North Highline Urban Design Standards

The North Highline urban design standards implement the vision of North Highline residents for their community’s future as described in the North Highline Subarea Plan. The standards regulate the development of commercial, mixed-use, and multifamily projects, ensuring that they are appropriate to the community in the following ways:

  • Development is based on an understanding of the physical and cultural context of the neighborhood and the North Highline subarea
  • Development prioritizes compatibility with the existing scale of the neighborhood, walkability, and generous landscaping
  • Development results in a streetscape that is attractive and comfortable for moving through the neighborhood and spending time in it, reflects the character of the neighborhood, and supports neighborhood activities and businesses
  • Development keeps the neighborhood’s diversity visible and promotes distinctive, unique designs through architectural features, signs, art, landscape, and amenities such as seating, lighting, and ornament
  • Stormwater and landscape designs connect the urban environment to the natural systems with designs that are both functional and beautiful
