Millcreek residents in District 1 have until Wednesday, Nov. 18, to apply for the City Council seat Silvia Catten is leaving behind.

Catten, a founding member of the Millcreek City Council, won the Utah Senate District 13 race with 77.71% of the vote, as first reported by ABC4. Republican Ryan Mahoney received 18.79%, and Forward Party candidate Colin Smith earned 3.5%. While election results are not yet official, the margin is decisive. Catten will replace Sen. Nate Blouin in the seat.

Her departure opens a mid-term vacancy on the founding council formed when Millcreek incorporated.

The city began accepting applications on Wednesday, Nov. 4, according to the city's elections page. All applications must be delivered in person to the Recorder's Office at Millcreek City Hall, 1330 E. Chambers Ave., during regular business hours, 8 a.m. to 5 p.m., by Nov. 18.

The council will interview candidates and select the new District 1 representative at a public meeting on Monday, Nov. 23, no earlier than 4 p.m. at City Hall. The appointed member will serve from Jan. 1, 2027, until a new council member is sworn in after the November 2027 municipal election.

Who can apply

Applicants must be a U.S. citizen, a registered Millcreek voter, a resident of City Council District 1 and must have lived in Millcreek for at least 12 consecutive months before Nov. 23, 2026. The application packet includes a Declaration of Candidacy form, a resume of no more than two pages, a one-page letter of intent, a questionnaire, a conflict of interest form and a $50 filing fee.

District boundaries are available on the city's website.

Catten's decade on the council

Catten served 10 years as the District 1 representative, according to the Millcreek Journal. She got her start on a community council that operated through Salt Lake County before Millcreek incorporated as a city.

In coverage published in July 2026, Catten told the Millcreek Journal, "I saw something in a newspaper about joining, and I was the youngest by far, I was 23, but I just kept showing up."

Mayor Cheri Jackson said, "Silvia has been such an important part of Millcreek's story from the very beginning," according to ABC4. Jackson praised Catten's dedication to the city and said Utah is gaining a strong leader.

Catten called serving Millcreek "one of the greatest honors" of her life, ABC4 reported.

The District 1 seat will be on the ballot again in the November 2027 municipal election.
