September 2020 General Information about this Document The California Department of Transportation (Caltrans), as assigned by the Federal Highway Administration, has prepared this Initial Study with Mitigated Negative Declaration and Environmental Assessment with Finding of No Significant Impact, which examines the potential environmental impacts of alternatives being considered for the project in Santa Barbara County, California. Caltrans is the lead agency under the National Environmental Policy Act. Caltrans is the lead agency under the California Environmental Quality Act. This document explains why the project is being proposed, what alternatives have been considered for the project, how the existing environment could be affected by the project, the potential impacts of each alternative and the proposed avoidance, minimization and/or mitigation measures associated with the project. The draft Initial Study with Proposed Mitigated Negative Declaration and Environmental Assessment was initially circulated to the public for 35 days between December 13, 2019 and January 17, 2020. The draft Initial Study with Proposed Mitigated Negative Declaration and Environmental Assessment was then revised to address new project information and to address public comments pertaining to the City of Goleta’s planned multipurpose path project that was collected during the initial public review period. A revised version of the draft Initial Study with Proposed Mitigated Negative Declaration and Environmental Assessment was circulated to the public for 44 days between April 13, 2020 and May 27, 2020. Public comments received during this review period are presented in Appendix I, Comment Letters and Responses.

This Finding of No Significant Impact is based on the attached Environmental Assessment, which has been independently evaluated by Caltrans and determined to adequately and accurately discuss the need, environment issues, and impacts of the proposed project and appropriate mitigation measures. It provides sufficient evidence and analysis for determining that an Environmental Impact Statement is not required. Caltrans takes full responsibility for the accuracy, scope and content of the attached Environmental Assessment and incorporated technical reports. The environmental review, consultation, and any other actions required by applicable Federal environmental laws for this project are being, or have been, carried out by Caltrans pursuant to 23 U.S. Code 327 and the Memorandum of Understanding dated December 23, 2016, and executed by the Federal Highway Administration and Caltrans. San Jose Creek Bridge Replacement iii This page left intentionally blank San Jose Creek Bridge Replacement iv SCH Number: 2019129047 Mitigated Negative Declaration Pursuant to: Division 13, Public Resources Code Project Description The California Department of Transportation (Caltrans) proposes to replace the existing northbound and southbound San Jose Creek Bridges (Bridge Number 51- 0163 R/L) which are in Santa Barbara County on U.S. Route 101 at post mile 21.6. The new bridge design would be a single-span bridge. Building the new bridge would involve the following: removing the existing bridge structure and building a new bridge structure, removing the existing slope pavement on the creek banks, installing rock slope protection, replacing traffic barriers to meet current safety standards and minor earthwork. The project would affect nearby vegetation. U.S. Route 101 is a major north-south highway that serves California, Oregon, and Washington. Within the project limits, U.S. Route 101 consists of a six-lane freeway, with three lanes in each direction. The project is in an urban environment, which consists of residential, commercial and industrial land uses. Determination Caltrans has prepared an Initial Study for this project and, following public review, has determine from this study that the project would not have a significant effect on the environment for the following reasons: The project would have no effect on existing or future land use, coastal resources, wild and scenic rivers, parks and recreation facilities, farmland, timberland, growth, community character and cohesion, environmental justice, utilities, cultural resources, paleontological resources, and mineral resources. The project would have less than significant effects on visuals/aesthetics resources, emergency systems/services, traffic and transportation, wildfire hazards, hydrology and floodplains, geology and soils, greenhouse gasses, hazardous materials, air quality, and noise levels. The project would have no significant adverse effect on water quality or biological resources because the following mitigation measures will be implemented: Water Quality Measures · Project-related work in the creek will not be conducted during the wet season. · A water diversion/dewatering management plan will be implemented to allow for work in the wetted channel. · Appropriate Best Management Practices for water pollution control, erosion control and stormwater management will be implemented during project construction. San Jose Creek Bridge Replacement v Biological Resource Measures · Pre-construction surveys will be conducted for special-status species before removing vegetation. · Vegetation and tree removal will be kept to the minimum required for project completion. · Before project construction begins, environmental sensitive area fencing will be installed within the project site to keep construction activities out of those areas. · Biological monitoring will be conducted during various stages of project construction. · Invasive, non-native species will be controlled to the maximum extent possible. · Areas disturbed by project construction will be restored to conditions that would allow them to function as potential habitat for species. · On-site compensatory mitigation will be required for the project. Temporary impacts to wetlands and jurisdictional areas will require a 1 to 1 replacement ratio. Native plant replacement will require a 1 to 1 replacement ratio. It is anticipated that impacts to riparian trees will require a 3 to 1 replacement ratio.
