Thanks for the welcome!
The Doan building on E.22 and Chester was purchased by the university around 2001. As far as I can tell originally the plans were for a parking structure there. Later on when the first master plan came out, the plans called for redevelopment of the building, but clearly that idea was not feasible. Sometime before I started at CSU (in 2009) the university did remove the loading dock area by the parking lot on the corner of 22nd and Chester, but thats really all I know about the Doan.
I am excited to see what comes of the Stillwell renovations, as well as whatever the future holds for the new Science building. Our existing science facilities are QUITE outdated to say the least.
