Contra Costa Elections Deploys 1,200 Workers Across 150 Poll Sites

Inside the Contra Costa County Elections Division headquarters in Martinez, Clerk-Recorder-Registrar Kristin Connelly and more than 1,200 permanent staff, temporary workers, and community volunteers completed final preparations on Monday for Tuesday's Nov. 3 general election, according to Richmond Confidential.

150 Polling Places, 43 Drop Boxes, and 44 Poll Worker Training Sessions

To manage countywide voting from Walnut Creek and Concord to Richmond and San Ramon, the Elections Division scaled its seasonal workforce over the past month:

• Workforce & Training: Approximately 100 temporary workers—including 24-year retired county veteran Rose Mena, who returned after retiring 6 years ago to supervise envelope sorting—work alongside roughly 1,100 Election Day staff and volunteers who completed 44 training classes over 2.5 weeks.
• Polling Hours & Projected 50% Walk-In Surge: All 150 Contra Costa polling places will open from 7 a.m. to 8 p.m. on Tuesday, Nov. 3, complementing 43 secure ballot drop boxes positioned across the county. County election officials are preparing for a projected 50% surge in in-person Election Day voting compared with recent cycles, with Martinez ballot-processing teams scheduled to work until 3 a.m. Wednesday morning.

38,000-Envelope-Per-Hour Sorting and Three-Level Signature Verification

Every vote-by-mail envelope returned via the U.S. Postal Service or one of the county's 43 drop boxes passes through a multi-stage chain of custody inside the Martinez facility, where public observation windows and live video feeds allow residents to watch each step:

• High-Speed Imaging & 3 Verification Tiers: An industrial sorting machine capable of processing up to 38,000 envelopes per hour captures a digital image of each voter's signature and compares it against the voter registration file. Questioned signatures undergo up to 3 levels of human review by trained staff before an envelope is cleared or flagged for voter curing.
• 2-Person Extraction & Air-Gapped Tabulation: Once verified, 2-person teams open the envelopes and flatten the ballots—separating the signed envelope from the ballot to preserve voter secrecy—before feeding sheets into air-gapped tabulation scanners that are never connected to the internet. Under California law, mail ballots postmarked on or before Election Day will continue to be accepted for 7 days after Tuesday's vote.
