Synthesis of Information Related to Highway Practices. Topic 53-09. Use of Unmanned Aerial Systems for Highway Stormwater Inspections

Monitoring of stormwater best management practices (BMPs) is a requirement of most state departments of transportation (DOTs) construction permits and post-construction EPA National Pollutant Discharge Elimination System permits. This monitoring typically involves expensive and staff-intensive efforts for regular inspection to ensure the BMPs are functioning as designed and are not in imminent need of maintenance (e.g., clean-out). In recent years, the use of Un-manned Aerial Systems (UAS) has evolved rapidly as a tool with the potential to both reduce the costs and improve the data collected during stormwater management inspections for state DOTs. To date, UAS monitoring of stormwater BMPs conducted by state DOTs has demonstrated promising results (or potential applications) with regard to speed, accuracy, and repeatability for several important BMP performance and maintenance factors. The objective of this synthesis is to document the current practices of state DOTs in using UAS as a tool for stormwater BMP inspections.
