Safety Concerns & Enhancements

2

Intersections

• Poor sightlines• Insufficient lane/shoulder width• Disconnected trail network

• Poor drainage system

• Poor pedestrian connectivity• Non-existent sidewalk or crossing

facilities

• Insufficient lanes for growth• No medians or traffic islands• Significant queues / heavy traffic

congestion • Sharp vehicle turning movements• Short acceleration lanes• Unsignalized intersections• Parking conflicts• Unconventional merging• Poor visibility

• At-grade crossings blocked• Unsafe turning movements• Insufficient crossing

signals/signage

Existing Safety ConcernsBefore

Before

After

Before

• Reduced interaction between motorists and railway operations

• Improved cross‐ sectional design on Low Level Road

• Improved roadside design

• Improved pedestrian and cyclist facilities on (or near) the corridor

Safety Audit Improvements

After

Spirit Trail Pathway

Woodland Suspension Bridge(before)

• Very low sightlines

• Narrow creek crossings

• No illumination

• Unstable slopes • Dense vegetation• Poor drainage

Existing Safety Concerns

Before After

After

Low Level Road Corridor

• Eliminated 3 at-grade crossings

• Added vehicle overpass • Widened intersections

• Multi-tier retaining system for safer road/rail corridor

• Improved slope stability & landslide mitigation

• Upgraded power connections & utility relocations

• Integrated multi-modal transportation corridor

• Added street lighting• Trail connections• Improved access• Enhanced intersection

Envision® Overview3

Where we have been: Multiple Rating Systems

Building Scale (e.g. LEED®)

Where we are:Infrastructure Project Scale (Envision™)

Where we are headed:City-Scale sustainable

planning

Evolution of sustainable design

Envision™ provides a holistic framework for planning, evaluating and rating the community,

environmental, and economic benefits of all types and sizes of infrastructure projects…
