Due in part to aircraft noise in south Minneapolis and surrounding suburbs , proposals were made in the 1990s to build a new airport on the fringes of the Twin Cities metro in Dakota County to handle larger jets and more international traffic . Minneapolis and other neighboring cities were concerned that such a move would have a negative economic impact , so an arrangement was made where the Metropolitan Airports Commission would outfit many homes in the vicinity of the airport with sound insulation and air conditioning so that indoor noise could be reduced . A citizen group named ROAR ( Residents Opposed to Airport Racket ) was created in 1998 and helped push the MAC to make these concessions . Later , in 2004 , the MAC voted to reduce funding for the soundproofing projects , saying in part that the economic climate had turned in the wake of the September 11 attacks . Minneapolis Mayor R. T. Rybak , who had been a founding member of ROAR , promised that the city would challenge the changes
