I work near there so I drive by all the time. I can tell you they put 10 feet of dirt there because they didn't rip out all the foundational cement barriers that were up where trucks used to back in for deliveries. They just covered it up with a LOT of dirt.
As for a park, I'm not sure. A lot of their property is just nice and landscaped. Carrier already has a park and ball field on their premises. It's clearly labeled as being for company use only. Otherwise there would already be a cache there, I promise you.
