Seoul going for its own High Line: the Skygarden to use an old elevated highway

Posted on by

The High Line concept is spreading around the world: Seoul is now making plans for the Skygarden.

Like the High Line, the Skygarden will make good use of unused infrastructure: the Seoul Station Overpass hasn’t seen traffic since 2009, when it failed a government safety inspection. Unlike the High Line, the Skygarden is part of a more expansive government-led initiative to make Seoul’s built landscape greener and more walkable. “The mayor of Seoul is quite active in establishing an improved architectural climate in the city,” says Winy Maas, MVRDV’s lead on the project. Last fall, Seoul’s mayor, Park Won-soon, hired architect Seung H-Sang to be lead the change as first “city architect,” a job that involves supervising a team of urban planners, researchers, and designers, as well as overseeing public projects like the competition for Skygarden. Construction should begin in October, and the park is expected to be completed in 2017.

MVRDV’s design scales over time, spilling over into other parts of the city. Skygarden will function as a nursery to a bevy of trees that will eventually be transplanted to several rooftop gardens town. The architects plan to build out satellite gardens within a radius of about 800 feet, and then expand another 800 feet about a year later. In total, the pedestrian park will be home to 254 species of flora, which Maas calls “a complete collection of Korean vegetation.” His project will continue the Korean tradition of clipping, cutting, and arranging lush landscapes in precise ways. “It’s a very specific culture that doesn’t exist in other places,” he says.

Reaching the same success of New York’s High Line may not be easy to do. Public spaces or parks don’t automatically become popular just because they have been constructed. The High Line helped revitalize an area but there was already a good amount of foot traffic nearby. As Jane Jacobs would suggest, successful parks require a steady flow of people in and out in order to provide an interesting scene as well as ensure safety. So, in this case in Seoul, the context of this new park matters as well as the fact that it will be an interesting nursery. Are there other nearby uses that help ensure a steady flow of people? Is there land nearby with a mix of uses and/or development potential? Does the fact that this used to be a highway help increase the cool factor (the High Line is fairly narrow but a highway would be wider and could provide for some other uses – plus, removing highways might actually help traffic flow)?

Paying for Austin’s permitting backlog which may be partly due to its McMansion ordinance

Posted on by

Several years ago, Austin enacted an ordinance intended to reign in McMansions. But, that ordinance may have contributed to a backlog of permits which the city is now trying to tackle:

The directors of the city’s planning and permitting departments estimate it would take $400,000 to hire temporary workers and pay for overtime to eliminate the current backlog in the next 90 days…

Next year the department plans to ask for $1.6 million in additional money to fund 11 new positions. This memo comes as the city is just launching its annual budget process. Over the next few weeks, every department is going to be compiling a budget wish list, which eventually is sent to the City Council…

Some of the blame for the three-week delay in residential planning and permitting was placed on the “complexity” of the city’s McMansion ordinance, which limits housing sizes in certain neighborhoods. “As such the department will recommend changes to the (land development code) that will simplify the McMansion provisions and will extend turnaround times for those types of reviews to ensure that there is sufficient time to perform a thorough review,” the memo states.

The planning and permitting departments, which used to be one department called Planning and Development Review, are responsible for approving all real estate development in the city, from housing remodels to new subdivisions.

It can take some time to see how ordinances actually play out and perhaps the initial ordinance can be “smoothed out” for this sort of process. Communities can also run into this problem if they have high rates of growth. Austin is a desirable place for construction so it may make sense that it has a lot of permits to deal with.

I wonder how much these decisions to speed up the permitting process are driven by builders and developers who generally want to move as quickly as possible. If there is a bit of a delay in the process, would these builders actually cancel their projects or go elsewhere? Builders and developers are often powerful and are viewed as important harbingers of economic growth. Yet, isn’t Austin so desirable that a delay won’t harm things much? Granted, lots of people might want more efficient government but that also may just require more government employees.

