High school municipal councilmember position on resume?

When I was a junior and senior in high school, I was a councilmember on my city's Arts & Humanties council. I know the usual advice is to take anything from before college off of your resume, but I don't have much other relevant experience to include and thought that since this was an official government positions as opposed to some high school club, it might be worth including. Is it worth keeping on my resume for law school applications or should I take it off? How would law school admissions view it?
