There are four different types of soils by levels of permeability and runoff potential in the Buffalo Creek watershed. These are rated from A to D, with A-type soils having the highest level of permeability and lowest runoff potential and D having the lowest level of permeability and highest runoff potential. C-type soils are the most common, and occur in the eastern and central parts of the watershed. B-type soils primarily occur in the western part of the watershed. D-type soils are scattered throughout the watershed and A-type soils occur in areas of the southern and southeastern parts of the watershed.
