Adrian Lee, PE <br />Task Engineer —Technical Studies/Reports <br />Hydraulic Modeling <br />Mr. Lee has more than 11 years of experience in the development of <br />conceptual studies for domestic water and reclaimed water systems, as <br />well as final design for water distribution and transmission systems, <br />sewer conveyance facilities, and utility relocations. <br />EXPERIENCE <br />Hawthorne Boulevard Transmission Hydraulic Analysis, City of <br />Torrance, CA. Design Engineer to assess impacts of various options to <br />connect a 12-inch 4,300 foot long transmission main. Computer modeling <br />utilized H2O Map and evaluation included water age, fire flow, pressure, <br />and other criteria. Recommendation was for a very simple option which <br />resulted in the lowest construction cost. <br />Beaudry Terrace/Glorietta Park Pressure Surge Analysis, City of <br />Glendale, Glendale, CA. A report to analyze occurrences of surge and <br />main breaks in the Beaudry Terrace area of the 1666 Zone in the City of <br />Glendale's water system. Updated the City's H2ONET model and <br />provided fire flow evaluations of the Beaudry Terrace area. Also analyzed <br />possible pipeline connections to improve fire flow in the Verdugo 1666 Zone. <br />Education: <br />B.S., Civil Engineering, <br />University of California, Irvine, <br />2007 <br />Registrations/Certifications: <br />Professional Civil Engineer, <br />California, No. 79032, 2011 <br />Professional Affiliations: <br />American Society of Civil <br />Engineers <br />American Water Works <br />Association <br />Water Environment Federation <br />Office Location: <br />San Dimas, CA <br />Years of Experience: <br />11 <br />Years with Tetra Tech: <br />11 <br />Sewer System Master Plan, City of West Hollywood, West Hollywood, CA. Project Engineer for developing <br />a hydraulic model of the sewer system to evaluate system capacity and performing a structural evaluation of the <br />system based, in part, on manhole inspections and television videotapes of the pipelines. Prepared a <br />comprehensive capital improvement, preventive maintenance program, and master plan report. <br />TDS Analysis, City of Torrance, Torrance, CA. Design Engineer to assess impacts of supplying up to 5,000 <br />gpm from North Torrance Well Field. This new source required blending due to high Total Dissolved Solids and <br />Manganese. Developed H2O Net TDS contour map under several scenarios to identify distribution system <br />blending of TDS and Manganese. Identified impacts of various improvements to dispersion of TDS. <br />High Zone Recycled Water Reservoirs, City of Chino Hills, Chino Hills, CA. Project Engineer for the <br />feasibility, design and construction management of a 0.5 MG and a 2.0 MG recycled water reservoirs located at <br />two separate sites. The design included access road improvements, recycled water transmission mains, and <br />site improvements for the two above -ground steel tanks. <br />Condition Assessment of CMP Storm Drains, City of San Diego, CA. Design Engineer for a large storm <br />drain assessment project for the City of San Diego, for which over 11.5 miles of CMP storm drain from 8-inch to <br />120-inch was inspected and assessed. Video inspection of the City's CMP storm drains was performed by a <br />subcontractor and the video footage with reports was delivered to Tetra Tech. Each pipe was individually <br />assessed as to condition, specific types and severity of defects discovered, and recommendations for repair <br />were made based on the engineer's analysis. The project was divided into five phases with each phase <br />providing a summary of defects as well as recommendation for rehabilitation or replacement. The report will be <br />used to prioritize maintenance and repair of the entire storm drain conveyance system. <br />TETRA TECH <br />
