Many buildings sat totally or mostly vacant at this time, and some became dilapidated to the point where they burned down or had to be razed. Many riverfront industrial sites were abandoned or saw limited use, many were eventually redeveloped into Louisville Waterfront Park. Other issues in the 1970s through the early 1990s included a former theater district on Jefferson Street that had become dubbed the "porno district". The businesses there were seen by the city as an eyesore since they were so close to the convention center, and most were demolished or burned down by the late 1990s. A few adult book stores and bars remained in the general area as of 2007.
