bedrock is recorded as ‘Principal’ Aquifer. Mining Assessment The site is not in a Coal Authority ‘Coal Mining Reporting Area’, or ‘Development High Risk Area’. Risk associated with coal mining is therefore considered to be negligible. Geotechnical Hand shear vane test results, recorded during the site investigation works Assessment produced a range of corrected undrained shear strengths ranged from 133N/m2 to 188kN/m2. The mean and median undrained shear strengths were calculated as 181kN/m2 and 188kN/m2 and are generally indicative of high strength soils in accordance with Table 6 of BS EN ISO 14688-2:2018.
The calculated modified plasticity index (NHBC Chapter 4.2) was found to be between 15% and 31%, which is equivalent to a low to medium volume change potential, according to the NHBC guidelines. The highest recorded worst-case VCP (medium) should be adopted for design purposes however to allow for variation in ground conditions across the development area. Environmental Elevated contaminants were found in made ground samples, in both soil Assessment and leachate tests, taken from TP06, TP15, and BH06.
Assessment of the soils data indicates that there are elevated concentrations of lead that exceed relevant GAC criteria in one location on the site (TP15) within the made ground. Seven of the tests on soil samples and two of the tests on leachate samples analysed for PAH, TPH, BTEX or MTBE returned concentrations above relevant GAC's.
It is recommended that contaminated made ground be removed and replaced with suitable clean fill, or capped to ensure it is in excess of 600mm below finished ground level beneath gardens. Foundations It is considered, where competent undisturbed natural strata is encountered at founding depth that, for structures of typical construction, traditional deep strip, trench-fill or pad foundations should be suitable. Where ground disturbance is encountered during construction, an assessment of the ground and its implication on foundation design will need to be undertaken. Some ground improvement may be required with foundations being suitably strengthened/reinforced or an alternate foundation solution being implemented. Ground Slabs Ground bearing slabs could be used where ground conditions allow and no precautionary measures associated with soft and unstable soils are required.

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Precautions near A number of mature silver birch (low), maple leaf (moderate), conifer, oak Trees (high) and pine trees (moderate). The identified trees have a range of water demand levels ranging between low water demand to high water demand. The calculated plasticity index has been calculated at between 15% and 31%, which is equivalent to a low to medium volume change potential. However, the highest recorded VCP (medium) should be adopted for foundation design. Foundations can be reduced by 0.15m (150mm) due to allowances made for the climate at the site location.
The minimum foundation depth within the influence of trees with a moderate VCP and moderate or water demand is 0.90m bgl (0.75m), and 1.00m (0.85m), respectively.
In addition, precautions would be required where trees are to be removed or where new planting is proposed. All foundations should be constructed in accordance with NHBC Standards (i.e. Chapter 4.2). Drainage The cohesive superficial deposits are not suitable for soakaway drainage. Based on observations made during a preliminary soakaway drainage test, completed on 12th April 2018, the Burnham Chalk Formation is not considered to be suitable for soakaway drainage for the site. Therefore, surface water will need to be discharged into the local system, subject to obtaining the necessary consents and approvals. Sulphate Design Sulphate classification of DS-1 should be suitable along with an ACEC class of AC-1s. However, this does not make any necessary allowance for the requirements of structural strength, or requirements for durability of concrete. Further consultation should be made with the designing engineer with respect to the site specific sulphate resistant concrete to be used. Potable Water Risk to potable water supply pipes is considered to be low. On the basis of Supplies available test results it is unlikely that protective measures will be required. Consultation should however be undertaken with the local water authority with respect to any precautions they may require, prior to construction. Obstruction & Localised obstructions to excavations or shallow hard rock are not Excavations anticipated given the geology and lack of previous development. Boundary Conditions Where excavations are proposed close to site boundaries and there is the possibility of weak/unstable ground passing across that boundary and beneath adjacent structures, a risk assessment of the integrity/stability should be undertaken prior to such works being carried out. Designed and engineered temporary/permanent measures should be adopted to ensure their continued stability where necessary. Roads No in situ CBR testing has been carried out to date as the final development levels at the site are unknown. On the basis of visual observation, it is considered that the near surface soils are likely to have a minimum CBR value of around 3.0%, perhaps higher, but this should be confirmed. Further Works Soakaway drainage testing Plot specific foundation design Watching brief during demolition works NB. The Executive Summary presented above is an overview of the key findings and conclusions of the report. There may be other information contained within the body of the report which puts into context the findings of the Executive Summary. No reliance should therefore be placed on the Executive Summary until the report as a whole has been read in full.

1.4.1 The scope of works undertaken as part of this appraisal was to:
Carry out a physical inspection of the site (walkover survey): Report Prepared for Beal Developments Ltd and HSBC Bank Plc 7
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Review any pre-existing documentation relating to ground conditions (geotechnical and environmental); Investigate the ground conditions present on-site and identify their geotechnical properties in relation to the site's proposed end use; Investigate the hydrogeological regime beneath the site wherever possible; Investigate the potential risks to the development from hazardous ground gas sources (to be reported under separate cover); Identify the nature and concentration of any contamination within the on-site soils and undertake a tiered risk assessment to establish likely risks to sensitive receptors. Defining a Conceptual Site Model of potential contaminant linkages relevant to the proposed redevelopment of the site; Provide preliminary advice in relation to any environmental or geotechnical issues associated with the site including foundation recommendations and other recommendations needed to facilitate the proposed redevelopment, including, where necessary, identifying any additional phases of work or remediation that need to be carried out.
1.5 Site Works
1.5.1 The findings and recommendations given in this report are based on fieldwork undertaken between Thursday 19th July and Tuesday 24th July 2018, comprising 27No. mechanically excavated trial holes and 12No. windowless sample boreholes.
1.6 Limitations of Study
1.6.1 This report presents factual and interpretative geotechnical and environmental information, along with provisional construction proposals and recommendations relevant to the objectives of the investigation for the site end-use given above. The report has been prepared for the titled project and Alan Wood and Partners can accept no responsibility or liability for the consequences of the use of this document, wholly or in part, for any other purpose than that for which it was commissioned.
1.6.2 For the purposes of this report and thus defining risk to the proposed development from an environmental point of view, a 'residential' end use scenario has been adopted. Interpretation and recommendations should not be assumed valid for alternate land uses. Where the proposed site usage changes, the findings of this report should be re-assessed to accommodate the change in proposed end-use. Report Prepared for Beal Developments Ltd and HSBC Bank Plc 8
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
1.6.3 The conclusions and recommendations presented in this report are based on site- specific information obtained during the desk study, ground conditions encountered and laboratory analysis and are considered reasonable on the basis of available information at the time the assessment was carried out. They should not necessarily be relied upon to represent site conditions at a substantially later date.
1.6.4 The findings and opinions provided in this report are given in good faith and are subject to the limitations and constraints imposed by the methods and information sources described. Factual information has been obtained from a variety of sources. Alan Wood and Partners assumes that third party data is reliable, but has not independently confirmed this. The validity and accuracy of this information is therefore outside the control of Alan Wood and Partners. Professional judgement and experience is however used to ensure that uncertainties are reduced to a level appropriate to the site conditions, the purpose of the investigation and the resources devoted to it by the Client.
1.6.5 Whilst every effort has been made to carry out an assessment that enables a realistic characterisation of the geotechnical and environmental parameters at the site, the possibility of significant spatial variation in actual ground, groundwater and environmental (gas and contamination) conditions existing between or beyond exploratory hole locations cannot be discounted. Where information or opinion is given this is for guidance only. Further information, ground investigation, construction activities, change of site use or the passage of time may reveal conditions that were not indicated in the data and therefore could not have been considered in the preparation of this report. Where such information might impact upon stated opinions, Alan Wood and Partners cannot accept responsibility for conditions not encountered and reserves the right to modify or retract the opinions expressed in this report. Where opinions expressed are based on current available guidelines and legislation, no liability can be accepted by AWP for the effects of any future changes to such guidelines and legislation. New information of improved practices and changes in legislation may require reinterpretation of the report as a whole, or in part.
1.6.6 This report does not constitute an archaeological or ecological assessment, nor does it constitute an asbestos inspection. A suitably qualified consultant should be consulted where these aspects of work are required.

2 SITE DETAILS AND DESCRIPTION
2.1 Introduction
2.1.1 Published environmental, geological and historical data relating to the site area has been reviewed, in conjunction with a walkover survey undertaken on Thursday 19th July 2018, the findings of which are presented below. The principal considerations of immediate relevance are presented in the following sections.
2.2 Site Location & Description
2.2.1 The site is located off Great Gutter Lane West, Willerby and is centred at approximate National Grid Reference (NGR) 501769mE, 430501mN. A site location plan is presented as Figure 41278/001. The site area is approximately 5.27 hectares (13.02 acres).
2.2.2 The site comprises an approximately rectangular parcel of land which is currently used as mixed residential and agricultural usage. At the time of the works, the site was divided into five separate parcels of land (Webb, Bradley, Swift, Robinson, and Murry).
2.2.3 The Webb parcel of land comprised an area of undeveloped agricultural land to the rear of their residential property. This land was accessed off Great Gutter Lane West, and up the driveway to the property. There were a small number of agricultural structures including a greenhouse and sheds. A mechanical lift was noted at the centre of this site. Apple and pear trees have been grown across the northern portion of the site. The eastern boundary is marked with a 2.5m tall wooden fence, the northern boundary is marked with hedgerows and fencing, with the southern boundary marked by trees and the western boundary was marked by a 1.5m tall fence.
2.2.4 The Bradley site was occupied with a two-storey detached residential property with soft landscaping garden areas to the front and rear of the property. This parcel of land was accessed from Great Gutter Lane West, up the driveway. The boundaries of this property were marked by a series of conifer hedgerows.
2.2.5 The Swift parcel of land comprised an undeveloped agricultural land to the south of the Bradley site and was accessed up a narrow track off Great Gutter Lane West. The southern, eastern and western boundaries of this site were marked by a number of mature trees.

2.2.6 The Robinson parcel of land was accessed off Great Gutter Lane, predominantly comprising an undeveloped parcel of agricultural land. Outbuildings noted during the intrusive works included a horse stable building at the centre of the parcel of land, with a storage shed at the southern portion of the site. A two-storey residential property with associated soft landscaping occupied the northern portion of the site adjacent to Great Gutter Lane. General building materials were noted within the southern portion of the site on an area of concrete hardstanding. The northern, southern and western boundaries were marked by several mature trees. The eastern boundary was marked by a 1.5m tall wire fence with barbed wire running along the top.
2.2.7 The Murray site comprised an undeveloped parcel of land, which has recently undergone a tree clearance programme and was capped with a layer of wood chippings. This site was accessed from the Robinson site. This parcel of land is located to the south of an existing commercial nursery business.

3 GEO-ENVIRONMENTAL SETTING
3.1 Anticipated Geology, Hydrogeology & Mining
3.1.1 A summary of the available published geological and hydrogeological information is provided in Table 3.1 below and overleaf. A review of the following information was undertaken:
British Geological Survey 1:50,000 scale series, 80 (Hull), Solid & Drift Edition; British Geological Survey on-shore borehole records database; Coal Authority database on coal mining reporting areas from the following web pages: - http://coal.decc.gov.uk/en/coal/cms/publications/data/map; - http://coal.decc.gov.uk/en/coal/cms/services/planning/strategy; Environment Agency online aquifer designation database; and Emapsite GeoInsight Data Report Ref. EMS-465690_625170 (Appendix A) and EnviroInsight Report Ref. EMS-465690_625171 (Appendix B), dated 5th March 2018.
Table 3.1 - General Geological Information Made Ground Deposits of made ground are not recorded within the site boundary. As the site has undergone limited phases of development, significant deposits of made ground are not anticipated. Superficial and Solid Superficial deposits are recorded as Devensian Till. Bedrock is Geology recorded as the Burnham Chalk Formation. Discontinuities There are no records of linear features within 500m of the site boundary. Hydrogeology With respect to site specific information presented on the Environment Agency’s website and Groundsure report, the following has been identified:
Superficial Deposits: ‘Secondary (A)’ Aquifer
‘Secondary A’ Aquifers comprise deposits that are capable of supporting water supplies at a local rather than strategic scale.
Bedrock: ‘Principal’ Aquifer
‘Principal’ Aquifers are layers of rock or drift deposits that are capable of supporting water supply and/or river base flow on a strategic scale.
Source Protection: The site is located within a ‘Zone 1’ and ‘Zone 2’ Source Protection Zone.
Vulnerability & Leaching Potential: The site is classified as a ‘Major Aquifer’ with ‘High to Intermediate Leaching Potential’. This classification reflects on urban areas with highly permeable soils. However, as the site is surfaced with a cohesive deposit, risk to the underlying ‘Secondary A’ and ‘Principal’ Aquifers is considered to be low. Hydrology There are no surface water features within 250m of the site boundary. Radon and Hazardous The site is not in a Radon Affected Area as less than 1% of Ground Gas (CH4 and properties are above the Action Level. No radon protective CO2) measures are required for the proposed new development. Report Prepared for Beal Developments Ltd and HSBC Bank Plc 13
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Coal Mining The site is not in a Coal Authority ‘Coal Mining Reporting Area’, or ‘Development High Risk Area’. Risk associated with coal mining is therefore considered to be negligible. Non-coal Mining There are no ‘Non-Coal’ mining cavities recorded within 1km of the study area. Natural Cavities There are no recorded natural cavities within 1km of the study area.
Table 3.2 - Environmental Data Discharge There are no records of ‘Red List’ discharge consents within 500m Consents of the site. Pollution Incidents There are no pollution incidents to controlled waters within 500m of to Controlled the study area.

4 HISTORICAL LAND USE
4.1.1 A study of historical Ordnance Survey maps has been undertaken to identify any potentially contaminative former land-uses at the site. The main historical features of the site and surrounding area are summarised in the following table, whilst a copy of the historical maps is presented in Appendix C.

4.1.7 The earliest available Ordnance Survey historical maps, dated c.1855 show the site to have been situated in an area of undeveloped agricultural land. The site was developed as residential properties c. 1961. Anecdotal evidence indicates that the site has historically been used as pastoral farm land. The adjacent land surrounding the site has been predominantly developed as residential properties. A shopping park was constructed to the north of the site (250m) c. 1994.

5 PHASE I GEOTECHNICAL APPRAISAL
5.1 Made Ground
5.1.1 Deposits of made ground are not recorded within the site boundary. As the site has undergone limited phases of development, significant deposits of made ground are not anticipated.
5.1.2 The presence, type and extent of any made ground soils will need to be established through ground investigation.
5.2 Natural Strata
5.2.1 The near surface superficial deposits are recorded as Devensian Till. These deposits generally comprise a cohesive deposit with sand and gravel in varying portions.
5.2.2 These soils are anticipated to largely comprise the Burnham Chalk Formation
5.3 Groundwater
5.3.1 No significant perched groundwater is anticipated.
5.3.2 True groundwater will be present within the underlying Burnham Chalk Formation bedrock at depth.
5.4 Stability Issues
5.4.1 The site slopes down towards Great Gutter Lane to the north and is consistent with the topography of the surrounding land. The proposed development is to comprise the construction of a number of residential properties. It is anticipated that re-grading of the site will be carried out as part of these development works. Where retaining structures are proposed, these should be designed to current standards.
5.4.2 Where excavations are proposed close to site boundaries, and properties a risk assessment of the integrity/stability should be undertaken prior to such works being carried out. Designed and engineered temporary/permanent measures should be adopted to ensure their continued stability.
5.4.3 With respect to natural ground subsidence, the site has been classified as having a 'Negligible' risk rating for compressible deposits and a 'Very Low' risk rating for
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 17
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
landslides, collapsible deposits, ground dissolution hazards, running sand hazards and shrink/swell clay.
5.4.4 Made ground deposits, where present, are anticipated to be unstable. Stability issues should also be anticipated within any near surface natural deposits, particularly where these are soft or weak or have been exposed to periods of heavy rainfall.
5.5 Coal Mining Induced Subsidence
5.5.1 As the site is not located within a Coal Authority ‘Coal Mining Reporting Area’, or ‘Development High Risk Area’, risk associated with coal mining related subsidence is considered to be negligible. Remedial works associated with coal mining activities is therefore considered to be negligible.
5.6 Non-Coal Mining and Quarrying
5.6.1 There are no records of ‘Non-Coal’ mining activities or natural cavities within 1km of the site.
5.6.2 However, a chalk pit was located between 450m and 800m to the north of the site, and Parson Pit has been excavated off the south-eastern site boundary (<50m).
5.6.3 Should evidence of quarrying be encountered on site during redevelopment this should be brought to the attention of Alan Wood and Partners. Where this is found to affect construction, appropriate precautions may need to be incorporated into the design (e.g. deepened foundations, reinforced superstructure etc). Such risk is considered, at this stage, to be low however.
5.7 Excavation Conditions
5.7.1 As chalk quarrying activities have taken place locally, the Burnham Chalk Formation bedrock deposit is anticipated at shallow depth. The excavation of the chalk bedrock should be achieved using conventional hydraulic excavation techniques.
5.7.2 It is likely that excavations should be relatively stable in the short term. However, some materials such as granular soils and made ground are liable to collapse without warning. This situation is likely to be exacerbated by water ingress. No man entry into unsupported excavations should be allowed without an appropriate risk assessment.
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 18
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Reference to CIRIA report 97 (1983) should be made to establish suitable means of support, or battering of excavation sides.
5.7.3 It is considered unlikely that dewatering will be required for shallow short-term excavations. Anticipated groundwater conditions suggest that simple dewatering techniques (e.g. sump pumping) are likely to be adequate to control water ingress on a routine basis. However, it is recommended that provision for the drainage of surface water is allowed for to prevent surface water ponding or collection both during and post construction, as this may lead to deterioration of the founding stratum.

