Things to consider in design:

*If the trench is unlined it is hydraulically similar to a [[bioretention]] cell and should provide similar water quality benefits.   

*If the trench is unlined it is hydraulically similar to a full- or partial-infiltration design [[bioretention]] cell and should provide similar water quality benefits.   

*If the trench features an impermeable liner and underdrain it is hydraulically similar to a large [[stormwater planter]].  

*If the trench features an impermeable liner and underdrain it is hydraulically similar to a large [[stormwater planter]] or no-infiltration design [[bioretention]] cell and should provide similar water quality benefits.  

*Depending on design details it may retain significant stormwater within the planting soil volume and will provide water quality benefits.   

*Depending on design details it may retain a significant volume of stormwater within the planting soil.
