Disaster Planning

As many of you know, the nation of Haiti is facing a horrendous natural disaster of historic proportions. The current crisis of finding survivors, creating infirmaries, finding food, water and housing the displaced will be ongoing crisis for the next couple of weeks.

While I most certainly send my sincerest hopes and prayers that Haiti can overcome their most immediate crisis as quickly as possible, I wonder about what will be the fate of Port Au Prince, one year from now, five years from now and ten years from now. There are a lot places around the globe that have been impacted by natural disasters and have chosen not to rebuild because of the staggering costs of repairs. More recently, the location of development that are prone for natural disasters has come into question, leaving many government officials and the public wondering if the development should be rebuilt at all.

Haiti does not have that option. Even though the infrastructure to their capital has been destroyed they do not have the option of abandonment. Port Au Prince was not only the capital but also the hub of government services for the entire nation. Port Au Prince was also Haiti’s largest city that made it the commercial, industrial and social hub of the nation as well. The city has to be rebuilt…but how?

The city will need planners to come up with an immediate disaster plan along with a new Master Plan for rebuilding and growth for the future. Part of the reason why this disaster is so catastrophic is that there was no Master Plan in the city to begin with and growth occurred anywhere and everywhere haphazardly. Now whether a city with a weak central government can enforce that Master Plan is another story. However there are more than a few cities in developing plan that have been able to control growth and development through a Master Plan. And right now, Port Au Prince does not have a choice, in order to save the future of the city and perhaps the nation, a Master Plan is needed to sort out the chaos and shock of a complete government breakdown and destruction.

The immediate concerns are that the city needs everything right now. But when the immediate crisis is over, be it months or years from now there will have to be a plan on what, when and how the city will be rebuilt. There is no functional starting point to build off of right now in Port Au Prince. Do you rebuild housing first to shelter a city where all the residents have been displaced. Or do you focus on rebuilding stores since there is nowhere for people to buy food, clothing or cleaning supplies. Or do you rebuild the hospitals first? And in what order do you rebuild government buildings, schools and job sectors? All of these questions must be in accordance of a disaster plan and a future Master Plan.

The city cannot be rebuilt all at once. There are certain segments of the city that planners and residents are going to have to choose to rebuild first. The city will have to be rebuilt at a segment at a time, block-by-block, neighborhood-by-neighborhood at a time in accordance to a plan. If the city rebuilds in a piecemeal fashion then there will be properties in the city that will be left as unstable rubble for years and decades by property owners who cannot afford to rebuild or have gone missing.


There will also be some hard questions that planners and residents of the city will have to face in rebuilding the city. There is going to be questions of whether a city on a major fault line should be rebuilt. Because of that question, the city cannot rebuild in the same pattern and function as it did before the earthquake. While many who rebuild may not be able to have expensive earthquake retrofitted buildings like in Los Angeles and Tokyo, new building standards can be set in place to reinforce concrete construction with steel. If this cannot be done for all construction it should at least occur in major government institutions, hospitals and schools.

Other questions the city will have to face is whether construction should be allowed on the hill tops closest to the fault line. Housing construction on the hill and mountaintops would not only be a potential hazard it has also contributed to deforestation, which has also contributed to massive flooding. The placement of the city’s transportation infrastructure may have to relocate. While the airport only received moderate damage, the blockages to this vital transportation hub has made it almost impossible to deliver resources to the rest of the city. These ports in the future will need to be isolated and not located in the heart of the city. Lastly, what will the city do with the tons of crushed concrete slabs? What took generations to build by piecemeal will not have to be cleared in a massive fashion.


All of these questions are all apart of major disaster planning and city master planning that has to be addressed soon. Without a plan on how to redevelop the city’s current plight and its future reconstruction, the city will not be able to recover by piecemeal construction.

Informal Cities

Swiped from the Africa Unchained blog:

An excerpt from Robert Neuwirth's Lecture 'The Extroverted City of System D' a contribution to the book Open City:

In Lagos, everything is informal. The bus system is informal—the government got out of mass transit business decades ago (though it has recently stepped back into public transport with a bus rapid transit line) and the system that includes more than 75,000 danfos was held together informally by the National Union of Road Transport Workers as one-part mass transit and one-part Ponzi scheme. One of the largest formal supermarkets in Lagos buys most of its product from informal wholesalers. Some major multinationals here distribute their products through informal networks. And informal merchants invest in the formal world.

