During the Sui dynasty, it took a decade for master craftsman Li Chun to build the Anji stone bridge in southern Hebei province. Some 1,400 years later, Tsinghua University robotics professor Xu Weiguo copied the structure in just 19 days, with the assistance of robots 3D printing in concrete. The resulting engineering marvel — an 86-feet-long, 12-feet-wide bridge in the Boashan district of Shanghai — uses a single load-bearing arch, just like Anji.
Robotic arms swung back and forth for some 450 hours, fulfilling the demands of their algorithms. The robots were programmed to follow separate models of the arch structure, fence, and deck, yielding some 176 uniquely-shaped pieces, which were then slotted into place.
The hyper-real, curvilinear, machine asthetic of many 3D modeled objects is also found in this bridge. On the deck, a brain coral pattern filled with fine stones add some warmth, bringing the feel of traditional Chinese garden path.
According to Tsinghua University, the 3D printed bridge costs just two-thirds the price of a bridge produced the conventional way.
Professor Xu and his team at the Tsinghua University School of Architecture’s Zoina Land Joint Research Center for Digital Architecture (JCDA) tested the bridge design using a 1:4 scale model to ensure it would bear the weight of pedestrians. And for extra safety, they built in a real-time monitoring system. Wires and sensors embedded throughout the structure send a constant stream of data on the performance of the bridge.
Pier 4 ‘Sea Steps’ in Seaport District Opening This Summer– Curbed Boston, 1/22/19
“The five so-called Sea Steps next to the future Pier 4 luxury condo complex and the Institute of Contemporary Art area in the Seaport District are expected to open this summer, according to developer Tishman Speyer.”
OLIN Designing a 400-acre Waterfront Park for Southern Indiana– The Architect’s Newspaper, 1/28/19
“OLIN has been tapped to design a 400-acre park along the northern shore of the Ohio River in southern Indiana. Set within a swath of waterfront long-occupied by landfill and industrial facilities, the future park will give local residents a much-needed connection with the river and its history, while boosting the area’s link to Louisville, Kentucky.”
Home Buyers Want Outdoor Spaces — and They’re Willing to Pay for Them– The Tennessean, 1/29/19
“Outdoor features of all kinds, from pools to fireplaces to complete living rooms with furniture designed to stand up to the elements, are being installed in backyards everywhere, said Joe Raboine, a manager for Belgard. The company provides materials and design services.”
Landscape Architecture Coalition: We Need More Walkable Streets– Associations Now, 1/30/19
“Smart Growth America, which focuses on improving infrastructure around the country, recently released a study highlighting the scope of dangers that pedestrians face due to metropolitan areas not being built for walking. The study was produced in tandem with its subsidiary, the National Complete Streets Coalition.”
In Detroit, twelve arts, cultural, and educational institutions are clustered together geographically, but have failed to form a unified district, a true destination. The Detroit Institute of Arts (DIA) and the Midtown Detroit Inc, hope that a new central public space around the DIA and a broader urban design to boost connectivity and accessibility can change that. In an attempt to create a coherent, inclusive, accessible, and sustainable district that can attract both residents and tourists, DIA and Midtown launched an international design competition last year, which has since yielded three finalists that presented to some 200 local residents at the DIA last week.
More than 40 submissions from 10 countries were narrowed down to eight finalists. And now it’s down to three interdisciplinary teams led by landscape architecture firms: Agence Ter from Paris, France; Mikyoung Kim Design from Boston, Massachusetts; and TEN x TEN, which is based in Minneapolis, Minnesota.
According to the DIA and Midtown Detroit, Inc, who worked with the twelve educational and cultural institutions, the finalists’ proposals are the result of a year of input from committees and residents, which participated through 40 public engagement sessions.
Finalists presented to the competition jury at the DIA, which includes Salvador Salort-Pons, president of the DIA; Maurice Cox, Detroit’s planning director; and landscape architect Julie Bargmann, ASLA, founder of D.I.R.T. Studio.
All the teams seek to shrink down the width of boulevards; remove parking; add event spaces, cafes, and public art installations; and vastly expand public green space. The new designs could be the National Mall of Detroit or a lush, interactive university campus. The design teams seek to bring people in from around the Detroit and the suburbs and keep them there, engaged, enlightened, and entertained year-round.
