REV: 10-15-2021 SK EXHIBIT “A” SCOPE OF SERVICES AND FEE SUMMARY OF CURRENT WORK The City of Redwood City is considering a proposed development project at 750 Bradford Street that includes proposed residential and commercial developments. The proposed project is located on the parcel(s) immediately across the street (south) from the Bradford Pump Station. The City is interested in gaining a refined understanding of the culvert and the site near the proposed development. This scope of work includes evaluation of the capacity of the creek relative to the 100-year recurrence storm event, as well as handling tidal influence, sea level rise, and FEMA flood hazards. Consultant will perform the Services described in the following section. SCOPE OF SERVICES TASK 1 – Project Management Consultant will provide the appropriate project management for this project, including 2 meetings, meeting notes, invoicing, and management of budget, schedule, and deliverables. Deliverable(s): Meeting minutes, invoicing. TASK 2 – Redwood Creek Drainage Structures Assessment Consultant will review the hydraulic model and analysis of the Redwood Creek including the existing twin 8’H x 16’W culverts under Bradford Street (immediate west of Main Street) in the City’s ICM model. This model was developed as part of the Eastern Low- Lying Area (ELLA) Drainage Master Plan by Consultant in 2017. Based on the review, Consultant will provide an assessment of the existing culverts capacity, the City’s required culvert capacity, and the necessary improvements to bring the existing culverts to the City’s requirements. The existing capacity will be based on the model results and may consider required freeboard to either the top of the culvert or to adjacent development grades, as appropriate. The required capacity will be based on City, local, and/or federal requirements. To determine the necessary improvements, Consultant will identify and model at least two alternatives for improving the capacity. The alternatives may include adding an additional culvert or increasing the height or width of the existing culverts. Deliverable(s): Twin culvert assessment memorandum TASK 3 – Floodplain and Sea Level Rise Assessment Consultant will review the ELLA Drainage Master Plan, the effective FEMA Flood Insurance Study, and the State of California Sea-Level Rise Guidance 2018 Update. Based on the review, Consultant will identify the existing flood risk at the project site and the projected flood risk at the project site. The projected flood risk will reflect 50 years ATTY/AGR.2021.260/Wood Rodgers, Inc. (750 Bradford Street) (Page 11 of 14)
