Become a Green Street Steward!


maintaining a green street

Portland is recognized internationally as a leader in sustainable stormwater management. Since 2003, Portland created more than 1,200 Green Streets throughout the city to manage stormwater at the source, where the rain falls. Green streets are small rain gardens that reduce the volume of stormwater and its associated pollutants, keeping it out of sewer pipes where it can end up in our rivers and streams or cause sewers to back up into homes and businesses. 

Through this effort, Portland treats stormwater as a resource, and adds green spaces to neighborhoods. Green Streets also help clean the air, enhance street safety, and protect sewer ratepayers’ investments in the piped collection system.

Community members have asked how they can participate in the care of Green Streets as a way to help the environment and build community. Now, through the Green Street Steward program, community members can adopt a Green Street and work with the city on green street care and maintenance.

The city is still responsible for looking after Green Streets and ensuring they work properly. Green Street Stewards simply volunteer to help pick up trash, remove leaves and debris, and occasionally weed and water green street facilities. Partnerships between the city and community members contribute to Portland’s beauty and enhance livability. Please consider becoming a Green Street Steward as a rewarding way to care for your community and keep Portland’s rivers clean.
