Unraveling Urban Life and Space

Work/Learn at Home - Outside Edition, Part 2

9/2/2020

​This week we’re back to working at home, specifically more about making yourself a great workspace outside. Why now, at the end of the summer? Because, as a lifelong outdoors person, I can tell you September and October are some of the best weather for outdoor living, especially after this brutally hot climate change summer. Plus you can push comfort in outdoor spaces farther into cold weather than you’d think, something we’re all keenly interested in this year, and something I’ll be posting about soon. 


Without further ado, here’s your landscape-architect-approved…
 
Five More Ways to Make a Great Outdoor Workspace: 
(or Study Space, for those still-at-home kids)

Fan/heater 
For real luxury, add an electric fan to that outdoor workspace. This can be as simple as plugging a portable fan into an extension cord, or as elaborate as installing a ceiling fan into the porch ceiling. Fans help with flying insects, too, if that’s an issue. You know about patio heaters and other heat sources outside, but let me point out two things: 

1) if you want a patio heater, buy it immediately, because as soon as this extra-hot summer wanes, there is going to be a big demand for those this year.

2) working by a firepit sounds delightful, but from personal experience, it doesn’t happen. Nothing is as distracting as fire. You’ll have a marvelous relaxing few hours sitting by the fire…and doing no work at all. 

Storage space
Outside you can’t leave papers and electronics spread out for days, which is both a plus and minus. You’re forced to be more organized. There are outdoor cupboards and such on the market, but I’d approach this like working in a library or coffeehouse or other public setting: you bring it with you and you take it with you. 

What you need therefore is a good bookbag or a portable file box or something of that sort. You’re at home, so this storage could be more fun: beachy tote bags? A clean wheelbarrow? Those bike panniers you never use (and the world’s shortest bike commute)? 

Space for a guest
Whether that’s a sibling, a spouse, or someone genuinely from the outside world, you need a place to sit - a movable chair - and maybe a spot for a cup of coffee. If you’re having in-person conversations with anyone you don’t live with, outside is the safest place to do it. For kids studying outside, that guest is likely to be you, helping with lessons and technology. Make yourself comfortable while you try to remember math about fractions.

Fun stuff
There’s a whole universe of patio, pool, and backyard accessories out there to liven up your outdoor space with. Maybe keep the inflatable pool toys out of sight of your Zoom camera, but there’s still plenty of space for some strings of lights, flags, or flowers, which brings me to:

Use the nature you’ve got 
​Looking at or being near plants and non-threatening animals makes humans like us more relaxed, less depressed and anxious, and less mentally fatigued. Has there ever been a time when we needed this more? What you need is some greenery in your view most of the time. Trees are better than just lawn, but even a flower pot is worthwhile. Extra credit for backyard birds, maybe attracted to a birdbath or feeder.

Health boosts from Nature: quick reference for Practitioners

7/1/2020

 
PictureYou don't need a gorgeous view like this to benefit from nature, but isn't this soothing? (Author photo)
​There’s never been a better time to keep nature-health benefits at your fingertips if you're in the business of shaping outdoor spaces or activities for people. Health is on people's minds like never before as we fight COVID-19. You know all about nature-health benefits because you took my class, right? Even if you didn't (or if you can't remember everything), here’s a two-minute pocket reference, yours to bookmark and share. 

Specific to the pandemic, peaceful natural areas, especially vegetation and water, can help with several of those pesky underlying conditions that make us high-risk for infection, serious illness, and death. Research has shown that being around such areas measurably lowers stress indicators in the body, like cortisol levels and blood pressure. Other studies have found associations between nature exposure and lower rates of cardiovascular disease, diabetes, and inflammation.  Some studies have even found improvement in immune system function. Like the immune system function we need to fight off this virus, for example.  

Speaking of extreme relevance: time in natural environments can also reduce anxiety and depression, as well as mental fatigue and even full-blown PTSD.  Who couldn’t use that right now? Here’s a handy list of those benefits, from my book-in-progress: 

Mental Health benefits of urban wilds
(from "Wild and Healthy" in Design by Deficit: Neglect and the Accidental City)
  • Reduces mental fatigue 
  • Improves alertness, performance, memory
  • Reduces stress/impact of stressful events 
  • Reduces depression
  • Enhances cognitive functioning
  • Reduces childhood ADHD symptoms
  • Reduces negative symptoms in dementia patients
  • Increases life, place, job satisfaction

A couple things to remember about this research: 
  1.  These are rigorous published studies, not merely opinion or conjecture. 
  2. These benefits work best via every day exposure. In terms of wellness habits, nature exposure is more like brushing your teeth than like running an ultra-marathon. It works, but you need to do it regularly to get the benefit. It’s not about overnight miracles.
  3. You don't need a wilderness or a jaw-dropping view to get these benefits. Street trees, planting beds, even just a view with vegetation works. Small is fine, if it's all the time.
  4. By and large these studies don’t make strong statements about *how* these links work, but that likely doesn’t matter much to you if you just want to get your blood pressure down. 

