What is a "buffer zone" in stormwater management?

A "buffer zone" in stormwater management is specifically defined as an area of vegetation designed to intercept pollutants before they reach water bodies. This type of zonation plays a critical role in the overall strategy for managing stormwater by utilizing natural processes to filter out sediments, nutrients, and other pollutants from surface runoff.

The vegetation in the buffer zone helps absorb water and pollutants, reducing the volume of runoff that enters adjacent water bodies and improving water quality. By acting as a natural barrier, buffer zones can also help stabilize soil and prevent erosion, which can further contribute to cleaner waterways. Overall, the establishment of buffer zones is a best practice in environmentally responsible stormwater management and is recognized as an effective means of protecting aquatic ecosystems.
