Note that some of these parameters are limited:

#The ''maximum'' total depth will be limited by construction practices i.e. usually ≤ 2 m.

#The ''maximum'' total depth will be limited by construction practices i.e. usually ≤ 2 m.

#The ''maximum'' total depth may be limited by the [[Infiltration| conditions underground]] e.g. the groundwater or underlying geology/infrastructure.

#The ''maximum'' total depth may be limited by the [[Infiltration| conditions underground]] (e.g. the groundwater or underlying geology/infrastructure).

#The ''maximum'' total depth may be limited by the need to support vegetation on top of it (e.g. at least 30 cm of planting soil fill above the BMP to support grasses)

#[[Green roofs]], [[absorbent landscapes]] and [[permeable paving]] often receive very little flow from other surfaces, so that the I/P ratio is typically between 0 and 2.
