Things to consider in design:
*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 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]] or no-infiltration design [[bioretention]] cell and should provide similar water quality benefits.

*Depending on design details tree trenches may retain a significant volume of stormwater within the planting soil and internal water storage layer and provide runoff volume reduction benefit.
