After the 9/11 attacks, municipalities all over the country took note of the breakdown of communications between rescue workers during a moment of crisis. Many set aside funds to build emergency communication centers, like the ill-fated one located at Seven World Trade. In 2003, county voters in Tucson set aside $92 million to build a command center where police, fire, and emergency personnel could coordinate emergency responses. The county Board of Supervisors selected the former Valley National Bank building on East 22nd Street as the site for the new command center. But now preservationists are concerned that sections of the Brutalist building, designed by local architects Cain, Nelson, Wares & Cook Architects, will be destroyed.
