The projects included flood <br />control, water quality, and wildlife corridor or habitat conservation and protection. Michael Baker <br />also provided services to obtain resource agency permits. <br />Highland Booster Station Upgrade, Yorba Linda, California. Yorba Linda Water District. <br />Structural Engineer for several foundation structures required for the proposed upgrade. <br />Michael Baker provided engineering design and construction management and inspection <br />services for upgrades to the Highland Booster Station. The pump station was increased to a <br />total capacity of 15,000 gallons per minute, and the project included modification of two of the <br />four electric driven motors and pumps. The project also included the addition of a natural gas- <br />driven backup generator and potential for increasing the pumping capacity of the two remaining <br />electrical driven pumps by 2,000 gallons per minute in the future.( <br />Soquel Canyon Pump Station No. 1, Chino Hills, California. City of Chino Hills. Structural <br />Engineer. Provided structural design for an 80-foot by 25-foot CMU building to house the pump <br />station. Michael Baker prepared environmental documentation, preliminary design report, <br />plans, specifications, and cost estimates for a dual-owner facility consisting of two new booster <br />pump stations housed in a single building, one for domestic water and the other for recycled <br />water. The domestic water booster pump station was designed to boost water from the City of <br />Chino Hills' low zone to its Intermediate zone. Due to the site's close proximity to surrounding <br />homes, equestrian riding area, and SCE transformer towers, extensive site work for the project <br />was required and included the design of a 16-foot-high retaining wall around the majority of the <br />site in order to accommodate the building footprint and site access requirements. Other project <br />features included design of a stand-by emergency generator, extensive landscaping, <br />reconstruction of a horse trail, specialty electronic gates, and a security system. <br />Advanced Water Treatment Facilities for the Groundwater Replenishment System, <br />Orange County, California. Structural Engineer. Michael Baker in a subconsultant role, <br />provided engineering services for a Microfiltration Break Tank, Reverse Osmosis Transfer Pump <br />Station, Air Gap Pump Station, and Research Center for the Groundwater Replenishment <br />System. Jointly sponsored by the Orange County Water District (OCWD) and Orange County <br />Sanitation District (OCSD), the groundwater replenishment system will provide a new, reliable, <br />high-quality source of water to recharge the Orange County Groundwater Basin, protect the <br />basin from seawater intrusion and, by recycling water, postpone the need for OCSD to construct <br />a new ocean outfall. The Microfiltration Break Tank Is a 165-foot by 95-foot by 27-foot-deep <br />subterranean concrete water storage reservoir supported on pile foundation. The roof slab <br />supports 14 vertical turbine pumps, an 84-inch diameter steel piping system, and the Reverse <br />Osmosis Transportation Pump Station building. The Reverse Osmosis Transfer Pump Station is <br />a 165-foot by 32-foot by 23-foot steel-framed building with a steel moment frame and braced <br />frames. The Air Gap Pump Station is a single-story steel pump station with an 18-inch-diameter <br />by 32-foot-high steel tank on a pile-supported concrete slab foundation. The Research Center is <br />a single-story steel-framed roof system over the 165-foot by 50-foot outdoor research area. <br />IRTLCNII,ob.AL Fablo Sanchez -Duran, P.E., S.E., SECB <br />25B-64 <br />
