THE AGENT The Agent for the proposed CTLR Project is: Sweco UK Limited 2nd Floor Quay 2 139 Fountainbridge Edinburgh, EH3 9QG www.sweco.co.uk Sweco was appointed by the Developer as the lead consultant in July 2017 to progress the proposed CTLR Project through the Local Planning Application process. Sweco has provided key consultancy support to develop the project specimen design. Sweco has provided the required technical input to the EIA and co-ordinated other specialist consultants (see Table 1.1) and have submitted the planning application, the EIAR and all supporting documents on behalf of the Developer.

Need for the Project Further information is available in Chapter 3: Project Need, Objectives and Alternatives of the EIAR.

Perth (Image 3) is the main settlement in Perth and Kinross and serves a number of rural communities and villages in Perthshire and Kinross-shire. Perth is also considered to be the ‘gateway’ to the Scottish Highlands and Islands. The city is a major strategic hub in the Scottish transport network where the principal routes connecting the central belt to North and North-East Scotland meet.

The need for the project is established through the transport strategy for the Perth and Kinross region which was informed by technical work to appraise various transport alternatives. The proposed CTLR Project will deliver improved access for vehicles and Non-Motorised Users (NMUs), which will deliver economic growth within the local area and promote sustainable travel.

Alternatives

Further information is available in Chapter 3: Project Need, Objectives and Alternatives of the EIAR.

The proposed CTLR Project has included work through the Perth Traffic and Transport Issues Scottish Transport Appraisal Guidance (PTTI STAG), Shaping Perth’s Transport Futures Strategic Environmental Assessment (SEA), DMRB Stage 1 and DMRB Stage 2 route options. The PTTI STAG identified in 2010 that predicted increases in traffic would exceed the city’s traffic capacity. The study recognised that the physical constraints for future transport network improvements include the River Tay, Kinnoull Hill and the Highland Mainline Railway. The findings of the PTTI STAG highlighted that the transport network was not able to deal with projected increases in population (and the associated vehicle increase) which were anticipated in the Council’s LDP2. The seven key problems outlined were predicted to worsen if no change was made to the existing transport network. The recommended options from the PTTI STAG were taken forward for consideration in Shaping Perth’s Transport Futures SEA. Shaping Perth’s Transport Future strategy document provided a high level compilation of the findings from the previous studies into a single document for consultation. The strategy document was presented to the Council on 10 January 2012, when it was formally adopted, and approval was given to carry forward the proposed CTLR Project to DMRB Stage 1. The transport proposals then formed part of the Council’s LDP and these have been carried forward into LDP2 (expected to be adopted on 29 November 2019). The DMRB Stage 1 assessment identified a corridor to the north of Perth should be taken forward to DMRB Stage 2. The DMRB Stage 2 Assessment was completed in 2016 which evaluated two alternative route alignments within the preferred corridor identified in the DMRB Stage 1 Assessment. The DMRB Stage 2 Assessment identified a preferred route, which was approved at a Council meeting held on 14 December 2016. A review of the CTLR alignment between the A93 and A94 was undertaken in Spring 2019 to consider an alternative alignment ( Figure 2) further to concerns raised by Scone & District Community Council (SDCC). Primarily, SDCC raised concerns relating to the road safety and air quality impacts upon the future residents of the development and requested a route to the north of the North Scone Development (H29) be considered.

Figure 2: Alternative Northern Alignment

The technical comparative assessment concluded that the alternative northern route provides no improved benefit when considered against the specific concerns regarding air quality and road safety and against all of the other assessment criteria. Overall the technical assessment favoured the current preferred route. The alignment review also consisted of a risk based assessment of the alternative northern route considering technical, financial, environmental, economic and legal risks. This assessment was undertaken in accordance with the Council’s approved Risk Management Framework. This detailed assessment of the risks associated with the consequential delay in the CTLR programme by changing the route at that stage of the project however clearly demonstrated the significant financial, legal, reputational and other consequential impacts which would be realised should the northern route be adopted. Both assessments were considered by the Council at its meeting on 19 June 2019 where the Council agreed to proceed with the current preferred route; this route is the subject of this planning application.

Project Description Further information is available in Chapter 2: Project Description of the EIAR. The proposed CTLR Project comprises eight main components, as set out below in Figure 4. Further details of the project (including the redline boundary) are illustrated in Figure 3.

Figure 3: CTLR Location

Careful consideration has been given to key environmental constraints from early in the design process for the proposed CTLR Project and this has carried on throughout. Strong collaboration between the Developer, and the Agent team has ensured that mitigation measures have been embedded in the design (i.e. the Highfield Green Bridge, the SUDs Wetland).

The proposed CTLR Project will have the following benefits:

Reduces traffic congestion in and around Perth Improves City Centre and Bridgend air quality issues Provides new transport infrastructure for all modes which enables new, planned and committed

developments for both housing and employment Enables City Centre improvements envisaged in the Perth City Plan New and improved access for communities and the wider area.

