This table shows the summary of climate, soil and terrain factors that affect the selection of Best Management Practices.
Link to this table
| BMP | Karst | Bedrock and shallow soils | High snowfall - meltwater treatment | Low rainfall | |
|---|---|---|---|---|---|
| Bioretention - no underdrain | Not recommended. Extensive pre-treatment required | Not recommended due to separation distance | OK. Use salt-tolerant vegetationand pre-treatment. Chlorides will move through untreated. | OK. Use appropriate vegetation. | |
| Bioretention with underdrain | OK. Under certain conditions use impermeable liner | Recommended. | OK. Use salt-tolerant vegetationand pre-treatment. Chlorides will move through untreated. | OK. Use appropriate vegetation. | |
| Filtrationa | OK. Under certain conditions use impermeable liner | Recommended | OK. Place below frost line. Use pre-treatment. Chlorides will move through untreated. | Recommended. | |
| Infiltrationb | Not recommended. Extensive pre-treatment required | Not recommended due to separation distance | OK but could be limited. Active management needed to prevent infiltration of chlorides and soluble toxics. | Recommended | |
| Stormwater ponds | OK. Under certain conditions use impermeable liner; limit depth; geotechnical investigation needed. | Limited due to available depth and large surface area requirement. | Recommended. Limit depth to avoid stratification. Adapt outlet structure. | Limited. Water budget calculations may show this to be unsuitable. | |
| Constructed wetlands | OK. Under certain conditions use impermeable liner; limit depth; geotechnical investigation needed. | OK. Large surface area. | OK. Use salt-tolerant vegetation. | Limited. Water budget calculations may show this to be unsuitable. |
aSee sand filters, Dry swale (Grass swale), High-gradient stormwater step-pool swale, or Wet swale (wetland channel)
bSee infiltration trench or infiltration basin
