The American Society of Landscape Architects (ASLA) is now accepting proposals for the 2020 Conference on Landscape Architecture in Miami, Florida, October 2 – 5, 2020.
The ASLA Conference on Landscape Architecture is the largest gathering of landscape architects and allied professionals in the world—all coming together to learn, celebrate, build relationships, and strengthen the bonds of our incredibly varied professional community.
We seek education proposals that will help to drive change in the field of landscape architecture and solve everyday challenges informed by research and practice.
Help us shape the 2020 education program by submitting a proposal through our online system by Thursday, January 23, 2020at 11:59 p.m. PT.
More than 100 education sessions and field sessions will provide attendees with the opportunity to earn professional development hours under the Landscape Architecture Continuing Education System™ (LA CES™). Many of the sessions will also qualify for continuing education credit with the Green Building Certification Institute (toward SITES AP and LEED AP credential maintenance), the American Institute of Architects, the American Institute of Certified Planners, and other allied professional organizations and state registration boards.
Education session speakers selected from this process will receive a full complimentary registration to the 2020 Conference on Landscape Architecture.
“The idea that big data will be the generator of design in the future is very depressing,” said Elizabeth Boults, ASLA, a landscape architect and educator, at the ASLA 2019 Conference on Landscape Architecture in San Diego. She instead called for “alternative methods that incorporate a more spiritual perspective.”
With her husband Chip Sullivan, FASLA, a professor of landscape architecture at the University of California at Berkeley, who is a passionate proponent for honoring and designing with the unseen forces that shape landscapes, Boults outlined how one method that sounds a bit woolly at first — tarot cards — can actually be a thoughtful design tool for understanding the genus loci (spirit of place), which is so central to landscape architecture.
Boults believes that landscape architecture is a mix of art and science. Art relates to the “mysterious, non-linear, subjective” process of design, while science is about “rational structures, categories, and typologies.”
Beyond art and science though, there is also the spiritual aspect of landscapes. “Across cultures, people shape landscapes based on their beliefs.” Many cultures have had “gods and goddesses who are guardians of the spirit of places.” For example, Romans believed each home had a genius, who were honored through a shrine.
Prehistoric peoples were attuned to the “atmosphere, the flora, animal life, and geological formations; they listened to the trees, wind, and moon.” Boults wondered: “Are we still listening today?”
Enduring ancient beliefs are still alive and well in modern practices such as Feng Shui in China, Vastu Shastra in India, and landscape cosmologies among Native people and across many cultures. Within these cultural approaches to the landscape, it’s always important to “consult the genus loci of a place before starting a design process.”
Sullivan then steered the lecture towards the use of tarot cards, which he had previously “never paid attention to.” But then one day he began to wonder, “what are they about? When we have our cards read, what are we putting our value in?”
Examining historical and contemporary decks, he discovered they are “all about the landscape,” with their “Pre-Raphaelite imagery that compresses natural information.”
During a studio project with his students to define core landscape design principles, he discovered what they were creating were essentially tarot cards, depicting sacred archetypal elements like the tree of life, the enchanted forest, the well. His students then began using the tarot decks in order to actively divine new designs; the result were “amazing.”
Like conventional decks, the genus loci tarot laid out core elements such as “the journey of the hero, the call to adventure, facing trials and tribulations, finding resolution, crossing the threshold, and achieving enlightenment.” Sullivan believes people are attracted to tarot cards because they depict life as a journey.
He also believes it’s no coincidence that tarot cards and mysticism are so popular in highly creative Silicon Valley, which is home to companies like Oracle (another sacred symbol).
In the last third of what was one of the most unusual and fun ASLA conference sessions ever, Sullivan and Boults offered glue, collage materials, watercolors, pens, and index cards so that attendees could create tarot cards depicting their own conception of genus loci.
Two attendees from different parts of the room realized they drew the nearly-exact figure of a wellspring, the source of life, showing that natural archetypes remain real in our disconnected digital world.