Image 4: A94 Roundabout Junction on the proposed CTLR Project (visualisation)

From its most westerly point, the proposed CTLR Project covers a section of the A9 to the north of the Inveralmond Roundabout and crosses over the Highland Mainline Railway which links Perth to Inverness. The study area is bisected at the west side by the River Tay running north to south (Figure 4). The CTLR Project crosses the River Tay (heading eastwards), passing through Mansfield Estate and to the north of Scone Palace. The new road would bisect Stormontfield Road, the A93, Highfield Plantation and then would meet the A94 at its most eastern reach. The land use surrounding the proposed CTLR Project is mixed consisting of residential properties, arable farmland, open green space, forestry, private estates, businesses and commercial properties.

ACCOMODATION WORKS Consultation with landowners and tenants is ongoing and it is normal practice for the details of accommodation works to continue beyond the EIAR process. However, agreed mitigation measures and accommodation works will be included within the construction contract. Although some specific details are unknown at this stage, it is assumed for the purposes of the residual impact assessment, that appropriate mitigation such as field and steading accesses will be provided. In addition, the accommodation works would include the installation of a temporary fishing hut to the south of the proposed River Tay Crossing Bridge. There will also be the relocation of the existing fishing hut. The relocation of the existing fishing hut is expected to reduce noise levels and permission for the permanent relocation will be sought under a separate planning application by the relevant land owner.

CONSTRUCTION It is anticipated that construction methods required for all elements of the proposed CTLR Project are likely to have environmental implications. As such, the construction phase for the project has been a key consideration in the EIA. Construction of the proposed CTLR Project is currently programmed to commence in late 2021, with the construction period expected to last until 2024. The appointed Contractor shall be responsible for preparing their own programme for the construction works which will require approval by the Developer. This programme will be required to take account of any restrictions contained in the Contract and this EIAR.

The proposed CTLR Project will require temporary works3 to enable the western pier of the River Tay Crossing Bridge to be constructed. The pier is located between the Highland Mainline Railway and the River Tay. To provide safe and sufficient access, a number of potential temporary access options have been considered (as shown in Figure 4). These options can be summarised as:

1. Option 1 – access from the south via a temporary bridge crossing of the River Almond, travelling northwards on the east side of the railway to the bridge location;

2. Option 2 – access from the west over and under the Highland Mainline Railway, travelling eastwards to the bridge location; and

3. Option 3 – access from the north via the existing Luncarty junction, travelling southwards to the bridge location.

3 Temporary works are (those) parts of the works that allow or enable construction of, protect, support or provide access to, the permanent works and which will not remain in place at the completion of the construction phase.

The EIA Process

Further information is available in Chapter 4: EIA Methodology (Approach to Assessment) of the EIAR.

An EIA of the proposed CTLR Project is required under European and Scottish legislation. The EIAR reports the findings of the EIA. The purpose of the EIA is to investigate the likely significant effects of the proposed CTLR Project on the environment. The EIA has been undertaken in line with relevant legislation and guidance. Details about likely impacts of the proposed CTLR Project can be found in the EIAR. For ease of use, the EIAR is presented across three documents as follows:

Volume 1: Non-Technical Summary (this document) Volume 2: EIAR Volume 3: Cumulative Effects Assessment

The EIA process provides an opportunity to minimise potential environment effects through design refinement. Environmental constraints and issues have been identified through consultation, extensive environmental surveys and technical assessments. The information gathered has informed decision-making throughout the design process. This has provided the opportunity to address potentially significant impacts where practicable, for example, by refinement of the proposed CTLR Project or by incorporation of measures to avoid or reduce potential adverse impacts. Impacts have been assessed by comparing the existing situation (baseline) to the expected conditions that would occur in the opening year (2023) and the design year (2038 = opening year + 15 years). In accordance with the requirements of the Town & Country Planning (Development Management Procedure) (Scotland) Regulations 2013, a Proposal of Application Notice (PAN) has been submitted to Perth & Kinross Council.

Consultation and Scoping CONSULTATION Consultation has been undertaken to:

seek feedback and comments from Statutory and Non-Statutory Consultees on environmental aspects of the proposed CTLR Project;

to ensure Statutory Consultees, other Non-Statutory bodies and the public are informed about the proposed CTLR Project and are provided an opportunity to comment;

to obtain information relevant to the baseline and to inform the environmental assessments; and to agree survey and assessment methodologies where relevant.

Over 90 meetings with Statutory, Non-Statutory and interested parties have been held since September 2017 and these have been recorded in the Consultation Diary which has been submitted with this EIAR. Two rounds of public exhibitions (Spring 2018 and August 2019) have been undertaken at a number of different locations (for more information please refer to the Pre-Application Consultation Report).