Wheaton’s walkable shopping center…surrounded by parking lots

Posted on by

Renovations are coming to the Town Square Wheaton shopping center yet the picture of the complex shows it may just be as auto dependent as any shopping center:

It features 160,000 square feet of retail space, much of it filled with chain stores such as Banana Republic, Gap, Joseph A. Bank, Starbucks, Yankee Candle and Talbot’s. The property also includes two professional buildings that house medical offices.

Tucker Development plans to enhance the seven buildings arranged in a walkable loop primarily through signage and facade improvements.

Town Square Wheaton, a shopping center on the south side of the city, recently was sold for nearly $57.3 million. The new owner, Tucker Development, has plans for $1 million in renovations.

This shopping center embodies a lot of the features of newer lifestyle centers or New Urbanism-inspired shopping centers: it features a central plaza with a walkable loop around it, the scale is not huge, there are office spaces on the second floor plus numerous eateries (mixed uses), and it borrows from a local architectural style (Prairie School).

Yet, the overhead view highlights one of the problems that plagues numerous New Urbanist developments: they are often plopped right into car-dependent areas so that even if they are pleasantly walkable, one needs to drive there first. Walking or biking there is not easy; there are apartments adjacent to the center but there is not a permeable boundary between the spaces. You could walk or bike to the center from several nearby single-family home subdivisions (I was just biking near here recently) but that typically requires traveling along and/or crossing busy Naperville Road which funnels a lot of commuter traffic through south Wheaton (the primary path to Naperville and I-88) and isn’t exactly lined with beautiful structures.

Hence, just another shopping center surrounded by parking lots…

Boom in skyscraper construction may mean less light for city residents

Posted on by

New skyscrapers add to a city’s skyline and help boost its prestige. But, those same buildings can block light and this is an ongoing concern in New York City and several other major American cities.

For cities, shadows present both a technical challenge — one that can be modeled in 3-D and measured in “theoretical annual sunlight hours” lost — and an ethereal one. They change the feel of space and the value of property in ways that are hard to define. They’re a stark reminder that the new growth needed in healthy cities can come at the expense of people already living there. And in some ways, shadows even turn light into another medium of inequality — a resource that can be bought by the wealthy, eclipsed from the poor.

These tensions are rising with the scale of new development in many cities. As New York’s skyscrapers set height records, Mayor Bill de Blasio has also proposed building 80,000 units of affordable housing over the next 10 years, much of which the city would find room for by rezoning land to build higher. Boston wants to find space for an additional 53,000 units. Toronto in the last five years has built more than 67,000. All of which will inevitably mean more shadow — or even shadows cast upon shadow, creating places that are darker still…

In New York, legislation was introduced in the city council this spring that would create a task force scrutinizing shadows on public parks. Lawmakers in Boston in the last few years have repeatedly proposed to ban new shadows on parkland, though they haven’t succeeded. In San Francisco, the city has tightened guidance on a long-standing law regulating shadows in an era of increasingly contentious development fights. In Washington, where the conflict arises not from luxury skyscrapers but modest apartments and rowhouse pop-ups, the zoning commission voted in April on rules that would prohibit new shadows cast on neighboring solar panels…

As a result, multimillion-dollar apartments in the sky will darken parts of the park [Central Park] a mile away. Enjoyment of the park while actually in the park — a notably free activity in a high-cost city — will be dimmed a little to give millionaires and billionaires views of it from above.

This is an ongoing issue, one that helped prompt zoning laws in the first place and still gets at the basic question of whose city is it anyway? I’m reminded of the suggestion from New Urbanists that there is a proper ratio of building height to the street in order to limit this issue (and also boost street life rather than dwarf it – this is a whole other issue that parts of Manhattan could deal with) but in places where land is incredibly valuable – New York City, Hong Kong, Tokyo, etc. – these design guidelines don’t satisfy the interest in density and the money that can be made.

One drastic thought: shouldn’t all tall buildings in American cities be oriented to the north of major streets or parks or features so as to limit shadows? This is a problem with Central Park: if the tall development was mainly to the east or north, the shadows wouldn’t be as much of an issue (though they would fall elsewhere). Yet, settlement patterns didn’t originally occur with these guidelines in mind.

