AdrianLee, PE TechnicalStudies/Reports/Hydraulic WO)fie than 14 years of professional experience in the developmentoTconceptual studies for domestic water and reclaimed water systems, as well as final design for water distribution and transmission systems, sewer conveyance facilities, and utility relocations. EXPERIENCE Main Plant Water Master Plan, City of Fullerton, CA. 2021. Project Engineer/Hydraulic Modeler for the modeling and hydraulic analysis of the City's Main Plant, consisting of groundwater wells, a reservoir, and a pump station. Utilized the City's Infowater model and analyzed potential future scenarios to provide recommendations for pipeline size and configurations. Analysis was performed in conjunction with the ongoing design of a PFAS Water Treatment Plant to be located at the Main Plant, and the analysis took into consideration the proposed Treatment Plant configurations and constrains. Education: BS, Civil Engineering, University of California, Irvine, 2007 Registrations/Certifications: Professional Civil Engineer, California, No. 79032, 2011 Professional Affiliations: American Society of Civil Engineers American Water Works Association Office Location: San Dimas, CA Years of Experience: 14 Years with Tetra Tech: 14 Hawthorne Boulevard Transmission Hydraulic Analysis, City of ' Torrance, CA. 2016. Project Engineer to assess impacts of various options to connect a 12-inch 4,300 foot long transmission main. Computer modeling utilized H2O Map and evaluation included water age, fire flow, pressure, and other criteria. Recommendation was for a very simple option which resulted in the lowest construction cost. Inglewood Water Master Plan 2014, City of Inglewood, CA. 2015. Design Engineer/Hydraulic Modeler for the modeling and analysis of City's potable water system. Developed a calibrated model of the City's water system in InfoWater, utilizing the City's GIS data. Assessed the system based on criteria for fire flow, pressure, velocity, and water age. Also assessed the City's operational storage and fire storage requirements. Provided recommendations for optimizing operations, and developed a capital improvements program. Beaudry Terrace/Glorietta Park Pressure Surge Analysis, City of Glendale, CA. 2015. A report to analyze occurrences of surge and main breaks in the Beaudry Terrace area of the 1666 Zone in the City of Glendale's water system. Updated the City's H2ONET model and provided fire flow evaluations of the Beaudry Terrace area. Also analyzed possible pipeline connections to improve fire flow in the Verdugo 1666 Zone. Total Dissolved Solids Analysis, City of Torrance, CA. 2012. Design Engineer to assess impacts of supplying up to 5,000 gpm from North Torrance Well Field. This new source required blending due to high Total Dissolved Solids and Manganese. Developed H2ONET TDS contour map under several scenarios to identify distribution system blending of TDS and Manganese. Identified impacts of various improvements to dispersion of TDS. Condition Assessment of CMP Storm Drains, City of San Diego, CA. 2012. Design Engineer for a large storm drain assessment project for the City of San Diego, for which over 11.5 miles of CMP storm drain from 8-inch to 120-inch was inspected and assessed. Video inspection of the City's CMP storm drains was performed by a subcontractor and the video footage with reports was delivered to Tetra Tech. Each pipe was individually assessed as to condition, specific types and severity of defects discovered, and recommendations for repair were made based on the engineer's analysis. The project was divided into five phases with each phase providing a summary of defects as well as recommendation for rehabilitation or replacement. The report willbe used to prioritize maintenance and repair of the entire storm drain conveyance system. TETRATECH