The Agence Ter team offered meandering paths through forested and planted areas, with experimental event spaces for local artists and public art installations that speak to Detroit’s unique history.
The Mikyoung Kim Design team envisioned a verdant space, with a central lawn that can host events, as well as an outdoor movie screen, cafe, playground, and maze garden that converts into an ice rink in winter.
And the TEN x TEN team proposed a more angular, contemporary design, with green space but also “fog gardens,” an “exploratorium,” and interactive light graffiti wall.
An exhibition of the proposals is on view at the DIA until April 1. The winning proposal will be announced by the end of April.
This incredible investment in raising Detroit’s profile as a cultural mecca can only help this city get back on its feet after years of disinvestment and near bankruptcy. Only a few years ago, the city seriously considered selling off the amazing art at the DIA to pay down debt. The message of this project is inclusive cultural and ecological revitalization is the new way to do urban revitalization.
For thousands of years, humans have purposefully immersed themselves in forests in order to revitalize their spiritual, mental, and physical health. But in 1982, Tomohide Akiyama, director of Japan’s forestry agency, put a name to this, coining the term shinrin yoku, which can be translated as forest bathing. Since then, interest in the practice has skyrocketed among both the public and scientific researchers. And last year, forest bathing may have hit a tipping point, with four books published around the world on this natural therapeutic approach. Forest bathing seems poised to go global, as interest expands beyond Japan into South Korea, the rest of Asia, and throughout the West.
In Shinrin Yoku, The Japanese Art of Forest Bathing, Yoshifumi Miyazaki — who is a professor at the Chiba University center for environment, health, and field sciences; coiner of the term “forest therapy;” and one of the first to conduct scientific research on the health benefits of forest immersion — we have the original Japanese take on the practice.
In Japan, forest bathing and the more-regimented, often multi-day practice of forest therapy are mainstream. Companies regularly send their employees to forests to restore themselves. And Japanese go on therapeutic vacations to some of the most well-known sites of natural beauty. Today, there are some 60 official forest therapy trails, designated for the practice of shinrin yoku by the Forest Therapy Society. And there are a growing number of doctors who are certified to practice forest medicine.
Over the course of human evolution, we have spent 99.99 percent of our development in natural environments. It’s only very recently that we have, as a species, moved into dense urban areas. According to Miyazaki, this has resulted in major health issues. “We are over-stimulated and stressed by today’s man-made world, and that makes our bodies more susceptible to disease.” For him, “it’s not surprising that attention is turning to shinrin yoku as an example of a natural and low-cost way to alleviate this problem.”
In 1990, Miyazaki conducted some of the first experiments to examine the physiological effects of forest bathing on the Japanese island of Yakashima. The study had limited value because then only saliva samples measuring cortisol levels were used. Since 2000, though, the science “moved on,” yielding new ways to measure brain activity and autonomous nervous activity, “both good indicators of the level of stress in the human body.” Over the past 10-15 years, data on the benefits of forest bathing has accumulated.
Miyazaki does an excellent job of clearly communicating the dangers of stress and how forest therapy helps reduce its impacts.
Our over-stimulated urban lifestyles leads to chronic stress, which is exacerbated by “technostress,” the unique stress caused by our fixation on smart phones, twitter feeds, and Netflix accounts.
According to Miyazaki, stress causes illness such as the common cold; back, neck, and shoulder pain; slower healing; weight gain and loss, sleep dysfunction; depression; dysautonomia (autonomic nervous disorder); irritable bowel syndrome; ulcers and stomach problems; heart diseases; and increased cancer risks.
Forest therapy increases physiological relaxation, boosting our immune system and undoing the damaging effects of stress.
The benefits of forest therapy measured by Mizayaki and others include:
“Improvement of weakened immunity, with an increase in the count of killer (NK) cells, which are known to fight tumors and infections.
Increased relaxation of the body due to increased activity in the parasympathetic nervous system activity.
Reduction in blood pressure after only 15 minutes of forest therapy.
