Yeah, me. I was one of the lead designers on the Lucas Presidio campus, including the DC there...
When we were still designing the site/systems/infra we would go to BigRock Ranch a lot for meetings and vendor interviews.
Its the datacenter at bigrock which has one wall which backups to the lake on site, and the DC is in the sub-level parking garage, and its rear wall was leaking due to the pressure from the lake on the wall.
