Join Stormwater Queensland and event partners Citygreen as we discuss how Street Trees can enhance the liveability of a city and the key considerations to factor into design, application and ongoing management.

Comprising keynote presentations from leading experts, this session is an invaluable opportunity to further your knowledge and skills.

Sessions include:

Street trees changing role in the liveable city Lyndal Plant, Urban Forester

  • Street trees as multifunctional green infrastructure
  • Local government directions e.g. prioritising greening/cooling, canopy cover targets, urban forest resilience planning

Design requirements for optimum tree growth – Ben Gooden, Citygreen

  • Target shade cover and asset values, against projected time scales, enabled by correct soil volumes/spec, water balance and species selection
  • Soils Under Pavements Trials at Bartlett Labs, Charlotte NC, USA

Modelling passively irrigated trees – hydrology and pollutant removal – Sally Boer, E2Designlab

  • How to model passively irrigated trees in MUSIC
  • Applying the sizing guides: retrofit and greenfield case studies

Observations of the design and performance of passively irrigated street trees – Tim Davies, Environmental Engineer

  • Observations and lessons learnt from different designs of passively irrigated street trees without underdrainage.
  • Summary of programs including design considerations, monitoring and costs.

At Citygreen, we love trees. In fact, we think they hold the key to better cities – and a better world. Informed by years of comprehensive research and development, our urban landscape solutions offer the very best in cutting-edge technical design. Not only are they the strongest available by far, our structural modules are also the greenest – made from 100% recycled plastic – evidence of our commitment to the environment.

We want sustainable green space to be within reach of every person, every day – and we’re on a mission to make it happen. We hope you’ll join us on the journey.


Dr. Lyndal Plant is an urban forester who has worked in local government policy and strategic planning for urban trees, including many years with Brisbane City Council. A Churchill Fellow, member of TREENET management committee and now a published researcher and consultant, Lyndal has helped advance urban forest evidence gathering techniques and make stronger business cases for investment in green infrastructure. Lyndal now focuses on policy development/review and cutting-edge urban forest initiatives. She sees the forest, not just the trees – helps plan and monitor outcomes, not just outputs and is committed to greener, cooler neighbourhoods for all.

Ben Gooden is the CEO of Citygreen – innovating with sustainable urban landscape solutions, including tree vault systems, water harvesting and aeration systems, for enabling faster canopy growth. Working with most major cities  in Australasia, USA and Canada, and property developers.

Sally Boer is a founding Director of E2Designlab. Her professional career has been devoted to using science to guide strategic planning and design to inform decisions that shape the creation of healthy and sustainable cities. With a background in freshwater ecology and over a decade of working with developers and local government authorities in urban water management, Sally understands the drivers and sometimes competing interests shaping on-ground outcomes. She has contributed to advancements in passive irrigation approaches and has helped successfully deliver the first large scale open space turf wicking bed in Gladstone and more recently a wicking lawn and self-watering tree for Innovation House 2.0. She also led the tree pit soil moisture modelling for Healthy Land and Water which has provided passively irrigated tree pit design guidance for six climatic zones across Queensland.

Tim Davies is an Environmental Engineer with a passion for creating resilient and regenerative landscapes. Through coupling whole systems thinking with a creative edge, he aims to be a driver of innovation and integration. Tim enjoys working at multiple scales from strategic planning to design to practical hands on landscaping and gardening.

Tim’s experience has given him a deep understanding of the planning, design, maintenance and operational aspects of Water Sensitive Urban Design. Recently, he’s been involved with several projects trialling the use of passively irrigated street trees and the rectification of bio-retention systems to reduce maintenance, improve public engagement and vegetation resilience.
