[[File:Stormwater Tree Trench high permeability native subsoil with soil cells.png|thumb|center|450px|'''Tree Trench with High Permeability Subsoil, with Soil Cells''' - This tree trench configuration possess high permeability soil, similar to the configuration on the right, but instead of structural soil this tree trench contains soil cells or 'modular soil support systems'.  Soil cells are an alternative to structural soil media and are used adjacent to tree pits to provide room for tree roots to spread out under paved surfaces surrounding the tree trench. The growing media in soil cells typically has higher organic content than structural soils and with a looser structure and higher nutrient content of the soil, these support systems provide the most favourable environment for healthy tree growth in the urban setting.]]
