SGLA LARE Grading, Drainage and Stormwater Management Practice Exam

Grading plays a crucial role in construction projects as it focuses on modifying the ground surface to create desired contours and slopes. This adjustment is essential for several reasons, including ensuring proper drainage and stormwater management, enhancing the stability of structures, and preparing the site for landscaping or other developments. By creating a level surface or specific gradients, grading helps manage how water flows across the site, guiding it away from foundations and preventing erosion or pooling.

While water flow is affected by grading, it is the actual ground surface that is directly modified through excavation and embankment processes. Adjusting the existing terrain allows for better design and functionality of the project as a whole. Other factors like building materials or plant selection may be influenced by the grading process, but they are not modified directly by it. The primary purpose of grading is to alter the ground surface configuration to accommodate the intended construction and overall site management.
