A New Edgewater Library and Parking Lot


How many meetings have you been to in order to have your concerns about the new Edgewater Library heard? None I bet. Do you even care? Do you know that a 98 year old building will be torn down for a parking lot and that the curb will be cut for a driveway across the Broadway sidewalk?

Lets face it most of us rarely use the library. So if the library is taken off line for a year or so we won't really notice nor be inconvenienced. But we actually do care. Water, Police, Fire, Roads, Schools, Parks and then Libraries. It may be at the bottom of many lists of most important government services, but at the same time it represents a very important marker of the quality of our social culture.

It represents something about us and our society, that if lost, would represent a loss of progress, a regression, a reversion backwards towards a darker age. So we really do care.

So the library is important. But how about the building? Again what do we care? We're getting a new building, hoorah! That's great. New is better, right? Yes, often.

But I get it. Few of us really care about the mundane details of library design nor the urban impacts of a new building on our streets and community.

Yet on the other hand there are some who care greatly. Indeed they actually care about every little detail. Sometimes every detail about everything that goes on in their community. You meet them at a party and when you've heard enough you move on. Maybe at the next party you arrange your movements to minimize the length of your conversation with them. Sure you're glad they care, and sure you're especially glad that they seem to have the energy and interest to try to get their opinions heard by the powers that be that actually make all the detail decisions that go into something like a new library.

So how many meetings would a person super interested in every and all community details have attended about the library by now?

None? Really none?

We know our government is not representing us when they can't take the time and effort to listen to us. The problem for our governments is that listening is hard. Or maybe it's hearing that's hard. Whatever. It's like a constant party where there is one person after another waiting to talk to you about their interests.

But then that is their job. They are paid to listen.

So without any formal meetings with the community, ground has already been "broken" with a golden shovel for the new Edgewater Library. The plans are drawn and a 98 year old building is about to be torn down and the curb cut for cars to cross the sidewalk to another parking lot on a stretch of Broadway already loaded with too many parking lots. A stretch of Broadway that is served by a bus line and two el stops within a half mile.

Let me say simply that neither action is good urban design. Let me say simply further that not involving the community in the design process is not good government process. Above is a picture of one more bit of a historic neighborhood never to be recovered. You can't build new hundred year old buildings.

CTA Frequency Map - Wait Time Comparisons


Jarrett Walker has expressed interest in what I am doing. He may want to link to my work. I will need to choose to suggest that he link either at PrairieStateBlue or my little used personal blog Edgewater Observer. If you have thoughts about my choice please comment. Here is my latest work. It is a comparison of different possible wait times. It has a built in legend so it should be self explanatory.



CTA Frequency Map Version 9 - Ten Minute Service Circles

(Update: Oops. I am supposed to say something like: Images derived from Data Provided by The Chicago Transit Authority.)

Here are some images of version 09. In this version I have overlaid an earlier version where line widths represent the number 0f trips a week, fatter being more trips, with the ten minute or better circles from version 08.

The 79th street bus still shows that it is the major southside east west corridor. To my lay mind it still screams BRT! I'm going to have to take a trip soon and eyeball that street fr0m end to end.

The whole system map is not as large nor clear an image as I'd like. The other images show the northside and the loop area. The loop would take special treatment for a professional version, imho.

CTA Frequency Map V8

(Update: Oops. I am supposed to say something like: Images derived from Data Provided by The Chicago Transit Authority.)

I'm using this space as a bit of a shared workspace. So forgive the lack of relevance to the normal postings to this blog.

CTA Frequency v8 - Frequency Via Stops

Click to enlarge.

This is a work in porgress. This particular version is more a proof of concept. Here is what Mr. Walker had to say about my previous version:

Jeff. Thanks! I object, though, to using trips/day as a proxy for frequency, because lines with really intense peak service can have lots of trips/day even with little or no all-day service. . If the point of a frequency map is to show people the network they can travel on without waiting long, it needs to be based on actual midday headway. Cheers, Jarrett

So I asked for some help in coming up with "actual midday headway" thusly:

So if I am to do a midday headway map, I suppose counting the number of trips that leave between 11:30am and 12:30pm would not do because they might send out a bunch of drivers at 11:35 all together and then no more until 12:50 when another bunch might be sent out? So is actual midday headway the time between the first trip nearest noon and the one after that? Forgive my ignorance, this is not an area of expertise, but what is a good mechanism for measuring "midday headway?" What would be a good method of calculation?

To which he replied:

Jeff. You're right, it's tricky!

You have to return to the spirit of Frequent service, and the wholereason that we're mapping it. We want people to see where they can travel ALL DAY without waiting very long.

So the real question is: "What is the longest scheduled gap between consecutive buses anytime during the midday?" The point of frequent service is that it's a guarantee, not an average., That means we are mapping the worst case, not the average case.

