The candidates for Mayor in Boise had a chance to speak to an audience together for the first time last night.

The campaign season’s first mayoral forum centered around conservation and climate change, and nearly every candidates’ answers circled back to Boise’s explosive growth.

Four of the five candidates chasing the highest office in Idaho’s capital answered questions from Conservation Voters for Idaho and made their case to a packed room.

In attendance was incumbent Mayor Dave Bieter, City Council President Lauren McLean, Adriel Martinez and Cortney Nielsen.

The Idaho Press reports, Wayne Richey, who filed for office earlier this week, was unable to be present because he entered the campaign later than others.
