Veteran County Commissioner Becky Heron plans to resign her seat, a year and a half before her term expires.
"I think it's time," said Heron (right), who has served on the county board since 1982. "That's a lot of years."
Heron, 83, said she has had "a few minor medical problems" that led to her decision to step down.
She did not say when she plans to actually leave office, and said she will recommend a successor to her board colleagues. It will be up to the commissioners to select a member to serve out Heron's term, which ends in December 2012.
"It's been a good run for me," she said, "and I wouldn't take anything for those years on the county commissioners. It's been a great experience.
"I can't speak for my husband on that."
Heron is married to retired Duke University geology professor Duncan Heron.
