The Mayor and City Council are asked to consider authorizing and executing amendment one to the Contract for Professional Services with HDR Engineering, Inc. to complete the engineering design for W.O. 18-22: Leavens Reservoir Expansion and Zone 1 Improvements. The initial Contract which was Phase I covered the preliminary evaluation and design, survey, and geotechnical information. The amendment will provide engineering services for Phase II which will complete final design and bidding and construction phases.
