24/7 Trauma and Biohazard Cleanup in Jenner, CA

Jenner, also known as Jenner-by-the-Sea, is a small coastal town and census-designated place in Sonoma County located on the Pacific coast where the Russian River meets the ocean, with State Route 1 running through town.

Jenner was historically part of the Rancho Muniz, and the town is named for Dr. Elijah K. Jenner, a dentist and inventor from Vermont who came west in 1850 and settled with his family near the mouth of the Russian River in 1854, in what became known as Jenner Gulch.

Working as a gold miner, Elijah Jenner designed a pump that could raise water 100 feet high, and the model included in his patent application was made of pure gold - said to be the only golden model the U.S. Patent Office has ever received.

Immediately south of Jenner is Goat Rock Beach, a unit of Sonoma Coast State Park where Pacific harbor seals haul out at the river mouth, and directly north the Jenner Headlands Preserve overlooks the Jenner Estuary.

Construction of a jetty at the mouth of the Russian River at Jenner began in 1929 in an effort to keep the river mouth open for shipping.

Jenner had a population of 122 at the 2020 census, down from 136 in 2010, and its residents lived in 80 households averaging just 1.52 people each.

Jenner has about twice as many houses as households: of its 161 housing units in 2020, only about half were occupied year-round, the rest being vacation homes in this popular coastal getaway, and 78.8% of occupied homes were owner-occupied.

Jenner is an older community, with a median age of 63.8 years in 2020 and about 45% of its residents aged 65 or older.

Jenner experiences a cool-summer Mediterranean climate with about 37 inches of rain a year, and its summers are often overcast and drizzly under the marine layer off the Pacific.

Jenner's students are served by the Monte Rio Union Elementary School District and the West Sonoma County Union High School District.
