Best Management Practices Statistical Estimator (BMPSE) Version 1.2.0

The Best Management Practices Statistical Estimator (BMPSE) was prepared by the U.S. Geological Survey (USGS) in cooperation with the Federal Highway Administration (FHWA), which are agencies of the U.S. Federal government. The data used for these analyses were derived from the December 2019 version of the International Stormwater BMP Database (http://www.bmpdatabase.org/). The International Stormwater BMP Database was developed by Wright Water Engineers, Inc. and Geosyntec Consultants for the Water Environment Research Foundation, the American Society of Civil Engineers/Environmental and Water Resources Institute, the American Public Works Association, the Federal Highway Administration, and U.S. Environmental Protection Agency. In some cases, however, the data used in this analysis are different from the data found in the December 2019 version of the International Stormwater BMP Database because the author worked closely with Jane Clary, the Project Manager of the BMP database to resolve a number of issues that were identified during the process for extracting, checking, and manipulating the data to do this analysis. The data were extracted from the International BMP Database and imported into the Best Management Practices Statistical Estimator (BMPSE). The USGS and the FHWA reserve the right to revise these statistics pursuant to further analysis and review. These statistics have been used by the USGS and is released on condition that the USGS or the FHWA may not be held liable for any damages resulting from their use.
