The Mohave County supervisors Monday promoted Mike Hendrix from assistant public works director to public works director effective immediately.
Hendrix, who started in 1985, replaces Dick Skalicky, who will retire in December from a job he has held since 1988.
Hendrix said his salary will increase from $74,000 to $87,000 a year.
Hendrix will assume the duties of county engineer, flood plain administrator, flood control district manager and superintendent of streets for all county improvement districts, according to the motion approved by the supervisors.
Hendrix will be responsible for about 200 employees.
Hendrix, 44, said he was honored to be promoted.
During his tenure, the department has paved 30 miles of roads in Butler and 15 miles in Golden Valley, he added.
"It has not been me who has done this," Hendrix said.
"It has been a team effort."
Hendrix also praised Skalicky.
"I've learned a lot from him," Hendrix said.
"Without Dick, we probably would not have any improvement districts in the county."
Skalicky, 62, said he may do consulting work after retiring.
He also was acting county manager during a transition before Paul McIntosh was hired in 1997 and after McIntosh left in 2000 and before Ron Walker came on board in 2001.
Walker urged the supervisors to promote Hendrix instead of trying to recruit Skalicky's replacement.
The supervisors agreed with Walker.
"I believe Mike Hendrix is extremely qualified," District 2 Supervisor Tom Sockwell of Bullhead City said.
"He is always responsive."
Hendrix, a native of Joplin, Mo., graduated from Kingman High School in 1976 and earned a bachelor's degree in engineering from the University of Arizona.
He holds professional registration as a civil engineer.
During his spare time, Hendrix said, he goes hunting and fishing and plays the guitar.
He lives in Kingman with his wife, Cherie, and son, Joshua.
