A new map for finding COVID vaccination sites in Illinois

The State of Illinois map of COVID vaccination sites is pretty bad. 

Screenshot of the Illinois Department of Public Health map, taken February 14, 2021.

It’s slow (caused my browser tab to crash after a couple minutes), has misspelled county and city names, missing ZIP code digits, and cannot be searched by address. There are duplicate entries, too.

I made a new version of the state’s COVID vaccination sites map.

I didn’t make any COVID maps earlier because I didn’t want to spend the time to ensure that I understood the right and wrong ways to map disease, because people make decisions based on maps and I don’t want my maps to end up harming anyone.

Aside from the state website’s usability issues, I’m very disappointed that there is zero data about COVID in the state’s #opendata portal.


These cities and counties have the most COVID vaccination sites, according to the IDPH’s dataset. 

For the top 10 or so, it seems to correlate with population. Except Skokie has 7 sites, and Evanston has 4, despite Evanston having 10,000 more residents. Nearly 100% of Illinois is within 60 minutes driving of the current COVID vaccination sites. (More are coming, at least in Chicago.) 

Nearly 100% of Illinois is within 60 minutes driving of the current COVID vaccination sites. (More are coming, at least in Chicago.)

And a lot of Illinois is still within 45 minutes driving of the current COVID vaccination sites. Really big gaps in geography appear at the 30 minutes driving threshold.

I’m working with some people to show access via transit. This is super important. I predict that upwards of 75 percent of Chicagoans will be able to access a vaccination site or two within 45 minutes and 100 percent within 60 minutes.

Here’s another shortcoming of the state’s map: Each site’s unique ID is not persistent, making it difficult to compare one day’s list to the following day’s list. I got around that by making a “hash” of each vaccination site and comparing between two versions.

The map has been updated once since I started. The “hash” creates a unique ID based on the attributes of each vaccination site (name, address, city, county, ZIP code). Any time one of those attributes changes, the hash will also change and thus I can more easily find new or modified vaccination sites.

Chicago’s Lake Street ‘L’ was originally supposed to be a monorail

I bought a copy of The “L”: The Development of Chicago’s Rapid Transit System, 1888-1932, written by Bruce Moffat, a historian of electric trains in Chicago. Moffat currently works for the Chicago Transit Authority. (If there wasn’t a pandemic, you’d be able to request a hold on one of the 50 copies at the Chicago Public Library.)

The book is about the elevated trains that were built in Chicago, in competition with the street omnibuses (horse drawn), railways (cable cars and streetcars), and suburban trains (okay, some competition), prior to establishing the Chicago Transit Authority. The CTA is a State of Illinois authority, created by the legislature, that today owns and operates all of the historic and since-built elevated, subway, and at-grade ‘L’ transit as well as buses. It acquired all of the assets of all of the ‘L’, streetcar, and bus companies that were operating when it was established in 1945.

On with the story!

Back in December 1888, the Chicago City Council approved a franchise for the Lake Street Elevated Company to build a Meigs Elevated Railway above Lake Street from Canal Street to 40th Avenue (later named Crawford and now Pulaski Road), then the western border of Chicago. A tract of land west of 40th Avenue (Pulaski Road) was incorporated into the City of Chicago four months later on April 29, 1889.

If you go to the intersection of Canal and Lake Streets today you’ll see the Union Pacific railroad tracks above, heading into and out of Ogilvie Transportation Center, a skyscraper at 444 W Lake Street, a cigar store, and a vintage loft office building.

The Meigs Elevated Railway was a steam-powered elevated monorail – meaning each track had one rail to support a train.

You may not know this: I love monorails. When my family visited Walt Disney World my favorite ride was the inter-park and world famous monorail. I’ve also ridden the monorails in Disneyland (but I don’t remember my time there), Las Vegas, Seattle, Düsseldorf airport, Wuppertal, and three in Tokyo, Japan (Chiba City, Shonan, and Haneda airport; I missed the one in Tama).

I used to be obsessed with monorails. I became a member of The Monorail Society when I was a teenager and my first eBay purchase was a Disney monorail motorized toy in March 2000. I was jealous of my friends in elementary school who had a Lego monorail, and now they regularly sell for $200. I also built a SAFEGE-style monorail out of K’NEX in high school.

