Stormwater Tree Trenches

Summary

A stormwater tree trench is a subsurface trench with a stone reservoir for stormwater runoff retention and conveyance and sections of engineered soil for growth of street trees. It manages stormwater runoff by collecting surface runoff via inlets and overland flow and conveys these surface flows to the subsurface trench. The runoff is stored temporarily between the voids in the stone reservoir and provided needed water to the street trees.