Authorities in the city acknowledge that as much as 80 percent of the work force—and Lagos has between nine and 17 million inhabitants, depending on where you draw the boundaries and who’s doing the counting—is involved in the informal sector. The federal government also suggests that somewhere around 60 to 70 percent of the country’s economic activity derives in some way from the informal sector—and this means that, in aggregate, merchants like Prince Chidi Onyeyirim and Fatai Agbalaya are more important to Nigeria’s future than Shell, Mobil, and Chevron, the multinational oil giants that pump sweet crude from the Niger River Delta.

As Mega-Cities continue to explode in population around the world (particularly in Africa) they continue to stretch the conceptual frameworks of what cities were meant to be and how they are organized. Most modern cities may appear to chaotic but when examined closely, they are heavily structured and organized systems that control and dictate the flow of traffic, development, water, sewage, air and open space. The lack of those uniform structural systems in dense urban places creates chaos and challenges the belief of whether that urban place is truly a defined city jurisdiction with a definitive boundaries to the city's power of influence and control. The uninformed mega-cities of today have no beginnings and endings to the jurisdiction's scope of power.

Planning and the White City

As many city planners and urban historians know, the 1893 World’s Fair in Chicago greatly influenced how city officials at the time could envision cities. See the fair included a futuristic expo about cities, which included human scale models of grand institutional buildings set alongside broad tree-lined boulevards and intricately laid out parks that incorporated the best of the city and nature. The expo laid the foundation for creating this nation’s first city Master Plan. The expo would forever change how America looked at its cities, which at the time were crowded, dreary places that lacked open space, clean air and parks for recreational activities. The very progressive and socially liberal expo of the 1893 World’s Fair was dubbed the White City after the color of all the monumental buildings that were constructed. Planners and cityophile geeks are probably familiar with the book and documentary, Magic and the White City, which covered the creation and influence of the 1893 expo.

Over one hundred years later, we have a knew version of the White City which is just as progressive and liberal as the 1893 expo was at it’s time. These meticulously planned cities are also very progressive and liberal and have a heavy emphasis on connecting the urban form with nature. These cities, which pride themselves on creating cities with a human scale, have been dubbed White Cities not because of the color of their buildings but because of the lack of color in their city’s population. Newsgeography.com recently ran an article called
The White City, lamenting the fact that many of the cities that have been dubbed as progressive or even cool among national planning pundits and observers are almost entirely white. The article states:

Among the media, academia and within planning circles, there’s a generally standing answer to the question of what cities are the best, the most progressive and best role models for small and mid-sized cities. The standard list includes Portland, Seattle, Austin, Minneapolis, and Denver. In particular, Portland is held up as a paradigm, with its urban growth boundary, extensive transit system, excellent cycling culture, and a pro-density policy. These cities are frequently contrasted with those of the Rust Belt and South, which are found wanting, often even by locals, as 'cool' urban places.

But look closely at these exemplars and a curious fact emerges. If you take away the dominant Tier One cities like New York, Chicago and Los Angeles you will find that the “progressive” cities aren’t red or blue, but another color entirely: white.”

The article continues on to question how can cities be labeled as hip and progressive if they lack a diversity of cultures. The author wonders out loud whether there is a correlation between what is labeled a progressive city and a lack of diversity within that city. And if that is so, what does that really say about those who consider themselves liberal? The author does acknowledge that having a homogeneous population allows cities to pass major government planning expenditures like transit with much more considerable ease because there are no competing interests, threatened communities or communities that would receive more benefits then others. While, without a doubt, planning for the diverse needs of multiple incomes, cultures and beliefs definitely makes planning for the whole a lot more difficult, the author does not let “progressive” cities off the hook for not reaching out to their small but present black communities. The article goes on to state:

I believe that cities that start taking their African American and other minority communities seriously, seeing them as a pillar of civic growth, will reap big dividends and distinguish themselves in the marketplace.

