Factors considered in the public involvement process and Board deliberations include:

• The package provides funding for expanding access to many of Sound Transit's busiest facilities, as well as new facilities. This includes funding for new parking as well as other access improvements.
• Planning for increased parking is based on projections of future parking demand balanced with community needs and accessibility. It is difficult to provide more parking at some very popular park-and-ride lots because of constrained land area, access and traffic issues or sensitive adjacent land uses.
• The system access plan will work with communities to determine the right mix of additional parking, bus connections, passenger drop-off space, walking or biking access or combinations of all of these things.
• Where many people and jobs are not located within walking distance of stations or local transit services cannot meet demand to stations, parking facilities are an effective way to attract riders to the stations from larger surrounding areas.
• Sound Transit tries to reduce demand for station parking by working with local transit partners to integrate regional transit services with local transit services.