6 PHASE I ENVIRONMENTAL ASSSESSMENT
6.1 Introduction
6.1.1 The following section summaries the Preliminary Phase I Conceptual Site Model (CSM), which has been produced following the review of available pertinent desk study and third-party information. The CSM summarises the understanding of surface and sub-surface features, the potential sources of contamination, pathways and receptors in order to support the identification and assessment of plausible contaminant linkages.
6.2 Initial Conceptual Site Model & Risk Assessment
6.2.1 The risk assessment has been carried out to assess the likelihood of risk to human health and the wider environment, on the basis of information reviewed. The risk assessment is a qualitative source-pathway-receptor assessment and its function is to assess the likelihood that each possible linkage exists and to decide whether they pose potentially unacceptable risks to identified receptors (i.e. people, structures, water bodies or ecosystems) that may be harmed.
6.2.2 Risk can be defined as the combination of the consequence of a harmful effect and the probability of its occurrence. The existence of a contaminant linkage is dependent on site use, as well as environmental conditions: if no contaminant linkage(s) can be proven, then the risk(s) may be discounted.
6.3 Site Summary & Environmental Sensitivity
6.3.1 A review of available desk study information indicates that the proposed development area and the adjacent land initially comprised an area of agricultural land, and has more recently been developed with residential properties. The adjacent land currently comprises areas of residential and agricultural usage.
6.3.2 Historic chalk quarrying works have been recorded between 450m and 800m to the north of the site and less than 50m to the south east of the site boundary. Chalk quarrying has not been recorded within the site boundary.
6.3.3 Deposits of made ground are anticipated to be limited due to the limited historical phases of development. However, the presence of chalk quarry pits will need to be confirmed through the completion of ground investigation works.
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 20
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
6.3.4 The underlying geology superficial deposits comprise Devensian Till. Bedrock is recorded as the Burnham Chalk Formation. Localised perched groundwater may be encountered, however, this is anticipated to be limited in extent.
6.3.5 A chalk quarry, Parsons Pit, has been recorded <50m to the South East of the site. This feature may have been infilled in the past with materials of unknown origin. There is also the potential for decaying organic matter to be present within the near surface superficial deposits. It is therefore considered possible that elevated concentrations of
hazardous ground gases CO2 and CH4 may be present. On this basis, it would be prudent to assess the potential for fugitive ground gas migration through a period of monitoring appropriate to the site's proposed residential end use.
6.3.6 Although the likely sources of significant contamination are expected to be limited, there remains the potential for on-site soils to contain naturally elevated concentrations of metals and metalloids (e.g. arsenic), non-metal inorganics and organic contamination (e.g. PAH). Limited and isolated hydrocarbon contamination, associated with areas of car parking and car repair areas should be assessed through laboratory analysis.
6.3.7 Although on site structures may have been constructed with the use of asbestos containing materials, due to the limited phases of development that have taken place at the site, asbestos is not anticipated in significant volumes within the near surface topsoil/made ground deposits. This should be confirmed through laboratory analysis.
6.3.8 The potential leaching of mobile contaminants of concern to the underlying Devensian Till (‘Secondary A’ Aquifer) and Burnham Chalk Formation (‘Principal’ Aquifer) is considered to be low, given the anticipated cohesive soil at the surface and limited phases of previous development that has occurred across the site, although a high to intermediate leaching potential of soils within the vicinity to the site is indicated.
6.3.9 In summary, given the site history, the anticipated contaminant load within the on-site soils, its underlying geology, gassing potential and the nature of controlled waters receptors, sensitivity of the site is considered, at this stage, to be low. The nature and concentration of any contamination will need to be confirmed through testing.

6.4 Potential Sources
6.4.1 A potential source is defined as ‘a contaminant which is in, or under the land and has the potential to cause harm to human health or to cause pollution of controlled waters’.
6.4.2 The following potential contaminants that may be associated with the site are summarised in Table 6.1.
Table 6.1 - Summary of Potential Contaminant Sources Associated Potential Contaminants (not limited to) Potential Sources Metals, inorganics and Organics other contaminants Contaminated made ground Heavy metals/metalloids, soils originating from PAH, TPH (inc BTEX) sulphate previous development Naturally occurring elevated levels of potential Heavy metals/metalloids, contaminants within the PAH sulphate underlying near surface natural strata Hazardous ground gases CH4 and CO2 (CH4 and CO2)
6.5 Summary of Potential Receptors
6.5.1 A receptor is the potential target of the source contaminant, to which either significant harm or deterioration in quality may be caused.
6.5.2 The potential sensitive receptors with respect to the potential contamination hazards identified above are considered below.

