I was finally able to find a permit for the property that is east of Costco.

The only filing is a weird right-of-way document that took forever to find. It was a permit to reshape and downsize the pond on that property.

As you can see in the second image, they are planning something similar to the Chisholm Creek lake with retail, restaurants and office structures all around. There hasn't been any type of building permits but it looks like they are reworking the pond in the hopes of luring businesses.
