What is Street?
A street is any road (other than a private road), highway, parkway, avenue, alley or other way shown on the City Map, or a way at least 50 feet wide and intended for public use which connects a way shown on the City Map to another such way or to a building or structure. A street refers to the entire public right-of-way (including public sidewalks).
A wide street* is a street that is 75 feet or more in width. Most bulk regulations applicable to wide streets are also applicable to buildings on intersecting streets within 100 feet of a wide street.