6.6 Plausible Pathways
6.6.1 Migration pathways are routes by which contaminant sources may come into contact with receptors. Potential pathways for different types of contaminants vary depending on the properties of the contaminant, the mechanism of its release and the nature of the receptor. The principal potential pollution pathways by which receptors might become exposed to potential contamination at the site are summarised as follows in Table 6.3 below.
Table 6.3 - Summary of Plausible Pathways
Potential Source Pathway
Direct ingestion, dermal contact, dust, and/or vapour inhalation Potentially contaminated Direct ingestion and/or dermal contact with liquid contaminants made ground soils, underlying natural strata / Leaching and direct contact with foundations and potable perched groundwater water supply pipes. Lateral migration of contaminants through preferential pathways Migration of gases and/or accumulation in void spaces via Ground gases transport through service conduit, any permeable made ground and/or underlying permeable strata
6.7 Risk Assessment
6.7.1 The potential contaminant linkages listed above are based on available data and the features noted during the ‘walkover’. Therefore, the linkages identified are tentative in nature and are subject to the following uncertainties (to be followed up through ground investigation):
Nature and extent of the made ground at the site;
Nature of the underlying natural strata at the site;
The actual distribution of contaminants within the made ground and underlying natural soils; The hydrogeological regime beneath the site.
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 23
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
6.7.2 The assessment presented herein assumes that the site end-use is to be residential, (with plant uptake). The assessment is not valid for other land uses. Should the proposed end-use of the site change, the assessment contained herein would need to be revised to accommodate this.
6.7.3 The identified potential contaminants and receptors have been considered in relation to the pathways that may link them. The risk classification has been estimated in accordance with those methods prescribed in CIRIA publication C552 ‘Contaminated Land Risk Assessment: A Guide to Good Practice’, 2001.
6.7.4 Risk is regarded as a combination of the likelihood of an ‘event’ occurring and its severity: both elements must be taken into account when assessing risk. The method for risk assessment, or evaluation, is purely qualitative. As defined in CIRIA C552:2001, the magnitude of the potential ‘severity’ of risk occurring may be assessed against:
Severe: short term risk to human health likely to result in significant harm as defined under EPA 1990, Part 2A. Short term risk of pollution to sensitive water receptor; Medium: significant harm to human health, pollution of sensitive water resource or significant change to an ecosystem or specific organism; Mild: pollution of non-sensitive water resource but significant damage to crops, buildings, structures and services or the environment; Minor: harm, which may result in financial loss, or expenditure to resolve. Non- permanent effects to human health. Easily repairable effects of damage to buildings, structures and services.
6.7.5 Similarly, the classification of the magnitude of the ‘probability’ of the risk occurring may be assessed against:
High Likelihood: a contaminant linkage exists and an event appears very likely in the short term, or almost inevitable in the long term, or pollution is causing harm at the receptor; Likely: a contaminant linkage exists and it is probable that an event will occur. An event may not occur, but it is possible in the short term and likely over the long term; Low Likelihood: a contaminant linkage exists and it is possible that an event will occur. It is not certain that an event will occur over time but it is less likely in the short
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 24
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
term; Unlikely: a contaminant linkage exists but it is not possible to say if an event will occur even over a very long time.
6.7.6 Following completion of the severity and probability assessment, classifications can be compared to indicate the actual risk each contaminant linkage presents: this can only be undertaken where there is a possibility of there being an active contaminant linkage.
6.7.7 The risk categories which can be assigned are presented in Table 6.4 below and range between ‘very high risk’ to ‘very low risk’; NB - it is not possible to classify an identified risk as ‘no-risk’.
Table 6.4 - Risk Categories Consequence
Severe Medium Mild Minor
Highly Very High High Moderate Moderate / Likely Low
Likely High Moderate Moderate / Low Low
Low Moderate Moderate / Low Very Low Likelihood Low Probability
Unlikely Moderate / Low Very Low Very Low Low
Reproduced from Table 6.5, CIRIA C552/2001.
Very High – severe harm could arise to a designated receptor or that severe harm is occurring. Urgent investigation and remediation is likely to be required; High – harm could occur to a designated receptor and that urgent investigation and remediation may be needed in the short term, but are likely over the longer term; Moderate – harm could occur. It is unlikely to be severe, most probably relatively mild. Investigation is normally required to clarify the risk with some remedial works being required in the longer term; Low – possible that harm could occur, but if it did, at worst it would be mild; Very Low – low possibility of harm arising, and that if it does it is not likely to be severe.

7 GROUND INVESTIGATION FIELDWORK
7.1 Introduction
7.1.1 The investigation requirements at the site were twofold: to undertake a geotechnical investigation and an environmental investigation. A site-wide ground investigation was therefore carried out to identify geotechnical and environmental liabilities in relation to the proposed development work at the site.
7.1.2 The positions of the exploratory locations are limited to areas of the site, within the site boundary, that were accessible during the works.
7.1.3 Alan Wood and Partners scoped the intrusive investigation on the basis of information submitted in the desk study report and in general accordance with guidance given in BS5930:1999+A2:2010, BS10175:2011+A1:2013 and BS EN 1997:2004 and 2007.
7.2 Site Works
7.2.1 The findings and recommendations given in this report are based on fieldwork undertaken between Thursday 19th July and Tuesday 24th July 2018. This work comprised the completion of 27 no. mechanically excavated trial holes and 12 no. windowless sample boreholes. The positions of the exploratory holes are shown on the appended ground investigation plan, Figure 41278/002. The investigation locations were positioned on the basis of the findings of the site conceptual model and distributed in general accordance with the requirements of BS10175:2011+A1:2013 and the working site conditions at the time each phase of investigation was completed.
7.2.2 The car parking at the Allandale Nurseries and car repair facility were targeted for potential hydrocarbon contaminants. Made ground soils adjacent to an external storage area was targeted for inorganic and organic (PAH) contaminants. No other specific areas of interest were targeted from an environmental point of view. Selected samples of the near surface cohesive superficial deposits were targeted for geotechnical laboratory analysis.

7.3 Geotechnical Investigation
7.3.1 The scope of works undertaken is outlined in Table 7.1 overleaf.
Table 7.1 - Summary of Works Maximum Recorded Depth Method of Investigation No. (m bgl) Machine excavated trial pits 27 3.30
Windowless sample boreholes 12 5.00
*Boreholes BH1, BH2, BH5, BH6, BH7, BH8, BH10, and BH12 were installed for ground gas monitoring.
7.3.2 A development-wide geotechnical investigation was carried out to identify liabilities in relation to the proposed construction works at the site and aid the design of appropriate foundation solutions. The following objectives of the ground investigation were therefore to:
Confirm the lateral and vertical extent of any made ground soils, the nature of the underlying natural ground and the depth to bedrock at selected positions across the area under investigation; Determine the depth to groundwater and the stability of excavation; Recover bulk samples for geotechnical testing where necessary; Undertake in situ hand shear vane testing (in cohesive soils in trial holes) where encountered and this test could be undertaken (i.e. within soils that were not friable or gravelly) and in situ Standard Penetration Testing (SPT) in the boreholes to determine soil strength and that of the underlying bedrock.
7.3.3 Standard strata descriptions of the soils encountered are in general compliance with BS EN 1997:2004, BS EN 1997:2007, BS EN ISO 14688:2002, BS EN ISO 14688:2004 and BS EN ISO 14689:2003. The individual strata depths recorded on each hand pit or borehole log are those from existing ground levels.
7.3.4 Geotechnical laboratory testing was undertaken on a selection of soil samples in accordance with those techniques outlined in BS 1377:1990 'Methods of Test for Soils for Civil Engineering Purposes' at the laboratory of Professional Soils Laboratory in Doncaster. This laboratory is a fully UKAS compliant laboratory.

7.4 Environmental Investigation
7.4.1 The environmental investigation was designed so that site-specific data could be obtained with respect to any potential soil and groundwater contamination associated with the site so that risks could be quantified in relation to the source-pathway-receptor scenarios and plausible contaminant linkages postulated in the initial Conceptual Site Model summarised above.
7.4.2 Given the potentially historic contaminative nature of the on-site soils, it was considered possible that, when considered within the context of proposed end-use, the on-site soils may present an (albeit low) unacceptable risk to human health and/or the wider environment.
7.4.3 The scope of works undertaken, were therefore to:
Inspect and identify the general soil conditions that prevail across the site; Assess the potential for soil contamination within any made ground, the underlying natural strata or groundwater; Recover soil samples to test for heavy metals, metalloids, non-metal inorganics, organics and asbestos fibres; and Install ground gas and ground water monitoring instrumentation to allow for the assessment of risk from fugitive ground gases.
7.4.4 Representative samples of the on-site soils were therefore recovered from the trial pits that were positioned to provide coverage of the site area under investigation. Sampling was undertaken in accordance with those guidelines prescribed in BS 10175:2011. All environmental samples were collected in 500ml plastic tubs with sealable lids, 250ml glass amber jars or vials (subject to analytical requirements). Care was taken to minimise cross contamination (i.e. wiping of equipment) between sampling. Environmental samples were packed into cool boxes with ice packs and transported by courier to Terratec, an MCERTS and UKAS accredited laboratory for analysis and subsequent storage.
7.4.5 The analytical strategy adopted for the environmental investigation was designed to provide an overall assessment of potential contaminants thought to likely be present within the on-site soils. Whilst no specific contaminants of concern were anticipated in

significant concentrations, the soil testing undertaken was for a suite of contaminants in general accordance with NHBC Standards Chapter 4.1 ‘Land Quality – Managing Ground Conditions’ and CLR 8 ‘Potential Contaminants for the Assessment of Land’ (withdrawn but used for reference purposes where applicable). The testing of the following analytes was scheduled on selected samples:
Heavy metals suite (including As, Cd, Cr, Cu, Hg, Pb, Ni, Zn); Speciated Polycyclic Aromatic Hydrocarbons; Speciated Total Petroleum Hydrocarbons (TPHCWG); BTEX and MTBE; Cyanide (free and total) and Thiocyanate; Phenol (total); Sulphates (Total and Water Soluble); Asbestos fibres; Sulphide; and pH.
7.4.6 Ground gas monitoring installations were installed in all five wells. A programme of works is to be carried out between August 2018 and November 2018 with a total of 6 no. visits being undertaken in accordance with CIRIA C665:2007. The results of the gas monitoring are to be reported under separate cover.

