Water Environment Limited was commissioned to undertake a Flood Risk Assessment, a SuDS strategy and prepare an Environmental Statement chapter covering Flood Risk, Drainage and Water Resources.
The site forms part of the Charlton Riverside Opportunity Area:
(http://www.royalgreenwich.gov.uk/downloads/file/1267/charlton_riverside_masterplan_spd_april_2012_- _chapters_1_to_3).
The site lies in defended Flood Zone 3 with a greater than 1% annual probability of flooding, however it is formally protected by the Thames Barrier and linear defences along the River Thames. A Flood Risk Assessment was therefore required to assess the impact of the development on flood risk and water resources. As a ‘Major’ development (10 or more dwellings) detailed drainage strategy was developed, incorporating the use of SuDS to ensure that runoff from rainfall events with return periods up to 100 years (including climate change) is managed on-site, and peak runoff rates meet the requirements of the Environment Agency and the Mayor of London. Following negotiations, the Environment Agency did not object to the proposed development. The ES chapter on Water covered Flood Risk, Drainage and Water Resources. Both the construction and occupational stages of the development were considered.
