What to expect if your street has been chosen for slurry seal application:
Prep Work
Starting about eight months prior to summer paving, prep work begins. This includes:
- White paint markings: These give guidance to the crew that will be cutting the asphalt.
- Saw cutting
- Dig outs
Construction
Summer paving work typically starts in June. This includes:
Crack sealing: Once a crack has formed in the asphalt, it will continue to grow and deteriorate the surrounding asphalt area allowing moisture to penetrate the pavement saturating the base. Some benefits to crack sealing include: preventing potholes, prevents alligator cracking, prolongs pavement life when combined with Slurry and prevents moisture from entering the subbase.
Slurry seal application: Streets are closed for one day from 7:30 AM to approximately 5 PM while the slurry seal is applied. The material looks like chocolate syrup but is much stickier and messier. 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.
Frequently Asked Questions
When will my street be closed for the slurry seal application?
Once determined, the paving schedule will be posted on www.tigard-or.gov/paving. A couple days before the closure, you will receive a door hanger notice and signs will be posted along your street. We do our best to adhere to the schedule, but wet weather and other factors can cause delays. If your street closure date changes, you will receive a new door hanger notice and the signs along your street will display the updated street closure date. You can also sign up for text message and phone call alerts to stay up to date on project timeline and impacts.
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 is likely to be postponed to another day. You will be notified of the new application date via a door hanger notice and signs along your street.
What if there is an emergency?
Should an emergency arise, emergency vehicles will be given access to the street.
What if I need to drive somewhere?
Park your vehicle on a nearby street that is not being slurry sealed. Use the attached maps, the schedule posted at www.tigard-or.gov/paving, and check area signage to plan your route and where to park.
What about garbage pickup, mail delivery, ect.?
Slurry seal applications are coordinated with the Postal Service, garbage haulers and other service providers. In most cases, you will not experience any service interruptions. Put garbage cans out early on your regular collection day, preferably at the edge of your driveway rather than in the street. Garbage haulers and mail carriers will work around the slurry seal application to provide service— although it may not be at the usual time of day.
How much does slurry seal cost and how is it paid for?
Slurry seal costs about $.30 per square foot and is very cost effective when compared to a complete pavement overlay, which costs about $3.00 per square foot. Slurry seal is paid for by Tigard residents and business owners through the street maintenance fee. This fee appears on your monthly City of Tigard utility bill.
