Notes: Excludes stratigraphical units that are absent from the study area. Stratagraphical thicknesses have been taken from Geological Maps.

A2.4.1.2 The study areas for Locations A and C are situated on the southern limb of the London Basin syncline, which include the strata up to the Thames Group. The strata dips very gently to the northwest at generally less than 2 degrees. Unconformably overlying the Upper Chalk in the central part of the London Basin are Palaeogene deposits, which are mainly comprised of the Thanet Sand Formation and Lambeth Group, these are dominated by sands and clays. The Thames Group (mainly the London Clay Formation) is also present, although mainly in the area north of the A13.

A2.4.1.3 The Palaeogene and Late Cretaceous deposits are overlain in places by Quaternary deposits mainly of Alluvium (with peat lenses and beds), River Terrace and Head Deposits. The Alluvium deposits are most evident along the River Thames channel and subsidiary river channels, such as the Mardyke and the River Darent. The River Terrace Deposits are also present in places below the Alluvium to varying thicknesses. River Terrace Deposits dominate the hill tops and higher ground, especially to the north and also to the south of the River Thames valley.

A2.4.1.4 In the north, generally north of the Mardyke channel, around Ockendon but also continuing eastwards to Orsett, the London Clay Formation is present below the River Terrace and Head Deposits. It is shown in outcrop in many places where there have been old quarries and pits. However, most of these areas are shown on the geological maps as Worked Ground (described as mainly chalk, sand and gravel pits with little or no fill), and as Worked Ground and Made Ground (described as wholly or partly backfilled pits). The natural London Clay outcrops begin to appear intermittently around North Ockendon and become more regular in the far north of the study are near Little Warley along the A127 and to the east of the A128.

A2.4.1.5 South of the Mardyke Valley and north of the West Thurrock and Tilbury Marshes, the higher ground and hill tops consist of River Terrace Deposits overlying the Lambeth Group and Thanet Sand Formation; these in turn unconformably overlie the Upper Chalk Formation. In the West Thurrock area, where the land slopes gently towards the West Thurrock Marshes, the Upper Chalk is shown in outcrop. Although most of the area is shown as Worked Ground, which is described as mainly chalk, sand and gravel pits with little or no fill on the geological maps and Worked Ground and Made Ground, which is described as wholly or partly backfilled pits. Similarly on the south side of the River Thames Valley the Upper Chalk outcrops on the lower sides of the hills, although in the western area from Swanscombe to Dartford it is shown with hatching identifying Worked Ground and Worked Ground and Made Ground.

A2.4.2. Mining A2.4.2.1 Quarrying of sand and gravel for building materials and the excavation

of chalk and clay for the manufacturing of cement was extensive either side of the River Thames, the majority of which has now ceased. The chalk quarries, of which there are many between the A13 in the north and the A2 in the south, were 25m deep or more. Since the end of manufacture of cement the quarries have either been backfilled with waste, left as water- filled lakes or been redeveloped for industrial, retail and residential development.

A2.4.2.2 Chalk extraction in the area has not just been limited to open quarries. Numerous deneholes and even underground mines (beneath Dartford) are present throughout the area from the A13 south to the A2. Deneholes comprise a small shaft excavated down to the chalk off which small adits were driven. The chalk mining in this way was undertaken in medieval times and was used for liming agricultural fields. Some deneholes are known to have been constructed in pre-Roman times. The location of deneholes is very difficult to predict and several of these were encountered during the construction of HS1.

A2.4.2.3 North of Junction 30 (M25), gravel, sand and clay extraction was extensive. In many locations the underlying deposits of London Clay have been excavated for cement production, in particular north of South Ockendon. The mining that occurred around Ockendon reached its zenith post 1920. At one point 1.5 million tonnes were extracted per annum from a quarry. The clay was mixed with water to turn it to slurry, allowing it to be pumped to a cement plant in Grays initially, and later to a plant in Northfleet for addition to the raw cement mix. This involved an 11km pipeline beneath the Thames. As aforementioned the remains of these pits are depicted as outcropped London Clay or worked ground due to the majority being backfilled with landfill material. Information provided by the current landfill operator during previous studies suggests the backfilled pit known as Area 3 at Ockendon was licensed to accept hazardous waste within the last 40 years in the form of asbestos and liquid toxic for a period of time after changes in legislation. Area 3 is still operational and is planned to be extended to the east, although it does not accept hazardous waste anymore. It is unknown when this ceased and the amount of waste accepted.

