I seriously wonder at the wisdom of designating ALL the residential units as low-income housing. The pre-agreement scheme seems to say that the theme of the redevelopment is going to be an artist colony, but are there really 500 artists in Fort Worth who are going to be willing to live in that building? Is the idea to attract them from other places? If the artists don't show up who is going to take up the slack? What is an artist, and who is going to make and enforce that definition? In general it seems bad practice to concentrate a large number of low income, un-and under-employed people in one place, especially where employment opportunities may be overwhelmed by job-seekers. I am all for providing below-market housing opportunities, just not massive numbers of them massed together. Wasn't this the failed premise of the high-rise slums created by urban renewal programs of the 1950s and '60s?
The upper floors of this and other buildings will appeal to higher-income residents, whose rents would help to offset the reduced rates for "artists" and others living on lower (less-desirable) floors. The roof might appeal to someone wanting to provide an entertainment venue of some sort, and there is probably some call for offices for professionals who would provide services for residents and others, most likely on more accessible lower floors.
Is the thinking of the owners to secure more grants and tax-dodges by providing rent-subsidized ("section 8" or similar) housing?
