Last year, ASLA celebrated World Landscape Architecture Month (WLAM) with the theme “Life Grows Here” in the places and spaces that landscape architects create in communities around the world. This year, ASLA is building on that success with our new campaign: Growing Together.
ASLA’s vision is “healthy, beautiful, and resilient places for all.” This April, we will show how landscape architecture projects embody that vision in all communities — communities of all colors, socioeconomic backgrounds, and abilities. We want to highlight how the spaces landscape architects create promote and facilitate people growing together with each other and with nature.
Keeping in mind restraints like the ongoing pandemic, this year’s campaign is designed to be flexible and versatile and focused on diversity in the landscape architecture profession.
ASLA members, landscape architects, and the public can participate by:
And as part of this year’s World Landscape Architecture Month, ASLA is also teaming up with EarthDay.org to sponsor The Great Global Cleanup 2021. ASLA members and the public can organize and join local cleanup projects as part of the effort.
Now in its third year, the Great Global Cleanup is building on its record as the world’s largest coordinated volunteer event, providing opportunities for individuals and organizations to make positive, tangible impacts on our environment.
Emerging from the coronavirus pandemic and guided by updated safety protocols, the collective goal this month is to remove millions more pieces of trash from our green spaces, urban communities, and waterways.
“Pollution is a prodigious issue in public open spaces — causing flooding, spreading illness, contaminating water sources, and at the root of a myriad of other problems,” said Torey Carter-Conneen, CEO of ASLA.
“Plastic and other types of pollution challenge every community every day,” said Kathleen Rogers, EarthDay.org President. “They are contaminating our oceans, clogging our drains, causing floods, spreading disease, transmitting respiratory infections, and killing wildlife; and low-income communities suffer the worst impacts. Thank you to ASLA for joining our efforts to restore our natural and urban landscapes.”
The goal is simple: as many local, pandemic-conscious cleanups as possible.
Organize a cleanup: We’re hoping every ASLA chapter can host at least one cleanup in April, but any member can take the lead. When organizing a cleanup, be sure to comply with all federal and local safety and health guidelines related to COVID-19.
To mark Frederick Law Olmsted’s 199th birthday, Olmsted 200 is inviting everyone to participate in a special two-part event — a viewing of Olmsted and America’s Urban Parks, narrated by actress Kerry Washington, and a panel discussion with landscape architects and park directors from around the country.
Stream the film for free at your leisure from April 24 to 25 and then join Olmsted 200 via Zoom on April 26 at 5:30 pm EST for a discussion on Olmsted’s thinking about today’s social, environmental, economic, and health challenges. TIME Magazine’s senior correspondent for climate, Justin Worland, will moderate.
Dr. Thaisa Way, FASLA, Resident Program Director for Garden and Landscape Studies at Dumbarton Oaks
Happy Haynes, Executive Director of Denver Parks and Recreation
Justin DiBerardinis, Director of FDR Park, Philadelphia Parks and Recreation
This event is hosted by the National Association for Olmsted Parks (NAOP), the managing partner of Olmsted 200. ASLA is one of ten founding partners of Olmsted 200, the bicentennial celebration of the birth of Frederick Law Olmsted (FLO).
April 26, 2022, marks the 200th birthday of FLO— author, journalist, public official, city planner, and father of American landscape architecture—and Olmsted 200 is teaming up with organizations across the country to celebrate him all year long.
Olmsted and his successor firms designed thousands of landscape projects across the country, transforming American life and culture. His vision of public parks for all people — and their ability to strengthen communities and promote public well-being — are now more important than ever.
Through events, education, and advocacy at the local and national levels, Olmsted 200 ensures that Olmsted’s legacy lives on by renewing public and policy commitments to the preservation and maintenance of our historic parks and places.
We hope you’ll use Olmsted 200 as a resource to find parks near you, share your stories, and celebrate with us.
Moving the Workplace Outdoors — 03/29/21, Metropolis
“‘There is an increased value of outdoor space as a result of the pandemic,’ said Zan Stewart, associate principal landscape architecture, Perkins&Will. ‘Central Park in New York and the grand boulevards of Paris both emerged from pandemics. Our teams can be happier, healthier and more productive with access to nature.'”
