Flood Mitigation Efforts in Other Countries

QUEENSLAND AUSTRALIA

The U.S. is not the only country trying to think ahead and find ways to mitigate future flood damage.  Queensland has experienced many devastating floods in recent years and is working to anticipate and aboid future flood damamges. Here are two sources of more information about their present efforts:

Good Example of Floodproofing High Rise Office Buildings

Bottom of Wall Street from

From the NY Times on Feb. 20, Landlords in NYC . An Interesting account of how owners of high-priced commercial office buildings have taken mitigation measures in light of future flooding.  If you have money and are smart enough to think ahead about the costs and benefits of mitigation, the high rises can be protected.

Earlier this month (Feb. 14), the posting dealt with the concerns of the mayor of  Hoboken, N.J. about how to assure flood migitation for high rise residential structures, for moderate income residents.

 

 

Floodproofing High Rise Buildings

Posted via email from hobokencondos's posterous

When a densely populated urban area contains mostly high rise dwellings, selecting mitigation measures to reduce future floods is a major challenge.  Here is one mayor’s approach: Hoboken Mayor Seeks Storm Protection More Suitable for High-Rise Buildings. Excerpts from the NY Time article on Feb. 12 follow:

The mayor of this city of 50,000 across the Hudson River from New York, badly damaged by the storm, is pushing federal and state officials to make it a test case for a new model of hurricane resilience, one that could be translated to other cities in the Northeast that rising seas have increasingly turned into flood plains.

Most bluntly, Mayor Dawn Zimmer said, that means accepting and planning for the likelihood that most residents will not evacuate, even under an official order. And it requires adjusting federal flood-insurance guidelines to recognize that it is not possible to elevate an entire city. About two-thirds of Hoboken lies in the flood zone on new federal maps, but apart from the rare single-family homes, most buildings are apartment complexes or attached houses that cannot easily be mounted on pilings.

“The rules don’t work,” Mayor Zimmer said. “They’re looking at a fairly suburban approach. We need to carve out an urban approach. Because today it’s Hoboken, tomorrow, Boston.”

NYC at Risk from Flooding and Sea Level Rise

English: Taken from "The Top of the Rock&...

Hurricane experts have known for decades that NYC is a vulnerable place. In fact H. Irene gave people in NYC a good scare. New article from Homeland Security Newswires provides some new details about the risk and vulnerability of the Big Apple: New York unprepared for flooding, sea level rise; 24 September 2012. The article starts with:

New York City may be a fast paced city of bright lights, sleek attitudes, fashion trends, and some of the best sports teams in the country, but underneath the glitz and glamour is a city which is not prepared for an act of God and which is being threatened by rising sea levels and severe storm flooding; “It’s a million small changes that need to happen,” one expert says

Catastrophic Flooding in Bangkok and elsewhere in Thailand

According to the latest CNN report, the flooding is affecting about 1/3 of the country.  The extent and the duration are extraordinary. See today’s report in CNN.

An interesting secondary effort is that the manufacturing interruptions in Thailand are causing economic problems for Japan.  Japan’s supply chain is once again affected, this time by a disaster outside of its national boundaries.  See this Wall St. Journal article on Oct. 27.

The Need for Realism in Recovery Planning

Proud city will recover is the title of an editorial in the Minot Daily News on June 26.  While I do not want to demean efforts to bolster the spirits of local residents and property owners in Minot, efforts that exhort readers to return may get in the way of individual decision-making to the contrary. Not every victim of a natural disaster may have the time, will, and money to return to a damaged property. Some may not want to return to the neighborhood or even the city after the disaster.  After all,  the Souris River will still be there, and a future flood remains a possibility.

A quote comes to mind here: “Nature to be commanded must be obeyed.” Source: Sir Francis Bacon.

Here is the article with one sentenced highlighted by me:

Swamped. Devastated. Inundated. Evacuated. Flooded.

All those words describe Minot during the past week, as the Souris River swept through the heart of the city. Homes destroyed. Businesses closed or destroyed. Thousands of residents displaced.

The situation went from dire to dangerous in a matter of days. In some cases, the river made dramatic, historic changes in a matter of minutes, swamping areas that were dry one minute, and were soaked the next minute.

The city of Minot will never be the same. It can’t be.

The residents will return, whether it be in days, weeks or months. They will return to destroyed homes and shattered lives. But we have no doubt that they will return. They are, after all, Minoters and North Dakotans.

Residents all along the river fought valiantly, including weeks of backbreaking sandbagging and diking. But in the end, the river simply overwhelmed everyone’s best efforts.

Thanks to fellow blogger, Phil Palen, for pointing out this article.

One more article on the topic of recovery in Minot appeared in the Deseret News ( Salt Lake City) on June 26.  The lack of flood insurance is a major factor in recovery decision making in Minot.

Flooding Along the Mississippi River – an update

May 8th:

  • Christian Science Monitor on the impending floods in Midwest. Dates and times are available for these pending disasters.
  • See article re the effects of the mitigation measures — opening the spillways — on fish, shellfish, and fishermen in the Gulf area.  What is really sad about the flooding is how is it adding the problems and damage recently experienced in states like LA, AL, and MI  — short a compounding effect from sequential disasters.