Image 6: Public Exhibition in Scone (2019)

The purpose of the two rounds of public exhibitions (Spring 2018 and August 2019) was to provide the local community with a number of opportunities to keep them updated with progress, to present them with the latest information and most importantly to give them opportunity to continue to comment on and contribute to the proposed CTLR Project and the evolving design. Feedback from the public exhibitions held in August 2019 was predominately positive:

1 impressive display materials; 2 well planned design of the CTLR; 3 priority given to active travel;

4 keen to see the road in place; and 5 environmental enhancements (particularly Highfield Green Bridge and SuDS Wetland Area).

However, there were some concerns raised, the main ones being around the traffic modelling, the project being long overdue, existing congestion at Inveralmond roundabout and traffic increases, with particular reference to HGVs, affecting communities along the A94 to the north of Scone. The Q&A documents (Appendix 4) produced after the events is available on the PTFP website (https://www.perthtransportfutures.co.uk/cross-tay-link-road/). A Public Exhibition Report (Appendix 7), summarising the events held in Spring 2018, was compiled afterwards and is also available on the PTFP website. The consultation process has informed the EIA team’s understanding of the potential environmental sensitivities associated with the area of the proposed CTLR Project and altered the design as demonstrated in Image 7 and Image 8.

Along with the public exhibitions, a significant level of consultation has been undertaken and has included the following;

Over 90 meetings with Statutory, Non-Statutory and interested parties since September 2017; Regular updates on the Council’s Social Media (Twitter etc.) as the project progressed; and Provision of a specific section on the PTFP website where regularly updated information about

the project is available.

There has also been;

Two phases of public engagement as set out above (eight separate consultation events) were organised to correspond with key project milestones including four specifically for the Pre-Application Event and these were attended by over 750 people;

Numerous public notices were placed in the press and posters advertising the events were placed in 18 different locations;

Leaflets were produced that summarised the proposals and outlined how to give feedback, noting that comments provided are not representations to the Planning Authority. All leaflets are available on the project website for the August 2019 public exhibitions and the Spring 2018 public consultation events.

At the public events, a fly-through video was shown, which outlined the proposed CTLR Project and provided an insight into what the potential future developments could look like.

There was also a swipe map available for attendees, that showed the proposed CTLR alignment and how it has changed from the DMRB Stage 2 process. The changes of alignment were predominately a result of consultation with Statutory and Non-Statutory Consultees, members of the public and key stakeholders. Early in Stage 3 a due diligence and value engineering review led to changes which helped to: balance the cut and fill; minimise the environmental impact of the design and improve constructability. The first phase of consultation then highlighted some areas of concern which resulted in further design improvements. The key changes addressed concerns as follows: Highfield Green Bridge was introduced to optimise connectivity across the CTLR; the shared cycleway offset was increased, and it was taken offline where feasible; and the A94 Roundabout was repositioned further from Newmains steading.

SCOPING The Town and Country Planning (Environmental Impact Assessment) (Scotland) Regulations 2017 make provision for a Developer (the Council’s Road and Infrastructure team) to write to a relevant competent authority (the Council’s Planning Authority) and request a formal opinion, in writing, of the information to be provided in the EIAR. This is called a Scoping Opinion. The principal aim of the EIA scoping exercise for the proposed CTLR Project was to establish the key issues to be considered as part of the EIA. This exercise has also informed the evaluation of the significance of the predicted environmental effects of the proposals and has identified key issues for the assessment. A Scoping Request was prepared by the EIA team to identify the proposed ‘scope’ and information requirements for the EIA and content of this EIAR. A formal request for a Scoping Opinion was made to the Council’s Planning Authority on the 12 September 2018. The Council’s Planning Officer provided their Scoping Opinion on 23 October 2018. This opinion has been used to inform the assessments undertaken for this EIAR.

Further information is available in Chapter 5: Consultation and Scoping of the EIAR.

Air Quality

Further information is available in Chapter 6: Air Quality of the EIAR. The proposed CTLR Project is located within Perth & Kinross Council area and has been developed to

improve air quality within the Perth AQMA. A detailed modelling assessment has been undertaken to determine the effects of air quality emissions of oxides of nitrogen (NOx), nitrogen dioxide (NO2) and fine particulate matter (including PM10 and PM2.5,) from the proposed CTLR Project on sensitive human receptors. The potential impact upon ecological receptors was scoped out of this assessment. The methodology of this assessment has been scoped with the Council’s Environmental Health Team. The main focus of the assessment is the potential impact of road traffic emissions on local air quality. It aims to assess air quality at locations where residential properties or other sensitive receptors may be affected by changes to traffic activity associated with the proposed CTLR Project. The assessment also considered the potential impact upon air quality during construction with regards to dust emissions. The risk assessment of construction phase activities concluded that dust during construction could potentially affect nearby residents. A series of mitigation measures have been recommended which aim to ensure that there will be no adverse effects due to construction dust. Accordingly, mitigation measures will be implemented as required as set out in the outline Construction Environmental Management Plan (CEMP), along with appropriate management and monitoring measures. The air quality assessment considered seven modelling scenarios for both current (2017) and future (2023 and 2038) baseline air quality, and the impact of road traffic emissions on concentrations of NO2, PM10

and PM2.5 at receptors have been predicted using atmospheric dispersion modelling using the Ricardo Energy & Environment RapidAIR® model. Annual mean concentrations of each pollutant have been modelled within the study area that matches the area included within the transport model. The assessment has predicted that changes to traffic flows when the proposed CTLR Project becomes operational will have a positive effect on annual mean NO2, PM10 and PM2.5 concentrations at the majority of locations assessed, particularly within Perth AQMA in the City Centre and Bridgend.

