Findings about mixed-use communities and crime rates

Mixed-use developments are the rage these days among architects and planners, both in urban and suburban settings. However, there is some contradictory research about whether these developments have higher or lower crime rates. One recent study suggests that crime is reduced once there are enough people on the streets even as there might be a short-term increase in crime before the neighborhood has enough people on the streets. An earlier study had suggested that mixed-use neighborhoods lead to higher levels of crime and therefore, planners should design neighborhoods with features to reduce crime.

This reminds me of Jane Jacob’s ideas of “eyes on the street.” Jacobs suggested this was easier to maintain in mixed-use urban neighborhoods where storekeepers, shoppers, residents and others maintained a steady watch on what happened in the neighborhood.

Looking at the educationally rich Washington D.C. metro area

Based on recently released figures from the 2009 American Community Survey, the Washington Post describes the Washington D.C. metropolitan area, the most educated region in the country:

The data, drawn from questionnaires, underscore the academic primacy of the Washington area: 47 percent of adults – or nearly 2 million – hold bachelor’s degrees, the highest rate among the nation’s large urban areas. Six of the 10 best-educated U.S. counties are within commuting distance of the District.

Half of all degrees in the region are in natural and social sciences, well above the national average, under a broad Census Bureau definition of “science” that includes everything from nuclear physics to sociology. That’s a starting point for looking at variations within the region: So-called hard sciences reign beyond the Beltway, soft ones within.

There are some other interesting facts in here as well, such as the finding that the proportion of people of business degrees in the region is lower than the national average.

What I would be interested to know is how these statistics change the day-to-day lived experience of an average resident of the region. Are there more civic events with more involvement from nearby residents? Is there a large perceived gap between the lives of those who are well educated and those with less education? Do people strike up deeper conversations at any gathering? Does this concentration of people lead to more interdisciplinary work and research?

Americans walk less than other countries

The Infrastructurist sums up some recent research that shows Americans walk less than residents of other countries. Explaining why this is the case is interesting:

The report’s lead author, David R. Bassett of the University of Tennessee, blames America’s poor performance on its auto obsession and lack of public transportation…

The researchers found no association between daily steps and living environment (e.g. urban, suburban, or rural)…

For the year 2009 alone, the top five walking commuter cities were Boston (14.1 percent commuted by foot), Washington (11.1), San Francisco (10.3), New York (10.3), and Philadelphia (8.7). The city with the lowest commuter walking share for the year was Fort Worth, at 1.2 percent. Freemark comments:

“As the chart shows, automobiles have a majority share in all cities except New York, Boston, Washington, and San Francisco. Unsurprisingly, these are dense cities and the places in the United States with the most complete transit systems.

These arguments make sense at face value: driving and setting would seem to play a large role. However, the first research study’s finding about driving may indicate that driving just trumps other factors for most Americans: whether Americans live in cities or suburbs or rural areas, driving is the preferred mode of transit.

Additionally, perhaps the number of people living in large cities with established and effective mass transit (the five top walking cities cited above) is simply not enough to counter all the drivers in other places.

Fighting “immappancy” by looking at the true size of Africa

Many people have skewed perceptions of the world due to maps. Americans are used to seeing the United States (and North America) as the focal point of their maps; woe to those who put eastern Asia as the main point or even the Southern Hemisphere as the right way up! (What is interesting in these cases is that it reduces the United States to more of an afterthought. This doesn’t fit American cultural perceptions of our ) Another issue is one of size: because of the typically used projections, Greenland can vary from the largest mass in the world to a small mass. Relative sizes can be difficult to judge.

To combat “immappancy” (which apparently is a mash-up of illiteracy and innumeracy), here is a graphic that shows the size of Africa. Notice how large it is: the contiguous United States, China, all of Europe, and India all fit inside it. Yet how many people would know the true size of Africa?

Tunnels as infrastructure and symbols of pride

Boring machines broke through today at the opposite end of a 35.4 mile tunnel in the Alps, creating the world’s longest tunnel in Switzerland and taking the title away from Japan. While this is a feat of engineering (allowing high speed trains to carry cargo under the mountains rather than have it be shipped on trucks over the Alps), it is also interesting to read about the emotional responses people are having:

Trumpets sounded, cheers reverberated and even burly workers wiped away tears as foreman Eduard Baer lifted a statue of Saint Barbara — the patron saint of miners — through a small hole in the enormous drilling machine thousands of feet (meters) underground in central Switzerland.

At that moment, a 35.4-mile (57-kilometer) tunnel was born, and the Alpine nation reclaimed the record from Japan’s Seikan Tunnel. Television stations across Europe showed the event live…

Peter Fueglistaler, director of the Swiss Federal Office of Transport, called Friday “a day of joy for Switzerland.”

“We are not a very emotional people but if we have the longest tunnel in the world, this also for us is very, very emotional” he told The Associated Press.

This project is not just a boon for business and the environment; it is seen as a testament to the will and determination of the Swiss. As a project that has been in the works for decades (with the referendum votes for funding taking place nearly two decades ago), to see the proverbial “light at the end of the tunnel” is a big accomplishment. This is cultural moment that will likely become part of the Swiss collective memory.

