On commercial, industrial and multi-unit developments, a popular choice is to integrate bioretention into parking lot landscaped areas. These distributed cells typically accept sheet flow through multiple curb cuts, have shallow depression storage ≤ 100 mm, and a total area of 5 -200 m2. Although many parking lot schemes include long linear bioretention cells (≥ 0.6 m wide), infiltration is optimized by having a level grade and a level base, unlike a bioswale.
