9. Corridor Alignment Goals
Improve mobility for:
Through traffic
Local community
Freight traffic
Minimize impacts to:
Environmental resources
Cultural resources
Social
Provide flexibility for:
Changing socio-economic conditions
Development opportunities

10. Streetscape Goals Provide an aesthetically pleasing design. . .
That supports the character of the adjoining land uses
That preserves rural character
Integrate “green streets” design with the natural features
Improve safety for all users
Support healthy and walkable communities

11. Corridor Design 101 Roadway Design Basics Horizontal alignment
Vertical alignment
Roadway cross-sections
Intersection treatments
Intersection spacing

12. Horizontal Alignment
Maximum degree of curve based on speed

13. Vertical Alignment Maximum Roadway Grades 8% for arterial roadways
12% for collector/ local roadways

14. Roadway Profile
Sight distance requirements
Vertical curve design

15. Roadway Cross-Sections
Lane width requirements
Travel lane – feet
Center turn lane – feet
Bike lanes – 6 feet on both sides
Sidewalks – 6-8 feet
Landscape strip – 5-7 feet

20. Streetscape Examples
SW Walker Road

21. Streetscape Examples
SW Kruse Way

22. Intersection Options

23. Intersection Spacing Minimum Intersection Spacing
Arterial & collectors intersections – 1,000 feet
Local street intersections – 500 feet

24. Corridor Opportunities and Constraints
Discussed in
Stakeholder interviews
Memos on existing conditions
Memos on projected future conditions

25. Future Transportation Conditions -- 203525
Projections in Project Study Area
Households grow by more than 300%
Jobs grow by 1,200%
Virtually all intersections fail during peak hours
Projected Average Daily Traffic (ADT)
16,000 vehicles/day (south of Foster Rd)
25,000 vehicles/day (north of Sunnyside Rd)

26. Existing Transportation Conditions
Traffic volumes
172nd Avenue: 8,500 vehicles /day (near Hemrick Rd)
Foster Road : 7,500 vehicles /day (near Cheldelin Rd)
SE Sunnyside Road: 9,000 vehicles /day (near 172nd Ave)
All intersections operate acceptably except Foster Road/172nd Avenue (LOS F)
Intersection crash rates are within normal levels
There are no bike lanes or sidewalks
