To read about the use of stormwater tree trenches featuring soil cells in the GTA see the STEP case study on [https://sustainabletechnologies.ca/app/uploads/2018/10/Queensway-Case-Study_FINAL.pdf The Queensway Sustainable Sidewalk Pilot Project]. Evaluations of the project found that stormwater tree trenches are able to increase the urban street tree canopy coverage while requiring minimal surface area below, and provide stormwater benefits associated with TSS and heavy metal contaminant removal and runoff volume reduction, with lower routine maintenance costs than other surface practices like bioretention.<ref>STEP. 2018.