Jarrett

While working with the previous version I learned that "Shapes" provided by the CTA were not properties of "Routes" but rather "Trips." In producing this map I further came to realize that "frequencies," or goal here, is also not a property of Routes nor Trips, but rather a property of "Stops".

So using the largest table provided by the CTA, the "Stop Times" table of over two milion separate records, I created a new table that not only provided the time of arrival at each stop but also the time of the previous arrival at that stop. I then calculated the greatest time difference between arrivals between seven AM and seven PM for each stop. I then drew a circle for each stop with larger circles meaning more frequency, or less maximum times between stops. The variance in circle sizes above represent a range of maximum scheduled wait time from seven or eight minutes to thirty or more minutes. Remember that's worse case scenario. I used the same color scheme from the previous map, red and orange buses, green for el/subway and blue for express bus service.

There is a ton of possible tweaking. This is a work in progress. Be patient. I'm trying to be frequent in my updates.

Parisifiing Chicago - Peterson Ave. BRT (Bus Rapid Transit)


Chicago has a very good rail rapid transit system. But not great. Great is Paris and London for example. Here's Paris' Metro in black with Chicago's CTA overlaid in red at the same scale. These are all subway and el lines for both cities. Since I am (just) a simple northsider I centered Paris on the north and west sides. Those are the parts of the city I know best (but I am actually familiar with parts of the south side other than Comiskey and Hyde Park.

Paris is pretty compact, at least the central part absent the suburbs, isn't it. It's also very dense population wise. The streets are narrow and the there are rarely front yards and many buildings are 4 to 7 stories high.

The thing is Edgewater has similar density. Yet all we have is a single CTA line. Which is probably about right as practically everywhere in Edgewater is within three quarters of a mile of an el stop. And much if it is within a half mile. Unfortunately there are only two ways to go, north or south. Granted that's two out of three possibilities. But the next connection to any other direction is miles away, to Ravenswood at Belmont and to Skokie at Howard.

There is a serious flaw in both Chicago's future transit planning and indeed the nation's. The flaw is that extensions and new lines are planned into areas that have no rail rapid transit service rather than in the areas that have it. Why is that a flaw? Because the greatest users of transit are those where the transit exists and where the urban densities exist to support rapid transit.

Well, of course, you reply if there is no transit then how can you use it at all? And that's a valid question absent the second caveat of where urban densities exist to support it. And yes there is some validity to build it and they will come, but that does not refute the point that we in Chicago where urban densities are appropriate still need more and better rapid transit.

Let me pose a question to Edgewaterites. Have you ever taken public transit from O'Hare to Edgewater? Wasn't pretty was it? Your choices are to go all the way downtown and then all the way back to Edgewater or transfer to a Lawrence or Foster bus at Jefferson Park and then back again onto the el.

We, and much of the lakefront, need west traveling rapid transit. The operative word here is rapid. Rapid means two things: one, faster than car traffic and two, frequent arrivals.

Car traffic brings up another important issue that Edgewater faces; namely too much car traffic. We live in the middle of a major car traffic flow and bottleneck from/to the north and west and all headed to or from the loop. It used to be loop rush hour determined but during the last twenty years it has been changing into a more equalized flow in each direction. It was so extreme before that lane reversals on Sheridan and Ridge would dedicate three lanes one way and one the other depending on whether the flow was in or out.

One of the major changes by the Aldermen of Edgewater was the elimination of those lane dedications. I wasn't involved in the decision making process but I bet the divisions and arguments for and against were similar to those going on now as concerns the return of non-rush hour parking onto Ridge between Clark and Broadway. Those opposed are concerned that traffic backups within the Edgewater neighborhood will cause sufficient frustration that drivers will begin short cutting through the residential streets. It is not a paranoid fear. It could happen even with the speed humped nature of many of our residential streets.

Actually, a rapid transit line running out Peterson Street west from the Bryn Mawr Redline station would likely soak up enough car traffic to obviate making the bottleneck any worse than it is now and therefore prevent attempts of residential shortcutting. If the line were to connect with the Jefferson Park Tansit Hub it would also create a connection to the Airport from Edgewater and even Evanston. Again the key word is "rapid": rapid in speed and rapid in arrival.

The current fad in urban rapid transit is light rail. Light rail used to be called street cars or trollies. Indeed the street car system of 1947 delivered a similar density that the Paris Metro does today. In the above map for the north half of Chicago, red are streetcar lines while blue are electric trolley buses. The other colors are diesel buses.

Streetcars gave way to buses as car congestion grew to the point that they were no more rapid, and indeed often less rapid than cars. The other issue with light rail and even street cars today is expense. They cost way too much to build, especially for a system that turns out to not be rapid.