8.1.3 Made Ground: Isolated and discontinuous thin deposits of made ground were encountered at four locations (BH1, BH2, BH4, BH6, BH12, TP06, and TP15). This material generally comprised deposits of gravelly sand, with concrete, brick and chalk granular inclusions. A deposit of re-worked superficial deposit with brick and chalk inclusions was encountered at the north-eastern site boundary.
8.1.4 Natural Strata: The near surface superficial deposits comprised a firm to very stiff, cohesive Devensian Till deposit with varying chalk granular material. Chalk bedrock was encountered at between 0.70m bgl (BH11) and 4.00m bgl (BH6).
8.1.5 In accordance with Table 6 of BS EN ISO 14688-2:2018 the consistency index (IC) of the underlying cohesive soils may be described as high.

8.1.6 Burnham Chalk: This was encountered below the cohesive glacial deposits within all of the windowless sampler boreholes and within trial pits TP4 to TP7 and TP11 to TP27. The base of the chalk was not encountered during this investigation. The upper part of the chalk was noted to be fully weathered to a gravely clay (Weathering Grade V) and to become gravelly and stronger with depth (Weathering Grade IV).
8.1.7 Groundwater: Perched groundwater was encountered at 1.60m in BH5.
8.2 Visual & Olfactory Evidence of Contamination
8.2.1 No visual or olfactory evidence of gross contamination, such as hydrocarbons, was recorded during the ground investigation.
8.3 Geotechnical Testing & Material Properties
Standard Penetration Testing
8.3.1 In situ standard penetration testing was undertaken in all five boreholes so that an assessment on material strength and an approximate safe bearing capacity of the ground could be ascertained.
8.3.2 The field test is useful for comparing variability of backfill materials as well as undisturbed natural soils to check for possible differential settlement problems. SPT tests were carried out at 1.0m centres throughout the vertical profile of each borehole.
8.3.3 A summary of the test results is given in the following tables, Table 8.2 overleaf.

Atterbergs, Moisture Content & Volume Change Potential
8.3.4 The geotechnical laboratory testing was carried out on six samples of cohesive soil by PSL LTD. A copy of the test results is presented in Appendix E but are summarised in Table 8.3.

8.3.5 The Plasticity Index (lp) of a soil is a measure of its Volume Change Potential (VCP) and is determined by Atterberg Limits tests, the results of which are given in the above
table. All tests to determine the liquid limit (wL) and plastic limit (wp) were also performed by PSL LTD. A Modified Plasticity Index (l'p) has been calculated for the samples tested, which is defined as the Plasticity Index multiplied by the percentage of particles less than 425µm. The conversion factor applied is presented in NHBC Standards (2003), Chapter 4.2.
8.3.6 The calculated modified plasticity index (NHBC Chapter 4.2) was found to be between 15% and 31%, which is equivalent to a low to medium volume change potential, according to the NHBC guidelines. The highest recorded worst-case VCP (medium) should be adopted for design purposes however to allow for variation in ground conditions across the development area.

8.3.8 Hand shear vane test results, recorded during the site investigation works produced a range of corrected undrained shear strengths ranged from 133N/m2 to 188kN/m2. The mean and median undrained shear strengths were calculated as 181kN/m2 and 188kN/m2 and are generally indicative of high strength soils in accordance with Table 6 of BS EN ISO 14688-2:2018.

Contamination and Performance of Building Materials (Cementitious Products)
8.3.9 Nine soil samples were analysed for a suite of contaminants consistent with BRE Special Digest 1 ‘Concrete in Aggressive Ground' (2005). A copy of the individual test results is given in the appended laboratory certificates in Appendix F.
8.3.10 The pH values recorded for the soil samples ranged between 5.1 and 8.1 (pH units) with an average of 6.9, indicating near neutral conditions prevail within the on-site soils.
8.3.11 Water soluble sulphate analysis of the soils yielded concentrations between <0.01g/l and 0.08g/l in the samples (0.02g/l on average). An assessment of the data was carried out in accordance with Section C4 'Site Investigation for Aggressive Ground Conditions' and the procedure prescribed in Section C5 'Classification of Site Locations for Chemicals Aggressive to Concrete' of BRE SD1 (2005) to assess whether ground conditions at the site are potentially aggressive to buried concrete products. The results of the assessment indicate that a Design Sulphate classification of DS-1 may be adopted along with an ACEC class of AC-1s. However, it is recommended that where made ground is encountered DS2 sulphate precautions should be adopted in foundation construction.
8.3.12 Static groundwater conditions have been assumed in this assessment.

9 LABORATORY CHEMICAL TESTING
9.1 Preamble
9.1.1 Nine representative samples of soil from within the near surface, to a maximum depth of 0.50m below ground level, were analysed for the suite of contaminants outlined in Section 7.4.5 above. This was in order to assess the general degree and nature of contamination within the on-site soils in relation to the site's proposed redevelopment.
9.1.2 Two soil leachate tests were also carried out to assess the potential for contaminant migration to controlled waters receptors.
9.1.3 A summary of the test results is given in the following tables, whilst a copy of the individual test results is presented in full in Appendix F.
9.2 Guidance for Analytical Results - Assessment Criteria
Soil
9.2.1 With reference to the proposed end use of the site, the results of the chemical testing were assessed as part of an environmental risk assessment against a number of potential receptors, considering risks to human health, environmental quality and the built environment. Such risk assessment comprises the initial comparison of the measured soil concentrations with Generic Assessment Criteria (GAC), which in this instance are considered protective of a residential end use.
9.2.2 Recent changes to UK human health risk assessment has seen the introduction of DEFRAs Category 4 Screening Levels (2014) and the LQM/CIEH Suitable 4 Use Levels (2015). Both set out to provide generic assessment criteria on the basis of updated assumptions relating to the modelling of human exposure to soil contaminants for the standard land uses: residential (with and without home-grown produce), allotments, commercial and public open space.
9.2.3 The general consensus between contaminated land practitioners is that the C4SL values, which are based on the low level of toxicological concern (LLTC), are less cautious than the newly revised GAC values published by LQM/CIEH and may not, therefore, be wholly applicable for use outside the context of Part 2A Statutory Guidance. Although both publications in no way undermine the validity of existing Environment Agency guidance presented in, for example, SR2, SR3 and the existing
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 38
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
CLEA software, we are of the mind that the LQM/CIEH S4UL values, which are based on Health Criteria that represents minimal or tolerable levels of risks to health (as described in the Environment Agency's SR2 guidance) but incorporates the updated exposure assumptions presented in DEFRAs C4SL guidance, provide a better starting point from which to generate generic assessment criteria that can be applied to brownfield development sites and are 'suitable for use' under the planning system.
9.2.4 It should be noted that both approaches are based on sandy loam soil with 6% soil organic matter (SOM). Whilst this does not present a problem for metals, as they are not dependent on soil type or SOM, the algorithms used to model plant uptake and volatilisation for organic contaminants do take account of SOM content in the soil. The GAC values for metals in the standard land uses may therefore be directly applied, whether these are C4SL or S4UL derived, whilst independent GAC values for organics (e.g. PAH, TPH) have been generated using CLEA Version 1.071 and the toxicological updates presented in the aforementioned documents. These have also been adjusted for soil type and are calculated for SOM contents at 1%, 2.5% and 6% for a sandy soil.
9.2.5 A summary of the generic assessment criteria values is presented in Appendix G.

Metals, Metalloids and Other Inorganic Analytes
9.3.2 A total of 9 no. soil samples were analysed. Assessment of the soils data indicates that there are elevated concentrations of lead that exceed relevant GAC criteria in one location on the site (TP15) within the made ground. Analysis of soil leachate samples returned no concentrations above relevant GAC's.
9.3.3 Potential unacceptable risk to human health in a residential with plant uptake land use scenario with respect to metals, metalloids and non-metal inorganics is therefore anticipated associated with the localised made ground encountered at TP15. Risk can mitigated by ensuring this material is not retained within 600mm of finished ground level beneath garden areas.
Organics (PAH, TPH, BTEX and MTBE)
9.3.4 A total of 9 no. soil samples and 2 no. leachate samples were analysed. Seven of the tests on soil samples and four of the tests on leachate samples analysed for PAH, TPH, BTEX or MTBE returned concentrations above relevant GAC's.
9.3.5 Increased level PAH concentrations were measured within samples of made ground recovered from trial holes TP06 and TP15, and borehole BH06.
9.3.6 Potential unacceptable risk to human health in a residential with plant uptake land use scenario with respect to organic contaminants is therefore anticipated associated localised made ground found in BH6 and TP15. Risk can be mitigated by ensuring this material is not retained within 600mm of finished ground level beneath garden areas.
Asbestos
9.3.7 A total of 9 no. soil samples were analysed. No asbestos fibres were detected in the samples tested.
9.3.8 Risk associated with asbestos containing materials is therefore not anticipated.
UKWIR
9.3.9 Note that the use of barrier pipe is applicable for all brownfield sites according to the UKWIR guidelines. It is recommended that consultation be held with the water authority to confirm any specific requirements they may have.

