- Connectivity. The plan will provide a network of continuous links connecting employment, retail centers, schools, parks and other primary destinations with the Island's neighborhoods.
- Sustainability. The plan will increase the opportunity for sustainable transportation choices by Island residents by facilitating pedestrian and bicycle movement as an alternative to the automobile.
- Safety. Facilities provided by the plan shall be designed to reduce conflicts between autos, bicyclists and pedestrians, and provide a safe system of facilities for all user groups, especially for children on routes between neighborhoods and schools.
- Routine Accommodation. Street improvements will be designed by identifying the full range of mobility needs to be met by the facility, and then balancing or adjusting these needs with space, financial and other considerations to achieve the best result.
- Arterial corridors are shared-use assets. Automobile, bicycle and pedestrian use must be integrated. These needs should be considered in planning street projects.
- Incremental solutions are preferred. Consideration should be given to the minimal facility or improvement that can balance competing priorities.
- Appropriate facilities balance community values, expected uses, and site. Preserving Mercer Island's woodsy, rural character and neighborhood scale is important.
- The Mercer Ways are a unique and valuable community asset. Trade-offs here are especially complex.
- Maintenance practices, parking and speed control policies (and their enforcement) affect use of these facilities. These issues must be addressed to assure full value is obtained from investments.
How are Pedestrian/Bicycle projects selected?
The City of Mercer Island recognizes and encourages walking and bicycling in the community. In 1996, the City developed a plan which identified specific pedestrian, bicycle, and trail projects. The plan was updated in 2010.
Projects included in the 2010 Plan were developed and ranked based on the following performance criteria:
The City makes an effort to coordinate the development of new or enhanced pedestrian and bicycle facilities with utility and street projects. As a result, major pedestrian and bicycle facility improvements are often constructed in conjunction with other projects.

How are residential and arterial streets selected for improvement?
These rankings are coupled with other planning considerations (such as the water and sewer comprehensive plans and the Pedestrian and Bicycle Facilities Plan), and used to develop the six-year Transportation Improvement Program.