Whether you are looking for the perfect gift for your favorite landscape architect or an immersive read for yourself, explore THE DIRT’s top 10 books of 2019, our picks for the best on the environment, cities, and landscape:
These are two useful and beautiful books on how to design with trees. The Architecture of Trees — first published by Cesare Leonardi and Franca Stagi, two versatile Italian furniture, landscape, and architectural designers, in 1982 and now reprinted in 2019 — features 212 trees species depicted through 550 intricate quill-pen illustrations, each drawn to 1:100 scale. The Tree Book, written by arboreal guru Michael A. Dirr and Keith S. Warren, director of product development for the tree nursery J. Frank Schmidt and Son Co., includes images, botanical and common names, and the range and climate adaptability of some 2,400 species and cultivars. Read the full review of The Architecture of Trees.
This vivid collection of comparative maps and tableaux from the 19th century, organized by French researchers Jean-Christophe Bally, Jean-Marc Besse, Phillipe Grande, and Gilles Palsky, show how explorers, scientists, and artists imagined fantastical landscapes in order to better understand the true scale of the natural world. Their drawings and paintings laid the foundation for today’s geographical data visualizations.
Jeffrey Peterson, who was recently senior advisor responsible for climate change policy at the Environmental Protection Agency (EPA)’s office of water, has written a comprehensive new national policy approach to dealing with sea level rise, a roadmap for reforming the U.S.’s broken flood insurance system and steering development away from increasingly risky coastal areas.
At the ASLA 2019 Conference on Landscape Architecture in San Diego, former Environmental Protection Agency (EPA) administrator Gina McCarthy argued that telling the story of the dangerous health impacts of climate change will motivate greater public action to reduce greenhouse gas emissions. Air pollution, which causes the premature death of 7 million people worldwide each year, will only worsen with climate change. As Tim Smedley explains in Clear the Air and Beth Gardiner in Choked, the solutions to the climate and air pollution crises are largely the same: renewable power, clean cook stoves, electric vehicles, and green infrastructure.
Design with Nature Now is an accessible and well-designed companion book to the University of Pennsylvania’s Design with Nature Now symposium and exhibition, which marked the 50th anniversary of Ian McHarg’s seminal book Design with Nature. Edited by Frederick Steiner, FASLA, Richard Weller, FASLA, Karen M’Closkey, and Billy Fleming, ASLA, this collection of essays and projects should inspire any environmental policymaker, planner, or landscape architect to forge broader coalitions and act regionally and globally to save our fragile ecosystems and protect the future of humanity.
Designing a Garden, written by Michael Van Valkenburgh, FASLA, is a lucid and candid examination of the process of designing and constructing a single intimate project. Van Valkenburgh intends the book as a sort of how-to guide to landscape design, not unlike a cookbook in terms of detail and clarity. Read the full review.
An expanded and updated new edition of a now-classic book that launched the New Perennials movement, fundamentally changing landscape design. Edited by Noel Kingsbury, the book features the works and writings of High Line plant designer Piet Oudolf and late plantsman and designer Henk Gerritsen.
Journalist Tony Horwitz’s book on Frederick Law Olmsted is difficult to classify. It is a biography of Frederick Law Olmsted and a history of his America. It is also reportage from rural America and a thoughtful reflection on our times. Read the full review.
Buying these books through THE DIRT or ASLA’s online bookstore benefits ASLA educational programs. And if you are based near Washington, D.C. we also recommend checking out the National Building Museum’s fantastic book store.
Walter Hood Digs Deep – Architectural Digest, 11/18/19 “The Oakland, California–based landscape designer, fresh off a string of prestigious design prize wins, has an approach that embraces the eccentricities of people and place.”
Dreaming Up Disneyland – The New York Times, 11/25/19 “Those who knew Walt Disney often described him as an uncomplicated man of conventional 20th-century sensibilities: a lover of model trains, farm animals, lunch-wagon food, hard work, evening belts of scotch and endless Chesterfield cigarettes. One of his rituals upon coming home from his movie studio was feeding his poodle, Duchess, a cold frankfurter, or “wienie,” by leading her from room to room while throwing pieces on the floor.”
A survey of homeless individuals by Downtown Streets Team yielded one overwhelming response: they felt completely ignored as human beings. At the ASLA 2019 Conference on Landscape Architecture in San Diego, Brian Elliott, policy analyst for San Diego Councilmember Chris Ward; Brandon Davis with the California-based Downtown Streets Team; and Lena Miller with Urban Alchemy, discussed strategies to reintegrate homeless individuals into their communities, ranging from top-down policy decisions to empowering local unsheltered populations through employment options.
