WATERLOO/CEDAR FALLS – The Cedar Valley is experiencing a flurry of new development and reinvestment…from downtowns, to riverfronts, to recreational facilities, according to Corridor Business. The Cedar Valley SportsPlex, a 130,000-square-foot recreational center being built in downtown Waterloo, is part of that healthy boom. It is also part of something called the Blue Zones initiative. The Blue Zones Project is a collaboration between Wellmark Blue Cross and Blue Shield and Healthways as part of Gov. Terry Branstad’s Healthiest State Initiative, an effort to make Iowa the healthiest state in the nation by 2016.
