Landscape construction materials include grading.

• A. Irrigation
• B. Grading
• C. Planting
• D. Lighting

Answer: (B)

Grading is the shaping and leveling of the ground to create the designated elevations and slopes. In landscape construction, preparing the site this way is essential because it controls drainage, prevents water from pooling, and provides a solid, even base for placing other materials and features. Without proper grading, installing hardscapes, planting areas, or drainage systems won’t perform correctly, since the ground itself dictates how water and loads will behave. Think of grading as the earthwork that sets the stage: moving soil to cut or fill to the required elevations, ensuring slopes direct water away from structures, and creating the contour needed for patios, paths, and beds. The other items—irrigation, planting, and lighting—are important components to install, but they rely on the ground being properly prepared first.
