<br />G. STEVE LOWRY <br /> <br />Page 2 <br /> <br />drawings, specifications, cost estimate, design analysis, engmeering considerations and <br />instructions for field personnel) in a format acceptable to the COE, the City of Phoenix and <br />the Maricopa County Flood Control District. Construction is scheduled for 2001 at a cost <br />between $IOM and $20M. <br /> <br />Project Manager for the Green Mountain drainageway planning and design for the City of <br />Lakewood, Colorado. Mr. Lowry managed final design of a flood control project comprised <br />of one low diversion dam, one high-hazard jurisdictional 40-foot high earthen dam, one <br />connecting channel for 185 cfs and associated outlet and storm sewer piping. The study goal <br />also considered restoration of disrupted land areas to natural conditions taking into account <br />revegetation, erosion control, environmental and hazardous material surveys. The stormwater <br />facilities were designed using Best Management Practices to protect water quality. He <br />performed HEC-I analysis to determine inflow design flood and also evaluated several <br />methods to provide overtopping protection to the embankment given site restrictions for the <br />spillway. Two well-attended public meetings were held in addition to a neighborhood <br />meeting on site. A Cost/Benefit analysis was provided based on removal of floodplain <br />damages using the Average Annual Damage methodology. Mr. Lowry assisted the City in <br />evaluating sources of construction funds. <br /> <br />Project Engineer for a water supply study for the City of Durango, Colorado. Mr. Lowry <br />provided analysis of an existing 5 mgd pump station and booster station with a total of 500 <br />feet of head and made recommendations to increase performance. He prepared preliminary <br />design for a new pump station and intake from the Animas River and also assisted in the <br />review of dam sites, performed an hydraulic analysis of the 9-mile long, 5.8 mgd Florida <br />pipeline, along with a review of alternative intake locations, and prepared cost estimates of <br />alternatives. <br /> <br />Project Manager for an ongoing consulting contract with the Church Ditch Company in <br />Denver, Colorado. As the Engineer for the Ditch, responsible for the review of designs for <br />modifications to the Ditch. The Ditch is a former agricultural supply canal now used to <br />convey raw water to the principal storage reservoir for over 200,000 people. Prepare <br />conceptual designs of hydraulic control structures, including flow limiters, inverted siphons, <br />realignments and diversions. <br /> <br />Project Manager for the Signal Ditch Diversion preliminary and final design for the City of <br />Thornton. This project required construction of a new diversion structure on the Signal <br />Irrigation Ditch and the building of a new channel to convey flows to the existing Eastlake # <br />3 Reservoir. The design included an analysis of sediment and debris in the Ditch and <br />development of a method to minimize the impact on receiving waters of Reservoir #3. The <br />design minimized the disturbance of adjacent properties through which the new channel <br />passes. These properties include urban landscapes as well as wetland landscapes. <br /> <br />Project Manager for technical design and management of design and rehabilitative projects <br />on the Colorado Canal in eastern Colorado. The project involved design of drop structures, <br />Parshall flumes up to 35-feet wide, sluices and embankments. <br /> <br />f,W)f'\'TGOlVlERY WATSON <lIJ> <br />
