International Stormwater BMP Database
The International Stormwater Best Management Practices Database (BMPDB) is a repository of BMP field studies and related web tools, performance summaries, and monitoring guidance. Initiated over 25 years ago, the original focus was urban stormwater BMPs (stormwater control measures). Through the support of long-term partners, the project has expanded to develop additional resources related to both urban and agricultural runoff, treatment and management. Separate databases are accessible on this site for urban stormwater BMP performance, agricultural BMPs, stream restoration BMPs, and urban runoff quality characterization (National Stormwater Quality Runoff Database). Special resources have also been developed for Department of Transportation users through the DOT Portal. All of these resources can be accessed through this website, with the most developed tools available for urban stormwater BMPs.
New! In 2025, significant updates to the BMP Database are underway through the support of a new sponsor coalition led by the ASCE Environmental and Water Resources Institute and including the Water Research Foundation, the Mile High Flood District and Villanova University. We are actively seeking BMP performance data submissions and will be completing updates to the statistical analysis tools. To be placed on a contact list for project updates, become a project co-sponsor or learn more about submitting data, contact us.
