Things to consider in design:
Things to consider in design:
*If the system is unlined it is hydraulically equivalent to a [[bioretention]] cell and provides similar water quality benefits.
*If the system is unlined it is hydraulically equivalent to a [[bioretention]] cell and provides similar water quality benefits.
*If the systems is lined, it is hydraulically similar to a large [[stormwater planter]]. Depending on the design detail it may retain significant stormwater within the planting volume soil and will provide 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.

Multiple methods for distribution and conveyance of runoff into the system are recommended for redundancy and conservative designs.
