5. Existing Federal Way Historic Oregon Trail US 30 Two-Lane Roadway Substandard

6. Ongoing Growth ITD Relocated US 30 to I-84 ACHD assumed responsibility Traffic increases Need improvements

7. Project Constraints Higher than state average accident rate Need 2-Lanes each direction One side developed Canal and bench along other side Widen Roadway in Constricted Space

8. Roadway Alternatives Meeting – January 1992 –5 lanes –One-way couplet –4 lanes –No-build Alternative Modes Meeting - May 1992 –Bike path alternatives –Vista turnouts –Landscaping Public Involvement

9. Public Support Public Hearing December 1992 Supported safer 5-lane section Landscape Vista turnouts Bike Path

10. Project Development Original 3 Mile Project split into 3 projects Additional 2 Miles Designed Total of 5.2 miles –5-lane section –Vista turnouts –Bike Path –Landscaping

12. Federal Way Constructed Project Pathway Street lighting Landscaping Scenic overlook

17. Lessons Learned Consider non-traditional design approaches Actively involve stakeholders during the design process Balance stakeholder input with prudent design Budget for additional time and expenses during design and construction Maintain constant communication with stakeholders

19. Project Objectives for Success Comprehensive collaboration Maintain flexibility Timely decisions Assure NEPA compliance Stakeholder support Deliver Phase I (Bellgrove to Mica) to construction in 2001

20. Context Sensitive Solutions Approach Formal Design Partnering Process Address Transportation Needs Collaborative communications Structured decision process Encourage creativity and innovation in design Assure NEPA compliance

25. Selection of Alternatives Initial range of alternatives Establish study corridor Identify constraints for entire corridor Evaluate and Screen alternatives by segment Select reasonable alternatives Identify preferred alternative
