1.9 Slope and Soil Type Adjustments

1.9

Land slope and soil type have significant impact on the ability of a buffer to remove pollutants from surface runoff.

Steeper slopes reduce performance by allowing greater pollutant transport and less time for infiltration. Steeper slopes will require wider buffers. tc "Steeper slopes reduce performance by allowing greater pollutant transport and less time for infiltration. Steeper slopes will require wider buffers.

Soils with higher infiltration capacity can reduce runoff to a greater degree than soils having lower infiltration. Soils with lower infiltration capacity will require wider buffers. Finer-textured soils typically have lower infiltration than sandy soils.