My Prediction: Huge Disaster Recovery Problems in U.S. during May

Annotated image of the confluence of the Missi...

Image via Wikipedia

I have never posted a prediction before, but it is not hard to anticipate that FEMA and many other agencies and organizations dealing with disaster recovery should expect a demanding workload in May.  Here are 3 reasons for this prediction:

Reason #1:  aftermath of  the tornadic outbreaks in 6 southern states, less than one week ago; we already have  seen  major damage to many thousands of residences/businesses/other structures. The damage assessments are not yet completed, but it is easy to anticipate major rehousing/and or relocation efforts will be necessary.  [Today’s Christian Science Monitor discusses the likelihood that the Tuscaloosa Tornado is an all-time record setter for size and impact.]

These tornadoes also present the first major challenge to FEMA under the Obama Administration. See the WashPost article today: Storm recovery a test for administration, April 30, 2011.  At a later date I am planning to cover some of the problems likely regarding the large numbers of low and moderate income housing units needed, and the problems of budget constraints at all levels of government. Note that Prof. Bill Waugh has touched on these issues already:

The enormity of a cleanup effort that spans eight states provides first major challenge for President Obama in responding to a natural disaster. Promising federal aid to help towns rebuild, he says, “We’re going to make sure you’re not forgotten.”

Rebuilding is going to be a real chore” for the federal government, said Bill Waugh, a professor at the University of Mississippi and an emergency management expert. FEMA will need to move quickly to find enough temporary housing for displaced survivors, he said. “These days, with the economy so bad, a lot of people have probably dropped their house insurance,” Waugh said. “So recouping the losses could be very difficult.”

Reason #2:  anticipated major flooding in the Mississippi Valley. Warnings are already being posted for major flooding in a number of states in the Mississippi and Ohio Valley areas.  A repeat flooding event poses significant problems, some of which can be anticipated from a record-setting previous event in 1927 and others will result from some states experiencing both disasters.  See Historic Flooding Unfolding Along Mississippi, Ohio Rivers, from Accuweather.com, April 29, 2011.

As if tornadoes and damaging thunderstorms were not enough, historic flooding is also threatening the Mississippi River, below St. Louis, as well as the lower part of the Ohio River. The rising waters are expected to top levels set during February 1937. This mark is the middle Mississippi Valley’s equivalent to the 1993 event farther north along Old Man River.

Even if rain were to fall at a normal rate for the remainder of the spring, the consequences of what has already happened in the Midwest will affect the way of life, property, agriculture and travel/shipping/navigation for weeks in the region.

While the amount of evacuees currently numbers in the hundreds, it could soon number in the tens of thousands as levees are topped or breached and rivers expand their girth into more farming communities, towns and cities.

Sadly, the response in 1927 included some truly awful racial discrimination; the arbitrary and inequitable aspects of the response and recovery presented great hardship to a number of victims.

Reason #3: FEMA is planning a major disaster exercise, in the New Madrid Earthquake Zone in early May.  This National Level Exercise will involve active “play” by several federal regions, several states, and a large no. of municipalities.  Some of those key actors will be dealing with the two actual events noted above.  If  FEMA Director, Craig Fugate, goes through with his plans to hold the exercise as scheduled, FEMA, and also state and local emergency management officials, will be extraordinarily busy with two real and one simulated large-to-catastrophic events.

Huge Economic and Financial Impacts of Australia Floods

Location of Queensland on Australia.

Australian treasurer: economic toll from flooding ‘will be enormous;” CNN;January 23. In his first economic note of 2011, Swan said “it’s still too early to quantify the impact with any certainty at this stage.” But he said there’s “no question that the economic impact of these floods will be enormous.” Swan said the floods have devastated crops, tourism, retail and manufacturing and have disrupted major urban areas like Brisbane.

“One of the biggest casualties is likely to be our coal exports, with many mines shut down in big coal mining regions like the Bowen Basin, and supply chains severely hampered…”
“While this will be partly offset by higher prices, the loss of production will be hit much harder.”
Swan said the government has already made about $227 million in disaster recovery payments to people who have been affected by the floods.
“Over the coming weeks, months and years, the Commonwealth Government will be investing billions of dollars to get Queensland back on its feet…”

New threat for CA – superfloods

If Quakes Weren’t Enough, Enter the ‘Superstorm.’ NY times. Jan. 15, 2011.

California faces the risk not just of devastating earthquakes but also of a catastrophic storm that could tear at the coasts, inundate the Central Valley and cause four to five times as much economic damage as a large quake, scientists and emergency planners warn.

The potential for such a storm was described at a conference of federal and California officials that ended Friday. Combining advanced flood mapping and atmospheric projections with data on California’s geologic flood history, over 100 scientists calculated the probable consequences of a “superstorm” carrying tropical moisture from the South Pacific and dropping up to 10 feet of rain across the state.

Some technical details from the US Geological Survey can be found here.
