<br />Project- Specific Experience
<br />Project Engineer, Shadow Rock Detention Basin Urban Water
<br />Recovery, Rancho Santa Margarita, CA, Trabuco Canyon Water
<br />District, 2013 -2014, $402K: Responsible for performing hydrologic and
<br />hydraulic analyses for the tributary watersheds to Shadow Rock Detention
<br />Basin for the 2 -year and 100 -year return period design storms using the
<br />Advanced Engineering Software package (AES). The analyses included
<br />watershed delineation, rational method modeling, hydrograph
<br />development, and basin routing of the selected design storms. Also
<br />responsible for pump selection calculations and design for a low flow 80
<br />gpm pump and a high flow 215 gpm pump to convey water from the
<br />detention basin to a reservoir in the District's reclaimed water supply
<br />system.
<br />Project Engineer, Orange Park Acres Well No. 1 Wellhead
<br />Facilities, Orange, CA, Irvine Ranch Water District, 2013 -2014,
<br />$5.2M: Responsible for site civil engineering, pump selection and design
<br />for a 2,000 gpm groundwater well, booster pump, and chloramine
<br />disinfection facility that will supply treated groundwater to the Orange
<br />Park Acres service area to meet domestic water demands. The pump
<br />building and calculations were designed to accommodate a future
<br />doubling of the production capacity to 4,000 gpm upon addition of a
<br />second supply well. Developed engineers estimate of probable costs.
<br />Prepared permitting documents and coordinated to obtain approvals from
<br />Orange City Fife Department and City of Orange Water Department.
<br />Project Engineer, Ttampas Lake Reservoir and Dam, Orange
<br />County, CA, Rancho Mission Viejo, 2013 -2014, $51M: Responsible for
<br />preparing plans, reports, design calculations, and construction cost
<br />estimates for converting an existing tailings storage dam to a recycled
