Quantifying Nutrient Pollution Reductions Achieved by Erosion Remediation Projects on Vermont’s Roads

Transportation networks have been recognized as contributors to water quality impairment by discharging stormwater, sediment, and nutrients to receiving waters. Prior research in Vermont has documented the role of unpaved roads on water quality impairment (Wemple, 2013; Wemple, 2016). This project aims to expand this work by focusing on gully erosion on Vermont’s roads and quantifying effectiveness of erosion control measures to mitigate gullying at concentrated road discharge points. In this project the research team aims to (1) quantify rates of sediment and phosphorus production associated with erosion at concentrated road drainage points, (2) assess the effectiveness of erosion control measures in reducing sediment and phosphorus from roads, and (3) develop a framework for providing credits for erosion mitigation measures that can be implemented under the Lake Champlain Total Maximum Daily Load (TMDL) for phosphorus.
