The Maintenance Department consists of two divisions, Urban and Rural, employing more than 100 employees responsible for maintaining more than 2,000 miles of roadway and more than 500 bridges and large culverts within the Districts jurisdiction.

The Urban Division is located on Adams Street in Garden City and the Rural Division is located on North Cloverdale Road. The Maintenance Departments responsibilities are pothole patching, drainage facility maintenance, pavement maintenance and repair, street sweeping, grading of alleys and gravel roads, roadside weed abatement, winter snow and ice control, and bridge maintenance. Please visit our Winter Maintenance page.

Each year, both divisions combine efforts to apply chipseal surfacing to approximately 150 miles of roadway in Ada County. Chipsealing is done to protect the surface of a street from wear, water, and weather damage. The chipseal application is done to both old and new streets to maintain existing pavement and delay the aging process. "I just had to take a moment and compliment the workers that have been doing the roads (chipsealing). They have pleasantly surprised my husband and myself by their professionalism and politeness," said Karen Sigler. "All workers (including the flaggers) have been quick, efficient, polite and professional. AND...the roads look amazing. Thank you for your consideration to us drivers."


The Maintenance Department undertakes numerous maintenance projects related to safety issues:

We replace some bridges with large diameter reinforced concrete pipe, widen some roads to three lanes providing for safe left turns (where right-of-way is existing), and replace the asphalt in intersections where rutting is severe enough to cause a safety hazard.

Periodically, the Rural Division crews assist the Boise River Flood Control with the removal of gravel from the Boise River. A total of 67,310 cubic yards of pit run was removed from the river at three different locations (Eagle Island, Eagle Bridge, and Star Bridge) in 1999.

The Maintenance Department has a Weed Abatement Program, which is very productive. With the cooperation of the Ada County Sheriff's Department inmate work release program, each year more than 20 miles of roadway and shoulders are cleared, over 250 alley blocks are cleaned, and over 1,500 cubic yards of weeds and debris are hauled to the landfill. The Weed Crew teams up with Ada County Weed Control to dig out the worst infections of noxious weeds in Ada County to prevent further spreading. This has been a very successful program with cost savings to taxpayers and the highway district. The Urban Division Weed Crew also joins efforts with Rural Division employees to work diligently on site obstructions.

In addition to installing gates to prevent vandalism and replacing bridge decks in alleys, our Urban Utility crew also performs major slope renovation to ease the concern of rocks falling from an eroded back slope.

Both Maintenance divisions continue to repair and improve street drainage throughout the county. In addition, our Grade Crews undertake minor rebuild projects where the road base is rebuilt and then the street is repaved.

Maintenance continues to enhance its strong operational partnerships with other agencies such as Boise City and Ada County through the Local Emergency Planning Committee to coordinate mitigation, preparedness, response and recovery plans associated with potential emergencies from floods, earthquakes, or other disasters. Each year, our crews assist with the sand clean up out of Crane Creek after the spring run off.

ACHD maintenance employees were recognized by the Boise Fire Department in August 2009 for their roles in responding to the Oregon Trail Fire. That fire hit Southeast Boise in August 2008. Highway District employees helped the night of the fire by providing water stored in ACHD trucks in case there was a water system failure. “You were an invaluable resource, you were our backup. You were there in the event that things went even worse than they did,” said Mitch Caldwell, Deputy Chief of the Boise Fire Department.
