Which factor does NOT influence the ground snow load in a given county?

The ground snow load in a given county is primarily affected by factors that relate to its environment and climate, such as geographic location, building height, and local climate.

Geographic location determines the average snowfall and prevailing weather patterns in the region, which directly impacts snow accumulation. Building height is also relevant because taller structures may experience different wind patterns and snow loads due to wind drift or other environmental influences. Local climate further affects snowfall patterns, including temperature variations that influence whether precipitation falls as snow or rain.

The use of construction materials does not directly influence the ground snow load. Instead, it pertains more to the structural design and load-bearing capacity of a building. While different materials can affect how a building responds to snow loads, they do not change the amount of snow that lands on the ground itself. Thus, construction materials do not play a role in determining the ground snow load in a specific area.
