2. What is it? In ground containers or a concrete bottomless box
Contains street trees
Mostly found in urban areas
Runoff (rainwater) is directed to the tree box, where it is filtered by vegetation and soil before entering a catch basin
Similar to bioretention principles used in rain gardens, which enhance pollutant removal, improve reliability, standardize and increase ease of construction, and reduce maintenance costs.
It has a underdrain consisting of a pipe surrounded by drain rocks and is engineered to bio filtrate (captures harmful chemicals) with mulch on top that supports the plants.

3. Why is it used? Used to manage stormwater (excess water/run off)
Tree box filters decrease the amount of discharge by detaining stormwater volume and by regulating the amount of discharge
Brings aesthetic value to a city
One tree box holds gallons of water
