What is the purpose of buffer zones during construction activities?

Buffer zones play a crucial role in protecting surface waters from pollution and sedimentation that can result from construction activity. These zones are established as vegetated or natural areas between construction sites and adjacent water bodies, such as streams, rivers, and wetlands. The primary purpose of a buffer zone is to absorb, filter, and reduce the speed of runoff, thereby minimizing the amount of sediment and pollutants that reach these sensitive water resources.

By maintaining a vegetative cover within the buffer zone, soil erosion is significantly decreased, and the natural filtration processes help clean the water before it enters the aquatic ecosystem. This protection is vital not only for preserving water quality but also for safeguarding aquatic habitats and biodiversity, ensuring that construction activities have minimal adverse impacts on the environment.

In contrast, while the other options mention various activities related to construction or land use, they do not address the specific environmental protective function of buffer zones. For instance, providing additional land for construction or creating recreational areas does not fulfill the primary role of mitigating pollution and erosion, nor do they align with the objectives of erosion prevention and sediment control practices. Additionally, while sediment control measures are critical, buffer zones complement these strategies rather than eliminate the need for them, as they primarily serve to prevent issues from occurring at the
