See how Chicago is a low-rise city from this 360° photo

I love the new perspectives that taking photographs from a DJI Mavic Pro quadcopter is showing me.

Chicago is a very large city, by land area, and has a low average neighborhood density. This 360° photo, taken from the corner of Ohio Street and Kilbourn Avenue in Humboldt Park, shows the cityscape five and a half miles west of downtown Chicago. It shows the cityscape west of this point, and north and south.

A little southwest of the center point is a small group of mid-rise buildings at the west side of Garfield Park. One of the buildings, the Guyon Hotel, has been abandoned for a while, and another is a residential building for senior citizens that’s undergoing a complete renovation.

Chicago’s “four tallest skyscrapers” are easily visible in the background; from north to south you’ll see the John Hancock tower, the Trump International Hotel & Tower, the Aon Center, and the Sears (Willis) Tower.

At least 2.5 percent of the land area in Chicago is covered in parking lots and garages

Here’s how I know that at least 2.5 percent of the land area in Chicago is covered in parking lots and garages, as of February 5, 2017.

That’s a lot of polluted water runoff.

I grabbed the land area of 227.3 from the Wikipedia page.

I grabbed all the parking lots from OpenStreetMap via Metro Extracts, which is going to be the most complete map of parking lots and garages.

Volunteer mappers, including me, drew these by tracing satellite imagery.

With the parking lots data in GIS, I can count their area in square feet, which comes out to 160,075,942.42. Convert that to square miles and you get 5.74.

5.74/227.3*100 = 2.5 percent

The last snapshot of parking lot data I have is from February 2016, when only 3.39 square miles of parking lots have been drawn.

There are still many more parking lots to be drawn!

There are still $1 lots that no one has applied for

I’d like to point out my story on the Chicago Cityscape blog highlighting the fact that ~1,800 city-owned lots that are being sold to $1 to nearby property owners that haven’t been applied for. The City of Chicago is selling 3,844 vacant lots for $1 in these 34 community areas, but the city has received only 2,031 applications.

They didn’t pave paradise, but they still put up a parking lot

Two light industrial building were purchased and demolished in order to build more car parking for WMS Gaming in the Avondale community area. Congratulations on the success of WMS Gaming that they are hiring more people, but this kind of development is transit “dis-oriented”.

Nearly an entire block face of California from Melrose to Roscoe will have a surface parking lot. Across the street to the west, and across the street to the south is entirely residential.

The Chicago Department of Planning and Development staff wrote in their report to the Chicago Plan Commission that the project “Promotes economically beneficial development patterns that are compatible with the character of existing neighborhoods (per 17-8-0103) as evidenced by the compatibility of off-street parking within the broader industrial park character of the surrounding area.”

The Plan Commission had to approve the demolition of these buildings and the additional parking lots because they were not allowed in Industrial Planned Development 1151.

The change was neither an economically productive use of the land, nor is it “compatible with the character” of half of the surrounding area.

This might be economically productive for WMS Gaming, so more of its workers can drive. But there are more ways to get around than driving.

WMS Gaming is near the 52-California bus route. It’s also two blocks from the 77-Belmont bus route and 152-Addison bus route. WMS Gaming can operate a shuttle to CTA or Metra stations.

Turning what was – and still could be – productive space has now been turned into entirely productive

Barcelona’s superblocks are being implemented now to convert car space to people space

Most of the urban block pattern in Barcelona is this grid of right angles (like Chicago) with roads between blocks that range from small to massive (like Chicago). Barcelona’s blocks, called “illes”, for islands*, are uniform in size, too. This part of Barcelona is called Eixample, designed by ldefons Cerdà in 1859.

The city is rolling out its urban mobility plan from 2013 to reduce noise and air pollution, and revitalized public spaces. Part of this plan is to reduce car traffic on certain streets in a “superblock” (the project is called “superilles” in Catalan) by severely reducing the speed limit to 10 km/h.

Vox published the video above, and this accompanying article. The project’s official website is written in Catalan and Spanish.

My favorite quote from the video is when someone they interviewed discussed what tends to happen when space for cars is converted to space for people:

“What you consistently see is when people change their streetscapes to prioritize human beings over cars is you don’t see any decline in economic activity, you see the opposite. You get more people walking and cycling around, more slowly, stopping more often, patronizing businesses more. That center of social activity will build on itself.”

A superblock is a group of 9 square blocks where the internal speed limit for driving is reduced to 10 km/h, which is slower than most people ride a bicycle.

A superblock is a group of 9 square blocks where the internal speed limit for driving is reduced to 10 km/h, which is slower than most people ride a bicycle. That’s the second phase, though. The first phase reduces it first to 20 km/h. During phase 2, on-street parking will disappear. In addition to the reduced speed, motorists will only be able to drive a one-way loop: into the superblock, turn left, turn left, and out of the superblock, so it can’t be used as a through street even at slow speeds, “allowing people to use the streets for games, sport, and cultural activities, such as outdoor cinema” (Cities of the Future).

A grid isn’t necessary to implement the “superblock”; it can work anywhere.

In Ravenswood Manor, the Chicago Department of Transportation is testing a car traffic diverter at a single intersection on Manor Avenue, where drivers have to turn off of Manor Avenue. This effectively creates a small superblock in a mostly residential neighborhood, but one that is highly walkable, because schools, parks, a train station, and some small businesses are all within about four blocks of most residents.

The trial is complementary to an upcoming “neighborhood greenway” project to use Manor Avenue as an on-street connection between two multi-use trails along the Chicago River.

The Vox video points out that “walkable districts are basically isolated luxury items in the United States”. I agree that this is often the case, although NYC, pointed out as a place where people spaces are being made out of former car-only spaces, is spreading its “pedestrian plaza” throughout all boroughs.

Ravenswood Manor is a wealthy area, but the reason this project is being tried there and not one of the dozens of other places where a lot of car traffic makes it uncomfortable or dangerous to walk and bike is because of the need to connect the trails.

The diverter should drastically reduce the amount of through traffic in the neighborhood. Its effect on motorists’ speeds will be better known when CDOT finishes the test in November.

A worker installs a barrier identifying the entrance to a “superilla” (singular superblock) last month. Calvin Brown told me, “I prefer the name ‘super islands’ because it is more poetic and captures the peaceful setting that they create.” Photo via La Torre de Barcelona.

I see a connection between the “superilles” plan in Barcelona, and what CDOT is piloting in the small neighborhood. The next step for CDOT is to try iterative designs in this and other neighborhoods and start converting asphalt into space for other uses, but we may have to rely on local groups to get that ball rolling.

I had the great fortune of visiting Barcelona a year ago, and I had no idea about the plan – but I was impressed by Cerdà’s design of Eixample. I will return, and next time I’ll spend a little time bicycling around.
