The Chicago Tribune’s Instagram feed of their vintage photos

The Chicago Tribune has an Instagram account featuring vintage photos of the city. See highlights here.

One quick thought: the downtown looks remarkably different today including a very different kind of development along the East Branch of the Chicago River, the rise of gleaming skyscrapers in the Loop and elsewhere (the International Style), and a generally cleaner look (though perhaps the consistent black and white portrayal makes a big difference).

The world’s first nuclear reactor – buried in a Chicago suburb

A photographer describes going to the suburbs to find the world’s first nuclear reactor:

“I was working at Fermilab, and that research led me to this space. It’s in a forest preserve near Palos Heights, in an area called Red Gate Woods, and in those woods is Site A, where the first nuclear reactor ever created was buried in 1955. There’s also a site called Plot M, where all the waste from that experiment was buried while it was actually happening. Six stones designate where the waste is buried. The stones in the photo mark that area…

Note: According to information from the U.S. Department of Energy provided by Cook County, “the area surrounding Site A and Plot M continues to undergo annual monitoring and remains safe by all measurements.” The DOE did not respond to inquiries by presstime.

Read more about the site here. It’s interesting that this combines two key markers of post-World War II American life: the Atomic Age and suburban sprawl.

Chicago Lucas museum to have to deal with garbage underneath

Chicago may have a beautiful waterfront but plans for the Lucas museum provide a reminder of how that land was acquired: garbage.

“Any design will account for existing environmental issues and be built accordingly,” an Emanuel spokesman said. “The mayor has been clear. No public dollars will be spent on construction of the Lucas museum.”With Emanuel’s backing, Lucas is proposing a five-acre museum nestled on 17 acres of Chicago parkland just south of Soldier Field. But what’s buried below the surface of the site is nasty stuff. An analysis for the renovation of Soldier Field and the land around it more than a decade ago found potentially cancer-causing chemicals in the soil near the stadium, according to a site inspection report filed with the Illinois Environmental Protection Agency…

The contamination discovered around Soldier Field is believed to be the byproduct of burning wood, coal and other materials. Embankments, parking lots and other paved surfaces around the stadium serve as barriers eliminating human exposure to the buried pollutants. Plans call for some of that area to be dug up as Lucas proposes moving 3,000 parking spaces underground. The project’s proximity to Lake Michigan also is a factor for environmental planning.

I remember seeing a small exhibit of some of this garbage at the Field Museum about 10 years ago. On a small plot just outside their building they had found a wide range of items including utensils and tea cups and saucers from hotels.

Since there are environmental concerns at this particular site, I wonder how close residents and visitors are to these dangerous materials at other points along the lakefront. Just how deep would one have to dig to find the garbage? How much work does it take to contain the problems when constructing new buildings?

Report on Chicago manufacturing: “punching below its weight”

Chicago’s rise was aided by manufacturing but a new report says manufacturing in the region is lagging:

While the 14-county tri-state area was the fourth-largest exporter among the 100 top metro areas nationwide in 2012, it fell to the middle of the pack on gross domestic product growth, export growth and exports as a share of economic activity, according to “Revival in the Heartland: Manufacturing and Trade in Chicago,” a report to be released Wednesday by HSBC Bank and the Chicago Council on Global Affairs.

“Manufacturing in Chicago is an old heavyweight slugger, punching below its weight,” the study stated, noting that it remains the second-largest economic driver in the region after government and social services…

Study authors and individual manufacturers cite a range of historical factors that have contributed to the weak performance:

•A lack of civic and government attention to the sector because of a perception that it was dying.

•An absence of intraregional cooperation on economic issues.

•Freight rail gridlock.

•Lingering wariness about expanding business within the state, given its fiscal problems.

The article notes the ongoing loss of manufacturing jobs in recent decades, even on top of the decline of such jobs in the 1960s and 1970s. The initial drop significantly impacted social conditions, as noted by William Julius Wilson in his writings. Even as Chicago has avoided the decline narrative associated with numerous other Rust Belt cities (Detroit as a common example but also including places like Cleveland, Buffalo, Youngstown, and numerous other cities), a steady decrease in manufacturing continues to present challenges.

Appraisals based on neighborhood sales contribute to price differentials in Chicago

Home appraisals are often based on nearby properties, leading to large price differences and lending practices across Chicago neighborhoods:

That means if you’ve got an area with lots of boarded up houses and lots of extremely low value sales, then it’s likely that even a newly rehabbed house would be appraised at a lower price. Hobbs says that’s because most residential appraisals are determined by comparing that property with ones that have recently sold in the neighborhood.

“In the desirable neighborhoods, there’s an insufficient amount of inventory or supply and therefore buyers are competing even more ferociously to be in place, to be the one individual or family that is successful in buying that property,” he said.

So in an area like Lincoln Park, that demand drives prices way up, even beyond peak prices. And appraisers and banks feel comfortable with that because they have the numbers to back it up. But when someone wants to make a traditional purchase in a marginal area like Lawndale, appraisers and lenders are more conservative, especially after what happened during the housing crisis…

Rose said in the post-bubble market, banks are putting more weight on the value of a property than they did before. He thinks using cash transactions and distressed sales as comparables doesn’t really give a true market sense for what a house should sell for.

