Travis Whitted has managed and performed geotechnical studies for a wide variety of projects including wineries, public capital improvements, wastewater treatment facilities, pipelines, schools, fire stations, low and high density residential structures, recreational facilities, bridges, and commercial and industrial improvements. Using high end computer software to analyze the stability of slopes is one of his specialties. Applications include reservoir embankments subject to rapid drawdown, ancient landslides that may be subject to reactivation, and designing repair options for recent landslides and other slope related failures. He has provided forensic analysis for structural failures and foundation stresses due to soil settlement, expansive soils, unstable slopes, and moisture intrusion in addition to roadway and pavement issues including inadequate subgrade support, utility trench settlement, and piping failures. Mr. Whitted has extensive experience with grading projects ranging from hillside cuts and fills with keyways and subdrains to roadways and reservoirs. He has geotechnical engineering experience in Mendocino, Sonoma, Napa, Lake, Marin, and Monterey Counties.
He enjoys spending time with his wife and three kids and if he can find spare time he likes hacking around the golf course and restoring and racing old cars. And if it requires buying a new tool, he will gladly take on a new project around the house!
