Scope of Work Preparation of Plans,Specifications and Estimates Sunol Boulevard/I-680 Improvements Project August 21,2023 agency, pursuant to 23 United States Code (USC) 327 and the Memorandum of Understanding dated May 27, 2022, and executed by FHWA and Caltrans. If the project does not receive FHWA funding, a different process would be required to obtain the federal permits/approvals for the project because Caltrans does not have the authority to approve NEPA actions or conduct federal consultation outside of the Caltrans ROW. Level of effort associated with that process would be subject to additional scope. AECOM will coordinate with Caltrans throughout the preparation, review, and acceptance of the deliverables below, and support Caltrans and City coordination with permitting agencies and mitigation providers. Unless otherwise noted, for each deliverable in this task, AECOM will prepare an administrative draft version for team review and comment, a draft for Caltrans review, a revised draft incorporating any Caltrans comments, and a final draft for Caltrans signature. Task 8.1 Technical Report Updates for NEPA Compliance/NEPA Categorical Exclusion The following items are required for NEPA clearance and to support federal permits/approvals. • Approval of Cultural Resource Findings under Section 106 of the National Historic Preservation Act. AECOM will convert the approved CEQA-only Historic Resources Compliance Report, Archaeological Survey Report, and Project Area Limits map to a NEPA/Section 106-compliant Historic Properties Survey Report, Archaeological Survey Report, and Area of Potential Effects map. • Approval of Biological Resource Findings under Section 7 of the Federal Endangered Species Act. AECOM will complete the United States Fish and Wildlife Service (USFWS) Biological Assessment that was initiated during PA&ED and perform an analysis of project lighting on species habitat, which is now required by the USFWS and California Department of Fish and Wildlife (described further below). The Biological Assessment is needed to obtain a Biological Opinion from USFWS, which in turn is needed to obtain the resource agency permits listed in Task 9.4 below. AECOM will prepare a simulation of the effect of project lighting on species habitat using AGi32 version 17.5 (Lighting Analysts Inc.) or similar software. The simulation will produce isolines that can be overlaid on habitat mapping to approximate illumination impacts at various lux values. AGi32 does not account for existing illumination from roadway traffic, topography, or obstacles in the landscape, so the isolines will be manually adjusted in GIS. Figures showing isolines with and without shielding will be produced. Page 30 of 42
