1 INTRODUCTION

1.1 Brief This report has been prepared to assesses potential impacts to land and water (geology, hydrogeology, hydrology & flood risk) associated with the proposed changes to the restoration scheme for Manor Farm, Longwater Road, Finchampstead (the Site). The existing planning consent for the Manor Farm (the Site) was approved by Wokingham Borough Council in December 2006 (VAR/2006/8160). This planning consent allows the extraction of sand and gravels and subsequent restoration of the Site to a series of lakes, ponds, reed beds and associated wetlands as shown in restoration plan P8/530/26/C dated November 2006. A copy of the existing restoration plan is provided in Appendix A. CEMEX UK Operations Ltd (the Operator) seek to modify the approved restoration scheme as indicated on the proposed restoration plan P8/530/26/F dated October 2012. A copy of the proposed revised restoration plan is provided in Appendix B. It is understood that the proposed amendment to the extant planning consent will be addressed by a simple planning application supported by relevant technical documents without a new or revised Environmental Statement. It is understood that Wokingham Borough Council have agreed that an Environmental Statement is not required to support the application for the proposed change. The Operator has indicated that the proposed chance can be addressed on the basis of a standard planning application supported by relevant technical information, such as this report. 1.2 Study Area The Site covers an area of 52.87 hectares, located upon land to the east of Longwater Road, Finchampstead, Hampshire, within the boundary of Wokingham Borough Council. The Site is bordered on its southern boundary by the River Blackwater and centred on an approximate National Grid Reference (NGR) of 479987, 162517. The Site forms part of the Eversley Quarry complex which includes two other operational quarry areas known as Chandlers Farm (immediately to the south of the Site and the River Blackwater) and Fleethill Farm (to the west of the Site and Longwater Road). The study area (the Site) is presented in Figure 2.1. 1.3 Baseline The baseline condition is represented by the restoration scheme for the Site as presented in CEMEX Drawing P8/530/26/C (Appendix A) as approved by existing planning consent from Wokingham Borough Council (VAR/2006/8160). 1.4 Proposed Change As described above, this application seeks to amend the currently approved restoration scheme for the Site. The changes are restricted to filling in the fringes of the currently approved water bodies to form wetland areas and reedbeds. As such there will be no significant change to the area of water bodies, but the total volume will be reduced. The purpose of this change is to provide a more varied habitat for birds whilst retaining the existing flood storage capacity currently present on the Site. This assessment considers the impact of the revised restoration scheme on the geological, hydrogeological, hydrological and flood risk aspects of the Site. The baseline condition is outlined above, the revised restoration scheme is represented by CEMEX drawing P8/530/26/F dated October 2012. A copy of the proposed revised restoration plan is provided in Appendix B.

1.5 Structure of this Report It is understood that an Environmental Statement is not required for the proposed change to the development, therefore the standard Environmental Impact Assessment (EIA) as described by (Carroll & Turpin, 2009) does not strictly apply, therefore offering a degree of flexibility to the structure of this report. Having considered the relatively simple nature of the proposed change, it is considered appropriate to present a review of the existing geo- environmental setting, followed by an assessment of possible impacts and mitigation between the currently approved and proposed restoration schemes. To avoid unnecessary repetition, where the baseline condition is considered to remain unchanged this will be noted and no further comment will be made. If, based upon ESI’s assessment changes are required to the baseline, based upon the proposed changes to the Site development, further discussion will be provided. The purpose of this report will therefore to be provide clear assessment of geology, hydrogeological, hydrological and flood risk aspects associated with the proposed change to the development in a clear manner for the benefit of Wokingham Borough Council.

