The correct choice highlights that a buffer zone is typically measured from the edge of the water to the edge of the disturbed area. Buffer zones play a crucial role in environmental protection by serving as transitional areas that reduce the impact of human activities on aquatic ecosystems. The space helps filter pollutants, reduce erosion, and provide habitat for various species, thereby preserving water quality and ecological balance.

When measuring a buffer zone, it is essential to assess the proximity of disturbances—such as construction activities or land development—to water bodies. By defining the buffer from the edge of the water, regulations and practices can be established to protect sensitive areas from adverse effects that arise from nearby construction or land alteration.

The other options, while they reference various measurements relating to properties or constructions, do not specifically address the ecological context of how buffer zones are intended to function in relation to water bodies. Thus, they do not accurately represent the standard definition and application of a buffer zone.