Another point in favor of living in hot or desirable neighborhoods: lenders are more likely to make loans. In contrast, economically depressed neighborhoods have a tougher time recovering unless lending institutions decide to make an investment or people have cash or capital to get past the lower appraisals. This could have the effect of reinforcing residential segregation for long periods of time.

As they say in real estate, it’s all about location, location, location…

Statistical anomalies show problems with Chicago’s red light cameras

There has been a lot of fallout from the Chicago Tribune‘s report on problems with Chicago’s red light cameras. And the smoking gun was the improbable spikes in tickets handed out on single days or in short stretches:

From April 29 to June 19, 2011, one of the two cameras at Wague’s West Pullman intersection tagged drivers for 1,717 red light violations. That was more violations in 52 days than the camera captured in the previous year and a half…

On the Near West Side, the corner of North Ashland Avenue and West Madison Street generated 949 tickets in a 17-day period beginning June 23, 2013. That is a rate of about 56 tickets per day. In the previous two years, that camera on Ashland averaged 1.3 tickets per day…

City officials insisted the city has not changed its enforcement practices. They also said they have no records indicating camera malfunctions or adjustments that would have affected the volume of tickets.

The lack of records is significant, because Redflex was required to document any time the operation of a camera was disrupted for more than a day, as well as work “that will affect incident volume” — in other words, adjustments or repairs that could increase or decrease the number of violations.

In other words, graphs showing the number of tickets over time show big spikes. Here is one such graph from the intersection of Halsted and 119th Street:

As the article notes, there are a number of these big outliers in the data, outliers that would be difficult to miss if anyone was examining the data like they were supposed to. Given the regularities in traffic, you would expect fairly similar patterns over time but graphs like this suggest something else at work. Outside of someone directly testifying to underhanded activities, it is difficult to imagine more damaging evidence than graphs like these.

Fighting to protect Chicago’s parks from mini-banks, tea stores, and the Lucas Museum

Curbed Chicago sets up the likely coming battle over using public space for the Lucas Museum:

Since late Spring, a small “pop-up bank” operated by PNC Bank has sat in Grant Park. It’s a bright orange and blue shipping container with doors and windows and an ATM. The park district earns $120,000 annually from the small structure, but many folks are not happy with its location in the park. DNAInfo has reports of numerous complaints about the very idea of a bank opening “It seems to go against the nature of the park itself,” a citizen tells DNAInfo.

The Park District is okay with it, obviously, in part because of the payola but also because, according to them, it’s not a permanent structure. In their mind, it’s a temporary vendor like you might find several dozen of in the park during Taste of Chicago. But is it the same? And where are the limits? What if Starbucks wants to open a mini-cafe right next to the PNC to capture the millions of visitors Grant Park will receive this summer? Why wouldn’t they?…

And consider Connors Park, to the north of downtown a few blocks from John Hancock tower. The squat little park is now home to an Argo Tea pavilion which just celebrated its one year anniversary of the location. Initially there was confusion about whether the park was still a park, and if it was okay to sit and enjoy the park without buying a tea. At a celebration for the one year anniversary, staff told us that with recent changes to the signage that confusion has dissipated and that neighbors know they’re welcome…

But the fact that these two issues are even issues at all speaks to the city’s constant vigilance against abuse of the parks, and it explains why despite being a seeming “slam dunk,” the Soldier Field parking lot location chosen for the Lucas Museum won’t come without a fight. This isn’t a quarter-block tea house or a 160 square-foot mini-bank, it’s a massive, multi-million-dollar development that has already captured the attention of the nation. As Chicagoist puts it, The Debate Over The Lucas Museum Has Only Started.

There are two levels to this:

1. What seems like an increased interest in many cities in ensuring that public spaces stay public. What can happen in these parks? Is there enough public space as opposed to private space masquerading as public space?

2. The special circumstances in Chicago that suggest the land near the lake needs to remain for public use. All sorts of ideas can pop up for a lakefront – I was reminded again recently about the older Mayor Daley’s suggestion that Chicago should build a major airport out in Lake Michigan – so having these guidelines has been a big boon. Yet, it is hard for a city that is chasing elite status (perhaps due to its own insecurity) to turn down a figure like George Lucas in such a location. Additionally, such a battle could give opponents of Rahm Emanuel an excuse to pick a battle.

Maybe all this represents one of the major trade-offs in today’s world: just how much do want corporate interests or the interests of powerful people overrule the rights of others? Constructing a museum like this isn’t the end of the world for Chicago but it may seem like another event in a long line of concessions to growth machines.

Chicago to collect big data via light pole sensors

Chicago is hoping to collect all sorts of information via a new system of sensors along main streets:

The smooth, perforated sheaths of metal are decorative, but their job is to protect and conceal a system of data-collection sensors that will measure air quality, light intensity, sound volume, heat, precipitation, and wind. The sensors will also count people by observing cell phone traffic…

While data-hungry researchers are unabashedly enthusiastic about the project, some experts said that the system’s flexibility and planned partnerships with industry beg to be closely monitored. Questions include whether the sensors are gathering too much personal information about people who may be passing by without giving a second thought to the amount of data that their movements—and the signals from their smartphones—may be giving off.

