AmeriCorps Trails Improvement Project (Notification of Lake or Streambed Alteration, No. EPIMS-SON-55944-R3)

The California Department of Fish and Wildlife has issued Lake and Streambed Alteration Agreement EPIMS-SON-55944-R3 to the City of Sebastopol for the AmeriCorps Trails Improvement Project, authorizing modifications to the trail system along the Laguna de Santa Rosa in Sonoma County. The project includes installing a 48-foot-long by 8-foot-wide aluminum pedestrian bridge spanning Zephyr Creek, supported by two cast-in-place concrete abutments placed above the 100-year flood elevation and outside the bank line. A 12-inch-wide by 8-foot-long high-density polyethylene culvert will be installed beneath the trail to convey sheet flow toward the Laguna, and the work will result in 392 square feet of permanent riparian habitat impact and the removal of two riparian trees. All access and construction activities will occur via existing roads and developed trails to minimize environmental disturbance. The project qualifies for a Class 3 categorical exemption under the California Environmental Quality Act and is governed under Section 1602 of the Fish and Game Code, which regulates lake and streambed alterations. The City of Sebastopol Public Works Department, represented by Elissa Overton, is responsible for execution, while the California Department of Fish and Wildlife, through Environmental Scientist James Hansen, provides oversight. No federal contract clauses, pricing data, payment details, or formal evaluation factors are included, as this is a state environmental authorization rather than a federal procurement. The agreement was issued on June 16, 2025, and signed on June 18, 2025, with no specified start or completion dates for performance. The project site is located at latitude 38.40500° and longitude -122.81770°, with assessor parcel number 004-011-080, and no packaging, marking, or preservation standards were defined for materials.