2 SITE INFORMATION

The Site covers an area of 52.87 hectares and is situated on the northern bank of the River Blackwater approximately 550 m north of the village of Eversley Cross and 200 m south-east of Finchampstead. The River Blackwater forms the administrative boundary line between the county of Hampshire to the south and the former county of Berkshire to the north. 2.1 A Site location plan is provided in Sensitive Sites The Site does not lie within 1 km of any designated site (e.g. Site of Special Scientific Interest (SSSI); Special protection Area (SPA); Special Area of Conservation (SAC); or RAMSAR site. 2.2 Detailed Site Description ESI representatives undertook a walkover of the Site on 18th November 2013. A Photographic record of the Site visit is provided in Appendix G. At the time of visiting, there was no mineral extraction occurring at the Site and areas were either awaiting restoration or had already been restored. The aggregate conveyer was in place to transport material from the Fleethill Farm site to the west to the processing plant at Chandlers Farm to the south of the Site and River Blackwater. An internal haul road running from the Chandlers Farm site ran in parallel with the conveyor route to allow vehicular access for the importation of restoration materials to the Site. At present the area of the Site east of the conveyer has been restored to a lake in accordance with the approved restoration plan (Appendix A). North of this, the smaller (eastern) portion of the approved reedbed area has already been constructed. West of here, the majority of the Site consisted of one continuous lake water body. The Colebrook Cut watercourse originally flowed from east to west through the centre of the Site, but had been diverted into the River Blackwater upstream of the Site from the Moor Green Lakes in the east. All water draining from the on-site water bodies exits the Site at Longwater Road, re- establishing the Colebrook Cut in the neighbouring Fleethill Farm site to the west.

The local setting of the Site is outlined in Table 2.1 below. Table 2.1 Surrounding land use Site address Manor Farm, Longwater Road, Finchampstead, Berkshire NGR 479987, 162517 Area 52.87 hectares

Topography The topography is flat with an elevation of approximately 50 m Above Ordnance Datum (AOD). Site location The Site situated on the northern bank of the River Blackwater approximately 550 metres north of the village of Eversley Cross and 200 m south-east of Finchampstead. Current Site use The Site has been progressively worked for sand and gravels and is partially restored to a series of lakes. Restoration materials are being imported to the site to achieve the approved restoration landform under an Environmental Permit (recovery) issued by the Environment Agency in December 2010 (Referenced EPR/FP3497SF). ESI visited the Site on 18th November 2013.

3 GEO-ENVIRONMENTAL SITE SETTING

3.1 Topography The elevation of the site ranges from c. 57 maOD in the north east area to c. 48 maOD towards the south west at the downstream end of the River Blackwater adjacent to the Site. The most recent topographical survey for the Site, at the time of writing, was undertaken in October 2013. This shows the Site in its current form, including inactive workings and partially restored areas. It is considered that the existing topography is wholly conducive to both the existing approved restoration scheme (CEMEX Drawing P8/530/26/C (Appendix A)) and the proposed revised restoration scheme (CEMEX Drawing P8/530/26/F (Appendix B)). 3.2 Geology 3.2.1 Information Sources and Previous Site Investigations Regional and local geological conditions have been characterised through a thorough review of available information, including geological mapping, memoirs and previous site investigations. A range of site investigations have taken place at or within close proximity to the Site between 1985 and 2002 (associated with both the Site (Manor Farm) and Chandlers Farm immediately to the south of the Site), information from which has been used to develop a geological conceptual model for the Site. These are detailed in a Borehole Report by Hall Aggregates (South East) Limited on behalf of RMC (RMC, 1995); and include 44 percussive boreholes drilled in 1986 by D K Symes Associates and a further 62 boreholes drilled in 1995 by the Land Search and Exploration department of RMC to check results of previous studies. Details of 74 further boreholes drilled by F.E.S on behalf of CEMEX between 1998 and 2002 are also available. Available borehole logs are provided in Appendix C. The boreholes penetrated to a maximum of 12.2 mbgl. Monitoring boreholes were completed with standpipe installations in order to monitor groundwater conditions, with the majority of installations screened in the River Terrace Deposits and the sands of the Bagshot Bed Formation. Boreholes W01 to W11, CGM01, CGM02, CWG02, CWG03 and CW01 were drilled to greater depths to provide information on water levels in the strata beneath the River Terrace Gravels. These installations were completed with either 2 or 3 water level monitoring pipes installed at different depths, the first one in the gravels, and the others installed within the underlying strata, generally the Bagshot Beds. Logs for the boreholes are presented in Appendix C. The on-Site monitoring locations, and other monitoring locations associated with the Eversley Quarry complex are shown in Figure 3.1.

