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 m<sup>2</sup>.

Partial infiltration bioretention cell draining a parking lot. Designs for this type of LID practice vary, but typically include a water storage reservoir, optional choker layer, filter media layer, mulch and vegetation. Other design variations include full infiltration and no infiltration configurations which can be explored with their own image maps.

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 minimize this, bioretention practices adjacent to parking areas should always have an underdrain and salt use be reduced through good design and planning of the parking lot.