Rooted in St. Louis: The Creation of a Campus Forest — 03/29/21, Student Life: The Independent Newspaper of the Washington University in St. Louis “The diversity on campus speaks for itself––it is a testament to great landscape design that you do not notice all the work and planning that went into it. Yet the design behind the campus landscape, and its hidden mechanics, are as impressive as the results.”
WXY Reveals a Sustainable Master Plan for Downtown Davenport, Iowa — 03/16/21, The Architect’s Newspaper
“The Downtown Davenport Partnership (DDP) commissioned the New York-based WXY, Chicago real estate consultants SB Friedman Development Advisors, and New York City engineers Sam Schwartz Engineering to draw up a path toward downtown resiliency that would also spur economic development.”
Imagine a tool that banishes the social and environmental ills of modern urban planning and its suburban sprawl, instead constructing an approach that reconciles urbanism and environmentalism. Meanwhile, the tool also enables choice and equity in how and where individuals live.
Architect, urban designer, and DPZ CoDesign principal Andrés Duany insists such a tool exists. It’s the Rural-to-Urban Transect, at once a tool and a theory, and it’s a balm to the recklessly sprawling modern life now ubiquitous across the U.S., which takes the form of socio-economic uniformity, automobile dependence, and conspicuous land consumption.
This transect identifies and allocates elements of urbanism and their suitability to varying environments. It’s a theory of human settlement: an “ordering system” that harnesses a geographic gradient to organize natural habitats, including human habitats. Every human activity, and its resulting element in the urban fabric, can be pegged to a locus somewhere along that gradient. These elements comprise an “interrelated continuum of natural and human habitats—natural, rural-sub-urban, and urban—with different settlement densities and opportunities for social encounter and human activity,” the authors write.
Though the concept of a transect was not defined as such until the 18th century, Duany describes it as a pattern of human settlement both timeless and cross-cultural: the rural-to-urban spectrum can be traced to settlements from ancient Pompeii to ancient China.
In the late 18th century, Alexander von Humboldt first articulated the transect in the modern sense. Joseph Meyer illustrated the concept, drawing Humboldt’s voyage to South America to include the natural habitat and conditions above and below the ground’s surface.
In the 19th century, Sir Patrick Geddes’ illustrated “Valley Section” incorporated human presence in varying habitat zones. The humans, per the times, always exploited their environment.
In 1969, Ian McHarg posited the next seminal transect. Duany finds it incomplete: it failed to include, or even suggest, human habitat. Moreover, this absence perpetuated the dualism between human and nature that underpins environmental thinking — “nature is sacred, and the city profane.” This dualism ultimately produced the chasm between environmentalism and urbanism.
In practice, McHarg-inspired planning has yielded countless communities that prioritize preserved “environmental” areas at the expense of higher density. For example, South Carolina’s Hilton Head and California’s Sea Ranch sanction only single-use zoning. “The developed areas of these projects remain, in their socioeconomic and environmental performance, indistinguishable from sprawl: everyone drives everywhere for everything,” Duany and Falk write.
In 1994, the transect was revitalized as an ordering system at the Congress for the New Urbanism (CNU), when the group — proponents of “density, connectivity, and contiguity” — sought a theory establishing connections between elements of urbanism. The Rural-to-Urban Transect did so by defining six recognizable transect zones and their interrelationships: Natural (T1), Rural (T2), Sub-urban (T3), General Urban (T4), Urban Center (T5), and Urban Core (T6).
Duany asserts that the Rural-to-Urban Transect extends “the environmental protocol of McHarg into the city,” thus including people. It becomes a tool with which to design, correlating elements along a rural-to-urban continuum, enabling “the basis for a system of zoning that creates complex, contextually appropriate human environments.” Adapted from landscape ecology, each of the six transect zones contain elements that engender and amplify a place’s character.
This transect’s extension of the McHargian protocol yields arguably two of its greatest boons: its potential to unite environmentalism and urbanism and its capacity to support diverse, equitable communities. The divide between humans and nature is not new — Duany traces this chasm back to the Old Testament — and it manifests in the 20th century as environmentalism’s defensive stance toward urbanism.
