I want to know the answer to the following question:
What type of vacant buildings have been spared destruction?
All the background I'm provided with is that "The city itself has cleared sections of land while retaining a number of historically significant vacant buildings in order to spur redevelopment; though it has struggled with finances, the city issued bonds in 2008 to provide funding for ongoing work to demolish blighted properties.". Is that enough to answer the question?
Answer: yes