3.2.2 Regional Geology Information on the regional and local geology near the Site has been taken from British Geological Survey (BGS, 2000), and from the information compiled in support of the Environmental Permit for the Site (Ove Arup & Partners, 2009) and the corresponding Hydrogeological Risk Assessment (ESI, 2009). The regional geology, as shown on the British Geological Survey (BGS) 1:50 000 scale geological map, Sheet 268 (BGS, 2000), is illustrated in Figure 3.2. The stratigraphic succession in the region and in the vicinity of Eversley Landfill, along with a description of the geology types is presented in Table 3.1. The Site is located in the Thames Valley within Recent and Pleistocene gravel deposits associated with the Thames river system. The geological structure of the Thames Valley consists of Quaternary Superficial deposits overlying Eocene and Palaeocene sediments, which in turn unconformably overlie the London Clay formation (BGS, 2000 and Ellison et al., 1999). Superficial deposits in the area comprise a number of River Terrace, Alluvium, Head, Gravel and Langley Silt deposits. The deposits are largely attributed to different watercourses within the region, including the River Thames to the north of the Site (Thames Gravels; including Kempton Park Gravel and Taplow Gravel) and the River Kennet which runs to approximately 19 km east of the site (Kennet Gravels; including Beenham Grange Gravel and Thatcham Gravel). Superficial deposits comprise strata between the First and Fourth series in the vicinity of the site, and are present with Alluvium deposits which are associated with the River Blackwater. Eocene deposits underlie the Superficial Deposits, and they are divided into two distinct formations that comprise sands, pebble beds and clays. The first is formerly known as the Lower, Middle and Upper Bagshot Beds. The unit previously called the Lower Bagshot Beds is now classified as the Bagshot Formation, while the other two units have now been equated to the Bracklesham Group (encompassing the Camberley Sand Formation and the Windlesham Formation). The main outcrop of the formation is centred on Bagshot Heath, near Camberley, where it reaches a maximum thickness of 40 m. Outliers also occur in the Newbury area to the west. The formation is dominated by orange / yellow fine grained sand within thin beds of clay (Jones et al., 2000). The second falls within the Thames Group and comprises the London Clay Formation, which sporadically underlies the Bracklesham and Bagshot Formation and is present up to 100 m thick, thinning towards Reading. The top 10 m of the London Clay may contain a sandy facies known as the Claygate Beds. These beds are present in the Windsor area. The Harwich Formation forms the lowest beds in the Thames Group, although it is not present below the Site. The Eocene strata dip to the east, with a regional dip south eastwards of about 2 to 3 degrees 3.2.3 Local Geology Man-Made Deposits The geological map, Figure 3.2, shows that in the area around the Site there are areas of worked ground. These represent areas of gravel workings and restoration as described above. Restoration materials are being imported to the site to achieve the approved restoration landform under an Environmental Permit (recovery) issued by the Environment Agency in December 2010 (Referenced EPR/FP3497SF)

Report Reference: 60209ABR1 Report Status: Final Manor Farm, Longwater Road, Finchampstead, Berkshire Page 9

Superficial Deposits The Site is situated on, and has extracted gravel from, deposits of the post-diversionary deposits of the River Blackwater, which comprise predominantly angular flint gravels containing fine to medium and coarse silty sand. At the Site they largely consist of Second Terrace Deposits and, to the east of the site, undifferentiated First and Second River Terrace Deposits. Patches of Alluvium consisting mainly of sand, silt, gravel and clay overlie the River Terrace Deposits, and are thickest along the course of the River Blackwater. Layers of peat have been identified in investigation boreholes depths between 0.1 and 0.55 mbgl. Bagshot Formation The Bagshot Formation directly underlies the Superficial Deposits as shown on the BGS (2000) Solid and Drift map, Figure 3.2. This stratum comprises a light brown to dark brown and green / grey fine to medium sand, with silt and clay laminate. It is proven to be present beneath the site with depths between 0.75 mbgl and 9.7 mbgl at W03. To the west, the Bagshot Formation thins due to the eastwards dip of the underlying London Clay. There are outcrops of the Windlesham Formation and Camberley Sand Formation to the north of the Site. These are distinguished by fine grained, yellow and white, slightly ferruginous loamy sand and outliers reach a thickness of up to 20 m in the area. London Clay Formation The London Clay has been proven at depths between 1.5 mbgl at BH20/02 which is located approximately 1.25 km west of the of the Site and 9.85 mbgl at CWG01 approximately 50 m south of the River Blackwater in the Chandlers Farm area. The strata dip to the east. To the west of Longwater Road at Fleethill Farm the Bagshot Beds are largely absent and the London Clay directly underlies the Terrace Deposits. The London Clay consists of blue grey clay, with subordinate silt and fine-grained sand, which is particularly abundant at the base and the top of the formation. Fault Lines The nearest fault runs approximately 370 m northwest of the Site. It is a normal fault and divides the Bagshot formation to the west from the Windlesham and Camberley Sand Formations to the east. 3.2.4 Man-made Subsurface Pathways Monitoring boreholes have been installed into the River Terrace Gravels, with some penetrating the Bagshot Beds to depths varying between 3 mbgl and 12.2 mbgl. The wells have all been constructed with a seal comprising bentonite beneath concrete to prevent surface water entering the borehole annulus. It is unlikely that these boreholes will act as subsurface pathways for water or contaminant migration. Field drains and pipes associated with dewatering are mostly present in alluvial deposits. The most significant of these is the Colebrook Cut which, when reinstated after restoration of the Site, will intersect surface runoff draining from the north of the River Blackwater and flow freely away from the site in an east to west direction. It is possible that the Colebrook Cut may enhance recharge to terrace deposits.

