PApplications:< Prevent Erosion

– Reduce Disturbance / Exposure– Grading (Divert clean water when possible)– Surface Treatments (Mulch, Seed & Mulch, RECP (Blankets) – Reduce Velocity in ditches (Linings, Check Dams)

< Collect Sediment– Silt Fences, Check Dams

< Provide Retention/Detention– Sediment Basins, Traps
