Argay Green Street Project

Updated August 3, 2017

Environmental Services has completed the design of a stormwater management project in the Argay Terrace neighborhood in northeast Portland. When it rains, water flows over streets, drains into the stormwater system and flows to the Columbia Slough. This project will build 53 green street planters (see map below) next to sidewalks. The planters will filter the stormwater before it enters the slough, helping to protect water quality and control stormwater runoff during heavy rain events. Construction is expected in September 2017.

Green Streets

Green streets are rain gardens that collect stormwater runoff from streets and allow 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 1,600 green street planters across the city that manage stormwater, reduce sewer backups and add green space in neighborhoods. Go to to see green street examples and get more information.

Environmental Services locates green street planters where they will be most effective in keeping stormwater out of the sewer system. The planters in this project will be curb extensions, extending into the on-street parking zone next to the curb.

Environmental Services has communicated with adjacent property owners where proposed green streets will remove on-street parking spaces.