A2.4.2.4 Other areas of chalk, sand and gravel extraction have occurred near the A2 at Shorne, the surrounding land between East Tilbury and Chadwell St Mary and around Junction 30 of the M25 and along the A13. The majority of these have been backfilled with landfill material.



Appendix 2.5 Existing UtilitiesExisting Utilities



Existing Utilities A2.5.1.1 Existing utility information has been obtained from utility companies

for Locations A and C. This process has identified the location and type of significant utility infrastructure within the Study Area. The key utilities are described below.

Location A A2.5.1.2 On the south side of the River Thames there is a sub-surface medium

pressure gas pipeline crossing beneath existing A282 on the approximate line of Bow Arrow Lane south footway.

A2.5.1.3 On the south side of the River Thames there is one or more sub-surface oil pipeline(s) at Junction 1a crossing the A282 roughly perpendicular to the carriageways. The depth of the oil pipeline(s) is currently unknown.

A2.5.1.4 On the south side of the River Thames is an existing high voltage overhead electricity line that originates from Littlebrook Power Station. The electricity line crosses over Junction 1a in the east-west direction and again at a skew in the north-west direction around the fast track bus route.

A2.5.1.5 On the north side of the River Thames there are overhead electricity lines that cross existing A282 between Junction 31 and Junction 30.

A2.5.1.6 There is a National Grid underground power cable tunnel (Dartford Cable Tunnel) crossing the river and running parallel approximately 120m to the west of the existing Dartford west tunnel. It is understood to carry National Grid high voltage cables and underground cables (including those associated with the existing tunnel ventilation buildings) and drainage.

A2.5.1.7 On the north side there are various sub surface national grid conductors and high voltage cables.

A2.5.1.8 Other utility infrastructure within Location A includes low voltage cables, fibre optic cables, telephone lines, drainage pipes, technology and lighting cabling and infrastructure.

Location C A2.5.1.9 On the south side of the River Thames are overhead electricity lines

and a major gas pipeline. Adjacent to the A2 near Cobham London Road services there is a large electricity pylon and associated overhead cables. These overhead cables go north over the A2, approximately 1km to the east of Chalk and then over the Thames and Medway Canal west of the railway sidings.

A2.5.1.10 There are overhead cables from the east which generally run parallel with the Thames and Medway Canal and these cables connect into a large pylon on the south bank of the River Thames to the east of the Metropolitan Police Specialist Training Centre. At this point the cables go beneath the river in a cable tunnel in a north westerly direction towards Tilbury power station.



A2.5.1.12 On the north side of the river there are a large number of overhead cables that originate at Tilbury power station and run north. A2.5.1.13 The gas pipeline from south of the river runs between West Tilbury and

and East Tilbury and then north, eventually crossing the A127 to the east of the A127/ A128 grade separated junction.

A2.5.1.14 Within Location C there is a significant amount of other utility infrastructure, this includes low voltage cables, fibre optic cables, telephone lines and sewer pipes.

gas pipeline that runs under the A2 and north east towards the river where it crosses the river via a tunnel towards Coalhouse Fort.

A2.5.1.11 On a similar alignment to the overhead cables there is a National Grid



Appendix 2.6 Highway and River Operation and Maintenance Highway and River Operation and Maintenance



Highway and River Operations and Maintenance A2.6.1 Highway Operations and Maintenance A2.6.1.1 LTC would interface with and affect strategic roads in two Highways

England maintenance areas, Area 4 and Area 5 as shown in Figure 1. A2.6.1.2 Area 4 is maintained by A-one+ Integrated Highway Services (Colas/

Costain/ CH2MHill) on behalf of Highways England. A2.6.1.3 Area 5 is maintained by Connect Plus under the M25 DBFO Contract, a

30 year concession contract which commenced in 2009. This includes the operation and maintenance of the Dartford Crossing and its approaches.

