More details on Exxon’s new campus

Chronicle real estate reporter Nancy Sarnoff has written repeatedly about the developing plans for Exxon Mobil’s consolidated Houston-area campus just south of The Woodlands — a massive complex that could provide space for more than 17,000 employees when completed.

Houston real estate site Swamplot has an update on the plans, which have been filed with the U.S. Army Corps of Engineers:

The plans, prepared by environmental consultants for the project, show the outlines of more than 2 dozen Z-shaped buildings and 4 giant parking garages arrayed in four quadrants within the outline of a large ring road.

The plans were submitted to the Corps as part of a request for approval to fill 4,888 linear feet of waterways on the site that currently drain into Spring Creek and mitigate impacts on less than acre of wetlands. (According to the public notice posted by the Corps in January, the organization’s “preliminary review” indicates that no environmental impact statement will be necessary for the project.)

Trees are being cleared from the massive plot, according to Swamplot, meaning some decision has been made on moving forward with at least part of the project.
