So far, ExxonMobil hasn’t revealed any specific information about the new 389-acre North American headquarters just south of The Woodlands it’s apparently already begun sitework on. According to reports, all contractors working on plans for the enormous campus have been ordered to keep their work on the project secret. The new campus is meant to bring together somewhere between 15,000 and 17,000 employees now working in various locations around the Houston area and in Virginia. But documents submitted to the Army Corps of Engineers provide some detail on the plans for an enormous office park near the Harris County-Montgomery County border. The site is bounded by Spring Creek to the north, I-45 to the east, and the proposed 1,800-acre mixed-use development called Springwoods Village to the west and south. The plans were submitted by Palmetto Transoceanic, a mysterious entity that has been viewed as a proxy for the oil company in this area.
