Smith filed at the County Courthouse at about 3 p.m. on Tuesday, having announced her intentions earlier in the day at the Republican Women of Summit County's monthly luncheon.
"She got a minute or so of a standing ovation," Summit County Republican Chair Henry Glasheen said. "She seems like she's going to get a lot of help and do well with fundraising."
He noted that because she has already saved taxpayers $1.8 million through the tax petitions she successfully circulated and filed Monday, she goes into the race with solid credentials.
Smith said that when she heard Duane Schmidt was stepping out of the race, leaving Democrat Kim Carson unopposed, she wanted the county to have a choice.
"While my opponent is a very nice woman, she has been on the Park City School Board for the last eight years, and during that time, there has been a $2 million deficit, I think just in the past year," Smith said.
Smith said the county needs someone who will be fiscally conservative with the county's money.
"In this year alone, me and a few other citizens have saved the North Summit residents $8.5 million, and with this petition drive we've saved another $1.2 million," Smith said. "I have a very strong business background and I believe we can do this without people losing their jobs.
Because Smith is a write-in candidate, her name will not appear on the ballot, nor will she be affiliated with a party. Voters will need to specifically write her name in the provided write-in candidate space on the County Council Seat C section of the ballot.
