The Hawks have qualified for the playoffs six times in 12 seasons with the Cubs, including the last two years.
"We are so excited that the Cubs have shown their support for the Boise area," said Hawks president/general manager Todd Rahr in a press release. "The loyalty they are showing the Hawks and patience they are giving us to improve the facilities here says a lot for their dedication to player development and to our great city and surrounding area."
The Cubs have sent their top draft pick to Boise in each of the last eight seasons.
The organization hasn't announced if it will renew their player development contract with Class A Daytona and Class A Peoria. Triple-A Iowa has an agreement through 2016 and Double-A Tennessee has one through 2014.