The first sensor could be in place by mid-July. Researchers hope to start with sensors at eight Michigan Avenue intersections, followed by dozens more around the Loop by year’s end and hundreds more across the city in years to come as the project expands into neighborhoods, Catlett said…

While the benefits of collecting and analyzing giant sets of data from cities are somewhat speculative, there is a growing desire from academic and industrial researchers to have access to the data, said Gary King, director of the Institute for Quantitative Social Sciences at Harvard University.

The sort of data collected here could be quite fascinating, even with the privacy concerns. I wonder if a way around this is for the city to make clear now and down the road how exactly they will use the data to improve the city. To some degree, this may not be possible because this is a new source of data collection and it is not entirely known what might emerge. Yet, collecting big data can be an opaque process that worries some because they are rarely told how the data improves their lives. If this simply is another source of data that the city doesn’t use or uses behind the scenes, is it worth it?

A quick hypothetical. Let’s say the air sensors along Michigan Avenue, one of Chicago prime tourist spots, shows a heavy amount of car exhaust. In response to the data, the city announces a plan to limit congestion on Michigan Avenue or to have clean mass transit. This could be a clear demonstration that the big data helped improve the pedestrian experience.

But, I could also imagine that in a year or two the city hasn’t said much about this data and people are unclear what is collected and what happens to it. More transparency and clear action steps could go a long way here.

Fighting over the fate of the Lathrop Homes, one of the remaining public housing projects in Chicago

While Chicago’s public housing high-rises (like Cabrini-Green) have been torn down, there is a current debate about the fate of the Lathrop Homes:

Lathrop’s two-story row houses and three- and four-story walk-ups occupy 35 acres on the western edge of Lincoln Park, and are often noticed by passersby on Diversey owing to the thick, white plumes of steam that rise from ground vents like jets from primordial geysers—the result of aging heating pipes. When the 925-unit development opened in 1938, it was one of the first public housing developments in the country and only the second in Chicago, built by a dream team of architects for the Public Works Administration’s New Deal program. For 30 years it was one of four all-white public housing projects managed by the Chicago Housing Authority. When the first African-American families were finally allowed to move into Lathrop in the late 1960s, they were segregated in the buildings on the south side of Diversey. The project didn’t become the melting pot Suarez describes until the 1970s…

Though Lathrop was supposed to be rehabilitated—and to remain 100 percent public housing—the CHA’s position shifted over the years. In 2000 the CHA stopped accepting new residents (in anticipation of rehabbing the property), and each subsequent year families were encouraged to move out. The buildings were shuttered one by one as Lathrop shrank from 747 occupied units in 2000 to about 140 today.

In other words, at a time when affordable housing in Chicago was becoming more and more scarce, hundreds of low-rent apartments were sitting vacant in a prime neighborhood.

In 2006 the CHA announced that Lathrop would become a mixed-income community with 400 public housing units, 400 tax-credit-subsidized units, and 400 market-rate ones. Demolition was scheduled for 2009.

But the housing market collapse, the recession, and persistent leadership turnover at the CHA has stalled those plans. To this day, not a single one of Lathrop’s 30 buildings has been demolished.

Interesting read about a project that is on the National Register of Historic Places and doesn’t get much attention despite some unique features. The story of the slow-moving CTA is not unusual; that has been the story for decades and it is understandable why residents aren’t always optimistic about better outcomes.

Man fills Chicago potholes with mosaic art

Chicago has had plenty of potholes in recent months and one man has taken to filling a few potholes with art:

The perfect pothole might not exist for many people — but for mosaic artist Jim Bachor, it’s one with a nice oval shape. Bachor began filling those potholes a little more than a year ago, after one in front of his house became a hassle.

Bachor doesn’t just fill them with cement, though. He’s turned pothole-filling into a public art project — one with a sense of humor. He fills them with mosaics.

“I just think it’s fun to add that little bit of spark into (an) issue that people moan about,” says the Chicago resident, whose work also hangs in galleries. He was first drawn to the ancient art form because of its ability to last.

With orange cones and vests displaying his last name, Bachor and his helpers look official enough to shut down a street section to work on filling a pothole.

Bachor uses the Chicago city flag design in his pothole art. Some versions hold phone numbers to local auto repair shops, while others simply read “POTHOLE.” His most recent installment north of downtown Chicago — “(hash)21914” — pokes fun at the huge number of potholes that exist in the city.

Public art that also helps the city fulfill one of its basic duties. How long until he is shut down for not filling potholes to standards or because it leaves the city liable?

It would be interesting to test the durability of mosaics in potholes. Given their construction with numerous small pieces, wouldn’t they be particularly susceptible to pressure, water, and freezing? I suspect there are much better ways to address potholes but they may not look as good or have any moxie.
