Gated communities on HGTV

Posted on by

As someone who studies suburbs and housing, I admit enjoying watching people choose homes on HGTV on shows like House Hunters. I’ve noticed that one factor that occasionally influences the choice of homes is whether it is located in a gated community. A few thoughts about this topic, gated communities, which has attracted more attention from sociologists and planner in the last two decades:

1. On these shows, the gated communities often pop up in the South or West, particularly in Florida or California.

2. We rarely see any evidence of the gated community like the entryway to the neighborhood (a fake guardhouse or a real guardhouse?)  or a fence around the entire neighborhood. We are simply told that the suburban home is in a gated community.

3.  At least when making their choices on screen, the people rarely talk much about the fact that a home is in a gated community. This is probably due to the fact that the show is supposed to be about the home and not the neighborhood. (So how about a new show where it is less about the individual housing unit and more about selecting a neighborhood?)

4. The homes in the gated communities vs. those that are not in a gated community look very similar. Ultimately, it is really rare that anyone on this show is selecting a home that is in a “unsafe neighborhood.” As sociologists have suggested, living in a gated community is often a decision made regarding some amorphous outside threat. They are devices that portray a certain image while also acting as reassurance for residents. As some have shown, like Setha Low in Behind the Gates, some suburban residents feel very afraid even when they live in exclusive, upscale neighborhoods. The gates in many neighborhoods don’t really keep people out but they help the residents feel better.

What to do when development projects, such as HSR, encounter opposition from residents

Posted on by

This is a common story: a developer, community, or a set of politicians put forth plans for a new development. Some residents or citizens complain that the project will negatively affect them. What is to be done to balance out their concerns versus the plans that have been made? How do we balance the rights of the individual versus the needs of the community?

This is taking place currently in California as state officials continue to move forward with plans for high-speed rail (HSR). According to The Infrastructurist, there are several fronts for complaints: one community suggests the high-speed rail will alter the character of their community and farmers are unhappy that some of their land will split by the tracks.

Within this debate, several themes emerge:

1. A longer and/or bigger view helps provide perspective. In the California case, the start of HSR in the Central Valley looks like a boondoggle because it doesn’t yet connect the largest cities in the state. But it is the start of a network that will expand and eventually provide 2.5 hour travel from San Francisco to LA.

1a. This might help: show that the funding for the later stages in the project, where the Central Valley start is connected at both ends to larger cities, is guaranteed. Otherwise, there might be some worry that this first part will get built and the later funding will dry up or disappear.

2. The time for debate about whether HSR rail is good or appropriate for California is over – it is going forward, particularly since there are Federal dollars committed to this. Yes, these farmers and communities may be affected but they are not going to be able to stop the whole project (unless, perhaps, they get a whole lot more people on their side).

3. The key for those promoting HSR is that they need to continue to focus on the benefits that will come. Some of this is through city revitalization as the HSR serves as a new economic engine. More broadly, it will benefit the state in terms of reducing traffic, provide a quicker form of transportation that flying, and be greener. Yes, people will complain that these are just guesses but then the promoters need to follow through and ensure that HSR actually does benefit the state.

4. Change is not easy. Even if all Californians agreed that HSR was good and it should be pursued, there are always issues regarding making it happen. This is a long-term project that will affect a number of people. The hope is that in the end, it will lead to more good than harm.

Places that might be deserted due to a lack of homebuyers

Posted on by

The issue (amongst many) in the ongoing economic malaise is a lack of homebuyers. To have a hot housing market, such as happened in much of the 1990s and some of the 2000s, you need both sellers and buyers. What happens if this temporary trend of a lack of buyers turns into something less than temporary?

One suggestion is that certain areas will be deserted:

Many economists argue that the housing market may take four or five years to recover. Even if that’s proven to be true, the all-time highs of 2006 may never be reached again.

