THey did do an EIS, just not a very good one. It was another of TXdot's lapse of judgments. TxDot is one of the dumbest organizations in the country, not to mention one of the laziest as well. Here we have a 3 mile span of road that is going to be one of the hottest subjects in town once construction starts, you'd think they'd pay attention to as many details as they could up front rather then waiting for the public, which of course they were going to find out, to notice the terrible job they did on the EIS. They nearly left out the topic of the Aquafer on it.
Having said that, you seem like a reasonable guy, you know as well as I know that construction on that road would have gotten rid of congestion in the area, thus reducing pollution from vehicles, and there would have been every single control you'd think of in order to keep ANYTHING from even potentially damaging the aquafer. Unlike the home builders in the area who I've actually seen discard "empty" paint cans into creeks and drainage ditches.
