Scope of Work Preparation of Plans,Specifications and Estimates Sunol Boulevard/I-680 Improvements Project August 21,2023 • Construction monitoring as defined in the Paleontological Mitigation Plan and measures to protect California tiger salamander, California red-legged frog, Alameda whipsnake, and other special-status species. In addition, the ECR will specify timing and responsible parties for each item. Task 8.4 Environmental Permits AECOM will prepare permit applications including detailed project description, area and quantities of fill within streambed, types of fill, methods of diversion if needed, and types of equipment used to do all in-channel/floodplain work. If needed, AECOM will assist in coordination with, and attend, one interagency meeting with the permitting agencies. As part of these activities, AECOM will perform GIS analysis of sensitive resources and project impacts to develop impact acreages for each permit application. Up to two revisions of the GIS analysis and related permit application figures are assumed, to address ongoing design changes during PS&E. AECOM will prepare applications for the following permits. • CDFW Streambed Alteration Agreement Notification(Section 1602 permit) In accordance with CDFW requirements on other recent projects, a Woodrat Relocation Plan and an On-site Revegetation and Restoration Plan will be prepared as attachments. As part of the application and to support preparation of the Plant Removal Plan sheets,the tree inventory prepared during PA&ED will be reviewed for updates. • CDFW Incidental Take Permit(for California tiger salamander and Alameda whipsnake). • Section 404 permit for placement of fill in United States Army Corps of Engineers (USACE)jurisdictional wetlands, as identified in the project's jurisdictional delineation prepared during PA&ED. Although the area of impacts to jurisdictional waters identified in the IS/MND is extremely small, USACE verification of the delineation is pending,and the extremely wet conditions of 2023 may have increased the size of waters in the project footprint. The need for a Section 404 permit is therefore assumed. A Nationwide Permit 414 is expected to be appropriate. • Section 401 Water Quality Certification and/or Report of Waste Discharge from the San Francisco Regional Water Quality Control Board(RWQCB). AECOM will prepare materials to support the current RWQCB 401 Certification Rule process (as amended in June 2022), and attend one pre-application meeting with RWQCB staff. AECOM will reconcile agency review comments on the environmental permit applications, prepare updated permit applications as required, and provide applications to Caltrans to submit for regulatory agency approval. One set of revisions to each application is included. Page 32 of 42
