Baffle Box Effectiveness Monitoring Report

Stormwater Academy, University of Central Florida

This final report summarizes the results of storm event monitoring of four baffle boxes to determine their stormwater pollutant removal effectiveness. Two first generation baffle boxes and two second generation, nutrient removal baffle boxes were monitored. On average, the stormwater pollutant load effectiveness of first generation baffle boxes was only 0.50% for TN and 2.3% for TP, while the load reduction effectiveness of the second generation baffle boxes was 19.05% for TN and 15.50 for TP. Neither first nor second generation baffle boxes were effective in reducing fecal coliform loads.
