Development of a road cut and fill land use category for the Pollutant Load Reduction Model (PLRM)
Final Report [pdf]
Please contact Kevin Drake at Integrated Environmental Restoration Services, Inc. with questions regarding the use of RCAT.
Using the most complete set of directly measured erosion data in this region, supplemented by additional targeted rainfall simulation under this project, the project team developed the runoff pollutant concentration values needed to support a road cut and fill slope land use category. In collaboration with agency personnel, the team also developed an assessment methodology for directly measuring several key erosion parameters in the field.
After several discussions with the developers of the Pollutant Load Reduction Model (PLRM), it became clear that formal integration of the road cut and fill land use into PLRM would require a new module that was beyond the scope of this project. Therefore, we a simple, stand-alone spreadsheet tool – the RCAT – was developed. Regulators and project implementers can use the tool to estimate the sediment loading potential of cut and fill slopes before and after project implementation. The data outputs from this tool (sediment loads and runoff volumes) can be used in conjunction with PLRM or separately.