Reduced feelings of stress and a general sense of well-being.
Reduction in blood pressure after 1 day of forest therapy, which lasts up to 5 days after therapy.”
On a deeper level, Miyazaki believes we experience these benefits when we de-synchronize with technology and the stressful pace of urban living and re-synchronize with the natural rhythms we have evolved with. Over seven million years of human evolution, “we have lived amid nature and our bodies have adapted to that nature.”
In Japan, there is a deep connection with nature. From the country-wide festivals under the beautiful, ephemeral cherry blossoms to the prayers left at the base of honored tree specimens, Japanese live with nature, as opposed to admiring it as the other. People and the natural world co-exist in a country still covered in nearly 70 percent forest. It makes sense then that the Japanese government invested greatly in research on forest therapy, some $4.3 million since 2004.
One study was conducted in 63 forests across Japan, using some 756 subjects, who were split into 6 groups in different regions. Within each group, half went to urban areas and half were sent to forested areas. Subjects were asked to walk slowly through an urban or forested environment for 15 minutes in the morning, and then just sit and look at the view for 15 minutes in the afternoon. Their autonomic nervous activity, pulse rate, blood pressure, cortisol levels were measured, and they were asked questions about how they felt. The study proved that “during forest therapy, the body experiences physiological relaxation.” And subjects in the forested areas reported an increased feeling of comfort, calm, and refreshment; an improvement in their emotional state; and reduction in anxiety.
Other studies in Japan showed that a forest therapy session reduced blood pressure among men with high blood pressure and office workers; calmed pre-frontal brain activity; and among mature women, reduced stress levels. Furthermore, if a forest isn’t accessible, spending time in a large urban park, looking at ornamental house plants, flower arrangements, or bonsai trees, or smelling wood also relaxes the body.
The book is also worthwhile as a guide to shinrin yoku on your own. Miyazaki explains how to walk mindfully in the forest, feeling the forest floor, taking in the sounds and smells, or closely studying a tree. For a therapeutic boost, he recommends meditating, stretching, or sketching in a forest.
Other notable forest bathing books published in the past year:
An astonishing 6,000 pedestrians were struck and killed by vehicles in 2017, adding to a deadly decade in which 49,340 people were killed on the nation’s streets between 2008 and 2017. Compounding this national tragedy, victims are disproportionately from vulnerable groups, including people of color, those living in low-income communities, Native peoples, and the elderly.
Nancy Somerville, Hon. ASLA, the executive vice president and CEO of ASLA, welcomed the study, saying, “Too often, danger is built right into our nation’s streets, especially in communities with large elderly populations and people of color. Strong policies are needed that will allow landscape architects to continue to put good street design to work to reduce unnecessary risks and make sure our transportation systems equitably serve all Americans. As cities begin the process of rebuilding and reimagining our decaying urban infrastructure, pedestrian safety must be among our highest priorities.”
Somerville added that “The landscape architecture profession plans and designs streetscapes across the country and welcomes this opportunity to direct the attention of the public and policymakers to this deadly daily crisis. Landscape architects are devoted to improving the health, safety, and welfare of every community, and urge the creation of federal, state, and local policies that will correct the tragic inequities that are built into our nation’s aging road systems.”
Using the most recent federal data from the Fatality Analysis Reporting System, the study generates a Pedestrian Danger Index that ranks each state and the 100 most populous metropolitan areas on how deadly they are for people on foot. It also reveals the degree to which vulnerable groups face disproportionate danger and higher risk of death and injury.
Smart Growth America is hosting a public briefing online about the report findings on Thursday, January 24, at 2:30 p.m. EST.
Electric scooters have become a familiar sight throughout the country. Dotting street corners in tidy rows in the mornings, placed haphazardly outside office buildings after the lunch hour, and zipping down streets and sidewalks at all hours of the day, electric scooters are fast becoming a ubiquitous feature of the urban landscape. The rapid expansion of electric scooters has drawn both support and criticism. By understanding the pros and cons of electric scooters and various regulatory considerations, landscape architects and urban planners can help cities make the most of this significant private investment in the public realm.
