12.3.10 The Proposed Scheme also crosses the Grand Union Canal. There are no other navigable waterways that cross the Proposed Scheme, in this area.

Future baseline 12.3.11 The future baseline traffic volumes for the M25 and M25 slip roads have been derived from the Highways Agency’s M25 transport model, for the future years 2021, 2026 and 2041.

12.3.12 Future baseline traffic volumes have been obtained from Transport for London’s

WeLHAM highway model for 2021, 2026 and 2041 for the following roads:

 Harvil Road;

 B467 Swakeleys Road; and  A40 Western Avenue.

12.3.13 The future baseline traffic volumes for all other roads have been calculated by applying growth factors derived from TEMPRO for 2021, 2026 and extrapolation to

2041. The factors have been derived for the individual road types and relevant wards.

No other changes to the traffic and transport baseline are anticipated in this area.

CFA Report – Colne Valley/No7 | Traffic and transport

Construction (2017 to 2025) 12.3.14 Construction activities have been assessed against 2021 baseline traffic flows, irrespective of when they occur during the construction period. Future baseline traffic volumes in the peak hours are forecast to grow by 10% to 11% by 2021 compared to 2012, depending on road type.

Operation (2026) 12.3.15 Future baseline traffic volumes in the peak hours in this area are forecast to grow by 16% to 17% by 2026 compared to 2012, depending on road type.

Operation (2041) 12.3.16 Future baseline traffic volumes in the peak hours in this area are forecast to grow by 27% to 33% by 2041 compared to 2012, depending on road type.

Effects arising during construction 12.4 Avoidance and mitigation measures 12.4.1 The following measures (as detailed in Section 2) have been included as part of the engineering design of the Proposed Scheme that will avoid or reduce impacts on

transport users:

 provision of one sustainable placement area used for excavated materials in the Colne Valley area (three others are located in CFA6) which reduces HGV movements on public roads within the area and in CFA6;

 construction materials and equipment will be transported along a haul road within the land required for construction where reasonably practicable, to reduce lorry movements on the public highway;

 the majority of roads crossing the Proposed Scheme will be kept open during construction resulting in reduced diversions of traffic onto alternative routes.

Alternatives will be provided prior to any closures;

 providing temporary alternative routes or building structures early to maintain connectivity for PRoW closed during construction to reduce loss of amenity.

Alternatives will be provided prior to any closures;

 providing on-site accommodation and welfare facilities to reduce daily travel by site workers; and  HGV routeing as far as reasonably practicable along the strategic road network and using designated routes for access, as shown on Map TR-03-051 (Volume 5, Traffic and Transport Map Book).

12.4.2 The draft CoCP (see Volume 5: Appendix CT-003-000/1) includes measures which seek to reduce the impacts and effects of deliveries of construction materials and equipment, including reducing construction lorry trips during peak background traffic periods. The draft CoCP includes HGV management and control measures.

12.4.3 Where reasonably practicable, the number of private car trips to and from the site (both workforce and visitors) will be reduced by encouraging alternative modes of CFA Report – Colne Valley/No7 | Traffic and transport

–  –  –

Construction and operational travel plans will promote the use of sustainable transport modes as appropriate to the location and types of trip.

They will include measures such as: provision of information on and promotion of public transport services; provision of good cycle and pedestrian facilities; liaison with public transport operators; promotion of car sharing; and the appointment of a travel plan coordinator to ensure suitable measures are in place and are effective.

CFA Report – Colne Valley/No7 | Traffic and transport

12.4.8 Construction vehicle movements required to construct the Proposed Scheme include the delivery of plant and materials, movement of excavated materials and site worker trips.

12.4.9 Details of construction compounds are provided in Section 2. The duration of when there will be busy transport activity at each site is shown in Table 20. This represents the periods when the construction traffic flows will be greater than 50% of the peak flows. Also shown is the estimated number of daily vehicle trips during the peak month of activity. The lower end of the range shows the average number of trips in the busy period and the upper end shows the average during the peak month.

In assessing significant effects of traffic changes on congestion and delays, a major adverse effect occurs where traffic flows at a junction will be beyond or very close to capacity with the Proposed Scheme and the increases in traffic due to the Proposed Scheme will be such as to substantially increase queues and delays on a routine basis at peak times. A moderate adverse effect will occur when traffic flows at a junction will be approaching or at capacity with the Proposed Scheme and modest increases in traffic will increase the frequency of queues and more substantial delays. A minor adverse effect occurs when traffic flows at a junction are not generally exceeding capacity with the Proposed Scheme but the increase in flows will result in occasional queues and delays or small increases in existing delays.





