Another Try to Place Levee Sites on Historic List An advocacy group is making a second attempt to place a site where a levee breached during 2005's Hurricane Katrina on the National Register of Historic Places. This time the group's application is trying to get around opposition by the U.S. Army Corps of Engineers, which built the ill-fated flood walls. Last year, the National Park Service rejected an application by Levees.org to have two breach sites placed on the register. One of those sites was owned by the corps. This time, the organization is focusing solely on a breach site that is not owned by the corps. So, corps officials who oppose the application won't have a role in the process.
