<br />Village Park Recycled Water Facilities, Olivenhain Municipal
<br />Water District, CA. Project Manager for alternatives evaluation,
<br />PDR, and PS&E for design of 35,500 feet of 4"-12" PVC and fusible PVC
<br />pipe, an 1,200-gpm pump station (using prefabricated station), flow
<br />metering facilities, and modifications for conversion of existing 1.0-MG
<br />water tank to recycled water operation including addition of potable
<br />makeup water system with flow control and air -gap. The pipelines are
<br />located in busy thoroughfares, residential streets, and fronting schools
<br />and businesses. Services included extensive utility agency and City of
<br />Encinitas coordination and hydraulic analysis of operational interface
<br />between Olivenhain Municipal Water District and San Elijo Joint Powers
<br />Authority recycled water systems, support for Coastal Development
<br />Permit from City of Encinitas, and bid and construction phase support.

<br />Diego, CA. Task Manager for civil design of water storage facility
<br />comprised of two 29-MG partially buried basins to replace existing
<br />outdated structures. The project includes 2,200 feet of 54"- 84"welded
<br />steel inlet and outlet pipes, inlet and outlet structures, flow meters in
<br />buried vaults, 200feet of42"RCP overflow piping, basin drain system
<br />with 16"piping, underdrain piping, and a barrier drain system to
<br />address local groundwater. Also providing bid and construction phase
<br />support services.
<br />La Jolla View Reservoir and Pipeline, City of San Diego, CA.
<br />Project Manager responsible for PDR and PS&E for 3.1-MG reservoir,
<br />3,000 feet of 30"welded steel pipe, and demolition of two outdated
<br />reservoirs. Reservoir is comprised of prestressed concrete tank that is
<br />fully buried with limited surface features. Project includes extensive
<br />habitat restoration and public outreach support due to the tank location
<br />in a scenic, hilltop park in the coastal La Jolla area.
<br />Rock Springs Sewer, Vallecitos Water District, CA. Project Manager
<br />for the design of 2,700 feet of 12"-15"gravity sewer (with trenchless
<br />construction section) through environmentally sensitive corridor.
<br />Project included slip -lining to rehabilitate one segment of 8" pipe,
<br />environmental compliance (IS/MND preparation), and coordination with
<br />homeowners to select alignment that minimized impacts to HOA park.
<br />Flagler Wells, Elsinore Valley Municipal Water District, CA.
<br />Project Manager for design of pumps and associated appurtenances
<br />to equip two groundwater wells for delivery of raw water to Ag Line
<br />system. Project includes 800-gpm vertical turbine pumps, motor control
<br />centers, discharge pipelines to connect wells to distribution system, and
<br />pump -to -waste pipelines that outlet to the adjacent Temescal Canyon
<br />Wash. Services include engineering support during construction.
<br />Miramar Pump Station Rehabilitation/Replacement Study,
<br />San Diego County Water Authority, CA. Project Manager for an
<br />evaluation of various alternatives to either rehabilitate, upgrade, or
<br />replace the aging 100-cfs pump station that delivers treated water from
