Please take note that the current Caltrans compost specifications align very closely with the US EPA specifications below.
Vegetative Biofilters Three different types of vegetated biofilter BMP types have been identified and are described in this manual. These include:
- Grass swales
- Vegetated filter strips
- Bioretention cells
Please note that this report does recommend adding 10-20% composted organic matter, but it is unclear if the pollutant removal test results included these amendments.
Compost/Soil Amendment Specification Notice how these specifications closely align with Caltrans compost specifications
