Project History
The project to construct natural drainage (roadside raingardens) began in 2009. Drainage swales were installed in the public right-of-way across 10 city blocks between NW 65th Street and NW 80th Street and 28th Avenue NW and 31st Avenue NW in Ballard. See the project map (pdf).
The rain gardens are designed with soils and densely planted vegetation to infiltrate and filter stormwater flowing from the roadway, while providing attractive landscaping. Rain gardens are located within existing planting strips, and, in some cases, may extend slightly into roadways.
If you live in Ballard and would like to explore the possibility of having a roadside rain garden installed by the city, please send your name, address, phone number and email address to the project manager at roadsideraingardens@seattle.gov.
