 This Excel spreadsheet projects soil loss and sediment discharge from a site using the Universal Soil Loss Equation (USLE), based on the timing of land disturbance, restoration, and the implementation of erosion control BMPs.
-Note that the spreadsheet estimates soil loss from sheet and rill erosion only. It does not predict soil loss resulting from concentrated flow, slopes steeper than 33%, gully erosion or streambank erosion. If those areas exist on a site, they should be addressed through the use of prescriptive erosion control measures.

+  *To meet the standard, a representative “worst case” slope/slope length should be chosen and it's characteristics entered as a new "Bare Ground" activity.
-  *When a slope and/or slope length is changed by grading during the bare soil period, select another bare soil row under "Activity" and enter its corresponding date. Then enter a new slope and/or slope length in the appropriate column(s). This can be used to represent topsoil stripping, followed by mass grading.

   *While the WDNR guidance states that the USLE spreadsheet should not be used on slopes over 20%, County submittals should include slopes up to 33%.
   *In addition to the USLE calculation, erosion control plans should include a map, clearly showing the location of the flow paths modeled in the spreadsheet(s).
