Finding space on the LES

by

CNU has given a few awards to projects which knits new urban fabric into the leftover space around still-standing Modernist spatial objects — effectively finding underutilized “new” space for infill. (This differs from other approaches which remove the offending highway, housing project, etc.) These have included parking lots in Portland, lawns and plazas in Arlington, backyards in Takoma Park, mall ring roads in Columbia, even highway viaducts in Columbus.

I’ve wondered whether a similar approach could be used to heal the wounds that urban renewal left around me, in particular around the CHA senior housing projects that dot many lakefront neighborhoods. Many of these locations plopped open space down where there was — and could once again be — economically productive, vibrant neighborhood fabric, and yet there’s no reason to demolish the existing buildings. And such an approach could yield really big: a UMich graduate studio calculated that new development alongside NYCHA’s Lower East Side projects could accommodate up to 8,000 new apartments, or 22 million square feet of new space — two World Trade Centers or 3.6 Rockefeller Centers worth.

Findings (23 Nov)

Oh, all right, this’ll be another miscellany post.

1. I was reading Sunday’s Frank Rich column on Sarah Palin while walking down Lincoln Avenue — the sadly silenced “German Broadway.” The fiercely nativist, “politically incorrect,” anti-intellectual, non-reality-based far right certainly deserves the moniker “New Know Nothings”

Back in 1855, Chicago’s immigrants electorally vanquished the old Know-Nothings after the Lager Beer Riot. With that, the right-wing elite lost power over the city for centuries — over the right to drink beer. Which of today’s wedge issues is a sure loser for today’s right? Bear in mind that nationally, they ended up winning (and then losing) the war over beer.

2. I ran my new address through the magic new TIF Search. Even though the Fullerton/Milwaukee TIF was only authorized in 2000, it already takes over 2/3 of my tax bill. pie chart

3. Monée Fields-White has a cool profile in Crain’s this week about the Bensidoun public-market operation that’s coming to the C&NW concourse.

4. Hint from Tom Vanderbilt:

One recent study conducted by officials at the Paris Metro—which looked at “missed connection” ads placed by urbanites looking for love in the city—found that the Metro “is without doubt the foremost producer of urban tales about falling in love.” The seats closest to the door, it seemed, offered the best opportunities for falling in love with the proper stranger.

5. I keep meaning to finish off an essay on the parking privatization deal. One of these days…

Spaces (13 Nov)

Coffee bar Originally uploaded by Payton Chung

Star Lounge in Ukrainian Village was built as a bar, but now serves coffee & tea. The bar and counters lining some walls create a nice mix of seating options instead of the usual plethora of half-empty 2-top tables that typify coffee houses; there’s plenty of space for people to work solo or to strike up a conversation. There’s also the communal-table option, but I get a feeling that’ll never really catch on in Chicago. (I do remember one hotel breakfast room in Japan which had communal tables with low dividers — similar to what appears to be called an index table, often seen in library reference areas — which pretty effectively divided the table but not the room.)

Earlier, I’ve posted that walking, cycling, and transit (les modes doux = “sweet modes”) are subject to a positive feedback loop (virtuous circle) as usage grows, while driving creates a negative feedback loop (vicious circle). Now, the quintessential U of C question: but how does it work in theory? David Levinson and Kevin Krizek in Planning for Place and Plexus call these Complementors vs. Competitors. The other pedestrians on the sidewalk are (usually) complementors. The other drivers on the road are competitors. Both of these effects follow from transportation’s network effects, but also result from the peculiar dynamics of automobility vs. other modes — in particular, the very high marginal cost of adding capacity due to the vehicle’s immense demand for space. More compact, space-efficient modes can be scaled up at little cost; and when so scaled they also contribute to the “more is better” positive feedback loop underlying good urbanism.

We do this because

by

A recent conversation turned, as many do, to travel — but not so much the logistics thereof, about which any flyertalker can expound for hours, but rather what it is that we’re seeking away from home. Is it better weather, time with loved ones, a tastier cup of tea, or just that weightless sensation of being lost?

