I don't know specific streets but from what I've seen their first due area goes up to about 2nd and 20th, West to around Union Square South, East all the way to the river, and south to around St Mark's. Their second and third due areas cover Engs. 14, 16, 28, AND 33 and I've seen them respond as far north as 1st and 28th (Bellevue/NYU). Someone in dispatch could probably tell you more accurately, I'm just going by what I've seen from living nearby ;D
