| Bioretention Type | Variant | Underlying Soil Performance Criteria |
|---|---|---|
| Infiltration/Recharge Facility | No underdrain | Higher recharge potential (facility drain time without underdrain is 48 hours) |
| Filtration/Partial Recharge Facility | Underdrain | Lower recharge potential (facility drain time without underdrain 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 |
