1. Upstream / downstream distance to intersection. See Figure 2.23.
2. If both mailboxes are located between two driveways, those driveways can be exactly 10 feet apart. If they are more than
10 feet apart, they must be 20 feet apart or more.
F. Driveway Spacing
1. Spacing between driveways is measured along the property line from the edge of one
driveway to the closest edge of the next driveway.
2. Table 2.10 defines minimum driveway spacing as a function of thoroughfare classification.
3. In the vicinity of a railroad crossing, the closest edge of a driveway shall be a minimum of
one hundred feet (100’) from the railroad ROW line.
4. Non-residential and multi-family driveways on opposite sides of an undivided street shall
align with each other or be spaced a minimum of seventy-five feet (75’) apart, measured edge
to edge, to ensure that conflicting movements do not overlap. This spacing shall also apply to
a driveway that is on the opposite side of an undivided street from an intersecting street. See
Figure 2.22.
