Summary of Bioretention Variants for Permeability of Native Soils and Potential Land use Pollutant Loading
Summary of Bioretention Variants for Permeability of Native Soils and Potential Land use Pollutant Loading
(Link to this table)
| 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 |