The dominant ecological disposition “privileges a pristine nature and regards the presence of humans as a disturbance” to a system understood according to its pre-human condition. “A good human community can be ‘green’ only by being invisible,” Duany and Falk argue. Urbanism has thus been viewed as “a negative condition, never as an organization of positive choices for the improvement of human communities.” And as a result, environmentalism is expressed in technical and regulatory systems that promote suburbanization — from pervasive landscaping to mandated on-site stormwater treatment.
This paradigm fails communities when prioritizing nature means seeing “social space as blight.” “Whole communities of humans have been pushed aside for highway construction, but certain fish and fowl have caused even the most single-minded transportation department officials to reconsider their designs,” Duany and Falk contend. But only certain communities get pushed aside. Favoring nature also usually translates to favoring certain social and racial groups at the expense of others.
According to the authors, their Rural-to-Urban Transect can mitigate these insidious tendencies. Rather than holding economy and culture as beyond nature, this transect accommodates all elements, rooted in the belief that humans are essential to environmental discourse, in all their various lifestyles along the rural-to-urban spectrum.
Most importantly, Duany and the other authors include everyone in their conception and explicitly those who historically have had little choice in how they live. Systems based in the Rural-to-Urban Transect encourage a plurality of viewpoints and human habitats. They promote equity.
Key to the Rural-to-Urban Transect is its basis in form. Many planning initiatives are based in use and therefore manifest as prohibitions and separation. Cities filter community-making through a sieve of engineering standards, zoning ordinances, and other regulatory mechanisms long before designers enter the scene. Duany asserts that this existing framework, however, can be re-imagined by their transect: zoning based in form can yield certain physical outcomes and settlement patterns. Rather than zones that simplify and separate, transect code ensures fruitful relationships and adjacencies, from the local to regional scale. Transect-inspired zones preserve character and diversity according to place.
Essays in Transect Urbanism explain how these successes of the transect can be achieved: one details how to analyze an urban transect, one discusses governance along the transect, another discusses retail models within it. Duany includes a chapter describing the transect-based SmartCode that he has developed and implemented across various cities. Another chapter gives hope that existing sprawl can be repaired into a paradigm more resilient. Other essays consider the Rural-to-Urban Transect ontologically: the reason for six zones, and whether it qualifies as natural law, as certain people — Duany included — claim. The range of essays, from the practical to the theoretical, and the extensive illustrations make it a book suited for the student and the professional, for the planner, the landscape architect, and others thinking critically about the built environment.
As of 2019, the Form-Based Codes Institute identified 439 transect-based codes that had been adopted worldwide. Clearly, more communities do not embrace such thinking than do, and our society has much work to accomplish before divorcing itself from suburban sprawl. Duany in part blames the theory of landscape urbanism, which he claims perpetuates sprawl through the guise of aesthetics. He argues: “human biophilia is such that an image of anything with leaves will tilt the selection in its favor.”
Certainly, though, criticisms of the Rural-to Urban Transect arise: it is too simplified; its mere six zones are insufficient to account for all settlement and natural area types; the intentional rules of its zones are undesirably prescriptive; or it lacks consideration of urban ecology and biodiversity.
Yet, as made by the case presented in Transect Urbanism, the Rural-to-Urban Transect can serve as a noble tool in the reformation of our urban fabric. In one of his essays, written in 2005, Duany warns that a failure to square environmental ethos and social equity concerns with free market choice as perpetuated by the status-quo sprawl may only be solved by “a long economic emergency…that none of us should wish upon the nation.”
As millions of Americans grapple with job and home losses, among many other kinds of loss, we’re in the midst of an emergency. Released into a pandemic climate that has made us skeptical of dense urbanism, this book arrives with special urgency.
Now is as ripe a time as ever to give a different paradigm a chance, even if doing so will also require specific and convincing accommodations to the moment.
19th century sanitation engineer George E. Waring, Jr. was a miasmaist. He believed in the miasma theory, which holds that toxic vapors emanated from damp soil, rotted vegetation, and pools of standing water. These toxic vapors were understood to be created by the Earth and interact with the atmosphere and cause disease in American cities.
