CEDAR RAPIDS — As the 10-year anniversary of the record-breaking crest of the Cedar River — and the massive power outage that came with it — approaches, those who make sure area homes and businesses have power say things are much different now.Officials with Alliant Energy and ITC Midwest on Monday held a media availability event at Alliant’s Downtown Industrial Substation, near the corner of C Avenue NE and Fourth Street NE, to talk about how the devastating flood of 2008 helped shape the city’s current infrastructure.Should the Cedar River see a repeat of the more than 31-foot crest that occurred in 2008, the substation — along with Alliant’s River Run Substation on 10th Street SE — would remain dry.“Everything that is providing all the energy you need for your business and your life is on ground that was not affected by the flood of 2008,” Alliant spokesman Mike Wagner said.
