5C Headquarters. Trinity County is the headquarters for the 5C Program. Mark Lancaster, 5C Program Director and Senior Planner for the Natural Resources Division of the Trinity County Planning Department, was a key figure in getting the program off the ground in 1997.
5C staff not only head the barrier and sediment reduction projects being implemented in Trinity County, but also help to facilitate projects within the other 4 counties; managing program grants, providing staff training, and other resources for the 5C counties and handling overall program projects.
West Weaver Creek Migration Barrier Removal Project The Trinity County Migration Barrier Removal Project at West Weaver Creek and Oregon Street replaced an undersized, perched culvert with a concrete, Con-Tech bottomless culvert. The arch provides for full natural stream bed simulation and the flood capacity at the crossing was designed for the 100-year storm, preventing future culvert blockages, flooding, and blow-outs. This project was ranked as the highest priority project in Trinity County and the 8th highest priority project in the 5C area under the 5C Migration Barrier Inventory. The project restored access to approximately 3.75 miles of anadromous habitat for coho salmon and steelhead trout. Project funding was obtained through the CA Department of Fish and Game' Coastal Fisheries Recovery Grant Program, State Water Resources Control Board Proposition 204, and Trinity County in-kind matching funds. Unfortunately, the outlet pool at the old culvert had become quite a popular swimming hole!
