1 PHASE 2 SECTION 73 AMENDMENTS ENVIRONMENTAL STATEMENT NON-TECHNICAL SUMMARY DECEMBER 2013

2 Battersea Power Station Phase 2 Amendment ES Non-Technical Summary Background This document provides a non-technical summary of an Environmental Statement (ES) which accompanies an application made by Battersea Project Phase 2 Company Limited (the Applicant ) to amend the existing planning permission for the comprehensive redevelopment of the Grade II* listed Battersea Power Station and surrounding land (hereafter referred to as the Site). The Site extends to a total area of 20.9 hectares (51.7 acres) of land, although the development area of the Site extends to 15.8 hectares (39.1 acres) and includes: Battersea Power Station (hereafter referred to as the Power Station ), 188 Kirtling Street; 28 Kirtling Street; 88 Kirtling Street; and 2 Battersea Park Road. The Site is an important strategic location within the Vauxhall, Nine Elms and Battersea Opportunity Area. This Opportunity Area comprises 195 hectares of land located south of the River Thames between Lambeth Bridge and Chelsea Bridge and is identified in the London Plan for the delivery of new homes, jobs and transport infrastructure. The location of the Site is presented in Figure 1. In 2011, the former owner of the Site, Real Estate Opportunities (REO (Powerstation) Limited, secured planning permission and listed building consent for repairs, alterations (including partial demolitions) and extensions to the Grade II* listed Battersea Power Station, as well as the wider redevelopment of land and buildings at the Site. The permission for this masterplan is subsequently referred to as the 2011 Masterplan Permission. Following this approval, the current owner acquired the Site in September Environmental Impact Assessment (EIA) is a process required under UK law for certain development projects which assesses the possible impacts that the project may have on the environment. The purpose of the EIA is to ensure that decision makers are fully aware of the environmental impacts of a project before making a decision on whether to grant planning permission. The 2011 Masterplan Permission scheme was subject to an EIA undertaken by URS and the findings of this EIA were presented in an ES in The amendments to the 2011 Masterplan Permission were supported by updates to the ES prepared in 2009 (hereafter referred to the 2013 ES ). Following the grant of the 2011 Masterplan Permission, the ownership of the Site changed and the new owners secured approval for the detailed design of the first phase of the redevelopment (known as Phase 1 ). In December 2013, planning permission was granted for a series of amendments to the 2011 Masterplan Permission under a provision (Section 73) of The Town and Country Planning Act (1990) (subsequently referred to as the 2013 Masterplan Permission ), which allows the conditions attached to the planning permission to be varied. The 2013 Masterplan Permission, together with certain minor variations and the detailed design approvals for Phase 1 is referred to hereafter as the Consented Scheme. The Consented Scheme would deliver a sustainable new town centre in Battersea, which would provide a high quality of life for future occupants and residents and be a comfortable, secure and inclusive place in which to live, work and play. The Grade II* listed Power Station is in urgent need of longterm repair and the Consented Scheme provides this opportunity. The Consented Scheme would deliver much needed regeneration and socio-economic enhancement and makes the most sustainable and efficient use of space in London by encouraging growth in an area of need and opportunity.

3 SITE LOCATION Battersea Power Station Phase 2 Amendment ES: Figure 1: Site Location

4 In 2013, the Applicant appointed Wilkinson Eyre Architects to develop and refine the approved detailed design proposals for the Power Station (located within Phase 2 of the Development). This forms part of the Site s wider redevelopment which comprises the surrounding routes and spaces on the riverside. The extent of Phase 2 in the context of the Consented Scheme and the other phases and development zones are shown on Figure 2. This ES has been submitted to the London Borough of Wandsworth (LBW) together with a suite of documents to accompany a further planning application under Section 73 of The Town and Country Planning Act (1990), made by the Applicant; the purpose of which is to make amendments to the 2013 Masterplan Permission to reflect Wilkinson Eyre Architect's revised design for the Power Station. As the Power Station is a listed building, an application for a new listed building consent has also been submitted to the LBW, who are required to consult with English Heritage amongst others in deciding whether to approve the proposals. The amendment application (hereafter referred to as the Phase 2 Section 73 Amendments ) once approved would lead to the grant of a new planning permission for the Site as a whole. Collectively, the Consented Scheme as amended by the Phase 2 Section 73 Amendments is referred to as the Development. The Consented Scheme has already been subject to EIA; the findings of which were reported in the 2013 ES. However, since planning permission is now sought for the Development (in its revised form with the Phase 2 Section 73 Amendments) it is necessary to carry out a further EIA and present the results in a new ES. EIA Methodology The Applicant commissioned Waterman Energy, Environment & Design Ltd to prepare a new ES to allow LBW, stakeholders and the public to fully understand the impacts of the Development as a whole, to ensure transparency of decision making and to avoid the EIA becoming a paper-trail of documents. The ES is therefore a standalone document and does not refer back to the 2013 ES submitted for the Site prior to this document. Scoping forms the first stage of the EIA process and it is through this that LBW was consulted on those environmental aspects that may be significantly impacted by the Development, and, as such, should be included in the EIA. The EIA has been undertaken largely on the basis of the scope of the EIA undertaken for the Consented Scheme. A Scoping Report, setting out the general approach to the EIA for the Phase 2 Section 73 Amendment ES and the potential impacts to be addressed in the EIA was prepared and submitted to LBW in October An EIA Scoping Opinion was received from LBW on 2 December 2013 which agreed that the scope would be as per the previous 2013 ES, although the following environmental topics included in the 2013 ES could be scoped out: Planning Policy Context analysis of the planning policy context of the Site is provided in the Planning Statement which accompanies the application; Daylight, Sunlight and Overshadowing (Internal) this is considered to be a design consideration rather than environmental impact and the conditions within the Development are therefore considered in a standalone Internal Daylight, Sunlight and Overshadowing Report which accompanies the planning application; Aviation impacts on aviation issues were assessed and found to be not significant in the 2013 ES and were therefore not considered further in this Phase 2 Amendment ES; and Electronic Interference - impacts on these issues were assessed in the 2013 ES and found to be not significant and were Page 2

6 therefore not considered further in this Phase 2 Amendment ES. In addition to the EIA Scoping Report, consultation relating directly to the EIA and design considerations has been undertaken with a number of bodies including the Greater London Authority, English Heritage, the Environment Agency, Thames Water, Port of London Authority, Network Rail, Transport for London, 20 th Century Society, SAVE England s Heritage, Western Riverside Waste Authority, The Battersea Society, Battersea Power Station Community Forum and local residents, owners and occupiers. The EIA has been based primarily on: Planning application drawings and parameter plans (such as boundary plans, details of layout, details of land use, details of access and circulation and scale parameters); A Development Specification document which defines and describes the principal components of the Development; and Application drawings for the new listed building consent application. A three-dimensional model of the Development has been used as a tool for testing for certain environmental issues (daylight, sunlight and overshadowing, wind, townscape, conservation and visual impacts). This has been derived from the Consented Scheme parameter plans, incorporating the approved detailed design for Phase 1 and the Phase 2 Section 73 Amendments. Some of the other key assumptions with regard to the basis of the EIA include: Policy and Guidance: the Phase 2 Section 73 Amendments have been considered against current planning policy and guidance, therefore each ES chapter includes a brief summary of current relevant documents; Baseline Conditions: information on the existing environmental conditions presented in the 2013 ES has been updated as necessary. In some cases it has been considered appropriate to rely on baseline data presented in the 2013 ES (and where that is the case those data have been re-presented in this ES); Impact Assessment: impacts of the Site Preparation and Construction phase and Development once completed and operational are considered in the ES for each technical topic. These impacts are based on the Consented Scheme incorporating the Phase 2 Section 73 Amendments. This is because the EIA Regulations require the approved development as changed or extended to be assessed, rather than just the amendments themselves. The EIA therefore does not assess the impacts of Phase 2 alone; nor does it provide a detailed comparative study between the impacts of the Consented Scheme and the Phase 2 Section 73 Amendments. General commentary is, however, provided at the end of each ES chapter to indicate the key differences in environmental impacts; and Cumulative Assessment - a number of consented and other development schemes likely to come forward ( cumulative schemes ) have been considered within the cumulative assessment. Most of these schemes were considered in the 2013 ES, although the list of cumulative schemes has been updated. For ease of reading, each technical chapter of the Phase 2 Amendment ES adopts the same structure, broadly in line with the 2013 ES. The Phase 2 Amendment ES addresses the likely impact of the Development on its neighbours, local environment, local and regional economy and the wider area. Beneficial and adverse, short and long-term (temporary and permanent), direct and indirect and cumulative impacts have been considered. The ES identifies and describes the relevant mitigation measures to be adopted and 'residual' impacts are evaluated with reference to definitive standards, accepted criteria and legislation where Page 3

