At what point do buffers typically begin?

Buffers typically begin at the top of the bank or normal water level because this is the area where land meets the water, and the buffer plays a key role in protecting the water body from runoff and sedimentation. The buffer zone is crucial for filtering pollutants and stabilizing the bank to prevent erosion. By starting at the top of the bank, the buffer can effectively intercept and absorb runoff before it enters the waterway.

This location also allows for the maximum benefit to habitat and biodiversity, providing a transition area where terrestrial and aquatic ecosystems can interact. Plants within the buffer zone help stabilize the soil and serve as a habitat for wildlife, making this the most effective starting point for buffers in terms of environmental protection and ecological balance.
