Wide street

Wide street is a defined term (§ 12-10): a street whose mapped width meets or exceeds the Resolution's threshold. The width in question is the mapped width of the street — the legal corridor shown on the City Map — not a measurement of the pavement. Avenues and major crosstown streets are generally wide; most side streets are narrow.

The distinction does quiet work throughout the bulk rules: many district tables key their rows to it, assigning wide-street frontages more generous ceilings, higher base heights, or different envelope parameters than narrow-street frontages in the same district. Misreading a lot's street status is a standard way to quote the wrong maximum, which is why serious analyses verify it rather than eyeball it.
