The Great Falls International Airport's Residential Sound Insulation Project (RSIP) was created to reduce noise inside of homes that are most affected by air traffic.

Our goals are to:

• Promote compatible land use for homes within the Noise Boundary.

• Protect the aviation operating environment.

• Improve the quality of living environment around the airport.

Pilot Phase Homes
The Pilot Phase for RSIP was completed in 2010 for 12 homes, representing the variety of housing in the Noise Boundary. Noise insulation treatment includes installing sound-rated windows and doors, providing adequate air exchange and updating heating and cooling systems so that windows can remain closed all year.

Phase 1 Homes - 2011 Construction
Homes for the next phase of construction, Phase 1, will provide similar treatments for 60-homes in the noisiest area, that were built after 1965. Funding has been secured for the design and construction of Phase 1. Construction contract was awarded in May 2011 and construction will occur between August-December 2011.

Future Phase
The Great Falls International Airport and the Stelling Engineers Design Team continue to seek federal funding for future phases. Homeowners will be sent a letter when their home has been selected for the next phase of treatment.

Historic and Environmental Issues
As with any federally-funded project, an environmental review must be completed prior to building improvements. For the RSIP, this work primarily consists of considering if homes have historical integrity (for the period they were built). For the RSIP, this historic review must begin to all homes built prior to 1965 (50 years prior to project completion in 2015).

This historic review began in January 2010 and is planned to be completed in March 2011. Future updates will be provided.
