Green infrastructure (GI) is an umbrella term for infrastructure that delivers benefits to urban development through the ecosystem services that natural systems provide. GI's benefits include reducing the urban heat island effect, improving air quality and beautifying urban spaces, but one of the core design functions of GI is stormwater management. The most common stormwater GI tools are bioretention, bioswales, green roofs, and permeable pavement. The City of Vancouver is in the midst of shifting from GI as demonstration projects to GI as standard practice for both public and private development.

This workshop will begin with an introduction to GI and the drivers for implementing it in Vancouver. Then the City of Vancouver GI design team will delve into the detailed design of a bioretention system using a City of Vancouver case study project. The session will cover geotechnical requirements, sizing methodology, recommended design details, and the importance of soil specifications and planting design to project success. Finally, an overview of other GI tools, such as green roofs and rainwater harvesting, and considerations for how they are implemented in a Vancouver context will be presented.

She also spent nearly 8 years in the Transportation Division, where she developed expertise in community engagement, integrated land use and transportation planning and sustainable transportation.

Robb Lukes, P.Eng.

Robb Lukes is a senior engineer in the City of Vancouver Green Infrastructure Implementation Branch where he has led the development of green infrastructure standards, design guidance, asset management, and monitoring program. Robb Lukes has 15 years of experience in stormwater management policy, planning, design, and construction in both the US and Canada. Robb has a master's degree in water resource management from the University of Wisconsin and bachelor's degree in civil engineering from the University of Portland.

Kristen Hudson

Kristen Hudson is a horticulturist by trade with an academic foundation in urban ecology and a passion for sustainable landscape design. Hailing from the broadleaf forests of the east coast and now residing in the coniferous Pacific Northwest, she offers a unique perspective and deep understanding of native plant communities and the complexities of natural ecosystem functions. Working with the City of Vancouver’s Green Infrastructure Implementation Branch, she aims to harness the technologies of plant systems and healthy soils to clean stormwater, restore natural hydrological cycles, and cultivate biodiverse landscapes. Kristen holds a diploma in landscape design and a Bachelor of Horticulture Science in urban ecosystems.
