February 13, 2017 Update: ACHD has its entire fleet of 22 sweepers working in the
nine zones across Ada County, matching operators to the routes they know intimately to remove sand
from winter maintenance. Updates on when the sweepers will hit areas within the zones,
information we hope to have available soon.
The sweepers will focus first on arterial and collector roads, and streets that drain to and can impact the Boise River. It is estimated that the first phase will take four weeks. The focus will then turn to residential areas. It may take up to 10 additional weeks to sweep the entire county.
The sweeping plan is divided into nine zones. This enables crews to meet or exceed the National Pollutant Discharge Elimination System (NPDES) permits issued by the EPA, and better serve the people in Ada County. The following is the general schedule the sweeping crews follow every year:
Throughout the year, crews also respond to emergencies and calls across Ada County.
