DOT's design standards set target widths based on street classification and expected pedestrian volume, with commercial corridors and wider avenues typically getting more sidewalk width than narrow residential side streets. When a sidewalk is being fully reconstructed rather than simply repaired flag-by-flag, the project may need to match existing width unless a broader streetscape change (like a neckdown) is involved. Width also interacts directly with the clear path requirement, since obstructions like street furniture or a tree pit reduce the usable pedestrian space within that total width.