If you need more information about any of these benefits: 
Here’s a good readable article suitable for distributing to your clients.

Here’s an authoritative journal article for those who want more science in this. 
​
And here’s a comprehensive resource about benefits of nature for cities from the University of Washington, College of the Environment, with an extensive bibliography for further reading as well as a really readable guide to benefits.







Spooky Hollows: Fear and Protecting Nature

10/8/2018

 
Picture
Image from pixabay.com. although honestly this could be any house in Connecticut.
It’s October. Every door creaks, every picture has eyes that follow you, every call is coming from inside the house. Night falls sooner, mist swirls, dry leaves - or footsteps? - whisper along every path. Bats fly out of the tower on the old house at the edge of town, and surely phantom hitchhikers wait along every lonely road. 

Picture these spooky scenes. Where do you see them happening? Everybody knows a spooky place. A place that makes the hair on the back of your neck stand up. Not just dangerous, but eerie. Maybe not now, but years ago when you were a child, you knew a place like this - the haunted house, the old cemetery, maybe just the basement or attic. 

Remember it, then ask yourself: have you really outgrown spooky places? What scares you, and where is it? Maybe it’s Area 51. Or your favorite Bigfoot hotspot. Or Point Pleasant, West Virginia, or (the former) Edmonson, Kentucky. 

We’re justified in fearing some places, because they are contaminated, a scarier scare for the fully grown than whatever’s going bump in the night. Paranormal or aliens or radiation, eerie places are fascinating in a way that your run-of-the-mill dangerous place is not. Show me a dangerous intersection, and I’ll show you a place you avoid but never think about. But what’s eerie combines fear with mystery - and mystery is a potent, enduring universal attractant. 

Mystery, in fact, is one of the aspects of landscapes we find attractive, according to research on the subject. That general rule is this: that we are intrigued by scenes that we can’t immediately understand fully, because they invite exploration and hint that there’s more to be learned from them. Spooky places are mysterious, but they also scare. Two reasons to notice them, remember them, and care what happens to them, for good or ill. Another general rule: we place less value on what’s overgrown and unkempt, because those places look like no one else values them. But what good is a well-maintained spooky place? It’s just ordinary. A greater feeling of abandonment makes an eerie place eerier, and perhaps that much more mysterious/frightening. Our feelings about them are, in a word, contradictory. 

Also contradictory is that spookiness can protect a place. We aren’t indifferent toward places we fear, and indifference is the real enemy here. Indifference is what makes a place invisible, and that invisibility makes it ripe for a new Wal-Mart or subdivision or what have you. That protection can create a space for nature. To see this in action, you wanna see something really scary. Like Chernobyl.

In 1986 an accident at Ukraine’s Chernobyl Nuclear Power Plant caused one of its reactors to explode. At least 50 people were killed immediately, and 120,000 residents were evacuated. The site remains radioactive today. A vast 1,000 square mile exclusion zone surrounds the site, including the abandoned city of Pripyat.  

Today, Chernobyl is famous not just for the disaster, but also as a haven for wild horses, elk, boars, bison, and most especially wolves. There’s room for them to live and thrive (radiation notwithstanding) because we humans are too afraid to enter that place enough to disturb them. Chernobyl is the perfect example, because we’re afraid not just of the place, but of objects and resources, like timber, that might be extracted from that place, and it’s a big place - 1,000 square miles! Big enough for wolves to thrive. 

Nuclear contamination is authentically terrifying, but there’s also a thousand horror stories about mutants, people or animals or viruses, and about you yourself becoming mutated. We can’t see radiation or contamination, so we can’t tell if it’s gone or increasing or creeping up behind you. That’s sinister. At this point, thirty-odd years on, the sheer size of the abandoned area around Chernobyl is unnerving because who knows what’s really in there? If you go in and get into trouble, no one can hear you scream. It’s self-perpetuating spooky.

Bring contamination closer to home, subtract the radioactive wolves, and you come to Love Canal. Love Canal is a former subdivision near Buffalo, NY, made infamous as a toxic waste disaster. The homes and, incredibly, an elementary school, were built on the site of an abandoned canal project (hence the name) that was used as a chemical waste dump in the 1940s and 1950s. A disease cluster in the neighborhood prompted grass-roots investigation, revealing that chemicals were leaching through groundwater into area basements and yards, as well as the school playground (!). A lengthy and intense struggle by neighborhood activists (mostly women) led to the relocation of over 900 families, and eventually to the creation of Superfund by the federal government in 1980. The disaster exponentially increased public awareness of the dangers of industrial pollution, particularly in working-class areas (like Love Canal) and minority neighborhoods.

