Environmental Services is designing a project to replace an outfall pipe that carries stormwater runoff from 24 acres in southwest Portland and from portions of Interstate 5. The 36-inch concrete pipe collects runoff near SW 35th Drive close to Barbur Boulevard and the freeway and discharges stormwater to Falling Creek, a Tryon Creek tributary.
Over the years, erosion has undercut the pipe where it drains to the creek. This project will replace the outfall pipe, stabilize slopes around and below the pipe, and replant the area with native vegetation.
The project is currently in design and Environmental Services will schedule construction in 2014.
