<br />La Jolla View Reservoir and Pipeline Replacement Project,
<br />City of San Diego, CA. Project Engineer for PDR and PS&E for 3.1 MG
<br />reservoir, 3,000 feet of 30"welded steel pipe, and demolition of two
<br />outdated reservoirs. Reservoir is comprised of prestressed concrete
<br />tank that is fully buried with limited surface features. Project includes
<br />extensive habitat restoration and public outreach support due to the
<br />tank location in a scenic, hilltop park in the coastal La Jolla area.
<br />Graham Reservoir and Athletic Field Project, City of Mountain
<br />View, CA. Design Engineer for an 8-MG buried concrete reservoir, pump
<br />station and athletic fields on the site of Graham Middle School. Other
<br />project elements include over 2,600 LF of new water pipeline along
<br />City and Caltrans streets, civil site improvements, utility relocations,
<br />and permitting requirements from the Division of State Architect (DSA),
<br />Fire Department, and Caltrans District 4. Major project issues include
<br />community involvement, traffic issues, conflicts with existing utilities,
<br />and coordination between the City, Mountain View Whisman School
<br />District, DSA, and the Middle School.
<br />Reservoir Rehabilitation, Vallecitos Water District, CA.
<br />Design Engineer for rehabilitation of existing steel reservoirs,
<br />including recoating, valve vault reconfigurations, and miscellaneous
<br />improvements. Prepared PS&E for various projects.
<br />Gano Reservoir Alternatives Analysis, Olivenhain Municipal
<br />Water District, CA. Design Engineer for an alternatives analysis to
<br />examine options for 6.5 MG of new potable water storage adjacent to
<br />the future Black Mountain Ranch community in San Diego. Developed
<br />and compared alternatives for twin steel and concrete tanks and
<br />partially buried single concrete tank.
<br />Calavo Pump Station Replacement and El Cajon Tank
<br />Modifications, Helix Water District, CA. Design Engineer for the
<br />replacement of an existing pump station and the replacement of an
<br />existing steel tank roof with an aluminum geodesic dome roof. The
<br />project included a new pump station building with new pumps, motors,
<br />control valves, and mechanical piping,l6-inch waterline replacement,
<br />new dome roof for the adjacent reservoir, extensive coordination
<br />and phasing to maintain service to the existing pump station and
<br />miscellaneous site improvements consisting of grading and drainage
<br />improvements. The new pump station was successfully put into service
<br />along with the retrofitted tank.
<br />Buena Vista Force Main Replacement, City of Oceanside, CA.
<br />Design Engineer for construction of approximately 9,100 LF of 24-inch
<br />sewer force main. The project included design of two tunnels; a 1,200-
<br />LF microtunnel and a 300-LF bore and jack, an alignment through
<br />residential areas, high -volume traffic areas and streets densely occupied
<br />with utilities and extensive coordination between multiple agencies
<br />and property owners.
<br />Myers -Tait Street Sewer Replacement Project, City of
<br />Oceanside, CA. Design Engineer for the replacement and upsizing of
<br />existing gravity trunk sewers in the La Salina Service Area of Oceanside.
<br />The existing sewers are currently over capacity; consequently, the
<br />replacement sewer lines must accommodate the existing flows as
<br />well as the future flows generated by new development in downtown
<br />Oceanside. Narrow residential streets, significant community impacts,
<br />and congested utility corridors added to the complexity of the project.
<br />511 Pump Station, City of Oceanside, CA. Design Engineer for
<br />preliminary design of 4.5-mgd pump station and discharge pipeline
<br />to pump from the Mission Basin Groundwater Purification Facility
<br />(RO Plant) directly to the 511 pressure zone. The preliminary design
<br />included development of the design -build contract documents,
<br />including technical specifications and 30%drawings. The pump station
<br />includes 3 vertical turbine pumps installed in an existing clearwell,
<br />control valves, flow meter, surge protection system, expansion of the
<br />existing site power capacity and a standby power system. The discharge
<br />pipeline is approximately 2,500 linear feet, to be constructed within
<br />existing City easements. The new pump station will allow the City to
<br />fully utilize the capacity of the RO Plant, increasing the volume of locally
<br />produced water, and further ensuring a safe and reliable source of water
<br />for the area.
<br />Jamacha Road 36-inch Potable Water Pipeline and 12-inch
<br />Potable Water Pipeline Replacement, Otay Water District, CA.
<br />Design Engineer for final design of approximately 5 miles of 36-inch
<br />cement mortar lined and coated (CML&C) steel potable water pipeline
<br />along Jamacha Road/SR-54 within the city of El Cajon and County of
<br />San Diego; and replacing approximately 3,500 LF of a 12-inch steel
<br />pipeline that is severely corroded. Project challenges include pipeline
<br />installation in heavily traveled roadways, including Caltrans SR-54;
<br />traversing environmentally sensitive habitats, including jurisdictional
<br />wetlands, Least Bell'sVireo and Southern Willow Flycatchers, California
<br />Gnatcatcher, and rare plant species; maintaining services to customers
<br />along portions of the 12-inch pipeline replacement; major RCB culvert
<br />crossings;15-foot deep microtunnel under a creek; and congested
<br />utility corridors. Multi -agency coordination included Caltrans District
<br />11, City of El Cajon, and County of San Diego. Private entity coordination
<br />includes Grossmont-Cuyamaca Community College District, Cuyamaca
<br />Water Conservation Garden, and various elementary school districts.
