The Population Vacuum

The Population Vacuum is a method by which major metro areas maintain affordability, efficiency at high population, and high living standards to “vacuum” up surrounding population growth. This limits urban sprawl and confines greater and greater numbers into as small an area as is feasible.

Requirements:

• Living must be affordable. A frequent reason for urban sprawl is the availability of large housing at prices that are in line with the average person OUTSIDE of already developed areas. Thus, people either in search of starter mansions or those merely in need of expanded housing for a new family have great incentives to look into virgin land. By ensuring large amounts of affordable, large housing in cities, and then making those cities eminently attractive, a metro area can act as a vacuum and attract those people and even cause a reduction in extant areas of sprawl.

• A city must be eminently attractive. It must match non-urban areas in as many aspects of attractiveness as it can. This will result in fewer people being driven to small towns. A drop in overall property taxes would result, but that should be offset with room to spare by taxes from the increased economic activity resulting from such population density. Areas to match as follows.

o Crime: A city must work hard to keep crime rates low. This does not mean more cops, it means better efficiency overall and finely targeted laws to reduce inefficiencies.

o Availability of nature: A city must not just have parks, it must be tightly integrated with parks. Gardens must be built into the overall design of buildings, blocks, and sections of the city. A 5/1 ratio of urban area to garden area is a target.

o Lack of pollution: Pollution must be a primary concern for city leaders. It must be kept under control at almost any cost.

o Elbow room: The design of the city must allow for “movement space,” or space in which an individual can move about without bumping into other people. This obviously applies to house size, but it must also be integrated into the side of streets, sidewalks, and general city layout. Sidewalks need not be actual sidewalks, but merely walkways that traverse the city. In a city of 10 million, walkways of 100 feet wide or more would be ideal.

o Noise: Perhaps the hardest area to match, noise must be kept under control without squelching the vibrancy of the city throughout the day and night. This could be achieved through heavy construction of underground roadways, walkways, and buildings. Separate the living areas from the noise-generating aspects of the city, the major perpetrator being traffic.

o Ease of automotive movement: Complex integration of major roadways and smaller transit lines to reduce the stop & go of city driving. Eliminate stop lights and intersections in favor of ramps and rotaries.
The city must also highlight, expand, and nurture the many aspects of a city that rural areas cannot match. These are as follows.

o 24/7: A city of sufficient population can remain active 24 hours per day. This allows for restaurants, entertainment, and destinations at any time. A city must foment this sort of behavior and stimulate activity at all times.

o Variety: A city is a complex mess of things. A city must encourage this variety and diversity through aggressive immigration campaigns from other cultures, encouragement of small business, and facilitation of mixing between areas of the city and different groups.

o Support: A strong system of governmental support is possible within a condensed population. Transportation, medicine, education, and economic support are all superior to rural areas.


Ideal Sufficiency: A city must strive to be self sufficient in as many ways as possible. This increases efficiency by streamlining supply routes and reducing travel times. Prime candidates for self-sufficient industry are agriculture through gardens and hydroponics, and power through solar, wind, and if coastal, tidal power generation. Nuclear power is also a viable option but less ideal than the totally non-polluting forms.

Over-stimulation: A city must have areas of quiet rest. Less-populated areas of the city without major structures with a substantially smaller degree of stimulation.

Under-capacity: A city must always keep its population under the capacity of the city’s infrastructure. If it doesn’t the vacuum will suck up surrounding populations, pressurize them, and then eject them back into rural areas and actually encourage urban sprawl. If the population exceeds capacity *cough*LONDON*cough*, all of the previously listed things that make rural areas attractive will deteriorate within the city and efficiency will dive.

Urban Sprawl

I recently purchased a book. Actually, that's a rather rare event for me. What with the infinite resource of the internet and a total disinterest in fiction, I spend almost no time in book stores anymore. Barnes & Noble has cheesecake to die for, though.

I picked up a book that I can safely say is worth the $20 it cost me. It's called A Field Guide to Sprawl. It is not directly anti-development, but it places images in front of you that can only lead to one conclusion; we're screwing up our planet in spectacular fashion.