The potential benefits of incorporating electric scooters into a city’s transit infrastructure are substantial. Leading electric scooter companies, such as Bird and Lime, tout their products as an alternative non-vehicular means of transportation, a zero-emission people-moving mechanism that can reduce short distance single-occupant car trips. Commuters who use public transportation for the bulk of their commute and who cannot or do not wish to use a bike for the final distance to the office can avoid a taxi or ride share trip by hopping on a nearby electric scooter. As many scooter riders will tell you, electric scooters also have the benefit of being fun to ride. Tourists are a major subset of electric scooter riders, as they enjoy the ability to see a new city at a leisurely pace without breaking a sweat.
Renting an electric scooter for a ride isn’t quite as simple as hopping on and zipping off. Riders must first download each company’s app using a smartphone. The app shows locations of nearby scooters that are currently unoccupied and ready to be checked out. Typically, scooters are placed in neat rows in groups first thing in the morning, after being charged overnight. Later in the day, scooters may be distributed in more irregular groups as they are ridden and parked in various places by the riders. First-time users of an app also need to enter a credit card for payment (entered one time then used for all subsequent purchases, similar to the way the Uber and Lyft apps work), and a photo of a driver’s license to verify age.
Critics have noted these requirements limit use across the socioeconomic spectrum; Washington D.C. is hoping to develop a method for cash payment. Rides are priced by the minute, timed from check-in to check-out using the app. Some apps also require riders take a photo of the scooter where it is stopped at the end of the ride, in order to record potentially-illegal parking practices used by some riders. Riders can expect to pay a typical fee of $1 to unlock the scooter, plus $0.15 per minute.
Electric scooters may have launched in California, but 2018 saw the trend spread across the country and throughout the world. With such exponential growth, many cities have multiple competing brands of scooters within the same area. Austin, Texas, has had such high rates of usage that scooter providers have needed to schedule mid-day servicing of their fleets to charge scooters’ batteries. The usefulness of scooters in urban settings and the potential to replace short car trips has increased enormous investment to electric scooter companies. Ford recently purchased Spin for nearly $100 million, while Uber has partnered with Lime.
The first of many regulatory challenges comes with the way a scooter company might choose to launch a fleet in a new city. Several companies initially gained the industry the reputation of “begging for forgiveness rather than first asking for permission” after launching electric scooter fleets without consulting city officials. This prompted San Francisco to temporarily ban all electric scooters, eventually offering two permits to electric scooter companies Skip and Scoot. Other cities issue permits to a certain number of total electric scooters, split among different providers.
If an electric scooter company approaches a city first to request permission to operate locally, how might a city respond? Some jurisdictions might be glad for the private investment in public transit and permit operation without caveats. Others, hesitant of the demands electric scooters place upon the public right of way, may take a different approach — as did New York City, when, considering the density of sidewalks and bicycle lanes without scooters, issued a firm “thanks, but no thanks” to scooter companies.
State regulations may also play a role in whether electric scooters must operate on city streets, sidewalks, or not at all:
To address safety concerns, electric scooter companies require all scooter riders wear helmets and meet a minimum age requirement. These requirements are frequently violated by users, as are regulations requiring scooters be ridden on the sidewalk, roadway, or in a bike lane. Conflicts between pedestrians, bicyclists, vehicles, and scooters are difficult to avoid without formally set and well-understood rules for where and how a scooter should operate. One particularly active period of reported scooter accidents in Austin, Texas, led the federal Centers for Disease Control (CDC) to partner with Austin city government to study the most common source of incidents. This study is currently underway, but Austin is already planning to put a safe riding ordinance into effect in the spring of 2019.
Electric scooter companies are beginning to put money and effort toward improving the safety of scooter riders. Bird scooters recently announced plans to form a Global Safety Advisory Board, led by the former head of the National Highway Traffic Safety Administration, with the goal of improving electric scooter safety. Bird has also proposed a funding strategy whereby $1 daily per vehicle in a city’s fleet would be dedicated to a fund for improving bicycle lanes and infrastructure in that city. Bird scooters currently offers cities data on usage within that city, which can be a valuable data metric in understanding the flow of people through the city, scoping a site pre-development, or for post-occupancy analysis.
