DRC provided design services for the LADWP Silver Lake Headworks project. The project was placed on “hold” due to soils issues. After the “hold” was lifted, the LADWP took the project “in-house,” requesting contract assistance from DRC to provide an engineer in their offices to complete the project. DRC’s Fang Maw Lee, PhD, PE, was contracted to complete the design of the inlet pipelines, the outlet pipelines, the air vacuum vault, the under-slab drains, the rooftop drains, the discharge pipe to the adjacent river, drainage facilities, and other miscellaneous parts of the project.
During the preliminary design phase, Dr. Lee suggested eliminating the air vacuum vault and realigning several pipelines. Dr. Lee showed the LADWP that those facilities were unnecessary. The LADWP staff evaluated his recommendation and designs and accepted them.

“DRC more than justified their fee with the idea of removing from the design the ‘air gap’ vault. After a careful evaluation of his suggestion, we [concluded] that in fact the airgap vault was not needed. This design change, in my opinion, will save LADWP at least a couple of million dollars in construction and a few more million in operation costs during the life of the project.”

This project widened the Lower Mission Creek in the City of Santa Barbara from State Street, near the Santa Barbara pier, to Mason Street, a width of 35 feet to 55 feet. As prime consultant, DRC prepared the design, plans, and specifications for the construction of this first reach with USACE oversight and sponsored locally by the County of Santa Barbara. The project required significant environmental mitigation and constraints on surrounding habitat areas, fish habitat design, permitting, and the oversight of a biologist.
The American Public Works Association’s award cited DRC’s exceptional design and construction effort in which significant environmental compliance issues for endangered species and a wetlands area, within a limited work area adjacent to a hotel and restaurant, required unique construction methods. Fish ledges were designed and constructed within the creek for the goby fish species, a unique drilled pile system was designed and piles installed by the “flightauger” method to reduce noise, and an aesthetic shotcrete wall system was designed and integrated into the pile system. All designs and construction methods met the requirements of a City of Santa Barbara Blue Ribbon Committee.
Final design material consisted of HEC-RAS model hydraulic design confirmation, environmental design confirmation, unique pile/ wall design, levee design, channel design based on USACE criteria, structural calculations, contract drawings, specifications, MII (MCACES) quantity/cost estimate, DrChecks system project reviews, and Engineering Considerations and Instructions for Field Personnel. DRC resolved all outstanding design issues, including organizing meetings to discuss those issues and documented the agreed upon resolutions that represented a commitment from all parties to the recommended design. DRC prepared and furnished the construction cost estimate and bid schedule.

DRC designed and oversaw construction for the Los Angeles Department of Water and Power (LADWP) to construct an aesthetically pleasing, permanent man-made stream and water feature in Griffith Park. DRC produced a complete design engineering and construction package, including all required construction drawings, details, and equipment lists.
LADWP operates the Fern Dell Drive Facility water feature. The man-made water feature consists of a stream that is lined with cedars, pines, and other flora and fauna. Small waterfalls, pools, and bridges are incorporated into a popular picnic and walking destination for visitors to the historic park.
The Fern Dell Facility water supply is from a municipal water line. The water feature is designed to be a closed system, so that flow will be re-circulated indefinitely. Under the configuration, the stormwater outlet from the system is not available for routine flushing, but only during storm events that exceed the facility’s capacity. The existing storm water bypass channel is being maintained. The system required a pumping station and associated piping network to continuously re-circulate water through the existing creek. The pipeline extends from the pump station at the creek’s downstream to a pond above a playground at the upper end of the facility.
The Fern Dell system has a series of weirs that facilitate the approximate 190- foot elevation drop from top to bottom, which includes a waterfall feature. These features generate enough aeration to prevent dissolved oxygen concentrations. No forms of water treatment in the system existed, but examining the parameters of concern and assessing the available technology to facilitate the requirements of a safe, aesthetically pleasing water feature became necessary.

The City of La Mirada contracted with the U.S. Army Corps of Engineers under a prime contract with DRC to perform a feasibility- level design document that includes the hydraulic grade line and project design plates for proposed storm drainage improvements at ten sites. The project plans include information of the existing drainage facility and how it is being modified to remediate the local flooding at those sites. The feasibility-level design plates include standard drawings from the Los Angeles County “Green Book.” In addition to the feasibilitylevel design, the final document also includes a feasibility level, project quantity take-off and site-specific project cost for each site.
As prime consultant, DRC reviewed the city’s Storm Water Flooding study (March 2008), including the feasibility-level hydrology and hydraulic technical planning appendix, to determine the unmet 25-year project discharge magnitude for all ten project sites. Based on field conditions, we determined the viability of designing a conceptual 25-year flood control storm drain plan. The determining factor is analyzing the capacity of the receiving disposal point based on the watershed evaluation of the drainage facilities. We reviewed the existing utility pipeline profiles to determine a practical bypass for the feasibility-level, storm drainage system at each of the 10 sites. DRC performed a feasibility-level hydraulics grade analysis to demonstrate that the downstream end of the project can receive the additional flow moving through the proposed storm drains to the terminus point.
DRC provided feasibility-level design data for the storm drainage pipes to help reduce the local flooding at the ten flooding sites. The feasibility-level design includes a conceptual plan and profile plates with starting and ending profile data and, as much as possible, the location of other utilities in the vicinity of the proposed project pipeline, for each site. We determined if there was an innovative solution that could be constructed under the constraints of the existing flow gradient or real estate limitations and provided a conceptual solution for any of the ten sites to help solve the flooding conditions, at a feasibility-level detail, at all of the sites.

