Should New Orleans be rebuilt? A panel of Wayne State University academics will debate the question today in the Student Center Building , 5221 Gullen Mall. Some of the experts will argue that it will cost too much to reconstruct the flooded city, which will be vulnerable to future natural disasters. Others are expected to take the position that the city is too important not to rebuild. The answers, WSU Professor Robin Boyle said, could have important implications for Detroit . \"I come down on the side that the city has to be rebuilt,\" said Boyle, who chairs the department of geography and urban planning. But, in doing so, he said, the planners must consider setting aside property that isn\'t built on to protect the city from flooding. \"We\'ve taken the sponge away,\" Boyle said. \"We have to put it back.\"
