Urban Stormwater BMP Performance Monitoring
This manual provides targeted practical assistance in conducting water quality monitoring and reporting data that are useful for assessing effectiveness of stormwater best management practices (BMPs). It was developed by integrating experience gleaned from field monitoring activities conducted by members of the American Society of Civil Engineers (ASCE) Urban Water Resources Research Council and through the development of the International Stormwater BMP Database . The overall purpose of the database is to provide scientifically sound information to improve the design, selection and performance of BMPs. The monitoring guidance manual, originally released in 2002, was extensively updated in 2009. The purposes of the updated manual are two-fold:
1) Improve the state of the practice by providing and enhancing a recommended set of protocols and standards for collecting, storing, analyzing, and reporting stormwater BMP monitoring data that will lead to better understanding of the function, efficiency, and design of urban stormwater BMPs.
2) Provide monitoring guidance for “Low Impact Development” (LID) strategies at the overall site level (e.g., monitoring overall sites with multiple distributed stormwater controls).