10 PHASE II ENVIRONMENTAL APPRAISAL
10.1 Introduction
10.1.1 The preliminary CSM given above presented our initial understanding of the site, being based on available geological information, site location, likely contamination status and the overall risk it presented to the identified receptors through various pollution pathways.
10.1.2 This section revises the initial CSM considering the ground investigation findings and chemical analysis results presented above.
10.1.3 The revised conceptual site model has been developed for the proposed future residential site end use, with plant update. This summarises our understanding of surface and sub-surface features, the potential contaminant sources, transport pathways and receptors assuming that no remediation has been undertaken at the site.
10.2 Ground Conditions - Summary
10.2.1 Made Ground: Isolated deposits of made ground were encountered at four locations (BH1, BH2, BH4, BH6, BH12, TP06, and TP15). This material generally comprised deposits of gravelly sand, with concrete, brick and chalk granular inclusions. A deposit of re-worked superficial deposit with brick and chalk inclusions were encountered at the north-eastern site boundary.
10.2.2 Natural Strata: The near surface superficial deposits comprised a firm to very stiff, cohesive Devensian Till deposit with varying chalk granular material. Chalk bedrock was encountered at between 0.70m bgl (BH11) and 4.00m bgl (BH6).
10.2.3 Perched groundwater was encountered at 1.60m at BH5.
10.2.4 Elevated contaminants were found in made ground samples, in both soil and leachate tests, taken from TP06, TP15, and BH06.
10.3 Qualitative Contaminated Land Risk Assessment
10.3.1 Current UK legislation on contaminated land is principally contained in Sections 78(A) to (YC) in Part 2A of the Environmental Protection Act 1990, which was retrospectively
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 44
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
inserted by Section 57 of the Environment Act 1995. The Contaminated Land Regulations 2000 were amended in 2005. The Environmental Protection Act 1990: Part 2A Contaminated Land, Statutory Guidance, Edition 2, 2006, promulgates the revised statutory guidance with respect to the operation of the Contaminated Land Regime following the implementation of the Contaminated Land Regulations, 2005.
10.3.2 The definition of contaminated land is central to the operation of Part 2A. Legislation adopts the principle of a 'suitable for use' approach for the assessment of contaminated land, the rationale reflected in the site-specific risk assessment and determination of remedial strategy. Action is only required if unacceptable risks are posed to human health or to the environment, taking into account the current land use and geo-environmental setting.
10.3.3 The legislation places a responsibility on the Local Authority to determine whether the land under its jurisdiction is contaminated by consideration of whether:
Significant harm is being caused; There is a significant possibility of significant harm being caused; Significant pollution of controlled waters is being caused or is likely to be caused.
10.4 Assessment Framework
10.4.1 The statutory guidance describes a risk assessment methodology in terms of ‘significant contaminants’ and ‘contaminant linkages’, using ‘source-pathway-receptor’ scenarios for the site. Contaminant linkages are formed when there is a linkage between a contaminant source and a receptor by means of a pathway. Each element has to be present, or no linkage can be formed.
10.4.2 Risk assessment and the procedure of identifying sources, pathways and receptors is recognised as an approach to determine the extent and significance of contamination either within the context of Part 2A (when assessing current site status or when considering the acquisition of an existing development) or the planning process (for the redevelopment of an existing site, or when considering the acquisition of a site for redevelopment purposes). Either way, the ‘suitable for use’ approach is adopted when assessing risk and the source-pathway-receptor assessment defines the conceptual model for the site.

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
10.4.3 Within the context of this report therefore, the revised risk assessment has been undertaken on the basis that the ‘suitable for use’ approach remains aligned with the site being redeveloped for the end use given above.
10.5 Summary of Identified Contaminant Linkages
10.5.1 On the basis of the ground investigation and laboratory test results, it is evident that the on-site soils contain elevated concentrations of inorganic and organic contaminants in excess of the adopted GACs.
10.5.2 Risk to human health, the development and the wider environment, with respect to the identified levels of contaminants within the on-site soils, is therefore anticipated. These risks can be mitigated by ensuring that the made ground material is not retained within 600mm of finished ground level.
10.5.3 Elevated leachable contaminants have been identified within isolated deposits of made ground. These deposits are isolated in extent, both vertically and laterally, are part of the unsaturated zone, and underlain by cohesive superficial deposits. It is likely that this material will be removed as part of the site re-development. As a result, the risk to controlled waters is considered to be very low. Subject to approval, this material could be re-used under areas of hardstanding, including driveways and roads.
10.5.4 A summary of the revised risk assessment is given in Table 10.1.

11 CONCLUSIONS AND RECOMMENDATIONS
11.1 General
11.1.1 This geo-environmental appraisal has been carried out in relation to the redevelopment of land off Great Gutter Lane, West.
11.1.2 It has been assumed in the production of this report that the site is to be redeveloped for a residential site end use, with plant uptake.
11.2 Soil Contamination - Risk Evaluation
11.2.1 The revised Conceptual Site Model confirms that potential contaminant linkages exist at the site in relation to existing on-site soils.
Human Health Receptors
11.2.2 Although elevated concentrations of potential contaminants of concern above relevant commercial GAC values were measured within the on-site soils, risk to future end users of the site is considered to be low. The made ground deposits within which elevated levels of contaminants have been found should be removed or capped. It may be that there is a short-term risk (acute) to construction workers from PAH contamination may exist where localised made ground soils are present within the south-eastern site corner.
11.2.3 Any potential risks to construction workers must be specifically assessed as part of the health and safety evaluation for the works to be performed in accordance with prevailing legislation. Site practices must conform to the specific legislative requirements and follow appropriate guidance (e.g. HSE, 1991; CIRIA, 1996).
Controlled Waters Receptors
11.2.4 Elevated leachable contaminants have been identified within isolated deposits of made ground. These deposits are isolated in extent, both vertically and laterally, are part of the unsaturated zone, and underlain by cohesive superficial deposits. It is likely that this material will be removed as part of the site re-development. As a result, the risk to controlled waters is considered to be very low. Subject to approval, this material could be re-used under areas of hardstanding, including driveways and roads.
Ecological Receptors

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
11.2.5 There are no ecological receptors at the site.
Utilities
11.2.6 It is recommended that the results of the chemical testing and details of the proposed redevelopment of the site are provided to the appropriate utility companies to determine the necessity for service protection.
11.2.7 Risk to potable water supply pipes is considered to be very low.
Potable Water Supplies
11.2.8 Elevated leachable contaminants have been identified within isolated deposits of made ground. These deposits are isolated in extent, both vertically and laterally, are part of the unsaturated zone, and underlain by cohesive superficial deposits. It is likely that this material will be removed as part of the proposed development work. Risk to potable water supply pipes is therefore considered to be low.
11.2.9 On the basis of available test results it is unlikely that protective measures will be required. Consultation should however be undertaken with the local water authority with respect to any precautions they may require, prior to construction. Ground Gas Risk
11.2.10 The potential for ground gas generation will be reported under separate cover once the requisite period of monitoring has been completed.
Asbestos Containing Materials
11.2.11 No asbestos fibres were identified in the samples near surface soils analysed by the laboratory. Risks to construction workers and site end users are considered to be low.

