Urban development changes how rainfall and snowmelt move through the landscape, increasing runoff while limiting the water available to trees and planted areas.
Low Impact Development (LID) brings water management back into the landscape. Bioretention tree pits use soil, vegetation and engineered infrastructure to capture and manage runoff at source, helping improve water quality while providing valuable moisture for urban trees.




Effective bioretention starts with understanding how water will enter, move through and leave the system. Soil, storage, drainage and tree requirements all need to work together within the wider site strategy.
Trees can form an active part of urban stormwater management when the below-ground environment is designed around both hydraulic performance and tree health.
Our integrated systems combine soil volume, stormwater capture, storage and drainage within a coordinated tree pit, helping project teams make better use of water within constrained urban environments.
Create structural, uncompacted soil volumes beneath sidewalks while providing space for roots and water.
Capture, filter and manage surface runoff within an integrated tree planting system.
Canadian municipalities are increasingly looking for ways to manage stormwater closer to source while creating greener, more resilient public spaces. These projects demonstrate how trees, soil and water management can be incorporated into the urban landscape.
Planning a streetscape, park, LID retrofit or development? Our Canadian team can support stormwater strategy, tree pit design, soil volume, system specification and technical coordination from early design through construction.
