SUDS can also improve runoffquality and the amenity value of surfacewater.• Pervious surfaces and pavements• Swales, basins and drainage channels• Ponds, wetlands & rain gardens• Infiltration trenches and filter drains• Green roofsGreen infrastructureGreen infrastructure is the physicalenvironment within and between ourcities, towns and villages. It is a networkof multi-functional open spaces, includingformal parks, gardens, woodlands, greencorridors, waterways, street trees and opencountryside. When designed and maintainedcorrectly, greenspace can reduce surfacewater flood risk, reduce peak runoff flows,capture runoff for reuse, ameliorate localisedUrban Heat Island (UHI) effects, improvebiodiversity habitat, and improve runoffwater quality.Three Regions Climate Change Group,Adapting to Climate Change – A Checklist forDevelopment.Possible interventionsIncreasing the amount and quality of urbangreenspace within all areas of VNEB.• Dedicated public and private greenspaces• Communal open space for new residentialand commercial developments• Green corridors along public walkways,roads and site infrastructure• Street tree plantingPolicy reference & signpostCIRIA The SUDS ManualLondon Plan:• 4A.13 Flood risk management• 4A.14 Sustainable drainage• SPG Sustainable Design and ConstructionDEFRA & CIRIA.

Loss less: Reduce the loss of waterthrough better leakage management2. Use less: Improve the efficiency ofwater use in residential and commercialdevelopment3. Reclaim more: Use reclaimed waterfor non-potable uses (grey waterand rainwater)New resources: develop, as necessary, thosewater resources that have the least climatechange and environmental impact.Policy reference & signpostCode for Sustainable HomesAECB Water StandardsLondon Plan• 4A.16 Water supplies and resourcesAll water use devices and appliances shouldbe water efficient, including;Shower heads, aerated and spray taps,low-flow and dual flush toilets, washingmachines, dishwashers, water butts, vacuumdrainage systems and waterless urinals.Xeriscaping - The specification of droughttolerant native plant species in parks andgardensThe use of non-potable water for streetcleaning and vehicle wash-down.Harvesting of rainwater is simply thecollection of water for domestic orcommercial use that would otherwise godown the drain. Today, rainwater harvestingsystems can be installed in both new andexisting buildings and can range from aquick, cheap water butt to a more complexsystem. Rainwater can be used for thegarden, washing the car, showering, flushingthe toilet and the washing machine.Consideration of rainwater harvesting musttake into account the cost and carbonemissions associated with providing watercompared with mains water, due to therelience on pumping and filtration systems.Policy reference & signpostLondon Plan• 4A.14 Sustainable drainage• 4A.16 Water supplies and resources• SPG Sustainable Design and ConstructionCIRIA Rainwater Harvesting StandardsPossible interventionRainwater capture into water infrastructurewithin multi-functional open spaces for greenspace and street tree use.Borehole abstraction and advanced watertreatment to potable standards.Borehole abstraction for direct non-potablesupply.Green roofs on commercial anddomestic buildingsVegetated roofs and walls, including terracesand gardens, can improve the thermalperformance of the building, reduce theurban heat island effect, absorb rainfall toreduce flash flooding, enhance biodiversity,provide amenity for residents who may nothave access to private gardens and improveappearance.Policy reference & signpostLondon Plan policies:• 4A.14 Sustainable drainage• 4A.15 Rising groundwater• 4A.16 Water supplies and resources seekto promote sustainable urbandrainage systems, the abstraction anduse of groundwater and to protect andconserve water supplies and resources.Rainwater harvesting systems for nonpotablewater, for both commercial anddomestic development use.Preference for systems that use gravity feedover pump systems.GLA – Living Roofs and Walls: TechnicalReport: Supporting London Plan Policy
