Differences between infiltration basins and bioretention basins

Summary of factors that can be used to determine differences between infiltration basins and bioretention basins. This table corresponds with Table 1 in the flowchart [1].

BMP	Typical position in watershed	Treatment scale	typical storm sizes	Maximum drainage area guidelines	Maximum ponding depth guidelines	Growing medium
Infiltration basin	Downgradient of other water quantity or water quality control practices	Development or regional scale control	Less frequent large storm events that exceed capacity of upgradient practices	50 acres	4 feet	Native soil
Bioretention basin	located throughout the watershed	Site scale control	Small storms (water quality events)	typically 5 acres	ideally 12 inches; can be up to 18 inches with appropriate design and plant selection	Engineered growing medium