This trail has been blazed not by the 'progressive' paragons but by places like Atlanta, Dallas and Houston. Atlanta, long known as one of America's premier African American cities, has boomed to become the capital of the New South. It should come as no surprise that good for African Americans has meant good for whites too.”

To that specific point, social commentator and essayist
Ta-Nehisi Coates wrote on his blog that:

“...leaving aside the blinding whiteness of dubbing Atlanta "un-progressive," leaving aside that most of these "progressive" cities have more black people than their surrounding states, I think the implicit argument that these cities should be "doing more" to assure that their black population meets the national average is odious.

Man listen--Negroes like Atlanta. Negroes like Chicago. Negroes like Houston. Negroes like Raleigh-Durham (another area that doesn't make the cut, for some reason.) Negroes like Oakland. Negroes have the right to like where they live, independent of Massa, for their own particular, native, independent reasons (family? great barbecue? housing stock?) Just like Jewish-Americans have the right to like New York--or not. Just like Japanese-Americans have the right to like Cali--or not.”

I think Ta-Nehisi makes a great point. There are going to be cities that certain cities gravitate too for many reasons. Just because a city lacks diversity does not mean that they should pump up the city’s community of color just for the sake of being more diverse. True diversity will come to a city naturally and most importantly, internally as long as that city is open to everyone and is not discriminatory. Now if we find out that these “progressive” cities are really inhospitable to certain cultures or they try to minimize the size of a different culture (the old planning text adage is that when the minority population increases over 10% of the population, white flight starts to occur). If these cities are truly progressive and they still lack diversity then it may just not be those communities cup of tea.

As a city planner, I do find it interesting that the cities and places with the largest black populations such as Atlanta, Houston, Charlotte and the D.C. suburbs are some of the most sprawling cities and locales in the country. We all know that obesity is a national problem and near epidemic levels in portions of the black community. While having a preeminent large upper and middle class community in these major cities is great sign of progress, are the locations of where of the large black middle class lives really doing more harm than good? And while the author of The White City is asking why are progressively planned cities so white, the question I would like to know is why the locations of the black middle class are planned so horribly?

What is your take on progressive white cities and their lack of diversity? Also what is your opinion on why cities with a large black population have so much sprawl? Do you see any correlations? I would like to hear your thoughts, please leave a comment.

Will Africa soon become an Urban Continent?

According to the Economist, maybe so...

"…Africa is still something of a demographic outlier compared with the rest of the developing world. Long berated (or loved) as the sleepiest continent, it has now become the fastest-growing and fastest-urbanising one. Its population has grown from 110m in 1850 to 1 billion today. Its fertility rate is still high: the average woman born today can expect to have five children in her child-bearing years, compared with just 1.7 in East Asia. Barring catastrophe, Africa’s population will reach 2 billion by 2050. To get a sense of this kind of increase, consider that in 1950 there were two Europeans for every African; by 2050, on present trends, there will be two Africans for every European (see chart 1).


One African in two is a child. The numbers are such that traditional ways of caring for children in extended families and communities are breaking down…


Africa’s rate of urbanisation is the fastest the world has ever seen, says Anna Tibaijuka, the head of Habitat, the UN agency responsible for urban development. In 1950 only Alexandria and Cairo exceeded 1m people. When the city rush is done, Africa may have 80 cities with more than 1m people, plus a cluster of megacities headed by Kinshasa, Lagos and Cairo—none of which show signs of mass starvation. Intermediary towns of 50,000-100,000 people will soak up most of those coming from the countryside. Urbanisation is part of the solution to Africa’s demographic problems, not a manifestation of them."

The biggest question I have is whether African cities will adopt city planning methods to strategically plan and control growth and not let new development grow haphazardly as seen in other developing nations. There are several urban locales in South and Southeast Asia that have dense populations of 1 million people or more but they hard to define as cities. They appear to be more of a collection of dense high rise developments or communities that all function independently of each other. The same can be said of many current African cities today. Hopefully small African cities now that are expected to explode in population can implement plans now before they become overrun with major developments.

Another question I have for anyone to answer is how will Africa becoming a more urban continent change your perception of the continent?

