This table shows structural BMP use in soil with low infiltration capacity
Link to this table
BMP | Low infiltration capacity soil considerations |
---|---|
Bioretention, dry swale, permeable pavement, tree trench/box | Should be constructed with an underdrain. Recharge criteria, if applicable, can be met by modifying the design to include an infiltration gallery below the underdrain, so long as it is appropriately sized. |
Media filter | Recommended practice in tight soils. Some design variants can be modified to incorporate an infiltration gallery that can help meet recharge criteria, if properly sized. |
Infiltration trench or basin |
|
Stormwater ponds | Acceptable practice with tight soils. Soils should help maintain permanent pool. |
Constructed wetlands |