California is ranked number 1 in homelessness, with nearly 130,000 homeless individuals, according to the U.S. Department of Housing and Urban Development (HUD), and numbers only continue to rise.
Elliott expressed a commitment to reduce the number of unsheltered people in San Diego County, which he cited as at least 4,476 people, nearly 55 percent of the at least 8,100 homeless residents of San Diego County. Councilmember Ward is the chair of the Regional Task Force on the Homeless, an “integrated array of stakeholders committed to preventing and alleviating homelessness.”
Dispelling myths about who the homeless was paramount to all three speakers, but Elliott highlighted that in San Diego, the cause is primarily economic. He noted that “a hospital bill they could not pay, a utility bill they could not pay, balanced with housing, especially in a high-cost market with low vacancy rates, leads to homelessness.”
The City of San Diego unanimously passed the Community Action Plan on Homelessness, a body of policy focused on helping the existing homeless population, preventing future homelessness, and ensuring that homelessness is an experience that is brief and non-recurring. Davis made clear that “homelessness is an experience, not an identity.”
The plan looked at three short-term goals to be achieved in three years: end youth homelessness; end veterans homelessness; and decrease unsheltered homelessness by 50 percent. Building community and state level buy-in is central to achieving these goals. As can be seen below, veterans homelessness spreads across generations.
The first step of the plan calls for transitioning away from using the police as a first point of contact and instead reaching out to social workers. In order to combat the housing issue, the city council has committed to at least 140 new units of permanent support housing in all 9 council districts to be built over two years. To achieve this, Elliott encouraged landscape architects to continue to design for everyone, not specific populations.
Miller started Urban Alchemy in 2018. The organization birthed out of Hunter’s Point Family, an earlier non-profit Miller founded that focused on public housing.
Miller became interested in public toilets, specifically their importance in ensuring the dignity of the homeless, but also their potential for jobs. The organization has created 24 safe and clean public toilets in Tenderloin and other parts of San Francisco with high homeless populations and given homeless individuals jobs cleaning and maintaining those toilets, BART stations, the Civic Center area, downtown streets, and parks.
Urban Alchemy works with long-term offenders, integrating them back into society in order to prevent them from experiencing homelessness. Miller pointed to their high levels of emotional intelligence, their ability to read people, and their ability to interact with different kinds of people. All of these skills help them to establish and maintain social norms in the public places they work.
The police are brought in to offer deescalation training, helping to establish a relationship between law enforcement and employees of Urban Alchemy. Miller said this “transforms the paradigm of how the police see us, and how everyone in society sees us.”
Miller noted how the work provides not only an income but also a sense of pride, remarking on an anecdote where one employee called the Governor of California into a bathroom stall he had just cleaned to show him how clean it was.
Urban Alchemy saved 85 lives in 2018, through Narcan deployment, which brings back people from drug overdoses, and providing water to dehydrated people.
Downtown Streets Team employs local homeless populations to clean community spaces in San Jose and San Francisco. Instead of an hourly wage, they offer a non-cash basic-needs stipend, case management, employment services, and a support network within their community. The program offers people who have been out of work for a few years a platform to build their resume and eventually re-enter the workforce.
Volunteers wear bright yellow shirts, denoting them as members of the community and part of the Downtown Streets Team. The simple action of donning a yellow shirt and cleaning the community restores their dignity as people and members of their community.
The marginalization of homeless individuals often leads them to ignore the social norms of public space. Including them as part of the community helps ensure norms are met.
Each Tuesday, Downtown Streets Team hosts a town hall where people can participate in public life, share in each other’s successes, and be together. For Davis, “we are all here to hold each other accountable to be our better selves.”
To date, Downtown Streets Team has secured over 1,900 jobs and homes for people.
Landscape architects need to become urban planners and work “upstream” in policy and regulatory processes to ensure public space leads urban placemaking efforts. That is the argument Michael Grove, ASLA, chair of landscape architecture, civil engineering, and ecology at Sasaki; Brian Jeneck, ASLA, director of planning at HOK; and Michael Johnson, ASLA, principal at SmithGroup made at the ASLA 2019 Conference on Landscape Architecture in Washington, D.C.