7 available. Where it has not been possible to quantify impacts, qualitative assessments have been carried out, based on expert knowledge and professional judgement. In order to ensure a consistent approach throughout the Phase 2 Amendment ES, the following terminology has been used to define potential and residual impacts (assuming mitigation is in place): Adverse - detrimental or negative impacts to an environmental/socio-economic resource or receptor; Negligible - imperceptible impacts to an environmental/socio-economic resource or receptor; and Beneficial - advantageous or positive impact to an environmental /socioeconomic resource or receptor. Where adverse or beneficial impacts have been identified these have been assessed against the following scale: Minor; Moderate; or Major. In reaching the final design for the Development, the design team has engaged in extensive analysis of the Site followed by a period of design evolution and development with specialist consultants. Site Description and Setting The Site comprises four main areas: Battersea Power Station, 188 Kirtling Street. This is the main part of the Site and is bound by the River Thames to north, Battersea Park Road to the south, Grosvenor Bridge and railway land to the west, Kirtling Street to the south-east and the Thames Water Battersea Works and the Western Riverside Waste Transfer Station to the north-east. This part of the Site includes the following buildings: o Grade II* listed Power Station and the Grade II listed Battersea Water Pumping Station. Both buildings are vacant; o A number of structures within the curtilage of the Power Station. These include part of the river wall, a jetty, cranes and associated structures. These are currently unused; o A series of former waterworks buildings in the south-east of the Site. These are currently used by the Applicant for office and storage purposes; o Two linked temporary modern exhibition buildings; o A redundant district heating facility that has been constructed in the north-east of the Site and currently used for storage; o A series of temporary/mobile offices and shed type structures; and o A temporary pavilion building and riverside park in the north of the Site between the Power Station and the River Thames. 28 Kirtling Street. This part of the Site is bound by Cringle Street to the north, Kirtling Street to the west and office buildings to the south and east. This part of the Site is currently used by London Duck Tours as a depot and maintenance compound; 88 Kirtling Street. This part of the Site is bound by the River Thames to the north, Kirtling Street to the south, an aggregates plant and working wharf to the west and St. James Riverlight development to the east; and 2 Battersea Park Road. This part of the Site is bound by office buildings to the north, east and west and by Battersea Park Road to the south. The Site is now cleared and vacant but was previously occupied by a petrol filling station. Photographs of the existing Site are provided as Figure 3. The Northern Line Extension (NLE) forms part of wider plans to regenerate the Vauxhall, Nine Elms and Battersea area. An application was made under The Transport and Works Act (1992) in April 2013 by Transport for London and this was accompanied by an ES. A decision is anticipated on the NLE in the Page 4

9 summer The 2013 Masterplan Permission included illustrative material in relation to the proposed NLE which would have a station within the southern part of the Site on Battersea Park Road. Alternatives In line with the EIA Regulations, the Phase 2 Amendment ES provides a description of the main alternatives to the Development considered by the Applicant. The EIA Regulations only require the ES to state the main alternatives studied by the Applicant, although for completeness, amendments and alternatives between the grant of the 2011 Masterplan Permission and the Applicant s involvement have been considered. Design alternatives which pre-date the 2011 Masterplan Permission have not been considered in the Phase 2 Amendment ES as these were not alternatives considered by the current Applicant. The alternatives considered in the Phase 2 Amendment ES are summarised below. Do Nothing Scenario This Do Nothing scenario relates to the Consented Scheme not proceeding. Construction of Phase 1 commenced in October 2013 and therefore work on the Consented Scheme is already underway and this is not considered by the Applicant as a realistic alternative. The Consented Scheme would deliver the regeneration of a strategic brownfield Site in addition to repairing the Grade II* listed Power Station. Furthermore, the Consented Scheme would act as a catalyst for regeneration and socio-economic enhancement fulfilling the policy aspirations of both the London Plan and the Vauxhall, Nine Elms and Battersea Opportunity Area. This would not be realised if the Consented Scheme did not proceed beyond Phase 1. Alternatives to the 2011 Masterplan Permission A series of amendments have been made to the 2011 Masterplan Permission for different reasons. The most significant resulted from health and safety restrictions on land uses associated with the nearby gas holders being lifted. Following the lifting of this restriction, residential land use was moved from the less suitable location around the safeguarded wharves to the north east of the Site to Phase 1. This position offered environmental improvements for future residents in terms of air quality and noise, as well as providing better natural light conditions and views towards the Power Station. It was also considered by the Applicant that the 2011 Masterplan Permission needed to be altered to provide a more attractive shopping offer. Accordingly, the Applicant also made amendments in May 2013 to increase the amount of retail floorspace in the High Street (within Phase 3). The provision of hotel spaces within the Site was also amended. The Applicant secured approval for a series of amendments to the 2011 Masterplan Permission in December 2013 (i.e. the 2013 Masterplan Permission) as their preferred alternative to the 2011 Masterplan Permission. Consented Scheme without the Section 73 Amendments This relates to implementing the Consented Scheme (as shown in Figure 4) rather than the Consented Scheme with the Phase 2 Section 73 Amendments in place (i.e. the Development assessed within the Phase 2 Amendment ES). Rafael Vinoly Architects developed the 2011 Masterplan proposals for the comprehensive redevelopment of the Site. This provided a solution to a complex listed building (Battersea Power Station) that historically proved a challenge to redevelop. The appointment of Wilkinson Eyre Architects by the Applicant was a key step in evolving and finessing the Rafael Vinoly vision for the Power Station. The principal reasons behind the Applicant selecting to make the proposed Phase 2 Section 73 Amendments to the Consented Scheme relate to improving the quality and usability of the Power Station, rather than in direct response to environmental considerations.

11 in full with the Consented Scheme, however, would not result in the design improvement benefits outlined in the Phase 2 Amendment ES and the Design and Access Statement which accompanies the planning application and hence this is not considered a preferable option for the Applicant. Table 1 presents a summary of the proposed Amendments to the Consented Scheme. Design Alternatives (Phase 2 Section 73 Amendments) The Phase 2 Section 73 Amendments have been the subject of extensive discussions with LBW, English Heritage and other key stakeholders. A number of slightly different designs were considered by Wilkinson Eyre Architects and the Applicant. However, these are not regarded as main alternatives under the meaning of the EIA Regulations and therefore are not considered further in this Phase 2 Amendment ES. Through the Phase 2 Section 73 Amendments the Applicant is seeking to amend the detailed design of the Power Station, together with amendments to some planning conditions relating to access and circulation plans, the energy strategy, car parking and residential units. In addition to the above amendments the application seeks permission to vary planning conditions whereby the Applicant can apply to occupy non-residential elements of the Power Station prior to the opening of the NLE station on the Site. A summary of the main changes being submitted for approval is provided in Table 1. Note that all figures are provided as footprint areas in metres squared (m 2 ) and these relate to Gross External Area (GEA) which is a standard measurement for planning applications, unless otherwise stated.

Minor increase in height to all three residential extensions of the Power Station as follows: o Annex A: increase of 0.76m; o Annex B: increase of 1.31m; and o Boiler House: increase of 0.925m. Setting back of the Boiler House extension from the parapet walls; and New articulations around proposed courtyards. A new central atrium within the office space in place of eight circular atria; Increase in circulation space of 5,091m 2 to 20,402m 2 ; and Provision of a full height void space behind the southern façade of the Boiler House. Increase in residential units within the Power Station by 70 to 248 units, although there would be no overall increase to the number of residential units across the Site; Creation of an additional floor of residential accommodation in Annex A; and Revised residential unit mix with greater proportion of studio and one bedroom apartments. Changes to the pedestrian access strategy, including providing a centralised office entrance to allow residential access through the washtowers. Changes to the window fenestration on the Boiler House and Annex A and B of the Power Station. Provision of a lift access within the north west chimney of the Power Station to provide a high level viewing platform with public access. Revised energy and sustainability strategies. Use of natural gas within the Energy Centre as the main fuel type and ongoing development of the Energy Centre with consideration of bio-fuel usage*. Amendments to the external landscaping, including a new sunken plaza in front of the southern Power Station entrance and new piazzas to the east and west of the Annexes of the Power Station. Minor amendments to the proposed basement access and arrangements to reflect new access and circulation plans across the Site. Increase of depth of parts of the basement beneath the Power Station of up Page 7

13 Topic Phase 2 Section 73 Amendments Site- Wide - Car and cycle parking spaces to approximately 13m from the Consented Scheme to accommodate plant rooms and service corridors. Slight reduction in basement depth proposed in Phase 3 by approximately 3m. Increase in car parking space provision in Phase 2 to 799 (an increase in 145 spaces), therefore increasing the total for the Development to 2,920 Decrease in cycle spaces to 962 (a decrease of 96) therefore decreasing the total for the Development to 6,423. The liquid biomass / biofuels currently being investigated for use in the Combined Heat and Power Plant are certified renewable fuels derived from organic * matter produced entirely from post manufacture waste products or residue. They are not palm oil or any other first generation bio-fuels, contain no fossil fuels or additives, and have been confirmed as not contributing to land degradation. Page 8

14 The Development In terms of layout, the Development would involve the redevelopment of land and buildings, including alterations to the Power Station, the demolition of other existing buildings on the Site and construction of new buildings for a mix of uses. The Development comprises a number of buildings as illustrated in Figure 5), with the tallest element some 64m Above Ordnance Datum (AOD), in addition to a newly landscaped public areas. Once fully complete, the Development would provide a total of 903,577m2 Gross Internal Area and 925,763m2 Gross External Area. The uses within the Site area presented below for each land use. Maximum floorspace figures are provided as Gross External Areas unless otherwise stated: 3,444 residential units (includes 248 units in the Power Station); 30,345m 2 hotel (3 hotels are proposed a 40-bed boutique hotel in the Power Station) 20,567m 2 serviced apartments (assumed as 254 units); 150,773m 2 of office; 64,859m 2 of retail (excluding food and drink); 4,631m 2 of retail/retail (food and drink); 4,631m 2 of food and drink; 21,853m 2 of culture, community and leisure; 5,722m 2 of event / conference; 245m 2 of riverbus ticket office and passenger facility; 184,220m 2 of parking, servicing and plant storage 6,650m 2 of Energy Centre; and 20,402m 2 of Power Station circulation space. The land uses would be split amongst eight development zones. The eight development zones are spatial divisions made within the seven phases of Development, one or more of which would be constructed during each phase of construction. The location of these development zones is displayed within Figure 2 and summarised below: Development Zone RS-1 (Phase 1) RS-1 is the area in the north west corner of the Site. It is situated with the railway line and service road along its western boundary, and the Power Station to the east. The development zone is approximately triangular in plan and encloses a courtyard from which access to the apartments is gained. RS-1 (Phase 1) has been granted detailed planning approval and construction commenced in October The RS-1 development zone comprises of two buildings RS-1A and RS-1B. Both buildings have been granted approval for mixed use, predominantly residential and would have a maximum height in RS-1A of m AOD to respect and complement the massing and place of the adjacent Power Station. The RS-1 Development Zone comprises a mixture of uses including food and beverage, retail, business, community / culture / leisure, open courtyard and internal circulation and residential uses. Power Station (Phase 2) The Power Station lies at the heart of the Site and is Grade II* listed and therefore will be the central focus of the Development. The Consented Scheme proposals for the Power Station have been refined by Wilkinson Eyre Architects and the refinements form part of the Phase 2 Section 73 Amendments. The majority of the changes are to uses within the building with minimal changes to the Consented Scheme proposed externally. The proposals comprise mixed uses including retail, office, residential, hotel, cultural and leisure, event and conference, food and beverage uses and associated public space. The proposals include car parking and plant at basement level. Above this, the Power Station would include three levels of retail use spanning across the Boiler House and Turbine Halls A and B. In Annexes A and B, residential accommodation would be provided within the existing fabric of the building and Page 9