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Radon Precautions
11.2.12 The site is not in a Radon Affected Area as less than 1% of properties are above the Action Level. No radon protective measures are required for the proposed new development.
11.3 Construction - Risk Evaluation
Site Preparation
11.3.1 A significant part of the enabling works will comprise the removal/stripping and stockpiling of existing topsoil from beneath development areas. Topsoil was encountered up to 0.10m bgl. However, localised deeper parcels of topsoil may be encountered during the re-development of the site. It is anticipated that re-grading of site levels will be required in order to construct a suitable development platform.
11.3.2 It may be that these works will need to be undertaken to an approved earthworks specification.
Sulphate Attack
11.3.3 Soil sulphate concentrations measured during the investigations have been compared to levels within the BRE Special Paper SD1:2005. In considering the sulphate values, the site has been assessed as 'brownfield'.
11.3.4 The on-site soils are not considered to be at risk from containing pyrite.
11.3.5 Design Sulphate classification of DS-1 should be suitable along with an ACEC class of AC-1s. However, this does not make any necessary allowance for the requirements of structural strength, or requirements for durability of concrete. Further consultation should be made with the designing engineer with respect to the site-specific sulphate resistant concrete to be used.
11.3.6 Where made ground is encountered and is to remain on site, DS2 sulphate precautions may need to be adopted.

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Mining Risk
11.3.7 On the basis of the mining investigation, the potential for there to be shallow mine workings beneath the site is considered to be negligible.
Foundations
11.3.8 Made ground soils of any type are not suitable founding stratum.
11.3.9 It is considered, where competent undisturbed natural strata is encountered at founding depth that, for structures of typical construction, traditional deep strip, trench- fill or pad foundations should be suitable.
11.3.10 A minimum footing depth of between 0.90mm in this instance will probably be adequate when in cohesive soils and outside the zone of influence of trees (see below). It is recommended that a plot specific foundation schedule is completed for the site, with allowances for existing and proposed trees.
11.3.11 The widening, strengthening and reinforcement of foundations in accordance with NHBC Standards would be required where footings are found to straddle strata of different type (e.g. sand, clay, silt) or where soft and/or where locally unstable ground is encountered at founding depth.
11.3.12 Where ground disturbance is encountered during construction, for example where historic chalk pits are uncovered, an assessment of the ground and its implication on foundation design will need to be undertaken. In this instance it is envisaged that some ground improvement may be required with foundations being suitably strengthened/reinforced or an alternate foundation solution being implemented. This risk is likely to be low, but a watching brief should be undertaken during construction.
Floor Slabs
11.3.13 Ground bearing slabs could be used where ground conditions allow, and no precautionary measures associated with soft and unstable soils are required.
11.3.14 A suspended floor system incorporating a sub-floor void, such as beam and block, will be required for all structures where the foundations lie within the heave zone of trees as defined by NHBC Standards (Chapter 4.2), or where seasonally desiccated soils are present at the time of construction.
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 51
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
11.3.15 Where foundations do not lie within the heave zone of trees, a ground bearing floor slab is considered to be suitable. Where ground bearing slabs are implemented, care must be taken to ensure that shallow strata do not become heavily disturbed by site clearance/construction activities (especially during inclement weather). Where this occurs, this could result in an increased requirement for suspended floor slabs.
Precautions Near Trees
11.3.16 There are many trees around the boundaries to the site and locally within, so precautions are likely to be required where structures lie within influencing distance given the underlying (clay) ground conditions that prevail at the site; this will be subject to a tree survey and plot specific foundation schedule.
11.3.17 Identified trees have included; mature silver birch (low), maple leaf (moderate), conifer, oak (high) and pine trees (moderate). These trees have a range of water demand levels ranging between low to high water demand.
11.3.18 The calculated plasticity index has been calculated at between 15% and 31%, which is equivalent to a low to medium volume change potential. However, the highest recorded VCP (medium) should be adopted for foundation design. Foundations can be reduced by 0.15m (150mm) due to allowances made for the climate at the site location.
11.3.19 The minimum foundation depth within the influence of trees with a moderate VCP and moderate or water demand is 0.90m (0.75m) bgl, and 1.00m (0.85m), respectively.
11.3.20 In addition, precautions would be required where trees are to be removed or where new planting is proposed. All foundations should be constructed in accordance with NHBC Standards (i.e. Chapter 4.2).
Drainage and Soakaways
11.3.21 The cohesive superficial deposits are not suitable for soakaway drainage. Based on observations made during a preliminary soakaway drainage test, completed on 12th April 2018, the Burnham Chalk Formation is not considered to be suitable for soakaway drainage for the site. Therefore, surface water will need to be discharged into the local system, subject to obtaining the necessary consents and approvals.

Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
Roads and Car Parks
11.3.22 No in situ CBR testing has been carried out to date as the final development levels at the site are unknown.
11.3.23 On the basis of visual observation, it is considered that the near surface soils are likely to have a minimum CBR value of around 3.0%, perhaps higher, but this should be confirmed.
11.3.24 Highways Agency document HD25 Interim Advice Note 73/06 Revision 1 (2009) states that where a subgrade has a CBR lower than 2.5%, it is considered unsuitable support for a pavement foundation since it would tend to deform under construction traffic and must be improved. All road design should be discussed with the local authority if highways are to be subject to a Section 38 agreement.
Ground Stability
11.3.25 No significant ground instability is anticipated, although some should be anticipated within the near surface if granular or weak strata are present, or where excavations are left open during prolonged periods of wet weather (e.g. in service trenches). The underlying horizons of sand, where encountered at depth, were also observed to be unstable once exposed. This situation is likely to be exacerbated by water ingress. Allowance for instability in this material should be made where necessary.
11.3.26 An adequate drainage system for surface water may need to be installed by a competent contractor in order to prevent surface water ponding or collection, both during and post construction, as this may lead to deterioration and weakening of the founding stratum.
11.3.27 Where excavations are proposed close to site boundaries and there is the possibility of weak/unstable ground passing across that boundary and beneath adjacent structures, a risk assessment of the integrity/stability should be undertaken prior to such works being carried out. Designed and engineered temporary/permanent measures should be adopted to ensure their continued stability where necessary.
Excavations
Report Prepared for Beal Developments Ltd and HSBC Bank Plc 53
Phase I/II Geo-Environmental Assessment Report Address: Willerby ‘Phase II’, Great Gutter Lane, Willerby, Hull Project Number: - JS/ST/41278-Rp001
11.3.28 Localised obstructions to excavations or shallow hard rock are not anticipated given the geology and lack of previous development.
11.3.29 Should remnant foundations or road base construction be encountered, in addition to that proven in the south-eastern corner, the peckering-out of obstructions for either foundations or other construction requirements should be allowed for. Excavation of the materials encountered should be easily achieved using conventional hydraulic excavation techniques.
11.3.30 No man entry into unsupported excavations should be allowed without an appropriate risk assessment. Reference to CIRIA report 97 (1983) should be made to establish suitable means of support, or battering of excavation sides.
Outline Remediation Requirements
11.3.31 Where localised areas of made ground remains within 500mm of the finished ground surface and within gardens areas, this will need to be capped by a designed and engineered barrier system comprising of at least 450mm of suitably clean subsoil and 150mm of topsoil. The barrier system can be reduced to a minimum of 450mm within below public soft landscaped areas. Suitable made ground materials can be transposed to below proposed access roads and paved areas subject to approval by the Planners and Regulators.
11.3.32 Confirmation of the chemical condition of any materials brought to site should be confirmed prior to importation.
11.3.33 Should brightly coloured or odorous soil be encountered during the proposed construction works, Alan Wood and Partners should be notified immediately. An experienced geo-environmental engineer will visit site for further sampling, analysis and risk assessment, where required.
11.3.34 A watching brief should be undertaken during the demolition works of existing buildings in order to highlight any previously unidentified sources of contamination.

Is the property in a Radon Affected Area as defined by the Health Protection Agency (HPA) and if so what percentage of homes are above the Action Level? The property is not in a Radon Affected Area, as less than 1% of properties are above the Action Level.
The radon data in this report is supplied by the BGS/Public Health England and is the definitive map of Radon Affected Areas in Great Britain and Northern Ireland. The dataset was created using long-term radon measurements in over 479,000 homes across Great Britain and 23,000 homes across Northern Ireland, combined with geological data. The dataset is considered accurate to 50m to allow for the margin of error in geological lines, and the findings of this report supercede any answer given in the less accurate Indicative Atlas of Radon in Great Britain, which simplifies the data to give the highest risk within any given 1km grid square. As such, the radon atlas is considered indicative, whereas the data given in this report is considered definitive.
3.2 Radon Protection
Is the property in an area where Radon Protection are required for new properties or extensions to existing ones as described in publication BR211 by the Building Research Establishment? No radon protective measures are necessary.