According to Catherine Seavitt Nordenson, ASLA, a professor of landscape architecture at the Bernard & Anne Spitzer School of Architecture at the City College of New York, Waring was a “marginal figure,” but he had interesting ideas about how to “modify the climate to improve health.” In a virtual lecture hosted by the Harvard Graduate School of Design, Seavitt Nordenson said Waring was incorrect about the mechanisms for spreading disease — he didn’t understand the concept of vectors, like mosquitoes — but his drainage and sanitation solutions were “surprisingly successful.” A year into the coronavirus pandemic, it’s worth revisiting Waring’s ideas about the connections between the Earth, atmosphere, disease — and the maintenance of public spaces.
Waring wrote numerous books, created the drainage plan for Central Park, and later became an influential sanitation commissioner of New York City. Born in Pound Ridge, New York, in 1833, he studied agricultural chemistry. In his early 20s, he wrote a book on scientific farming that explored “atmospheric and molecular matter, the interchange of Earth and air,” Seavitt Nordenson explained. He called for “mechanical cultivation to reduce water in soil” through the use of “thorough under draining, deep disturbance of the soil, and trenches.”
Because of this book, he was later hired by former U.S. presidential candidate Horace Greeley to create a drainage system for his farm in Chappaqua, New York. At his estate, Waring created an elaborate herringbone-patterned drainage system that directed water to streams, with the goal of improving the marshy soil for farming, but he would soon also use for eradicating imagined wet soil-borne disease.
Later, in 1857, Waring apprenticed as a drainage engineer with Egbert L. Viele, who had previously created a comprehensive survey and study of Manhattan, examining the marsh, meadow, and constructed lands of the island. The study included the land that would make up the future Central Park, a land that had been home to the freed Black community of Seneca Village, which was later cleared by the city government to make way for the park. Waring’s early drainage studies of Manhattan informed the many entries submitted as part of a design competition for the new Central Park.
In 1858, Waring was promoted to drainage engineer by landscape architect Frederick Law Olmsted and architect Calvert Vaux, who won the design competition for Central Park. Waring created an elaborate drainage system for the park landscape, which included low-lying wetlands. Waring had found favor with Olmsted. “Olmsted too was a miasmaist. Draining the park was framed as disease suppression.”
Considered the largest drainage project of his time, Waring designed a comprehensive system that directed water to constructed lakes and reservoirs. By 1859, the lower part of the park had been drained through a series of ceramic tubes buried deep into the soil that piped water directly to streams and ponds. “There was a mechanical movement to the low points,” where water would flow to.
With the onset of the Civil War in 1861, Olmsted left his position at Central Park and became executive secretary of the U.S. Sanitary Commission, where he was charged with reducing the death rate from disease for 8,000 sick and wounded soldiers. Olmsted created field hospitals in places he thought free of dangerous miasmas. Meanwhile, Waring resigned from Central Park work to become a major and lead cavalry in the Civil War.
After the Civil War and the publication of his book Drainage for Profit, Drainage for Health, Waring took up a post in Memphis, Tennessee, a city that had suffered severe epidemics of cholera and yellow fever, killing some 5,000 people in 1878 alone. While Waring didn’t understand the mosquito was a key disease vector, his plan for attacking standing water in building basements and streets had a positive effect on reducing disease. His comprehensive plan to separate the conveyance of stormwater and sewage, which was eventually implemented by the city, ended the health crisis.
Upon returning to New York City as sanitation commissioner, Waring applied his miasma theory to cleaning up the streets of the city. At the time, horses were leaving millions of pounds of manure and urine on the streets each day. Horse corpses were also left to rot. Garbage piles ran feet-deep and were cleared by ad hoc groups of unemployed.
Seavitt Nordenson thinks Waring elevated street cleaning and maintenance into a “performance,” targeting garbage as contributing to disease and declining morals. Taking a “militaristic approach,” he hired an army of sanitation workers that he dressed in all white. Nicknamed the “white wings,” they were given hand carts and brooms and also took on snow removal.
Waring would lead parades on horseback, with thousands of sanitation workers in army formation marching down the street. “It was a triumph of sanitation.”
After leaving the sanitation department of New York, Waring was dispatched to Havana, Cuba, by President McKinley to help solve their yellow fever epidemic. Until 1902, the U.S. had a colonial presence in Cuba, and American soldiers were dying of disease. While establishing Havana’s department of street cleaning, Waring contracted yellow fever from a mosquito. A day after his return to New York, he died, his remains quarantined on an island in New York Harbor.