Today the site of these vanished homes is a parcel of approximately one square mile, comprised of meadow, more or less, and scattered trees. It’s a savanna with crumbling driveways and roads, surrounded by chain link fence. A landscape that’s terrifying, if you’re old enough to remember Love Canal as breaking news; unsettling, if you are one of the residents across the road wondering about the genesis of their ailments; welcoming, if you are a rabbit or possum or deer. 

Industrial contamination is scary stuff, and the nature of pollution underground, in ground water, or in the soil, or in your basement courtesy of your sump pump, is, again, hidden and mysterious in its extent and severity. They say it’s gone. Is it? The idea that we’ve unleashed dangers we can’t control, be they industrial or nuclear, is a very disturbing one - and a fascinating one, as illustrated by most Twilight Zone episodes, a lot of science fiction, and any scary story about repeating names while looking in a mirror.   

Spooky/ nature spaces don’t have to be famous. I used to live near Split Rock, an overgrown abandoned quarry and industrial ruin in Syracuse, New York. Already you see the eerieness, right? - “abandoned quarry,” “industrial,” “ruin” - but there’s more: in 1918 a factory making explosives for World War I exploded, creating a horrific fire that killed fifty men and critically injured fifty more.

Today the Split Rock  quarry is a big blank spot on the map, approximately 900 acres of woods and brush - and according to some, paranormal activity. It’s a place where roads dead end, with a few rusty “Danger - no trespassing” signs for atmosphere. There’s plenty of good reasons to leave the place alone: old quarry cliffs and holes, industrial ruins, worrying contamination from that munitions plant, and the very real danger of getting lost in the deep, dark, possibly haunted woods.  While not truly urban, Split Rock is close enough to the city to keep me alert for urban ills. There may be a few of those there, plus the occasional ghost hunter, and surely mountain bikers using the unofficial trails. But mostly, Split Rock is left to the deer and the coyotes and smaller creatures. 

Set aside the specters and the chemicals, look at these places as natural landscapes, and you’ll find they look pretty good. Sinister places benefit us just like any natural area, benefits like cleaner water, reduced flooding, less urban heat island, and carbon sequestration, the whole ecosystem services  bundle. These processes are going on in each of these places; some of them are doing all three. They benefit us even while we fear them, and their enduring mystery helps keep us from destroying them, thus protecting their ability to continue helping us. 

Fear can create space for nature to recolonize, recover, even thrive. Contaminated sites are especially good at discouraging development, partly because they tend to have sticky legal issues about what’s there and whose fault it is and who should do what to clean it up. 

Yet plenty of eerie places have no natural value. Most buildings reputed to be haunted are just buildings - ecologically speaking, the most haunted house is just a house, unless it’s got an overgrown yard. Lots of horrifyingly contaminated brownfields are redeveloped  into utterly mundane things, like freeways or strip malls, and people forget what they were. Even the sites of authentically horrific events like Civil War battles, can struggle against encroaching development. Sites like Chancellorsville, where 24,000 men died in 1863, arguably could benefit from being more spooky, thus helping preserve them. 

What makes the difference, turning an unsettling place into a natural space as well? Is there a way to harness spookiness to help preserve natural areas? Can we use this without it backfiring and creating a place so eerily fascinating that people love it to death? 

Back in the ‘90s, there was an interdisciplinary effort to design a warning landscape to scare away humans (or any other intelligent life) in perpetuity from nuclear waste storage sites like Yucca Mountain and the Waste Isolation Pilot Plant. Yucca Mountain, in Nevada, has since gone kaput as a doomsday nuclear storage facility, but the Waste Isolation Pilot Plant in neighboring New Mexico is socking away nuclear waste underground, and still asking how to keep people away long after our civilization and language have crumbled into dust. 

Fear, made to act as a warning. Spookiness to save your life. Think about it, maybe while you ignore the tapping at the window and tell yourself the shadows on the stairs aren’t moving.

Shrubbiness: When a tree isn't a tree

7/25/2018

This post is a preview of a sidebar in my upcoming book about the neglected city, Design by Deficit. Also posted on Medium. 

​Syracuse, New York, the city where I used to live, is a shrubby place. By that I mean that unmaintained land within the city quickly becomes colonized by woody vegetation above waist height, but below the height of shade or canopy trees. This is the ecological process of succession, but it’s succession with a twist: it’s being done by what Peter del Tredici calls, “cosmopolitan urban vegetation.” This mix of natives and exotic invasives includes several of the Most Wanted on the list of invasives in the US: shrubby honeysuckles, autumn olive, Japanese knotweed, and of course, public enemy #1, buckthorn. This paper called out Syracuse as one of the only cities in the US where overall tree canopy is increasing, probably because of the buckthorn. That’s a lot of buckthorn. At least it’s too cold here for kudzu ...so far.