A drawing of the Meigs Elevated Railway monorail, originally published in Scientific American, July 10, 1886. Via Wikipedia; also printed in Moffat’s book where it is sourced from Railway Age, a trade journal founded in 1856 that still exists today.

It was invented by Josiah V. Meigs in Cambridge, Massachusetts; a 227-foot long demonstration line was built in 1886 on land that is now a Fairfield Inn hotel and before that was the Genoa Packing Co. (demolished in 2013).

The Meigs Elevated Railway Wikipedia article has two photos of a plaque that was on the exterior wall of the Genoa Packing Co. The new hotel building does not have the same plaque.

The Lake Street Elevated Company organizers (seven incorporators are listed in the book) hired Morris H. Alberger to be the president. According to Moffat’s book, “Alberger had convinced his fellow directors that their railroad should use an experimental and relatively complex elevated railway system developed by Joe V. Meigs”. Alberger was also the president of the Meigs Elevated Railway Company.

Moffat discusses an eighth company organizer: Michael Cassius McDonald, “politically well connected and influential”. He was the “chief sponsor” and “promoter” of the Lake Street elevated proposal which came to be known as “Mike’s Upstairs Railroad”.

The Meigs Electric Railway – the monorail – was never built. Moffat says that the reason the monorail was never built was because it was difficult to promote and raised funds by selling shares.

Almost a year after City Council approved the MER to run over Lake Street, they “deleted the Meigs requirement” in November 1890 so that the Lake Street Elevated Company could build a traditional iron structure. The trains would also be “traditional”. (The first elevated train started running in Manhattan and the Bronx on August 26, 1878 – that was the Third Avenue Elevated – ten years prior to the Meigs monorail being approved in Chicago.)

Even before City Council “deleted” the franchise’s requirement to build a monorail, the Lake Street Elevated Company had already started building the iron structure for a train in December 1889, at Lake and Clinton Streets, where the Clinton Green Line station is now.

That’s the end of the story for the monorail, but I’ll continue talking about the Lake Street ‘L’.

The Lake Street Elevated opens!

Construction had reached “just west of Ashland Avenue” by October 1892, less than three years after the first iron girder was erected at Clinton. A year after that last construction milestone at Ashland, the tracks for service were completed to California Avenue (2800 West).

The Lake Street Elevated Company’s first service was set to begin on October 30, 1893. The opening was delayed, however, until an inauguration on Saturday, November 4, 1893, to mourn the death of Mayor Carter Harrison, who was assassinated during his fifth term. Passenger service began two days later on Monday, November 6, 1893.

Service was extended into the Loop elevated tracks in 1895.

Heading closer to downtown Chicago

In early 1893, the Lake Street Elevated Company wanted to run their trains down Market Street (now Wacker Drive) from Lake Street to Madison Street.

The Market Street “stub” ran past the future site of the Civic Opera Building, opened in November 1929. Operagoers and workers in the office tower of the building would have ridden the ‘L’ here until the Chicago Transit Authority

The Lake Street Elevated’s Market Street stub terminated at Madison Street. The Civic Opera Building is on the left. Image is from the CTA’s collection. Market Street was renamed Wacker Drive when the street was reconstructed as a double decker street starting in 1948.

Extending further into the Garfield Park neighborhood

Tracks were built six blocks west of California Avenue, to Homan Avenue, but the stations were incomplete. Service to the Homan station started November 24, 1893, and four blocks further west to Hamlin Avenue in January 1894.

The Homan Avenue station no longer exists. Today’s Green Line over Lake Street was rebuilt from 1994 to 1996 and the Homan station was abandoned. According to Chicago “L”.org, the CTA decided to move the station two blocks west to Central Park Drive (3600 West). It was “completely deconstructed in spring of 2000 and put into storage”. It was renovated, made accessible, and opened as the Conservatory-Central Park Drive station in June 2001.

Chicago “L”.org notes that this visitors access to the Garfield Park Conservatory, evens out stop spacing, but does not intersect a bus route which Homan Ave does. The CTA closed Hamlin station on March 18, 1956. I don’t know when it was demolished.

Onward, to Austin and Oak Park!

