What is done before grading?

• A. Check Natural Drainage
• B. Install Control Module
• C. Install Irrigation Lines
• D. Compact The Soil

Answer: (A)

Understanding how water moves on a site is tested before any grading happens. By checking natural drainage, you map out where water naturally collects, which way it flows, and how grading will alter those paths. This helps you design slopes and swales to keep water away from foundations and prevent erosion after grading. Therefore, assessing natural drainage is the step done before grading. The other tasks— installing a control module, installing irrigation lines, or compacting the soil—are things that come later in the irrigation or site-prep process, not the initial pre-grading assessment.
