San Marcos is about to do the least glamorous thing a city can do that residents absolutely notice when it is ignored.

Pave streets.

Starting Monday, Sept. 8, crews are scheduled to begin resurfacing about 21 miles of roads across the city as part of San Marcos’ annual street paving program. The work is meant to extend the life of local streets, cut down on more expensive emergency repairs later and, ideally, make the daily drive feel a little less like a suspension test.

There is a catch, of course.

Before the smoother ride comes the construction choreography: flaggers, temporary parking restrictions, door notices, signs, loose asphalt crumbs and a few days when your usual route may require a little patience.

This Is Maintenance, Not a Road Makeover

The city says the work is part of its broader annual paving effort, which is expected to continue through October 2026. Streets are selected based on pavement condition, available funding and coordination with other projects.

That last part matters. Nobody wants the city to freshen up a street only to have it cut open soon after for utility work.

Much of the project involves slurry seal, a surface treatment made from asphalt, fine gravel and water. It is designed to seal small cracks, protect the pavement underneath and extend the life of a street by roughly five to seven years.

In other words, this is not the dramatic rebuild-a-road-from-the-ground-up version of construction. It is more like pavement sunscreen.

Not exciting. Very useful.

What Happens Before Crews Show Up

If your street is on the schedule, the city says you should not have to learn that fact by finding a work truck outside your driveway.

Residents and businesses are expected to receive mailed notices before work begins. Door hangers should arrive at least 72 hours before resurfacing, and temporary “No Parking” signs will show the days and hours when vehicles need to be moved.

Typical work hours are 7:30 a.m. to 4:30 p.m., though some high-traffic areas may be handled at night or on weekends. Two-way traffic will generally be maintained, but flaggers may direct vehicles through work zones.

Translation: the street probably will not vanish from your life. It may just slow it down for a bit.

The city is also asking residents to turn off irrigation before paving work. Fresh surface treatment and surprise sprinklers are not a great pairing.

The Messy Middle Part Is Normal

Once slurry seal is applied, streets usually reopen by the end of the workday, or when traffic control devices are removed. But the road may not look completely finished right away.

The surface needs about three weeks to fully cure before permanent striping can be painted. During that stretch, drivers may see temporary lane markers, extra sweeping and loose bits of asphalt that look like the road is shedding.

Annoying? Possibly.

A sign that the project went sideways? Not necessarily.

Trash collection and regular street sweeping are not expected to change, though mail and delivery service could see temporary impacts. Residents with mobility concerns can contact the city’s construction team for help coordinating safe access.

Questions You May Have About San Marcos Street Paving

When does the paving work begin?

Crews are scheduled to begin resurfacing work Monday, Sept. 8.

How much road is being resurfaced?

The city says approximately 21 miles of streets are included in the annual paving program.

Will my street be closed?

Not in most cases. The city says two-way traffic will generally be maintained, though drivers should watch for flaggers, signs, parking restrictions and possible delays.

Why does the road look unfinished after crews leave?

Slurry seal needs time to cure before permanent striping is added, so temporary lane markers and loose asphalt material may remain for a short period.
