Aug. 2007 Central Coast Field School
August 14-16, 2007
Arroyo Grande, CA
SRF and Central Coast Salmon Enhancement will offer a course addressing culvert and road drainage practices to protect and benefit steelhead and water quality in the central coast region with Pacific Watershed Associates. This course will include several sessions in the field and will focus on 1) 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 twill highlight appropriate culvert sizing for peak stream flows, sediment and woody debris in transport. The class will include 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 will learn 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.
