Study says Portland is a national leader in green stormwater infrastructure system

Over the past few decades, Portland has built one of the most extensive green stormwater infrastructure systems in the country. Instead of relying only on pipes and drains, it has created thousands of rain gardens and green streets to help keep sewage out of the Willamette River. Much of that work has not only involved city engineers but also local community members — from volunteers who ‘adopt’ and maintain storm drains to nonprofits that rip out pavement and replace it with trees and plants. A new study in the journal Sustainability looks back at the first 30 years of Portland’s green stormwater infrastructure, but questions remain about whether the city is keeping up with climate change and rapid growth. Our guests are study co-author Adrienne Aiona, a civil engineer at the city's Bureau of Environmental Services and Ted Labbe, finance and partnerships manager of the nonprofit Depave. They join us to talk about the city’s work and the role of local stewardship in keeping Portland’s green stormwater system alive and well.
