The Runoff Reduction Report

This report includes recommendations for green stormwater infrastructure practices at 4 sites in the town of Burlington. Each site is displayed with a design of the recommended practice, detailed description of our recommendations, and an informational table. Each table shows an estimated drainage area, our recommended green infrastructure, annual gallons of runoff treated, nitrogen and phosphorus pollution reduction amounts, and the suggested size of each practice. These estimations were calculated based on the drainage area, annual rainfall estimates specific to Connecticut, and literature export values.


GSI Summary Table

The following calculations display the potential pollutant-reducing benefits if the practices identified within the report were implemented:
