HP is in the process of vacating five, 8-10 story buildings on the 249 campus and consolidating the employees in the remaining buildings (I work in one of these buildings). In addition, there are 3 other office buildings and a manufacturing building that are already vacant (I think this is what the Chronicle article refers to for UH as there are 3 office buildings, 1 manufacturing building and 4 parking garages... this section of campus is kind of separate from the rest.) I've heard Exxon is one of the new tenants and I've also heard the UH rumors before the Chronicle article. There certainly would be plenty of space for someone other than Exxon. I think the Prarie View concern is because of their "campus" at Cypresswood and Stuebner Airline.
