The maximum drainage catchment to be modeled per the Presumptive Approach is 1 acre (43,560 SF)
=or infiltration facilities in Class A or B soils where no infiltration testing has been per romed use an infiltration rate of 0.5 in/hr.
For all facilities use a maximum soil infiltration rate of 2.5 in/hr for lommi/growing medium.
