Four candidates for the Palo Alto City Council picked up the official filing papers Monday and new candidate Debbie Mytels joined the race.
Victor Frost, who picked up papers, had also not previously announced his candidacy, although he has run in the past.
Mytels is an associate director of the environmental non-profit Acterra and she co-founded the Midtown Residents Association.
"I think there's some interesting opportunities for us to work on the climate change and energy initiates," Mytels said, noting she was also interested in involving more citizens in community affairs.
Mytels, who had previously said she wasn't planning to run, was encouraged to join the race by political insiders.
Frost is a homeless advocate who spends his days panhandling across the street from Whole Foods Market on Homer Avneue in Palo Alto. He has run for council at least four times.
Sid Espinosa, Pat Burt and Dan Dykwel also picked up their packets Monday, according to City Clerk staff member Tabatha Boatwright. Espinosa had said he was going to try to return the papers by 5:30 p.m. Monday.
Four seats on the nine-member council will be open.
Candidates must gather at least 25 signatures of registered voters. With 100 signatures, a candidate does not have to pay the $25 filing fee, according to City Clerk Donna Rogers. The papers are due Aug. 10. The election is Tuesday, Nov. 6.
