Sonoma Street Closures Start For Slurry Seal

SONOMA VALLEY, CA — Sonoma crews will begin applying slurry seal to streets across the city Sept. 8, following a week of preparation work that includes removing pavement striping and sealing cracks.

The city’s 2026 Citywide Slurry Seal Project will start with relatively minor roadway preparation the week of Aug. 31.

Crews expect to begin removing existing pavement striping Monday and perform crack sealing later in the week, according to a city announcement.

The larger slurry seal operation is scheduled for Sept. 8-10.

Slurry seal protects pavement from water and sun damage, extends roadway life, and reduces the need for more costly repairs in the future.

Crews plan to work on the following streets:

Tuesday, Sept. 8

• Bragg Street, from Clay Street to the end of the street
• Clay Street, from west of Bragg Street to Broadway
• Church Street, from Fourth Street West to Third Street West
• Third Street West, between Andrieux Street and Bettencourt Street

Wednesday, Sept. 9

• Clay Street, from Fryer Creek Drive to west of Bragg Street
• Napa Road, from the eastern city limit to Broadway
• Third Street West, from West Spain Street to West Napa Street
• Third Street West, between Andrieux Street and the Sonoma Marketplace shopping center driveway

Thursday, Sept. 10

• Third Street West, between East Napa Street and the Sonoma Marketplace shopping center driveway
• Leveroni Road, from the western city limit to Broadway
• Oak Lane, from Chase Street to the end of the street
• Fourth Street East, from East Spain Street to East Napa Street
• Bettencourt Street, from Third Street West to Second Street West

The city said the preliminary schedule could change because of weather, field conditions, or other construction considerations. Crews will also perform additional pavement preparation and striping during the project.

The contractor will notify residents on streets scheduled for treatment in advance. Crews will post no-parking signs at least 48 hours before work begins, identifying the dates and times when parking restrictions apply.

Crews may temporarily close streets to traffic while they apply the slurry seal and allow it to cure. Drivers should expect delays and use alternate routes when possible. Emergency vehicles will retain access throughout the work.

The city asked residents to follow posted parking restrictions and avoid driving or walking on newly treated pavement until streets reopen.

Construction schedules remain subject to change, and the city will provide updates as work progresses.