Syracuse isn’t alone. Cities in the eastern US, particularly those that have lost industry and population, have shrubby places in part because of this collection of large invasive shrubs, and the rainfall to support them. Numerous other trends converge in shrubbiness: vacant land, abandoned properties, tight municipal budgets that restrict mowing, but also an increased value placed on wildlife habitat and natural-looking landscapes. 

Urban shrubbiness sits at the junction between two established findings about human behavior and vegetation. In this research, tree canopy is the panacea, or nearly so. Tree canopy does it all - we think better, behave better, feel better, and like places and communities better when there are shade trees, to paint this research very broadly. Yes, these are largely studies finding association, not causation, and experiments are hard to design on this topic, but the association is consistent across many studies by many people, and in the end, there’s not much downside to planting trees, as we argue here. But on the other hand, there’s cues to care and loose space, research and theory that argues that we generally perceive apparently unmaintained land (such as that covered with successional vegetation) as out of control and outside the rules, fit for transgressive activities like vandalism. Tall dense vegetation - shrubbiness, again - has been shown in numerous studies to be a less preferred environment that makes us feel insecure, perhaps because we doubt our ability to navigate through it or discern threats within it. 

So shrubbiness is both good and bad, from a human behavior standpoint. Which wins out- the positive or negative impacts, or is it a draw? For that matter, invasives, or the cosmopolitan cocktail of urban vegetation, are a mixed bag ecologically as well. Invasives (like buckthorn) are demonized because they damage biodiversity and don’t do all the good things that their less-competitive native counterparts do, but sometimes, well, a tree’s a tree. They all photosynthesize, and mitigate heat island, and help slow stormwater runoff - or do they? There’s an implied balance sheet here, weighing the good and bad impacts of unmaintained urban understory vegetation in terms of social, economic, and ecological good. 

A tree isn’t a tree when it’s buckthorn vs. white oak, but many of our best and most sophisticated ways to measure urban vegetation in quantity (meaning on more sites that you can visit in person) sees those as the same.

In the lack of distinction lies the mystery; this devil’s in that detail.

What’s the impact of the shrubby city, and how do we find out? What about drier cities or ones without a Syracuse-caliber winter? Is the impact different there? If the environment matters, shouldn’t these differences matter, too? As climate change makes some places wetter as it dessicates others, and we all get hotter and hotter, we may find we want to know whether shrubbiness is working for or against us. Invasive large shrubs aren’t going away. We might as well understand what they’re doing to us.

Low-Lyme Landscape

This adorable little fox kit wants to grow up and eat Lyme-infected mice! (Photo by author)
This post is a preview of a sidebar in my upcoming book about the neglected city, Design by Deficit. Also posted on Medium. 

If you spend a lot of time outdoors, like I do, you’re more or less perpetually alarmed about Lyme disease. Even more alarming are the array of other tick-borne diseases  that are way scarier, but reported at much lower levels - SO FAR!! As always, it’s easy to panic, and difficult to know what to do. 

Those rare-but-scary other diseases make solutions that only work on Lyme, like vaccinations, only so promising. More promising are solutions targeting these diseases’ common factor: what people are doing, what ticks are doing, and where they meet each other. 

There’s some surprising tidbits to be found in this. Like this: most people are infected with Lyme in their own yards, during daily activities, not out in the woods on that hike or camping trip. Maybe this is because we think about ticks in the woods but we don’t at home. Or perhaps people who choose to be out in the woods are people more likely to know about ticks and take those precautions - you were wearing special hiking clothes anyway - while people doing daily activities in their yards are just people, without that self-selection effect. 

You can’t stay in the house forever, so can you de-tick your yard or de-Lyme your ticks? Another surprising fact: deer aren’t the main villains here. The tick in question is the deer tick (aka blacklegged tick), so white-tailed deer get blamed for this modern plague. But a closer look at the life cycle of Lyme-infected ticks reveals the key middleman is much smaller and more common: the white-footed mouse. As mice tend to be, they are around in large numbers, unnoticed, and closer than you think. You see deer, but not mice. This particular mouse likes woodsy areas and their edges. Your yard will do fine, especially if you live in a heavily wooded area like much of New England, ground zero for Lyme. 

