ACHD Rolls Fleet to Pick Up 20,000 Tons of Traction Sand

Ada County - After a winter of extreme weather conditions and unusually heavy (and continuous) snowfall, the Ada County Highway District (ACHD) has turned its attention to removal of more than 20,000 tons of sand on Ada County roadways.

Starting today (February 13), ACHD's entire street sweeping fleet will begin a full-force effort to sweep each of the nine sweeping zones. As with snow removal in recent weeks, ACHD and other local governments urge residents to sweep sand from public sidewalks near their homes, which will increase mobility and safety for all users.

While road sand increases grip for motorists on snow and ice, it can create air and water quality issues if the material is left in place after storms.

The sweepers will work each of the nine zones throughout the county, focusing first on arterials, collectors, and roads that could impact the Boise River. It is estimated that the first phrase will take four weeks. The focus will then turn to residential areas. It may take up to 10 weeks to sweep the entire county.

Sweeping is weather-dependent. While we currently have warm and dry conditions compared to December and January, spring is still weeks away and new storms are possible. Sweepers use water and cannot be used in freezing conditions.

In order to avoid conflicting schedules, ACHD crews will not sweep roads when the trash is scheduled to be collected.

The Ada County Highway District operates 22 sweepers that have an average operating speed of three miles per hour. Crews will work five days a week, 10 hours a day until the sand has been removed.
