Subsoil storm drains shall not be less than ____ inches in diameter.

The correct answer is: 6

Subsoil storm drains are critical in managing excess water and preventing soil erosion around structures and landscapes. The specification that these drains should not be less than 6 inches in diameter is based on the need to handle adequate water flow and to reduce the risk of clogging. A larger diameter allows for better drainage capacity, ensuring that water is effectively channeled away from the area, thereby protecting the integrity of soil and foundation structures. In this context, a diameter smaller than 6 inches could lead to insufficient drainage, increasing the likelihood of flooding or water accumulation, especially during heavy rain events. This specification is grounded in both practical engineering principles and building codes that aim to maintain safety and functionality in construction practices. Thus, the correct minimum diameter of 6 inches ensures effective performance of the drainage system, minimizing potential issues associated with water management in construction and landscaping.
