The long-term intention of the London Strategic SuDS Pilot Study (LSSPS) was to develop a strategy for retrofitting SuDS delivery that could be rolled out in surface water catchments, aligning them with existing public work programmes where possible to improve efficiency. This has the potential to provide cumulative flood risk protection that meet the standards required to release Flood and Coastal Erosion Risk Management (FCERM) Grant in Aid (GiA) and Levy funding. The inclusion of the multiple benefits can further strengthen the business case and attract partnership funding.
SuDS deliver more for less – the study demonstrates that by using hydraulic modelling to target key locations and/or integrating SuDS measures into wider public realm works, Distributed SuDS can deliver a greater benefit more efficiently.