It seems that I like to see the world as a laboratory of urban policies. Untangling and uncovering the layers of human interventions that result in our built environment still interests me more than even the most stunning of natural settings. We can’t understand a decision without understanding the assumptions and the context surrounding it: how the rationales made sense at its moment in space and time. Steve Mouzon likes to repeat the line “we do this because” throughout his pattern books — although that genre typically tells you how to do things and how they’ve always been done, but rarely why. Such practices are meaningless if not grounded in a place and its history.

Similarly, it always troubles (and frankly astonishes) me when I meet small-c conservatives who apparently listened when the Wizard declares, “pay no attention to that man behind the curtain!” To be blind to history, to accept that the world was evidently created just yesterday without any human intervention, to accept that the status quo shall always be such and that any attempts to change are futile, dangerous, and heavy-handed — this attitude strikes me as willful disbelief. When those with libertarian tendencies parrot this, it amounts to (to quote Sondheim) “keep the status quo permanently so!” For instance, I recently had occasion to point out that “making driving ‘as unpleasant as possible’ is no more heavy-handed an intervention than 80 years wherein government strove to make driving as pleasant & easy as possible.” A society’s attitude towards driving has nothing to do with economic freedom, either: by far the two most free economies in the world, Hong Kong and Singapore, have some of the world’s strictest policies discouraging car ownership — punitive registration taxes, high road tolls, and high gas prices. Why? Because they’re also the world’s two most densely urbanized economies, and mass car ownership — and the pollution and congestion that would ensue — would impinge on others’ freedom of movement, and damage the economy besides.

Access road
“It is amazing to go out to the end there, look around, and wonder just why they did this.” (Jack Hartray was speaking of Wacker Drive, pre-Lakeshore East, which resembled this Indiana steel-mill viaduct.)

In the past, I’d study these things more closely here in North America: it’s easier to sell an idea once it’s been tried somewhere with a substantially similar legal or cultural background. Besides, it’s also substantially easier and cheaper to get to. And yet it’s sometimes more interesting to stumble across a great public policy idea implemented amidst greater odds. It’s humbling, for instance, to see carefully built public infrastructure (like TranSantiago’s efficient prepaid bus stops) in countries much poorer than the US, land of the affluent society.

So anyways, here are some highlights from the past few months of wandering about:
– Of course, I walked The High Line in July. It was, indeed, pretty magical to be suspended over the city, but plenty enough’s been written about that.
– I’ve written about Liberties Walk [full set of photos] before, a small-scale pedestrian mall flanked with townhouses over independent shops in scruffy Northern Liberties, Philadelphia. Another, much more ambitious phase recently opened, called the Piazza at Schmidt’s, and the Walk itself has been extended two more blocks. Future phases will add more multistory buildings, notably including one building fronting Girard (an adjacent arterial) with a supermarket and parking. (That phasing strategy is notably offbeat: usually you’d lead with the supermarket anchor to build traffic and then follow up with specialty shops, but this has proceeded in exactly the opposite manner.) The architecture might seem aggressive at first glance, but its weight and massing do strike a balance between industrial buildings on the east and residential on the west. The public spaces themselves are pretty sparse, which works for the narrow Walk but not the broad Piazza. Critics have weighed in on the Piazza, notably Philly Skyline and the Inquirer’s Inga Saffron.
– I’m always intruiged to see other instances where off-street retail has been introduced to an urban neighborhood, so two examples from Santiago de Chile caught my attention: the block-sized Patio Bellavista complex on Pio Nino, and the tiny but elegant Plaza del Paseo Barrio Lastarria.

Where there were no bad schools

by

Well, this is disappointing. I’ve always been proud of the fact that I went to integrated public schools in a Southern inner city — especially since moving up north and seeing the damage that de-facto school segregation wreaks upon city and suburbs alike. What seemed normal as a kid was, as it turned out in my social-policy classes, a national model of how to do the right thing.

The magnet-school system in Raleigh not only provided remarkable education opportunities (my high school offered three orchestral programs, multivariate calculus, and Latin), but left me with enough street smarts to easily and respectfully navigate multiethnic city life. Getting bused across town for school also, in a way, taught me about educational opportunities across the entire city — museums, other libraries, the university. Although half of my peers lived in the lower-income, mostly African American neighborhoods of southeast Raleigh, nearly 90% of us went on to college. All this despite spending some 30% less per student than failing urban schools in the North.

