Technical Memorandum Review 4 Technical Memorandum 3.2 – Goals and Objectives Technical Memorandum 6.1 – Goals and Objectives 4

TM 3.2 – Goals and Objectives 5 Alignment Evaluation Criteria Mobility Local Access Safety Traffic safety, Pedestrian safety Bicycle safety Emergency vehicle access Impacts to Natural Environment Impacts to Built Environment Land Use Compatibility Flexibility of Implementation Cost Effectiveness 5

TM 3.2 – Goals and Objectives 6 Streetscape Evaluation Criteria Aesthetic Enhancement Environmental Features Multi-Modal Safety Maintenance Functionality 6

TM 6.1 – Design Criteria 7 7

TM 6.1 – Design Criteria Design Element Design Criteria Travel Lane 8 Design Element Design Criteria Travel Lane 10 ft – 14 ft Turn Lane 11 ft – 14 ft Shoulder 6 ft (min.) Bike Lane 6 ft Median Width 4 ft – 16 ft Shy Distance (where app) 2 ft 8

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

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

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

Horizontal Alignment Maximum degree of curve based on speed

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

Roadway Profile Sight distance requirements Vertical curve design

Roadway Cross-Sections Lane width requirements Travel lane – 11-12 feet Center turn lane – 12-14 feet Bike lanes – 6 feet on both sides Sidewalks – 6-8 feet Landscape strip – 5-7 feet Source: City of Happy Valley TSP

Roadway Cross Sections Typical 3-lane arterial roadway Source: City of Happy Valley TSP

Other Streetscape Features Drainage considerations

Other Streetscape Features Retaining wall to minimize impacts

Streetscape Examples SE 172nd Avenue (South of Sunnyside)

Streetscape Examples SW Walker Road

Streetscape Examples SW Kruse Way

Intersection Options Traffic signals Roundabouts Stop signs

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

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

Future Transportation Conditions -- 2035 25 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)

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

Topography

Natural Resources

Existing Cross-Section 172nd Avenue

Existing Cross-Section 190th Avenue

Other Opportunities and Constraints 10 historical resources eligible for National Register of Historic Places Generally located along Foster Rd No recorded archaeological sites

Overview Of Concepts From WS #2 (See Handouts) 36

Now Let’s Create Some Corridor Design Concepts… Use the Roadway Design Tool to sketch new road alignments on the base maps.

Upcoming Meetings and PMT Roles PAC #3 (December 1, 6-9 p.m.) Workshop #3 (December 8 , 6-9 p.m.) PMT Roles Attend both meetings Listen to public comments Provide staff perspective, as needed.
