Document Description
The County is required to perform regular routine maintenance of drainage facilities and water crossings at approximately 175 locations throughout Plumas County (Figure 1), generally within or adjacent to County roads. All of the maintenance locations are in watercourses or riparian habitats (stream/riparian zones) which may fall under the jurisdiction of the California Department of Fish and Wildlife (CDFW). As such, CDFW may require a Lake and Streambed Alteration Agreement (LSAA) to authorize the maintenance activities. The County wishes to simplify and expedite the LSAA approval process by obtaining from CDFW a long-term (e.g., 12 year) Routine Maintenance LSAA that would allow for maintenance activities at various locations. Routine maintenance activities, or treatment types, include 1) Debris or obstruction removal, 2) Beaver dam removal, 3) Silt, sand or sediment removal. 4) Vegetation control in channels, 5) Minor erosion control work, 6) Channel alignment and levee maintenance, 7) Repair of facilities, 8) Geotechnical sampling, 9) Temporary water diversions, and 10) Bridge washing, graffiti removal and painting. Detailed mitigation measures are specified for each maintenance location based on biological and cultural investigations and the anticipated maintenance treatment.
