Bioretention Type | Variant | Underlying Soil Performance Criteria |
---|---|---|
Infiltration/Recharge Facility | No underdrain | Higher recharge potential (facility drain time without under-drain is 48 hours) |
Filtration/Partial Recharge Facility | Underdrain | Lower recharge potential (facility drain time without under-drain is > 48 hours) |
Infiltration/Filtration/Recharge Facility | Elevated underdrain | Higher nutrient loadings and/or quantity control |
Filtration Only Facility | Underdrain with liner | Hot Spot Treatment |
