Task 204—Alternatives Evaluation and Conceptual Design 204.1 Develop Design Criteria—Develop design criteria and document City preferences for use in the alternatives evaluation, conceptual and preliminary design efforts including the following: • Reservoir seismic and structural criteria • Reservoir floor and overflow elevations • Coating systems, interior and exterior • Cathodic protection considerations • Reservoir inlet, outlet, overflow, and drain piping • Allowable leakage criteria, collection and disposal • Hydraulic mixing system • Metering and valving • Dechlorination • Access and safety systems, interior and exterior • Ventilation • Water quality sampling • Security • Lighting • SCADA/telemetry • Operations and maintenance • Yard Piping • Site Access • Reservoir type, shape, and number of reservoirs or compartments • Site grading and reservoir • Reservoir Operations and Maintenance MSA will prepare a draft design criteria and City preferences summary for City's review and input. Design criteria and preferences will then be discussed and finalized with City staff in a workshop setting. Finalized design criteria and preferences will be documented and submitted to City. 204.2 Develop and Evaluate Alternatives—Identify, describe, and evaluate up to two (2) alternatives for each of the following: • Reservoir size,type and configuration, one or two reservoirs • Valve facility style and configuration • Water transmission main replacement/rehabilitation options City of Everett MURRAY,SMITH&ASSOCIATES,INC.
