What is greenfield deployment and when is it used?

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. WebGreenfield Runoff Calculations The methods outlined within the calculating runoff rates section should be utilised. Note that the Q (1yrs) (l/s) pre-development runoff values are expected to be met by developments in Essex for greenfield sites. WebWith reference to Appendix I, The UKSuds.com Greenfield Runoff Tool was used to calculate the allowable runoff rates. Using the IH124 Methodology the greenfield runoff rates are calculated as follows: Q BAR = 1.74 l/s for a 1:100-year event Therefore, the allowable outflow has been calculated below. cannot leave a pokemon while gym under attack
