Fence, wall, hedge, and rockery height must be measured from the finished grade to the top of the fence as shown in Figure 19.66.050. Where fence, walls or hedges feature varying heights of finished grade on opposite sides of the fence, wall or hedge, then the height must be measured from the side with the lower grade. Fence posts may exceed the height of the top rail by up to 12 inches. For sloped sites, the average height between posts may be used, provided no portion of the fence exceeds the height limit by one foot.
