The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number EPIMS-MEN-13441-R1, pursuant to Section 1602 of the Fish and Game Code to Pacific Gas & Electric Craig Geldard.
The project is limited to one encroachment. The encroachment is for culvert removal, stream restoration, and revegetation on an unnamed tributary to Rattlesnake Creek. Implementation of PG&E’s Wildfire Safety Inspection Program in November 2019 resulted in impacts to streambed habitat of the unnamed tributary. The unsanctioned work included installing an 18” diameter culvert and grading a road to access nearby structure. Up the road from the crossing at the structure pad, earthmoving activities occurred to accommodate heavy equipment for repair of a power transmission pole. PG&E has self-reported the unpermitted activity which impacted the stream channel. The project includes decommissioning an access road and removing an undersized and improperly installed culvert. Additional activities to reduce erosion and sediment impacts include
1) decommissioning the access road, installing cross road drains, and applying erosion controls along the access road; and
2) removing debris, restoring contours of the structure pad to promote natural sheet flow and applying erosion controls at the structure pad location.
In-stream work for this encroachment will include excavation and removal of the unpermitted culvert. Stream restoration activities such as bank stabilization, grading, channel clearing and revegetation are proposed to return the channel to natural conditions using an undisturbed upstream reference reach as a guide. If work for this encroachment is interrupted from early rain events, interim erosion control measures will be implemented to prevent sediment delivery to waters of the State.
