The purpose of this Complete Streets guide is to provide King County jurisdictions with the information and tools to develop, adopt and implement Complete Streets ordinances and street designs. At a time when public health, environmental degradation, livability and economic concerns are at a forefront in cities across King County (and throughout the United States), Complete Streets provides a unique opportunity for communities to address many of these issues. Complete Streets can provide communities with a framework for utilizing public streets in ways that encourage people to walk, bike and take public transportation—all of which have positive implications for health, the environment, quality of life and local economies.
