Research for the AASHTO Committee on Environment and Sustainability. Task 120. Use of the State Department of Transportation Portal to the International Stormwater BMP Database

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 Practice Database (BMPDB) contains information about numerous BMPs. However, the structure of the BMPDB does not make it simple to retrieve highway specific BMP information, and lacks some data elements of particular interest to DOTs. NCHRP Project 25-25(92) Transferability of Post-Construction Stormwater Quality BMP Effectiveness Studies concluded that while BMP effectiveness data is generally transferable, BMP performance monitoring studies tend to be concentrated in certain parts of the nation due to varying regulatory requirements, access to funding and other factors. The addition of more DOT-specific data from a broader geographic spectrum would make studies of effectiveness and contributing factors better and more robust. Likewise, the consolidation of DOT BMP data and analysis would give stormwater designers easy access to the information needed for good decision-making. Therefore measures to encourage data submittal and to facilitate the storage and transfer of the data are needed. NCHRP 25-25/Task 119, “Enhancing the International Stormwater BMP Database to Serve as a Highway Specific BMP Database” is addressing this need by developing a state DOT-focused Portal to access and analyze relevant data in the BMPDB. NCHRP 25-25/Task 120 will use the enhanced Portal for an original analysis of BMP effectiveness for water quality analyses of interest to state DOTs. Task 120 will also include initial outreach to increase awareness of the BMPDB and the Portal. A main objective of the outreach is to increase the flow of studies to the BMPDB, keeping it current and continually increasing the value of the data and analyses for DOTs. Longer term, the Portal can serve as the primary data clearinghouse for DOT BMP studies.
