Caltrans is the lead agency under the California Environmental Quality Act (CEQA). The document tells you why the Project is being proposed, how the existing environment could be affected by the Project, the potential impacts of each proposed activity, and the proposed avoidance and minimization measures. The IS/ND was circulated to the public for 30 days beginning on September 2, 2020 and ending on October 1, 2020. One comment was received during the public comment period and a response to this comment is included in Appendix F. Throughout this document, a vertical line in the margin indicates changes made since the IS/ND was circulated for public review. Minor editorial changes and clarifications have not been indicated.

Determination Caltrans has prepared an Initial Study for this Project. Following public review, Caltrans has determined from this study that the Project would not have a significant effect on the environment for the following reasons: The proposed Project would have no effect on agriculture and forestry, air quality, biological resources, cultural resources, mineral resources, noise, population and housing, public services, tribal cultural resources, utilities and service systems, and wildfire. The proposed Project would have a less than significant impact on aesthetics, energy, greenhouse gas emissions, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, recreation, and transportation. 10/26/2020 Melanie Brent Date Deputy District Director Environmental Planning and Engineering Caltrans District 4 Pescadero Creek Bridge Rails Initial