Back to the Lake Street elevated timeline. Serviced operated to Hamlin Avenue in 1894. The next year it was operating to 52nd Avenue (now Laramie Avenue), the western boundary of Chicago. On the other side of that boundary was the Township of Cicero. Austin, a township neighborhood, was annexed by Chicago in 1899. The Village of Oak Park eventually emerged from the township, incorporating in 1902.

Austin was location of Cicero’s town hall. The town hall building, at the Central and Lake station, is now part of the Austin Town Hall Park and Cultural Center, owned and operated by the Chicago Park District.

Moffat’s book describes a lot of political controversy about extending the Lake Street Elevated into Cicero, which seems fitting for the Chicago region. Passenger service to Austin Avenue (now Boulevard) started April 19, 1899.

The next month, on May 14, 1889, trains that ran east-west above Lake Street came down a ramp – to the surface – onto north-south Lombard Avenue a couple of blocks south to Randolph Street. They turned west onto Randolph Street and continued until Wisconsin Avenue/Marion Street. The tracks on Randolph Street were in the middle of the street, and owned by Suburban Railroad, an interurban railway company.

The tracks were previously owned by Chicago, Harlem & Batavia Railway. I’m including that information because I grew up there. However, the railroad never made it that far: “No effort was made to extend the railroad to that distance place, but money was spent to purchase new locomotives and passenger cars and make other improvements.”

Residents here had the option of taking trains into downtown Chicago on the Chicago & Northwestern Railway. Those tracks are now owned by Union Pacific, which also operates the former C&NW lines as Metra’s UP-West Line. The line terminates at Ogilvie Transportation Center, which used to be called Northwestern Station, which was C&NW’s second location for their downtown terminal.

Moffat discussed these passengers’ choices, writing, “Although a ride on the nearby Chicago & Northwestern was faster, the “L’s” more frequent schedule, convenient Loop stops, and lower fare drew many riders away from the steam railroad”. The same is true today; the ‘L’ costs less than Metra but takes longer to reach the West Loop.

The story about the construction and operation of the Lake Street Elevated is almost done. I’m going to end it as soon as the train reaches the current terminus at Harlem Avenue in Oak Park.

Service to Marion Street started in late January 1901, on the street level of South Boulevard, thus ending service on Randolph Street a few blocks south. Trains started servicing the Harlem station on May 20, 1910. Remember that the reason the trains are now on South Boulevard is because Lake Street runs with a slight northwest diagonal, ends at the Chicago & Northwestern Railway embankment, and resumes a few blocks west. In 1961, the line was elevated onto C&NW’s embankment.

Even though the station is currently called “Harlem/Lake”, the station is at Harlem/South Boulevard, and Lake Street is one block north.


N.B.

Meigs’s railway was mentioned in an op-ed in the Boston Globe Magazine on Sunday, February 23, 1992, as the newspapers’s architecture critic, Robert Campbell, and Peter Vanderwarker, an architectural historian, lamented the towering car infrastructure proposed in the Central Artery/Tunnel Project (also known as “Big Dig”, the most expensive highway construction in the country), as well as the darkening effect of the elevated trains. It’s really quite an essay.

The op-ed in the Boston Globe Magazine, 2/23/1992

But competition was vicious. Arson and vandalism hampered Meigs, as did his insistence on old-fashioned steam power instead of electricity. Nothing besides the Cambridge test line was ever built. The Meigs monorail made its last run in 1894. Conventional elevated trains, modeled on those of Manhattan and far more massive than Meigs’, soon darkened Boston’s streets.

By the end of this decade, the view will have changed radically. A dramatic Babel of steel and concrete, perhaps resembling a great sports stadium, will rise like a gray mountain in the middle distance at the left of the photo. The introverted automobile will have won its long battle for supremacy over the sociable train.

“MEIGS ELEVATED RAILWAY – Changing TRACKS”, By Robert Campbell and Peter Vanderwarker

Meigs Field, a former airport in downtown Chicago that existed between 1948 and 2003, was named after Merrill C. Meigs, a pilot and former head of the Chicago Aero Commission. He believed that Chicago needed a third airport, within 10 minutes of downtown. The airport was built and named after Meigs in 1949. I haven’t found a relationship between the two Meigs.

