Boise voters could see partisan, countywide ACHD elections under pending Idaho bill
SB 1356 would remake how Ada County Highway District commissioners are elected, shifting a key Boise-area road governance system toward countywide partisan races in 2028 if signed.
Boise residents who care about street projects, traffic flow, and public right-of-way rules have a new statehouse item to watch. BoiseDev reported on April 2 that Senate Bill 1356 cleared the Idaho Legislature and reached Gov. Brad Little. The governor’s latest publicly posted daily bill-action sheet shows SB 1356 was delivered at 5:00 p.m. on April 2 and is due by April 8, with no action listed on that posted sheet.

That matters in Boise because the Ada County Highway District is not a Boise city department. It is the countywide highway district for Ada County, including Boise, and ACHD says its five elected commissioners set policy affecting county roadways and public right-of-way. In practice, that means the board helps shape the rules and priorities behind many of the streets, intersections, bike facilities, and corridor decisions Boise residents use every day.

How SB 1356 would change ACHD elections
ACHD’s current system is district-based and nonpartisan. The agency’s board page says the commission is a nonpartisan, locally elected body made up of five members divided into geographic districts. ACHD’s election page says those seats are local nonpartisan offices and that a candidate must live in the ACHD subdistrict he or she wants to represent.

BoiseDev reported SB 1356 would replace that structure with countywide partisan elections for ACHD commissioners. The same report said lawmakers amended the bill so the change would begin in 2028, not in the 2026 election cycle. BoiseDev also reported the measure passed the Senate 19-16, then moved through the House State Affairs Committee 10-4 and the House floor 47-20 before going to the governor.

Why Boise readers should watch it
This is mainly a governance story, but it has practical local stakes. Who sits on the ACHD board can affect how transportation priorities are debated across Boise and the rest of Ada County, including questions around traffic flow, street design, and bike and pedestrian investments. What has not happened yet, based on the latest publicly posted governor materials, is a final decision from Little. For now, the watchpoint is whether he signs, vetoes, or lets the bill become law before the April 8 deadline shown on the latest posted tracking sheet.