Electric scooters can replace much more vehicular use, particularly single-occupant, short-distance car trips, in congested urban environments. At the same time, city management and planning authorities must carefully weigh the risks to public safety before approving electric scooter programs.
With clear rules and robust public awareness campaigns to ensure all users understand the rules for legal operation, scooters may come to safely co-exist with existing users of the public right of way. Electric scooters are here to stay, and cities have the opportunity and challenge of establishing a safe framework in which citizens and visitors can enjoy the full benefits of this technology.
CRÈME Proposes Floating Timber Bridge to Connect Brooklyn and Queens– The Architect’s Newspaper, 1/10/19
“Currently the only link between the rapidly developing neighborhoods of Long Island City, Queens, and Greenpoint, Brooklyn, is the Pulaski Bridge, a six-lane drawbridge with a narrow pathway where pedestrians and bikers jostle for space.”
As we look forward to covering new stories on the built and natural environments this year, here’s a look back at the 10 most popular DIRT posts of 2018. Readers were most interested in the debate over whether beauty still matters in an age dominated by science; how the practice of landscape architecture is evolving to deal with climate change and increasingly diverse communities; how urban sprawl is impacting biodiversity; and the interesting relationship between landscape architecture and retail. As in past years, new research on the health benefits of nature remains a favorite topic.
Always worth mentioning: We are looking for original op-eds, particularly from member landscape architects, designers, and planners, on topics that inspire you. And tell us about your new projects and research. Please email us at email@example.com.
Kicking off a two-day planting symposium at the University of California at Berkeley, professor emeritus Marc Treib posed the question: Is there still a place for the “art of landscape design” in an age “dominated by the science of landscape ecology?” Planting design is often brushed aside as superfluous or unserious. British historian and critic Tim Richardson reminded the audience of the litany of unfavorable adjectives associated with artful planting: the bourgeois, the small-scale, the amateur, the hobbyist, the ephemeral, the female.
If you are looking for a unique book to give as a gift or just one for yourself to delve into over the winter break, explore THE DIRT’s top 10 books of 2018, our picks for the best on the environment, cities, and landscape.
Instead of simply responding to catastrophe, Boston is getting out front on climate change. As part of its Climate Ready Boston plan, the city of 670,000 aims to act fast and protect two coastal neighborhoods most vulnerable to rising sea levels and storms: East Boston and Charlestown. New plans for these neighborhoods explain how a simple fix like creating a temporary flood wall at the coastal end of the East Boston Greenway, at a cost of just $100,000, would protect 4,300 residents, 70 businesses and critical infrastructure, and result in $17 million in benefits.
When a neighborhood floods, who is at fault? A class action lawsuit in Houston asks that question. The residents of a master-planned community that flooded during Hurricane Harvey are suing the engineering firm that designed the neighborhood’s stormwater management system. While that suit targets engineers, it nonetheless represents the heightened risk landscape architects face from climate impacts on their projects.
Cities are sitting on a largely underused public resource: urban stormwater wetlands. If properly designed, these landscapes can reduce flooding, support urban wildlife, and serve as public space. A new report Design Guidelines for Urban Stormwater Wetlands — authored by an interdisciplinary group of researchers and students at the MIT Norman B. Leventhal Center for Advanced Urbanism led by Celina Balderas Guzmán, Heidi Nepf, and Alan Berger — advocates for the positive role wetlands can play in cities and outlines research that provides insights for landscape architects, engineers, and planners.
Neurosurgeon Edie Zusman, a real-life Doogie Howser who started medical school at 19 and has completed some 6,000 brain and spinal surgeries, said what landscape architects do saves far more lives than what she does. The early prevention of disease reduces the need for surgeries. Prevention is made possible by eating healthy foods and walking and getting exercise in green environments that lower stress and improve well-being.
Trees are really essential for a competitive shopping district. There was a study by Kathleen Wolfe that indicated trees increase price elasticity by 9-12 percent. In other words, people feel comfortable paying up to twelve percent more for the same product if they purchase in a well-landscaped place with nice streets. Also, when properly located, street trees keep people in the downtown district longer. They feel more relaxed and are more likely to spend more money.
