E 650 Borders

The term border, as used by AASHTO, (designates)¹ is the area between the edge of the roadway pavement and the property line the right-of-way line that separates traffic from adjacent homes and businesses. This terminology is used to avoid the confusion created by the dual use of the word parkway, which is often used to define the above area as well as the unpaved or planted area between the back of curb and the front of sidewalk.

For a minimum section in a residential area, or any contexts where pedestrians are present or expected in the future, the border area should include sidewalk and a buffer strip between the sidewalk and curb. Transit stops, loading zones, and other facilities and features serving pedestrians and bicycles may also be placed in the border area.

The requirements for the rounded or diagonal cutoff property lines at each block corner are included in the following discussion since the area provided is considered part of the border area.
