Alternatives and Level 1 screening
We have completed an initial screening of many different options to replace the terminal based on suggestions community members shared with WSF over the past several years. We developed 15 alternatives, including two alternatives in Elliott Bay, two alternatives in the Burien/Des Moines areas and 11 alternatives in the Fauntleroy area.
Known as Level 1 screening, the goal was to narrow the range of alternatives to a reasonable set of alternatives that could be studied in more detail. WSF evaluated how well each alternative met the project’s purpose and need and other key considerations.
To determine which of the 15 alternatives would move forward in the screening process, WSF applied the following criteria:
- Ability to meet requirements for structural reliability.
- Ability to accommodate projected sea level rise.
- Ability to improve operational efficiency (i.e., minimize dwell time, process vehicles more efficiently, maintain on time performance).
- Ability to reduce the number of conflict points between traffic modes (safety for people driving, walking and biking).
- Ability to meet operational requirements (186 vehicles on the dock or in upland holding, access and maneuverability for an Issaquah class ferry, connection to a minor arterial).
- Ability to keep current sailing schedule (number of peak departures and crossing times).
- Ability to enhance multimodal connections, connect to transit and/or allow for growth in walk-ons, bicycles and vanpools.
- Ability to avoid changes to parks and recreational areas (Sections 4(f) and 6(f) of the U.S. Dept of Transportation Act regulations and projects funded by the Recreation and Conservation Office (RCO)).
- Ability to avoid changes to traffic circulation on local streets near ferry terminal.
- Project cost (design, planning, right of way, risk, construction).
- Alignment with current project schedule.
- Project feasibility—amount of additional right of way needed beyond existing terminal footprint (for expanded footprint, utilities, or construction).
- Permitting and coordination (level of coordination with Tribes and other partners, permitting complexity).
- Changes to existing policies and regulations that risk project delay.
Results of alternative screening
This table is a summary of Level 1 screening results. The green boxes indicate a high likelihood that the alternative could meet the criteria, the yellow boxes indicate a moderate likelihood that the alternative could meet the criteria, and the orange boxes indicate little to no likelihood that the alternative could meet a given criteria.
Alternatives with more than three red boxes will not advance to Level 2. Alternatives A through C are advancing to Level 2 for further analysis and refinement.

Alternatives not advancing to Level 2 screening
Based on the results of Level 1 screening, the following alternatives do not meet several core elements of the project purpose and need and WSF will not be advancing them for further study.
- Moving the Fauntleroy ferry terminal outside of West Seattle drastically increases sailing times and decreases frequency of sailings reducing the amount of ferry service to Vashon Island and Southworth.
- Moving the terminal to South Lincoln Park or Lowman Beach requires purchasing more right of way, reconfiguring local streets to create ferry access and provides fewer connections to transit. Both options would have impacts to parks which require more extensive permitting.
- Bringing an additional 3 million riders per year to Colman Dock slows ferry service for all riders and would require extensive coordination.
- Factors at Southwest Elliott Bay, Burien, and Des Moines locations would increase overall project cost, affect schedule, and require extensive permitting and coordination with multiple partner agencies.
WSF does not plan to advance the following alternatives to Level 2 screening:
