If that is St. Louis Cathedral, then this, being the "northwestern" (upper in N.O. parlance) side, would be St. Peter Street. St. Peter Street extended far beyond North Rampart until the Treme neighborhood was raped in the construction of Armstrong Park in the early 70s, cutting the street for several blocks. The fenced off area to the right is the Carondelet (or Old Basin) Canal, which was no longer navigable by 1935 and filled in in 1938.
Fence on right would be for the Southern RR and for the GM&O Railroads. Street would be Toulouse, maybe. Those houses were still there at the time of the storm in 2005.
