BMP performance data collected from 5 sites to support regional monitoring network

The Southern California Stormwater Monitoring Coalition (SMC) has successfully collected monitoring data on the performance of structural stormwater BMPs (best management practices) at five sites – a key milestone in ongoing efforts to build the SMC’s new Regional BMP Monitoring Network.

During the 2022-2023 wet-weather season, the SMC deployed field teams to the five sites during as many as eight storm events per site. The five monitoring sites represent the halfway point in the planned initial buildout of the monitoring network, which is being led by SCCWRP.

The SMC’s Regional BMP Monitoring Network will help address significant, persistent knowledge gaps in managers’ understanding of how to optimize the operation, maintenance and performance of structural stormwater BMPs.

SCCWRP, which recently developed web-based tools for integrating data management and analysis into the network, will beta-test the tools with SMC partners in the coming months. The tools are designed to streamline data processing, confirm quality assurance and ensure consistency in data analysis.