Seavitt Nordenson said the legacy of miasmaists like Waring and Olmsted is the public health focus on the air — the intermixing of atmosphere and Earth. While Waring was a “brilliant failure” in terms of his scientific theories, a “great mind but incorrect,” Seavitt Nordenson also wondered: was he right?
During the pandemic, everyone has become a miasmaist to a degree, imagining the invisible droplets we know are floating in the air.
Seavitt Nordenson is currently completing a book on this topic with the University of Texas Press, with support from the Graham Foundation and the Foundation for Landscape Studies.
Hirshhorn Museum Is Close to Finalizing Hiroshi Sugimoto’s Garden Revamp — 03/12/21, The Architect’s Newspaper
“Sugimoto’s design will be only the second comprehensive update of the Washington, D.C. museum’s Gordon Bunshaft-designed campus, which debuted in 1974. Bunshaft’s garden, as well as its extensive 1981 renovation, was influenced by Japanese landscape architecture and garden design.”
The New Trend in Home Gardens—Landscaping to Calm Anxiety — 03/12/21, The Wall Street Journal
“Loud hues don’t cultivate serenity. ‘Reds, oranges and yellow are hot colors that stir passion,’ said New York landscape architect Edmund Hollander, who recommends mining the other end of the spectrum for tranquility. ‘The gradation of blues into greens is almost the colors of a stream, with whites and creams representing movement, if you will.'”
The Hirshhorn Sculpture Garden Redesign: Paving Paradise — 03/11/21, The Wall Street Journal
“The Hirshhorn Museum’s Sculpture Garden in Washington is nearly perfect; of course, it must be destroyed. This is the paradox of landscape architecture: The more sensitive and subtle the garden, the more invisible it is—even to its custodians. At a certain point they can mistake it for an opportunity to exploit rather than a sacred trust to protect.”
The Bike Boom Is Real, Says New Mode Share Data — 03/05/21, Greater Greater Washington
“Since 2007, the share of people in the Washington region who ride bikes has gone up, while driving and riding transit have dropped, according to a gigantic once-per-decade report.”
What About Jane? – 03/03/21, Urban Omnibus
“Jacobs’ legacy is divided. On the one hand she should be seen as an analyst of gentrification, not simply a harbinger of its ill effects. But she also treats with kid gloves the social phenomenon that has made gentrification such an urgent topic today: race.”
AARP is once again offering its Community Challenge Grants, which range from a few hundred dollars up to tens of thousands, to non-profit organizations and local governments. AARP seeks to fund permanent or temporary small-scale projects that can be designed and implemented in just a few months. This year, the focus is on projects that support community equity, diversity, and inclusion efforts.
Landscape architects and designers, please take note: AARP is prioritizing projects that “improve open spaces, parks, and access to other amenities; and deliver a range of transportation and mobility options that increase connectivity, walkability, bikeability, wayfinding, access to transportation options, and roadway improvements.” They are also interested in projects that support community recovery from the coronavirus pandemic.
Since 2017, AARP’s program has awarded 560 grants totaling $6.1 million, which have resulted in rapid-fire actions that improve community livability for all ages — not just older adults. 60 percent of grants have gone to 501(c)(3), 501(c)(4), and 501(c)(6) nonprofits, and the rest to local governments. 42 percent of grants have gone to urban communities, 38 percent to rural areas, and 20 percent to suburban areas.
According to AARP, 45 percent of grants have had a catalytic impact, helping grantees gain additional funds and support from public and private organizations. And 81 percent of grants helped grantees “overcome policy barriers and advance change.”
The American Society of Landscape Architects (ASLA) released its Racial Equity Action Plan – a Five-Point Plan to continue the process of eradicating the systems and structures within the landscape architecture profession and larger design community that have resulted in limited opportunities and recognition of the deserving Black, Indigenous, and People of Color (BIPOC) professionals who’ve led and produced important, ground-breaking, and honorable work.
“ASLA and its members reject bigotry and racism in all its forms, and anti-Black racism in particular, as wrong and fundamentally inconsistent with our mission and values,” said Torey Carter-Conneen, CEO of ASLA. “ASLA is putting that conviction into action. ASLA is in the business of changing the world through the art and science of design. Our Five-Point Racial Equity Plan of Action is the next progression of our journey together.”