Cultural Heritage

Further information is available in Chapter 7: Cultural Heritage of the EIAR.

Cultural heritage includes archaeology, historic buildings/structures and historic landscapes including parks and gardens. An assessment on the direct and indirect impacts of the proposed CTLR Project on heritage assets has been undertaken, and in order to complete this Historic Environment Scotland (HES) and Perth and Kinross Heritage Trust (PKHT) were consulted. The Cultural Heritage assessment considers direct impacts on all known designated and non-designated heritage assets within the boundary of the proposed CTLR Project. A study area of 250m is used around all temporary and permanent elements of the proposed CTLR Project to understand the development of the historic environment and to create a predictive model of the probability for potential buried archaeological remains to exist. Extensive geophysical survey and trial trenching has been undertaken over the unwooded parts of the proposed CTLR Project. The potential for unknown assets across the proposed CTLR Project is low, with the exception of pre-historic assets between the eastern bank of the River Tay and Stormontfield Road, post-medieval assets between Stormontfield Road and the A93, pre-historic Roman and early medieval assets in the Blairhall area of compensatory planting and pre-historic assets in the Cairnton area of compensatory planting. In these areas the potential for assets of the specified periods is moderate. Adverse effects of moderate significance are predicted on the multivallate fort at Broxy Kennels during construction due to the demolition of this asset. However, through a programme of archaeological recording this effect can be mitigated to very slight. There are currently three options for the River Tay Crossing Bridge construction access, and this assessment has considered all three. Should Option 1 be used (temporary crossing over the River Almond), a Scheduled Monument Consent application would be required as the route travels over Bertha Roman Fort Scheduled Monument. To mitigate and reduce the adverse effects on the scheduled monument, detailed mitigation measures have been developed and agreed with HES. The predicted significant operational effects include adverse impact to the setting of parts of Scone Palace Garden and Designed Landscape (GDL) and Grassy Walls Roman Camp Scheduled Monument. In both cases the greatest effect is located within the area called Bowman’s Field as this is the area where the new road will pass through. Adverse effects of moderate significance are predicted on the setting of one non-designated heritage asset due to the severance and demolition of the asset, the multivallate fort at Broxy Kennels.

Landscape and Visual Impact Assessment

Further information is available in Chapter 8: Landscape and Visual Impact Assessment of the EIAR.

The proposed CTLR Project is located in a landscape whose character is strongly influenced by the Scone Palace GDL and the distinctive features of the River Tay and prominent wooded ridges. The landscape is predominantly rural and includes a distinct mix of policy trees and woodland, open and flowing spaces (typically managed for agriculture) and historic focal features. The landscape is enjoyed by visual receptors, such as residents, travellers and visitors, experiencing a range of views such as distant panoramas, semi-enclosed views over rolling farmland, and focused views of landmarks. Assessment of the predicted landscape and visual effects of the proposed CTLR Project has been undertaken using standard methods for Landscape and Visual Impact Assessment (LVIA). The main findings of the LVIA are that the proposed CTLR Project would result in significant adverse landscape effects in 11 Local Landscape Character Areas (LLCAs) within the study area in the first year after opening and in 9 LLCAs 15 years after opening. In addition, it would result in significant adverse visual effects on 49 visual receptors in the first year and on 35 visual receptors 15 years after opening. These significant landscape and visual effects primarily reflect the high value of the baseline conditions within the study area, as most of the proposed CTLR Project would be in or visible from the Scone Palace GDL and/or the Sidlaw Hills Special Landscape Area (SLA). The large cutting through the Bertha Park wooded knoll introduces the River Tay Crossing Bridge, which crosses over the Highland Mainline Railway and the River Tay. Consequently, adding a prominent main road, junctions and associated vehicles into open spaces within a rural landscape. The LVIA found non-significant landscape and visual effects would typically occur in places more distant from the proposed CTLR Project, where it would be partially or fully screened, and/or it would relate to the baseline characteristics. In addition to primary mitigation measures embedded within the design of the proposed CTLR Project, there is some potential for the adoption of secondary mitigation measures (such as protection of riparian trees along the river, sensitive design and detailing of lighting and extending planting where beneficial) to reduce further the predicted significant adverse landscape and visual effects, subject to future agreements.

Biodiversity

Further information is available in Chapter 9: Biodiversity of the EIAR.

