That is not shown in plan; however, when grading the TS and BS will reflect the tread slopes. Grading Ramps • Ramps are inclined sidewalks at a uniform slope. typically ranging between 5 -8% • Ramps can be graded perpendicular to the length or cross pitched • Spot elevations are normally given at top and bottom. • A directional arrow is usually drawn indicating the downhill slope. Grading for walls • Contours are not shown in walls. • Contours run to the edge of a wall and emerge on the other side or at the end. • Spot elevations are given at top of wall (T.W.) and at bottom of wall (B.W.) • Runoff and drainage are critical to a wall’s durability.
