In storm drain inlet protection practices, what is the allowable drainage area range depending on the type?

The correct answer reflects the standards set for storm drain inlet protection practices, which are designed to prevent sediment and debris from entering storm drain systems during construction activities. The specified drainage area range of one-quarter to one and one-half acres indicates the acceptable size of the area that can contribute runoff to a storm drain inlet where protective measures are implemented.

This range ensures that the protective practices are effective in managing sediment control for typical construction site sizes. Storm drain inlet protection methods, such as silt fences or sediment traps, are evaluated based on their ability to manage runoff from these specified areas, achieving a balance between practicality and environmental protection.

The other options suggest different sizes that exceed or do not meet the typical range established by regulations. Recognizing the correct range is fundamental for maintaining compliance with local regulations and ensuring effective sediment control on construction sites.