There are valuable habitats and species of nature conservation importance which could be impacted by the proposed CTLR Project. The assessment on biodiversity (defined as plants and animals and the habitats in which they live) considers the potential effects of the construction and operation of the proposed CTLR Project on the following:

Important Ecological Features (IEFs); River Tay Special Area of Conservation (SAC); Ancient woodlands; Protected species including badger, beaver, otter, pine marten and red squirrel, bats, breeding

birds, freshwater fish and pearl mussel; and Habitats.

The presence of a range of IEFs within the ecological survey area has been assessed by means of desk-based assessment, detailed surveys and consultations, in accordance with the DMRB and other standard survey guidance documents. One of the key risks to biodiversity as a result of the construction of the proposed CTLR Project is from silt-laden and contaminated run-off entering the River Tay SAC from river bank-side work. Should such events occur there is potential for adverse effects to occur to the populations of Atlantic salmon, lamprey and otter for which the SAC is designated, and freshwater pearl mussel which meets the criteria for SAC designation. However, the construction works will be subject to a number of control and management measures, including construction site licensing under the Water Environment (Controlled Activities) (Scotland) Regulations 2011 (CAR Regulations). During operation, control measures including SuDS would mitigate the risk of uncontrolled polluted run-off. The clearance of vegetation (including ancient woodland habitat) during the construction of the proposed CTLR Project would result in the loss of woodland habitat and nesting, roosting, resting and foraging habitat for a range of species. The loss of mature woodland habitat will be partly offset by the provision of woodland planting, however, the loss of ground flora, soils, seed bank and structure alongside the loss of roosting habitat for bats would result in a significant residual effect. A range of mitigation measures will be implemented to reduce the adverse effects of the proposed CTLR Project on individuals and populations of notable species. Mitigation measures include:

Fencing; Culverts adapted for mammal passage; Replacement roosting habitat for bats; Provision of wetland habitat (SuDS Wetland Area) for a range of species; Provision of Highfield Green Bridge which has been designed to be suitable for both human and

animal users; and Implementation of best practice and site-specific mitigation measures during construction and

operation.

Hydrogeology and Soils

Further information is available in Chapter 10: Hydrogeology and Soils of the EIAR.

There are no designated sites, for example Sites of Special Scientific Interest or Geological Conservation Review Sites within the study area that are designated for their geological or geomorphological importance. Potential effects as a result of the proposed CTLR Project during construction include:

Accidental release, leakage or spillages of hydrocarbons, chemicals, fuel or oils from storage tanks or construction plant during construction causing contamination of groundwater;

Localised increase in alkalinity from spillages of concrete or unset cement; and Potential contamination of the water environment due to the disturbance of contamination

associated with construction works and in particular deep excavations (e.g. bridge foundations, deep utility excavations), or the mobilisation of contaminants due to groundwater pumping.

The potential operational effects stated above on hydrogeology and soils are expected to occur (or continue to occur) once the proposed CTLR Project is in operation. Mitigation measures for the construction phase will comprise standard good construction practices covered by a Construction Environmental Management Plan (CEMP) produced by the Contractor. Mitigation measures for the operational phase will be subject to detailed design. An outline CEMP (Appendix 2.2 of the EIAR)has been prepared as part of this EIA and forms part of the planning application submission. The recommended mitigation measures during the construction of the proposed CTLR Project are considered sufficient to minimise the identified potentially significant effects on sensitive receptors to a non-significant level. In summary, based on the currently available information no significant adverse residual or cumulative effects have been predicted.

Materials

Further information is available in Chapter 11: Materials of the EIAR.

The assessment of the construction and operation effects of the proposed CTLR Project with regards to the use of materials and generation of waste has been undertaken using methodology outlined in Design Manual for Roads and Bridges (DMRB), LA 110: Material assets and waste4. The effects of the proposed CTLR Project in relation to materials during operation have been scoped out given the minimal requirements for materials and generation of waste. The proposed CTLR Project will require significant volumes of imported construction materials for foundations, road construction, backfill and structures. The proposed CTLR Project also includes significant earthworks, principally from earthwork cut activities for the realignment of the A9, with material placement required for the A9 overbridge abutments and grade separated junction.

As well as the significant earthworks, the proposed CTLR Project requires construction of three box culverts (Bertha Loch Burn, Stormontfield and Broxy Burn) and three key structures (A9 overbridge, River Tay Crossing Bridge and Highfield Green Bridge) .

Current estimates suggest that all excavated materials can be re-used within the proposed CTLR Project. Maximising opportunities to stockpile and re-use suitable material within the proposed CTLR Project (such as landscaping or screening bunds) will reduce the effects from the generation of waste arisings. No off-site disposal of material from the earthworks is anticipated. Where the re-use of materials on-site is not possible, options for the re-use of materials off-site (e.g. as restoration soils) will be fully considered by the Contractor in accordance with their approved CEMP and Site Waste Management Plan (SWMP). The Contractor will develop this further when appointed and create a SWMP in consultation with the Council and the Statutory Consultees as required. The assessment has concluded that the effects upon materials as a direct result of the proposed CTLR Project is not significant, however suitable mitigation measures have been recommended in accordance with best practice and site waste management.

