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.”

Staten Island – the ultimate in recovery problems

The Samuel I. Newhouse, one of two Barberi cla...

 

A compelling article from the HuffPost on Dec. 6th.: Staten Island’s Hurricane Sandy Damage Sheds Light on Complicated Political Battle.  For those who are not familiar with the many factors that affect recovery, be sure to read this article. It is 9 pages long, but a must read.

Staten Island after H.Sandy bears more resemblance to the 9th Ward of New Orleans after H. Katrina than you might have imagined.

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.

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

Annotated image of the confluence of the Missi...

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.

Buyouts after a disaster — may be the most cost-effective recovery option

From a book review in BusinessWeek.com, March 17, a Harvard economist looks at urban life in the future: Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Healthier and Happier, by Edward Glaeser.Penguin Press; 352 pp; $29.95.  Athough the book is primarily about urban planning, one quote from the review is worth considering:

The author’s prescription for Detroit, as well as Buffalo and Leipzig, is to “shrink to greatness” by searching for fresh advantages. What if they fail? Well, that would be too bad, but Glaeser believes cities are about people, not places or buildings. Does it make economic sense to resurrect Detroit when the cost of building a house is greater than the reward from selling it? It could have been cheaper, he notes, to hand every household in New Orleans $200,000 after Hurricane Katrina rather than pump vast quantities of public money into rebuilding a city of waning economic significance. As disturbing as this may sound for New Orleanians, there exists a far more disturbing thought: Glaeser may be right. As the latest U.S. Census figures prove, the city’s capital is disappearing in droves.

Flooding in Australia-catastrophic impacts

January 5: Catastrophic impacts on infrastructure are reported; see Reuters Account. According to BBC TV this evening they estimate more than 1 million sq. kilometers are affected!

On January 4th: Crocodiles, snakes are danger in flooded Australia.

ROCKHAMPTON, Australia – Residents of an Australian city cut off by some of the country’s worst flooding in decades are being warned to stay out of the water, and not just because of the risk of being swept away: Debris, snakes and even crocodiles could also pose a danger.

Large parts of the coastal city of Rockhampton were under water Tuesday. The waters were still rising, with the 75,000-strong population bracing for the floods’ expected peak in the next 24 hours as a huge inland sea spawned by heavy rain across Queensland state drains toward the ocean.

Australia Floods; BBC, Dec. 31. In this article, the author notes an interesting sequence for consideration during recovery. The economic losses are paramount in his mind, rather than community reconstruction.  This sequence also is seen in resort communities, especially in countries with mild weather so citizens can be sheltered outdoors.

I think that the least of our worry is the damage to small communities. Communities get rebuilt.

These floods are going to affect the state, the whole nation. It’s going to have a huge impact on mining commodities – several coal mines are under water and some won’t be operational for months.

There’ll be coal shortage and our ability to produce electricity will be affected. Certainly it will be an interesting start of the year and of the decade.”

“…the shows utilize the skills of volunteers with the PRCS gender programme. The young, energetic university students are responsible for developing programme content and lining up guests. “These shows are allowing us to communicate directly with flood-affected communities,” says 24 year old Sadia Jamil. “By providing a platform for them to voice their concerns, we can help find the best solution to resolve their problems.”

Pakistan Floods – preview of catastrophies to come and analysis of inadequate response system

Confronting Climate Displacement: Learning from Pakistan’s Floods. Relief Web.int; Nov. 22. From the Executive Summary. [Note that a link to the full text is provided in the article.]

In July 2010, massive rain in Pakistan led to unprecedented flooding that submerged one-fifth of the country and affected more than 20 million people. While many experts believe the floods were the result of climate change, others say the science is uncertain. Regardless, most agree that natural disasters are occurring more frequently and that the international community is ill-equipped to respond. It is estimated that by 2050, as many as 200 million people will be displaced by natural disasters and climate change. The world’s poorest and most crisis-prone countries will be disproportionately affected.

The Catastrophic Flooding in Pakistan – extent still not clear

Although the flooding has gone on for weeks, somehow the full scale and impact of the catastrophic flooding has not been effectively communicated to the world at large.See Death toll rises from Pakistan flooding, CNN, August 16. In actuality, the numbers of people affected are staggering and the response and recovery are hampered by the continuing flooding.  Some key facts:

  • The death toll from flooding that has ravaged Pakistan for more than two weeks is up to 1,463;
  • More than 895,200 houses have been damaged, and more than 2,000 people have been injured;
  • One-fifth of the country is under water. Roughly 900,000 are homeless as a result of the catastrophe
  • Thousands of towns and villages (estimated at 4,000) have been washed away.
  • U.N. Secretary-General Ban Ki-moon said …that while he has visited sites of natural disasters around the world, he has never seen anything like the devastation created by flooding in Pakistan.
  • He said the disaster is worse than the 2004 Indian Ocean tsunami and the 2005 Pakistani earthquake combined.

A thoughtful and comprehensive look at the longer-term impacts, including the stability of the country are examined in this NYTimes article: Floods Could Have Lasting Impact for Pakistan. N.Y. Times. If in fact this flood disaster is greater than the two most recent Asian catastrophic disasters noted above, are the capabilities of the international community sufficient to effectively assist? Add to that concern the political importance of Pakistan to the U.S.  This is a catastrophic disaster that bears careful watching.