It’s tough to exclude mice from your yard. You can fence out deer, but just try fencing out mice. What really works to suppress mice is eating them. Since you probably don’t want to try that yourself, it’s lucky that foxes are very happy to do that job. A 2017 study found that indeed, where there are more foxes (and some other European predators, where the study was set), there are lower numbers of Lyme-infected ticks and ticks in general. Surprising again, the key dynamic in play seemed to be that mice move around less when there are predators around, as the study’s authors speculated. There are still mice around, but they are kept under wraps by the foxes, so they encounter fewer ticks. 

Red foxes are champion mouse eaters, and where foxes are, there tend to be other creatures. Some of these, like opossums and possibly turkeys, eat a lot of ticks, which helps in a different way. Others could help in a less direct but effective way by serving as alternate hosts for ticks. This means the ticks bite other creatures, like squirrels, that are less likely to carry Lyme disease instead of disease-carrying white-footed mice, and therefore never become infected with Lyme. You may still get bitten, but you won’t get infected if the tick that bites you doesn’t carry Lyme. 

How do you get foxes on board in your backyard fight against tick-borne disease? You do it with landscape management, looking at your yard and neighborhood as habitat. This starts with trees. A landscape with very small patches of forest is good for mice, but not larger animals that prey on them or on ticks. A landscape with larger patches of forest has the potential to house foxes and possums and so on, thus keeping the lid on mice and ticks and Lyme.  In urban areas, tree canopy is often referred to as the critical factor in the presence of foxes and other larger wildlife. It stands to reason, though, that what’s under those trees matters, too, as well as what kind of trees they are. More diverse woodlands with greater diversity of plants at ground level, especially native plants, tend to be home to greater diversity of wildlife. 

What else makes up the low-Lyme landscape? At a more detailed level, it’s less obvious what’s good and bad. Leaf litter is the natural cover of the forest floor, but it’s also habitat for deer tick nymphs and larvae. Brush and tall grass create good wildlife cover, but they are also the preferred spots for adult ticks to lie in wait for someone to bite. Every creature needs a water source, but dampness and humidity are key to deer tick survival. Obviously there are a series of trade-offs here that merit more study to discover the right balance. Foxes in particular need den sites, hollow logs or buildings to dig under or similar. But these same denning sites can also make the fox’s larger cousin, the coyote, at home, which brings us to one last surprising fact.  

Where there are coyotes, there are fewer foxes, because the bigger, stronger coyotes tend to kill the foxes. So if more foxes means less Lyme, do more coyotes mean fewer foxes and therefore more Lyme? That’s exactly the suspicion of a few researchers studying the matter, who note that the key factor in the outbreak of Lyme in New England may have been the arrival and establishment of coyotes in the region. 

So stay tuned, but consider what a low-Lyme landscape might be. Maybe also consider what the fox is worth to you that keeps you from getting Lyme disease, and what the forest that nurtures that fox is worth, too. The assortment of creatures living around us and the web of their interactions with each other plays a surprisingly key role here. You can surround yourself entirely with pavement and buildings. You can do the vegetated version of that with closely mown, chemical-soaked lawn. Or you can have a diverse, intact woodland edge ecosystem that works just well enough to allow predators like foxes to keep the mice and their ticks in balance, without making coyotes too much at home. Wild, but not too wild; just wild enough.

New Study: Greenspace and Stress

8/29/2017

 
I'm pleased to announce I have a new study out this week, co-authored with former student Meghan Hazer and two Upstate Medical University faculty, Margaret Formica and Chris Morley. "The relationship between self-reported exposure to greenspace and human stress in Baltimore, MD," presents an investigation of the reduction of stress associated with spending time in or looking at green spaces. The article is available now online and will be out in print in an upcoming issue of Landscape and Urban Planning. As a journal article, it will be behind a paywall soon - but until October 13, it is available open access (that's free full text!) at this link: https://authors.elsevier.com/a/1Vbv0cUG56y~D

Single-Track Saves the City

8/22/2017

 
Also posted on Medium.

​Call it biking the urban wild. Portland, Oregon, is developing a citywide off-road trail network, called the Portland Off-road Cycling Master Plan. Conventional planning processes will produce a network of single-track trails through natural areas, instead of the much more common paved bike/pedestrian trails. Portland is reported to be inspired in this effort by the broad popularity of mountain biking within the area, but the advantages of “wild” urban trails over conventional multi-use paths are worth considering anywhere. A network of single-track through the city is a network of urban wilds, with a built-in community of people to use them. 

What are these advantages? First, there’s the array of benefits to physical and mental health that come with exposure to everyday nature, particularly vegetation. Key to this list are lower perceived stress, greater time spent exercising, and improved mental focus. These three benefits lead to a host of secondary effects, from lower blood pressure to better mood and social relationships. Research on this nature-health connection generally finds that benefits are significant, but small, meaning that the ideal way to benefit from them is through activities done on an everyday basis. Thus, the trail through the natural area across the street is potentially much better for your health than the trail at the state park twenty miles away. It’s the everyday that makes the difference. 

