At TLS we agree with your assessment of the situation in that since the property itself is owned or leased by a governmental entity and not a location covered under either 46.03 or 46.035, the 30.06 and 30.07 signs would be an improper posting. However, there are people that argue when a private party is managing the property, the rules are different (this is the case with the Houston Zoo). We have yet to hear back from the Attorney General’s office on this specific matter. That being said, we believe this is a situation where your 30.06 complaint should prevail.
