Project Experience
Dee Jaspar has been involved in civil engineering projects for the past thirty-six years. He has experience in design of small dams (including retrofitting existing dams), canals, pipelines, municipal and agricultural wells, pumping plants, water treatment plants, and surge control equipment. He has prepared grading plans, drainage plans, site development plans, tract maps, parcel maps, drainage studies, land use plans (including specific plans), tract improvement plans, and ALTA surveys. He has surveyed municipal, urban, agricultural, and mountain properties, performed construction staking, and participated in aerial-topographic surveys. Mr. Jaspar has designed and constructed commercial and industrial buildings. His structural experience also includes retaining walls, foundations, small bridges, crane buildings, and water storage tanks. He has performed ground water studies, shallow ("perched") water studies, and ground water pollution studies for agricultural evaporation basins, and deals with the State Regional Water Quality Control Board in these matters. He participated in a joint Bureau of Reclamation/Department of Water Resources study of the soils and ground water underlying an agricultural evaporation basin in southern Kern County, conducted studies of the contaminants in the liners of agricultural evaporation basins in northern Kern County, and has prepared closure plans for said basins. He has performed energy use studies for water pumping plants and other water-related facilities. Mr. Jaspar co-chaired a Technical Advisory Committee for a California Energy Commission study (1977) on the use of a power for pumping irrigation water. He co-authored a paper for the American Society of Civil Engineers on the control of transient pressures in pipelines (Pittsburgh, Pa., 1978), and a paper for the Eleventh Ozone World Congress regarding the use of ozone treatment of municipal water systems (San Francisco, Ca., 1993). Mr. Jaspar performs forensic engineering and expert witness work in the western United States. He has delivered expert witness testimony as a technical expert in underground pipe installation, land surveying, and flood damage cases.
