Slurry-seal work lands September 21-23 after rain delay
The city's preventative street maintenance was pushed back two weeks; the official schedule lists every affected street.
SONOMA: The city's 2026 slurry-seal project, originally set to begin September 8, was rescheduled to September 21-23 after rain moved the work back two weeks. The preventative maintenance coats streets with a thin sealant layer that extends pavement life and postpones far more expensive reconstruction.
The city published a street-by-street schedule for the three days of work, so residents can see exactly when their block is affected. Slurry-seal days mean no parking on the treated streets, brief access restrictions and fresh blacktop that needs hours to cure before traffic returns.
Rain delays are routine for this kind of work: sealant needs dry pavement and a clear forecast window to bond properly. Pushing the project rather than rushing it in marginal weather is the difference between a seal that lasts years and one that peels by spring.
Preventative maintenance is the unglamorous end of street spending, and the cost-effective one. A slurry seal costs a fraction of a grind-and-overlay, which costs a fraction of full reconstruction. Cities that stay on schedule with seals spend less on streets over time; cities that defer pay later.
With the September 21-23 window now complete, the city's 2026 street program turns to whatever the pavement management plan has queued next. The Post will keep the official schedule linked for residents checking whether their street made this year's list.