Noise and Vibration

Further information is available in Chapter 12: Noise and Vibration of the EIAR.

A detailed modelling assessment has been undertaken to determine the effects from changes in noise levels from the proposed CTLR Project on Noise Sensitive Receptors (NSR). There is a number of NSR, such as residential and commercial properties, within the study area that currently have little exposure to road traffic noise. The temporary noise and vibration effects of the project during construction have been considered; although these effects may be significant at times, the effects will be short term and will be mitigated, as far as reasonably practicable, through implementation of Best Practicable Means and subject to other control mechanisms administrated by The Council Planning and Environmental Health Departments (i.e. the CEMP and contractual requirements). Predictions of road traffic noise across the study area have been undertaken for scenarios with and without the CTLR, in the base year (2017), year of opening (2023) and the future assessment year (2038). The future assessment years with the proposed CTLR Project include additional trips associated with future residential developments that have been consented and are identified in the Local Development Plan (LDP). Given the interdependence between the CTLR and the residential developments, these future trips are assessed as part of the future impact of the CTLR Project. A baseline noise survey across the study area has determined existing levels of environmental noise at locations agreed in advance with the Council. These measurements have been used to contextualise the predictions of absolute levels of road traffic noise and the changes that will occur because of the proposed CTLR project. The assessment has considered whether noise barriers are required to reduce noise levels associated with the future traffic flows. This assessment has determined that a roadside bund will be included on the north side of the proposed CTLR mainline beside Newmains Steadings. The road traffic noise associated with the proposed CTLR Project is predicted to be localised with the majority of existing NSR close to existing sources of road traffic noise (A9, A93 and A94). Therefore, negligible or minor adverse impacts are predicted. Significant adverse effects are predicted at existing NSR close to the CTLR mainline where there is currently little contribution from road traffic noise and the predicted change is therefore of greater magnitude. However, absolute levels of future road traffic noise often remain less than recommended in current standards and guidance.

People and Communities

Further information is available in Chapter 13: People and Communities of the EIAR.

The People and Communities assessment considers the impacts of the proposed CTLR Project on Non-Motorised Users (NMUs), vehicle travellers, and community and private assets during both the construction and operation of the road. The assessment has considered the potential effects on journey length and amenity, driver stress, views from the road, public transport provision, private properties, community land, facilities and outdoor access and potential impacts upon severance or improved connectivity. NMU paths are scattered across the study area therefore retaining and enhancing NMU provision (where possible) has been a key consideration for the project and considered throughout the design process. The following provisions have been included:

a new 3m shared-use pedestrian/cycleway along the CTLR which would provide a connection for communities either side of the River Tay.

Highfield Green Bridge. NMU connection to the eastern bank of the River Tay. Controlled crossing facilities at all new roundabouts. Improved NMU path along the A93. Improved existing core path connecting Scone Park and Ride and Newmains Steading to the CTLR

along the A94. Park and Cycle scheme on the stopped up section of the A9.

Existing west-east journeys to the north of Perth require drivers to travel through Perth City Centre, therefore resulting in driver stress. The proposed CTLR Project will improve the connection between the communities to the west and east of the River Tay, providing some relief of existing severance caused by the river. Views for drivers travelling along the proposed CTLR Project will offer attractive open views across Scone Palace GDL and rolling countryside. Public transport infrastructure will include six new bus stops along the proposed CTLR Project; as well as an improved layby on the A9. The proposed CTLR Project will provide additional access for all users to public transport. Traffic flow reductions within the centre of Perth is predicted to reduce existing community severance between communities. The reduction in traffic flows within the centre of Perth will enable active travel improvements as a part of Phase 4 of Perth Transport Futures Project. Thereby, further improving active travel in and around Perth. Demolition is required for one property a result of the A9 realignment. No land-take is required from the curtilage or property of any other residential and commercial properties. However, some properties would experience a change in access. Highfield Plantation will be severed to the south due to the proposed CTLR Project. It’s use will therefore have an impact on the local community as a local outdoor recreational area. To mitigate these impacts, Highfield Green Bridge is proposed which will maintain connectivity into Highfield Plantation for the local community and wildlife.

Agriculture, Forestry and Sporting Interests The predominant land use along the proposed CTLR Project is agriculture with parcels of forestry and woodland. The proposed CTLR Project would result in a permanent loss of approximately 95 hectares (ha) of agricultural and forestry land, equating to a moderate adverse impact when considering the total route. Mitigation measures to reduce the impacts on agricultural businesses and sporting interests will include both temporary and permanent measures such as:

relocating access routes for farm steadings and fields; reconnection of field drainage systems; reinstatement of boundary features; provision of a temporary fishing hut to the south of the proposed River Tay Crossing Bridge; and improved access tracks.

