City of Riverbank

Riverbank City Council, District 3

This person would represent one of Riverbank's four City Council districts. They would vote on city laws, the budget, and land use. Riverbank is a Stanislaus County city of about 24,865 residents. Riverbank uses a council-manager government. A professional City Manager runs day-to-day operations. The elected council sets policy. The Mayor is elected at-large, citywide, and is not on this ballot. Rachel Hernandez has held the Mayor's office since her 2024 election. The four council seats are elected by district to staggered 4-year terms. Districts 1 and 3 are up this November.

Two candidates are running for Riverbank's open District 3 council seat. They are Carissa Commons and Sammi Martinez. Whoever gets the most votes on November 3 wins. There is no runoff.

This seat is one of Riverbank's four district-elected City Council seats, alongside a citywide-elected Mayor. Councilmembers vote on the city's budget, ordinances, and land use; day-to-day operations run through a professional City Manager. Riverbank's council seats serve staggered 4-year terms -- Districts 2 and 4, and the Mayor, aren't up again until their own terms expire.

The seat is open because District 3's sitting officeholder, John Pimentel, currently holds it by prior Council appointment rather than election -- the city's own filing record labels him "Appointed Incumbent" -- and he is not seeking election to it this cycle, which is why neither candidate below carries an incumbent marker. A third person, Alex Rodriguez, pulled nomination papers for this seat but never filed them.

Carissa Commons

Carissa Commons is running for Riverbank's open District 3 council seat. Their ballot designation is "Hospice Nurse/Mother." They were the first to pull nomination papers, on July 13, 2026. They filed them July 29 and were verified August 3, 2026. No campaign committee, news profile, or website was found for them.

Sammi Martinez

Sammi Martinez is running for the same seat. Their ballot designation is "Fraud Investigation Technician." They pulled nomination papers on July 20, 2026. They filed them August 5, 2026 and were verified the same day. No campaign committee, news profile, or website was found for them.
