Caltrans Erosion Control Workshops: Fall 2006

Improving Vegetation Establishment and Erosion Control with Compost-Based Specifications

A series of five workshops, sponsored by the California Integrated Waste Management Board (now known as the Department of Resources Recycling and Recovery) and California Department of Transportation, were held across the state to introduce new compost use specifications to district designers including landscape architects, biologists, and storm water quality coordinators. These workshops provided designers with the opportunity to comment, suggest revisions, and ask compost and water quality-related questions of a diverse team of experts.

These workshops featured practical tools and information on using compost to reduce erosion and improve the establishment of roadside vegetation.


Topics covered included:

  • The characteristics and uses of mulches, soil amendments, and organic fertilizers.
  • The benefits of compost for roadside applications, including reduced runoff, improved infiltration, improved erosion control, and filtration.
  • The U.S. Composting Council's Seal of Testing Assurance Program, the national compost quality and labeling program.
  • Using compost to reduce erosion and improve the establishment of roadside vegetation.
  • Innovative Caltrans projects, pros and cons of different types of applications, and lessons learned.
  • Panel discussion on using compost and mulch on roadside applications.


Stakeholders included:

  • University professionals
  • Researchers
  • Soil scientists
  • California compost industry professionals
  • Landscape architects
  • Caltrans representatives
