<br />Flores No. I Reservoir is a rectangular semi -buried concrete masonry unit (CMU) water tank with a capacity of 0.3 MG. It
<br />measures approximately 82 feet by 42 feet with a depth of 15 feet. The reservoir has a wooden roof structure with skid
<br />mounted vertical turbine booster station located on top of the roof at the rear of the tank. Recent inspection showed that the
<br />roof reservoir is failing and needs replacement. Concerns regarding cracks in the concrete (cinder block) walls indicate that
<br />significant work will be required to reinforce the existing structure before re -roofing with a new aluminum roof and
<br />remounting the vertical turbine pumps.
<br />Reynolds Ranch, City of Vacaville, CA 2015 — Structural Engineer for a preliminary design report for a new prestressed
<br />concrete 0.53 MG reservoir and 490 gpm booster pump station. The PDR evaluated alternative configurations, layout,
<br />operations, geotechnical conditions, seismic constraints, community impacts, and environmental issues. Pump station
<br />design will incorporate a 50 hp two -pump booster station with motor control center, standby generator, and
<br />instrumentation. Permitting and assistance during bidding and construction was also provided.
<br />Structural and Seismic Evaluation Storage Reservoirs, Montecito Water District, Montecito, CA 2015 — Structural
<br />Engineer and Team Lead for professional engineering services to conduct condition assessments, inspections,
<br />investigations, perform testing and provide structural and seismic analysis of nine District water storage reservoirs with a
<br />combined volume of 11.5 million gallons at full capacity. (9 Reservoirs - (5) Rectangular Predominately Buried Concrete,
<br />(3) Circular above Ground Concrete and (1) Circular above Ground Steel reservoir). Deficiencies identified will be
<br />presented with prioritized alternatives for repair(s), retrofit or replacement to ensure these facilities continue to operate and
<br />provide water following a seismic event. The District provides potable water to about 4,360 customer accounts that use
<br />approximately 5.5 million gallons of water per day.
<br />Memorial Park Reservoir, City of Santa Monica, CA, 2010 — Structural Project Engineer for a feasibility report for two
<br />buried concrete tanks, a 5 MG reclaimed water tank and a I MG potable water tank, and a buried concrete pump station.
<br />The report focused on minimizing disruption to the park facilities while maximizing the storage capacity of the tanks. The
<br />preparation of the report involvedthe investigation of construction of conventionally reinforced rectangular tanks and
<br />prestressed circular concrete tanks, and the use of cantilevered and tie -back shoring. Comprehensive cost estimates,
<br />conceptual drawings and detailed discussions of six different alternatives to help the City select the design concept that best
<br />meets the project requirements.
<br />Reservoir Seismic Vulnerability Evaluations, City of Ontario, CA, 2008 — Structural Project Engineer for the seismic
<br />evaluations on ten of the City's 12 water storage reservoirs among which included the 13th Street Reservoirs. The purpose
<br />of the evaluations was to determine what improvements are necessary for each reservoir in order to meet current seismic
<br />design standards, as well as the estimated cost of the improvements (engineering design, construction inspection, and
<br />construction). The 10 reservoirs included six buried flat bottom rectangular concrete reservoirs, two above grade flat
<br />bottom circular reservoirs (one concrete, one steel) and two hopper bottom reservoirs with wood framed roofs.
<br />3.1 MG Reservoir Seismic Strengthening, City of El Segundo, CA, 2010 — Structural Project Engineer for the
<br />preparation of preliminary and final design construction plans, specifications and cost estimates for the seismic retrofit of
<br />an existing 3.1 MG concrete potable water storage tank, originally constructed in 1948. The seismic strengthening included
<br />the addition of reinforcing steel and shotcrete to the exterior walls, plywood roof sheathing and structural steel shear
<br />transfer frames around the tank perimeter between the roof and the wall shell. Safety upgrades included the design of new
<br />roof mounted guard railing. Structural observations, special inspection by a deputy inspector and material testing were
<br />provided as part of Tetra Tech's construction phase services.
<br />Nohl Canyon Tank, City of Anaheim, CA, 2010 — Served as the Project Structural Engineer for the design of a 10 MG
<br />prestressed concrete reservoir located within the existing footprint of a 60 MG dam -embankment reservoir, including the
<br />abandonment of existing facilities, modifications to the existing inlet/outlet piping, and revisions to the existing disinfection
<br />system. The design also included site grading, drainage, and access.
<br />Seismic Retrofitting of Seven Steel Water Storage Tanks, City of San Buenaventura. CA, 2000 — Served as the Lead
<br />Design Engineer to perform seismic retrofit design for both the tank structure and piping for seven steel water storage
<br />tanks. Retrofit improvements included installation of seismic uplift anchors and concrete ring beam footings, wall shell
<br />reinforcing bands, and installation of flexible pipe couplings and isolation of drain piping and overflow piping from buried
<br />piping.
