Douglas County Commissioner Steve Weissinger is resigning from the board as of the end of the year after serving a jail term for stealing from his employer.
He said his decision was related to his misdemeanor embezzlement conviction in California's El Dorado County, which put him in jail for eight days last month.
Weissinger, who is in his second term, said he decided to leave the five-member board so it could go into next year without a cloud over its head.
Commissioner Bernie Curtis told the Reno Gazette-Journal the other board members had encouraged Weissinger to resign.
"I think that Steve has done what is right," Curtis said. "I hope he can get his life together and move on."
Weissinger declined to discuss the details that led to his arrest in June after he was accused of taking money from the Raley's supermarket in South Lake Tahoe where he worked for 14 years as a manager.
He maintained he accidentally pocketed a $100 bill, but the judge ordered him to pay $1,315 in restitution.
"I don't want to reopen what happened at Raley's," he said. "I wish that it had gone a different way. I can't change it. The case is closed. I don't want to get caught up in all the ins and outs."
He pleaded no contest to two embezzlement charges and served eight days of a 10-day jail sentence. He also was placed on three years' probation.
In a letter he intends to submit Thursday, Weissinger said he resigns with a "heavy heart and sincere apology" to his family, fellow commissioners, county staff, elected officials and residents of Douglas County.
"To say it has been a difficult time the past five months for me personally would be an understatement," Weissinger said in his letter. "I fully accept responsibility for my actions, faults as a man and human being."
He said he hopes he will be remembered as a hardworking commissioner.
