About Green Streets
Information
Green streets reduce sewer overflows and backups by slowing and absorbing stormwater runoff from sidewalks and streets. Also known as rain gardens or bioswales, green streets are important to the City’s sewer and stormwater systems. They also help prevent pollution from washing into our rivers.
About Neighborhood to the River Grants
Information
Neighborhood to the River grants are available for projects that improve stormwater management and watershed health while benefiting and involving communities.
About Our Sewer and Stormwater System
Information
Portland’s sewer and stormwater system includes pipes, pump stations, and treatment plants. It also includes green street planters, rain gardens, and trees. Together, this “grey” and “green” infrastructure helps us manage sewage and stormwater to protect people, property, and our environment.
The Percent for Green grant program is open to community groups who would like to complete large-scale green infrastructure projects that provide broad benefits for watershed health and the community. Projects usually take about two years to complete.
