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.
Neighborhood to the River grants are available for projects that improve stormwater management and watershed health while benefiting and involving communities.
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.

The City's Bureau of Hydroelectric Power was established in 1979 to supervise the construction and administer the ongoing operation of the Portland Hydroelectric Project (PHP) located in the Bull Run Watershed.
This project will adjust the location of environmental overlay zones in the Columbia Corridor and other industrial areas to match the locations of streams, wetlands, sloughs, vegetation and wildlife habitat.

Portland Parks & Recreation (PP&R) Urban Forestry's mission is to manage and ensure Portland's urban forest infrastructure for current and future generations. Our urban forest consists of 218,000 street trees, 1.2 million park trees, and 2.9 million private property trees.
The City of Portland code requires individual properties to have direct and independent connections to the public sewer. However, the City may accept or adopt a private sewer line in the right-of-way serving residential properties under certain conditions.
