Oct. 2007 Central Coast Road Decommissioning & Enhancement Field School
October 23-25, 2007
Santa Barbara, CA
Sponsors:
Central Coast Salmon Enhancement, SRF, Pacific Watershed Associates and CA Department of Fish and Game
Instructors:
Danny Hagans and Bill Weaver, Pacific Watershed Associates
The field school will address culvert and road drainage practices to protect and benefit steelhead and water quality in the Central Coast region. This course will include several sessions in the field and will focus 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 will highlight appropriate culvert sizing for peak stream flows, sediment and woody debris in transport. The classes 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.
