D. Driveway Width – The width of a driveway refers to the width of pavement at the property line
and is measured where the curb return radii ends perpendicular to the street curb or edge of
pavement. The minimum and maximum widths of driveways are listed in Table 2.9. A driveway
may transition to a different width as it extends onto the property, but its width shall not change
abruptly at the property line.

faces onto the alley; otherwise, its width is limited to twenty-four feet (24’).
E. Driveway Radius
1. All driveways intersecting dedicated streets shall be built with a circular curb radius
connecting the six-inch (6”) raised curb of the roadway to the design width pavement of the
driveway.
2. Driveway radii shall fall entirely within the subject property so as to begin at the street curb at
the extension of the property line.
3. Table 2.10 presents the minimum and/or maximum standards to be applied in designing and
locating driveways on public streets.
4. High capacity driveways shall meet the same standards as those defined in Table 2.10.
