The site falls within Flood Zone 1, therefore is not at risk of tidal flooding.
Surface water run-off from rainfall from the developed site will be managed through the introduction of new Sustainable Drainage Systems (SuDS). The SuDS will include an improvement in the quality of rainwater discharged from the development.
The proposed SuDS will ensure surface water is captured at the source and released at a lower rate than that which reflects natural systems. It will also aim to control the water at the source and reuse where possible, including in the rain garden.
SuDS features will significantly improve rainwater drainage compared with the existing situation and will account for peak rainfall with an allowance for an additional 40% buffer for stormwater runoff.
The proposals will result in a reduction in the potential from flooding locally, by controlling the discharge from the development into the local sewer network. The design will control all peak flows including a generous allowance for the effects of climate change.
