South Park Sewer Improvement

What & Why

Seattle Public Utilities (SPU) has installed a new pipe and drainage structures to increase capacity for stormwater and sewage, and reduce flooding in the South Park neighborhood. The new pipe runs under 14th Avenue S, between S Concord and S Donovan streets, and west under S Donovan Street to 12th Avenue S. SPU also installed street improvements along the south side of S Concord Street.

This project was supported in part with funding from the King County Flood Control District.

What’s happening now?

Construction and landscape restoration for this project were completed in 2016.

Project goals and benefits

Added pipe capacity will help relieve chronic sewage backups in homes and businesses and reduce generalized flooding in the area of 14th Avenue South and South Concord Street.
