To read about the use of soil cell systems in the GTA please take a look at the following STEP report on the [https://sustainabletechnologies.ca/app/uploads/2018/10/Queensway-Case-Study_FINAL.pdfThe Queensway Sustainable Sidewalk Pilot Project]. The project found that Stormwater Tree Trenches are not only able to increase the urban street canopy coverage, while impacting minimal surface area below, but numerous stormwater benefits associated with TSS removal and heavy metal contaminant removal. Finally, the study found that the feature was also able to reduce stormwater volumes leaving the street tree system and promoted increased LID use in a heavily urbanized setting without increased maintenance costs associated with other daylighted bioretention swales.<ref>STEP. 2018. he Queensway Sustainable Sidewalk Pilot Project - Case Study: Low impact Development Series. https://sustainabletechnologies.ca/app/uploads/2018/10/Queensway-Case-Study_FINAL.pdf.</ref>
