Maintenance will be completed annually in the Country Club Heights (CCH) registered area to ensure proper functioning condition. El Dorado County plans to inspect all key and essential treatment BMPs within the CCH registration in accordance with the protocols described in the BMP RAM User Manual V2 (2NDNATURE 2015) or acceptable equivalent method as required by the NPDES permit. These inspections are used to assess condition/performance and initiate maintenance. Inspections of all BMPs will take place annually during spring, summer, or fall. The County has developed a robust ArcGIS field maps application that will also help direct this effort.

Benchmark and threshold values for BMP condition have been established. These values are typically evaluated in a dry condition but seasonal and storm event monitoring will take place. El Dorado County plans to measure the infiltration capacity of basins using CHP readings or equivalent methods. All BMPs will be inspected per BMP RAM protocols and maintained annually as needed.
