WebThe LLFA preference is that greenfield runoff rates should be calculated using the following rainfall data: FSR and FEH, and should be calculated using the IH124 method. Alternatively, the ICP SuDS method can be used which is the IH124 with sites below 50ha having a pro rata applied. WebTools for the design and evaluation of sustainable drainage systems (SuDS) Our focus is entirely on water. The complex challenges it brings.

WebGreenfield runoff rate is the runoff rate from a site in its natural state, prior to any development. Proposals for higher discharge rates should be agreed with the LBB ahead … WebLong Term Storage. Where using flow matching long term storage should be included. The introduction of new areas of hardstanding as part of development is likely to increase runoff volumes from a site. When limiting all discharge back to the 1 in 1-year greenfield rate the benefit of the reduction is discharge rates for larger events will ...
