Recommendations

Gehl: “It feels crowded when the sidewalk flow reaches 12 people per minute per yard.”

​

Conclusion: Lowering congestion is not a high priority at this time, except in one case.

​

Goals: Improve the experience of walking for pedestrians by activating spaces

​

    • Benches and tree cover for medians
    • Murals
    • Street vendors on wider sidewalks