16 within extensions above of the existing Power Station to accommodate seven residential floors within Annex A and eight residential floors within Annex B. Above the retail space in the Boiler House, a triple height event/leisure level would feature a multi-event space, a boutique cinema, café and restaurant and boutique hotel. Above the event space, would be six storeys of office space and an additional two levels of residential properties on the roof. An auditorium would be created on Level 2 to provide a flexible entertainment venue. It is assumed the capacity of this event venue (the Boiler House venue ) would be approximately 2,000. Control Room A would be maintained and restored to form a venue for a range of uses, including a restaurant. An Energy Centre would be located to the north of the Power Station within the basement and lower basement level beneath Power Station Park. The Energy Centre comprises a gas-fired CHP and back-up gas boilers to deliver a district energy network for the Development. Curtilage Structures (cranes, jetty and river wall), Fuel Import Facility and Passenger Pier (Phase 3) The jetty and associated cranes and river wall form part of the curtilage to the Grade II* listed Power Station. The Consented Scheme includes listed building consent for the proposed works which form part of the Development. No amendments to the Consented Scheme have been proposed in relation to these features in the Phase 2 Section 73 Amendment application. For the fuel import facility, it is envisaged that fuel deliveries would run on an average of one delivery per week during Site operation. The fuel facility would consist of the following elements fuel import berth, access and dredging. The function of the passenger pier is to provide public access from the Site to the riverboat services. The facility would consist of a floating pontoon, access brows, pontoon ramp, a terminal building, access platform, a bankseat, access bridge, barge protection dolphin, existing cranes and temporary passenger pontoon. The temporary passenger pontoon would be relocated to the eastern end of the existing pontoon to allow greater distance from Grosvenor Bridge, although this amendment would be sought under another application to amend the listed building consent for the main jetty. Development Zone O-1 (Phase 3) Development Zone O-1 is located along the south western corner of the Site adjacent to the railway lines and the service road on the western boundary of the Site. The O-1 Development Zone comprises predominantly residential accommodation above retail units on the ground and lower ground floors. At the northern end of the block, a hotel would be located overlooking Battersea Power Station and the Town Square. This hotel would complement the High Street and Power Station land uses. The building also contains a large frontage onto the High Street and therefore has an important level of retail usage at the lower ground and ground floor levels. It is proposed that retail and some food and drink uses would be present along the High Street on ground and lower ground floor levels. Development Zone RS-4 (Phase 3) RS-4 within Phase 3 is the block to the south east of the Power Station. It is primarily residential on upper floors with retail and food and beverage outlets at ground and lower ground level. The ground floor retail facing onto the High Street also includes community space with a library fronting on to The Prospect. Development Zone RS-5 (Phase 4) RS-5 within Phase 4 is a similar block to RS-4. This block would also be of two typologies; the terrace type façade and the curved façade. The ground floor activity along Pump House Lane would comprise small-scale office uses rather than retail use and the larger part of the ground floor would be taken up with a multiplex cinema whilst the southern front Page 10

17 would comprise food and beverage outlets. To the eastern end of RS-5, the final two subblocks would comprise a hotel aimed towards a business operator. Development Zone RS-6 (Phase 5) Development Zone RS-6 is located on the eastern edge of the Site, adjacent to Battersea Park Road (to the east), RS-2 to the west across Kirtling Street, RS-5 to the south across Pump House Lane and existing offices to the north. The land use is predominantly affordable housing with additional provision for community uses. Development Zone RS-2 (Phase 6) Development Zone RS-2 is located to the north east of the Power Station building, bordering Kirtling Street on the eastern boundary and to the south and west of Cringle Street. The RS-2 block lies directly to the west of the Waste Transfer Station (WTS) and to the south of the CEMEX aggregates plant. The land use of RS-2 is split primarily between residential along the western side facing into the Power Station and the River Thames, and office use along Cringle Street and adjacent to the wharves. One block of serviced apartments is located alongside the WTS. Development Zone RS-WF (Phase 7) This zone is located in the north eastern corner of the Site, at the northernmost area of Kirtling Street. The zone borders the River Thames to the north, CEMEX aggregates plant to the west. The land use of RS-WF is primarily residential on upper floors, with food and beverage uses provided at ground floor. Due to the proximity to the CEMEX aggregates plant and the proposed Thames Tideway Tunnel, the apartments proposed along the western side of RS-WF would be single-sided to face inward towards a central courtyard. This should reduce nuisance from noise and dust. Access The main road access in and out of the Site would be via three main junctions on Battersea Park Road as follows: A new traffic signal controlled junction on Battersea Park Road opposite Savona Street; The junction between Battersea Park Road / Kirtling Street / New Convent Garden Market Access; and The Cringle Street/Battersea Park Road junction. Other transport initiatives that have been agreed as part of the Consented Scheme include: Local junction improvements designed to accommodate the additional traffic generated by the Development; Facilitating the bus improvements that are currently envisaged in the Vauxhall, Nine Elms and Battersea Opportunity Area (VNEB OA) Planning Framework; High quality pedestrian and cycle networks, linking the development to the surrounding areas, and alternative modes of transport; and River bus services from the Jetty. The Public Transport Accessibility Levels for the Site range from poor to good. It is acknowledged by the LBW, the landowners and developers within the VNEB OA that only a major new transport infrastructure facility, i.e. the NLE, would achieve the significant increase in the levels of public transport accessibility necessary to provide sufficient extra capacity to serve the Development and other major schemes planned within the area. The new tube line, the NLE station on the Site and associated works do not form part of this planning application but would come forward in due course. The application includes some illustrative information in relation to the proposed tube extension, and shows a zone for tube-related works within the Site, which has been discussed with London Underground Limited. The design of works within that zone would be developed in full Page 11

18 consultation with London Underground over the forthcoming months as part of the decision making process relating to this infrastructure. The Development would provide a maximum of 2,920 car parking spaces and 6,423 cycle spaces. All parking and servicing will generally occur at below ground and basement levels. Some cycle parking will be provided at ground level. Service bays will also be provided for commercial vehicles together with parking for coaches (10 spaces) and motorcycles (200 spaces). Cycle parking would also be provided at the NLE station (100 spaces). The inter-connected public, communal and private space within the Development will form a network that will create a new, public riverside setting for the Power Station (as illustrated in Figure 6), provide for the amenity needs of residents, workers and visitors, enhance the wider public realm and stitch the Development into the surrounding urban grain. The Development will include substantial areas of open space including 59,986m 2 of public realm, 39,307m 2 of private and communal roof gardens and 14,057m 2 of residential courtyards. Key areas of new public and private realm include: The Power Station Park located between the Power Station and the River Thames which will also provide access to the Jetty; The Circle - the function of the Circle will be to move people around the Power Station from the Town Square on the south side, to the Power Station Park on the north side, and to gain access to the various buildings arranged around the Power Station. The Circle will contain a body of water known as The Halo, which will act as a setting for the Power Station; The Halo - the Halo comprises an elliptical reflecting pool around the Power Station, located within The Circle. This pool forms the setting for the listed building and is an important component of the Masterplan; The Town Square - the Town Square is the space at the northern end of the High Street as it meets the Power Station. It will be traversed in the east-west direction by the Circle, which will surround the Power Station; Rooftop Gardens - the Power Station features three roof garden spaces, on Annex A, Annex B and above the main atrium space providing private amenity space for the occupants of the Power Station; Courtyards within Development Zones RS1, RS2, RS4 and RS5, courtyards will be provided for occupants; The Fountain Square - the Fountain Square is the area at the end of Pump House Lane, where it meets the Circle. It will be less of a set piece than the Town Square, and will benefit from a significant dynamic view of the front and side of the Power Station, as well as views down the Prospect; and The Prospect this is the central route into the Site from the south. It will create connections to Thessaly Road and Savona Street. The location of these features within the Development is shown on Figure 5. A central Energy Centre containing a Combined Heat and Power (CHP) plant will be provided within a new basement plant room beneath the Power Station Park. Site-wide district heating, cooling and power networks will be provided within the Development. The district heating system serving the Site will be designed with the ability to export or import from the Pimlico district heating system as well as the proposed VNEB OA district heating network. The CHP plant will initially utilise natural gas but with the flexibility to incorporate waste derived fuel (e.g. biogas) or biofuels should this become viable in the future. The liquid biomass / biofuels currently being investigated for use in the CHP are certified renewable fuels derived from organic matter and produced entirely from post manufacture waste products or residue. They are not palm oil or any other first generation bio-fuels, contain no fossil fuels or additives, and have been confirmed as not contributing Page 12