There will also be the permanent relocation of the existing fishing hut. The relocation of the existing fishing hut is expected to reduce noise levels and permission for the permanent relocation will be sought under a separate planning application by the relevant land owner. The assessment found that with suitable mitigation in place, no farms or sporting interests would have their viability compromised by the proposed CTLR Project and residual impact would not be significant. Bertha Park wood was found to have a significant residual adverse effect as a result of the proposed CTLR Project. All other woods are expected to have a non-significant effect. Mitigation measures to reduce the impact on woodland and forestry parcels will include compensatory planting and creating new access routes.

Road Drainage and the Water Environment

Further information is available in Chapter 15: Road Drainage and the Water Environment of the EIAR.

The assessment on the Road Drainage and the Water Environment considers the surface water environment during both construction and operational phases and road drainage provision during the operation and associated potential effects to receiving watercourses. The main watercourse in the study area is the River Tay, which is a designated SAC for its populations of Atlantic salmon, lamprey species, freshwater pearl mussel and otter, as well as being a sensitive freshwater habitat. As such it is considered to be of very high sensitivity. One of the greatest risks to the water environment and aquatic ecology is silt-laden and contaminated run-off entering the River Tay SAC directly from works on the river banks, as well as the cumulative effects of in-channel works in nearby tributaries during the construction phase. However, these construction works will be subject to a number of contractual control and management measures, and in particular construction site licensing under the Controlled Activities Regulations. A flood risk assessment has been undertaken to determine the potential effects during construction and operation. Permanent residual effects on all watercourses and areas of flooding are predicted to be of negligible magnitude and Neutral significance for hydrology and flood risk. Following implementation of best practice and site specific mitigation measures during construction and operation detailed in this chapter, all residual effects are predicted to reduce to no more than minor magnitude and slight significance, and therefore not significant in the context of the EIA Regulations. In addition, a SuDS Wetland Area has been included in the design, removing the requirement for three separate outfalls to the Caravan Drain in close proximity to each other (instead the wetland feature will attenuate and treat runoff from the CTLR carriageway and outfall to the Caravan Drain from a single outfall). As well as having attenuation and treatment benefits, the SuDS Wetland Area will also provide improved amenity and visual impact as well as creating wildlife habitat. Refer to Chapter 2: Project Description for more information.

Climate This assessment has considered the effects of the proposed CTLR Project on climate (i.e. generation of ‘greenhouse gas’ emissions, referred to herein as ‘carbon’) and its resilience to climate change.

CARBON IMPACT ASSESSMENT The effect of the proposed CTLR Project on climate has been minimised through the implementation of Publicly Available Specification (PAS) 2080:2016, the world’s first specification for Carbon Management in Infrastructure. Emissions associated with the proposed CTLR Project are not anticipated to materially affect the ability of the UK or Scottish Governments to achieve their carbon reduction targets, and thus are not predicted to have a significant effect on the global climate. Nevertheless, adoption of the PAS 2080 carbon reduction process in the proposed CTLR Project is ongoing and is recommended to continue through to completion of construction to ensure that any predicted effects on the climate are fully considered and minimised where possible.

CLIMATE CHANGE RESILIENCE ASSESSMENT Using the latest available climate change projection data provided by the Met Office, UKCP18, the resilience of the proposed CTLR Project assets and environmental receptors has been assessed and no significant effects are predicted, i.e. the proposed CTLR Project and its surrounding environment have been deemed sufficiently resilient to the effects of projected climate change.

Population and Human Health

Further information is available in Chapter 17: Population and Human Health of the EIAR.

An assessment has been carried out to determine the likely significant effects upon population and health determinants associated with the proposed CTLR Project. The aim is to ensure population and human health is effectively considered in the EIA context, drawing on the results of other technical assessments and refocusing the conclusions onto health and social determinants (i.e. wellbeing, amenity, access to green space etc.). The assessment has considered the impacts that could arise during construction and when the road is built and operational. The assessment has considered both existing and future communities and drawn upon available baseline data. Potential adverse effects are predicted during the construction of the proposed CTLR Project, however mitigation and best practice will manage these appropriately. The construction phase will provide beneficial impacts to the local population through opportunities to maximise the benefits to local people and the wider communities. Phase 1 of the PTFP won numerous awards for its community benefits and social value contribution, and it is proposed to build upon the relationships already established and the successes, ensuring the proposed CTLR will contribute even more to local communities. Further information is provided in Appendix 17.3 but some examples include:

Local jobs created Work experience placements Health and Safety training Graduates and apprentices employed Engagement with pupils and students Money raised for charity Volunteering with the community Waste diverted from the landfill

Improvement in the local economy is one of the main aims of the proposed CTLR Project, as it will unlock development land as envisaged in the LDP, thereby facilitating sustainable economic growth in the Perth area. The operation of the proposed CTLR Project is predicted to have some positive and negative impacts upon population and human health however. It will connect communities, provide improved active travel routes, reduce air quality and congestion in Perth City Centre and improve access to high quality landscape areas. It will, however, result in localised noise and air quality effects and visual impacts at some sensitive receptors and increased traffic movements along the new route and on some parts of the existing road network (A93/A94 and Inveralmond Roundabout). The A9 experiences existing levels of congestion, to which it is anticipated that the proposed CTLR Project will increase. However, the predicted increase to congestion is an issue Transport Scotland is aware of. No significant adverse effects on population and human health determinants are predicted.