Summarizing 25 years of researching the lives of 790 Baltimore kids

Posted on by

Three sociologists followed 790 Baltimore children over 25 years and published a book of their findings in 2014. Here is a quick summary of their results:

“The implication is where you start in life is where you end up in life,” Alexander said. “It’s very sobering to see how this all unfolds.”

Among the most striking findings:

  • Almost none of the children from low-income families made it through college. Of the children from low-income families, only 4 percent had a college degree at age 28, compared to 45 percent of the children from higher-income backgrounds. “That’s a shocking tenfold difference across social lines,” Alexander said.
  • Among those who did not attend college, white men from low-income backgrounds found the best-paying jobs. Although they had the lowest rate of college attendance and completion, white men from low-income backgrounds found high-paying jobs in what remained of Baltimore’s industrial economy. At age 28, 45 percent of them were working in construction trades and industrial crafts, compared with 15 percent of black men from similar backgrounds and virtually no women. In those trades, whites earned, on average, more than twice what blacks made. Those well-paying blue collar jobs are not as abundant as during the years after World War II, but they still exist, and a large issue today is who gets them: Among high school dropouts, at age 22, 89 percent of white dropouts were working compared with 40 percent of black dropouts.
  • White women from low-income backgrounds benefit financially from marriage and stable live-in partnerships. Though both white and black women who grew up in lower-income households earned less than white men, when you consider household income, white women reached parity with white men — because they were married to them. Black women not only had low earnings, they were less likely than whites to be in stable family unions and so were less likely to benefit from a spouse’s earnings. White and black women from low-income households also had similar teen birth rates, but white women more often had a spouse or partner, a relationship that helped mitigate the challenges. “It is access to good paying work that perpetuates the privilege of working class white men over working class black men,” Alexander said. “By partnering with these men, white working class women share in that privilege.”
  • Better-off white men were most likely to abuse drugs. Better-off white men had the highest self-reported rates of drug use, binge drinking, and chronic smoking, followed in each instance by white men of disadvantaged families; in addition, all these men reported high levels of arrest. At age 28, 41 percent of white men — and 49 percent of black men — from low-income backgrounds had a criminal conviction, but the white employment rate was much higher. The reason, Alexander says, is that blacks don’t have the social networks whites do to help them find jobs despite these roadblocks.

My quick interpretation: race and class still matter. White children could access jobs through social networks (a point also made in Deidre Royster’s Race and the Invisible Hand study of vocational students in Baltimore) and could still get jobs even with deviant behavior. White women partner with these white men and do better as a result. Starting in families with higher incomes leads to a higher likelihood of going to college. That these two social factors continue to matter should not be surprising – look at the life outcomes and changes by race/ethnicity and income for all American adults – but their presence can get drowned out.

Traditional neighborhoods vs. urban prairies: block by block in Detroit

Posted on by

National Geographic has quite a map showing Detroit with each block coded to be more or less less a traditional neighborhood or an urban prairie/naturescape. Here is the map:

DetroitBlockbyBlockNeighborhoodorPrairie2015NatlGeo

The map clearly shows clusters of both kinds of places, which contradicts the idea (reinforced by numerous stories and images) of recent years of a monolithic empty Detroit. As the text at the bottom left notes, “Many neighborhoods along Detroit’s perimeter are as densely populated as the city’s wealthier suburbs.” So it isn’t that all of Detroit needs fixing; neighborhoods that suffered from similar issues including deindustrialization, the loss of white residents, the lack of capital both for businesses and residents/homeowners, and crime do need the attention.

