How are site grading and drainage systems assessed?

The assessment of site grading and drainage systems is primarily focused on evaluating the physical characteristics and conditions of the land. This involves analyzing the slopes to ensure they are appropriate for directing water runoff, assessing drainage patterns to determine how water flows across the site, and identifying any potential erosion issues that could arise from poor grading or inadequate drainage. Proper grading and drainage are critical for maintaining site stability, preventing water accumulation, and avoiding damage to structures or landscapes due to flooding or erosion.

Other aspects, such as vegetation type or nearby trees, may provide some context about the land's ecological characteristics, but they do not directly assess the effectiveness of grading and drainage systems. Similarly, estimating construction costs is related to financial planning rather than the physical evaluation of grading and drainage. Hence, the focus on slopes, drainage patterns, and erosion potential captures the essential elements needed to ensure that a site is graded and drained effectively, making this approach the most relevant for assessing these systems.
