CBRE | ST GEORGE SOUTH LONDON LTD8.0 Planning Policy Assessment8.255 A summary of the pertinent conclusions not already discussed are set out below.Water Resources and Flood Risk8.256 Chapter 14 of the ES concludes that no significant impacts on water resourcesduring the construction phases are expected provided a series of mitigationmeasures are followed. However, the impact of increased demand and waste watergeneration is anticipated to be of minor adverse.8.257 A Flood Risk Assessment (FRA) for the Proposed Development has been undertaken,which details the full mitigation proposals to manage flood risks. Flood resilientconstruction measures have been included on the basement and ground floor levelsto reduce the impact of a flood event on the building. The FRA includes assessmentof the surface water drainage issues and conceptual drainage design. The FRAdetails the measures, attenuation tanks and the incorporation of green roofs, toreduce surface water flows in order to meet relevant planning policy. The ProposedDevelopment would have a minor beneficial impact on flood risk.Ground Conditions8.258 Chapter 15 of the ES identifies the potential for contamination on the Site andconcluded that further intrusive investigation work would need to be undertaken anda range of mitigation measures employed throughout the construction period. Theoperational phase would have negligible impacts on ground conditions.Noise and Vibration8.259 Chapter 11 of the ES concludes that during the construction phase, vibration fromconstruction works would have negligible to minor adverse impacts whilstconstruction traffic and noise would have a negligible impact. Best practice measureswould be followed to mitigate against impacts by reducing the duration andmagnitude of noise on sensitive receptors.Page 55PLANNING POLICY ASSESSMENT8.260 In the operational phase, traffic is considered to be of negligible significance whilstplant would be designed to have a rating 10 dBA below the background noise level.Negligible impacts are expected on this basis.Air Quality8.261 Chapter 10 of the ES concludes that the proposed development would have minoradverse to neglible impacts in the construction phase due to the potential forconstruction dust. However, these would be of temporary duration and local extent.Mitigation measures would be implemented to minimise any adverse impacts on airquality in line with the relevant guidance.8.262 The potential sources of impacts to air quality from the Proposed Developmentwould be from road traffic and heating and plant power emissions. The increasedvehicles on the surrounding road network, travelling to and from the Site, wouldhave a negligible impact. It was not considered necessary to mitigate atmosphericemissions associated with traffic flows with the completed and operationaldevelopment it is expected to have a negligible impact to local air quality at nearbysensitive receptors.8.263 The heating and power plant on site would have a minor adverse impact on thelocal surrounding air quality in the long term, however it is predicted that during
