Turns out the city knew about the sand under the Trinity. Better yet, the city told the Corps of Engineers about it from the start. Here’s Schutze:
So here’s the deal. This means the city did do the geo-tech. The city says it did give the geo-tech to the Corps. The Corps did give the city the go-ahead for the project. The Corps then stopped the project and said it was shocked, shocked, when sand came out of a hole.
Now Schutze doesn’t know what to do. Can’t blame the city anymore.  But blame the Corps? He’s been pumping the Corps against the city for a year or more. What to do? He’s got to blame somebody. After all, it’s the Dallas Observer. It’s their schtick.
