Former longtime Concord City Councilman and Mayor Dan Helix is being remembered by local elected officials following his death Wednesday at the age of 91.

U.S. Rep. Mark DeSaulnier, D-Walnut Creek, himself a former Concord councilman, noted that Helix was first elected to the Concord City Council in 1968 and served for eight years before also serving on the BART Board of Directors. He returned to the City Council as an appointee in 2010 and won election again in 2012.

Among his notable achievements, Helix was instrumental in bringing the Concord Pavilion to town as part of a housing development negotiation in the early 1970s. He also is credited with helping to preserve the Lime Ridge Open Space, according to a news release on the Concord city website.

Helix, a Korean War veteran and retired U.S. Army major general, served for 41 years in active and reserve duty and is a member of the U.S. Army’s Infantry Hall of Fame, according to DeSaulnier’s office.

“Dan Helix dedicated his life to serving his country and his community,” DeSaulnier said. “As a member of the United States Army and in his role as a councilmember and mayor of Concord, putting others first was Dan’s passion.”

State Assemblyman Tim Grayson, D-Concord, another former Concord councilman, said on Twitter that Helix “was a hero, lifelong public servant, author, valued community member, and beloved husband, father and grandfather to his family.”

Grayson said, “I was lucky to have known him as a friend and mentor. My condolences go out to the Helix family and all of his loved ones.”

State Sen. Steve Glazer, D-Orinda, also mourned Helix’s death, saying on Twitter that he “was short on words but long on wisdom. He was a special friend and will be dearly missed.”

City flags have been lowered to half-staff for a week in Helix’s honor. The family is planning a memorial service for June. His full obituary can be found on the city’s website.