Detroit


I have never been to Detroit but I always have a fondness for cities like it because they will never be what they once were. I primarily grew up in Baltimore and spent a lot of time in Philadelphia so I understand what it feels like to see a city past it's glory years. No matter how much time as planners we spend to make our overall city environments better, we know that the factories that helped build our towns and cities and the factory workers who lived in them, are not coming back. The barren industrial landscapes are not only eyesores but they continue to decay into decrepit architectural skeletons.
.
While others mock Detroit's struggles or just write it off as a forgotten city, I have great sympathy for a city which helped create our modern way of life. A large part of who we are and how we define ourselves was built off of Detroit Labor and for that I don't feel it is right that we turn our back to the city now that it is struggling. I understand that we are a free market capitalist society and that industries come and go and it is up to cities to plan better for it's peaks and valleys. I am also certain that the city and state governments as well as the major car companies did not have a proper plan in place for the city's future and in those respects, the city was destined to fail. But ask yourself, on a historical level, where would we be as a country, without Detroit?
.
Detroit was a great American industrial jewel that we are allowing to crumble like the ruins in Rome. The only catch is that Detroit has not been deserted. Among these industrial ruins is the nation's 11th largest city where over 900,000 people reside. Our nation's forgotten major city is still larger then the cosmopolitan cities of San Fransisco, Boston, Seattle and Washington D.C. While we can never bring Detroit back to what it was 50 years ago, we can still transform the city from a once great industrial city into a great historical city and not watch city turn into a ruin from a far.









"Despite the ugliness that is inherent in these photos: the ugliness of poverty, the tragedy of loss, and waste, this building still lets us glimpse something beautiful. In Detroit this beauty is uniquely sustained. In other cities, buildings like this would be turned into luxury loft condominiums. They would be knocked down so that something new could be built in their place, their contents dragged off to a landfill and forgotten. Here we get to see what the world will look like when we're gone. We see that the world will indeed go on, and there is a certain beauty to nature's indifference."

"The Garden" Trailer

The Garden is the unflinching look at the struggle between urban farmers and the City of Los Angeles and a powerful developer who wants to evict them and build warehouses. Mostly immigrants from Latin American countries where they feared for their lives if they were to speak out, we watch them organize, fight back, and demand, "Where is our 'Justice for all'?"

Urbanizing Dallas

The City of Dallas and it's city planners are looking to introduce a formal zoning code to try to curb unregulated sprawl and to increase development in downtown neighborhoods. For those of you that are unfamiliar with Texas and their land use laws, you should that Texans are fiercely pro-property rights and are against any government regulation. So much so, that it is against the law for a planning official to label a zoning map an official government document. Texas zoning or land use maps or more recommendations.

What does this mean when it comes to city development? It means that anyone can subdivide their land almost as many times as they want and construct a development as large as they desire...anywhere. No matter the scale or appropriateness of that development. This means that a 70 story skyscraper can be placed outside of a downtown next to a freeway exit with no other large office development nearby (Houston, Tx).

So what is the big deal of allowing the market to determine development, the last thing we need in this economy is for government to stifle growth of businesses and construction, right? Well the problem is that these cities are inefficient and non-sustainable and actually cost tax payers more money to provide services to sprawling developments then it would it city developments were dense and compact. Wherever development goes, infrastructure has to follow. That means, highways, roads, bridges, power, water, schools, police, fire, ambulance all have to provided for large developments no matter how far or inconvenient. All of these services are expensive and they tax the residents of existing development even more to pay up front for services to another development that they will most likely never use.

Besides the monetary expenses of development there are other consequences in allowing sprawl. One of the most harmful consequences is pollution. Houston is now one of the country's most polluted cities because of smog. Texas cities are dependent on freeways for travel. In Dallas,the mere mention of a subway system brings out strong protest. Other factors, are quality of life factors and having those that normally dependent on public transit forced to seek automobile transit some how, some way.

Despite all of the negative consequences, there are Texas planners that vehemently oppose zoning and hold up their cities as a model of success purely on the fact that their cities continue to grow while East coast cities (the cities with zoning codes) continue to shrink. While it is true that East coast zoning codes have become burdensome encyclopedia of regulations, allowing the market to dictate development is even more troubling. Remember parts of the code exist because the market had no problem cramming workers into dumbell tenement housing that lacked air, light, sewer and trash disposal.

