1.6 Buffer Site Design

Important design elements for any buffer include its size, the kind of vegetation it contains, and how it is managed. Each of these elements is dictated by site factors including pollutant type and load, the buffer�s capacity to trap and transform these pollutants and the desired level of pollution reduction. Use the figure above as a road map to guidelines on site design.
