State departments of transportation (state DOTs) are faced with increasing stormwater treatment demands, with tightening treatment criteria and additional pollutant targets. To meet these requirements, DOTs need ready access to reliable information about stormwater treatment Best Management Practices (BMPs) in order to choose effective solutions appropriate for project specific conditions. The International Stormwater Best Management Practices Database (BMPDB) is a repository of BMP field studies, performance summaries, and monitoring guidance. The State DOT Portal is a web tool that provides streamlined access to BMPDB study data and performance statistics that are relevant to state DOTs and other transportation agencies.
The related project NCHRP 25-25/Task 120 developed information on how to access and use the Portal along with an analysis of data of interest to state DOTs. Access the final report and presentation slides summarizing the project HERE.
