Event description


The link between water and roads is not necessarily obvious but is fundamental to the management of both. With stormwater being a function of land-use, and roads typically being dominated by impervious surfaces and contaminant generating activity, the linkage is strong and therefore synergies with how we tackle the design and management of roads and stormwater can deliver a wide range of benefits.

Unfortunately, in practice, roads and stormwater are often managed in a segregated manner with engineers, planners and designers focused on one or the other but seldom holistically as an integrated system.

To achieve these requires an appreciation and acceptance of disciplinary priorities such as safety, pavement design and hydraulics but through working collaboratively, truly integrated solutions are readily available. Fostering the nexus between water and transport should therefore be actively encouraged to support the broad range of urban outcomes that communities aspire to.

In this highly interactive webinar presenters will discuss:

  • Integration of stormwater treatment into road corridors
  • The use of roads as designed flood attenuation
  • The intentional use of roads as efficient conduits to support the harvesting of stormwater for reuse.

About the presenters

Stu Farrant

Stu Farrant joined Morphum Environmental to establish and manage its Southern Sector branch. Driven by adopting evidence-based innovation in the planning and design of integrated water management solutions, he has a particular passion for the design of constructed wetland systems and has delivered numerous successful projects at a range of scales.

Stu is an ecological engineer who specialises in the water aspects of ecologically sustainable development, particularly integrated urban water cycle management and water sensitive urban design (WSUD), and he has extensive skills in the planning, design and implementation of innovative and practical water management projects.

Alan Gregory

Alan is Principal Transportation Planner at Tonkin and Taylor.

He is a engineer with over 20 years experience in strategic road networks and project management. He has extensive experience in the development and management of roading networks, accident remediation, safety improvements, transport strategy and traffic management.

Ed Clayton

Ed is an Environmental Science Service Leader at Pattle Delamore Partners in Auckland. His background is in technical hydrological monitoring, installing and operating networks of remote monitoring stations and urban freshwater studies. Lately, he has been involved with monitoring projects that are supporting the Safeswim and Safe Networks projects in Auckland. His professional interest lies at the intersection of urban transport systems and freshwater, how people value and interact with water and the changes we need to make to ensure a sustainable urban freshwater resource.


This webinar is part of a series cohosted by The Sustainability Society and the Transportation Group, and supported by EngineeringNZ, to stimulate discussion and knowledge sharing across a range of sustainability issues within the transportation arena. This series is relevant not only to transportation professionals but to the wider built environment and urban planning community where considerations of movement, accessibility and resilience are crucial to taking a system-wide integrated approach to our cities.

More sessions announced soon for early 2019.