How might the response in the United States to such an engineering feat differ?

Planning for Los Angeles’ future

This video from CNN takes a look at some thinking about what the Los Angeles of the future will look like. If sprawl has indeed “hit the wall,” there will be opportunities to create something different.

A new bridge just beyond Hoover Dam

The road from Phoenix to Las Vegas crosses right over the top of Hoover Dam, one of the engineering marvels of the United States. Now travelers have a bypass route: a new bridge, the second tallest in the United States, was recently completed allowing travelers to avoid the slow, two-lane road over the dam.

Read more about the project at its official page.

Will the new bridge include guides who will tell you “take all the Dam photos you want!”?

Hottest housing market: Israel

Amidst housing troubles in many developed nations, an unlikely hot housing market has emerged in Israel:

Israel, despite perennial fears of war, has emerged as one of the hottest – and least likely – property markets in the world: Since real estate collapsed around the globe in 2008, at least one industry watchdog lists it as the fastest-rising property market on earth…

According to Global Property Guide, a trade magazine that monitors the housing market, Israeli housing prices in the second quarter of 2010 rose sixth-fastest in a ranking of 36 countries. Four of the top five, including Singapore and Latvia, were rebounding from sharp price drops. So looking at the past two years ended in June – the last period for which there is data – Israeli real estate clocks in at No. 1.

For Israel, where high-tech and science are booming businesses, the property price spike is the latest claim to fame. But it’s one officials aren’t boasting about, given ample evidence of how an imploding bubble can shatter decades of economic growth.

What is interesting to note is that Israeli officials are working to cool down the housing bubble so that their country doesn’t join other nations in experiencing a burst housing bubble. If their actions are any indication, might most developed countries now pursue policies that try to even out the housing market over time to avoid any possible issues with booms or busts? And if so, how effective can central governments be in attempting to control the housing market?

Predicting the fastest growing American cities for the next 40 years

Forbes has a new list of what they think will be the fastest growing cities in the United States in the next 40 years. Not surprisingly, the top 5 are all in the South and West. Perhaps surprisingly, these cities are “little big cities,” places that grown in the last few decades and are poised for new growth. Here are the top cities for growth: Raleigh-Durham, North Carolina; Austin, Texas; Salt Lake City, Utah; San Antonio, Texas; Oklahoma City, Oklahoma.

Forbes says they are using a different methodology to select these cities:

In developing this list we have focused on many criteria–affordability, ease of transport and doing business–that are often ignored on present and future “best places” lists. Yet ultimately it is these often mundane things, not grandiose projects or hyped revivals of small downtown districts, that drive talented people and companies to emerging places.

This methodology seems to emphasize “softer factors” like affordability and quality of life. I almost wish we could just fast forward forty years to see how accurate this is. What would others predict and what factors would they use?

But I can see some of the logic. These places offer some of the amenities of the big city and are vibrant places where things are happening. Couple this with affordable homes, some jobs, and less congestion and I could see how it is appealing. Additionally, 8 out of the top 10 are in the South and West – only Columbus, Ohio and Indianapolis, Indiana are outside these regions. It would make sense that the growing areas of the country are the places where these mid-sized cities are growing.

Classic Onion parody of family moving from the city to suburbs

One of the classic headlines (2001) from The Onion: “Family of Five Found Alive in Suburbs.” A few bits from the story tracking a family that disappeared from Chicago and was found again years later in Buffalo Grove:

Rescuers discovered the five-person clan after a survey plane spotted a crude signal fire the family had created in a barbecue grill…

To protect themselves from the elements, the Holsapples fashioned a three-bedroom, ranch-style lean-to with brick facing and white aluminum siding. During their years on the acre-and-a-half lot, the Holsapples faced many hardships, including septic-tank backups, frequent ant infestation, and the threat of rezoning to erect an industrial park across the street.

“The Holsapples were in pretty bad shape when we found them lying lifelessly on their patio furniture,” paramedic Mary Gills said. “Their stomachs were bloated from years of soda and fast food, and they were all suffering from severe cultural malnutrition.”…

According to University of Illinois– Chicago anthropologist Dr. Arthur Cox, to survive such an emotionally, culturally, and spiritually barren place, the Holsapples were forced to “go native.”

“Much like those stranded in remote islands, the Holsapple family looked to the indigenous population to learn techniques for adaptation and survival,” Cox said. “Shocking as it is, one eventually becomes acclimated and then numbed to the theme restaurants, cinema multiplexes, and warehouse-sized grocery stores.

Interestingly, this is exactly the sort of story that opponents of suburbs might write: the family disappeared into a vast wasteland with no culture. The story contains a number of typical criticisms about suburbs: spiritually dead, no culture, out in the middle of nowhere (particularly when cities are considered to be the center of the universe), primitive life, mind-numbing, requiring the ability to shop and be entertained at garish facilities, and so on.

Of course, when it is written in this style, it all sounds quite funny.