The school system’s strong commitment to integration — suburban and city schools merged long after the courts had shifted away from forced busing — means that there are no bad schools, no schools worth fleeing or closing or “reconstituting,” in a county just shy of one million residents. Indeed, in Raleigh it’s the city schools which are better. This fact arguably played a huge role in making Raleigh one of the best-educated, most prosperous, fastest-growing cities in America:

For comparison’s sake, imagine that instead of merging in 1976, the Raleigh and Wake school systems had continued to be separate. And not only that, but Raleigh was one school district and every other town in Wake County had a separate school district of its own, like Wayne County [suburban Detroit]. Would Raleigh today be affluent? Or would the affluent people of Raleigh have long since moved to Cary, Apex and the rest of the suburbs, leaving a poor inner-city school system behind? [Bob Geary, Independent Weekly, writing about Gerald Grant’s new book Hope and Despair in the American City: Why There Are No Bad Schools in Raleigh]

And yet there are others who inexplicably see such policies as failures, who insist that geography should be destiny. A small minority, likely drawn to Raleigh by its reputation for great schools, has consistently railed about the constant churn of school reassignments — necessary for a district that opens several costly new schools every single year. Maintaining integration has become more difficult as sprawl marched farther afield and as patterns of socioeconomic segregation ossified. (In this regard, the spread of suburban poverty and inner-city gentrification have actually helped to maintain some integration.) The usual right-wing hue and cry over “socialist social engineering” (never mind the right’s continual insistence on deeply interfering with private lives) becomes double-speak for perpetuating segregation. One school board member wants to have his cake and eat it, too — disband the magnets and somehow offer their programs at every single school, while decrying the “high cost” of busing. (Is there demand for AP Latin at every school? Even if there were, who could afford it?) Yet busing costs much less than trying to rescue failed schools with vast infusions of cash.

I’m only writing about this since, of course, the fringe has won a crucial battle: apparent control over the Wake County school board. NC Policy Watch argues that only 3% of voters — just over half, largely in the suburbs, in a poorly attended election — have come to dominate the debate, and that the considerable achievements should be better marketed; “the school system itself could do a better a job telling its impressive story and acknowledging the work it must do to address its problems.” I can only hope from afar that Wake County doesn’t turn its back on one of its few progressive policy achievements.

Easy street reclamation

by



Reclaimed street stub Originally uploaded by Payton Chung

The WPB plan calls for reclaiming street space along Wood and Hermitage, little stub-end streets on the 1300 block of N. Milwaukee that were cut off by the subway trench. They’re “the big empty streets to nowhere,” as the plan calls them, and their purpose could be served by just a single lane of traffic. (A similar opportunity exists at Milwaukee & Diversey.)

Here’s an example of how a similar street, off Washington Ave. in downtown St. Louis, was reclaimed through the simple addition of some planters. In theory, a car could still drive through here for emergency access, about where the people are standing. An even cheaper option — the ECObox temporary garden in Paris, built by ringing the site with discarded wooden pallets and backfilling with dirt — is profiled in the cool “Actions: What You Can Do With the City” exhibit up at the Graham Foundation right now.

Two other cool things I noted at the exhibit:
– The emotion map, which is kinda what happens when mood rings meet GPS and GIS. It locates “areas of communal arousal.”
– From Atelier Bow-Wow and firmly in the vein of chindogu, an idea for the “left bike battery charger”: that passerby could ride parked bicycles to feed electricity into their devices’ batteries. Maybe the “green gym” could offer such a service as an incentive for people to stop in and recharge daily.

“Scofflaws?” Scoff.

by

Something else, posted as comment on Chris Swope’s Urban Notebook, in the vein of several other posts:

Traffic rules as we know them weren’t codified until car traffic overran cities in the 1920s, and even then were created to prevent cars from running over everything else. If the intent of a stop sign is to keep traffic from speeding through an urban neighborhood, then any 10MPH cyclist is observing the intent of that law even if she doesn’t follow the letter of the law. (Not that drivers do, either: stings here in Chicago found 80% speeding through school zones and almost none yielding at crosswalks.)

Cyclists in Amsterdam or Copenhagen get not just bikeways, but also a completely different set of road rules tailored around cyclists — even green lights are timed to move bike, not car, traffic. Actual full stops are relatively rare; instead, signs oblige vehicles to yield. Yet both driving and cycling there are much safer than in the US.

