City of London School (For City of London Corporation)
UK Flood Risk was commissioned to prepare a Flood Risk Assessment (FRA) in support of a proposal at the City of London School, 107 Queen Victoria Street, London EC4V 3AL. The site lies within the Flood Zone 3 (high probability flooding) with the risk of tidal flooding from the River Thames. We undertook a detailed assessment of tidal flood risk arising from the River Thames. For this, a detailed assessment of the Environment Agency’s most up-to-date tidal modelling data and information. An assessment of the data and information derived from the Thames Estuary 2100 study was undertaken to determine the risk of overtopping of the flood defences during the extreme event of 0.5%AEP (1 in 200 year) at present and in the future. Also, assessment was done using the Thames Tidal Upriver Breach Inundation Modelling Study 2017. A number of mitigation measures were proposed in order to mitigate the risk of flooding. Also, a site-specific Personal Flood Plan (Flood Warning and Evacuation Plan) was developed for the site.
Greenwich Framework for Royal Borough of Greenwich
UK Flood Risk was commissioned by Royal Borough of Greenwich to undertake a Flood Risk Assessment (FRA) in support of a proposal consisting of residential development at three sites located at Ridgebrook Road, Bournbrook Road and Halsbrook Road, Greenwich. We assessed available data, information and evidence to determine the level of flood risk from a range of sources including fluvial, surface water, groundwater, sewer and artificial water bodies. Several flood risk mitigations and Sustainable Urban Drainage Systems (SuDS) measures were proposed for the site for the mitigation of flood risk, especially from surface runoff. The mitigations were proposed to ensure that the development will not give rise to backwater affects or divert water towards other properties. The FRA concluded that the proposed development will be safe, in terms of flood risk, for its design life and will not increase the flood risk elsewhere.
