The road width's not good, but I'd say the bigger problem especially with Lombard is that it's so barren on the sidewalk. I'd guess more than half of the street-level property on Lombard between President and Light is either some form of parking or an inactive side of a commercial property. Two-way the road to slow down traffic or put 10' of sod and some trees to take away a lane in front of each sidewalk and it's still bleak.

All that said, I don't have any ideas for how to make the harbor a more functional neighborhood or welcome pedestrian experience, but I think any efforts to redirect rather than reduce vehicle throughput should be treated with great skepticism.