This “yield if it’s safe” approach exists in North America: in Idaho, cyclists may treat stop signs as yield signs; in British Columbia, pedestrians and cyclists may treat flashing-green stoplights as stop signs; and in Portland, stops have been replaced with yields along 100 miles of “bike boulevards.” These acknowledge that a full stop for a cyclist isn’t like tapping the brake pedal in a car, since the car wields 500X as much horsepower (and thus deadly force). It’s more like demanding that drivers stop, shift to park, engage the parking brake, turn off the ignition, remove the key, and start up again. It’s akin to asking pedestrians to sit down before getting back up and crossing the street.

Instead of more enforcement, better laws would go a long way towards improving safe and orderly traffic flow for everyone.

Edit: Here’s an interesting intervention. Installing a “bike scramble” at one intersection in PDX increased cyclist compliance with the signal from 21.9% to 95.8%. [PSU study, h/t Twin City Sidewalks]

Off-Milwaukee: a bike route

by

Everybody loves Milwaukee Avenue — perhaps a little too much so. It’s the city’s busiest on-street bicycle route, with a bicyclist passing through Milwaukee, North, and Damen every six seconds during rush hour. 2009 counts indicate over 3000 a day (about 22% of all vehicles) at its southern end, a number that’s boomed in recent years. Besides all these bikes, it moves 15,000 cars and buses a day, and 70,000 passengers ride alongside on the O’Hare Blue Line.

It’s certainly the most direct route between the northwest side and downtown, but sometimes we cyclists want a route that involves less door zone and more trees. So, after years of living in Ukrainian Village, Wicker Park-Bucktown, and Logan Square, here’s one set of lightly trafficked routes which get me to and from downtown with minimum fuss (and often with stoplights as it crosses arterials). It’s 36% longer than a straight shot down Milwaukee from Logan Square to Wells/Monroe (22.7km vs 16.7km) and takes about 10 minutes longer.

route map

[A zoomable, turn-by-turn route can be found at Bikely.]

The route takes advantage of a few streets around Logan Square that were platted around Milwaukee’s diagonal axis, evidently before the gridiron was enforced. It also runs along the grid through scenic Ukrainian Village and the Kinzie-Carroll-Fulton industrial corridor on the near west side. For those times when a stop on the north side is necessary, I’ve found Kingsbury and Larrabee-Geneva to be good routes.

How can these streets become even better for bikes and for their residents? One approach, popular on the West Coast (and in the WPB plan!), is called the bicycle boulevard — radically traffic-calmed side streets that are optimized for bicyclists moving at a steady 10-15 MPH. They’re the mainstay of the bikeway networks in cities like Berkeley, Portland, and Vancouver, and take full advantage of the fact that Western cities have extensive street grids with good connectivity. Although they’re a key element of Chicago’s Bike 2015 Plan, none have been implemented yet here. When they are, there’s plenty of guidance out there, like this new Bicycle Boulevard Guidebook. Local residents get calmer traffic with fewer inconveniences, cyclists get faster and better routes, and everyone wins with more safety — similar interventions in Europe have resulted in 50% reductions in injuries.

A few of the elements found along bicycle boulevards:

chicane
Traffic calming features like chicanes (twisting the path of vehicle traffic, often using planting or curbside parking) and low speed humps.

Bicycle boulevard entrance
Cut-out sleeves and other curb features allowing bikes to go two ways on a street, but restricting car traffic to one-way or altogether. (This simple feature, already implemented by Dearborn Park in the South Loop after years of effort, could make a lot of the new culs-de-sac around town much easier on bikes.)

stop
Bicycle-friendly traffic signals give cyclists and pedestrians a protected way to continue where the bike boulevard crosses arterial streets. In some cities, like Brookline, Mass. and Davis, Calif., these are embedded sensors in the street; in other cities, like Vancouver (shown above), they’re pushbuttons by the road.

