Document Description
This Agreement relies on the Notification materials and a desk review without a CDFW site inspection. The project is limited to five encroachments (Table 1) to upgrade stream crossings. Work for 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.
Crossing-1 40.9437, -123.6501 Replace existing culvert with minimum 36-inch diameter culvert.
Crossing-2 40.9445, -123.6506 Install vented ford with minimum 24-inch diameter culvert. Rock road
approaches minimum of 50 feet at both approaches
Crossing-3 40.9449, -123.6505 Replace existing culvert with minimum 24-inch diameter culvert.
Crossing-4 40.9447, -123.6498 Replace existing culvert with minimum 24-inch diameter culvert.
Crossing-5 40.9442, -123.6492 Replace existing culvert with minimum 36-inch diameter culvert.
The Notification also discloses the use of a well located at Lat/Long 40.9440, -123.6515. This well is presented as the sole source of water for all 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, the well may be hydraulically connected to streams and/or springs and shall be evaluated for potential impacts from commercial cannabis irrigation use through the County’s conditional use permit (PLN-13037-CUP).
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.