20 to land degradation. The preferred transport option for fuel delivery to the Site is via barge to a fuel import berth located at the western end of the existing jetty (north of the Power Station). Site Preparation and Construction The construction of the Development would be undertaken in seven phases over a 12-year period (October 2013 through to end 2025), as illustrated in Figure 2. Whilst the phasing programme is indicative, the phasing is represented by a programme considered to be reasonable and achievable. The phasing strategy for the Development would be reviewed over time to take account of market conditions, economic drivers and development aspirations, together with the NLE and adjacent Thames Tideway Tunnel, should these be granted permission. However, the technical information presented in the Phase 2 Amendment ES which forms the basis of the Site preparation and construction impact assessment does present the worst case scenario, particularly in relation to aspects such as the number of residential units completed per year, Heavy Goods Vehicle (HGV) movements, construction workers and Site logistics. Relatively little demolition work is proposed other than the following on Site structures: The existing site offices and temporary exhibition facilities; The Grade II listed Battersea Water Pumping Station and Tippler House; A redundant district heating facility; and The existing commercial premises at 88 Kirtling Street. Materials from demolition arisings would be considered for use in blinding, mass fill and hardcore. Before demolition commences, an appraisal of maximising recycling / reusing materials from demolition would be carried out. Measures would be put in place to minimise the quantity of materials used and to maximise the amount of demolished materials that are recycled within the development itself. In addition, the Applicant would continue to look at sourcing materials locally to reduce transportation to site. Excavated soil / material would be generated through construction and excavation of the basement. Significant volumes of material would also be generated from construction of the NLE station boxes and underground tunnels. It is likely however that the majority of the material would be transported off site, either for disposal to a suitable disposal facility or to be used as gained material at a suitable site. The construction of the NLE station box and underground tunnels do not form part of this planning application. The existing jetty would be upgraded and retained for use as a walkway and passenger pier for riverside water taxis in the Development. It would also be considered for spoil removal by barge over the Site preparation and construction phase. The Applicant has consulted with the Port of London Authority regarding this proposal and would develop a detailed spoil removal strategy in collaboration with them. Tower cranes would be used throughout the construction phases. The Power Station chimneys which are currently in very poor condition would be removed and reconstructed as part of the Development. Once the southwest chimney has been dismantled and reconstructed (to a level of 25m above the wash tower) the remaining three will be dismantled and rebuilt at the same time. Site access and egress arrangements would vary as the construction phases progress. No road closures are planned at this stage. If the requirement for any temporary road closures and/or diversions occurs this would be discussed and agreed with LBW. All technical Chapters of the Phase 2 Amendment ES have assessed potential Site preparation and construction phase impacts. In accordance with planning conditions of the 2013 Masterplan Permission, a Construction Management Plan (CMP) has been prepared. Carillion have been appointed as the Principal Contractor for Phase 1 and a Principal Contractor would be appointed by the Page 13

21 Applicant to develop and implement a CMP for the remaining phases of the Development and the Site as a whole. The CMP would include mitigation and compliance with the LBW s Code of Practice Control of Pollution & Noise from Demolition & Construction Sites and/or Considerate Contractors Scheme would be achieved. The commitments made within this Phase 2 Amendment ES would be incorporated into a CMP, which would include roles and responsibilities, detail on control measures and activities to be undertaken to minimise environmental impact, and monitoring and record-keeping requirements. A CMP has been prepared for Phase 1, Phase 2 and Site wide. Further CMPs would be prepared for each phase of the Development. The CMP would provide a method of managing the site preparation and construction works. The CMP would outline methods for liaison with the general public, surrounding residents and the LBW, hours of work, methods to deal with complaints, and outline management practices to control noise, vibration and dust, traffic and access, waste, water resources and archaeology ensuring a high level of control throughout the Site preparation and construction phase. Any proposed working outside standard hours (08:00 18:00 hours weekdays; and 08:00 13:00 hours Saturday) would be subject to approval from the LBW. A key aspect of the successful management of the project would be the maintenance of good relations with site neighbours. The project team is already engaged in consultation with a broad range of stakeholders and this would continue through the Site preparation and construction phases of the project. The commitments made within the CMP would also be incorporated into an Environmental Management Plan (EMP), which would include roles and responsibilities, detail on control measures and activities to be undertaken to minimise environmental impact, monitoring and record-keeping requirements. EMPs have already been prepared for Phase 1, Phase 2 and the Site as a whole. Socio-Economics A socio-economic assessment has been undertaken using a wide range of information sources. These sources included planning policies, guidance and standards, population Census data. The area surrounding the Site is a historically deprived area and the two Wards closest to the Site, Queenstown and Latchmere, have some of the highest unemployment rates and lowest qualifications levels in the Borough. Government statistics classify these neighbourhoods as severely deprived in the dimensions of employment, education, training and skills development. There are 12 primary schools within 1 mile walking distance of the Site, although data from 2013 indicates that there was a total deficit of 154 places for these schools. There are no Local Parks or Open Spaces within 400m of the Site and thus there is a deficiency at these levels. Battersea Park is however a Metropolitan Open Space, and is located within 400m of the Site. The Development would have a number of beneficial impacts on the surrounding neighbourhoods. It is estimated that the Development would generate in the region of 20,914 construction job years on Site over the 12 year construction programme. In addition, an average annual spend of approximately 1 million is anticipated from total demolition and construction workers, totalling 12 million over the full programme. The provision of up to 3,444 residential homes as part of the Development would significantly contribute to the target for new housing in LBW, accounting for over three times the Borough s annual target. 15% of the dwellings would be affordable and of the total dwellings 27% are suitable for families. A total of 866 and 248 new homes would be delivered with Phases 1 and 2 respectively, by Based on the provision of 3,444 homes it is estimated that the Development would have a resident population of 6,916. Of this population it is estimated that 752 children would live within the Development. The Applicant has already committed to financial Page 14

22 contributions towards expanding or improving education provision in the Borough. This would help mitigate any impact the Development would have, particularly in view of the current limited capacity of nursery / pre-school and primary education facilities near the Site. Financial contributions have also already been agreed for the 2013 Masterplan Permission towards expanding or improving health care provision in the Borough. In addition, a new healthcare facility would be provided within the Development. This would help mitigate any impact the demand from the Development would have on healthcare. As such, the impact of the Development on local health care facilities would be negligible. The Development would inevitably generate additional employment through new commercial land uses that would occupy the Site including office, retail, community and leisure floorspace. Such land uses have the potential to create up to 10,298 additional on- Site full time equivalent jobs. The provision of substantial employment opportunities within an area of high unemployment would represent a moderate beneficial impact. The retail floorspace created within the Development represents a significant opportunity within Wandsworth and indeed south of the river, to provide a retail and leisure destination that can realistically compete with bigger shopping destinations north of the river whilst also ensuring the existing retail centres in the Borough are not adversely affected. The new residential population and employees on the Site have the potential to contribute 67.6 million annually to the Greater London area which represents a moderate beneficial impact. The Development would provide a number of public open spaces, including the Power Station Park (local park) offering a variety of opportunities for play and recreation, and a range of play spaces for children on-site near to the new homes. This represents a minor beneficial impact. The Development s mix of uses would mean there would be a new resident population as well as employees and visitors to the Site. The proposed mix and layout of land uses and publically accessible spaces would encourage activity and natural surveillance within the Site at all times throughout the day. This would reduce the opportunity for crime and improving perceptions of safety. The Development would include pedestrian routes through the Site which would open up the Site, improving access and permeability. This would help to ensure a safe environment for pedestrians. Comparison with the Consented Scheme The potential impacts associated with construction employment have remained as reported in the 2013 ES, although there has been a slight change in employment estimates. An increase in the proposed floorspace of hotel, retail, food & drink, cultural & community uses, together with a decrease in office, event & conference and change to the residential unit mix within the Power Station itself has resulted in changes to the estimated employment levels and population within the Development itself compared to the Consented Scheme. However, the significance of the impacts associated with employment and the new population has largely remained as reported in the 2013 ES. Changes to potential impacts identified between the Development and the Consented Scheme relate to education and healthcare facilities. Owing to changes to updated data on local primary school capacity, an adverse impact of the Development on primary schools is predicted although this would be offset through financial contributions from the Applicant. Similarly, an increase in population associated with the Development compared to the Consented Scheme is likely to increase pressures on healthcare facilities, although again Applicant has already committed to expanding or improving healthcare facilities within the Borough which offsets this impact. Page 15