In the context of this traffic and transport section, Severance is used to relate to a change in ease of access for non-motorised users due to, for example, a change in travel distance of travel time or a change in traffic levels on a route that makes it harder for non-motorised users to cross. A reference to severance does not imply a route is closed to access.

CFA Report – Colne Valley/No7 | Traffic and transport

12.4.19 No significant effects on parking or loading have been identified during construction in this area.

12.4.20 The effect on accident and safety risks will not be significant as there are no locations where there are both accident clusters and substantial increases in traffic during construction.

12.4.21 Temporary PRoW diversions in this area during construction will have minor adverse effects on severance for non‐motorised users due to temporary PRoW realignments of bridleway DEN/2 ‐Shire Lane and footpath U75 – Colne Valley Trail (footpath, bridleway, cycleway) with the length of diversions being between 600m and 1.2km.

Additionally there will be temporary closures of bridleway DEN/3, bridleway Rickmansworth 004 and footpath U75 (Grand Union Canal tow path).There will be moderate adverse effects due to the temporary PRoW diversion at Chalfont Lane, with the length of diversion being approximately 2km, CSP/44 with a diversion of approximately4.8km, and Shire Lane (bridleway CSP/43/2) with a diversion of 1.2km.

12.4.22 There will be no traffic and transport effects on navigable waterways within this area.

Cumulative effects 12.4.23 The assessment includes the cumulative effects of planned development during construction by taking this into account within the background traffic growth.

12.4.24 The assessment also includes in combination effects by taking into account construction traffic and transport impacts of works being undertaken in neighbouring areas. From the adjacent areas to the north including the Chalfonts and Amersham area (CFA8), the Central Chilterns area (CFA9) and the Dunsmore, Wendover and Halton area (CFA10) the combined construction traffic flows of approximately 102 cars/LGVs per day (two-way) and 9 HGVs per day (two-way) have been included in the assessment for this area.

12.4.25 From neighbouring areas to the south-east the combined construction traffic flows of up to 460 HGVs per day (two-way) have been included in the assessment for this area.

Permanent effects 12.4.26 Any permanent effects of construction have been considered in the operations phase assessments for traffic and transport in Section 12.5. This is because the impacts and effects of the on-going increases in travel demand and the wider impacts and effects of the operations phase need to be considered together.

Other mitigation measures 12.4.27 The implementation of the draft CoCP (see Volume 5: Appendix CT-003-000) in combination with the framework travel plan and the construction workforce travel plan will, to some degree, mitigate the transport related effects during construction of the Proposed Scheme. The reductions in effects arising from these travel plan measures have not been included in the assessment, which will mean that the adverse effects may be over-stated.

CFA Report – Colne Valley/No7 | Traffic and transport 12.4.28 No further traffic and transport mitigation measures during construction of the Proposed Scheme are considered necessary, based on the outcome of this assessment.

Summary of likely significant residual effects 12.4.29 Increased traffic during the most intensive periods of construction, particularly HGV traffic, will affect non-motorised users crossing and using; Hornhill Road through Maple Cross; Woodland Road; Chalfont Road, between Hornhill Road and A412 Denham Way; Denham Green Lane; Slip roads onto A40 from Swakeleys roundabout;

Swakeleys Road, between A40 and Harvil Road; and Harvil Road, south of Moorhall Road.

12.4.30 Increased traffic during the most intensive periods of construction will also potentially cause additional intermittent traffic congestion and delay at a number of junctions in the area, including the A412 Denham Way with Chalfont Lane, A412 North Orbital Road with Woodlands Road, A412 North Orbital Road with Chalfont Road; A412 Denham Way with A404 North Orbital Road; A412 North Orbital Road with Denham Green Lane; Harvil Road with Woodstock Drive; B467 Swakeleys Road with Harvil Road and A40 Western Avenue with B467 Swakeleys Road.

12.4.31 Temporary closure of Chalfont Lane and Tilehouse Lane during construction will cause some additional delay for users of these roads due to the additional travel distance required by the associated diversions whilst in operation.

12.4.32 Temporary closure of five PRoW, including roads, during construction will affect the relatively few non-motorised users due to the increased travel distances required by associated diversions.

