Roadways can carry pollutants from stormwater runoff into nearby waterbodies; therefore, transportation authorities must effectively manage runoff along these roadways. This can be challenging because roadways may cross several watersheds, and motorized vehicles are transient, making enforcement for pollution controls difficult to implement. Best management practices (BMPs) can help transportation professionals manage the quantity and improve the quality of stormwater runoff. The International Stormwater BMP Database is a publicly accessible, online, centralized resource of scientifically sound information on stormwater management BMPs, data, case studies, and other support products. This project provides guidance for transportation professionals on how they can use the International Stormwater BMP Database to advance their roadway stormwater management efforts. Additional information on this project can also be found on the The National Academies of Sciences, Engineering, and Medicine's website.
