Effort launched to assess BMP maintenance condition across L.A. region

SCCWRP has launched a summer-long effort to visually assess the condition of biofiltration stormwater BMPs (best management practices) across the Los Angeles region using a standardized, rapid method – an inspection effort that will enable researchers to build a baseline regional understanding of the state of operations and maintenance (O&M) for these systems.

The study, which kicked off in July, is aiming to inspect 40 to 50 publicly accessible biofiltration BMPs for visible maintenance issues, such as erosion, clogging, and overgrown vegetation. A web-based form is being used to capture monitoring data on a mobile device.

Researchers plan to use the insights to better understand how O&M practices affect biofiltration performance, as well as help managers develop more effective O&M plans.

In Southern California, stormwater managers have spent billions of dollars implementing and managing stormwater BMPs to remove pollution from runoff. However, the O&M needs for these systems can vary from site to site, making it challenging for managers to allocate O&M resources and train staff.