This still leaves the question of how to further improve Milwaukee Avenue for the thousands of cyclists who use it every day. After investing millions into the city’s busiest bike route, the Lakefront Path, some more attention should be paid to the city’s busiest inland bike route. Many incremental, and relatively cheap, improvements would improve bikeability on this street — improving safety for all users and further encouraging cycling’s amazing growth. A few relatively low-cost but high-impact ideas:
1. Perhaps there are enough cyclists — roughly half of peak-hour traffic, by some accounts — to justify creating timing the green lights so that bikes and other traffic at 12MPH gets a “green wave.” This has also been done in Denmark, downtown Portland, and San Francisco. I can never seem to hit the green lights in sequence, regardless of my speed; enhanced signal timing could speed the trip from Logan Square to Wicker Park by 25%. The “wave” improves safety by moving cyclists through intersections, which is where where conflicts and crashes occur, and by improving compliance with the law. (The usual argument against, particularly for CMAQ funds, is that the air quality benefits of encouraging bicycling rarely cancels out the AQ impacts of stopping cars/trucks, but perhaps we’ve reached a level of cycling where the balance has tipped into the bikes’ favor.)

2. At particularly complex intersections, a Leading Pedestrian Interval could dramatically improve pedestrian and cyclist safety. An LPI gives pedestrians a three-second head start over cars at an intersection (often used by bikes, but this could also be explicit), giving peds clear priority over turning vehicles. It’s like a mini-scramble signal, and it’s incredibly effective: a test in St. Petersburg, Fla. found conflicts diminished by 95%. The six-corner intersections have lots of turning movements and thus many conflicts; they’re also perhaps not best for scrambles, since few pedestrians would wait through the entire cycle to cross the street.

3. Speaking of turns, I would suggest that the protected left-turn signal phases (which I generally dislike: there’s no right to a left turn!) follow, not lead, the green phases. (Here’s another argument for it.) In other words, the left-arrow-green should come after the green light — which is, after all, usually when people sneak a left anyways (after getting stranded in the middle of the intersection by the “left turn trap“). Also, too often it seems that the drivers waiting in the left turn lane get distracted and don’t make their turns until their protected signal phase is almost over, which wastes precious signal time for everyone; this should be less of a problem with a trailing signal phase. Apparently, this is called “lag-lag (permissive-protected) left-turn phasing” in the traffic engineering literature, and I should probably ask a few engineers about it.

The above three signaling improvements could easily be accomplished within the scope of the upcoming Milwaukee Avenue reconstruction program, or even before. Perhaps they could together be called “Greenlight Milwaukee.”

4. I was going to write something about how more radical bike lane designs could revolutionize the way the street works and looks. Rue Rachel across Montréal’s Plateau, fits a bidirectional cycletrack, two-way traffic, and parallel parking into a ROW that could easily fit inside Milwaukee Avenue with ~10′ to spare, and these streets in NYC have protected bike lanes in streets with even less space and higher traffic volumes to work with. However, such approaches are impossible until the parking-meter contract ends; there’s no way to add much new bike space (or bus space, or pedestrian space) without subtracting at least some parking spaces. Oh well. File this one for the 2083 file.

In the meantime, the WPB plan offers up schemes for reclaiming excess road space at key intersections, which would slow down car traffic and make pedestrian crossings shorter and safer.

5. A while ago, I thought I saw a schematic plan for Logan Square which showed narrower roads, fewer crossings, and tighter curb radii, but I can’t seem to find it. It’s crazy that crossing the square requires crossing 20 lanes of 50MPH traffic at six different lights. There’s no reason whatsoever for the two-lane roads approaching the square to become four or six lanes through the square; the excess pavement could be returned as green space. In the future, the urban-fabric wounds left by the subway tunnel (the space over the portal, the principal subway entrance and the huge blank wall behind it, the underutilized former terminal [now Banco Popular and its parking lot], and the bus terminal) can be healed with new buildings or public amenities.

