Chip Seal Information for 2022

Asphalt deteriorates over time because of the sun and weather. Chip Seal helps seal the surface and helps protect the road. Some preparation work will take place throughout the spring, and the Chip Seal process traditionally begins the first week in June.

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.

Where will we be this Year?

This year ACHD will be chip sealing most of Zone 3 in the south Boise and Kuna areas, as well as portions of Five Mile, Amity and Maple Grove roads that are adjacent to Zone 3. Bogus basin Road, Curling Drive to the county line and Shoshone Street, Rose Hill Street to Overland Road will also be chipsealed.

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".
