Here's NYC's ZoLa of this block without the named streets https://zola.planning.nyc.gov/l/lot/1/533/1
Here's NYC Street Map also not listing these streets: https://streets.planning.nyc.gov/?lat=40.728&layer-groups=%5B%22arterials%22%2C%22citymap%22%2C%22name-changes%22%2C%22paper-streets%22%2C%22pierhead-bulkhead-lines%22%2C%22stair-streets%22%2C%22street-centerlines%22%5D&lng=-73.9968&zoom=16.98
Doesn't seem like they are named.
