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.

Winter maintenance[edit]

Salt can be damaging to the planting in parking lot bioretention. To help minimise this, bioretention practices adjacent to parking areas should always have an underdrain and slat use be reduced through good design and planning of the parking lot.