23 Transportation and Access The Phase 2 Amendment ES provides an assessment of the transport related impacts of the Development, in relation to construction traffic, changes to highway traffic volumes, flows and capacity, public transport and capacity as well as pedestrians and cyclists. The assessment is presented in an Addendum to the Transport Assessment, the scope of which was agreed with Transport for London and LBW. There are several major roads in proximity to the Site including Battersea Park Road (A3205) and Queenstown Road (A3216). For the purposes of the assessment of traffic impacts, 2008 was taken as the baseline year for the assessment as analysis of traffic data from 2013 confirmed that traffic had not changed significantly. This approach was agreed in discussions with Transport for London and LBW. The closest residential properties are those located to the south of Battersea Park Road and to the south of the Site. Battersea Park Station is situated south of the Grosvenor Railway Bridge over the River Thames and is approximately 10 minutes walk from the Site. It is one stop from Victoria Station, which is served by the Victoria, Circle and District Underground lines. Battersea Park Station is also one stop from Clapham Junction and lies at the junction of lines leading to South London with local routes to Brixton, Denmark Hill and London Bridge. Queenstown Road Station is on the Windsor lines into Waterloo (via Vauxhall). The station is located on Queenstown Road, which is 8 minutes walk from the southwest corner of the Site. In addition, there are four existing bus services currently operating on Battersea Park Road and Queenstown Road. The NLE would provide a minimum of 15 trains per hour from a new London Underground station on the Northern Line within the Site to Kennington via a new station at Nine Elms and on to Central London. The station box would be located within the southern part of the Site along Battersea Park Road. The specific purpose of the NLE is to support growth in the VNEB OA with the Site being fundamental to supporting the use of the NLE. The NLE is therefore considered to be part of the future baseline for the purpose of the assessment of traffic impacts as it is considered to be critical to the delivery of the Development and the two proposals are interdependent. The Development has been assessed against relevant criteria for all modes of transport and for the construction and operational phases. Even at the peak of construction vehicle movements (Phase 2 Autumn 2014) construction traffic would account for less than 2.5% of existing traffic flows on Battersea Park Road, as such traffic on surrounding roads would not be adversely affected. A travel plan to promote the use of public transport to construction workers would be developed and updated as necessary for each construction phase of the Development. Construction traffic and activities would be carefully managed through the CMP and travel plan to mitigate impacts on the local road network, this includes a commitment to review the use the River Thames for spoil removal where feasible. Considering the implementation of these management measures the residual impact of construction traffic is considered to be minor adverse. The Development would facilitate safe and convenient access by all modes of transport, including cars, taxis, service vehicles, buses, pedestrians and cyclists. A total of 2,920 car parking spaces (of which 10% would be for disabled use) would be provided for the Development. All junctions within the vicinity of the Development would operate within capacity in the peak hours however journey times would become slower. A range of highway improvements have therefore been agreed together with measures as part of a Travel Plan to encourage residents and visitors to use public transport. As such the impact on the highway network would only be minor adverse. As a result of the Development passenger numbers on local bus services would increase Page 16

24 but proposed financial and infrastructure contributions to bus services to result in higher frequencies and / or new services would increase bus capacity on services to / from the Site. There would therefore be no adverse impacts on bus services from the extra passengers. The NLE is considered to be part of the future baseline assumptions used in traffic modelling as it is interlinked with the Development. Through the existing financial agreements for the 2013 Masterplan Permission the Applicant has committed to the funding of an initial 14 million contribution associated with the NLE and an additional 211 million towards infrastructure, a minimum of 72.2% of this would be for contributions to the NLE. The NLE would provide a significant increase in London Underground capacity for the area immediately surrounding the Site and the new Northern Line station would mean that the residual impact of the Development is considered to be minor adverse. The new underground station would have sufficient capacity to cater for the Development trips. The Development would provide a new pedestrian and cycle friendly route from the riverside adjacent to Battersea Park to Battersea Park Road through the centre of the Site as well as other pedestrian routes and 6,423 cycle parking spaces. The provision of cycle parking is in line with the London Plan standards. Overall the Development is considered to give rise to a moderate beneficial impact on pedestrians and cyclists. Comparison with the Consented Scheme Compared to the Consented Scheme, the Development would increase car parking spaces by 145 spaces from 2,775 to 2,920 car parking spaces. A small decrease of 96 cycle spaces is also proposed, reducing the number of cycle spaces from 6,519 in the Consented Scheme to 6,423. Small changes are also sought to vehicular access to, and movement, within the basement. Whilst updated construction traffic data shows higher traffic volumes on both Battersea Park Road and Cringle Street compared to the construction traffic data used for 2013 ES, the potential impacts identified on the local road capacity and road users remains as previously reported in the 2013 ES. Similarly, once the Development is completed and operational, additional traffic predicted as a result of the Development would not result in any significant increase in impacts when compared with the impacts previously assessed for the Consented Scheme. The overall impacts and conclusions of the Development therefore remain unchanged from the Consented Scheme, as reported within the 2013 ES. Wind Wind tunnel testing was undertaken to establish the likely wind environment of the Development and the resulting potential impacts on pedestrian comfort for particular desired pedestrian uses at ground, courtyard and at roof level. The three-dimensional model (see Figure 7) of the Development used for the wind tunnel modelling comprised the buildings for Phase 1 and Phase 2 in detail and the maximum extent of buildings within Phases 3 to 7 as defined by the Consented Scheme. Currently, the likely wind environment on the Site is expected to be suitable, or better than, leisure walking during the windiest season. During the summer season, where the wind environment of the Site would generally be calmer, conditions are expected to be suitable for standing or sitting uses, with the exception of one location to the south east of the Power Station, which would be suitable for leisure walking. As construction of the Development commences and progresses, the local wind conditions on and immediately surrounding the Site would adjust from those reported for the existing Site conditions to those reported for the Development, once completed and operational. During Site preparation and construction works on the Site, the wind environment would temporarily change, and depending on the location, would result in both Page 17

25 Battersea Power Station Phase 2 Amendment ES: Figure 7: Model of Development Used for Wind Tunnel Testing

26 adverse and beneficial wind conditions in terms of pedestrian comfort. Once the Development is complete all ground level locations tested in the wind tunnel, show that the likely pedestrian environment would be suitable for a combination of leisure walking, standing / entrance use and / or sitting, during the windiest season. During the summer season, the predicted wind conditions at ground level would largely be suitable for standing / entrance use and / or sitting. This would result in the likely wind conditions being suitable, or better than, the desired use and have a positive impact on pedestrian comfort. The likely wind environment within proposed amenity areas within the Development is expected to be largely suitable for the desired use, with the exception of the courtyard of Phase 4 and the rooftop of the Power Station, where the conditions are expected to be windier, resulting in adverse impacts on pedestrian comfort. However, with suitable planting and screening, the wind environment of these areas is expected to be suitable for the desired use. Comparison with the Consented Scheme The wind tunnel testing has shown that the predicted wind environment of the Development is similar to that of the Consented Scheme and that the Phase 2 Section 73 amendments has not resulted in significant changes to the wind environment. Consequently, the potential wind impacts on the pedestrian environment have not changed between the Consented Scheme and the Development, as assessed within this Phase 2 Section 73 ES. Daylight, Sunlight and Overshadowing Changes in the massing (that is, the general shape of the building), layout and height of buildings can result in changes in daylight and sunlight availability at the existing buildings adjacent to the Site, and can also cause overshadowing of surrounding open spaces. Similarly, the design of new buildings can influence the amount of daylight and sunlight that future occupiers enjoy. The ES presents an assessment of the potential impact of the Development in respect of daylight and sunlight availability to, and overshadowing of, neighbouring residential buildings and amenity areas. Many of the residential properties around the Site enjoy high levels of daylight in the existing situation which are more akin to daylight levels for low rise suburban environment than a central London location. It is therefore inevitable the redevelopment of the Site would entail reductions in daylight to the surrounding properties. No significant changes have occurred on the Site since the daylight, sunlight and overshadowing assessment was undertaken for the ES that accompanies the Consented Scheme. However, owing to the industry guidance (published by the Building Research Establishment) in 2011, analysis of the baseline conditions of the Site was updated in line with these guidelines so that a direct comparison could be made between the results of the baseline conditions of the Site and the Development. The assessment principally focuses on the potential daylight, sunlight and overshadowing impacts of the Development compared to the existing conditions of the Site. The potential impacts of the Development on residential properties are only assessed as they have the highest requirement for natural light compared to other uses such as commercial. Amenity spaces were also assessed with regard to overshadowing. Since the Consented Scheme for the Site, was considered acceptable in terms of daylight, sunlight and overshadowing, a comparative analysis was also undertaken between the Consented Scheme and the Development. The assessment relies on specialist computer software applied to three-dimensional models of the existing Site and the Development. The three-dimensional model of the Development comprise the buildings for Phase 1 and Phase 2 in detail and the maximum extent of buildings within Phases 3 to 7 as defined by the Consented Scheme. This represents the Page 18

27 worst case scenario for daylight, sunlight and overshadowing. The level of impact in relation to daylight and sunlight to the surrounding properties would vary throughout the demolition and construction phase, depending on the level of obstruction caused. However, it would almost certainly be less than the completed Development as the extent of permanent massing increases over time. Any temporary accommodation or equipment such as cranes would only have a minimal and temporary impact on the daylight and sunlight levels to the surrounding properties. In relation to daylight, the analysis shows 393 out of 817 of the residential rooms (48% of the total) would meet the BRE Guidelines in relation to Vertical Sky Component, which is a measure of the potential for good daylighting with the Development in place. This is a reasonable level of compliance given the open nature of the Site. The No-Sky Line analysis (a measure of the levels of daylight received in a room) shows 90% of the habitable rooms in the surrounding properties (736 out of 817) would meet the industry guidelines with the Development in place. This represents a very high level of compliance for such a large scheme on an open site. The overall impact to daylight on the surrounding residential properties is considered to be minor adverse. All of the residential properties assessed surrounding the Development received adequate levels of sunlight, and as a result, the Development is not expected to lead to significant impacts in relation to sunlight. With the Development in place, temporary shadowing of proposed amenity areas within the Development would most likely be experienced during early morning in spring and summer and throughout much of the day during the winter months resulting in adverse impacts on such areas. Similarly, permanent overshadowing of proposed amenity areas within the Development is predicted to be greater than recommended in widely accepted guidelines published by the British Research Establishment resulting in adverse impacts. However, in the summer, when proposed amenity areas are mostly likely to be used, levels of overshadowing are expected to be compliant with the industry guidelines. In addition, no area along the River Thames would be in permanent overshadow. In terms of transient overshadowing, given that the overshadowing would be constantly moving around the Site no area would be left in shade for a significant amount of time. Therefore, the residual effect of the Proposed Development in terms of transient overshadowing is considered to be Minor Adverse. Comparison with the Consented Scheme: Amendments to the Consented Scheme have resulted in minor changes to the height and massing of the Power Station within Phase 2 of the Development, which could result in changes to daylight, sunlight and overshadowing assessment presented in the 2013 ES. A comparison was therefore undertaken as part of the daylight, sunlight and overshadowing assessment within the Phase 2 Amendment ES to establish the daylight and sunlight availability predicted at surrounding residential properties. Overall, the Development is predicted to result in a similar level of impacts on daylight and sunlight availability predicted at surrounding residential properties when compared to the Consented Scheme, which was found to be acceptable terms of daylight, sunlight and overshadowing by the LBW. This reflects the minor changes made to the height and massing of the Development. The findings of the potential impacts of overshadowing remain unchanged from that reported in the 2013 ES. Light Pollution and Solar Glare The Phase 2 Amendment ES presents an assessment of the potential impact of the Development in respect of light pollution and solar glare to residential buildings (surrounding the Site and within the Development itself) and other sensitive areas including vehicle drivers on surrounding roads. Page 19

