Environmental Services has completed construction on a project to add three rain gardens along Sandy Boulevard, between SE 8th and 9th and Oak and Stark Streets. This new green infrastructure manages runoff from about 1.5 acres of roadway and removes about 1.3 million gallons of stormwater a year from the sewer system. These stormwater facilities help preserve the capacity of the sewer system, protect the city’s investments in sewer improvements, and protect public health, property, and the environment.
In addition to managing stormwater runoff, the project:
- Improves pedestrian and bike safety
- Improves traffic circulation around the intersection of SE 9th and Sandy
- Supports the efficient movement of freight traffic within the project area.
Environmental Services worked with the Central Eastside Industrial District’s Freight Committee and Portland’s Bureau of Transportation to design the travel lanes.
Converting about 8,500 square feet of asphalt along Sandy into landscape areas added neighborhood green space, improved the urban environment, and increased parking spaces. Large trees along Sandy contribute to both stormwater management and aesthetics. The project added four parking spaces and restored eight parking spaces removed when the city implemented the parking permit system.
Nearly $350,000 in grant funds from Portland’s East Side Big Pipe Community Benefit Opportunity Program and the US EPA’s Integrated Wet Weather Program helped fund this project.
The green streets in this project collect stormwater runoff from streets and allow the water to soak into the ground as soil and vegetation filter pollutants. The city maintains green streets to ensure that they effectively manage stormwater. Portland has more than a thousand green street planters that manage stormwater, reduce sewer backups and add green space in neighborhoods.
