Year 2 monitoring completed to support regional BMP monitoring network

The Southern California Stormwater Monitoring Coalition (SMC) has completed the second sampling year of its new Regional BMP Monitoring Network, collecting data from six stormwater BMPs across Southern California during the 2023-2024 wet-weather season.

SMC member agencies wrapped up Year 2 monitoring in April.

Although collecting monitoring data from BMPs requires extensive planning and training, the insights generated from this new regional monitoring program have the potential to address significant, persistent knowledge gaps in managers’ understanding of how to optimize the performance, operation and maintenance of structural stormwater BMPs.

This summer, SCCWRP will be helping SMC member agencies analyze and submit their Year 2 data using a new data portal. Because some BMPs were damaged during the season’s larger-than-average storm events, researchers also are in the process of verifying the viability of the data collected at those sites.