In Dallas, the continued pattern of suburban growth and increased population has planners looking for better solutions. While Dallas planners are still not in favor of traditional zoning, which is based on prohibiting land uses, they are looking toward the new urbanist approach of "Form Based Zoning" which promotes land uses on coded streets that a community would to see. From a
recent article:

"The solution most proposed was 'form-based zoning,' which encourages developers to purchase large tracts of land on which to develop dense urban areas near transit stations and along the Trinity River.

It’s kind of like college vs. the real world. In college, parties just sort of happen. As adults, parties come with the cumbersome trappings of invitations and phone calls, dates, times and places to meet up.

In districts with the proposed zoning ordinances, Dallas-ites can live and have fun in the same vicinity: they spend an evening wandering around, stumble upon a new coffee shop, see a movie, find a nice place to sit and talk, have a beer, run into friends, and walk home in a single night."

Hopefully Dallas Planners can convince it's council to implement a new urban zoning code. And hopefully other cities not just in Texas but in suburban locales all across this county can do the same. In an country that is 80% urbanized we can no longer continue are pattern of sub-urban growth. As a country we can not afford the infrastructure and as of last summer, we could not afford the gas for our commute. Our post World War II development patterns can no longer continue, we must create a new pattern of development for a new generation of people that is sustainable and not over extend our local governments like a proverbial credit card as they bank on future growth which may not happen.

A City Made Of Waste - Second Hand Urbanism

This is a pretty amazing video of how waste from San Diego is recycled in neighboring Tijauna for housing and infastructure.

Returning Detroit Back to Nature


A recent AP article covered what I think is one of the most fascinating "urban renewal" projects occurring in Detroit right now, which is Urban Farming. With the city's population less than half of what it was in 1950 there are thousands of empty lots in Detroit that are being converted into mini-farms.

The AP article quotes:

"With enough abandoned lots to fill the city of San Francisco, Motown is 138 square miles divided between expanses of decay and emptiness and tracts of still-functioning communities and commercial areas. Six barren acres of an estimated 17,000 have already been turned into "mini-farms," demonstrating the lengths to which planners will go to make land productive."

To me the irony of Detroit, one of America's most industrialized cities where car production was revolutionised which created negative environmental conditions such as smog and helped cities decentralize only to be converted back into a farm is fitting. We have all seen the Disney Cartoon of the little house that eventually got surrounded by the big city but we have never seen the big city go into reverse. The only times we have seen big cities go in reverse are in a apocalyptic fantasies where nature consumes cities after the people have vanquished. But to see the people return the city into a farm has to be a new chapter in the history of city development. Could this be a new chapter in city planning history that the fate of all cities could face that somehow Detroit had fast forwarded through time to reach this eventual conclusion?

The last question posed is very interesting because while Detroit is one of the biggest cities in the rustbelt of the U.S. it is not alone in the declining population and property value of it's city. There are dozens of small towns and cities across Michigan, Ohio and Pennsylvania whose fates were dependent on industry which appears will never return. Can Detroit be a model of a new green city in the rustbelt? Can these industrial towns despite the decades worth of toxins in the ground actually produce a life sustaining farm? I was always told by planning professors that once farmland is developed that it can return back to farmland again - is Detroit proving that theory wrong?

What is your opinion?

Urban farming takes root in Detroit

This is pretty shocking, I might not have believed this story if were not for a youtube video a couple of years ago showing farmers and wildlife preserves in the middle of the city of Detroit!

I know things have gotten bad for the U.S. car capital but as a nation how do we allow a major city to fall into rumble like a not so ancient Roman ruin? While I'm glad they are using the land for something more prodcutive, I hope before they create anymore farms, that not one more development is planned on the fringes of the Deroit Metropolitan area and that infill development within city or at leat within it's beltway will be mandatory.

An Excerpt from the article:

...The idea is very simple: turn wasteland into free vegetable gardens and feed the poor people who live nearby.

...Providing free food on the doorstep brings people together and spreads collective wisdom, according to local city hall manager Gail Carr.

"Fresh fruits and vegetables are something that we all need. And we really, really need to educate our children in that area.

"If we don't, we're going to have a lost generation to many diseases such as diabetes," she said."
