What characterizes a wind-borne debris region?

A wind-borne debris region is characterized by locations that are subject to high winds, which can transport debris that poses a risk to structures and life. Specifically, the correct choice identifies regions located within 1 mile of the coastal mean high water line, where wind speeds are typically high due to their proximity to open water.

The dynamics of wind patterns in coastal areas contribute to the heightened risk of wind-borne debris. Such regions are particularly vulnerable during severe weather events such as hurricanes and tropical storms, where sustained winds can exceed 100 mph, causing loose objects and materials to become hazardous projectiles.

In contrast, areas far inland with low wind speeds do not fit the criteria for wind-borne debris regions, as the wind strength is insufficient to lift and carry debris. Choices that mention wind speeds below 100 mph or tornado-prone regions are also not representative of the dynamic and hazardous nature of the conditions found specifically near the coast where high winds can mobilize debris, ultimately affecting construction and safety standards.