FIGURE 1 - EXTENT OF M25 DBFO AND AREA 4 CONTRACTS

A.2.6.1.4 At present, the motorway network is accessed via short/medium termstops on the hard shoulder or under traffic management following the road space booking procedure. Off network access is also used in some locations.

A.2.6.1.5 At the Dartford Tunnels, maintenance is undertaken during plannedclosures. On the QEII Bridge, maintenance is carried out during lane closures or full bridge closures.

A.2.6.1.6 The existing tunnel system includes fire detection and suppressionsystems, public address (PA) system, lane control signs, Communications/SCADA (Supervisory Control and Data Acquisiton), emergency services radio/telephone re-broadcast system, tunnel specific CCTV, drainage & pumping systems, ventilation and road lighting and emergency lighting. This is operated from the Dartford River Crossing Control Centre (DRCC) which is located adjacent to the southern end of the crossing. There are two compounds where



Highways England Traffic Officers and Traffic Management (TM) crews are located to provide immediate assistance for incidents on the crossings. Additionally there are twelve observation points at the extents of the crossing which Highways England Traffic Officers can use to gain access to the crossing to assist road users. There is currently a northbound and a southbound depot which have a TM crew and Traffic Officers on site to enable small incidents to be dealt with quickly on site. Communication with the Highways England Traffic Officers and TM crews is managed by Connect Plus via the DRCC.

A2.6.2 River Operations A2.6.2.1 The River Thames is Britain’s busiest inland waterway, handling some

50m tonnes of cargo each year and contributing over £3bn to the economy annually. Each year 230,000 commercial and leisure vessels pass within the Port of London’s 95 miles of river and estuary between Teddington and the North Sea. Of these, 10,000 larger vessels are guided by Thames pilots annually.

A2.6.2.2 Marine traffic information produced by the Port of London Authority (PLA) consisting of shipping data from May 2011 to January 2015 has been analysed for each of the locations being considered.

Location A A2.6.2.3 The number of vessel movements along the River Thames at Location

A are summarised in Figure 2:

A2.6.3 Future Marine Traffic A2.6.3.1 At present limited information is available on the future development

anticipated in: - The ports and berths along the River Thames.- The volume of marine traffic navigating the locations.- The size of the vessels navigating the locations.

A2.6.3.2 This information is in the process of being requested from relevant stakeholders under the stakeholder engagement process. In the absence of this information, a functional assessment of the river channel, constraints and physical limitations has been undertaken to determine the initial design vessels that can traverse the river and use the terminals.

A2.6.3.3 Based on the information currently available, the minimum air draft clearance for shipping at Location A is 57.5m AOD over a clear width of 100m and 50m AOD over an additional 205m. Bridge pylon foundations would likely require to be designed for similar levels of accidental ship collision as the existing crossing (accidental head on impact of a 65,000 Dead Weight Tonnage (DWT) vessel fully laden or

foundations would likely require to be designed for similar levels of accidental ship collision as the existing crossing (accidental head on impact of a 65,000 Dead Weight Tonnage (DWT) vessel fully laden or in ballast approaching at 10 knots).

A2.6.3.4 Based on the information currently available, the minimum air draft clearance for shipping at Location C is assumed as 75.19m AOD over a clear width of 305m. Bridge pylon foundations located in the river would require to be designed to resist the accidental ship collision loads. For a structure spanning approximately 800m at Location C, the likely design vessel is assessed as a 120,000 DWT vessel fully laden or in ballast approaching at 10 knots. If the span is reduced and the main pylon foundations moved to deeper water then the likely design vessel is assessed as increasing to 145,000 DWT vessel fully laden and in ballast.

A2.6.3.5 The final design vessels would be determined from a risk analysis which would be undertaken if a bridge solution is selected.
