Erosion Control

Compost modifies the physical soil properties, improving water-holding ability and resistance to compaction. For this reason, compost is more commonly being used as an erosion control material that enhances soil. Compost is made from readily available, inexpensive materials and is gaining ground as an accepted material for erosion control measures in construction projects and roadside landscaping in California whereby road and construction projects degrade and compact soil, causing breakdown of aggregates and loss of structure.

Together, the County Watershed Protection Program and the Recycling Section are working together on an erosion control pilot study at Poway Landfill. The control study is designed to measure the effectiveness of compost socks versus straw waddles in erosion control and slope stabilization over a one year period.
