1 Table 1.3: Summary of Eliminated Significant Residual Impacts Route Window Environmental Topic Summary of Significant Residual Impacts C6 and C7: Farringdon Station and Liverpool Street Station Townscape Visual Amenity Visual Amenity Traffic and Transport Traffic and Transport Elimination of a significant temporary adverse impact on the quality and setting of the podium of the Grade II listed Barbican and gardens complex, the area designated as a Grade II* Parks and Gardens of Special Historic Interest by English Heritage. Elimination of a significant temporary adverse impact on a number of visual receptors overlooking the original Farringdon crossover worksite and Aldersgate Street sewer worksite and the pedestrian users of streets with views of these worksites. Elimination of impacts on workers at the Telephone Exchange Building, and workers and visitors at 3 6 Fore Street Avenue. Elimination of significant temporary adverse impacts resulting from the worksite and shaft at Aldersgate Street. Elimination of significant adverse impacts of particular importance resulting from the utilities diversions that would have been necessary in Aldersgate Street both in its own right and in combination with the works at Farringdon, Moorgate and Liverpool Street. 11

2 Table 1.3: Summary of Eliminated Significant Residual Impacts (continued) Route Window Environmental Topic Summary of Significant Residual Impacts C12: Mile End Park and Eleanor Street Shafts C13 and C13A: Pudding Mill Lane Portal and Abbey Mills Visual Amenity Community Visual Amenity Traffic and Transport Noise and Vibration Elimination of a significant adverse impact on the workers at a proposed commercial building on the western side of Eleanor Street and south of the District line railway (the laundry building) because the building will now be demolished. Elimination of a significant adverse impact to residents of the travellers site reported in the main ES due to their proposed relocation. The revised scheme will eliminate significant adverse impacts for sensitive receptors as a result of omitting a number of worksites at Pudding Mill Lane, Leggatt Road and Abbey Mills pumping station. A review of construction methodology for working in the Blackwall Way Northern Approach Road has identified that the additional mitigation of working at night can be adopted. The revised scheme will avoid major traffic disruption on a strategic route, which was assessed as a significant adverse traffic and transport impact of particular importance, by undertaking proposed works at the Blackwall Tunnel worksites at night, rather than during daytime hours. Since the worksites in Route Window C13A are no longer required there will be no significant adverse noise impacts on the 84 properties identified in the main ES in Route Window C13A and hence there will be no need for noise insulation. W15: Dog Kennel Bridge Visual Amenity Elimination of a significant adverse impact on visual amenity for residents at the southern end of Southwold Spur. 12

3 Summary of Impacts Route Window C1: Royal Oak Portal The extension of sidings and associated work on the retaining wall and Westbourne Park Passage footbridge does not change the significant impacts or proposed mitigation as set out in the main ES with respect to landscape, townscape and built heritage, visual amenity, noise and vibration, air quality, archaeology, ecology, water resources, contaminated land, and socio-economics. The revised scheme will generate a significant temporary adverse impact on traffic and transport and the community as the required temporary closure of the Westbourne Park Passage footbridge for up to two months will result in a pedestrian route diversion.

4 Route Windows C6 and C7: Farringdon Station and Liverpool Street Station The proposed temporary works do not change the significant impacts or proposed mitigation as set out in the main ES with respect to archaeology, air quality, contaminated land, water resources, community or socio-economics. Additional mitigation measures will be employed to ensure there will be no additional significant impacts with respect to ecology and noise and vibration. The removal of the Farringdon crossover worksite in Aldersgate Street will eliminate the significant adverse impact on the setting of the listed Barbican complex, significant adverse impacts on the visual amenity of a number of receptors overlooking the worksite, and a significant adverse impact on traffic and transport. Since utility diversions in Aldersgate Street will no longer be required, a significant adverse impact of particular importance on traffic and transport resulting from works in Aldersgate Street and in combination with other works in the vicinity will also be eliminated. Aerial view looking north along Moor Lane The new worksite at Moor Lane will result in additional significant temporary adverse impacts on visual amenity for pedestrians using Moor Lane, pedestrians using Britannic Highwalk adjacent to and across Moor Lane, and visitors to and workers at the southwestern corner of the City Point complex that faces Moor Lane. If compensation grout shafts are required in the Barbican basement car parks to mitigate impacts associated with predicted settlement at the Barbican, the loss of car parking spaces will result in a significant temporary adverse impact on traffic and transport. 14

