Typology 3 – Covered back of kerb raingarden tree pit
Covered back of kerb raingarden tree pits are suitable for heavily used footpaths where there is limited space behind the back of kerb that is not essential for pedestrian movement or other street functions.
The cover above the filter media ensures minimal impact on the width of the footpath available for pedestrians. Stormwater flows from the street gutter through a kerb inlet into a sunken tree pit and percolates through the soil to perforated pipes in the base of the tree pit.