Grove linked the current misalignment between public space and private development to the long history of “decoupling policy making and placemaking.” Urban planners have led in the policy and regulatory-making realm while landscape architects have proven expertise in placemaking.
Landscape architects can instead lead and participate in urban policy-making through “upstream urbanism” while prioritizing public spaces as the dominant placemaking strategy in cities.
To illustrate the importance of this approach, Jeneck discussed the typical block structure of San Francisco, which is 360 feet by 360 feet, as it relates to floor area ration (FAR), or the amount of building area in relation to the size of a lot.
A four-story building occupying 50 percent of the site would have a floor area ratio of 2, which Jeneck notes is on the low end for urban development. Assuming the lot is the entire block, the dimensions of this building would be 180 feet by 360 feet, a footprint with an impractical amount of interior space.
This undesirable set of dimensions for a building can result in design teams creating assemblages of towers, which to achieve the same FAR could take up 70 percent of the site, greatly limiting public space. Developments like this happen because policy makers haven’t accounted for public space corridors and connections from the beginning.
The speakers set out five scales in which urban design takes place: regional plans, city general plans, city area plans, city-specific plans, and project plans.
Landscape architects are intimately familiar with the project scale, but need to shift up in scale towards the regional plan, affecting policy that begins to shape the form of the city.
Scaling up gives landscape architects a larger role in designing the broader framework in which smaller urban, area, and project plans must exist, a crucial role the profession is currently lacking.
According to Johnson, landscape architects’ ability to work with complex systems makes them a natural choice for managing the goals that must be met at each scale.
He gives the example of a set of scalar jumps, 1, 10, and 100. 1 is the site scale, the place landscape architects are currently most comfortable, 10 is the city scale, and 100 is governance and public policy.
All presenters looked at lessons from past planning movements in order to inform what a future landscape architect-led planning framework could look like.
They traced the history of Ebenezer Howard’s Garden City and the influence of Frederick Law Olmsted and Daniel Burnham on the City Beautiful Movement. While the Garden City and the City Beautiful movements were highly influential, they were also ensnared in class politics, giving them a green veneer without truly being equitable.
Cities account for 3 percent of our land area, but 80 percent of global greenhouse gas emissions. Getting the next generation of urban planning and design right is imperative.
Revitalizing post-war plazas requires a deep understanding of the historical significance and degree of integrity of the existing conditions, which to Charles Birnbaum, FASLA, president of The Cultural Landscape Foundation, can then “guide the level of intervention and level of surgery that one is applying to the bone structure.”
Birnbaum provided a framework for how to measure success that operates on two axes: historical significance and integrity.
Historical significance relates to the importance of the plaza culturally, both locally and within the landscape architecture canon, while integrity focuses on the condition of the original design and implementation.
To demonstrate how the graph works, Birnbaum located three plazas within it: Peavey Plaza in Minneapolis (high significance and high integrity); Boston City Hall Plaza (medium significance and medium integrity); and Love Park in Philadelphia (low significance and low integrity).
Birnbaum then defined seven aspects of integrity for plazas:
Location: Place where the plaza is constructed. Setting: Physical environment around the building. Design: The form, place, materials, and structure of the plaza. Materials: What the plaza is constructed with. Workmanship: Physical evidence of the construction and craftsmanship of the plaza. Feeling: Quality and often intangible elements that constitute a place. Association: Historical and cultural ties to the plaza.
Birnbaum used his methodology to categorize Mellon Square in Pittsburgh, Pennsylvania (high significance and medium-high integrity); Lever House Plaza in New York City (high significance and medium integrity); Time-Life Building in Chicago (medium-high significance and medium integrity); and Nollen Plaza in Des Moines, Iowa (medium-low significance and low integrity), prefacing the case studies Rademacher and Smith detailed.
Rademacher explained how Mellon Square had maintained its integrity for many years after its construction but lost its character after an integrity-reducing reconstruction in the 1980s.
The 2007 update, led by the Pittsburgh Parks Conservancy and implemented by Heritage Landscapes, aimed to restore Mellon Square to its original design, eliminating several of the changes that occurred during the 1987 reconstruction.
Rademacher laid out a few of the problems that came up with the restoration. Fountain function was dependent on a worker being present. Planting was overgrown or dead. And “most egregious was a redesign of the fountain” that led to a new double crenelated edge, which divorced the timing of the water feature from the original design and its intent.
