Humboldt County Fourth District Supervisor Natalie Arroyo Running Unopposed After Filing Deadline

Eureka Fourth District Supervisor Natalie Arroyo announced March 6 that she has learned she will run unopposed for re-election after the county’s candidate filing period closed, leaving voters in Eureka, Myrtletown, Fairhaven and Samoa without a contested primary ahead of the June 2, 2026 election. As things currently stand, incumbent Fourth District Supervisor Natalie Arroyo is running unopposed as she seeks a second four-year term on the board, and the filing window closed at 5 p.m. on Friday.

Arroyo formally launched her re-election bid on November 8, 2025 at Madaket Plaza in Eureka overlooking Humboldt Bay, telling supporters, "Simply put, I love Humboldt County and am honored to serve as your representative in District 4. These are challenging and dynamic times, and I bring experience, relationships, and knowledge you can count on. Thank you for the opportunity and I hope to earn your vote for a second term!" Peninsula Community Services District Board President Leroy Zerlang and Humboldt Bay Municipal Water District board member Sheri Woo delivered remarks at the announcement, and campaign photography was credited to Arne Jacobsen.

A longtime Eureka resident, Arroyo was elected to the Fourth District seat in 2022 and is noted as the first Latina to serve on the Humboldt County Board of Supervisors. Her campaign biography lists prior service on Eureka City Council representing the 5th ward from 2014 to 2018 and the 3rd ward from 2018 to 2022, and describes her professional roles as a watershed restoration specialist, trail planner, college educator, and a proud veteran. Arroyo’s campaign said she has been endorsed by Congressman Jared Huffman, State Senator Mike McGuire and Assemblymember Chris Rogers.

Election-night tallies from Arroyo’s earlier contest to replace Virginia Bass showed a narrow path to an outright win: with 2,036 votes counted she held 52 percent to opponents’ 32 percent and 15 percent; with 2,169 votes counted she had 51 percent to 33 percent and 15 percent; and a later tally with 2,354 ballots recorded Arroyo at 50.21 percent while Mike Newman and Kim Bergel trailed at roughly 34.71 percent and 15.08 percent, leaving her described as "clinging delicately to the 50-percent threshold needed to avoid a November runoff."

The filing-period developments also left the Fifth District race in a similar state, with Mary Burke listed as a hopeful and that seat described as running unopposed as the filing deadline approached. With the primary election scheduled for June 2, 2026, Arroyo moves into the spring campaign season seeking a second four-year term without a ballot challenger after the Friday 5 p.m. filing deadline closed.