The U.S. Army Corps of Engineers Geotechnical Branch evaluated alternative approaches and associated costs for railroad embankment under-crossings integral to this flood control project. D R Consultants & Designers (DRC) performed a geotechnical assessment, including drilling, logging, sampling, and permitting to facilitate the evaluations and cost determinations.
As Prime Consultant, DRC provided traffic control and underground utility clearances; coordinated and provided all necessary city/state/railroad permits, including right-of-entry on Burlington Northern and Santa Fe Railway Company (BNSF) land. We ensured compliance with all applicable regulations with the Department of Water Resources and Burlington Northern and Santa Fe Railway Company requirements, including obtaining specialized insurance and permits to ingress and work on railroad land.
DRC conducted the subsurface utility avoidance verification effort, prepared a project-specific Safety and Health Plan, which focused on drill rig stability and worker safety on slopes, in forested areas, around overhead wires, near active railroad tracks, and within 25 feet of the centerline of railroad tracks. We prepared Traffic Control Plans, which took under consideration the use of the adjacent Chamber of Commerce parking lot as the ingress-egress point. Maintaining access and a good relationship with the Chamber was critical in our traffic plans since using other alternatives in the area would be more costly and cause more difficult traffic control issues.
DRC earned an “Outstanding Performance Rating” for this project.

DRC modified the original services for installing four new test wells for the Eastern Municipal Water District (EMWD) Property or Easement in the Perris Basin Desalination Program, a city in Riverside County, CA.
The project required an analysis of formation samples, a sieve analysis of drill cuttings, and an analysis of downhole geophysical logs after drilling commenced. They determined the depth of each well. The final well designs and decision to complete each test well were contingent upon the results of these analyses.
The work included reaming, installing blank and louvered well castings, installing gravel pack, and well development. DRC monitored the project, created the work plan, and a project schedule. We completed the welding of the steel plate over the top of the well casing, tubing, and annular space between the well and conductor casings to protect the wells from vandalism per the approval of the EMWD.
Our personnel conducted field investigations, installed and developed two new test wells located in city of Perris, Riverside County, California, in accordance with the technical requirements. The work included drilling, downhole geophysical and caliper logs, well construction, development, testing, alignment surveys, color video, disinfection, and pump foundation.
We submitted test well documents and data. The new test wells were drilled and completed so as to produce from all water-bearing zones of acceptable properties and of water quality identified by the EMWD. If waterbearing zones were not considered adequate to produce the desired quantity and quality of water, the pilot borehole was destroyed and site work terminated. The operational capacity of the new test wells ranges from 300 to 1,000 gallons per minute (gpm).

DRC reviewed the hydrologic and hydraulic modeling performed under future climate change scenarios and identified specific scenarios to consider for adaptation planning. The project goal was to develop conceptual-level information, including costs for conveyance to the site from the aqueduct.
We identified two locations along the Los Angeles Aqueduct for potential aquifer storage and recovery sites to provide 400,000 acre-ft of underground water storage, developed above ground infrastructure requirements for transport, temporary storage, and recovering water for those sites within ten miles of the aqueduct. Our team worked from USGS and other topographic-style maps.
DRC provided conceptual designs and cost estimates for the required aboveground infrastructure and identified opportunities to enhance conveyance capacity of the aqueduct immediately downstream of Haiwee Reservoir, including developing conceptual designs and cost estimates.

This reservoir is formed by two earth/rock fill dams about 4.4 miles apart within the Domenigoni and Diamond Valleys. The reservoir receives water from the State Water Project (SWP) and from the Colorado River Aqueduct (CRA). The San Diego Canal (SDC) and a new 12-foot- diameter pipeline within the SDC right-of-way supply water to the reservoir from the SWP and the CRA.
DRC staff produced various analyses, using an integrated resources management approach, which included, containment and control plans and collection and distribution systems modeling. The project involved relocating seven miles of Newport Road, which formerly ran through the valley; 1.5 miles of the SDC; utilities; and designing a 54-inch diameter treated effluent pipeline, approximately 11,000 lineal feet long. The Diamond Valley Lake Project involved the design and construction of the following:
• An earthfill/rockfill embankment on the west end of the reservoir, 1.8 miles long and 280 feet high, which required 54 million cubic yards of fill, and incorporated a central clay core with rock shell, a bentonite slurry-wall cutoff and drains, which required a 60-foot excavation to a hard alluvial foundation;
• An earthfill/rockfill embankment on the east end of the reservoir, 2.2 miles long and 180 feet high, which required 330 million cubic yards of fill, and also incorporates a central clay core with rock shell, a bentonite slurrywall cutoff and drains, which required a 90-foot excavation to bedrock;
• A large roller-compacted concrete saddle dam along a low point in the hill that forms the northern boundary of the site and a saddle dam, which required one million cubic yards of fill;
• A pump generator (P/G-1) and fore bay at the north abutment of the west dam and substation; a generating plant at the head of the San Diego Canal; a substation; an inlet/ outlet structure and tunnel. Maximum inflow will be 2100 cubic feet per second (cfs) maximum outflow, 2200 cfs.
