BOISE -- An open house about Boise Airport's Master Plan became heated very quickly Wednesday night. It was meant to update people about future development plans to meet aviation demands.

However, almost everyone who attended voiced their concerns about noise issues and how they fear it's only going to get louder. The room was packed, with many frustrated people who felt their voices aren't being heard.

Boise Airport's noise study accepted by the Federal Aviation Administration this year is an issue for hundreds of people who live near the airport.

"This is a noise map. This is 2020, just a few years from right now, it's a contingency plan," one concerned resident in the crowd told the airport director during the open house. "It does look like you're looking at it as though it might happen."

One of people's biggest worries is the fact that the noise study talks about the possibility of fighter jets coming to Boise, and because of that, hundreds of homes could be purchased since they fall within that future noise exposure zone.

"There is no plan at this point in time for the military to base additional aircraft at Boise," BOI Airport Director Rebecca Hupp told those in attendance. "My point is it is a forecast."

Hupp says whether military jets transit - or are based here - is out of their control, and is up to the military.

Because Wednesday night's meeting was about the master plan, airport officials felt it was not the place to express those concerns.

"Concerns about the noise study that was completed and accepted by the FAA is not related to the master plan study that is happening currently," BOI Airport Public Information Officer Sean Briggs told KTVB.

But residents say the two are absolutely connected, especially when you're talking about growing and developing the airport.

"Part of that has got to be dealing with noise," Vista Neighborhood Association President Dave Kangas said. "We don't want fighters in that master plan."

Ada County Assessor records show the City of Boise has already purchased a few properties on S. Pond Street in Boise, which is within the airport's 2020 Noise Exposure Map.

Hupp says the best time for people to give input on noise would be during the "Alternatives Development'" phase of planning, which is set for the middle of next year.