Contacts This section of the report provides contact points for statutory bodies and data providers that may be able to provide further information on issues raised within this report. Alternatively, Groundsure provide a free Technical Helpline (08444 159000) for further information and guidance. Note: Maps Only certain features are placed on the maps within the report. All features represented on maps found within this search are given an identification number. This number identifies the feature on the mapping and correlates it to the additional information provided below. This identification number precedes all other information and takes the following format -Id: 1, Id: 2, etc. Where numerous features on the same map are in such close proximity that the numbers would obscure each other a letter identifier is used instead to represent the features. (e.g. Three features which overlap may be given the identifier “A” on the map and would be identified separately as features 1A, 3A, 10A on the data tables provided). Where a feature is reported in the data tables to a distance greater than the map area, it is noted in the data table as “Not Shown”. All distances given in this report are in Metres (m). Directions are given as compass headings such as N: North, E: East, NE: North East from the nearest point of the study site boundary.

Are there any Source Protection Zones within the Confined Aquifer within 500m of the study site? No
Historically, Source Protection Zone maps have been focused on regulation of activities which occur at or near the ground surface, such as prevention of point source pollution and bacterial contamination of water supplies. Sources in confined aquifers were often considered to be protected from these surface pressures due to the presence of a low permeability confining layer (e.g. glacial till, clay). The increased interest in subsurface activities such as onshore oil and gas exploration, ground source heating and cooling requires protection zones for confined sources to be marked on SPZ maps where this has not already been done.

7.2 River and Coastal Zone 3 Flooding
Is the site within 250m of an Environment Agency/Natural Resources Wales Zone 3 floodplain? No
Zone 3 shows the extent of a river flood with a 1 in 100 (1%) or greater chance of occurring in any year or a sea flood with a 1 in 200 (0.5%) or greater chance of occurring in any year. Any relevant data is represented on Map 7a – Flood Map for Planning.
Database searched and no data found.
7.3 Risk of Flooding from Rivers and the Sea (RoFRaS) Flood Rating
What is the highest risk of flooding onsite? Very Low
The Environment Agency/Natural Resources Wales RoFRaS database provides an indication of river and coastal flood risk at a national level on a 50m grid with the flood rating at the centre of the grid calculated and given above. The data considers the probability that the flood defences will overtop or breach by considering their location, type, condition and standard of protection.
RoFRaS data for the study site indicates the property is in an area with a Very Low (less than 1 in 1000) chance of flooding in any given year.
Any relevant data within 250m is represented on the RoFRaS Flood map. Data to 50m is reported in the table below.

7.6 Areas benefiting from Flood Storage
Are there any areas used for Flood Storage within 250m of the study site? No
7.7 Groundwater Flooding Susceptibility Areas
7.7.1 Are there any British Geological Survey groundwater flooding susceptibility areas within 50m of the boundary of the study site? Yes
Does this relate to Clearwater Flooding or Superficial Deposits Flooding? Clearwater Flooding
Notes: Groundwater flooding may either be associated with shallow unconsolidated sedimentary aquifers which overlie unproductive aquifers (Superficial Deposits Flooding), or with unconfined aquifers (Clearwater Flooding).
7.7.2 What is the highest susceptibility to groundwater flooding in the search area based on the underlying geological conditions?
Limited potential Where limited potential for groundwater flooding to occur is indicated, this means that although given the geological conditions there may be a groundwater flooding hazard, unless other relevant information, e.g. records of previous flooding, suggests groundwater flooding has occurred before in this area, you need take no further action in relation to groundwater flooding hazard.
7.8 Groundwater Flooding Confidence Areas
What is the British Geological Survey confidence rating in this result? High
Notes: Groundwater flooding is defined as the emergence of groundwater at the ground surface or the rising of groundwater into man-made ground under conditions where the normal range of groundwater levels is exceeded.
The confidence rating is on a threefold scale - Low, Moderate and High. This provides a relative indication of the BGS confidence in the accuracy of the susceptibility result for groundwater flooding. This is based on the amount and precision of the information used in the assessment. In areas with a relatively lower level of confidence the susceptibility result should be treated with more caution. In other areas with higher levels of confidence the susceptibility result can be used with more confidence.

9.1 Detailed BGS GeoSure Data
BGS GeoSure Data has been searched to 50m. The data is included in tabular format. If you require further information on geology and ground stability, please obtain a Groundsure Geo Insight, available from our website. The following information has been found:
9.1.1 Shrink Swell
What is the maximum Shrink-Swell** hazard rating identified on the study site? Very Low
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard Ground conditions predominantly low plasticity. No special actions required to avoid problems due to shrink-swell clays. No special ground investigation required, and increased construction costs or increased financial risks are unlikely due to potential problems with shrink-swell clays.
9.1.2 Landslides
What is the maximum Landslide* hazard rating identified on the study site? Very Low
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard Slope instability problems are unlikely to be present. No special actions required to avoid problems due to landslides. No special ground investigation required, and increased construction costs or increased financial risks are unlikely due to potential problems with landslides.
9.1.3 Soluble Rocks
What is the maximum Soluble Rocks* hazard rating identified on the study site? Very Low
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard Significant soluble rocks are present. Problems unlikely except with considerable surface or subsurface water flow. No special actions required to avoid problems due to soluble rocks. No special ground investigation required or increased construction costs are likely. An increase in financial risk due to potential problems with soluble rocks is unlikely.
* This indicates an automatically generated 50m buffer and site.
Report Reference: EMS-465690_625171 Client Reference: EMS_465690_625171 51 9.1.4 Compressible Ground
What is the maximum Compressible Ground* hazard rating identified on the study site? Negligible
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard No indicators for compressible deposits identified. No special actions required to avoid problems due to compressible deposits. No special ground investigation required, and increased construction costs or increased financial risks are unlikely due to potential problems with compressible deposits.
9.1.5 Collapsible Rocks
What is the maximum Collapsible Rocks* hazard rating identified on the study site? Very Low
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard Deposits with potential to collapse when loaded and saturated are unlikely to be present. No special ground investigation required or increased construction costs or increased financial risk due to potential problems with collapsible deposits.
9.1.6 Running Sand
What is the maximum Running Sand** hazard rating identified on the study site? Very Low
The following natural subsidence information provided by the British Geological Survey is not represented on mapping:
Hazard Very low potential for running sand problems if water table rises or if sandy strata are exposed to water. No special actions required, to avoid problems due to running sand. No special ground investigation required, and increased construction costs or increased financial risks are unlikely due to potential problems with running sand.
* This indicates an automatically generated 50m buffer and site.
Report Reference: EMS-465690_625171 Client Reference: EMS_465690_625171 52 9.2 Radon
9.2.1 Radon Affected Areas
Is the property in a Radon Affected Area as defined by the Health Protection Agency (HPA) and if so what percentage of homes are above the Action Level? The property is not in a Radon Affected Area, as less than 1% of properties are above the Action Level.
The radon data in this report is supplied by the BGS/Public Health England and is the definitive map of Radon Affected Areas in Great Britain and Northern Ireland. The dataset was created using long-term radon measurements in over 479,000 homes across Great Britain and 23,000 homes across Northern Ireland, combined with geological data. The dataset is considered accurate to 50m to allow for the margin of error in geological lines, and the findings of this report supercede any answer given in the less accurate Indicative Atlas of Radon in Great Britain, which simplifies the data to give the highest risk within any given 1km grid square. As such, the radon atlas is considered indicative, whereas the data given in this report is considered definitive.
9.2.2 Radon Protection
Is the property in an area where Radon Protection are required for new properties or extensions to existing ones as described in publication BR211 by the Building Research Establishment? No radon protective measures are necessary.
Report Reference: EMS-465690_625171 Client Reference: EMS_465690_625171 53 10. Mining
10.1 Coal Mining
Are there any coal mining areas within 75m of the study site? No
Database searched and no data found.
10.2 Non-Coal Mining
Are there any Non-Coal Mining areas within 50m of the study site boundary? No
Database searched and no data found.
10.3 Brine Affected Areas
Are there any brine affected areas within 75m of the study site? No Guidance: No Guidance Required.
