Marin County Supervisor Damon Connolly was arrested on allegations of driving drunk in San Rafael, crashing into a stop sign and leaving the scene of the collision.

Connolly’s preliminary blood-alcohol tests measured 0.11 percent and 0.12 percent, police said. The legal limit for driving is 0.08 percent.

Connolly was booked into the Marin County Jail on suspicion of misdemeanor drunken driving and misdemeanor hit-and-run, said San Rafael police Capt. David Starnes.

The supervisor, who holds the District 1 seat representing San Rafael, was released pending a review by the Marin County District Attorney’s Office.

Connolly issued a statement about the arrest on Sunday after an inquiry from the Independent Journal:

“On the evening of December 20, I exercised very poor judgment by drinking at a holiday gathering and then driving home. I was detained by the San Rafael Police and it was determined that my blood alcohol level was above the legal limit. I am deeply disappointed in myself and take full responsibility for my actions.

“Drinking and driving is serious and inexcusable under any circumstances. Fortunately, no one was physically harmed in this instance. As an elected official, I work hard to maintain the trust of the public. I will take whatever steps necessary to make things right due to my conduct, including a commitment to eliminate alcohol from my life.

“I have apologized to my wife and two daughters and I want the community to know how profoundly sorry I am. I love this community and hold myself to the absolute highest standards of personal conduct and integrity. Unfortunately in this instance I fell far short of that standard.”

The incident happened at about 11:30 p.m. Dec. 20 at the intersection of Las Gallinas Avenue and Montevideo Way in the neighborhood south of Lucas Valley Road. Police went there after receiving a call from someone who heard a collision.

An officer found a stop sign knocked down into the center median and crash debris from a blue vehicle, said Starnes, the police captain. The officer found an unoccupied blue Prius with fresh damage parked outside a nearby residence.

Police determined it was Connolly’s car and Connolly’s residence. Shortly after midnight, police contacted Connolly at the home, and he acknowledged he was the driver.

“He was completely cooperative through the entire investigation,” Starnes said.

Connolly — a former deputy attorney general, Dixie school board member and San Rafael councilman — was elected to the Board of Supervisors in 2014. He secured another four-year term in June after running unopposed in the primary.

Connolly said he does not plan to step down as a result of the arrest.

“I’m taking all steps to assure the Board of Supervisors and my constituents that I will continue to perform my job at the same standards that I have demonstrated over my many years of public service,” he said.