Key to the the mental health benefits is mindfulness, or the necessity of being present and focused on the moment. The more rugged surface of unpaved trails promotes this, as does the narrowness of single-track. The limited views through trees and shrubs promote the feeling of being away from the city, even in locations well within city limits. This feeling of being away, or “extent,” is also key to achieving health benefits from nature, as is the feeling that a landscape can’t be understood completely at a glance, that it contains scope for exploration. 

Biking or running on a trail is obviously good for the trail user’s health, but it’s also good for everyone else’s health, in terms of the climate change mitigation benefits of urban wilds. The abundant vegetation of natural areas in cities sequesters carbon, which aids in offsetting climate change. These same natural areas also help cities adapt to the impacts of a warmer, more volatile climate, through lowering the temperature of adjacent areas and creating more area for rainwater from storms to infiltrate.  

Urban trail networks of any kind fight climate change by promoting human-powered transportation over cars, but an urban off-road network in an outdoorsy town like Portland goes further. If many people - Portland found 12% of county residents - are already doing single-track recreation, they are likely driving to those trails. Trails in the city eliminate at least some of those trips. This is not to say that trail users will never drive out of town, but as with everything having to do with lowering our impact on climate change, it is what you do routinely that matters, not the special occasion. It's the Tuesday night ride, not what you do one Saturday each summer.

An urban wild network promises major advantages to local wildlife and its ability to withstand the disruption of climate change. A substantial challenge for wildlife of warming temperatures and changing precipitation levels is the ability to move fast enough to keep pace with a livable climate. For some creatures, this means moving up in elevation or farther north to stay with cooler temperatures, while for others it means moving to stay with adequate moisture levels. Cities and many suburbs are obstacles to this movement, because they interrupt the habitat necessary to allow wildlife to travel. This fragmentation of habitat is offset by urban wilds, especially those that occur in a connected network, because the wild areas provide wildlife corridors, a kind of safe route for creatures to move through the city. Even manicured lawn, like in the top photo, is inhospitable to many organisms. Even though it’s green, it lacks sufficient shelter and may well lack adequate food and water sources as well. 

There are more benefits - reduced maintenance, improved views from adjacent properties - but this short list illustrates the advantages of a wild trail network like this in an urban area, that are not available with a more conventional trail network. Intriguingly, a wild trail network may be much less expensive, and therefore far more feasible, to build in urban areas that already have ample amounts of vacant lots, brownfields, and other urban wild spaces. Traditional trails are surprisingly expensive to build, so the cost difference between simply adding single-track to existing wild areas and clearing those areas,  establishing lawn, and constructing an asphalt trail, could be quite substantial. Since urban wild spaces are usually seen as waste space, using these spaces more or less as they are to get a desirable recreation and health benefit is well worth considering, for many places other than Portland. Maybe your town needs some killer in-town single-track, too.

Data: Sci-Fi Staple and Next Big Thing

1/19/2016

 
Picture
www.crn.com
Data* is one of the big ideas of our time, or better said, it’s a big idea following on the heels of a mammoth established trend. This makes it much more powerful than if it were merely an idea, because it’s an idea resting on a foundation of facts. Those facts are that our lives and opinions and environments are documented to a completely unprecedented extent, and that documentation - that data - is available to third parties. Frequently it’s publicly available, or available to anyone with the skills and savvy to figure out how to get it, or it’s the property of some Big Authority somewhere. Regardless, it’s not really under your control, particularly because there’s so much data that tracking what you produce is a full time job. Social media, photo sharing, fitness trackers, web use, remote sensing, financial transactions…the list goes on and on. 

Besides being the plot of nearly every dystopian movie ever, the rise of Big Data is a mega-trend. That makes it a good candidate for the biggest influencer of the next 25 years, which concerns us in this course and anyone planning to work anytime before 2041. I imagine (hope) that includes most of us.

So what does data mean for urban environments and their residents? What does it mean for urban design?
That’s a question without a ready answer, which is a good reason to study it: any question worth asking doesn’t have a ready answer. So, how to go about answering an answer-less question? 

Look at what’s already been done around the edges of the question. In this case, that includes data-based plans for very large cities, performance landscapes, and citizen science. Green building, to a large extent, relies on data, particularly in the myriad rating systems required to achieve various certifications or credentials. These are based on checklists, and checklists, like surveys or quizzes on Facebook, are data. These certifications also strive to be objective and quantitative in their measurements, so they rely on thresholds and ranges - data again.   

