Ali Bastani, PhD, slopes, and overall grading logistic study for the proposed 5,000-acre-feet PE, GE, F. ASC E recycled water reservoir which will replace the existing dam. (Continued) Trampas Canyon Dam and Reservoir, Santa Margarita Water District - Orange County, CA: Geotechnical Quality Assurance during construction of the 5,000-acre-feet recycled water reservoir that included construction of three earth fill embankment dams, a spillway, inlet/outlet works, pump station, and other appurtenant structures. Santa Ana Delhi Channel, Orange County Public Works - Newport Beach, CA: Project Manager in charge of providing geotechnical design recommendations for 35% design for the proposed channel modifications downstream of Mesa Drive (STA 39+90) to Upper Newport Bay (STA 5+52) in the City of Newport Beach, California. Our investigations included 12 cone penetration tests and review of available geotechnical borings. The analyses included sheet pile wall design recommendations for increasing the channel capacity and mitigating the channel banks erosion and providing geotechnical recommendations in support of a Type Selection Report for the proposed pedestrian bridge replacements. Greenville -Banning Channel (1303) Rehabilitation, Orange County Public Works - Santa Ana, CA: Project Manager in charge of providing geotechnical design recommendations for channel slope repairs from Centennial Road to West Segerstrom Avenue in Santa Ana. Our investigations included ten hollow - stem -auger borings and vertical and horizontal hand auger borings at seven locations to evaluate the existing slope conditions. A reinforced earth option was evaluated for stabilizing the channel slopes against erosion. Fullerton Creek Channel Improvement, Orange County Public Works - Buena Park, CA: Project Manager in charge of providing geotechnical design recommendations for groundwater monitoring and design recommendations for the proposed channel modifications between Western Avenue (STA 105+80) and Dale Street (STA 167+00). Our investigations included four groundwater monitoring wells, seven dynamic cone penetration tests, eight borings, and fifteen cone penetration tests. Our field investigations were coordinated with the City of Buena Park, County of Orange, and property owners adjacent the channel. The analyses included soil nail wall designs for three overcrossings and finite difference numerical modeling for evaluation of the construction induced deformations during shoring installation, excavation, installation of the concrete channel, and release of restrains. Gobernadora Multi Purpose Basin, Santa Margarita Water District - Orange County, CA: Geotechnical Engineer of Record during design and construction of 130 acre-feet basin south of Coto de Caza. This basin collects, purifies, and percolates niceness water from Coto de Caza run offs, which is pumped to a recycled water reservoir for reuse.
