Louisville area preservationists want four buildings on the proposed Center City site to be declared historical landmarks.The old Water Company headquarters, Falls City Theater, Odd Fellows Hall and Bosler’s Garage date as far back as the 1880s. The city plans to purchase the buildings and the rest of the block this month. It will then be leased to the Cordish Company who will build the Center City entertainment district on the land.Steve Porter is the spokesperson for the OPEN Inc. preservation group. He says Cordish has built around historic buildings in the past.“Their track record on doing things in historic buildings is good," he says. "We just want to remind everyone that we have that same possibility here, where those four buildings could be reused.”Porter says he’s not against Center City, but wants the buildings preserved. OPEN Inc is gathering petitions to submit to the Landmark Commission. If the commission gives the buildings landmark status, Cordish will have to apply to modify or raze them.
