Dee Jaspar & Associates, Inc., founded in 1980 and established as a California corporation
in 1982, is a professional civil engineering corporation. For more than twenty five
years, civil engineers at Dee Jaspar & Associates, Inc. have specialized in project
management, design, and construction administration for both public and private
sectors. Dee Jaspar & Associates, Inc. is headquartered in Bakersfield, CA, with
a regional office in Porterville, CA.
Along with general engineering work, Dee Jaspar and Associates, Inc. performs water
system related work for municipal and agricultural clients in the Kern County and
Tulare County areas. Included in this category of work are: the design of water
wells, pipelines, pumping plants, storage tanks, and water treatment facilities,
feasibility studies, planning studies, rate structure development, water quality
studies, system hydraulics, preparation of water system standards for design and
construction, easement descriptions, construction staking, construction inspection,
and plan checking for water systems.

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.

Summary of Experience
Mr. Skaggs offers approximately ten years experience as a civil engineer. His experience
includes civil design, construction inspection, and management of civil engineering
projects for municipal water projects and agricultural water projects. During his
career, Mr. Skaggs has developed close working relationships with clients and local
agencies to present and complete engineering designs that meet the needs of our
clients. He performs the design and specifications for grading plans, water storage
tanks, pumping plants, water wells, sewer and storm drain systems, canals, weir
structures, pipelines, and well head treatment processes. He performs water distribution
system flow modeling, flood modeling, water system plan checking, and other engineering
services. His experience includes the preparation of water supply permit applications,
compliance with the drinking water source assessment program, and other permitting
