3.4 Assumptions <br /> 1. GIS layers associated with figures for this chapter and provided by the City are up-to-date and <br /> do not need to be modified or created by HDR. HDR will take existing layers and compile them to <br /> form figures for the chapter. <br /> 2. Specific system description information flagged by the City as sensitive for security purposes will <br /> not be included in project deliverables. <br /> 3.5 Deliverables <br /> 1. Updated Water System Description Chapter for CWP. <br /> Task 4 Water System Resiliency <br /> 4.1 Objective <br /> Document recent steps the City has taken to evaluate and improve resiliency in a summary format <br /> within the CWP. Update physical resiliency information for two specific facilities. Assess <br /> compliance with Section 2013 of America's Water Infrastructure Act(AWIA), which requires <br /> certification that utilities have performed or updated risk and resilience assessments using a <br /> prescribed methodology. Review the City's 2012 Water Supply Risk Assessment Study, identify and <br /> prepare an action plan for the City to undertake related to the AWIA. <br /> 4.2 HDR Services <br /> 1. Meet with City staff to review the status of recent evaluations of resiliency to natural hazards and <br /> malevolent acts. Compare available information with requirements of AWIA Section 2013 and <br /> soon-to-be-published EPA guidance. Perform a gap analysis between the City's current risk <br /> and resilience plan and the ANSI-AWWA J100 Methodology for risk and resilience. Develop a <br /> recommended gap closure plan for the City to achieve compliance. <br /> 2. Prepare a technical memorandum outlining findings and recommendations from this review. <br /> 3. Prepare a technical memorandum to identify potential capital improvements at two particular <br /> facilities based on these activities: <br /> • Perform a structural assessment of Reservoir No. 3 and the associated yard piping <br /> terminating at the three pump station. Structural assessment will include the evaluation of the <br /> as-built drawings of the reservoir and yard piping as well as a site visit to the buried concrete <br /> reservoir. <br /> • Perform an independent review of the hydraulic evaluation and preliminary design (both of <br /> which were previously prepared by others) at the Panther Creek Facility. This will include an <br /> evaluation of converting approximate 100 LF of open channel flow by connecting the <br /> upstream and downstream portions of Transmission Lines No. 2, No. 3, and No. 4 in order to <br /> pressurize the systems and provide operational redundancy through interconnections and <br /> isolation valves. <br /> Everett Comprehensive Water Plan June 12, 2019 <br /> Exhibit A—Scope of Services Page 5 of 30 <br />
