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.

Day two in Zurich: Combine transit and museums on a single pass

Zurich, Switzerland

I was taking pictures of the tram and when I got home I saw that all three people were staring at my camera. At Bellevue in Zurich.

The post for day 1, Friday, when I went to Mount Rigi, hasn’t been written yet. 

Today was a busy day, which is expected when you travel Steven Vance-style: efficiently (meaning you see a lot of stuff without wasting any time), alone, with a very good sense of what you want to do, where they are, and how you’ll get around.

I’m staying at Hotel Bristol, which came up in an Orbitz search as being a decent place less than $100 per night – that’s hard in Zurich, and even harder if you want a place near the Hauptbahnhof (Hbf). I knew that’s where I would be coming and going a few times to get to Lucerne, the mountains, or to buy cheap (relatively) dinner.

This morning, after eating a continental breakfast in the hotel, I walked a couple of blocks from the hotel to the Hbf – I’m measuring blocks in a Chicago-sense. It was about 4-5 minutes to the nearest station entrance to buy the ZurichCard.

Getting the card was a no-brainer because for 24 CHF (Swiss Francs, about $25) you get a 24-hour public transit card and free entry to dozens of museums. It includes the city zone and the adjacent zones, including the airport. I have to leave for the airport tomorrow by 10 AM and I validated the card at 11 AM so I’m covered there.

After checking out and riding the city’s two funiculars and single rack railway, I visited the tram museum and national museum (Landesmuseum). Add to that the dozens of trams and buses I rode to reach the hill transport and two museums.

Consider that the cost of the train to the airport is 6.40 CHF, the tram museum is 12 CHF, and the Landesmuseum charges 10 CHF, I’d say I got more than my money’s worth.

What’s really great about the ZurichCard is that you can purchase it at any of ticket vending machine, including the ones labeled “SBB CFF FFS”* that also sell national railway and supra-regional tickets. You have to remember to validate the card right before your first use, either at a ZVV (Zurich regional public transport union) ticket vending machine.

My first transit trip this morning was on a fantastic double-articulated bus. That means it has three sections with five doors! These buses are only used on routes 31 and 33 in the city center, and they’re electric and silent, running on overhead trolley wire. The bus has the same priority and comfort as a tram, and multiple screens attached to the ceiling showing the next stop and its connections (transfers).

Zurich, Switzerland

The front two sections of a bi-articulated bus. It’s normally not possible to bring a bike on a bus or tram in Europe, except when the bus has been specially outfitted for the bike to be on the inside. Buses in Europe aren’t allowed to have bike racks on the front.

The tram system in the city center is the perfect complement and support for having so little driving here. Some of the streets restrict driving, and other streets have only a single lane in one direction, or just two lanes, one in each direction. Many of the major intersections within a mile of the Hbf surprisingly have no traffic controls.

Trams and buses load and unload passengers very fast because you can board through any door. “Winter mode” is enabled on many of the vehicles to keep passengers already on board more comfortable by opening doors at the stop only upon request (you push a button on the door).

Streetfilms published a video in 2014 discussing how the city administration has capped the number of parking spaces across the city: if a new parking space is built, a parking space has to be removed in the city center.

Driving in the city center is thus primarily for leaving your parking space for elsewhere in the city or region, or the reverse. Trips are extremely convenient by tram or trolley bus.

Motorists are obliged to stop for people who want to cross the road in zebra crossings, and trams which are turning across the lanes. Then, unless a road sign or marking dictates the priority of a lane, the rule “yield to the motorist on your right” reigns.

I never waited more than 7 minutes for a tram (I know because the countdown signs never exceeded 7 minutes for the route I was going to ride) and the average was probably closer to 4 minutes. It seems that a majority of the time trams run in exclusive right of way and traffic signals are set up to prioritize their movement.

Transit signal priority isn’t a given in all cities with trams; in Amsterdam and Budapest it seemed the tram waited just as long for a “green” light as adjacent, same-direction motorists did.

At the tram museum I talked to a staffer there who was pointing out features in a model created by a city task force which was investigating a potential U-bahn (underground) system for Zurich. He said that a couple of years ago the museum hosted an event to talk about whether the city was better off without the system.

The consensus amongst the attendees was that the city was indeed better off without a subway because the trams have a higher frequency than what the subway would have had. Another point made was that the connections between trams are easier and faster than between other modes.

Nevertheless, a few underground stations were built, but they aren’t subways. Two tracks, 21 and 22, carry the two routes of the Sihltal Zürich Uetliberg Bahn (SZU), One goes up the Uetliberg mountain in the city and the other serves the Sihl valley suburbs. There are also three underground tram stations away from the city center on line 7.

Traffic on the local transit was lighter than yesterday. Many riders I saw today were headed to a hill to go sledding. It might also be a coincidence that I rode all three hill-climbing funicular and rack railway lines, as well as the train that goes up “Mount Zurich” (870 meters; its real name is Uetliberg).

