Document Description
The project is limited to five encroachment(s) (Table 1). Two encroachments are for water diversion from unnamed tributaries to Canon Creek. Water is diverted for domestic use only. Work for the water diversion will include installation, use and maintenance of the water diversion infrastructure. The three other proposed encroachments are to upgrade failing and undersized stream crossings. Work for this/these encroachments will include excavation, removal of the failing crossings, replacement with new properly sized crossings, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. POD-1 40.8451, -123.9032 Install a spring box for domestic use Domestic Use - Water diversion for domestic use year-round. Permittee shall implement Seasonal Diversion Minimization: max 300 gallons per day for POD-1 & POD-2 combined from May 15 – October 31, 80% bypass at all times. POD-2 40.8501, -123.9076 Install a spring box for domestic use Domestic Use - Water diversion for domestic use year-round. Permittee shall implement Seasonal Diversion Minimization: max 300 gallons per day for POD-1 & POD-2 combined from May 15 – October 31, 80% bypass at all times. Crossing-1 40.8488, -123.9075 Install armored fill crossing or appropriately sized culvert to handle 100- year storm event. Crossing-2&3 40.8477, -123.9071 40.8473, -123.9072 Two abandoned crossings in close proximity to be treated as a single project. Decommission crossings and restore stream channel Crossing-4 40.8453, -123.9053 Install minimum 24-inch diameter culvert downstream of the existing unarmored ford crossing. Relocating the crossing out of the wetland and onto stable banks will minimize erosion and stream impacts. The Notification also discloses the use of a well located at Lat/Long 40.8448, -123.9058. This well is presented as the sole source of water for all commercial cannabis cultivation needs on the property. CDFW did not evaluate hydraulic connection of the well to surface water, nor was a hydrogeologic evaluation prepared by a licensed geologist provided for CDFW review. Based on the available resources, and the site inspection, the well may be hydraulically connected to streams and/or springs and shall be evaluated for potential impacts from commercial cannabis irrigation use through Humboldt County’s cannabis cultivation permit (PLN-12799-ZCC). No other projects that may be subject to FGC section 1602 were disclosed. This Agreement does not retroactively permit any constructed reservoirs (including “ponds”), stream crossings, water diversions, modifications to riparian buffers, or other encroachments not described in Table 1.
