The Right-of-Way Improvements Manual is one of many resources for a project applicant proposing to do work in the street right-of-way. Information in the Manual is:

• Consistent with citywide regulatory documents such as the Seattle Municipal Code and City of Seattle Standard Plans and Specifications.
• Consistent with applicable federal, state, regional and local regulatory requirements.
• Consistent with related citywide plans, such as the Comprehensive Plan, the Transportation Strategic Plan and Comprehensive Drainage Plan.

Compliance with certain federal standards including the Americans with Disabilities Act (ADA), and the Manual on Uniform Traffic Control Devices (MUTCD) is necessary for all work done in the street right-of-way. The City of Seattle recognizes the Washington State City/County Design Standards as the basic set of requirements for roadway work in the street right-of-way.
