The Caltrans Landscape Architecture Program, in partnership with CalRecycle, University of California Riverside, University of Washington, Filtrexx Sustainable Technologies, Salix Applied Earthcare, United States Composting Council, California Compost Coalition, and R. Alexander Associates, Inc., is presenting two free half-day workshops that focus on the use of compost-based best management practices (BMPs) to improve roadside revegetation, control erosion, filter stormwater, reduce runoff, and improve stormwater quality.

In addition to rolling out innovative methods of improving water quality, these workshops will provide attendees with the opportunity to ask questions of a diverse team of experts. The workshop team consists of University professionals, researchers, soil scientists, California compost industry professionals, Caltrans landscape architects, and other subject matter experts.

The workshop is for Caltrans district designers, including landscape architects, biologists, and stormwater quality coordinators; Caltrans contractors, and others involved in improving stormwater quality. The workshop will provide practical tools and information on improving roadside revegetation and stormwater quality with compost based BMPs.
