Frequently Asked Questions: Chip Seal

What is Chip Seal? 

Chips seal is coating of liquid asphalt and rock chips applied to the street surface to extend the life of the street. Excess rock is then swept up and an additional thin layer of asphalt, or fog seal, is placed over the new surface.

Why Chip Seal?

  • Seals the pavement to prevent water damage
  • Extends pavement life 7-10 years for a relatively low cost, compared to traditional paving
  • Leaves a renewed, black asphalt coating

Does chip seal look and feel different than asphalt?

Yes, chip seal has larger rock pieces than asphalt making it a rougher surface. Chip seal comes in both grey and black, while asphalt is typically black. Chip seal also smooths out over time as vehicles drive on it. Eventually, it will look and feel similar to asphalt.

How do I prepare for Chip Seal?

  • Inform visitors and delivery services about the planned work for your neighborhood.
  • Clear the street in front of your property of all vehicles, landscape materials, garbage or yard waste cans, basketball hoops, etc.
  • Turn off your sprinklers by 12 midnight the night before the scheduled work and keep sprinklers off until 48 hours after the second seal has been applied.

What do I do when Chip Seal is being applied?

  • Please obey “NO PARKING” signs. Cars left parked on the street will be towed at the owner’s expense.
  • Do not touch the chip seal and keep children and pets away until it is dry.
  • Do not water lawns or conduct any other activity that may allow water to run into the street before, during and after the work.
  • Please drive slowly and smoothly on the new surface for two weeks after the work is completed to allow the seal to fully cure.

What's next?

  • City crews will return in approximately one week to sweep the remaining loose gravel.
  • City crews will then return to apply a layer of asphalt oil, or fog seal, to the new road surface.

Frequently Asked Questions: Fog Seal

What is Fog Seal?

  • The process consists of spraying a very thin layer of specialized asphalt on the new pavement surface and waiting for the asphalt to cure.
  • After the fog seal product is applied, the emulsion will take time to dry and cure.

What does Fog Seal do?

  • Seals the pavement to prevent water damage
  • Leaves a renewed, black asphalt coating

How do I prepare for Fog Seal?

  • Inform visitors and delivery services about the planned work for your neighborhood.
  • Clear the street in front of your property of all vehicles, basketball hoops, landscape materials, garbage or yard waste cans.
  • Turn off lawn sprinklers by 12 midnight the night before the scheduled work and keep sprinklers off until 48 hours after the second seal has been applied.

 What do I do when Fog Seal is being applied?

  • Please obey “NO PARKING” signs. Cars left parked on the street will be towed at the owner’s expense.
  • Do not touch the fog seal and keep children and pets away until it is dry.

It is important to not drive on the freshly sealed surface to allow the road surface to harden.

  • Fog Seal must cure for at least 30 minutes before driving on the surface.
  • Driving on the freshly sealed roadway prior to proper cure may track material from the roadway to your driveway, leaving marks. 
  • Please drive slowly and smoothly on the new surface for two weeks after the work is completed to allow the seal to fully cure.

What’s next?

  • After the cure time, crews will stripe the roads and replace pavement markings.
  • Please do not drive on the freshly painted road striping or pavement markings.
