Deliverables <br /> ■ H/H Modeling Technical Memorandum <br /> ■ Calibrated H/H Model <br /> ■ LOS Maps for Existing System and corresponding GIS shapefile <br /> ■ Map, and corresponding GIS shapefiles,showing condition ranking for pipes and structures <br /> ■ Criteria and methodology for condition assessment scoring, likelihood of failure, and <br /> consequence of failure <br /> ■ Draft Chapter 3 —Sewer System Evaluation <br /> ■ Agenda and meeting minutes for the three workshops under this task <br /> Assumptions <br /> ■ Model platform is InfoSWMM. City to provide existing copy of hydraulic model, including <br /> those recently developed by other consultants for the PGSF Plan and the Sewer 0 project. <br /> ■ Model update assumes model includes City's existing 35 major regulators, 33 lift stations, <br /> and 13 permitted outfalls. Budget includes one (1) hour review of each structure plus <br /> budget to compare hydraulics to City GIS. It is assumed that these structures are <br /> appropriately represented based on previous conversations with City staff. If it is <br /> determined from model review that structure data is insufficient then the Consultant will <br /> alert City staff to request more information. Up to sixteen (16) hours are assumed for <br /> additional structure review and update. <br /> ■ City to provide climate change information from University of Washington Climate Impact <br /> Group (UW). <br /> ■ Model will be calibrated at up to twenty-five (25) locations for up to three (3) storm events <br /> at each location, if available from the available data. <br /> ■ Deficient pipes will be sized for the 20-year planning horizon per established planning <br /> criteria from Task 4. <br /> ■ System LOS will be defined using the design rainfall timeseries in a methodology similar to <br /> that used in the 2014 Comprehensive Sewer Plan. <br /> ■ Intermediate (10-year) analysis to be used for CIP phasing. Model scenarios will not be <br /> created for the 10-year planning horizon because no significant land use or population <br /> changes are anticipated over that time horizon.. <br /> ■ Budget estimate for capacity analysis assumes 60 deficiencies, which is approximately <br /> three deficiencies per sewer basin. <br /> ■ The consultant is not tasked with reviewing CCTV data. <br /> City of Everett MURRAYSMITH 2023 Comprehensive Sewer Plan <br /> March 2021 15 <br />
