What is a likely consequence of poor site drainage in building design?

Poor site drainage can lead to significant problems for a building, the most pressing of which is the potential for flooding and damage to the foundation. When water is not properly directed away from the structure, it can accumulate around the foundation, leading to various issues such as soil erosion, hydrostatic pressure, and water infiltration into basements or crawl spaces. Over time, this can weaken the foundation, resulting in cracks, shifting, or even structural failure.

A well-designed drainage system is essential for maintaining the integrity of a building. It prevents water pooling around the foundation and mitigates the risk of flooding, which can lead to costly repairs and maintenance. Therefore, the consequence of poor drainage directly correlates with the risks of flooding and compromising the foundation's stability.