Ferguson doesn’t get much revenue from the Fortune 500 companies in town

Posted on by

Many suburban communities give tax breaks to corporations so that they locate in their community. Ferguson, Missouri is one such case where Emerson Electronics and other businesses don’t pay as much as they might in local taxes:

In 2014, the assessed valuation of real and personal property on Emerson’s entire 152-acre, seven-building campus was roughly $15 million. That value has gone up and down over the last five years as Emerson has sold off some buildings and built others, but it has not exceeded $15 million in the period since the data center was completed. So what happened to that brand-new $50 million dollar building?…

For tax purposes, Emerson’s Ferguson campus is appraised according to its “fair market value.” That means a $50 million dollar solar-powered data center is only worth what another firm would be willing to pay for it. “Our location in Ferguson affects the fair market value of the entire campus,” Polzin explained. By this reasoning, the condition of West Florissant Avenue explains the low valuation of the company’s headquarters.In fact, the opposite is true: The rock-bottom assessment value of the Ferguson campus helps ensure that West Florissant Avenue remains in its current condition, year after year. It severely limits the tax money Emerson contributes to the Ferguson-Florissant district’s struggling schools (Michael Brown graduated from nearby Normandy High School, a nearly 100 percent African American school that has been operating without state accreditation for the last two years), and to the government of St. Louis County more generally. On the 25 parcels Emerson owns all around St. Louis County, it pays the county $1.3m in property taxes. Ferguson itself receives far less. Even after a 2013 property tax increase (from $0.65 to the state-maximum $1 per $100 of assessed value), Ferguson received an estimated $68,000 in property taxes from the corporate headquarters that occupies 152 acres of its tax base—not even enough to pay the municipal judge and his clerk to hand out the fines and sign the arrest warrants.

St. Louis County doesn’t just assess Emerson a low market value. It then divides that number in three—so its final property value, for tax purposes, ends up being one third of its already low appraised value. In some states, Ferguson would be able to offset this write-down by raising its own percentage tax rate. Voters would even be able to decide which services needed the most help and raise property taxes for specific reasons. But Missouri sets a limit for such levies: $1 per $100 of property. As Joseph Pulitzer wrote of St. Louis during the first Gilded Age, “millions and millions of property in this city escape all taxation.”…

Emerson Electric isn’t the only business on Ferguson’s West Florissant Avenue. The street is also home to a number of big box stores including a Home Depot, a Walmart, and a Sam’s Club, located at the city’s northern limit. These companies all came to town in 1997 through something called tax increment financing—known (to the extent it’s known at all) by the acronym TIF. Along with low appraisals and tax abatements, TIF districts are one of Missouri’s principal tools for encouraging new development.

The conclusion here is that these tax policies reproduce the economic inequalities in Ferguson. Hence, the community has to find alternative sources of revenue, such as targeting motorists.

Here is where this gets trickier: if Ferguson didn’t offer these deals, could it have attracted these businesses? If many suburbs participate in the game of tax breaks, wouldn’t someone else offer good tax breaks? Where race matters here is that communities like Ferguson – lower income, transitioning from white to black over recent decades – have to offer even better tax breaks to compete. But, for all of these communities, it is a race to the bottom as a better deal to attract a corporation means less revenue for the city. Still, local politicians can sell the jobs created or the prestige generated. But, as this article points out, the jobs and prestige may not help much in the long run.

What you might need here is a metropolitan wide policy against such tax breaks or TIF districts to reduce the competition. Or, perhaps some tax revenue sharing program where sales tax and property tax dollars are partly redistributed to reflect who shops at or works at these facilities (they all don’t come from the community in which the firm is located). Yet, such policies require a lot of political will and again encounter the problem of race as communities, especially wealthier ones, will not want to share their revenues with others.

When broken sidewalks limit mobility

Posted on by

This story from Shreveport, Louisiana discusses how poorer neighborhoods in the city tend to have more problems with sidewalks:

But Murphy’s citation for walking in the street along Highland’s crumbling sidewalks spotlights the city’s infrastructure failures in the era of the new mayor’s promises to repair and beautify Shreveport’s streets…

For now, there’s no set date when Shreveporters can expect to see most sidewalks installed or fixed, though plans are in progress. And 25 years after the Americans with Disabilities Act went into effect, unsafe sidewalks with missing or poorly-maintained ramps are a common sight…

“If they contact our offices and let us know, we will do what we can to correct those places and make it accommodating for them because a lot of the places around town don’t have those ramps available and we are aware of the issues,” Harris said.