3.3 Hydrogeology 3.3.1 Aquifer Status Both the superficial Sand and Gravel deposits and the underlying solid strata (Bagshot Formation) are described as a Secondary A aquifer. Secondary A aquifers comprise permeable layers capable of supporting water supplies at a local rather than strategic scale and in some cases forming an important source of base flow to rivers. Within the Site the strata are defined as having high and intermediate vulnerability. This status is assigned to strata where there is insufficient low permeability cover to provide protection to groundwater resources from pollution events. There are no designated source protection zones within 500 m of the site. 3.3.2 Aquifer Properties The River Terrace Deposits and Bagshot Formation form the main aquifer within the area. Regionally, the aquifer generally has good quality water which is soft but supplies are not large and abstraction is severely limited by fine silt (Jones et. al, 2000). Springs can occur at the junction with underlying clays. Laboratory falling head permeability data for the Bagshot Beds material used for the construction of bund walls on the southern edge of the flood plain of the River Blackwater, associated with the Chandlers Farm site to the south has been provided by CEMEX (1982). Details of the permeability tests are listed in Table 1.3 (note that the tests were undertaken predominantly on samples that varied between silty sands and clays and, therefore, might not represent the higher permeabilities associated with the sands and gravels). Table 3.2 Permeability of the Bagshot Beds Location number Permeability (m/day) 1 0.01 2 0.30 3 0.35 4 No flow 5 0.10 6 0.09

The permeability encountered varied substantially on account of the geology tested. Tests showed that the clays have very low permeability, not least at location 4 where the clay did not allow any infiltration of water over the measured time period. As expected the permeability of the silty sands is moderate reflecting their grain size and distribution. The overall average permeability of the Bagshot Beds used in bund construction at the Site is 0.14 m/day. Based on particle size distribution data provided by M&B Geotechnical Services (1995) carried out on behalf of CEMEX for boreholes located at the Site, an average of 38.3% gravel, 52.6% sand and 9.1% silt was encountered in samples taken at depths between 1.5 and 3.5 mbgl. The Environment Agency (Thames Region) abstraction register shows up to 37 licences ranging from 1.82 to 655 m3/d, with an arithmetic mean of 76.7 m3/d within 2 km of the site. The high storage combined with a maximum thickness of 25 m, means that abstraction effects on surface water are generally minimal. Small supplies are obtained from the Camberley Sand Formation. Measured borehole yields indicate that 100 m3/d may be obtained, but yields of 50 m3/d are more common (Jones et al, 2000). The major control on permeability and transmissivity of the Bagshot Formation is the lithological variation encountered. As clayey beds overlie many parts of the formation,

Report Reference: 60209ABR1 Report Status: Final Manor Farm, Longwater Road, Finchampstead, Berkshire Page 13