5 As a result of changes to the Moorgate station sewer diversion, significant temporary adverse impacts on visual amenity for workers at the Telephone Exchange Building, and for workers and visitors at 3 6 Fore Street Avenue, will be eliminated. Route Window C12: Mile End Park and Eleanor Street Shafts The reconfiguration of the travellers site does not change the significant impacts or proposed mitigation as set out in the main ES with respect to landscape, townscape, built heritage, archaeology, ecology, traffic and transport, air quality, water resources, contaminated land or socio-economics. Aerial view of Bow Triangle looking east The revised scheme will generate a significant temporary adverse impact on the visual amenity of residents at the reconfigured travellers site. However, a significant adverse temporary impact on visual amenity of workers at the laundry building will be eliminated because the building will now be demolished. Since the travellers are no longer relocated off-site, the permanent significant adverse impact on the community will no longer occur. A higher hoarding than previously proposed will be provided around the Eleanor Street worksite. With this in place, there will be no additional significant noise and vibration impacts to those already reported in the main ES. 15

6 Route Windows C13 and C13A: Pudding Mill Lane Portal and Abbey Mills The proposed works to divert the HAM and WL sewers do not change the significant impacts or proposed mitigation as set out in the main ES with respect to archaeology, ecology, air quality, water resources, contaminated land or socio-economics. Under the revised scheme, the suspension of a number of resident parking bays in Payne Road, Wrexham Road, Baldock Road and Wick Lane and the loss of off-street private parking at the southern end of Baldock Street to allow the safe manoeuvring of construction vehicles will give rise to a temporary significant adverse impact on traffic and transport to local residents. The increase in traffic in Wick Lane, Wrexham Road and Baldock Street will result in a significant adverse temporary community impact. The revised scheme will also result in a temporary significant adverse impact on the setting of the Grade II listed Manhattan Building (former Bryant and May factory) during the construction phase. Aerial view of the proposed Manhattan Shaft site looking east along the Great Eastern Main Line 16 Residential properties in the Manhattan Building, Ridgedale Street, Grove Hall Court, Baldock Street, Brymay Close and Wrexham Road will be subject to significant adverse daytime and in some cases night-time construction noise impacts from activities at the HAM and WL sewer diversion worksites. Furthermore, the works have the potential to result in significant adverse construction noise impacts to noise-sensitive parts of proposed new mixed use developments at Payne Road and Fairfield Road.

7 The revised construction works will result in numerous receptors in the vicinity of the new worksites experiencing significant temporary adverse impacts on visual amenity in addition to those already reported in the main ES. As a result of omitting worksites at Marshgate Lane/Pudding Mill Lane, Claypole Road/Leggatt Road and at Abbey Mills pumping station, the revised scheme will eliminate significant temporary adverse impacts on visual amenity for a number of sensitive receptors overlooking the worksites. In addition, as a result of omitting these worksites, there will be no significant residual noise impacts at 84 properties previously identified in the main ES in Route Window C13A as having the need for noise insulation. These properties will no longer require such mitigation as a result of the Amendment.

8 Route Window W15: Dog Kennel Bridge The proposed road alignment and changes to bridge construction at Chequer Bridge do not change the significant impacts or proposed mitigation as set out in the main ES with respect to landscape, townscape and built heritage, archaeology, ecology, noise and vibration, air quality, water resources, contaminated land, traffic and transport, community or socio-economics. As a result of the change in the scheme, the significant adverse impact on visual amenity for residents at the southern end of Southwold Spur will be eliminated. Route Window SE2: Custom House The proposed changes to the construction access routes at Seagull Lane do not change the significant impacts or proposed mitigation as set out in the main ES. Aerial view of Chequer Bridge looking east along the Great Western Main Line Route Window SE6: Plumstead Portal The alternative location of the temporary works does not change the significant impacts or proposed mitigation as set out in the main ES. 18
