Consulting Services Agreement between City of San Leandro and 6 November 2023 Schaaf and Wheeler for TCD Design Exhibit A – Page 17 of 27 • Should any device result in flooding or cause impacts to upstream hydraulic grade or to the pump stations, such as excessive cycling, alternatives will be considered, or mitigation may be proposed. Mitigation may include altering pump station set points, installing longer weirs, installing diversion piping or placing devices offline. Up to two concept drawings for each location would be developed. Should ACFCD require the installed TCDs to have no hydraulic impact during design storm events, significant and costly design measures would be required for compliance. Task 1.4 Conceptual Cost Estimates. This task involves the preparation of construction cost estimates for the proposed alternatives. Task 1.5 Basis of Design Report. A Basis of Design report would be prepared to summarize, synthesize, and document information obtained from the above tasks. This report would include the following items: • An evaluation of possible alternatives and a discussion of their pros and cons; including such issues as cost, complexity, constructability and maintenance. • Recommended alternatives for each location and an overall scope of work that would achieve regulatory compliance. • An opinion of regulatory and jurisdictional permit requirements; including California Environmental Quality Act (CEQA), environmental permits, Caltrans, ACFCD and EBRPD. One meeting with each agency is anticipated. Meetings would occur after hydraulic impacts analysis is completed. Includes Biological Resources Technical Report in support of CEQA. • Identify additional work tasks needed to complete the project that are not already addressed by the current contract and scope of work; such as: geotechnical investigations, structural design, ROW or easement acquisition, additional permits needed, or utility locating and coordination. (The City will complete any identified right of way negotiations, agreements, and appraisals as necessary.) A draft report would be revised to a final version after review and input by the City. Consultant to meet with City to review and select project alternatives to continue into design. If a location is determined to be infeasible, Consultant will work with the City to identify a more feasible location within the same watershed Phase 2 – Construction Bid Documents: Task 2.1 Project Management and Meetings This task includes consultant costs for project management and meetings with City staff as needed to complete construction bid documents. Consultant to allow for a minimum of four (4) on-site progress and coordination meetings. Task 2.2 Field Research This task involves collecting the necessary field data for design and includes the following items: DocuSign Envelope ID: B1AAF39E-9A9A-4491-B2A9-FBDFD1CF7A5E
