- Document Description
- The project is limited to two encroachments (Table 1). One encroachment is to perform maintenance on the inlet and outlet of an existing stream crossing (STX-1). Stream banks at inlet to be modified to prevent stream flow from exiting stream into an adjacent ditch. Armoring also to be added to the inlet. Ditch at inlet with potential to deliver fine sediment will be treated to reduce sediment input. Electric cable spanning stream channel at outlet to be lifted out of the channel. The other proposed encroachment is to upgrade a failing and undersized stream crossing (STX-2). During the 5/12/20, site visit, CDFW observed conditions at the culvert outlet that were not in compliance with Fish and Game Code 5650. Dirt from the road had delivered on top of the culvert outlet and into the stream channel. This has since been cleaned up and erosion control methods have been employed. Permittee shall ensure appropriate erosion control measures are in place for 2020-2021 wet season and subsequent wet seasons until work commences. Work for this encroachment 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. Culvert sizing calculations, design plans, and construction details for the second crossing have not yet been provided. Work shall not commence until CDFW has reviewed and accepted stream crossing design plans as stated in Sections 2.50 and 3.1 of this Agreement. Project activities at STX-2 shall require pre-construction surveys by a Designated Biologist if surface water is present one week before construction or becomes present during construction. Permittee disclosed additional features of interest (Table 2). The Notification states the pond is in good condition and meeting current performance standards. Existing features disclosed in the Notification, but not included as 1602 projects with fees, are not covered under this Agreement. If maintenance and/or repairs become necessary, that work must be covered by a major amendment or a separate Notification if the work will result in substantial alteration of the bed, bank, or channel of a stream. The Notification also discloses the use of a well located at Lat/Long 39.2560, -123.1617. 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. 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.
