*If the system is unlined it is hydraulically equivalent to a [[bioretention]] cell and provides similar water quality benefits.

*If the system is lined and underdrained it is hydraulically similar to a large [[stormwater planter]]. Depending on the design detail it may retain significant stormwater within the planting soil volume and will provide water quality benefits.