But in terms of fixing the city’s roads and sidewalks, Harris said residential neighborhoods take a back seat to downtown and other highly-trafficked areas…

The Shreveport-Caddo 2030 Master Plan includes a transportation component to address pedestrian issues, but it likely will be years before Shreveport is brought in line with major cities, according to Loren Demerath, a Centenary sociology professor who studies the importance of pedestrian spaces to communities and has been active in local efforts to make Shreveport more bikeable and walkable.

An interesting mix of race, social class, and disabilities all having to do with a simple piece of infrastructure: sidewalks. Without well-maintained sidewalks, it is difficult to be a pedestrian as it either requires a more dangerous route on the road or walking through grass or other areas. If anything, this would be a safety issue in many neighborhoods and discussing safety, particularly when it comes to kids or others who need more protection or space (the disabled or perhaps the elderly), tends to lead to better outcomes. But, it sounds like Shreveport has some work to do in this area and I would guess the city would cite funding issues as a reason the sidewalks are so uneven.

And for those who subscribe to broken windows theory, do broken sidewalks have a similar effect? While the residents may not have much to do with breaking sidewalks, it might just suggest that the city doesn’t care as much about the neighborhood.

Trying to move Los Angeles toward a less auto-dependent, greener, more sustainable city

Posted on by

To say the least, Los Angeles has a reputation as a car-friendly (and/or dominated) city. Some people are hoping to change that:

The most explicit attempt to capture the shift in the zeitgeist is the notion of the “Third Los Angeles,” a term coined by Los Angeles Times architecture critic Christopher Hawthorne. In an ongoing series of public events, Hawthorne has proposed that L.A. is moving into a new phase of its civic life. In his formulation, the first Los Angeles, a semi-forgotten prewar city, boasted a streetcar, active street life, and cutting-edge architecture. The second Los Angeles is the familiar auto-dystopia that resulted from the nearly bacterial postwar growth of subdivisions and the construction of the freeway system. Now, Hawthorne argues, this third and latest phase harks in some ways back to the first, in its embrace of public transit and public space (notably the billion-dollar revitalization of the concrete-covered Los Angeles River). Hawthorne’s focus is not specifically environmental. But a more publicly oriented city also tends to be a greener one. This is partly because mass transit and walking mean lower carbon emissions. And more broadly, willingness to invest in the public realm tends to coincide with political decisions that prioritize the public good, including ecological sustainability…

On all of those fronts, there are signs of change. One of the most obvious counter-examples is CicLAvia, the kind of phenomenon that makes Jacobs acolytes swoon. Launched in 2010, it’s a festive event during which miles of streets are closed to cars and swarmed by bikes. Taking place every two to three months, and rotating among different neighborhoods (Echo Park, the Valley, South L.A., etc.), each occasion attracts a diverse crowd of tens of thousands of people. They are the type of feel-good events—some might even call them utopian moments—where strangers smile at each other and ordinary life feels suspended. Traffic lights blink, and even cops whiz by on two wheels, wearing endearingly dorky helmets. In every sense—the car-shunning, the enthusiastic proximity to strangers, the exploration of different parts of the city—CicLAvia is antithetical to the guarded, privatized, auto-carved Los Angeles of lore.

