A longtime Mill Valley resident and real estate agent died in a single car crash near Lakeville Road east of Petaluma on Friday afternoon, according to the Sonoma County coroner's office.
Marguerite Marie Burbank, 61, was driving a 2006 Audi A4 on a private road between the Riverside Equestrian Center and Lakeville Road when the crash happened sometime around noon, California Highway Patrol officials said.
The Audi drifted to the left for an unknown reason, went off the north end of the roadway and overturned as it drove into a ditch full of water, according to the CHP. Only the front wheel was visible, and a passerby notified the CHP around 3:50 p.m. that a car was upside-down in the ditch.
The Sonoma County Fire Department responded with the CHP and removed Burbank and her two deceased dogs Molly and Max from the vehicle. Burbank was pronounced dead at 4:26 p.m. An autopsy is scheduled for today.
CHP Officer Jon Sloat said the private road is straight at the point where the car went off the roadway, and that either a medical emergency or inattention might have caused the crash.
Burbank, a longtime horse enthusiast, was showing a horse at the Riverside Equestrian Center at 76 Lakeville Road and was believed to be on her way home when the accident occurred, Sloat said.
Burbank was well known through Mill Valley and southern Marin. She had been a real estate agent since 1989 and was most recently with in Mill Valley.
"She was an avid rider and horse-lover having just finished up a happy day doing what she loved - riding her beloved Stuart, and was on her way to do errands," said Marin Association of Realtors President David Smadbeck in a statement. "Everyone is shocked, broken-hearted and in complete disbelief."

The family is asking that donations in her memory be sent to the Mill Valley Rotary. Check back later this week for more reactions to Burbank's passing.