28 The assessment has been carried out in accordance with guidelines produced by the Institution of Lighting Engineers, which is standard practice. To assess the impacts, a three-dimensional model of the Development was placed in the context of the surrounding buildings which were modelled from survey information, Ordnance Survey information and Site photographs. The model was based on the detailed Phase 1 and Phase 2 schemes and the approved maximum building envelopes for Phases 3 to 7. Light pollution can be defined as any light emitting from artificial sources into spaces where this light would be unwanted. However, the results of the modelling for the light pollution assessment have shown that the levels of light pollution from the Development would not be significant during the Site preparation and construction works and once the Development is completed. At each phase of the Development, a lighting scheme would be developed to minimise light pollution and would be agreed with the LBW. The assessment of solar glare of the Development once completed and operational has been undertaken at specific viewpoints around the Site where solar glare may cause distraction to those travelling around the Development. Instances of solar glare from the buildings within the Development resulting in adverse impacts on drivers are predicted at a number of locations surrounding the Development, most notably east and west along Battersea Park Road, north-west along Savona Street and Kirtling Street and northeast along Battersea Park Road and Kirtling Street. However, instances of solar glare as a result adverse impacts would be limited to specific days and times of the year. Where possible, non-reflective materials would be used within the design of the buildings to minimise instances of solar glare surrounding the Development. Comparison with the Consented Scheme No amendments have been made to the Consented Scheme that would affect the light pollution and solar glare assessment presented within this Phase 2 Amendment ES. Consequently, the findings of the light pollution and solar glare assessment remain unchanged from the 2013 ES. Archaeology In terms of heritage designations the Site does not contain any Scheduled Ancient Monuments, Historic Battlefields, Historic Wrecks, Conservation Areas or Parks and Gardens. The Site does, however, contain the Grade II* listed Power Station and the Grade II listed former Battersea Water Pumping Station, and it lies within an Archaeological Priority Area as designated by LBW. From a comprehensive review of a wide range of datasets, including significant quantities of desk based and field work undertaken at the Site to date, it is concluded that the Site has the potential to contain below ground heritage assets (archaeological remains) dating to the prehistoric, Post Medieval and Modern periods. However, the Site has experienced significant amounts of disturbance over the years from Development in particular due to construction of a Waterworks, followed by railway sidings and Battersea Power Station in the early-mid twentieth century. As such, impacts upon this resource are anticipated to have been severe to date as a result of several phases of historic development across the Site. The impact of the Development, in particular the excavation of basements across the majority of the Site, has been anticipated to be such that further archaeological work has been set out to mitigate against the impacts. These measures include archaeological survey works, archaeological survey of the River Thames foreshore and ongoing monitoring on Site. With these in place the residual impact on archaeological features would be negligible. These measures have already been agreed with LBW and would be implemented at the site preparation and construction stage of each phase of the Development. Such measures have already been implemented for Phase 1. Page 20

29 Comparison with the Consented Scheme The principal amendment sought from the Consented Scheme that would affect the findings of the archaeology assessment, as reported in the 2013 ES, relate to changes to the depth of the proposed basement. In summary, the basement beneath the Power Station would be extended in places by approximately 3m to 13m to accommodate plant and service corridors resulting in additional areas of excavations compared to the Consented Scheme. The basement depth would be extended slightly to the south of the Power Station. However, the impacts on archaeology (if present) and therefore the mitigation required remain unchanged from those reported in the 2013 ES. Built Heritage The built heritage assessment comprised a detailed area by area approach, outlining the direct and indirect impacts of the Development on the features of built heritage value within the Site. In particular, it considers the likely impacts of the demolition, partial demolition, alteration and extension of listed buildings. It also considers the impact of the Development as a whole on the immediate setting of these heritage features. The assessment was undertaken in accordance with relevant best practice and was informed by a Heritage Impact Assessment which accompanies the application for listed building consent. Features of heritage value beyond the Site are considered in the Townscape, Conservation and Visual Impact Assessment. Built heritage features or assets contained within the Site include the Grade II* listed Power Station, the structures on the riverside which are curtilage listed due to their proximity to and relationship with the Power Station (namely the jetty, two river wall cranes used to unload coal from boats, and the river wall) and the Grade II listed Battersea Water Pumping Station. There are no other statutorily protected buildings on the Site. The Site is not located within a Conservation Area. The Grade II* listed Power Station and the Grade II listed Pumping Station are buildings that are on English Heritage s Buildings at Risk Register. The Power Station in particular includes some historic fixtures and interiors, which have not been generally accessible for over twenty-five years. Various schemes for conversion of the Power Station and development of the Site have not been delivered, largely due to a lack of viability. The Development seeks to remedy this by developing the Site as a mixed use scheme that would be properly linked to key infrastructure. The Applicant also seeks to restore the Power Station and introduce uses into it that would allow its significant spaces and artefacts to be restored and made accessible. It also would see some alterations to the external fabric as well as significant conservation works which would enable the inclusion of these new uses and make the building more functionally flexible. The structural condition of the four Power Station chimneys is such that they need to be replaced on a like for like basis. Their replacement would ensure the original design intention of the building would be preserved. The Phase 2 Section 73 Amendments include a viewing lift for visitors in the north-west chimney, ventilation through the north-west chimney and access to residential apartments through wash tower cores. These works will result in the loss of the original historic fabric although this would be offset by the impact of structurally sound replicas being constructed. The restoration and re-use of the jetty as a passenger pier would ensure its long-term use and would act as a permanent reminder of the relationship between the River Thames and the Power Station building. The Grade II listed Pumping Station would be removed to facilitate redevelopment of the Site and the restoration of the more important heritage asset; the Grade II* listed Power Station. The principle of the demolition of this building was established through the 2011 Listed Building Consent and the 2011 and 2013 Masterplan Permissions. A package of Page 21

30 measures, including salvage of notable items and building recording has therefore been agreed with LBW and English Heritage. The impact would however remain as moderate / large adverse. The listed buildings and their setting would be subject to change during the Site preparation and construction works, although these minor adverse impacts would only be temporary and would be managed through best practice measures. The design process for the Development as a whole, including the restoration of the Power Station building and the introduction of new buildings and site layout, has given special consideration to the Site s considerable recognised heritage value. As such, the architectural design incorporates measures to minimise the impact on the features of heritage value as far as possible. A Heritage Impact Assessment provides a detailed assessment of the impact of the Development on each element of the Grade II* Power Station. A summary of these impacts on the features of most value (high and very high significance) is provided below. Reference is made to the historic fabric which refers to the historic parts of the building and introduced elements, meaning new components to the Power Station: Chimneys: o Historic fabric: slight beneficial; o Introduced elements: very large beneficial; Control Room A: o Historic fabric: moderate - large beneficial; o Introduced elements: slight beneficial; North elevation: o Historic fabric: moderate: slight beneficial; o Introduced elements: moderate: slight adverse; South elevation: o Historic fabric: moderate - slight beneficial; o Introduced elements: moderate - slight adverse; Control Room B: o Historic fabric: slight beneficial introduced elements: slight beneficial; Turbine Hall A: o Historic fabric: moderate / large beneficial; o Introduced elements: moderate / slight beneficial; Directors lobby and stairs: o Historic fabric - moderate slight beneficial Introduced elements: moderate - large beneficial The present setting of the Power Station will be altered by the construction of a new neighbourhood which would enable refurbishment of the Grade II* listed Power Station, a historic building on English Heritage s At Risk Register. This enabling development includes the Town Square against the south elevation and flanking residential and office development (Phases 1 and 3). Enabling development has been designed in scale to be inferior to the existing chimney heights and the detailed design of Phase 1 already has planning approval and was considered to be appropriate by LBW and English Heritage in terms of its scale and quality. The scale and layout of other Phases of the Development have also already been accepted and are not amended by the Phase 2 Section 73 Amendments. The re-use of the area as high-density residential with associated facilities will not in itself adversely affect the setting of the Power Station, but the Development will constrain certain views of the Power Station across the Site from the south and along the Thames. However, this slight adverse impact is mitigated by the overall gain of restoring and enabling the long-term re-use of the Power Station. This slight adverse impact would also be offset by the public realm and landscape provided by the Development, including the Power Station Park, Town Square and Halo as identified above which provide a distinctive setting to the Grade II* listed building and Page 22