recharge may be limited and this, together with lateral changes in facies is thought to explain why well yields decline with time. 3.3.3 Groundwater Levels and Flow Regionally, groundwater within the River Terrace Deposits and Bagshot Formation is likely to be in hydraulic continuity with various rivers and watercourses that cross the area. These include the River Blackwater flowing from east to west to the south of the Site and various lakes and ponds that have been developed through mineral extraction. Groundwater levels tend to be very close to the river water levels, with lake levels in gravel excavations alongside the river varying from just below to just above the river level depending on the time of year, and rainfall recharge. Given the various groundwater levels observed it is probable that in the region in and around the Site area groundwater flows from north to south with local influence of lakes and ponded areas. The presence of the water filled excavations at the Site will exert a significant influence on the regional flow regime. Groundwater levels have been monitored at the Site and the wider Eversley Quarry complex since April 1998 at a total of 33 locations. Monitoring locations are displayed on Figure 3.1, and respective groundwater levels for locations closest to the Site are displayed in Appendix E. Groundwater monitoring locations at the Site include: Northern Boundary: W01 (A, B & C), W02 (A & B), W03 (A, B & C), W04, A & B), W05 (A, B & C), W06 (A & B), W07 (A, B & C), W08 (A & B). Eastern Boundary: W09 (A & B). Western Boundary: W12. Southern Boundary: CW01 (A & B). Groundwater levels are relatively consistent throughout the monitoring period, showing seasonal fluctuation and occasional sharp declines during periods when groundwater dewatering has been undertaken at the Site. All hydrographs show groundwater levels to recover to their pre-dewatering condition following cessation of dewatering. Based upon available monitoring data, it can be summarised that the groundwater is in hydraulic continuity within both the superficial strata, the Bagshot formation and surface water. Groundwater levels locally below the Site fall to the south, consistent with a regional hydraulic gradient towards the River Blackwater. In a wider context groundwater levels also fall to the west, again consistent with the topographical fall and levels in the River Backwater which are provided in hydrographic form in Appendix H. 3.3.4 Licensed Groundwater Abstractions There are three licensed groundwater abstractions within 1 km of the Site application area.

3.3.5 Private Water Supply Historically there have been private water supplies at Foxglade Farm, Moor Green Farm, and Mayfield and Pithers Cottage, located on Lower Sandhurst Road to the north of the Site. Previously Foxglade Farm, Mayfield and Pithers Cottage have been monitored. It is understood that only one is currently used for private supply, at Foxglade Farm. 3.3.6 Groundwater Quality The River Terrace Deposits and Bagshot Formation are in hydraulic continuity and form the main water-bearing unit at the Site. Literature reports the River Terrace Deposits and Bagshot Formation groundwater is generally of good quality water which is soft but supplies are not large and abstraction is severely limited by fine silt. Within the Site low pH, elevated electrical conductivity, elevated iron and sulphate have been observed in groundwater. The low pH is considered to be due to the influence of peat below the topsoil and oxidation of iron minerals from the underlying formations. The results show that the groundwater quality in the Site area is generally poor, considered to be due to natural, rather than anthropogenic, causes. Groundwater quality data for the Site is presented in Appendix F for monitoring points in and in the vicinity of the Site. Ove Arup & Partners (2009) describe groundwater quality at the Site to be generally poor with low pH leading to naturally elevated levels of metals and other determinands. Groundwater quality is typically of higher quality in locations to the north of the Site. These locations are generally above the flood plain, up hydraulic gradient of the site, and away from the area of alluvium and peat, that is postulated to cause the observed low pH and high iron and manganese concentrations. Most elevated concentrations are measured at locations W08 to W09, W12 and CW01. W08 is situated farthest from the facility and the other locations are located along the River Blackwater. A number of metals; iron, manganese, lead, nickel, magnesium and potassium remain in exceedence of respective Drinking Water Standards (DWS) across much of the Site (Appendix F). This is consistent with observations presented by Ove Arup & Partners (2009) and ESI (2009) which considered these elevated concentrations to be naturally occurring. pH (laboratory) in groundwater for the boreholes summarised in Appendix F indicates a mean pH of 5.2 (Max: 8.5; Min: 2.3). This is consistent with Ove Arup & Partners (2009) and ESI (2009) in that conditions are generally acidic with some locations presenting significantly more acidic conditions. Ammoniacal Nitrogen and Nitrite remain elevated in a number of locations, giving rise to the elevated conditions indicated in Appendix F. This is consistent with the observations presented by Ove Arup & Partners (2009) and ESI (2009) and may be attributed to agricultural land use and naturally occurring organic deposits across the Site.

