Vacaville Parkway Water Crossing Improvements Project (Notification of Lake or Streambed Alteration, No. EPIMS-SOL-58268-R3).

The Vacaville Parkway Water Crossing Improvements Project, identified by Notification No. EPIMS-SOL-58268-R3, is a Lake and Streambed Alteration Agreement executed by the California Department of Fish and Wildlife with the Pacific Gas and Electric Company. Located at two unnamed tributaries to Laguna Creek in Solano County, California, the project involves the replacement of existing corrugated metal pipe culverts and the new construction of rip-rap aprons and rock slope protection at two separate locations. The project is categorized as a Class 2 statutory exemption under the California Code of Regulations because it replaces existing structures with new ones that maintain substantially the same purpose and capacity. The scope of work includes significant vegetation management, such as the removal of three native trees—specifically two bay laurel trees and one toyon—along with a dead bay laurel at Crossing 2. Additionally, the project requires the removal of shrubs within chamise chaparral vegetation, including toyon, coyote bush, and sumac, as well as the trimming of branches over drainages to facilitate construction access. Environmental impacts are quantified as a permanent impact to 0.076 acres (273 linear feet) of stream habitat and the placement of 447 cubic yards of new fill associated with the rock slope protection. The agreement was finalized on November 26, 2025, pursuant to Section 1602 of the Fish and Game Code.
