Line 285:
Line 285: + + − ===Inlets=== − Multiple methods for distribution and conveyance of runoff into the system are recommended for redundancy and conservative designs. − Combinations may be made of: − *tree well flow, − *catchbasins and distribution pipes, and − *direct infiltration from permeable paving. − See also [[Inlets]] and [[pretreatment]] −

*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.

*Structures are designed to be filled with growing medium for tree rooting and support a vehicle loaded pavement up to and including AASHTO H-20 and Ontario Building Code standards for sidewalks.
*Critical to modular soil support system design is that each structure or layer of structures be independent of all adjacent ones, such that one or multiple layers can be removed to facilitate future utility installation or repair.
