Case Study Project Outcomes

Adequate traffic capacity

Nearby streets receive increased traffic during peak hours

Adequate traffic capacity

Increased travel times for some motorists

Community involvement and local job creation

Rezoning may adversely impact local job market by eliminating Industry

Improved pedestrian and bicycle amenities

Design issues at some intersections

Increased property values and tax revenue

Diminished parking supply

Improved pedestrian and bicycle amenities

Underutilized by pedestrians

Increased neighborhood investment/development

Displacement of businesses and longtime residents

Increased neighborhood investment/development

Project did not provide low income housing

Increased neighborhood investment/development

Development may cause gentrification

Complete street serves multi-modal needs

New housing developments emerged within site

Green space created on site of former freeway

Takeaways These case studies illustrate how future projects can encourage substantial investment in the area and support local businesses. Boulevards can provide adequate traffic capacity and meet the needs of cars, pedestrians, and cyclists.