The devastation in some regions will never be repaired. Parts of Oregon, Georgia and Arizona have become progressively more deserted. Since jobless rates may never recover, there is little reason to hope that the populations in these areas will ever rebound. Some homes will be torn down in these pockets of high foreclosures in the hopes that reducing supplies will boost prices. Whether that idea will work in hard-hit areas such as Flint, Mich., and Yuma, Ariz., remains to be seen.

If this comes to pass, this would be an interesting period in American history. Yes, we do have some instances of population loss: the “ghost towns” of the Old West come to mind as people poured into a region and then seemed to leave just as suddenly. Rust Belt cities like Detroit and Buffalo and Pittsburgh have been experiencing a slow but steady population drain over the last few decades. And I have tried to find evidence of “lost suburbs” – places that would go against the typical narrative of American suburbs continuing to grow in population and sprawl further out from cities.

But this prediction suggests that certain metropolitan regions might not have any hope of recovery. While some of these are Rust Belt places that already had issues (like Flint), others are newer, particularly locations Nevada, Arizona, and California. As a matter of public policy, what should be done? Should we prop up locations with government aid? Should we write certain areas off and let them slowly lose population until the critical population mass is gone? Is contraction worthwhile (something that has been debated now for several years regarding Detroit) or is simply losing a city or region a better option?

In the long run, the only possible solution seems to be to convince people that these areas are desirable places to live. One selling point, and this seems to come up a lot on the front page of Yahoo, is that these places have affordable housing. This may be the case but that won’t be enough to attract people – these areas need jobs, economic engines that will bring stability and profits to hard-hit regions. And which companies might be willing to step up?

Interestingly, Illinois ranks #5 on this list. It looks like this analysis says the main factors are a limited population growth and a severe loss in manufacturing jobs over the recent decades. Certain areas of the Chicago region seem more immune to this than others. DuPage County is populous and wealthy, partly due to the influx of higher-end, technology-related jobs that have entered the county since the 1960s. Because of this, DuPage County has an unemployment rate always multiple points below the national average.

Risk of California superstorm – and what should be done about it?

Posted on by

Human beings have a remarkable capacity to build settlements in harsh conditions. Recently, I have wondered what would possess settlers in the 1800s to live in the Upper Midwest with its harsh winters. A classic example of a place with both advantages and disadvantages: California. On one hand, a temperate to warm climate with a wonderful range of habitats (mountains to coast) and rich farmland in the middle of the state.

And yet, California has a number of natural threats. The latest: scientists predicting a superstorm that could flood the state for an extended period.

A group of more than 100 scientists and experts say in a new report that California faces the risk of a massive “superstorm” that could flood a quarter of the state’s homes and cause $300 billion to $400 billion in damage. Researchers point out that the potential scale of destruction in this storm scenario is four or five times the amount of damage that could be wrought by a major earthquake…

The threat of a cataclysmic California storm has been dormant for the past 150 years. Geological Survey director Marcia K. McNutt told the New York Times that a 300-mile stretch of the Central Valley was inundated from 1861-62. The floods were so bad that the state capital had to be moved to San Francisco, and Governor Leland Stanford had to take a rowboat to his own inauguration, the report notes. Even larger storms happened in past centuries, over the dates 212, 440, 603, 1029, 1418, and 1605, according to geological evidence…

The scientists built a model that showed a storm could last for more than 40 days and dump 10 feet of water on the state. The storm would be goaded on by an “atmospheric river” that would move water “at the same rate as 50 Mississippis discharging water into the Gulf of Mexico,” according to the AP. Winds could reach 125 miles per hour, and landslides could compound the damage, the report notes.

Such a superstorm is hypothetical but not improbable, climate researchers warn. “We think this event happens once every 100 or 200 years or so, which puts it in the same category as our big San Andreas earthquakes,” Geological Survey scientist Lucy Jones said in a press release.

If this is a real possibility, the question then becomes what the state should do about it. It is another example of weighting risks: should the state implement all sorts of rules and plans to limit the possible damage or should they simply go on with life and deal with the consequences when they come? Of course, California isn’t the only place that faces such questions: hurricanes pose a similar threat on the East or Gulf Coasts and many communities have homes or businesses built on flood plains.

