Which statement about a grading plan’s cross-sections is true?

• A. They Show Only Plan View Without Elevations
• B. They Provide Construction Schedules
• C. They Establish Elevations And Slopes For Final Grades
• D. They Specify Environmental Permits

Answer: (C)

Cross-sections in a grading plan are vertical slices through the site that show how high the surface sits at different stations and how steeply the finished surface will slope. They display the existing ground and the proposed final grade with the elevations along the section, making the exact final elevations and the required slopes clear. This information is essential for calculating cut and fill quantities and for ensuring proper drainage and stability of the graded surface. That’s why establishing elevations and slopes for final grades is the correct purpose of grading plan cross-sections. Plan views, schedules, and environmental permits come from other parts of the project documents, not from these cross-sections.
