Understanding Trends in Stormwater Inspection Reports Leading to Recurring Corrective and Urgent Maintenance Issues: Case Study for the Virginia Department of Transportation

Abstract

AbstractStormwater best management practices (BMPs) are essential for meeting water quality and flood control goals, but their long-term effectiveness depends on sustained maintenance. In this study we analyzed a large BMP inspection dataset of 17,843 ...Five-year analysis of 2,535 stormwater BMPs (2020-2024) reveals 15% of the BMPs account for 69% of corrective and 72% of urgent issues (costlier than routine maintenance). Spatial analysis of these Corrective and Urgent (CU) BMPs demonstrates patterns ...Practical ApplicationsThis study showed that most stormwater maintenance issues can come from a small number of best management practice (BMP) facilities. By tracking which BMPs have repeated issues, agencies can focus time and money where it matters ...
