Stormwater Management,
Healthy Trees and the Urban Environment
ADD-ON OPTIONS / APPLICATIONS
Since no two project sites and their requirements are the same, StormTree recognizes the need for optional features to satisfy various site conditions or to enhance the functionality of its systems.
​
StormTree systems are designed for versatility. Systems can be combined with trees, seating, bicycle racks or other architectural elements.
Impermeable Liner
Although the many benefits of the StormTree open design system are apparent, there may be site situations where direct infiltration of water to the subsurface may not be desirable or may be problematic.
​
Nearby sensitive receptors such as water bodies or wellhead protection zones may need to be safeguarded, or a nearby building foundation may need protection from water intrusion. In such cases, a low cost, landfill grade, flexible impermeable liner may be installed to envelope the entire StormTree system, or in the case of a building foundation, as a vertical “curtain” wall separating the system from the nearby building.
Whatever the site constraints, since the StormTree structure is open on two or more sides, it allows for the extension of the soil/media footprint (and the liner) beyond the structure, providing a greater treatment zone and extended root area.

Stormwater Collection Chambers
Whether the purpose is for the controlling of high intensity rainfall events, rainwater harvesting for supplemental irrigation, the underground detention or retention of water is an important asset. StormTree systems can easily be integrated with commercial plastic stormwater chambers. The narrow profile of most chambers allow for in-line installation beneath sidewalks stretching from one city block to the next.
StormTree systems can be constructed to direct infiltrated water directly to underlying chambers and/or designed with an internal overflow pipe to bypass excess water directly to the same chambers.
​
In hurricane or flood prone areas, the collection and short-term storage of excess water underground could provide temporary relief during the height of the storm event thereby reducing a flooding risk.
In drought prone regions of the country, stormwater is an important resource valued for harvesting and collection to provide supplemental irrigation to the urban landscape during lean periods of rainfall.
