🌱 BSM Specifications (85% Sand / 10% Fines / 5% Organic, Hydraulic Conductivity 2-6 in/hr)

Bioretention Soil Media (BSM) Calculator

Design engineered Bioretention Soil Media (BSM) blend ratios under regional stormwater specifications: blend coarse sand (80% to 88%), clay/silt fines (8% to 12%), and composted organic matter (3% to 5%), calculate coefficient of permeability (k 2 to 6 inches/hour), and bulk aggregate blending profits.