At the outskirts of data + design, things get really weird, meaning futuristic and mind-blowing, with just a hint of sinister. Environments that respond to individuals via real-time data. Buildings joining the “internet of things.” This is all pretty hard to imagine, but there’s this thermostat already on the market. Research on office systems that adapt to individual users is going on right here right now, at the Syracuse Center of Excellence indoor environmental quality lab.  

Most of these projects differ in scale from our interests, with the metropolitan region plans at one end and that thermostat at the other end. What does data mean for the neighborhood or site scale?

If you’ll indulge me in a Gen X moment, I’ll observe that back in the day when I was doing my first degree in landscape architecture (ca. 1995), we made a lot of assumptions and generalizations about site functions and use because we had no data. You could talk to the client, visit the site in person, and collect your aerial photos - taken from a real plane about every five years and available only in hardcopy -  from the county offices. If the project went forward and the client hired you, you’d have a survey done - with actual instruments on the actual land - and then you’d know the topography and the dimensions of structures. You could sometimes get as-built drawings of buildings. It was nothing like the data glut we live in today. So design decisions often got made according to what we “knew,” not what we really knew, following, for example, the boss’s pronouncement that “no one plays tennis anymore.” Therefore: the park plan without a tennis court. 

My point, digital natives, is that the atmosphere or paradigm then was data scarcity, so we created ways of doing things that compensated for or disguised that lack. Tradition, culture, and convention have great influence in design; perhaps they do in every profession. Realize that much of “the way we do it” may/is/could be based on this data scarcity. A big part of earning a professional degree in any design field is learning “the way we do it,” so be wary.

How will urban design practice embrace the era of data?

Let’s find out.




WHAT DO I DO FOR CLASS? 
  • Read this post and click on all the links within it. 
  • Read the articles; review (that means look through, but don’t read every word) the websites.
  • Think about what you agree with, what you disagree with, and what doesn’t make sense to you. 
  • Come to class prepared to talk to your classmates about it.

*Yeah, I know it’s plural. In keeping with the informal tone and breezy feel of this blog and my classroom approach, I’m sticking with the common usage of “data” as singular.

The Vanishing Infrastructural Wild

What's the cost to wildness of updating infrastructure?

“Urban wild” immediately brings to mind corridors, the linear routes of infrastructure like interstates an
d power lines.  Paul Gobster lists such corridors as one type in his typology of wildscapes, so I’m not alone in this observation. 

Let’s think about these corridors as spaces. These are perfect examples of forgotten spaces that we train ourselves not to see, yet they are large swathes of the city. Utility corridors and freight rail corridors tend to run along the backs of properties - or better said, the properties around them align along the corridors - so it’s easy to miss them in everyday life. These corridors are negative space framing the positive space of the lots around them. The more overgrown (wild) they are, the more they disappear. Interstate corridors are really a contradiction, because we drive through them constantly. Yet what forgotten invisible spaces they are. Here in Syracuse and back in Ann Arbor, and surely a host of other places, interstate corridors are popular spots for homeless camps, which is the best proof you could have that most residents don’t see these spaces. They also collect trash - lots of trash- and are frequent sites for graffiti, both suggesting that these are seen as spaces no one owns. Invisible, yet right in front of you.

Why are these spaces wild? Sometimes they aren’t. In Indiana my husband and I own a rental property in a subdivision that’s bisected by high voltage lines. The space under these lines is kept mowed, if not manicured, and includes some businesses, restaurants and offices. Within the subdivision, the space under the lines contains a retention pond that the houses look out on. Elsewhere in my home state, the interstate right-of-way used to be (maybe still is) kept mowed. You probably know other stretches of highway that were mowed like this. Although interstates are federal, of course, the mow/don’t mow decision varies by state: Indiana mows; Michigan doesn’t. The interstate right-of-way is suddenly wilder as you go north. 

It’s more popular now to not mow. We know why that is. It might be habitat or carbon reduction or some other ecological rationale, but primary or secondary rationale is always money. Mowing cost seems negligible, but…it’s all the time, over and over, year in, year out. Someone pays for it, and why is that, again? Why mow all of it, or any of it? Over the past few decades it’s become more popular to plant wildflower mixes (sometimes natives, sometimes not) in interstate margins like this and stop mowing. The same belt-tightening reflected in the maintenance (or not) of transportation ROWs is surely in play with utility ROWs as well; even less reason to mow land no one sees. Possibly there is advantage in having utility corridors and substations and other assorted bits and pieces of the equipment that keeps the lights on be unnoticed by the general public. You don’t vandalize what you don’t see, and neither do you pay too much attention to what’s going on there or fuss over trees topped to stay clear of lines or whatever. It’s the power company’s business what happens in their little wilderness, and maybe they’d prefer that no one else go there.

