Flood control scams?

White Settlement has a real flood control problem, one where homes actually flood.  They voted to spend money years ago to correct the problem. 

So, what happened?

Congress and the Corp of Engineers, that's what.  Read the excerpt below from the Fort Worth Star-Telegram.

In the meantime, the cost of the project, which is funded by White Settlement and the Army Corps of Engineers, has increased. After voters approved the $6 million, Congress placed a moratorium on the $7 million in federal funds that wasn't lifted until 2007 because of the wars in Iraq and Afghanistan. During that time, costs increased and the estimated cost for the project was $16.2 million, but now it is more than $18 million.

One of our sources tells us the same thing happened in Haltom City.  WHERE are the cities supposed to come up with the additional money?  If they call it a vision will that help?  If real flooding problems cost more than estimated, what will happen with the Trinity River Vision estimate?