The Dolderbahn heads up the hill from Romerhof to the Dolder recreation area. At least half of the passengers today were children going with their parents and friends to sled down a hill there.

The Dolderbahn is a rack (cog) railway that heads up the Adlisberg mountain from Römerhof to the Dolder recreation area. At least half of the passengers today were children going with their parents and friends to sled down a hill there.

The last word on Zurich: It’s very expensive to eat here. I paid 11.50 CHF (about the same in USD) for a “döner box” which is something I paid about $5 in Rotterdam. A döner box is fast food. The cheap beer that went along with it was $5, which I could probably get for less than $2 in Rotterdam.

* “SBB CFF FFS” is a set of three acronyms that when expanded mean “Swiss Federal Railways” in German, French, and Italian, respectively. It’s normally abbreviated to SBB – German is the most commonly spoken language in Switzerland. Each of the acronyms plus dot “ch” has its own website that loads the organization’s website in the respective language.

You want a plan for Logan Square infrastructure? Let’s try out the one we got

I posted a modified version of this post to Streetsblog Chicago.

extralarge

A group in Chicago says “current infrastructure” cannot handle ~120 more people moving into Logan Square. Ring the NIMBY warning bell!

Logan Square is more equipped to handle ten times that number of new residents than most neighborhoods.

The Greater Goethe Neighborhood Association’s (boundary map) Zoning and Planning Committee’s submitted their opinion on a proposed building on the corner of Milwaukee Avenue and Campbell Avenue to 1st Ward Alder Proco Joe Moreno.

They wrote, “Current infrastructure cannot sustain the increase in density and ZAPC would like to know how is this is being addressed by the City”.

“Of the 88 units”, DNAinfo Chicago reported, “28 would be studios, 48 would be one-bedroom units and 12 would be two-bedroom units.”

What’s wrong with current infrastructure that it can’t handle 120 new residents? The GGNA doesn’t say. 

The context of this demand is a bit unfortunate, as far as good city planning goes. The city is in no way required to respond with how the city is addressing how current infrastructure can or cannot handle 120 new residents. And neither is Alder Moreno. Neither the city nor the developer* are required to do anything to change infrastructure in the area.

Logan Square’s population is much, much less than its peak. These 120 new residents are in some ways making up for the loss in units in the neighborhood due to deconversions. And their supply will help stem any rapid rise in rent increases.

What would be a good outcome, I believe, is that there’s a process or three:

  1. Measure the impact of new housing on current infrastructure (housing availability and pricing, sewer, transportation, roads, and parks).
  2. Measure the impact of converted or demolished housing on current infrastructure.
  3. Measure the potential impacts of not building the proposed building.

This stretch of Milwaukee Avenue had a plan adopted for it in 2008. It would be nice to try and stick to a plan’s recommendations, for once. As far as neighborhood plans go, it is pretty good.

Wanna know what the plan said? Build more housing.

Higher density housing is often attractive for young couples, as well as new families, singles, and empty-nesters looking to downsize their housing units and spend less time on home maintenance and repair. These residents are drawn to urban living because of the goods and services that are available in pedestrian-oriented environments.

Taller buildings would continue the streetwall found along other sections of the Corridor. This would accommodate higher density housing to maximize the number of residents in the area who could conveniently take advantage of the existing transportation and the existing stores, restaurants and services located along the Corridor.

These housing types will help build the immediate population density necessary to create a vibrant and growing Study Area.

I despise this kind of comment from neighborhood organizations: “The density is of major concern for the surrounding residents of the proposed project and is not received favorably.”

How would you feel if someone got to influence the approval process for the place you live now? How would you feel if someone was saying you should live elsewhere? How come people who live in a part of a city get to decide who else can live near them? Why do people say they don’t want to live around a bunch of other people?

Bicyclists in Chicago can travel pretty far in 15 minutes

Mapzen* released Mobility Explorer last week. It is the graphical user interface (GUI) to the Transitland datastore of a lot of the world’s transit schedules and maps.

It also has isochrones, which are more commonly known as “mode sheds”, or the area that you can reach by a specific mode in a specific amount of time.

I wanted to test it quickly to see what these mode sheds say about where I live, a block north of Humboldt Park. From my house, on a bicycle, I can reach the edges of an area that’s 25 square miles in 15 minutes.

Isochrones map of transportation distance from my house

The distance you can travel from my house at the north end of Humboldt Park in 15 minutes by three modes, assuming you leave at 2:21 PM today (in increasing distance/area): Transit (dark purple) Bicycling (burgundy) Driving (pink)

You can request these isochrones through this API call for any location and they’ll be returned as GeoJSON.

I’m still learning how isochrones work, and how they can be adjusted (to account for different rider seeds and route costs or penalties). One difference between bicycling and driving is that the driving area is increased by expressways while the bicycling area has a more uniform shape.

The bike shed is 25.7 square miles, and the driving shed is 52.0 square miles.