There is a way to make streetcars faster and even faster than cars. The major way is dedicated rights of way where cars are not allowed while the minor way is to give them control over stop lights. Usually the right of way is in the center of the street with dedicated "stations" for riders in the middle of the street as well. Think of the Illinois Central line on the south side where it crosses Stony Island. So with widely separated stations and dedicated rights of way and control of stop lights street cars can go faster than cars and thus approach if not actually succeed at becoming rapid.

But here's the thing. If you do those things for buses, then they can become rapid as well. And not only cost less but be more flexible as well. You can have regular bus lines that can serve neighborhoods locally and then run express as they merge into the Bus Rapid Transit right of way.

And that is exactly what I would propose for Peterson Ave. Only I would take it a step farther and have it get onto LSD for express runs downtown. That's what many northwest siders are doing anyway and it is those people we want off of Ridge. Only now not for parking but for dedicated BRT lanes (in the middle not the edges of the street.)

Between Broadway and Sheridan the BRT might have to share the road with cars but that is a short distance and easily managed especially with the buses having control of the stoplights.

Another candidate for a BRT, I would argue, is Western Ave. For a while (maybe still) Western had express buses that only stopped at the major streets. I road one of those once during rush hour and it was pathetic. I rode from about Montrose to the Blue line at Milwaukee and Armitage. I think we may have beaten the local bus but it was just barely. One beauty of a Western BRT is that it can link up so many of the northwest and western el lines. Probably the same could be done with Cicero. I have already sent the Peterson Ave BRT down Cicero to get to the Jefferson Park Transit Hub, might as well go whole hog. And as long as we are going whole hog we throw Irving Park into the mix too. Petty soon we are approaching a rapid transit density comparable to Paris.

Let me end this post by recommending this remarkable blog whose primary focus is Bus Rapid Transit. It's http://www.humantransit.org/ After I was referred to it I found myself reading post after post in a single setting. Needless to say I highly recommend it.

Historic Preservation Battle Now In Progress in Edgewater, Chicago

Historic buildings are the urban equivalent of wilderness. There is only so much and once it's gone it's gone forever.

I have become aware of two recent issues of conflict surrounding Edgewater historic preservation. A minor one on the south-west corner of Broadway and Hollywood and a major fight between the Edgewater Historic Society (EHS) and well what appear to be ideological opponents to preservation. After a meta-discussion I will give my take on these two specific fights.

I'm all for progress. Indeed I call myself a progressive.

Some buildings are ugly and boring. At least that's the subjective judgment of the moment.

And we haven't even gotten to American Hot Button issue of "private property". I do not believe in absolute private property. I believe in limits to private property. Indeed when the U.S. banned the ownership of human beings, we set the most important constitutional limit on private property. Personally I am willing to extend that limit much much further.

I believe in imminent domain. It is the rule of law that mediates disputes between community and individual claim to property. Some people today have extreme ideological beliefs as well as strong emotional attachments to a notions of private property that border on the absolute. My own extreme ideological beliefs and strong emotions tend in the opposite direction. I got over those, however, in my youth. Yes I still believe that Gates and Shell oil claim obscene and improper amounts of "private property", but I doubt that the richest person in Edgewater would raise my ire. And I would not be surprised if there is someone worth hundreds of millions of dollars in Edgewater.

But I am willing to put my money where my mouth is. As the first step in preserving buildings I am willing, with a community vote, to waive either all or any percentage of property taxes for designated buildings.

But would I be willing to donate from my own after-tax personal funds to an entity of community ownership to save such buildings? No. That's what we have governments for. That's why we have courts to decide a reasonable compensation that balances the common good and the individual good. That's why elect representatives and urge them to make the hard decisions that split community sentiment.

Remember there are three sides here: the community who lives here, who loves the historic and diverse nature of Edgewater; the current owner ready to cash out their home or business in a neighborhood where they loved experiencing, day to day, the historic and diverse nature of Edgewater; and the future profiteer (they will make a profit, no?) who will tout the very things that they will be destroying, the historical and diverse nature of Edgewater.

So our job is simple. Support preservation and let our democratic republican councils and courts make the hard decisions of what is fair. That's what you do when both sides have conflicting "rights".

I'm saving for the next post the collected emails on the subject.

Prairie State Blue

We've changed the name of SoapBlox/Chicago. It's now PrairieStateBlue. Still the same great bunch of progressive political activists scattered around Illinois and N. Indiana.

I don't know why you've come here, but for the moment I recommend that you get on over to PrairieStateBlue.

5440 or Fight

I'm sure someone has used the title already, but I haven't seen it yet myself.

That's 5440 Sheridan and it should really be 5440 and fight.

At the moment I would abstain on voting on this. I don't know enough and I support the notion of local say on projects like this. I know we in the northwest quadrant of the ward have suffered votes by folks in the rest of the ward that voted against us when they should have abstained.

So let me point you to this blog where the blogger does a great job telling you who's for it and who's against it, but doesn't quite explain the cons as well as they should, since they appear to be against it.

The blog is Edgewater Chicago Surreal.