Except…people do go there - see above re: homeless camps and graffiti. See all previous discussion about transgressive spaces and cues to care and loose space. Wild spaces are loose spaces, the international waters of urban life, where anything can happen. And if a utility corridor is a wild space, well, it’s loose, too. 

So infrastructure corridors are wild spaces, socially and naturally, but why “vanishing?” At the risk of mixing a metaphor between “invisible” spaces and “vanishing” spaces, follow this logic: 

Energy and transportation are on the cusp of a sea change (to add another metaphor into the mix). Use of fossil fuels faces questions about supply and peak oil, political instability, and the increasingly serious need to address climate change. There are great gains to be made in efficiency, including the landscape-scale issue of where we live in relationship to where we work, and how we get around. Much of our transportation infrastructure in the US dates from the years following World War II, when the interstate highway system was constructed, giving rise to a million suburbs on the public dime. We know this story: the suburbs boom, the cities bust, and we all drive - a lot, alone, in Detroit steel, then massive SUVs. Denser development is more sustainable development. Denser development requires less transportation, is better suited to mass transportation, and at the very least, is more feasibly served by a diffuse grid of surface roads than by limited access highways.  This isn’t the end of interstates, but they’ll be less emphasized in the future, and probably share the space of their roomy corridors with other uses and transportation modes. And yes, perhaps some will be dismantled or converted to other uses or downsized. Exit one type of infrastructural wild.

What could make a much bigger difference is a switch to more distributed energy production. Distributed production means energy produced near its point of use, at many locations, in contrast to one large generator, like a power plant. Distributed production is inherently more resilient, because it’s many instead of one, and in many locations instead of one - the eggs are separately arrayed over a large space instead of being all in one coal-fired basket. Distributed production dovetails nicely with clean energy generation, and with smaller-scale energy systems (microgrids) that can remain functional with or without the larger grid in operation. So distributed energy production seems to be the way of the future for several reasons. 

If you think about it, and most of us don’t, the current electrical system requires a lot of moving power from place to place, to speak in a decidedly non-technical way. Electricity is generated at large power plants, then travels along a series of increasing smaller lines until it reaches the outlet in your wall. It’s a lot of ground to cover, to say nothing of transporting the fuel to the power plant to begin with. As electricity travels, some of it dissipates, so distributed production means less of that loss; a benefit maximized by placing generation next to use. It seems inevitable that this will mean vacating some of the existing system of lines and structures that currently move electricity from power plant to use. 

High voltage corridors are large. Look at an aerial photo, and they stand out, x-ing across miles. That they are corridors is in itself valuable, because corridors are difficult, impossible, really, to assemble through land that’s already owned by many different entities and developed into different uses and buildings. A vacated corridor is an intact corridor, and it could be intact for something else, even if it’s merely a right-of-way or easement and not owned outright by the electric company. Corridors preserve protected routes for wildlife movement, helping counteract habitat fragmentation. This aspect of utility corridors is even more important in urban areas, where the surroundings may be entirely built out and thus inhospitable to most wildlife.

It’s worth thinking about and assessing what they do for us in their current state, these infrastructural urban wilds. They do all the things vegetation and permeable surfaces and wildlife do for you anywhere - all those ecosystem services, cognitive and health benefits, views out your back door. We take them for granted, because we don’t see them, remember? But should they vanish, we’d notice the effects. We’d feel the loss. Better to notice and value what they do for us before that time comes.

Opportunity | Crisis: Adding microgrids to public urban infrastructure

11/2/2015

 
Coming next week to a symposium near you: an interdisciplinary conversation about what's new, what's needed, and what to do about public infrastructure in urban neighborhoods. I'll be chairing this session and moderating the discussion, as well as presenting about public perception of infrastructure. Hope to see you there! (Registration link below).

Infrastructure
has many connotations - public crisis, essential service, architectural buzzword - but also encompasses innovations like broadband and community microgrids. In older urban neighborhoods, political realities and lack of open space force infrastructural interventions to share public rights-of-way, spaces crowded above and below ground and home to many competing uses, such as all-weather transportation and street life. Dialogue and synergy between these many interests are  crucial to financially feasible plans to make urban neighborhoods vibrant and attractive places to live and work. Presentation topics will include public perception of neighborhood infrastructure, green infrastructure in public rights-of-way, the Syracuse I-Team initiative, and community microgrids for neighborhoods.

    About

    Assorted drafts, previews, and outtakes from the book I'm currently writing about the impact of vegetation and neglect on urban life. I also take other thoughts for a test drive here, including nascent design and research ideas.

    City Wild carries on the discussions and spirit of my 2011-2014 class, City Wild Seminar. This began as a forum for websites, articles, and other intriguing stuff sent to me (Susan Dieterlen) by current and former students, colleagues, and other well-wishers.