Report Reference: 60209ABR1 Report Status: Final Manor Farm, Longwater Road, Finchampstead, Berkshire Page 15

Sulphate remains remain elevated in a number of locations, giving rise to the elevated conditions indicated in Appendix F. This is consistent with the observations presented by Ove Arup & Partners (2009) and ESI (2009) and may be attributed to naturally occurring conditions within local geological strata. In summary, groundwater conditions summarised in Appendix F indicate no significant change from those reported by Ove Arup & Partners (2009) and ESI (2009) and therefore no change to the baseline condition presented by the existing planning consent and approved restoration. The data suggest that groundwater local to the site is naturally not of a particularly high quality. There is no evidence to suggest that groundwater quality has been detrimentally affected as a result of activities at the Site since the granting of the existing planning consent, nor is there any case to suggest that groundwater quality will be affected detrimentally by the proposed changes to the Site restoration. Groundwater monitoring will remain a reportable requirement under the conditions of the Environmental Permit for the importation of restoration materials to the Site. 3.4 Hydrology 3.4.1 Climate The long term average rainfall and actual evaporation data have been obtained for a 40 km MORECS Square 160, in which the site is located. The average rainfall and hydrologically effective rainfall for the period 1971 to 2000 are 693.6 and 190.8 mm/a respectively. These data are presented in Table 3.4.

3.4.2 Surface water features A total of three small streams originate to the north of the site and flow in a southerly direction towards the Manor Farm area. The main features receiving surface water around the application area are a series of streams, drains, rivers and ponds, which channel and store surface water runoff. The proposed changes to the restoration of the Site involve creating a reedbed habitat within open water ponds that are already approved. There will be no changes to the layout or general interaction of water flow between the surface water features at the Site in the approved and proposed restoration plans. The Colebrook Cut was once the main drainage feature in the Site and was formerly situated approximately 200 m north of the River Blackwater to drain the agricultural land north of the river. Shortly after the commencement of gravel excavation in Manor Farm in 1999, the Colebrook Cut was diverted to the east of Manor Farm into Moor Green Lakes, and then via a culvert to the River Blackwater from the south-western corner of the Moor Green Lakes. The River Blackwater flows from east to west adjacent to the southern boundary of the Site but there is no direct surface water connection between the Site and this main river.

Report Reference: 60209ABR1 Report Status: Final Page 16 Manor Farm, Longwater Road, Finchampstead, Berkshire

Surface water currently drains into the former quarry pits which have been left as open water lakes, reedbed and wetland areas. In the south east of the Site (east of the aggregate conveyer) there is a small lake with marginal reedbed areas in line with the approved restoration plan. In the proposed restoration scheme this water body will be partially filled with additional inert material brought on site to create more reedbed / wetland habitat for birds. To the north a reedbed area has already been developed in line with the approved plan. The fringing of the reedbed edges (see photo in Appendix G) is representative of what the proposed scheme aims to achieve in the southern areas of the site. The inert material has been placed beneath the level of the surface water and this is what is being proposed to create the reedbed fringing in the southern areas of the Site. It is also intended to reinstate the Colebrook Cut around this feature which will then flow westwards through Manor Farm towards a culvert beneath Longwater Road through which it has historically run. There is a raised bank between the open water in the south and the constructed reedbed in the north. The raised bank represents the original ground level and is approximately 1 metre above the soil height of the planted areas in the reedbed feature. Staining observed on the reeds, during the site visit, indicated water levels are subject to fluctuation. From the western boundary of the Site there is a large lake that extends upstream about two thirds of the length of the entire Manor Farm site. At this western end, the pond water level is relatively high compared to the land level as it is supported by groundwater inflow from up hydraulic gradient. The nearby sewage works is the closest building down gradient of the site (see Figure 2.1) and was observed to be c. 0.5 m above the water of the adjacent large lake during the Site visit. 3.4.3 Licensed Surface Water Abstractions There is one licensed surface water abstraction from the River Blackwater approximately 13 m south of the Manor Farm boundary. The licence is used occasionally for a groundwater recharge scheme just to the north of the northern boundary of Manor Farm. This is to ameliorate the effects of the dewatering of the excavation on groundwater levels near to houses in Cricket Hill in Finchampstead.

3.4.4 Discharge Consents There are 11 consented discharges to surface water within 2 km of the Site. A single discharge consent is held for the Eversley Quarry complex which is licensed for a daily discharge amount of 24,240 m3/d. Details of consented discharges are summarised in Table 3.6.

3.5 Flood Risk 3.5.1 Fluvial flood risk According to the maps provided by the Environment Agency, most of the site lies within an area of high risk in Flood Zone 3, with scattered areas in the northwest classified as medium risk Flood Zone 2. Towards the northeast, flood risk is predominantly low and the designation is Flood Zone 1 in this location. The extent of the latest modelled flood zones are shown in Figure 3.3. The EA have also provided modelled flood elevations for the stretch of the River Blackwater adjacent to the site. Modelled levels for the Site range from 51.48 maOD (downstream) to 52.80 maOD (upstream) for the 1 in 100 year +20% CC event. The extent of the latest modelled flood zones are shown in Figure 3.3 and the flood outline covers almost the entire Site. Further details on the EA modelled flood elevations can be found in Appendix D.