Participatory design is “hands-on democracy in action,” argue the editors of the impressive new book Design as Democracy: Techniques for Collective Creativity. Participatory design (also known as cooperative or co-design) is a process in which a designer actively involves all stakeholders in a design process. Unfortunately, many of the best-known techniques to enable this approach, which have been used for the past few decades, have become stale. This has led to complacency among designers, and less-than-ideal outcomes for communities that need their help. To revitalize the approach and achieve better results, the authors call for making participatory design “truly democratic.” Furthermore, it must become “contextual, open, experiential, substantive, and holistic.”
We experience “soft fascination” with nature when we sit on a park bench and let our mind wander, taking in the trees and flowers, noticing birds and squirrels, feeling the breeze. This gentle decompression in nature is actually critical to helping us restore our ability to pay attention. We need breaks where our minds can just go slack and subconsciously take in the complexity of the natural world. Researchers are still trying to figure out the ideal “dose” of this green medicine, but benefits have been seen with just 10 minutes.
In 2013, urban landscape historian Thaïsa Way, FASLA, embedded herself in the office of Gustafson Guthrie Nichol (GGN) in Seattle, Washington in order to understand the firm’s inner workings. That initial academic curiosity sparked a collaborative relationship, the remarkable result of which is GGN Landscapes 1999-2018, a compendium of GGN’s projects that interweaves theory and practice. The book sets a new standard for landscape architecture monographs.
It was the goal of both Way and GGN to improve upon the typical monograph, characterized by photos of finished, successful projects and not much else. Both parties were also wary of getting too much into the weeds of each project. GGN Landscapes struck that balance, presenting not only each project’s final design but its evolution, told through detailed written accounts and built upon by process sketches, models, and photos.
The book’s richness is the result of the access Way was granted at GGN. Way looked over shoulders, asked questions, and attended meetings. Details such as which team members led discussions, which incessantly sketched, and on what sort of paper were all taken note of. Way pored over working documents and memos to clients and consultants, seeking to understand how GGN made and maintained relationships. Not confined to the office, Way visited each of the book’s featured projects, accompanied by their respective lead designers (save for one instance in which that designer was unavailable). She stressed that this effort would have been impossible without the benefit of GGN’s trust.
Way’s research paints a picture of an especially collaborative firm that is interested in the intersection of analog and digital techniques and embraces experimentation. It’s worth emphasizing that many firms would claim these same traits. Way witnessed them at GGN. Her analysis is borne out in the book’s featured projects, all of which could stand alone as case studies.
The first project presented in the book, and perhaps GGN’s most famous, is Lurie Garden in Chicago. Way’s text tells the story of GGN’s involvement, from the project’s procurement through research, design, and resolution. The book describes the technical challenges encountered and thought process behind GGN’s decisions. Iterative sketches show variations on the garden’s iconic breastplate form and planting scheme. And, of course, there are plenty of photos that attempt to capture the power of the space (Way thinks that even GGN failed to foresee just how impressive Lurie Garden would become).
If the Lurie Garden chapter shows us a young firm getting a feel for itself, India Basin Shoreline Park, the book’s final featured project, shows a mature practice in full command of its faculties and with a firm grasp of landscape’s agency. Shannon Nichol, one of GGN’s three founders, led the concept design for the park in the Bayview-Hunters point neighborhood of San Francisco. The concept is, as Way describes it, “emblematic of 21st century design,” negotiating issues of environmental degradation, access to the water, historic preservation, and neighborhood revitalization. GGN’s concept includes a large meadow reminiscent of a patent slip that once existed on site. Included in the chapter are Nichols’ sketches showing the meadow’s origin in the concept, and a series of plans show its refinement over time.
The book also contains less project-oriented views into GGN’s process. Way believes understanding the designer is crucial to understanding their approach. As such, we learn how GGN’s founders came to landscape and their attitude toward design. We also learn of how their practice benefited early on from successful collaborations with outside architects and engineers and how this helped form their broad view of landscape architecture.
With GGN Landscapes, Way and GGN have constructed a monograph better suited for backpacks than coffee tables. I cannot think of higher praise.
