Article VII Definitions

Slope. A degree of deviation of a surface from the horizontal, measured as a numerical ratio, percentage, or in degrees. Expressed as a ratio, the first number is the horizontal distance (run) and the second is the vertical distance (rise), as 2:1. Expressed as a percentage, the vertical distance (rise) is divided by the horizontal distance (run) and is then multiplied by 100. A 2:1 slope is a 50 percent slope. Expressed in degrees, the slope is the angle from the horizontal plane, with a 90-degree slope being vertical and 45 degrees being a 1:1, or 100 percent slope.
