Rainfall-Runoff Erosivity Factor R is an indication of the amount of rainfall and peak intensity sustained over period Soil Erodibility Factor Sandy soils= low K values (<0.2) Silt loams = medium values (<0.4) Clay soils – high values (>0.4)
Slope Length Factor Computes the effect of slope length and steepness on erosion � Budget concerns � Enforcement concerns � Third-party / NIMBY considerations � CEQA considerations � Importance of thorough back-up information � Potential effects on LEED rating considerations