CicLAvia remains a special occasion, but everyday transit is slowly improving as well. Banham wrote that the freeway “is where the Angeleno is most himself, most integrally identified with his great city,” and he predicted that “no Angeleno will be in a hurry to sacrifice it for the higher efficiency but drastically lowered convenience and freedom of choice of any high-density public rapid-transit system.” In 2008—pushed in part by unbearable traffic—Angelenos proved him wrong. On that Election Day, citizens of Los Angeles County voted for Measure R, which imposed a half-cent sales tax to support funding for transportation projects, including the expansion or construction of 12 rail and bus rapid transit lines. It is expected to generate $40 billion in revenue over 30 years. This choice stands in stark contrast to the famous Proposition 13, the 1978 California anti-property-tax law which has wreaked havoc on the state’s budget for public investment ever since. Jonathan Parfrey, executive director of the L.A.–based organization Climate Resolve and a former commissioner at the Department of Water and Power, told me, “The day we voted for Measure R, we voted for a new Los Angeles.”…

Starting in the early ’80s, the city got more serious about conservation, as seen in its mass conversion to low-flow toilets. The city has been responding to the current drought on a number of fronts. It has significantly reduced its own water use, especially in the Parks Department. It has offered a rebate to homeowners who replace their lawns with drought-tolerant landscaping, as well as rebates for installing rain barrels, among a variety of other measures. (It remains to be seen how the city will implement the new mandatory state restrictions.) The Department of Water and Power is also preparing a new Stormwater Capture Master Plan, and L.A. has a target of reducing imported water use by 50 percent by 2025. According to Andy Lipkis, executive director of the influential nonprofit Tree People, even in a drought, the proper technology can capture significant amounts of water—3.8 billion gallons per inch of rainfall. Mayor Garcetti just launched a corny public awareness campaign urging conservation. Contra Mulholland, the new slogan is “Save the drop.”

Early Los Angeles was a streetcar leader and the metropolitan region today is the densest in the United States (meaning that it is spread out but it is pretty dense in its spread). Yet, truly transforming the region away from reliance on cars requires a lot of work including: building mass transit (buses might be best given the roads but building light rail and subways could be more powerful in the long run even if they are incredibly expensive at this stage), approving denser development (not an easy task in a region where property values are incredibly important), developing a vibrant downtown that also includes housing units, and perhaps finding ways to deincentivize development on the metropolitan fringes.

Perhaps the best thing that could happen to Los Angeles in this area of green sustainability is the continued improvement in vehicles. Radically transforming Los Angeles may be a hard sell but slowly increasing MPG, introducing new power sources (fuel cells, hydrogen, etc), getting older cars off the road, and eventually having autonomous cars could be very helpful. Of course, those changes are not ones really made at the city or metropolitan region level but the guidelines of the state of California and the federal government may just go a long way.

Identifying the pockets of carless Chicagoans

Posted on by

With more Americans living alone and significant transportation costs for middle-class Americans, where do the carless Chicagoans tend to cluster?

So where do those carless Chicagoans live, and how many of them are there? A lot, it turns out. If you break down Chicago by cars and household size using 2012 census numbers, these are the only groups of more than 100,000:

One person, one vehicle 193,174
One person, no vehicle 168,004
Two people, one vehicle 135,143

Along the northern lakefront, around half the households don’t have a car; there are pockets in the Near North Side and Lake View over 60 percent. In one Edgewater tract, it’s over 70 percent. It’s not the highest percentage, though—there are two tracts in one of the poorest stretches of the South Side, between U.S. Cellular Field and 47th Street along the Dan Ryan, above 80 percent.

As you move north and west and the city gets less dense, the percentage of carless households drops off. There’s an exception, though: one tract in Logan Square, adjacent to the California Blue Line stop, where 41 percent of households don’t own a car. The “twin towers” transit-oriented development that’s going up at 2293 N. Milwaukee, and causing controversy as it goes, will live right next to that tract.

If I had to guess, this is related to income, age, more expensive parking options (for example, having to pay for a garage spot as opposed to plenty of street parking), and housing types (single-family homes which are more attractive to families versus apartments, condos, etc.). How well would these clusters line up with where the Creative Class lives?

The headline suggests that this is has led developers to respond with what they are proposing and building. Yet, the article doesn’t say much regarding these changes. For example, how about more shared streets like have been proposed for a few spots in Chicago? How about more bike lanes in these areas? How about more high-rise housing? If these population clusters hold and developers are indeed responding, these could be very unique places in a few decades.
