Congestion pricing. Eliminate parking for sidewalk space and include delivery zones or dedicated delivery times with the street closed to traffic otherwise.
On street view I see maybe one delivery truck per block. Otherwise a very large portion of the street is dedicated to empty car storage. You've seen delivery zone parking before, right? The entire problem is how much space private vehicles take up versus the amount of public space that is available to people. The imbalance is huge and unfair and it's a matter of when, not if, that balance is going to be adjusted to a reasonable state.
Do you know who pays for congestion pricing then? Manhattanites will. That increased cost of delivery will be passed on to everyone in the form of increased prices.
