El Dorado County plans to inspect all key and essential treatment BMPs within Montgomery Estates 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.
Benchmark and threshold values for BMP condition will be set during the first year of registration. These values are typically measured after snow has melted. El Dorado County completed the first round of inspections in fall 2016. In BMP RAM, the infiltration observation for dry basins and infiltration offers a “User Defined” method. The California Stormwater Quality Association (CASQA) BMP Fact Sheet on infiltration basins suggests inspecting the basins 48 to 72 hours after a storm event to determine that all water has infiltrated. If all water has not infiltrated during this time period, maintenance should be performed. El Dorado County plans to incorporate the infiltration capacity of basins using both the CASQA method along with supplemental CHP readings as needed. All BMPs will be inspected per BMP RAM protocols.
