The maximum width of any residential driveway at the entrance from the right-of-way shall be 24 feet;
The minimum distance between the centerlines of driveways for lots to be used for any non-residential purposes shall be 110 feet;
The minimum distance between the centerlines of driveway entrances, whether on the same side of the right of way or the opposite side, to lots to be used for any non-residential purposes shall be 110 feet, except for driveways directly across from each other;
The minimum distance between the centerlines of driveway for lots to be used solely for residential purposes shall be 60 feet; and
The minimum distance between the centerlines of driveway entrances, whether on the same side of the right of way of the opposite side, to lots to be used solely for residential purposes shall be 60 feet, except for driveways directly across from each other.
Angle of Intersection. The angle at which a driveway intersects the right-of-way shall be no
more than 90 degrees, but in no event less than 60 degrees.
Grading. A driveway shall slope ¼” to ½” per foot (2% to 4%) downward away from the edge of the right-of-way to the center of the right-of-way ditch line so that the driveway does not drain into the right-of-way, as provided in Appendix I, Road Design Standards and Specifications, of the Land Use Laws and Regulations.
Line of Sight Distance. The all-season safe sight distance along the right-of-way shall be determined by the applicable speed limit on the right-of-way, as follows:
Type of road
Speed limit, or if none, typical speed
Minimal safe sight distance
(a)
Minor roads
30 mph or lower
200 feet
(b)
Through roads
31–40 mph
275 feet
(c)
Through roads
41–50 mph
400 feet
(d)
Major roads
51–60 mph
525 feet
Un-posted roads shall be assumed to have a thirty (30) mph speed limit.
Measuring Line of Sight Distance. The all-season safe sight distance shall be measured
from a point three feet nine inches (3’9”) above the proposed driveway surface and at least ten feet back from the edge of the right-of-way. From this point, the critical line of sight shall be measured in both directions to a point three feet nine inches (3’9”) above the intersecting right-of-way at the distance calculated as above and be applicable for vehicles approaching the proposed driveway from either direction.
