2007 Central Coast Road Decommissioning & Enhancement Field School

Tuesday, October 23, 2007 to Thursday, October 25, 2007

This field school addressed culvert and road drainage practices to protect and benefit steelhead and water quality in the Central Coast region.

The course included several sessions in the field and focused on proper ditch relief and stream crossing culvert installation as well as installation of critical rolling dips or measures to eliminate stream diversions. Classroom and field methods highlighted appropriate culvert sizing for peak stream flows, sediment and woody debris in transport. The classes included approaches for addressing potential road fill and landing failures, as well as spoil disposal techniques and illustrate a variety of road bed and ditch drainage approaches. Participants learned how to properly excavate a stream crossing fill to minimize post excavation erosion and sediment delivery to streams, and how to reduce roadbed width on excessively wide segments of road.
