Environmental Services is nearly finished designing a green street project along NW Front Avenue near NW 26th Drive to manage stormwater runoff. Three green streets will help to remove suspended sediments and slow the flow of stormwater into the adjacent city storm system. Green streets also add green space to neighborhoods.
Environmental Services uses green streets throughout the city to help manage stormwater and protect water quality in our rivers and streams. This project will pilot planter designs meant to manage stormwater runoff from the public right-of-way in areas with surrounding industrial uses.
The green street planters will extend into the right-of-way to capture the highest volume of stormwater. Existing sidewalks and pedestrian amenities will be maintained, although some existing parking spaces may be removed. The planters will be designed to collect stormwater runoff from the adjacent right-of-way into vegetated planters. This will allow it to slow and settle, removing suspended sediments before it is discharged to the storm system.
Construction could begin as early as September 2016. Each planter will take several weeks to construct, although work may take place in phases and there may be delays between phases. We will continue to provide you information as the project gets closer to construction.
