Duane T. Hartman
Oct. 20, 1933 – Sept. 7, 2020
Duane Thomas Hartman, PLS, a Washington State licensed Professional Land Surveyor #9158, passed away peacefully in his home September 7th at age 86 after a courageous battle with Parkinson’s disease. He was blessed to be surrounded by his family in his final days. Duane began his surveying career in 1951 with Seattle City Light on the Ross Hydroelectric Dam. After serving honorably in the US Army he studied Civil Engineering (1951-1955) and Photogrammetry (1957-1958) at the University of Washington. He joined Horton Dennis and Associates (HDA) in 1957 as a survey party chief. After becoming professionally licensed in 1965, he formed Hartman-West and Associates and later joined Jones and Associates in Bellevue, Washington in 1968, serving as their Vice-President from 1970 to 1971. He returned to Horton Dennis and Associates and became their Vice-President and Director of Surveying and Mapping in 1973. Over the next 17 years he built HDA into one of the largest and most notable survey firms in the Pacific Northwest, with up to a dozen licensed land surveyors and up to 17 survey field crews. He became a partner and Vice-President at Permit Engineering in 1989 and in 1993 purchased their assets to start Duane Hartman & Associates in Woodinville, Washington, now managed by his son, Doug Hartman. Duane was highly regarded by his peers’ and his legacy as the principal surveyor for the Trident Naval Base at Bangor, NAS Whidbey Island, the US Army Corps of Engineers, the Sound Transit Light Rail system and over a thousand Boeing projects is unmatched. He is fondly remembered as a congenial and kindly individual who encouraged and mentored countless now-licensed land surveyors’ throughout the Pacific Northwest. Memorial services, if any, will be announced at a later date.
