Erosion Control Presentations

Caltrans

The powerpoint presentation below communicates the key role played by compost in restoring post-construction plant/soil/water inter-relationships, reducing runoff and reducing off-site transport of pollutants such as heavy metals, hydrocarbons and nutrients. The research data summarized in this presentation can be obtained from the reports listed further down this page.

Compost and Water Quality PPT

WSDOT

WSDOT Compost Amended Vegetated Filter Strips - presented by Sandy Salisbury. This use of compost in very narrow areas adjacent to the highway to increase water infiltration should be very, very similar to how Caltrans would use these materials. Included data on runoff, infiltration and pollutant load and concentration.
