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