Grading Plan

The purpose of the grading plan is to accurately locate elements in the vertical dimension. The existing grade at all doorways is 5007.98' and will not change.

1. prepared on a base sheet including a north arrow and a scale
2. include all (exact location) existing site features that remain in the proposed design
3. include all (exact location) proposed structural features (pavement, walls. curbs, permanent objects, etc.)
4. existing grades (spot elevations) - boxed or placed in parenthesis or otherwise delineated differently than the proposed spot elevations
5. existing grades (contours) - smooth dashed lines
6. proposed grades (spot elevations)
7. proposed grades (contours) - smooth solid lines
8. include all high and low points, and spot elevations at ends and corners of all walls, steps, ramps, etc.
9. all buildings should be given spot elevations at corners as well as finished floor elevation
10. rim elevations at all drain locations
11. communicate with arrows and slope percentages the surface drainage

Following is an incomplete series of examples of General Notes and Legend contents that will appear on the Grading Plan.
