Some form of stormwater landscaping (bioretention) can be fitted into most spaces. Although there are some [[Infiltration#Constraints|constraints]] to infiltrating water, it is preferable to do so where possible.

:For ease of construction and to ensure that the vegetation has adequate space, cells should be no narrower than 0.6 m at any point.

:The maximum width of a facility is determined by the reach of the construction machinery, which must not be tracked into the cell.

The principles of bioretention can be applied in any scenario where planting or vegetation would normally be found.
*Setback from Buildings: A typical four (4) metre setback is recommended from building foundations. If an impermeable liner is used, no setback is needed.
*Proximity to Underground Utilities and Overhead wires - consult with local utility companies regards to horizontal and vertical clearance required between storm drains, ditches, and surface water bodies. Further, check whether the future tree canopy height in the bioretention area will not interfere with existing overhead wires
