Transportation Planning
How Transportation is Planned
Transportation planning involves long-range plans as well as a framework for making projects happen. The guiding document is the Sammamish Transportation Master Plan (TMP) which provides transportation goals, policies, and implementation strategies over a 20-year period.
The City also develops mode specific plans that complement the TMP such as the Bicycle and Pedestrian Mobility Plan and the Transit Plan.
How Improvements Are Made
The City’s Transportation Improvement Plan (TIP) is the framework for how projects are evaluated and considered for programming over a six-year period.
Please visit the TIP page for information on project programming, or the Capital Improvements page for status updates on specific projects that are underway in Sammamish. (Note that the TIP will be incorporated into the Capital Improvements Plan in 2025.)
The Traffic Engineering page includes information about how the City monitors, operates, and maintains intersections, streetlights, and road markings in Sammamish.
How the City Keeps a Growing Community Moving
City planners, development review engineers, traffic engineers, stormwater engineers, inspectors, and maintenance teams review development applications to manage impacts to Sammamish’s transportation and rights of way during and after construction:
- Codes & Standards: New applications must meet city codes and standards, state and federal laws
- Frontage Improvements: Roadway width, sidewalk, bike lanes, lighting, curb, landscaping
- Traffic Impacts & Mitigation: Both immediate vicinity and greater transportation system
- Access Design: Sight distance, lane configuration, driveway grades
- Use of Street & Right-of-Way: permitting and inspections during construction
How to Get Around Sammamish
Transportation mobility is all about meeting the community’s needs for getting around. The City partners with a variety of transportation providers for shared transportation options including bus service, the park-and-ride, Community Van, micro-transit service, and school district transportation services.