Chicagoland’s massive parking footprint – as measured on September 16, 2018

Using the footprints of parking lots and garages drawn into OpenStreetMap as a data source, the area of land in Chicagoland occupied by parking lots and garages is 247,539,968 square feet. (The data was exported using HOT Export Tool; you can replicate my export.)

That converts to:

  • 5,682.71 acres
  • 8.88 mi^2 (square miles)
  • 22.99 km^2 (square kilometers)
  • ≈ 0.26 × area of Manhattan (≈ 87 km^2 )
  • 3.9% area of Chicago is parking (Chicago is ~589.56 km^2 )

(I forgot to measure the portion of this within Chicago, and now the data snapshot is gone. I fixed this in the 2019 report.)

Why Jefferson Park residents should allow more housing

Short answer: To provide more shoppers for the local businesses. Read on for the longer answer. 

Over on Chicago Cityscape I added a new feature called “market analysis” which measures the number of people who live within specific walking areas (measured by time) and driving areas (measured by distance). 

I am in favor of removing apartment & condo bans in Chicago, especially in areas where they were previously allowed and near train stations.

Jefferson Park is centered around two co-located train stations, serviced by CTA and Metra respectively. There have been multiple proposals for multi-family housing near the stations (collectively called the Jefferson Park Transit Center) and some have been approved. 

Always, however, there are residents who resist these proposals and the number of originally proposed apartments or condos gets reduced in the final version (classic NIMBYism). 

There’re four reasons – at least – why more housing should be allowed near the Jefferson Park Transit Center:

  • Locally owned businesses require a significant amount of shoppers who live nearby and walk up traffic
  • More people should have the opportunity to live near low-cost transportation
  • It will include more affordable housing, through Chicago’s inclusionary zoning rules (the Affordable Requirements Ordinance, ARO)
  • There will be less driving, and therefore lower household transportation costs and less neighborhood pollution

To support the first reason, I used the “market analysis” tool to see just how many people live in a walkable area centered around Veterans Square, a mixed-use office and retail development adjacent to the train stations. 

Only 9,368 people live within a 10 minute walk to Veterans Square (get the Address Snapshot). 

Comparatively, 19,707 people live within a 10 minute walk to The Crotch, or the center of Wicker Park, at the intersection of Milwaukee/North/Damen (get the Address Snapshot). The Blue Line station is about 75 feet south of the center point.

I would grant the low Veterans Square number a small discount based on the proximity to the Kennedy Expressway, which severely truncates walking areas up and down the northwest side. Still, even with that discount, ending up with less than half the amount as the one in Wicker Park, is disturbing. Wicker Park is hardly characterized by high-density housing. In fact, all of the new high-rises are just outside the 10 minute walk shed!

In sci-fi, even parks get turned into parking lots

In one of Philip K. Dick’s short stories, titled “Precious Artifact”, Dick appears to recognize what tends to happen in American cities. 

Earth, “Terra”, has been attacked by “Proxmen” and the “Terrans” have lost. However, one of the Terrans, who has been reconstructing Mars for future Prox inhabitation has come back to Earth. A guide meets him at the spaceport and asks the Terran where he wants to go…

“I’m Mary Ableseth, your Tourplan companion. I’ll show you around the planet during your brief stay here.” She smiled brightly and very professionally. He was taken aback. “I’ll be with you constantly, night and day.”

“Night, too?” he managed to say.

“Yes, Mr. Biskle. That’s my job. We expect you to be disoriented due to your years of labor on Mars…labor we of Terra applaud and honor, as is right.” She fell in beside him, steering him toward a parked ‘copter. “Where would you like to go first? New York City? Broadway? To the night clubs and theaters and restaurants…”

“No, to Central Park. To sit on a bench.”

“But there is no more Central Park, Mr. Biskle. It was turned into a parking lot for government employees while you were on Mars.”

“I see,” Milt Biskle said. “Well, then Portsmouth Square in San Francisco will do.” He opened the door of the ‘copter.

“That, too, has become a parking lot,” Miss Ableseth said, with a sad shake of her long luminous hair. “We’re so darn over-populated. Try again, Mr. Biskle; there are few parks left, one in Kansas, I believe, and two in Utah in the south part near St. George.”

“This is bad news,” Milt said. “May I stop at that amphetamine dispenser and put in my dime? I need a stimulant to cheer me up.”
