Hennepin County commissioners are scheduled to vote Tuesday on their own proposed pay raises for 2017 and 2018.

The County Board will vote on a 2.5 percent pay increase in 2017 — the same percentage raise that county staffers got for 2016 — and a 2.5 percent pay hike in 2018. If they approve both increases, each board member will make $113,498 by 2018, compared with their $108,093 annual salaries this year.

State law requires that county commissioners adopt salary changes before the general election.

Hennepin commissioners typically follow the salary increases granted to other county employees. From 2011 through 2013, they froze their own salaries, then raised them by 2.5 percent each year in 2014, 2015 and 2016.

In Ramsey County, commissioners approved 2.5 percent raises earlier this year. Most of them make $87,884.

Washington County commissioners once again this year are forgoing raises, continuing a practice of freezing their salaries since 2009. At $52,713, Washington commissioners are the lowest paid County Board members in the seven-county metro area.
