The design features described herein and the tables with their appropriate illustration of various driveway features as shown in Tables 1 through 5 shall be used by the applicant in dimensioning proposed driveways or driveway systems on plans accompanying driveway permit applications. These standard dimensions will be used unless conditions require a deviation and the applicant can show cause for deviation. The Building and Planning Department reserves the right to determine whether this deviation shall be granted and may specify particular dimensions in order that particular driveway system will accommodate the vehicles normally expected without creating undue congestion or hazard on the road. The letters in parentheses accompanying the following design feature titles are used to illustrate these design features in Tables 1 through 5.
(a) "Intersecting Angle" (A), the clockwise angle from the road edge of pavement or road centerline if unpaved to the driveway reference line (the centerline or edge of the driveway).
(b) "Driveway Width" (B), the distance between driveway edges of pavement (or edges of the gravel surface, if applicable) measured at the point where the edges of the driveway become parallel (point b in the sketches). If the right-of-way line is so close to the pavement that point b falls on the applicant’s property, then the width of the driveway at the right-of-way line shall be based on the projected Driveway Width.
(c) "Entering Radius" (C), the radius of the driveway edge curve on the right side of a vehicle entering the applicant’s property.
(d) "Exiting Radius" (D), the radius of the driveway edge curve on the right side of a vehicle exiting the applicant’s property.
(e) "Curb Ending" (E), the length of the height transition of the driveway curb from ground level to full curb height along an uncurbed road. This curb transition shall be 10 feet minimum.
(f) "Right-Turn Lane Length" (F), the length of auxiliary lane constructed preceding the driveway to accommodate traffic entering the applicant’s property.
(g) "Right-Turn Lane Width" (G), the width of pavement from the outside edge of the through lane to the outside edge of the Right-Turn Lane, or the width of road from outside edge of the through lane to the outside edge at the full width of the Entering and Exiting tapers.
(h) "Entering Taper" (H), the length of the diagonal pavement widening, preceding the driveway.
(i) "Exiting Taper" (J), the length of the diagonal pavement widening, following the driveway.
(j) "Entrance Drive Width" (K), the width of the half of a Divided or a Directional driveway which has been designated for the use of a vehicle entering the applicant's property.
(k) "Exit Drive Width" (L), the width of the half of a Divided or a Directional driveway which has been designated for the use of a vehicle exiting the applicant's property.
(l) "Island Width" (M), the edge-to-edge distance between the Entrance Drive and Exit Drive.
(m) "Island Length" (N), the distance between ends of the island, measured parallel to the Entrance Drive.
(n) "Nose Offset" (P), the distance between the edge of the turn lane or through lane and the traffic island of a Divided or a Directional driveway.
(o) "Curb Opening/Cut" (R), the length of the opening along the road curb for an approach and its radii.
