2021 Pavement Preservation Project
Overview of Project
The 2021 Pavement Preservation Project is scheduled to begin the week of September 20th and last for approximately four weeks. Residential areas to be slurry sealed include the neighborhoods of Vintana and Vintage Greens. No parking will be allowed on the designated streets during the hours of 7:30 AM to 5:30 PM on the day shown in the Slurry Seal Phasing Map, available at the link below. Please follow local signage indicating when parking or driving is not allowed.
The Contractor (VSS International) or Construction Manager (Green Valley Consulting Engineers) for this project will distribute paper notices to affected residences indicating the date of slurry seal application. If the date of application changes, residents will be notified again. Residents are encouraged to check the Slurry Seal Phasing Map at the link below for the most up to date information. Signs indicating “No Parking” will be posted 72 hours in advance of slurry seal application on specific streets. If your garbage collection day coincides with the slurry seal application, please place your garbage and recycling carts in the street the night before.
The Traffic Relief Act for Sonoma County (Measure M) provides for a ¼ cent sales tax to be used to maintain local streets through the Sonoma County Transportation Agency (SCTA). Measure M is a reliable fund source for on-going local street maintenance projects such as this year’s 2021 Pavement Preservation Project.

Slurry Seal FAQs
What is a slurry seal?
Slurry seal is an asphaltic emulsion product consisting mainly of water, petroleum, aggregate, and cement. It is blended on-site in a large truck and then applied evenly across the entire street surface. The slurry seal is typically 1/4 of an inch thick.
What is the purpose of slurry sealing?
Streets deteriorate over time with exposure to weather. Applying a slurry seal counters the effects of weather and extends the life of the street. In addition to providing a new wearing surface, slurry seal will also correct minor street defects that have appeared over time.
Why does a street in fairly good condition receive a slurry seal as opposed to a more deteriorated street?
Slurry sealing is a preventative maintenance treatment that should be applied before a street begins to deteriorate from extensive cracking, raveling, or potholes. Streets with more advanced deterioration must be fixed with an asphalt overlay or base reconstruction, both of which are expensive. A slurry seal is not meant to treat advanced pavement deterioration such as alligator cracking or potholes.
How will the slurry seal application affect me?
Your street will be closed for one day, from approximately 7:30 AM to 5:30 PM. You will not have vehicle access to your driveway during that time, though pedestrian access will be maintained on sidewalks. Slurry seal takes several hours to dry. During that time, motorists, pedestrians, and pets must stay out of the slurry seal so as not to ruin the application and to avoid getting slurry seal on vehicles, shoes, and paws. Slurry seal will take longer to cure in shaded areas.
What can I expect before the slurry seal process?
Public outreach through door hangers or paper notices will typically occur two weeks prior to the start of work. No parking signs will be placed along the street 72 hours before the slurry seal application.
What can I expect during the slurry seal process?
All vehicles and objects must be removed from the street including trailers, basketball hoops, etc. Garbage and recycling carts cans can be left in the street if your collection day coincides with the slurry seal application. Just prior to the slurry seal, the street is swept with a mechanical street sweeper. The spreader truck will then place a liquid mixture of slurry seal on the street. While motorists can drive on the slurry seal application a few hours after it has been applied, it takes two weeks to fully cure. During the first few hours while the slurry cures, motorists, pedestrians, and pets must stay out of the slurry seal so as not to ruin the application and to avoid getting the seal on vehicles, shoes, and paws.
What can I expect after the slurry seal process?
Once the slurry has cured for several hours it will be reopened to traffic. At this time the slurry is very tender. Any sharp turns and turning of vehicle wheels while not moving will tear the surface. Please be sure to avoid making sharp turns or turning your wheels while not moving to keep the street looking its best. It will take several days before sharp turns won’t cause tears in the surface of the slurry seal. Street sweeping will then typically take place after a week. Please be sure to remove objects from the street so the sweepers can pick up the loose slurry materials. When the slurry has cured for one to two weeks, traffic striping will be installed. As the slurry seal cures it will turn from brown to black and the street typically has a sandy or gravel-like coating. This sand is picked up by street sweepers once the curing process is complete. Please check the Town’s street sweeping schedule the first month after slurry seal placement and be sure to clear the street so the sweepers can pick up these loose materials.
What can I do to help make the work go smoothly?
- Plan ahead and anticipate parking issues and how you will get in and out.
- Park on nearby, unaffected streets if necessary.
- Try to reschedule any visitors or deliveries.
- Keep children and pets away from the street while work is being performed.
- Whenever possible, avoid construction areas and use alternate access routes.
- Check your shoes before walking into your house. The loose rocks can scratch wood floors.
- Respect construction signs, cones, and barricades. Do not drive into areas that are coned/barricaded off.
- Drive slowly; the pavement can be slippery because of loose gravel or sand.
- Do not drive on the treated streets until the lanes have been reopened to traffic.
- Warn your children to be careful while riding their bicycles until the loose gravel/sand is swept up.
- Continue to park your car off your street or cover it until the initial sweeping is completed. Loose gravel or slurry mix thrown up by speeding vehicles could damage your car’s paint.
- Avoid outdoor water use if it causes water to flow onto the street. Water will hinder the slurry seal curing process. Do not wash your car or water or water your lawn on your slurry seal day.
Scuff marks are appearing in the slurry!
Slurry seal placed on neighborhood streets tends to get more scuffing and blemishes (particularly adjacent to driveway approaches) than through streets due to the sharp turning typically being done as a resident exits their driveway or a parking space. These marks are superficial and do not constitute a slurry failure.
What if I need to drive somewhere?
Park your vehicle on a nearby street that is not being slurry sealed. Check the area signage to plan your route and where to park. The streets are phased to provide room for parking on adjacent streets.
What if there is an emergency?
Should an emergency arise, emergency vehicles will be given access to the street.
What about garbage pickup, mail delivery, or other deliveries from service providers?
All work is coordinated with the postal service, garbage haulers, and other service providers. In most cases, you will not experience any service interruptions. Garbage haulers and mail carriers will work around the slurry seal application to provide service, however, it may not be at the usual time of day.
What if it rains?
Light rain or passing showers may not delay the slurry seal application, however, slurry seal cannot be applied in heavy or steady rain. If we have or anticipate significant rainfall, the slurry seal application may be postponed to another day.