Smarter shuttles for Silicon Valley

by

The rise of Silicon Valley employee shuttles has been much covered by the press — with some finding solace in the fact that they grant an urban, car-light lifestyle option to formerly office-campus-bound techies. Since these are operated by private employers as an employee courtesy, they’re usually comfortable and sometimes have sophisticated IT backends that make them more demand-responsive than public transit options. A few disappointments, though:

1. They’re not quite the IT revolution we were promised, although that could certainly change. Given that all the users are well-wired (erm, well-wirelessed?) and that origins and destinations are relatively closely clustered together, this is one population that could conceivably pilot a fully demand responsive “smart jitney” system. Yet instead, fixed route buses (and all the wasted capacity they entail, especially with each company offering its own service) appear to be what even the savviest of techies are comfortable with.
2. The shuttles add even more layers of complexity to what’s already a mind-bendingly complicated transit network. I’m the sort of guy who loves figuring out puzzles, and again IT can do a lot to help sort out complex equations like “getting from A to B” — but Bay Area 511 already has to keep track of 41 different transit agencies. I remember one afternoon excursion, with two destinations, which sent me on six different agencies’ vehicles — each with different fares, transfer policies, hours of operation, whatever.
3. Their emergence really points up the failure of the last-mile solutions, in SF and particularly in the Valley. Muni is a poor crosstown solution to get to CalTrain, whose corridor is not particularly close to many trip origins. And in the Valley, auto-oriented development patterns make that last mile utterly impossible. It’s telling that (just to choose one example from biotech) Genentech’s South San Francisco facility is hidden in an office park 4000′ from a CalTrain commuter rail station, while its Cambridge University Park facility is a pleasant 1000′ walk from an MBTA rapid transit line.

In short: Silicon Valley needs to grow up at some point. Perhaps nowhere else in America is there a more clearly demonstrated need for transit-oriented development.

Good press

by

1. Good press stunt: the Maldives held an underwater cabinet meeting. They’ll need to learn how to do that more often, since I’ll probably outlive the Maldives: at the rate we’re going, their islands will be inundated by rising seas in a few decades. The cabinet ratified a statement urging rapid global reductions in greenhouse gas emissions — an SOS to be presented at COP15 in December.

2. Good coverage: there is a kind of awesome article in Crain’s this week by David Sterrett about the market for electric hand dryers, formerly controlled by Berkeley, Ill.-based World Dryer. Some choice phrases: “the local company that’s dominated the industry since its inception is seeing new business slip through its slightly damp fingers… dryer-industry arriviste Sir James Dyson… Timothy Griffin, acting village administrator, [says] ‘People have nothing to do when drying their hands, so they read the label and see Berkeley.’ ”

(I’ve tried to avoid paper towels since a visit to Japan, where they’re nonexistent. Some restrooms have hand dryers — often the Mitsubishi Jet Towel — but the general assumption is that you bring your own cloth towel.)

3. Not covered at all: among global scientific bodies, it’s not just IPCC (politically tainted by that Nobel Peace Prize!) that’s come to a consensus that we humans have royally changed the climate. In fact, the Stratigraphy Commission of the Geological Society of London states that we’ve actually managed to shape the vastness of geologic time by ushering in the Anthropocene, per a report from Mike Davis.

Of course, this being Davis, there’s a mention of slums: “While guests enjoy the $5,000 per night rooms in Burj Al-Arab, Dubai’s celebrated sail-shaped hotel, working-class Cairenes riot in the streets over the unaffordable price of bread.” There’s also the transmutation of said slums into a cynical, Blade Runner apocalypse:

Coordinated global action on their behalf thus presupposes either their revolutionary empowerment (a scenario not considered by the IPCC) or the transmutation of the self-interest of rich countries and classes into an enlightened ‘solidarity’ without precedent in history. From a rational-actor perspective, the latter outcome only seems realistic if it can be shown that privileged groups possess no preferential ‘exit’ option, that internationalist public opinion drives policymaking in key countries, and that greenhouse gas mitigation could be achieved without major sacrifices in upscale Northern Hemispheric standards of living — none of which seems highly likely. And what if growing environmental and social turbulence, instead of galvanizing heroic innovation and international cooperation, simply drive elite publics into even more frenzied attempts to wall themselves off from the rest of humanity?… We’re talking here of the prospect of creating green and gated oases of permanent affluence on an otherwise stricken planet…

Will the electorates of the wealthy nations shed their current bigotry and walled borders to admit refugees from predicted epicenters of drought and desertification like the Maghreb, Mexico, Ethiopia, and Pakistan? Will Americans, the most miserly people when measured by per capita foreign aid, be willing to tax themselves to help relocate the millions likely to be flooded out of densely settled, mega-delta regions like Bangladesh?