Many of the materials were preserved in the 1987 reconstruction, but recreating the major elements of the plaza would be central to the 2007 reconstruction. The fountain was the most difficult piece to return to its historical character, with the original slow contemplative rhythm of the fountain being at odds with contemporary thought about how fountains should perform. Ultimately, the team decided on a flashy program on the hour and the slower contemplative program for the remainder of the time.
Returning the plaza to its original design was important for it to retain its integrity and to maintain its historical significance for the City of Pittsburgh.
Smith elaborated on three projects that his firm has worked on, each project approaching the historical legacy of plazas in different ways.
First, and the most historically significant, was the Lever House in New York City (see image at top). Smith’s team relied on a set of photographs by Ezra Stoller to recreate the plaza in lieu of many architectural drawings for the plaza space.
Stoller photographed the project during construction, upon completion, and for several years after the project was finished. This helped Smith to understand the changes throughout the first few years of the project, particularly in planting and usage. The analysis resulted in a near-identical reconstruction of the space.
The Time-Life Building plaza features a distinct terrazzo patterning that carries through into the building’s lobby, which is the only part of the building complex that is part of the historic registry. The tile patterning was then paramount to the design of the plaza. Smith’s team recreated the terrazzo look in concrete. The major change was relocating the fountain to “reframe the plaza relative to the sidewalk,” creating a connection between the Avenue of The Americas and the plaza.
Cowles Common’s, formerly Nollen Plaza in Des Moines, Iowa received the most change while retaining the tilted orientation of the plaza in relation to the street grid.
Major changes included eliminating a wall separating the north and south sides of Des Moines, the addition of a new fountain feature in the center stripe of the plaza, and the installation of a new sculpture by Jim Campbell.
Each of the plazas hold some level of historical significance as post-war plazas, but as Rademacher and Smith noted, the measure of the success is not dependent on the funds spent on the projects, but on identifying and enhancing the spirit of the places.
Malda focused on three ways that GGN uses drawing in their practice: “drawing out, drawing in, and drawing together.” He was quick to question landscape architects’ proclivity to create drawings at a resolution that exceed the resolution of information, noting “we are putting more information in than we actually have.”
In contrast to the ubiquitous Google Earth photos, which are commonly used to quickly understand a place, Malda highlighted a drawing by Keith McPeters of GGN that pulls out the topography and road infrastructure as a means to understand what is important to the place. “It is as much about what is not drawn as what is drawn.”
In a similar vein, Batts discussed integrating technology, namely tablets, into his drawing process as a way to quickly and iteratively test ideas over photographs taken on the device or downloaded from Google Earth.
The capabilities of drawing apps allowed him to subdue information and call forth and alter elements of the existing site with speed and ease. In many ways, the digital surface acts as a digital form of trace paper. He joked that this is the “Power of the Apple Pen.”
All emphasized the variability of drawing styles and types. There is a place for exploratory or abstract drawings investigating materials, form, and ideas, as much as for representational and observational drawing. The trio emphasized that different types of drawings are necessary to think through different stages and processes during design development.
For Gray, drawing is a form of thinking. He realized early on in his life that “because I could draw, I could help solve problems.” Drawing is now a way of extracting an idea from his mind using the hand, a process that is instrumental to exploring thoughts quickly without being burdened by crafting the perfect drawing.
Malda noted that 40 quick sketches of different ideas can be produced in a fraction of the time it would take to produce a finished rendering.
Iterative drawing can also be taken into client meetings, a technique Olin highlights in the video interview, and all speakers highly encouraged during their talks. Gray and Batts emphasized the power of the pen to forge connections between clients, but also with people of different cultures.
Gray draws with clients in real-time, on-site if possible, allowing them to explore ideas together. This can help bring out local knowledge of the place. Real-time drawing in charette processes allow the community and the designers to inspire each other.
Batts echoed the power of drawing as inspiration through an anecdote about a trip to a small village in Mexico. Each evening they set up a craft table, which brought together villagers who didn’t have access to these materials, while Batts sketched the local landscape.