31 would improve the immediate visual setting of the Power Station and improve public access. Once complete the Development would: Enable the building to be employed in efficient and well serviced ways that would help secure its long-term viability; and Result in a significant enhancement of the communal significance of the Site through the increase in accessibility and public access. Comparison with the Consented Scheme The Development includes a number of design changes to the Power Station itself compared to the Consented Scheme. Most notably, the Development includes external changes to the fabric of the Power Station; including a minor increase to the height of the residential units and setting back the Boiler House extension form the outer walls. In addition, changes are sought to some of the windows to include double panes and increase the length of the windows at lower levels to increase daylight and sunlight availability within the proposed residential units. A new lift is also proposed within the north-west chimney to provide a high level viewing platform with public access. Within Town Square at ground level to the south of the Power Station, the ground level would be lowered to create a sheltered area. The approach taken to the current assessment differs slightly to the 2013 ES therefore a direct comparison of the impacts is difficult, for example the 2013 ES did not consider the impact on individual components of the building including the north and south elevations or Control Room B. The impacts on the heritage features within the Site therefore differ from the conclusions of the 2013 ES as they did not previously take into account the overall benefit of having the building returned to viable and sustainable use and in the process removing the building from the Heritage at Risk Register. Overall, the Phase 2 Section 73 Amendments reflects positive heritage gains across the board above and beyond that achieved by the consented scheme. It is therefore considered that the proposed works will secure the optimum viable use of the Site, while retaining, for the most part, the respective heritage values implicit in the Power Station s historic fabric and key features. Moreover, far wider public access will be available to a significant portion of the Power Station than has ever been possible during the history of the building. Ground Conditions The ES contains an assessment of the ground conditions and contamination potential at the Site. The potential impacts of the Development have been assessed through a desktop study of the baseline conditions, including a review of existing ground contamination and geotechnical reports relevant to the Site and associated surrounding areas. An adverse or beneficial impact in respect of ground contamination relies on a (contamination) source, pathway and receptor being present. Mitigation measures have been outlined, where necessary. The site geology consists of Alluvium (northern part of Site only) underlain by River Terrace Gravels, London Clay, Lambeth Group, Thanet Sands and Upper Chalk deposits. The Site has a history of mixed-use and industrial land uses and a number of contaminants are known to be present on Site. During construction, key potential impacts to human health and controlled waters include: Health impacts to construction workers through direct contact, dermal uptake, vapour inhalation and soil ingestion; Health impacts to adjacent site users and the public from inhalation/ingestion of dust; Degradation of shallow and deep groundwater and the River Thames from increased leaching and mobilisation of contaminants during earthworks; and Degradation of groundwater from fuel/oil /chemical spills during earthworks. Page 23

32 Standard, mitigation measures including the provision of adequate personal protective equipment and the adoption of safe working practices, stockpile management procedures, dust suppression and temporary drainage measures managed through the CMP and EMP would ensure that site preparation and construction impacts are of negligible significance. Once the Development is complete, in order to avoid, reduce and minimise any significant adverse impacts on the ground conditions across the Site, mitigation controls have been considered from the beginning of the detailed design phase. This has enabled mitigation to be embedded in the design and therefore minimise the need for active controls during occupation. Key potential operational impacts to human health and the environment include: Health impacts to future site users and maintenance workers from direct contact, soil ingestion, and ground gas accumulation/migration; Corrosion/damage of building materials and services; Degradation of groundwater (Secondary A aquifer) and the River Thames via fuel spills in car parking areas; and Degradation of groundwater (Principal aquifer) via the creation of preferential pathways during piling. Mitigation measures to be implemented comprise the use of gas protection measures in the Site buildings, implementation of clean service trenches, the storage of all fuels and oils in accordance with current regulatory and industry best practice, installation of an interceptor/surface water drainage system in new car parking areas, usage of appropriate building materials and the completion of a Foundation Works Risk Assessment. Following mitigation, impacts from the completed Development are assessed to be negligible. Comparison with the Consented Scheme The principal changes proposed as part of the Development relates to changes to the depth of the proposed basement. The basement beneath the Power Station would be extended in places by approximately 3m to 13m compared to the Consented Scheme resulting in additional areas of excavations. The basement depth would also be extended to the south, north and north-east of the Power Station. Nevertheless, the potential impacts and mitigation measures of the Development on ground conditions and contamination remain largely similar to that reported in the 2013 ES. Owing to a change in the sensitivity rating of the adjacent residents to the Development with regard to fire, explosion and/or gas inhalation from ground gas, there has been a change in the potential impacts identified within the 2013 ES, although with mitigation measures in place, the residual impacts would remain unchanged. Additional mitigation measures such as the appropriate handling and storage of fuels and chemicals during Site preparation and construction works are set out in the Phase 2 Amendment ES to minimise the risk of pollution to the River Thames and underlying groundwater. Water Resources, Drainage and Flood Risk A desk-based study of water resources, drainage and flood risk was undertaken to establish the potential impacts of the Development on water use, foul water capacity, surface water drainage and flood risk on, and adjacent to the Site. As part of this study, a Flood Risk Assessment and Drainage Strategy were prepared for the Power Station itself. Consultation was also undertaken with the Environment Agency to agree on mitigation measures for flood defence along the River Thames, including the raising the height of the river wall. The River Thames is located within the northern part of the Site and shallow groundwater is present beneath the Site which flows into the River Thames. The surface water runoff of the Site is currently drained to public combined sewerage system. The main flood risk to the Site relates to the potential for Page 24

33 storm surges from the River Thames. However, the Site is currently protected from the Thames Barrier and a flood defence wall. During Site preparation and construction works, the main potential impact is expected to result from surface water runoff to, and disturbance of sediments within, the River Thames, which would have a temporary adverse impact on the water quality of the River Thames. However, during the works, any contaminated soils would be removed in line with the requirements of the Environment Agency, which would likely have a beneficial impact on the quality of the River Thames. Water would be used throughout the Site preparation and construction works, although consumption would be monitored and opportunities to would be explored to minimise use. Once the Development is completed and operational, disturbance to the sediments of the River Thames is not expected to be significant. Similarly, demand as a result of a new population within the Development in relation to water consumption and foul water drainage is not expected to be significant. It is proposed the surface water runoff would drain directly into the River Thames. However, surface water drainage from the Development would be reduced compared to the existing conditions on the Site through the inclusion of underground tanks, soakways (backfilled excavations) and green and brown roofs within the Development which would result in significant benefits to the drainage system. An increase in the height of the river wall, as agreed with the Environment Agency, would reduce the flood risk to the Site. Comparison with the Consented Scheme During the Site preparation and construction works, the temporary jetty would be located from the west of the existing jetty, as proposed as part of the Consented Scheme, to the eastern end of the pontoon. This was in response to discussions with the Port of London Authority to avoid the risk of river taxis within the vicinity of the Grosvenor rail bridge and to reduce the need of dredging of the River Thames. As a result, there would be no requirement for dredging or piling within the River Thames during the construction of the temporary jetty. The proposed drainage of surface water from Phase 2 of the Development has been amended from the Consented Scheme so that surface water runoff would be drained through an upgraded existing screening chamber rather using a number of new outfalls in the river wall, thus limiting the extent of works required on the river wall structure. All new surface water drainage would be provided by separate systems where cross-contamination of foul and surface water drainage would not possible. However, for both the Site preparation and construction works, together with the Development, once completed and operational, the potential impacts and the findings of the water resources, drainage and flood risk remain as reported in the 2013 ES. Air Quality This Chapter details the impacts on air quality of the Development, both during Site preparation and construction and once complete and operational. Baseline air quality monitoring was undertaken at the Site in 2008 and Site visits and monitoring were also undertaken to assess the potential for dust and odour emission from the adjacent Waste Transfer Station and CEMEX aggregates plant at Cringle Dock. Air quality monitoring for nitrogen dioxide was also undertaken at the Site to establish the air quality conditions in Receptors potentially sensitive to changes in local air quality include existing residential locations and schools, and proposed new residential locations as part of the Development. The impacts of emissions from road traffic from the Development have been modelled for 2012 (the baseline year) and the completed Development (2025). A number of locations have been selected within and around the Site at which modelled ground level concentrations of each pollutant Page 25

34 have been calculated - both for the baseline scenario (2012) and for 2025, with and without the Development in place. Air quality at all identified receptors in 2012 exceeded objective levels of nitrogen dioxide set by the Government without the Development. There would be a notable improvement to the local air quality between the present-day and 2025 due to the introduction of newer cleaner vehicles to the fleet, and gradual removal of older more polluting vehicles. Emissions from construction plant and HGVs would be minimised through measures set out in the CMP and EMPs. In the context of the existing pollution background levels, and given the construction schedule is phased over 12 years, with mitigation in place the likely impact from construction vehicles would be minor adverse beyond 10m from the Site boundary; negligible at the nearest existing sensitive receptors; and minor adverse within the Development. Dust from demolition and construction is expected to only represent a nuisance to receptors in immediate proximity to the construction Site. In accordance with best practice, construction dust would be controlled through the application of a series of measures as set out in the CMP and EMPs. In terms of impacts from construction road traffic, the assessment assumes a worst case that all deliveries to and from the Site and all spoil is removed from the Site by road. The use of barges instead of HGVs throughout the site preparation and construction phase, and sourcing of cement from the adjacent CEMEX aggregates plant, would reduce the number of HGV trips necessary, which would lead to reductions in emissions due to road-traffic vehicles. However as a worst case the likely residual impact would remain negligible to minor adverse. Computer modelling of nitrogen dioxide from road traffic associated with the completed Development confirms there would be a negligible air quality impact at all modelled locations, other than at one location (school, 245m north of Grosvenor Road) where a minor adverse impact was identified for nitrogen dioxide. A number of measures to encourage non-car travel would be implemented through the Travel Plan for the Development, which could further reduce predicted impacts on air quality. The modelling results for particulate matter from road traffic results showed that concentrations the impact with the Development in place would be negligible. The overall significance of introducing residential uses to the Site, taking into account the background pollutant levels is considered to be negligible to at worst minor adverse. For the Energy Centre, the 2013 ES concluded that there was a potential for major adverse impacts. Mitigation measures were therefore proposed to reduce this impact. However, modelling presented in this ES shows that the impacts of the Energy Centre would be at worst of minor adverse significance (at the School receptor mentioned above ), or negligible (at all other sensitive receptors considered), due to lower nitrogen oxide emissions associated with the use of natural gas, instead of bio-fuel (as proposed in the 2013 ES). The land occupied by Cringle Dock (CEMEX aggregates plant and the Waste Transfer Station) is designated as a Safeguarded Wharf by relevant planning policy and legislation. It is therefore acknowledged that Cringle Dock is protected for cargo-handling uses and freight-related purposes associated with the River Thames and that development either within or close to the boundary of the Safeguarded Wharf should not preclude the Wharf being used today and also in the longterm future. The adjacent Waste Transfer Station and CEMEX aggregates plant at Cringle Dock have the potential to cause nuisance dust and odour complaints to occupants of the Development. A building ventilation strategy has however, developed in consultation with LBW to reduce the risk of nuisance dust and odour issues arising. The Applicant would seek to engage in further discussions with the adjacent operators of Cringle dock on the existing dust and odour control mechanisms in place at the Waste Page 26