Regardless of what California does with this information, perhaps this can become additional fodder for disaster movies. I can see the plot line now: California is hit with a major storm followed by a major earthquake with both accompanied with major mudslides followed by our set of heroes running for the hills…you’ve seen this plot line before. But this flood of 1861-1862 does sound intriguing – perhaps more information about this past event would help current officials plan for future events.

Finding the right model to predict crime in Santa Cruz

Posted on by

Science fiction stories are usually the setting when people talk about predicting crimes. But it appears that the police department in Santa Cruz is working with an academic in order to forecast where crimes will take place:

Santa Cruz police could be the first department in Northern California that will deploy officers based on forecasting.

Santa Clara University assistant math professor Dr. George Mohler said the same algorithms used to predict aftershocks from earthquakes work to predict crime.”We started with theories from sociological and criminological fields of research that says offenders are more likely to return to a place where they’ve been successful in the past,” Mohler said.

To test his theory, Mohler plugged in several years worth of old burglary data from Los Angeles. When a burglary is reported, Mohler’s model tells police where and when a so-called “after crime” is likely to occur.

The Santa Cruz Police Department has turned over 10 years of crime data to Mohler to run in the model.

I wonder if we will be able to read about the outcome of this trial, regardless of whether the outcome is good or bad. If the outcome is bad, perhaps the police department or the academic would not want to publicize the results.

On one hand, this simply seems to be a problem of getting enough data to make accurate enough predictions. On the other hand, there will always be some error in the predictions. For example, how could a model predict something like what happened in Arizona this past weekend? Of course, one could include some random noise into the model – but these random guesses could easily be wrong.

And knowing the location of where crime would happen doesn’t necessarily mean that the crime could be prevented.

The statistical calculations used for counting votes

Posted on by

Some might be surprised to hear that “Counting lots of ballots [in elections] with absolute precision is impossible.” Wired takes a brief look at how the vote totals are calculated:

Most laws leave the determination of the recount threshold to the discretion of registrars. But not California—at least not since earlier this year, when the state assembly passed a bill piloting a new method to make sure the vote isn’t rocking a little too hard. The formula comes from UC Berkeley statistician Philip Stark; he uses the error rate from audited precincts to calculate a key statistical number called the P-value. Election auditors already calculate the number of errors in any given precinct; the P-value helps them determine whether that error rate means the results are wrong. A low P-value means everything is copacetic: The purported winner is probably the one who indeed got the most votes. If you get a high value? Maybe hold off on those balloon drops.

A p-value is a key measure in most statistical analysis – it provides a measure of how much error is in the data and whether the obtained results are just by chance or whether we can be fairly sure (95% or more) the statistical estimation represents the whole population.

So what is the acceptable p-value for elections in California?

I would be curious to know whether people might seize upon this information for two reasons: (1) it shows the political system is not exact and therefore, possibly corrupt and (2) they distrust statistics altogether.

The zip codes with the most expensive real estate

Forbes put together a list of the American zip codes with the most expensive real estate. Of the top 10, 9 out of 10 are in California or New York City. (The lone outlier is a New Jersey zip code.)

During the final hours my wife and I had in California, we visited the Getty Center. In addition to the beautiful collection of art (and we only saw the European art) and the expansive views of the city and coast, the buildings and grounds are impressive. This is a view from the gardens looking toward some of the main buildings:

Mulholland Drive is a famous road that offers views of Los Angeles and the surrounding area. We spent nearly an hour driving along Mulholland Drive looking for a clear view of the city. We finally found a small spot to pull-off and snap this picture:

This street on the ridge to the north of Los Angeles is home to many wealthy people. See the road in this YouTube clip.

The view of the sunset from the pier at Pismo Beach, California. The town is a fairly small beach town and the pier seemed to be the local hang-out spot for many teenagers, some families, and a few surfers.
