The San Mateo County Transportation Authority, which administers the voter-approved, half-cent Measure A sales tax to fund transportation projects in San Mateo County, swore in three reappointed members and elected new board officers at its monthly board meeting.

Mark Church, Rosanne Foust and Rosalie O’Mahony were sworn in to new two-year terms. The board then elected Foust and O’Mahony as chair and vice chair, respectively.

Church represents the San Mateo County Board of Supervisors on the TA board. He is the county supervisor for district one, and has served on the TA board since 2001.

Vice Chair O’Mahony represents central county cities on the TA board. She is the vice mayor of Burlingame and has served on the TA since 2006.

Chair Foust, represents south county cities on the TA board. She is the vice mayor of Redwood City and has served on the TA board since 2005. She succeeds John Lee, the TA representative for county cities-at-large and city councilman for San Mateo.

“I’m extremely honored to have been elected chair,” said Foust. “The TA has funded so many important transportation projects in our county, and I look forward to continuing the work that has earned this board the trust and respect of county voters.”

The TA board has seven appointed members, representing the county government, the cities throughout the county and the San Mateo County Transit District. The TA meets the first Thursday of each month at 5 p.m. at 1250 San Carlos Ave., in San Carlos, two blocks from the Caltrain station.
