Schatz Demonstration Tree Farm Road Improvement Project (Lake or Streambed Alteration Agreement No. EPIMS-HUM-58743-R1C)

The Schatz Demonstration Tree Farm Road Improvement Project involves the replacement of four existing 18-inch diameter culverts with minimum 24-inch diameter culverts to improve water flow and reduce erosion risks along a road corridor in Humboldt County, California. Each culvert replacement at the specified geographic coordinates includes excavation, removal of the old structure, installation of the new culvert, backfilling and compaction of native material, and application of rock armor at inlets and outlets to stabilize the embankments and prevent sedimentation. One of the four crossings also requires rock slope protection in addition to inlet and outlet armor due to higher erosion potential. The work is scoped exclusively to these four encroachments and does not extend to broader roadway improvements. The project is administered by the California Department of Fish and Wildlife, Region 1, under Lake or Streambed Alteration Agreement No. EPIMS-HUM-58743-R1C, with Jonathan Hollis listed as the primary point of contact for environmental compliance and coordination. The project was posted as a forecast on July 29, 2026, indicating it is in the planning or pre-procurement phase prior to formal solicitation.
