I have 45 years of experience in water resources engineering and planning, including: surface and groundwater hydrology; hydraulics and water quality; surface and ground water modeling; groundwater management, including recharge master plans; water resources systems planning, operation, and optimization; water rights; evaluation of receiving water impacts; and flood control facility design. I have extensive expertise in the development of water resource management plans for groundwater basins and watersheds in California, and I have provided expert witness testimony and opinions for litigation support and mediation in several important cases—the most recent being the recalculation of the Chino Basin safe yield and Phase 3 trial in the Antelope Valley groundwater adjudication.I am an expert in the hydrology of the Santa Ana Watershed, having developed groundwater models at some time in his career for all the groundwater basins in the upper watershed and highly integrated surface and groundwater models for the Santa Ana River and its tributaries and underlying basins. These models are in active use to manage the Chino, Cucamonga, Six Basins, Temescal, and Mammoth Basins. Most notably, my team’s work forms the basis for the estimation of sustainable yield and the development of groundwater storage and recovery programs. I developed the recharge master plan concept, utilizing detailed surface water models and statistical techniques to identify new recharge projects and to determine expected new recharge and cost. In the early 2000’s, I designed and subsequently led the process to develop the salt and nutrient management plans for the Santa Ana River Watershed that was the forerunner of California’s SNMPs. My work has withstood peer review and has been relied on in court, adjudicated basins, regulatory processes, and project financing.I am married to my high school sweetheart, and we have raised four wonderful and intelligent kids. We recently relocated to Dana Point California to be near our kids and grandkids and where we plan to retire in a few years. My wife and I are co-owners with one our sons of Billy’s Delicatessen, Meat and Seafood in San Clemente California.
