The Flood and Water Management Act 2010 and Flood Risk Regulations 2009 have designated Unitary Authorities and County Councils as Lead Local Flood Authority (LLFA). LLFAs have responsibility for leading the co-ordination of local flood risk management in their respective administrative areas, ensuring that flood risk from all sources, including from surface runoff, groundwater and ordinary watercourses, is identified and managed as part of locally agreed plans and strategies.
A Surface Water Management Plan (SWMP) assesses the surface water flood risk across an area using both historical information and undertaking pluvial modelling to determine the future flood risk for a range of rainfall events. These identify the areas of significant surface water and groundwater risk and options to address the risk of flooding.
A SWMP has been produced for the London Borough of Richmond upon Thames, along with the Preliminary Flood Risk Assessment, as part of the Drain London project.
