§ 900-60. Street Design Standards.
900-60.1 Street Grades and Design Speeds.
A.
Minimum grade for all Local and Minor Collector Streets shall be 1.5 percent. Minimum grades for all major collector and arterial streets shall conform to Georgia Department of Transportation standards and regulations.
B.
Minimum grade of less than 1.5 percent on a local street may be approved by the Department, based on adequate engineering designs, where at least 1.5 percent cannot reasonably be achieved due to topographical limitations imposed by the land. In such cases, a Record Drawing and such computations as necessary shall be provided after construction to establish that the street will drain in accordance with this UDO. Street sections where unacceptable pooling, excessive spread at catch basins, or other hazardous conditions occur shall be reconstructed or otherwise improved to eliminate such conditions.
C.
Minimum vehicle design speeds and maximum grades allowable in Gwinnett County by street classification shall be as shown in Table 900.6.
D.
Maximum grade on any cul-de-sac turnaround shall be 6 percent.
Table 900.6. Minimum Design Speeds and Maximum Grades.
Street Category Maximum Grade Design Speed Principal Arterial 8% 60 MPH Major Arterial 9% 50 MPH Minor Arterial 10% 40 MPH Major Collector 10% 40 MPH Minor Collector 10% 30 MPH Local 15% * 25MPH * Grades between 11 percent and 15 percent shall not exceed a length of 150 feet and shall require an "as graded" survey prior to the installation of the curb or utilities. The distance shall be measured as the tangent length between points of curvature.
900-60.2 Vertical Street Alignment.
A.
All changes in street profile grades having algebraic difference greater than one percent shall be connected by a parabolic curve having a minimum length (L) equal to the product of the algebraic difference between the grades in percent (A) and the design constant (K) assigned to the street according to its category (i.e., L=KA).
B.
Constant (K) values are shown in the Table 900.7 for both desirable and minimum acceptable ("hardship") conditions. In all cases, the "desirable" value shall be used, unless it cannot be achieved due to topographic conditions beyond the developer's control. In such hardship situations, the Department may approve a lesser value to the extent required by the hardship situation, but in no event less than the value shown in Table 900.7 as "minimum."
Table 900.7. Constant (K) Values for Vertical Curves.
Crest Curves Sag Curves Street Category Minimum Desirable Minimum Desirable Principal Arterial 151 320 136 155 Major Arterial 84 170 96 110 Minor Arterial 44 80 64 70 Major Collector 44 80 64 70 Minor Collector 19 30 37 37 Local 12 20 26 26 900-60.3 Horizontal Street Alignment.
A.
All new streets shall adhere to the standards governing horizontal curvature and superelevation as set forth in Table 900.8 below:
Table 900.8. Horizontal Curves.
Street Category Minimum Radio (Ft.) Maximum Superelevation Principal Arterial 1,333 0.06 Major Arterial 833 0.06 Minor Arterial 560 0.04 Major Collector 560 0.04 Minor Collector 300 0.04 * Local 181 0.00 * No superelevation will be allowed on Minor Collectors internal to residential subdivisions
B.
Superelevation for horizontal curves shall be calculated utilizing the following formula:
R = minimum radius curve
v = vehicle design speed (MPH)
e = rate of superelevation (decimal of a foot rise per foot roadway)
f = side friction factor
R = v2 / 15 (e + f)
Vehicle Design Speed (v) 30 40 50 60
Side Friction Factor (f) .16 .15 .14 .12
C.
Widening section along existing streets shall be designed reflecting existing curvature and superelevation, if any, unless the existing street has been included in a specific design by the Gwinnett County Department of Transportation or Georgia Department of Transportation which calls for different standards, in which case the project will be coordinated with the overall design.
D.
Superelevation runoff. Roadway edge curves shall be provided for tangent runout (bringing edge from a normal crown to centerline elevation) and superelevation runoff (from the end of tangent runout to the point of design superelevation) in accordance with design standards of the Georgia Department of Transportation or other professional engineering standards.
E.
Tangents and compound curves. Between reverse horizontal curves there shall be not less than the minimum centerline tangents shown in Table 900.9 unless otherwise specified by the Georgia Department of Transportation. Compound radii curves are prohibited. At least the "desirable" length shall be provided unless hardship conditions of topography or property configuration will not allow lengths greater than those shown as "minimum." For compound circular curves, the ratio of the flatter radius to the sharper radius shall not exceed 1.5 to 1.
Table 900.9. Tangents.
Street Category Minimum Tangent Length Desirable Tangent Length Principal Arterial 150 180 Feet Major Arterial 125 150 Feet Minor Arterial 100 120 Feet Major Collector 100 120 Feet Minor Collector 75 90 Feet Local 50 60 Feet Note: Minimum tangents are based on the distance traveled in 1.7 seconds at the design speed for each category of street. Desirable length is based on distance traveled in 2.0 seconds
