(A) The design features described herein and illustrated in Figure 1, which figure was attached to Ordinance 2008-01 and is hereby adopted by reference as if set out in full, shall be used by the applicant in dimensioning a proposed driveway or driveway system on plans accompanying the driveway permit application. The dimensions to be used for various driveway design features, shown as a standard with a working range of dimensions, are given in Tables 1 to 7, referenced in §§ 94.046 to 94.054, attached to Ordinance 2008-01 and hereby adopted by reference. These standard dimensions shall be used. The Department of Public Works may specify particular dimensions so a particular driveway system will accommodate vehicle movements normally expected without creating undue congestion or hazard on the street or to provide reasonable access.
(B) The letters in the following design features refer to features in Figure 1 which is adopted by reference:
(1) Intersecting angle, A, the clockwise angle from a street centerline to a driveway reference line which is the centerline or the edge of the driveway;
(2) Driveway width, B, the distance between driveway edges of pavement or edges of the gravel surface measured at the point where the edges of the driveway become parallel, point B in Figure 1. 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;
(3) Entering radius, C, the radius of a driveway edge curve on the right side of a vehicle entering the applicant’s property;
(4) Existing radius, D, the radius of a driveway edge curve on the right side of a vehicle leaving the applicant’s property;
(5) Curb ending, E, the length of the height transition of the driveway curb from ground level to full curb height along an uncurbed street. This curb transition may be ten feet minimum;
(6) Right-turn lane length, F, the length of an auxiliary lane constructed preceding the driveway to accommodate right-turn traffic entering the applicant’s property;
(7) Right-turn lane width, G, the width edge-to-edge of a right-turn lane, or the width edge-to-edge at the full width of entering and exiting tapers;
(8) Entering taper, H, the length of a pavement widening, preceding the driveway for a right-turn lane or taper;
(9) Exiting taper, J, the length of a pavement narrowing, following the driveway;
(10) Entrance drive width, K, the width of the portion of a divided or a directional driveway that is used by a vehicle entering the applicant’s property;
(11) Exit drive width, L, the width of the portion of a divided or a directional driveway that is used by a vehicle leaving the applicant’s property;
(12) Island width, M, the edge-to-edge distance between an entrance drive and an exit drive;
(13) Island length, N, the distance between ends of the island, measured parallel to the entrance drive;
(14) Nose offset, P, the distance between the edge of pavement and the traffic island of a divided or directional driveway;
(15) Curb cut, R, the length of the opening along a street curb for a straight-sided residential driveway; and
(16) Distance between driveways, S, the inside distance between two adjacent driveways measured along a street right-of-way line.
