volume "Vd? and total proposed impervious area "Aimp” from the "Annual Recharge” sheet to der" and "Aimp" on this page. This allows solution for a single BMP to handle the entire recharge requirement assuming the runoff from entire impervious area is available to the BMP. To solve for a smaller BMP or a LID-IMP to recharge only part ofthe recharge requirement, set Vdef to your target value and Aimp to impervious erea directly connected to your infiration feclty and then solve for JABMP or dBMP.