Report Reference: 60209ABR1 Report Status: Final Page 18 Manor Farm, Longwater Road, Finchampstead, Berkshire

Areas to the east and southeast of the site, which comprise Moor Green Nature Reserve and parts of Chandlers Farm, are designated as flood storage areas. There are no flood defences within 250 m of the site For comparison with the EA flood modelling data, the 2009 level monitoring data from CEMEX for the River Blackwater is presented in Figure 3.4. These data were recorded at the bridge where the aggregate conveyer crosses the River Blackwater from Manor Farm to the processing plant at Chandlers Farm, where an automatic logger collects data at 15 minute intervals. The comparable EA modelled flood elevation at this location is 52.80 maOD for the 1 in 100 year +20% Climate Change event is taken from model node 06324_MN_BL2_02.046. The proposed works have been reviewed in light of the new National Planning Policy Framework Technical Guidance (2012) and they are considered to remain acceptable under the new guidance. Fluvial flood risk is the main issue at the site, however sand and gravel workings are classed as water compatible developments which are appropriate for locations in Flood Zone 3 without the need for an exception test. 3.5.2 Other sources of flooding The Site is considered at low risk from other sources of flooding. Surface water (pluvial) flooding is usually associated with extreme rainfall events but may also occur when rain falls on land that is already saturated or has a low permeability. Rainfall that is unable to infiltrate into the ground generates overland flow which can lead to flooding or ‘ponding’ in localised topographical depressions before the run-off is able to enter the drainage system or watercourse. The risk of surface water flooding is considered low as systems are in place to manage water throughout the restoration of the Site. The landform within the Site boundary will be restored to ensure adequate site drainage and will include suitable run-off attenuation features. Groundwater flooding occurs when the water table rises above the ground surface or into man-made ground. Groundwater has been monitored extensively around the Site during the operation of the Site and has shown that groundwater levels are below ground level. Whilst parts of the site in the proposed restoration plan are intended to be wetlands and are below this level the raised parts of the site will generally be 1 - 2 m above the groundwater level. Groundwater is unlikely to rise above the proposed land surface because of the proximity of the surface water streams and the River Blackwater, and drainage systems proposed for the reedbed management. The Site is located on a secondary aquifer and in some locations groundwater levels will be shallow. However, the proposed site after use is not considered sensitive to a shallow water table and the overall risk is therefore considered low. There are extensive areas of stored water upstream of the site but these are all at ground level and not impounded. They are therefore not potential sources of catastrophic flooding. The Environment Agency flood maps show no flood risk due to reservoir failure on the Blackwater and there are no other likely sources of stored water upstream that could threaten the site. It is therefore concluded that the site is not at risk from reservoir failure. 3.5.3 Designated Environmentally Sensitive Areas There are no designated environmentally sensitive areas within 500 m of the Site. .

4 CONCEPTUAL MODEL

4.1 Activities The Site has been worked for superficial sand and gravel deposits under appropriate planning consents, however sand and gravel extraction has now ceased. A substantial area of the Site has already been restored in compliance with the existing restoration scheme (Appendix A) Restoration materials are presently being imported to the site to achieve the currently approved restoration landform under an Environmental Permit (recovery) issued by the Environment Agency in December 2010 (Referenced EPR/FP3497SF). Further importation of restoration materials will also be conducted under appropriate regulatory consent from the Environment Agency. The revised restoration scheme (Appendix B) proposes relatively minor changes to the existing restoration scheme. 4.2 Water balance Water will infiltrate through the top of the restored areas of the Site and to surface water bodies. Surface water bodies within and adjacent to the Site are considered to be in hydraulic continuity with groundwater in superficial deposits. Water will seep into the restoration soils where it will be subject to evaporation and use by plants (transpiration). These two processes are often jointly referred to as evapotranspiration. The maximum amount of infiltration to much of the Site is controlled by the vertical permeability of the restoration materials. If the potential infiltration flux exceeds the vertical permeability of the waste, the excess water will run off. During summer the evapotranspiration demand may be higher than rainfall, whereas during winter rainfall may be greater than the evapotranspiration. For this reason in summer all the rainfall is usually accounted for, while during winter months the excess water percolates downwards deeper into the soil zone, where lateral movement of this water is likely to occur due to local heterogeneity in the soil zone. Due to the geometry of the site, any water that enters the Site will either discharge to River Blackwater, via shallow groundwater pathways or exit the Site via the Colbrook Cut. 4.3 Potential source, pathway, receptor linkages The conceptual model can be described in terms of potential sources of contamination, receptors and pathways that link the sources to the receptors. The potential source of contamination relates to the continued restoration of the Site and imported restoration materials. The receptors of concern are groundwater and surface water. Pathways are likely to include:  pathway from source to surface water,  pathway from source to surface water via groundwater and  pathway from source to groundwater.

