As cities face increasing climate pressures—from prolonged droughts to sudden flash floods—urban trees have become essential assets in creating resilient, liveable environments. Yet, existing tree pit designs often fall short of supporting long-term tree health, fail to manage stormwater effectively, and can contribute to costly damage to pavements and infrastructure due to uncontrolled root growth.
We seeking innovative design solutions from the industry for a new generation of urban tree pits that can support healthy tree development in increasingly challenging urban conditions. These systems should be capable of accommodating natural root expansion without damaging surrounding infrastructure, while ensuring access to sufficient nutrients and water. Designs must also integrate the capacity to absorb rainfall—particularly during heavy downpours—to reduce surface runoff and
alleviate pressure on stormwater systems. Additionally, we are interested in features that allow for both passive irrigation and community-supported watering practices, reinforcing civic engagement and long-term tree care.
