Davidson County voters overwhelmingly voted last week to ratify four amendments to the Metro Charter.

The amendment that garnered the most attention in the runup to the vote — Amendment 1 — makes it more difficult to amend the charter by citizen petition. Specifically, the amendment requires those seeking to change the charter to gather signatures from 10 percent of registered Davidson County voters, a significantly higher number than the previous threshold, 10 percent of the number of voters who cast ballots in the most recent general election. The amendment followed repeated pushes by anti-tax activists to undo a property tax increase via charter amendment.

Amendment 2 changes physical requirements for Metro Police and Nashville Fire recruits. Previously, recruits had to meet U.S. Army or Navy recruit requirements. Now, the civil service commission will set the standards. Additionally, the amendment requires that police recruits be U.S. citizens, matching state law.

Amendment 3 makes changes to the structure of the board of health and Metro Public Health Department while substituting outdated language.

Amendment 4 creates the Nashville Department of Transportation and Multimodal Infrastructure, which has been operational since last year.