The general point of the book is to define urban and rural developmental phenomena. They define well-known terms, like "Big Box Retailer" and a few less-known words, like "Boomburg" and "Starter Castle." You can guess what they mean, for the definitions make little difference to my point.

What the photos drive home is how devastating the current, unchecked, low-density expansion is to the planet and to the overall "nice" factor of our home. We go into an area, overpopulate it, destroy it, then the rich people leave, the poor people are left behind, we have a ghetto, and then we get the eventual sprawl of rich people ever outward, looking to get away from the horrid mess they left behind.

None of this is new. Conservationists and their ilk have been talking about this for the past 50 years. Pretty much since the dawn of Levittown, this has been seen. What I think is changing is that now, as opposed to even as little as twenty years ago, the effects of this sprawl are now very visible. The damage is real, as opposed to way off in the future.

I ranted and raved about yuppies and an earlier post. I hate them. Their unchecked expansion and total stupidity is, as I see it, the most destructive force in America. Materialism, the American Dream, and a population that's becoming ever more delineated economically all fuel the expansion of America outwardly. None of these things are inherently bad, it must be noted. Materialism is a totally valid way of life, drives the economy, and is the only reason 90% of the companies in existence, um, exist. The American dream is a great dream and should be striven for. And an economically delineated population is fine just so long as there is constant economic activity between the groups. But combined, along with the human penchant for thinking about "now" as opposed to "tomorrow," means that people will happily bulldoze trees, and Chem-Lawn the fuck out of their grass if it means being happy now.

We aren't there yet. The world is not coming to and end, but in 2007, the 300 millionth American was born, the 400 millionth will be born sometime mid century, and by 2100 we'll be well past half a billion. All this while household sizes are at record lows. The growth is logarithmic, the worse it gets, the worse the getting worse gets. Within just one lifetime, we'll more than double our population. The US can NOT survive with current demographic distribution and a population of 600 million, or perhaps 1 billion. Eventually, we'll have giant megalopoli covering the entire landmass of the US like some sickened pestilence. Then there will be nowhere left to which the yuppies can escape. No new, virgin land they can bulldoze. It will all be done, and then what?

As I said, the world is not ending. Things are, in reality, pretty good. But we must begin taking action now, or the damage in the future may be too great to repair. Especially now, taking action can be pretty cheap. The government can heavily restrict development on virgin land. In my opinion, there are many areas of the country where development on virgin land should be halted entirely. Then, give developers subsidies and tax breaks for building up instead of out.

Population growth is not bad. In fact, I think it's great. If we are to achieve the wondrous, interplanetary civilization that sci-fi has foretold we actually need more people. It's the unchecked outward, low-density growth that's bad. We spread like a bacteria when we should be building towards the heavens.

Ecopolis

In urban engineering, there's the concept of a bioligical city. The Discovery Channel ran a show called Ecopolis that touched on many of the ideas.

Fundamentally, the concept of a biological city comes from the ideal of a "living" city. Where the infrastructure we build is self-sustaining, to at least a degree. So that means plant life integrated with the design of the buildings and the urban layout; renewable energy in multiple forms; and a person-centric perspective on the layout of the city itself.

Discovery Channel chose Ecopolis because of the current green movement. The biggest concepts of the biological city have environmental friendliness as a result, but the vision is much larger than merely being ecologically sound. In fact, the perfect biological city would be something akin to an Arcology, just like the ones you could build in SimCity. Unfortunately, there are few who think arcologies are feasible in even the distant future. As such, engineering better cities as they are, now, is an achievable goal. It as close to an ideal city as we can manage, at least for now.

Detroit is the opposite of that ideal city. In this article from the Chicago Tribune, they put Detroit's problems into terrible focus. In it, they discuss the potential for Detroit to become America's city of the future, because everything is so bloody cheap. But being cheap isn't necessarily all that's needed. Because frequently, all that cheap attracts is the human detritus of society. Crime rates are high. Economic progress is low. Detroit itself needs a massive bailout.

But as the article points out,

"On a positive note, Detroit's homicide rate dropped 14 percent last year. That prompted mayoral candidate Stanley Christmas to tell the Detroit News recently, "I don't mean to be sarcastic, but there just isn't anyone left to kill."

At least he's honest.
