Shelterwood Crossings Project (Notification of Lake or Streambed Alteration, No. EPIMS-SON-52695-R3)

The California Department of Fish and Wildlife has authorized the Shelterwood Crossings Project through a Lake and Streambed Alteration Agreement designated as EPIMS-SON-52695-R3, issued under Section 1602 of the Fish and Game Code. The project involves the removal and replacement of four existing culverts with new corrugated metal pipe culverts sized to improve flow conveyance and reduce erosion across five unnamed tributaries to Bearpen Creek in Sonoma County. One culvert will be replaced with a rock ford at map point 1.11, including removal of existing concrete wingwalls, while another rock ford at map point 1.18 will be reconstructed within its existing footprint without creating net new impact. Work is scheduled to occur only during dry conditions with no surface water present, using existing roads for access and staging. The project will result in approximately 236 square feet of permanent riparian habitat impact, including 100 square feet from culvert extensions and 136 square feet from new riprap, with an additional 2,460 square feet of temporary disturbance. Five riparian trees will be removed as part of the work. The project qualifies for a categorical exemption under Title 14, Section 15302 of the California Code of Regulations, as it involves the replacement of existing structures with substantially equivalent function and capacity, minimizing environmental disruption. No federal procurement clauses, contract values, pricing details, or formal solicitation elements are included, as this is a regulatory environmental authorization rather than a traditional federal contract. The agreement is administered by the California Department of Fish and Wildlife, Region 3 - Bay Delta, with primary oversight provided by Environmental Scientist James Hansen and Environmental Program Manager Craig J. Weightman. The proponent, Shelterwood Collective, is responsible for implementing all work in compliance with the approved plan and regulatory standards. All activities are confined to the specified locations along Bearpen Creek tributaries, with no delivery, shipping, packaging, invoicing, or payment terms outlined, reflecting the nature of the document as an environmental permitting instrument rather than a procurement contract.