Summary of Effects

Further information is available in Chapter 18: Summary of Effects of the EIAR.

The residual environmental effects of the proposed Cross Tay Link Road (CTLR) Project are those likely effects following the implementation of the proposed mitigation measures. Each technical chapter of the EIAR presents a detailed consideration of the likely residual effects during the Construction and Operational Stage of the proposed CTLR Project. Operational residual effects are generally permanent in nature, whereas construction effects are often temporary nature (albeit for a period of approximately 2.5 years). For this chapter significant residual effects have been identified as those remaining at moderate (adverse/beneficial) or above. The Environmental Impact Assessment (EIA) has identified there will be residual effects during both the construction and operational phases of the proposed CTLR Project. The following significant residual adverse construction effects are predicted:

Adverse effects to landscape and visual receptors; Permanent loss of woodland and habitat; Path closures and diversions; Change to private property access; and Adverse effects to agricultural and woodland holdings due to construction compounds.

The proposed CTLR Project will however reduce congestion on the main road network particularly through Perth City Centre and Bridgend. This will provide beneficial effects to air quality through a reduction in NO2, PM10 and PM2.5 concentrations. Communities either side of the River Tay will be connected via the River Tay Crossing Bridge, and a new active travel route for existing and future communities will be provided along the southern side of the proposed CTLR Project.

Schedule of Mitigation

Further information is available in Chapter 19: Schedule of Mitigation of the EIAR.

The design of the Cross Tay Link Road (CTLR) Project has been progressed taking account of identified environmental constraints and considerations, enabling avoidance or reduction of potential environmental impacts where practicable (i.e. embedded mitigation). Mitigation measures have also been identified following the assessment of impact significance, which are considered necessary to further reduce or compensate for potential impacts. All contractual and legally binding mitigation measures are highlighted within Chapter 19 and these have also been included within the outline Construction Environmental Management Plan (CEMP) (provided in Appendix 2.3). The outline CEMP includes all the measures provided below and has been prepared and describes methods and techniques that will be employed during construction to ensure compliance with legislation, good practice. The appointed Contractor will take this outline CEMP and prepare a detailed CEMP which builds on the information laid out in this Schedule of Mitigation. This detailed CEMP will have to be approved by the Council’s Planning Authority and others.

Cumulative Environmental Assessment Cumulative effects refer to how an environmental resource/receptor may be subject to a particular type of impact from more than one development or project. The impacts from multiple developments or projects may overlap; or act in combination, at a particular location or upon a particular receptor/resource, thereby potentially leading to more significant environmental effects than if the impacts were considered in isolation. For example, two projects resulting in significant impacts upon the cultural setting of a designated asset may lead to more significant setting impacts than just one of the projects.

The Cumulative Environmental Assessment (CEA) has taken account of the potential for significant effects which may arise from the construction and operation of the proposed CTLR Project, together with other consented developments. The CEA has also considered other ‘reasonably foreseeable’ development proposals. Due to the long-term nature of the potential effects of the proposed CTLR Project (positive and negative), the assessment has considered two future years after the projects are anticipated to be completed. These assessment years are:

2023: considered representative of the opening year; and 2038: considered representative of a future assessment year.

The inter cumulative5 assessment took account of other reasonably foreseeable developments which included sites identified in relevant LDPs and key planning applications which were considered cumulatively with the proposed developments in a 2023 assessment scenario. A cumulative assessment was also undertaken for the proposals in combination with the predicted longer term (2038 future year) environmental effects from development of housing and commercial property sites set out within Perth and Kinross Council LDPs. The intra cumulative assessment considered the additive or amplified effects resulting from environmental effects on ‘shared receptors’ and also where sources of effect from different components of the project may combine to be of greater significance than when considered alone. Inter cumulative effects were identified in Chapter 2. These were with regards to loss of habitat and ancient woodland, increases in noise at specific receptors, overall loss of agricultural land and increases in traffic across the local and regional road network. It was also with regards to improvements in active travel, connectivity and the likely contribution from community benefits that the proposed CTLR Project and the future developments could generate. These effects would be expected with regards to the level of future development proposed within and around Perth and particularly those sites within a close proximity to the proposed CTLR Project. Intra effects were identified during construction and operation on the following receptor groups; Luncarty, Sherrifton Cottage, Balboughty, New Mains, Coupar Angus, Balbeggie, Bridgend, Perth (City Centre), Broxy Kennels, Scone GDL, River Tay SAC, Highfield Plantation, Bertha Park & Woods and Denmarkfield. These will be mitigated against as far as possible, but some will remain due to the nature of the impact (loss of ancient woodland, loss of habitat, etc).
