Shaw, who ran with Boardman as part of Team Huntington Beach, spent years as a planning and public works commissioner.
Harper had never run for the council before, but has 12 years of experience as a trustee for the Huntington Beach Union High School District Board of Education.
Even the candidates in fifth and sixth, Barbara Delgleize and Blair Farley, serve on the Planning Commission.
Official totals are pending as the Orange County Registrar of Voters counts provisional ballots. As of Wednesday morning, Shaw led Delgleize by 332 votes.
According to Boardman, the top vote-getter, voters may have sought experienced leaders during a tough time in Huntington Beach.
"It might be because of the fiscal problems and the budget crisis that people were favoring people who had experience, either on the Planning Commission or past experience on the council," she said. "I think a lot of us [candidates] made a point of that."
The last time Surf City had four open seats, in 2006, seven people ran for the council. This year, more hopefuls entered the race than in any other in the past decade and any other in Orange County this year, where the next largest was Anaheim, with 14 candidates vying for council and three for mayor.
It was an eclectic group of candidates, and some used unorthodox methods of campaigning. Andrissa Dominguez, a playground supervisor at Smith Elementary School, painted dried palm fronds to use as signs.
Landon Fichtner, a teacher in the Los Angeles Unified School District, spread the word about his candidacy by striking up conversations with people renting DVDs. The ballot even included Shawn Roselius, an 18-year-old who recently graduated from Edison High School.
