North Seattle Sidewalks

June 28, 2019

What's happening now?

As soon as Monday, July 8 crews will begin building new sidewalk along the south side of NE 110th St between NE 40th St and Sand Point Way. This work is the first step in completing a series of sidewalks in north Seattle. Construction for the entire project is expected to last through the end of the year and is weather dependent. Each street will take approximately 4-5 weeks to complete.

Project overview

This sidewalk project includes a series of 8 new sidewalks that will be installed in north Seattle. These segments have been identified as priorities for pedestrian improvements within the Safe Routes to School and Sidewalk Development Programs.

New north Seattle sidewalks to be installed as soon as summer/fall 2019:

  • NE 95th St between 1st Ave NE and 5th Ave NE (South side)
  • NE 98th St between 5th Ave NE and 8th Ave NE (South side)
  • Meridian Ave N between NE 115th St and NE 117th St (East side)
  • NE 115th St between Roosevelt Way NE and 12th Ave NE (North side)
  • 12th Ave NE between NE 117th St and Pinehurst Playground (East side)
    [Natural Drainage Systems (NDS) will be installed as part of the 12th Ave project]
  • NE 110th St between 34th Ave NE and 35th Ave NE (North side)
  • NE 110th St between NE 40th St and Sand Point Way (South side)
  • Greenwood Ave N between N 97th St and N 104th St (West side)

  • New driveway aprons
  • New parking configurations

Natural Drainage Systems

Natural drainage systems (NDS) are a type of green stormwater infrastructure system (GSI) built to capture runoff and filter pollutants. An NDS uses specialized plan species and soils to filter stormwater runoff and pollutants. Plants are selected to help the NDS do its job: clean stormwater and allow it to slowly seep into the ground. 

The images below show an example cross section of the new sidewalk and natural drainage system. The project design may include elements shown in the cross section and varies by location.

What are the benefits of natural drainage systems?

  • To help manage stormwater flows in your neighborhood.
  • To provide street trees, plants, calming traffic, and reduction of flooding in your neighborhood.

What can I expect after construction?

Because natural drainage is built with growing plants, the way they look will change over time, and take up to two years to fully develop. The grasses, shrubs, and trees installed during construction will grow and change as the garden matures.

When natural draingage systems are installed in the City right-of-way, this may result in some loss of on-street parking, change sightlines, or require mailboxes and other elements within the public right-of-way to be moved.

Who will be responsible for the maintenance of the natural drainage system?

Seattle Public Utilities is responsible for the watering, weeding and general upkeep of the natural drainage systems to ensure proper function. Residents are not required to pay for or perform any maintenance. In fact, it is important for residents to stay out of the NDS areas, so they maintain their function.

Example of what a Natural Drainage System with plants would look like.
