twenty or thirty yards

[Maybo]

I reached the end of the alley, looked to my right, and saw him clinging to the second-story cornice of a stone building twenty or thirty yards down the street. He looked like a human fly. I could see the metal gutter he must have climbed to get out of Radar's reach (but not quite quickly enough, ha-ha), and as I watched he scrambled onto a ledge and squatted there.

Does the underlined part mean that the distance (height) between the second-story cornice and the street is twenty or thirty yards?

No. The stone building is 20-30 yards away from the narrator. Down the street.

 

[Maybo]

Down the street.

Does it mean along the street? There is twenty or thirty yards between the narrator and the stone building along the street. Is that correct?

 

[5jj]

It is.