5 OPERATIONS, IMPACTS & MITIGATION

5.1 Operational Activities with Potential to Affect Groundwater and Surface Water The sequence of activities at the site is to progressively infill / restore remaining areas as per the existing planning consent (Appendix A), and to modify a number of surface water bodies to form increased reedbed area as proposed by the plan in Appendix B. All waste importation will be undertaken in accordance with the existing Environmental Permit. The operator is currently monitoring groundwater and surface water at a number of on-Site and off-Site locations as indicated in the preceding section. Groundwater and surface water monitoring is undertaken as a requirement of the Environmental Permit to ensure that the importation of restoration materials does not cause any deterioration to natural water quality. This monitoring will continue to ensure mitigation of risk to controlled waters. 5.2 Discussion of Potential Impacts and Mitigation 5.2.1 Colebrook Cut Diversion & Removal of Internal Site Drains and Ditches There are no changes from CEMEX Drawing P8/530/26/C (Appendix A). 5.2.2 General Site Activities – Plant and machinery There are no changes from CEMEX Drawing P8/530/26/C (Appendix A). 5.2.3 Revised Restoration Scheme to Lakes – Impact on Surface Water Flows and Water Levels A number of changes are proposed from the currently approved Site restoration scheme (Appendix A). The proposed scheme includes increased wetland and reedbed habitat and aims to achieve more ecological value for the site (Appendix B). Figure 5.1 highlights the key areas of change between the approved and the proposed restoration schemes (circled). Additional inert material will be brought onsite and distributed in a way that increases the surface area of the lake banks to create a more varied reedbed habitat for reed plants to become established upon. The material will be placed within these water bodies in such a way that it does not raise the ground surface above the original water level prior to the original mineral extraction. There should therefore be no reduction in flood storage here since no land raising will be taking place above the water surface across the entire Site and the proposed flood storage areas will still intercept the same volume of flood water across the Site within the area of the predicted flood outlines which cover the site extensively for the 1 in 100 year and 1 in 1000 year flood events (Figure 3.3). The volume within the active flood zone may actually reduce (between the flood level and the ground and lake surface) providing additional flood storage. Once the compartmentalising of the Site, with the reedbeds, is established, the groundwater table should better reflect the slope down the main river valley and the imported substrate within which the reeds will grow should be submerged most, if not all, of the year. There is a slight reduction in planted shrub vegetation in the new proposed restoration scheme but the impact of this is not deemed significant when the Site is considered as a whole. It is noted that there are no proposed changes to the locations of surface water inflows and outflows to and from the Site. In the new proposed restoration scheme, the final ground levels are still lower than or equal to the original ground level and there is no proposed raising of ground levels above the pre extraction ground elevation across the Site. This will result in a net increase in flood storage and a reduction in flood risk to downstream receptors.

5.2.4 Final Restoration Scheme – Water Quality Considerations The operator is currently monitoring groundwater and surface water at a number of on-Site and off-Site locations as indicated in the preceding section. Groundwater and surface water monitoring is undertaken as a requirement of the Environmental Permit to ensure that the importation of restoration materials does not cause any deterioration to natural water quality. This monitoring will continue to ensure mitigation of risk to controlled waters.

6 CONCLUSIONS & RECOMENDATIONS

6.1 Conclusions Potential impacts to groundwater and surface water have been assessed as those typically associated with restoration activities and the importation of suitable restoration materials. It is considered that by following the conditions defined in the Environmental Permit, continuing to operate the environmental monitoring network and applying industry good practise, all the identified risks can be mitigated against. It is considered that the proposed changes to the development do not present a significant risk to the geological, hydrogeological and hydrological environment, and the risk of flooding is not considered to be substantially increased.