35 Transfer Station and potential future improvements. Comparison with the Consented Scheme With regard to air quality, the principal change from the Consented Scheme relates to a change in the fuel source of the Energy Centre in Phase 2 from bio-fuel to natural gas, together with a change to the characteristics of stack such as temperature and velocity. Consequently, the nitrogen oxide emissions predicted from the Energy Centre would be significantly lower than that reported within the 2013 ES. Whilst there has been a predicted increase in traffic related emissions to air, owing to the change in fuel type from the Energy Centre, the potential impacts on air quality in relation to nitrogen dioxide emissions (a form of nitrogen oxide) are predicted to be significantly less than that reported in the 2013 ES and consequently mitigation measures are no longer considered necessary in relation to the Energy Centre. All other air quality pollutants predicted for the Development remain the same as the Consented Scheme. The potential impacts to air quality identified during the Site preparation and construction works remain as reported in the 2013 ES. Noise and Vibration Noise monitoring was undertaken at the Site in October 2013 to establish noise levels. The monitoring confirmed that noise levels were typical of a city centre urban environment and dominated by road traffic, primarily from Battersea Park Road and Nine Elms Lane. Noise was also noted from the adjacent railway, neighbouring Waste Transfer Station and CEMEX aggregates plant. Noise levels are considered to be comparable with the noise levels recorded in These noise levels were used to develop a three dimensional noise model to allow prediction of noise levels at properties considered most sensitive to noise, such as at Chelsea Bridge Wharf, within Chelsea and Pimlico on the opposite side of River Thames and along Battersea Park Road. Noise levels were also predicted at future residential properties, within the Development itself. Vibration was not considered to be an issue currently on the Site as no evidence of vibration resulting from road traffic or other sources was observed during the monitoring survey. During Site preparation and construction works, noise would likely be experienced at nearby residential properties and occupied properties within the Development as a result of demolition, excavation, and construction works on the Site, resulting in significant adverse impacts in the absence of mitigation. Construction traffic is also expected to increase noise levels, although on the majority of the roads assessed this was not predicted to be significant. The exception is along Cringle Street, although no residential properties are currently present along this road. The potential adverse impacts would be reduced through the implementation of measures, as set out in an EMP, such as locating plant away from residential properties, use of screens, and working within specified hours, as agreed with the LBW. During piling works within proximity to the Grade II* listed Power Station and associated listed structures, there is the potential for some damage (cracking) to the existing masonry and concrete. During such works, a vibration survey and inspection would therefore be undertaken to protect the building from damage. Once the Development is completed and operational, noise would likely be generated from uses within the Site such as from restaurants, bars and cafes, outdoor events and from operational building services plant. Noise levels would be kept to a minimum through adherence to noise level guidelines and therefore would not be expected to be significant. Based on the projected traffic volumes generated from the Development, the overall noise impacts from traffic on nearby residential properties was not predicted to be significant, with the exception of along Cringle Street and Page 27

36 Kirtling Street, where there are currently no existing residential properties. Consideration was also given to noise from the adjacent Cringle Dock, which is a Safeguarded Wharf. The Development near to the Cringle Dock Safeguarded Wharf would be designed to reduce potential noise conflicts of locating residential properties near to the Safeguarded Wharves. Suitable internal noise levels would be achieved using selective siting of proposed residential units combined with appropriate façade insulation, glazing and ventilation arrangements. Comparison with the Consented Scheme: The noise and vibration assessment concludes no significant change to the potential impacts associated with the Site preparation and construction works to those presented in the 2013 ES, largely because the existing noise levels at the Site have not changed significantly. However, owing to revised construction traffic data, which shows higher traffic volumes on both Battersea Park Road and Cringle Street compared to the construction traffic data used for 2013 ES, the potential noise impacts from construction traffic has changed along Cringle Street, with a predicted increase in noise levels. Similarly, for the Development, once completed and operational, the potential impacts are expected to be largely the same as reported in the 2013 ES. The exception relates to an increase in traffic generated noise along Cringle Street and Kirtling Street, which is predicted to have moderate and minor adverse impacts respectively. There is no significant change in the suitability of the Site for residential amenity compared with the Consented Development Ecology A desk-based study was undertaken to establish the ecological value of the Site in relation to the habitats and species present. This comprised a Site walkover in September and October 2013, together with a review of updated data from the Environment Agency, London Peregrines and Greenspace Information for Greater London. A number of surveys relating to bats, breeding and wintering birds, reptiles and invertebrates were undertaken on the Site between 2003 and 2013; the findings of which were used to inform the ecological assessment presented in the Phase 2 Amendment ES. The Site encompasses two ecological designated sites: Battersea Power Station Site of Borough Grade 1 Importance (SBINC: Grade I) located within the main part of Site; and The River Thames and Tidal Tributaries Sites of Metropolitan Importance for Nature Conservation (SMINC) located within the northern part of the Site covering the River Thames. The Site has been designated as an SBINC owing to habitats present on the Site which support a breeding pair of peregrine falcons as well as black redstarts, while the sparse vegetation provides an important feeding habitat for the black redstarts. The Power Station is also known to support roosting bats. The River Thames is valued for the variety of habitats it provides, including river walls, mud and sand and running water, which support many important fish and bird species. During the Site preparation and construction works, important brownfield habitats (suitable for nesting / sheltering and foraging) would temporarily be removed, including foreshore habitat as a result of works to the river wall and construction and dredging within the River Thames. Redevelopment of the Power Station would also result in the loss of roosting opportunities for bats, nesting opportunities for black redstarts and peregrine falcons. In addition, species on the Site could be exposed to some disturbance from construction noise, dust and lighting. To minimise adverse impacts on protected and notable species on the Site during construction works, works would be undertaken at appropriate times of the year, as detailed in the EMP, to minimise adverse impacts on the ecology of the River Thames. It is expected that following the works within the river, the river bed would revert back to its natural state. Page 28

37 Strategies have been already been developed to ensure that appropriate mitigation is in place to protect black redstarts and peregrine falcons. These measures were implemented prior to the commencement of Phase 1 Site preparation works to ensure these nesting and foraging opportunities are maintained for black redstarts and peregrine falcons. Similarly, a strategy has been developed which sets out measures to minimise impacts on bats, including the provision of replacement roosting opportunities. As part of the Development, significant landscaping, including green and brown roofs and water features, would be incorporated that would mitigate for the loss of habitat during construction. Such features would support protected and notable species on the Site, most notably, peregrine falcons and black redstarts. Any new storm water outfalls to the River Thames would be carefully designed to ensure any potential impacts on the foreshore are minimised. Comparison with the Consented Scheme: The majority of the protected and / or notable species (bats, peregrine falcons, black redstarts, notable, terrestrial and wintering birds, fish and intertidal and subtidal macroinvertebrates) are considered to remain valid from the 2013 ES. However, reptiles are no longer considered to be present on the Site and terrestrial invertebrates have lost the majority of suitable habitat recorded in 2008 due to clearance works associated with Phase 1 of the Development. Nevertheless, the potential impacts identified with the assessment presented within this Phase 2 Amendment ES for both the Site preparation and construction works and the Development, once complete, remain largely as identified for the 2013 ES. The most notable exception relates to clearance of vegetation on the Site suitable for birds and invertebrates, which has resulted in the potential impacts being less significant than previously identified. In addition, the temporary jetty of the Consented Scheme would be relocated to the eastern end of the existing jetty, which would remove the requirement for dredging and piling of the River Thames. There has also been an amendment to the drainage, whereby no new outflows are proposed to the River Thames within this phase, which would minimise the impact on the habitats within foreshore of the River Thames. Townscape, Conservation and Visual Impacts A desk-based study of the townscape, conservation and visual impacts was undertaken taking account skyline of London, the physical fabric and character of the area, together with the appropriateness of the Site for tall buildings. The assessment was supported by accurate visual representations of 44 viewpoints (as illustrated in Figure 8 and Figure 9) that were agreed with the LBW. The selected views allowed the potential townscape, conservation and visual impacts of the Development and its likely impacts on the setting of heritage assets to be assessed. Taken together, they illustrate the impact of the Development on existing views, its relationship to its urban and riverside context and on the settings of heritage assets. Whilst the Site is not located within a conservation area, the Site adjoins the Battersea Park conservation area, which extends to the west. The Park was opened by Queen Victoria at The Site itself incorporates the Grade II* listed former Power Station, jetty, cranes and river wall, together with the Grade II Pumping Station. All these buildings and structures contribute to the local townscape character. There are also a number of conservation areas and listed buildings in the surrounding area including. The Site is located within the Vauxhall, Nine Elms and Battersea Opportunity Area which is currently undergoing significant regeneration, where a number of large former industrial sites are being redeveloped. Whilst the Site is not located within viewing corridors defined by the Mayor of London to protect the World Heritage Site of the Palace of Westminster, the Site would potentially be distantly visible from Parliament Hill and Primrose Hill. The Site would be prominent in a number of locally Page 29
