Project History

Neighborhood Block Meetings – August 2014

In August 2014, the project team met with each proposed project area block to discuss the planting palettes and take input on concepts for the block and individual rain garden locations.

Project Area Blocks Identified – January 2014

Thanks to everyone who has provided input to site and plan the Ballard Natural Drainage Systems (NDS) project. Your input will help to make sure we design and build the best project possible.

In 2014, we will continue investigating underground utilities and soil conditions at the preferred garden locations and gather input about the design, including specific locations for rain gardens, access points to your home, preferences for plant palettes, and other design issues.

Walk and Talk on Your Block – September 28-29, 2013

We walked around with residents of these blocks in September 2013 to gain specific information about trees, plantings, parking concerns and other important information.

Summer 2013

Over the summer of 2013 we visited Ballard neighbors several times door-to-door to gather input from residents on these blocks. We’ve heard and recorded concerns and comments about trees and plantings, parking, and many other things important to residents and property owners. Thanks to everyone who has taken the time to share information with us. The project team is receiving valuable updates every week from Ballard residents and it’s helping us to develop options that address resident concerns.

Phase 1

The project to construct natural drainage (roadside rain gardens) began in 2009. The Phase 1 rain gardens were installed in the public right-of-way between NW 65th Street and NW 80th Street and 28th Avenue NW and 31st Avenue NW in Ballard. See the Phase 1 project map (pdf).

Rain gardens are designed with carefully mixed biorentention soils and densely planted vegetation, to infiltrate and filter stormwater flowing from the sidewalks and roadway, while also providing attractive landscaping. Rain gardens are located within existing city-owned 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 Your block may be considered for a future project.
