Glenn County Road 305 Bridge Replacement Project, Bridge No. 11C-0091, Federal Aid No. BRLO-5911(056)

The purpose of this addendum is to document that new mitigation measures have been incorporated into the project. The County of Glenn Public Works Agency (County) received comments from the California Department of Fish and Wildlife (CDFW) in response to the 2023 Initial Study and Mitigated Negative Declaration (IS/MND) for the above referenced project. The County completed an update to the project’s Natural Environment Study (NES) in order to fully address CDFW’s comments and incorporated these updates into the revised IS/MND. As a result of the updated NES, The California Department of Transportation (CalTrans) has requested that conservation measures for northwestern pond turtle be incorporated into the project as a “show of good faith, to further the protection and recovery of the species, and in anticipation of any future listings”. In response to the request made by CalTrans, the County has revised the 2026 NES update to include northwestern pond turtle as one of the considered species. The County has determined that there has been no new information that has been identified that would result in a significant impact on the environment that was not discussed in the previous IS/MND. Given the absence of typical habitat and the low likelihood of northwestern pond turtle being present in the project area even temporarily, the County would not consider the project as having a significant impact on northwestern pond turtle. It is also noted that the species was not included in the CDFW comments to the 2023 IS/MND or in the original NES report that was approved by Caltrans in 2021. The County has determined that the potential impact to the Western Pond Turtle is less than significant and the measures being incorporated into the project even further reduce the potential for any impacts. No compensatory mitigations measures are proposed with this addendum.
