Paving Frequently Asked Questions


When will my street be closed for the slurry seal application?
Visit for the paving schedule. 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. The day before you will receive a phone call from the city’s Code Red system.

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 I need to drive somewhere?
Park your vehicle on a nearby street that is not being slurry sealed. Use the attached map, the schedule posted at, and check area signage to plan your route and where to park.

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, etc.?
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 $.42 per square foot and is very cost effective when compared to a complete pavement overlay, which costs about $4.20 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.

Who will apply the slurry seal?
The city has contracted to apply the slurry seal. City inspectors will oversee the work and can address any issues that occur during the project.

Your street will be closed for one day for a slurry seal application. Visit for a map of when work is TENTATIVELY scheduled for your street. A couple days before your street is closed, you will receive a door hanger notice and signs will be posted along your street. 

  • Your street will be closed for one day from 7:30 a.m. to approximately 5 p.m. When the slurry seal is applied, it 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.
  • You must remove all vehicles and other objects from the street. This includes trailers, garbage cans, basketball hoops, etc. 
  • You must avoid outdoor water use if it causes water to flow onto the street. Water will hinder the slurry seal curing process. If you water your lawn or wash your car on slurry seal day, please make sure the water does not flow onto the street.

Will you get the call?
Code RED® Emergency Notification System
Add your contact information and receive alert notifications by phone, email or text. The city will use Code Red to send an alert the day before slurry seal is set to occur on your street. Visit to ensure we have your most up-to-date contact information. Using Code Red outside of an emergency allows us to practice and train new staff. You can opt out of general Code Red messages at anytime online.

The Street Maintenance Fee supports a yearly program for corrective and preventative street maintenance in Tigard. The road system is one of the City of Tigard’s biggest investments. The purpose of the Pavement Management Program is to keep our roads in the best condition possible.  Most of the paving is done in July and August because this is when we get the best weather for paving.

Tigard typically uses two types of pavement treatments: 1) pavement overlays on busy streets and on roads with severe cracks and potholes to restore the road to good pavement condition; and 2) slurry seals on streets that have lower traffic volumes and are in relatively good condition.
