We teamed up with Rooted in Rights to create a video to educate contractors and other people working in the right-of-way on the importance of maintaining a safe space for people to travel through construction sites. These tips aren't only useful for wheelchair users, they make sites safer for everyone!

  • Title 23 of Seattle Municipal Code dictates that certain types and sizes of development projects require that additional improvements be made to the right of way. These may involve direct improvements to the street, sidewalk, and/or planting strip, or installation of public utilities to serve the area.
  • Others choosing to voluntarily install street improvements will also need to obtain a SIP prior to improving the public right of way

When Title 23 requirements are triggered, required street improvements may include, but are not limited to, installations such as new street pavement panels, new sidewalks, or plantings.
