The purpose of this workbook is to provide a simplified approach for evaluating bioretention media mixes used in stormwater control measures. This workbook contains two primary worksheets for bioretention media mix analysis:

1.   A bioretention media mix quality estimation tool (for suppliers) to develop theoretical mixes based on combined material quantities of topsoil and sand.
2.  A bioretention media mix sample quality assurance check for comparison of soil lab results to the USDCM recommended ranges for bioretention mix soil properties (for suppliers, design engineers, or inspectors).
