Chip Seal Information for 2019

As part of the ACHD maintenance program crews chip seal street surfaces (including new streets) to protect them from water and weather damage, so they stay in good condition. Crews start preparing the roadway for chip sealing in early spring, as the weather allows.

The 2019 chip seal season is expected to begin as early as May 28, 2019 and last until late August or early September. This year ACHD will resurface approximately 411 lane miles of roadway.

2019 Chip Seal Schedule And Updates

The chip sealing process consists of five phases:

  • sweeping prior to the chip seal
  • applying the chip seal
  • sweeping excess chips
  • applying the fog seal
  • sweeping after the fog seal
On-street parking will be affected during each phase. Temporary No Parking signs will be placed in most areas. When you see these signs, it is an indication that crews will be in the area within approximately the next 24 to 48 hours. This is a mobile operation and it is weather and equipment dependent.

We appreciate your patience during this time as we maintain your roadways and strive to maintain our roadway rating as, "the best in the Northwest".
