Fires and Floods

Go hand and hand.  Who would have thought?

FEMA fills you in.  So if a wild fire can cause a flood downstream, what else could?

Flood mitigation methods will also be discussed because flooding risks can jump after a wildfire, even in areas far from the fire that were not previously considered as having moderate or high flood hazards.

Flooding may be the last disaster wildfire survivors think they should guard against. When fire burns away vegetation, however, there is nothing to soak up the water from the heavy rainstorms that can occur in Texas. Storm runoff can cause severe erosion, mudslides and flooding.  

While the highest risk of flooding is for properties directly impacted by fire, it also rises for homes downstream or below scorched areas.

Hitting the nail on the head

Is what the New York Times keeps doing.

(This story, "As Thailand Floods Spread, Experts Blame Officials, Not Rains", originally appeared in The New York Times.)

On the other side of the world, yet it sounds so familiar...

As some of Thailand’s worst flooding in half a century bears down on Bangkok — submerging cities, industrial parks and ancient temples as it comes — experts in water management are blaming human activity for turning an unusually heavy monsoon season into a disaster.

The main factors, they say, are deforestation, overbuilding in catchment areas, the damming and diversion of natural waterways, urban sprawl, and the filling-in of canals, combined with bad planning. Warnings to the authorities, they say, have been in vain.

Those who tried to warn them have been called crazy.

Ain't so crazy now, is it?

Same story

Another story from Texas with all the same factors - gas drilling, floods, politicians, tributaries, FEMA, mortgage, insurance...Any of this sound familiar?

Read about it in the Fort Worth Weekly.  WHO's next?

The first change occurred just four months after they moved in, when Devon Energy built a gas well pad next to their fence line, ruining the view for months and sending toxic residue into their backyard every time it rained (“Paradise Lost”,  June 18, 2008).
 
One month after the pad appeared, said Annette, “We got slammed by a flash flood that nearly entered the house. A neighbor called to ask if we were all right, and then she told us we might be in a flood plain.”

The flood plain question “had come up once — that some of the land but not the house was in a flood plain” during discussions before the sale, Annette said, “but when it did, the realtors produced several reports showing that the property was not in the flood plain.”

“We never would have purchased the house if there were any flood issues,” said Michael. The couple did know that runoff from heavy rains had washed into their pool and come close to the house.
People involved in the sale of the property to the couple disagree. They later maintained in court that the Daniels were or should have been aware that the property they were purchasing was in a flood plain.

After the neighbor’s comment, the Daniels began to look into the issue and eventually got in touch with Parker County flood plain director Kirk Fuqua.

“He told us that he didn’t understand why the house was sold as not being in a flood plain when it had always been in the FEMA 100-year flood plain,” said Annette. Fuqua confirmed that information for Fort Worth Weekly and said his records showed no remedial action that would have removed the house from the flood plain.

“Not only that, but it turned out our house was built right on top of a drainage easement, a platted stream,” said Michael. The unnamed stream is a tributary of nearby Silver Creek.

Worse was coming. In 2008, a new FEMA study came out, again showing the Daniels’ house in the middle of a flood plain. As usual, FEMA alerted lenders, and three months after the first flash flood, Chase Home Mortgage Finance LLC, wrote to tell the Daniels they would need to acquire flood insurance.

The insurance added $500 a month to a steep mortgage that was already beginning to pinch, as the recession slowed the income from their travel business.

Unfortunately, the couple soon discovered that the Parker County appraiser had reduced the appraised value of their home to zero after the new FEMA study, and you can’t refinance a house valued at zero. Their land dropped in value from $75,000 to $25,000.

“So we owed $300,000 on a house that was valued at zero,” said Annette. “And with business slowing down we couldn’t even get at our equity. Who could have dreamt this was going to happen?”

Speaking of water...

A letter to the editor in the Fort Worth Star-Telegram makes another interesting point.  Protecting from flooding and supplying water, isn't that a water district's job?  WHAT are they up to instead?  Ask them.

Water pipelines

I totally agree with Friday letter writer Harry Kelly's logic about a water pipeline to Texas. This exact topic has been raised repeatedly among my engineering friends.

Water pipelines flowing south to Texas and other parched areas could have prevented the recent flooding of farmland along the Mississippi River. Similar pipelines placed strategically in flood-prone areas could be part of a network of pipelines nationwide to relieve drought-stricken areas as well as create new water storage reservoirs. There is no reason why our government cannot see the logic of moving the excess water from one place and send it to another that desperately needs it. This would also create thousands of jobs to build and maintain the life saving network.
