What's fishy? Haithcock obviously didn't care about straightening Harrison, but didn't want to ruffle any feathers by making demands of the University Center developer. Fioretti sees the straightening as more of a priority, and he feels more comfortable exercising leverage over CPS.
The design of the new segment of Harrison could be problematic. What's to become of the little triangles of land to the north and south of the new alignment? I can only hope the city doesn't try to cram parking spaces there. In New York or Tokyo, those would become developable parcels, but that's way too much to hope for in Chicago...
I'm also disappointed in the park usage. The site isn't big enough for a soccer field or football field. These greenspaces usually fail utterly. The only successful one I can think of is in
Battery Park City, where careful attention was paid to the edge condition, which maintained the urban feeling of the street while allowing the sports field to become secure (and protect against fly balls).
