Document Description
This Agreement relies on the Notification materials and a CDFW site inspection by
Environmental Scientist Andrew Orahoske on November 13, 2019. The project is limited to 3 encroachments
(Table 1). One encroachment is to upgrade a stream crossing as recommended by staff from the North Coast Regional Water Quality Control Board. Work for this encroachment will include excavation, installation of a new properly sized crossing, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion.
Two encroachments are for stream restoration at a failed onstream reservoir and a roadside streambank.
The Notification and site inspection revealed the use of two water wells located at (lat./long.): Well-1: 40.9701, -123.7362; Well-2: 40.9699, -123.7328. CDFW did not fully evaluate hydraulic connection of the wells 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 wells 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 process (PLN-12848-SP).
No surface water diversion is authorized by this Agreement. The site of the failed onstream reservoir matches several prior filings with the Division of Water Rights for surface water diversion: S027156, S025091, S025126, S027157, S025079, S025128. No water diversion infrastructure was observed at this location during the CDFW site inspection on November 13, 2019.
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.
