In Buffalo, New York, the frost line typically reaches depths of about 36 to 42 inches (91 to 107 cm). This depth can vary slightly depending on specific local conditions, such as soil type and moisture levels. It's important for construction and landscaping to consider the frost line to prevent damage from freeze-thaw cycles.
USA Today published the following pdf file that shows the frost line of all areas of the USA. http://www.soundfootings.com/pdf/US_Map_Frost_DepthAVG.pdf This shows that the great city of Buffalo, New York has a frost depth of 35 inches. I have heard of depths up to 48 inches for Buffalo. South Buffalo is always a bit warmer and friendlier.

Up to July 2008 it was 4' per the NYC Code. I haven't dealt enough with the newly adopted code. I imagine it hasn't changed.
Average is 4ft, building code requires water pipes to be at least 6ft deep to be well below frost line and safe from frezzing.