12.4.33 The significant effects that result from the construction of the Proposed Scheme are shown on Map TR-03-051 (Volume 5, Traffic and Transport Map Book).

Effects arising from operation 12.5 Avoidance and mitigation measures 12.5.1 The following measures have been included as part of the design of the Proposed

Scheme and will avoid or reduce impacts on transport users:

 retaining all roads crossing the Proposed Scheme in, or very close to, their current location resulting in no diversions of traffic onto alternative routes; and  retaining all PRoW crossing the Proposed Scheme, with localised realignments or diversions.

Assessment of impacts and effects 12.5.2 The following section considers the impacts on traffic and transport and the consequential effects resulting from the operational phase of the Proposed Scheme (as described in Section 2.4 of this report).

12.5.3 The operational traffic and transport impacts within this area will arise from the realignment of PRoW.

CFA Report – Colne Valley/No7 | Traffic and transport

12.5.4 Occasional traffic may access areas of the Proposed Scheme for maintenance purposes. However, these infrequent vehicle movements will be very low and will not have a significant effect.

12.5.5 No significant effects on parking or loading will result from the operation of the Proposed Scheme in this area.

12.5.6 The effects on accident and safety risks will not be significant as there are no increases in traffic during operation.

12.5.7 It is not expected that the operation of the Proposed Scheme will require any bus route diversions and there will be no impacts on rail services in the area.

Consequently, there will be no effects on public transport users during operation of the Proposed Scheme.

12.5.8 There will be minor adverse effects on the relatively few non-motorised users as a result of increased travel distance due to permanent PRoW and road realignments at Rickmansworth 004 (bridleway and dry valley); Tilehouse Lane, DEN/3 – Shire Lane (bridleway); Old Shire Lane Circular Walk; and U34 (footpath). The length of realignments will be between 250 metres and 400 metres.

12.5.9 There will be no effects on navigable waterways within this area due to the operation of the Proposed Scheme.

12.5.10 The impacts and consequential effects of the operation of the Proposed Scheme in 2041 will be the same as described for 2026, having taken account of increased background traffic growth.

Cumulative effects 12.5.11 The assessment includes cumulative effects of planned development during operation by taking this into account within background traffic growth.

12.5.12 The assessment includes cumulative effects by taking into account transport impacts as a result of the Proposed Scheme in neighbouring areas. There will, however, be no additional traffic in this area resulting from the operation of the Proposed Scheme in neighbouring areas.

Other mitigation measures 12.5.13 No other mitigation measures during operation of the Proposed Scheme are considered necessary based on the outcome of this assessment.

Summary of likely significant residual effects 12.5.14 Permanent realignment of five PRoW, including roads, to accommodate the Proposed Scheme will result in increased travel distances, but affect relatively few nonmotorised users.

12.5.15 The significant effects that result from the Proposed Scheme in 2026 and 2041 are shown on Map TR-04-062 (Volume 5, Traffic and Transport Map Book).

13 Water resources and flood risk assessment

Introduction

13.1 13.1.1 This section provides a description of the current baseline for water resources including surface water, groundwater and the baseline conditions for flood risk. It then reports on the likely impacts and significant effects on these aspects as a result of the construction and operation of the Proposed Scheme.

13.1.2 The main environmental features of relevance to water resources and flood risk

include:

 the wide floodplain valley of the River Colne and a tributary, the Newyears Green Bourne;

 the Mid Colne Valley SSSI (see Map EC-01-011 and EC-01-012 (Volume 5, CFA7 Ecology Map Book). This SSSI consists of several lakes between the River Colne and Grand Union Canal and part of the River Colne;

 flooded gravel pits and the Grand Union Canal which both occupy parts of the valley floor;

 the Cretaceous Chalk, a Principal aquifer (see Map WR-02-007, Volume 5, Water Resources and flood risk assessment Map Book); and  licensed private and public water supply groundwater abstractions and associated source protection zones (SPZ).

13.1.3 Key environmental issues relating to water resources and flood risk include:

 permanent realignment of the River Colne and Newyears Green Bourne;

 construction of a viaduct pier in the existing River Colne and a number of piers through some of the lakes within the Mid Colne Valley, including Harefield No.

2 Lake, Savay Lake, Korda Lake and Long Pond;

 potential impacts on groundwater quality as a result of construction activities associated with tunnelling, piling and retaining walls;

 potential impacts on groundwater flow towards public water supplies (PWS) located close to the route due to the piles to be constructed in the aquifer to support the viaduct;