A local man named Joel was curious about Batts’ sketches, and finally asked, through a translator, if Batts could teach him to draw perspective, which was a new view of his familiar landscape. This moment reveals drawing’s potential: its ability to “transcend disciplines, language barriers, and cultures.”
A few decades ago, when you thought of Orange County in California, “you didn’t think of the citrus growing here, you thought of the color of the sky,” said Gina McCarthy, former administrator of the Environmental Protection Agency (EPA), at the opening general session of the ASLA 2019 Conference on Landscape Architecture in San Diego.
Air pollution grew worse and public pressure increased on government at all levels to solve the problem. Then, finally, in 1970, the Clean Air Act was passed, and the Environmental Protection Agency (EPA) was formed. Since then, “air pollution has been reduced by 75 percent, while we have tripled gross domestic product (GDP).” This led McCarthy to state: “So don’t tell me solving climate change is beyond our reach.”
The technological side of fixing the climate crisis — renewable energy, a clean power grid, electric vehicles — are easy to envision and within reach. “The clean energy train has left the station, and there’s no way it’s turning back.”
The harder problems to solve are the greenhouse gas emissions from the built environment, and the “loss of the sense of community.” The solution to both problems is to build communities that can be “the foundation for a more sustainable tomorrow.”
Sustainable communities create opportunities for children to get outside and play, which is why McCarthy was one of the first to create a No Child Left Inside program in Connecticut when she served as commissioner of environmental protection.
When McCarthy was commissioner, she remembered meeting school children in Hartford who lived a few miles from the Connecticut River, but had never seen it. “No one drove them there.” And “there was no green space to connect them to the river.”
“How can children love nature if they don’t see it? How can they become the next environmental stewards if they don’t care about nature?”
To achieve sustainable communities, green infrastructure must also be interwoven throughout the built environment. “By moving away from concrete pipes to green infrastructure, we can also make our cities finally look good again.”
McCarthy called for “transforming the built environment to integrate nature into everything.” For this, she said landscape architects play a crucial role, as they are experts on how to design with nature.
Landscape architectural solutions like urban forests and green roofs will reduce the impacts of extreme heat. “Heat stress will kill more people than all other climate impacts put together. Heat is a silent killer — it kills people in their homes and on the streets.”
McCarthy believes “climate change is the most significant public health, security, economic, and environmental challenge of our time.” And all progress made on the environment and climate change under the Obama administration is now under assault.
While some 92 percent of EPA regulations formulated under the Obama administration withstood legal and other challenges, “all our life-saving efforts to reduce air and water pollution and clean-up contaminated sites are under attack.”
Still, she found hope in the fact that some 25 states and hundreds of cities have stated they are still abiding by the terms of America’s contribution to the agreement. Together, this coalition of states and cities represents 55 percent of the U.S. population. If this group were a separate country, it would the third largest economy on Earth.
Regardless of party, “Americans want a stable, clean environment in which they can live, work, and play. I’ve worked under six governors, five of which were Republicans, and not one said to me, ‘we really need more pollution.'”
And that is why the attacks on environmental regulations are particularly galling for her. “The EPA really isn’t an environmental agency; it’s a public health agency. The EPA is focused on fewer asthma attacks and heart attacks.”
Phasing out dirty power sources like coal in favor of clean, renewable energy means cleaner air. In the U.S. some 4,000 kids develop asthma each year. “If you have seen a child having an asthma attack, you never forget it.” And thousands die prematurely from bad air quality.
Climate change is also about people’s health, perhaps more than nature. “No one relates to glaciers. What they relate to is the health and well-being of their children and grandchildren. Health is the best way to get people to care about climate change. Communications must be personal, and health is incredibly personal. Focusing on health impacts will create action.”
She exhorted the crowd of landscape architects to fight the good fight: “Do not sit on the couch. Stop being angry and anxious. Taking action is what being adult is all about. And we must demand action. We can’t turn our backs on our children and grandchildren.”
“Stop following the latest dramas in Washington, D.C. The Beltway isn’t the real world. Have you ever heard of an innovative idea that was initiated at the Federal level?”
She urged landscape architects to “speak up, challenge the status quo, and make your families proud. Design the future; show people what it looks like; tell the story.”
“We need landscape architects to design a world that is healthy, safe, and beautiful — and more just. Landscape architecture can kindle hope in all of us.”
