Derrill G. Whitten, Jr., PE, LS

Derrill Whitten began his engineering career initially in the oil industry. He attended the University of Texas at Austin and graduated with a Bachelor’s Degree in Petroleum Engineering in 1985. In 1990, Derrill left the oil business and took a position as a draftsman with Cornerstone Engineering. By 1993, he had obtained his Civil Engineering License and was managing a variety of civil engineering work in Kern County. Projects of note included: Flying J Travel Center in Lebec, California; Green Waste Facility for the City of Bakersfield; and Spill Prevention and Countermeasure Plans for Chevron Pipeline facilities throughout the state of California.

In 1995, Derrill left Cornerstone to further broaden his engineering experience with Roberts/Schornick and Associates of Norman Okla. RSA became a part of the Benham Group of Oklahoma City, and was a leading environmental consulting firm in the Midwest. As a Senior Civil Engineer, he prepared and implemented major RCRA cleanup projects in Kansas and Oklahoma. Derrill’s last three years with RSA were spent on a $25,000,000 smelter site cleanup for the Zinc Corporation of America. The site, in Bartlesville Oklahoma, was contaminated with nearly a centuries worth of smelter residue. He was responsible for the closure design documents as well as the construction inspection during implementation. While in Oklahoma, Derrill obtained his license as a professional land surveyor.

In 2000, Derrill moved back to Bakersfield, California to take a position with the City of Bakersfield. This provided invaluable experience with the inner workings of city government. He served from 2000 to 2002 as a Civil Engineer in the Capital Projects Group. From 2002-2005, Derrill served as the City of Bakersfield Wastewater Manager. As Wastewater Manager, Derrill managed the day to day operations of the Wastewater Division of Public Works, including staffing, long-term capital planning, annual budgeting, permitting, and regulatory compliance. He acted as representative for the City of Bakersfield in matters pertaining to wastewater and water issues. Derrill also presided over several plant upgrade projects and the initial planning for the expansion of Treatment Plant 3 during his tenure and was licensed as Grade Five Waste Water Treatment Plant Operator. After 5 years, in October of 2005, Derrill left the City of Bakersfield to rejoin the staff at Cornerstone Engineering.

Derrill has been married to his wife, Barri, for over 30 years and they have three sons. Derrill enjoys biking, racquetball, competitive sailing and playing bass and acoustic guitar for his church worship services.
