Buildings placed on certain sites may completely block the most desirable street openings and may affect the grades best suited for other parts of the tract...One such building has been recently undertaken on the northwest side of the present driveway where it bends eastward to join the old Boulevard Lafayette at 158th Street...Unless early action be taken by the Board of Estimate, this building will be erected facing the handsome and superior types of buildings on the east side of the drive, and it will stand across the line of 157th Street...

Fifteen feet of sidewalk in front of Cragmoor Dwellings, a ten-story apartment house on Riverside Drive, near 157th Street, fell in last night, having been undermined by a leaky water pipe.  Employees of the Water Department earlier in the day shut off the water in the pipe which led to the apartment house, the only building in the block.