The plan sets actionable goals and benchmarks for the organization and for the landscape architecture profession. These include:
ASLA’s Smart Policies for a Changing Climate Online Exhibition demonstrates how landscape architects are designing smart solutions to climate impacts, such as flooding, extreme heat, drought, and sea level rise. 10 new projects added to the exhibition exemplify best practice approaches to landscape architecture in the era of climate change.
The projects include a mix of landscape-based and often nature-based solutions across the U.S., which range in scale from residential and school landscapes to master plans for entire cities and counties. There is also a focus on projects that address climate injustices and meet the needs of historically-marginalized and underserved communities.
“The projects clearly show how landscape architects can help all kinds of communities reduce their risk to increasingly severe climate impacts. Landscape architects design with nature, which leads to more resilient solutions that also improve community health, safety, and well-being over the long-term,” said Torey Carter-Conneen, ASLA CEO
With the new projects, which were selected with ASLA’s Climate Action Committee, there are now a total of 30 projects featured in the online exhibition. Each project was selected to illustrate policy recommendations outlined in the 2017 report produced by ASLA’s Blue Ribbon Panel on Climate Change & Resilience.
Being solely dependent on cars increases communities’ risks to climate impacts. Through the 815-mile Cuyahoga Greenways Framework Plan created by landscape architects and planners at SmithGroup, some 59 communities will have healthier and more resilient transportation connections to downtown Cleveland, Lake Erie, and each other.
Too few schools offer educational green spaces that can spark children’s appreciation for nature, which is critical to helping them become future Earth stewards. Jane Tesner Kleiner, ASLA, with nature+play designs partnered with school leaders, students, and volunteers to design native plant gardens, meadows, and tree groves that create environmental education opportunities; support pollinators, such as butterflies, bees, and birds; and also manage stormwater.
By 2012, more than 50 percent of the tree canopy of the Houston Arboretum and Nature Center had been lost due to drought and hurricanes made more severe by climate change. By removing trees and restoring the original prairie, savannah, and woodland ecosystems found at the Arboretum, landscape architects with Design Workshop and Reed Hilderbrand designed a landscape naturally resilient to future climate shocks.
Historically marginalized and underserved communities, like those found in the South Side of Chicago, are disproportionally affected by climate impacts such as flooding. Through the Space to Grow program, a flooded asphalt schoolyard at the John W. Cook Academy, an elementary school on the South Side, was redesigned by landscape architects at site design group, ltd (site) to become a green learning and play space that captures stormwater.
Through their research capabilities and campus infrastructure, universities and schools can also help solve the climate crisis. For the Kendeda Building for Innovative Sustainable Design at the Georgia Institute of Technology in Atlanta, Georgia, landscape architects with Andropogon integrated an innovative water management system that captures and reuses 100 percent of stormwater runoff from the building and also cleanses and reuses building greywater in the ecological landscape.

Climate change has severely reduced the availability of fresh water in arid Western states. Turf lawns require vast amounts of water to maintain and also provide no habitat for native plant and animal species. Through NatureScape, an innovative program in Orange County, California, Jodie Cook, ASLA, helped homeowners transform their turf front yards into water-saving native plant gardens that can sustain a range of native bird, bee, and butterfly species.
Climate change is making communities’ struggles with aging combined sewer systems, which carry both sewage from buildings and stormwater from streets, even worse. With more frequent extreme weather events, these systems now more often overflow, causing untreated sewage to enter water bodies. Rain Check 2.0, an innovative program in Buffalo, New York, led by landscape architect Kevin Meindl, ASLA, offers grants to private landowners to capture stormwater through trees, rain gardens, green roofs and streets.
Historically marginalized and underserved communities, like those in the South Bronx in New York City, experience higher than average heat risks because they typically have fewer parks and recreational spaces. The lack of safe and convenient pedestrian and bicycle access to nearby green spaces exacerbates the problem. Working with two community groups and the New York City government, landscape architects with MNLA designed the Randall’s Island Connector, a ¼-mile-long multi-modal path underneath an Amtrak freight line.
Sapwi Trails Community Park
Thousand Oaks, California | Conejo Recreation & Park District and RRM Design Group (consulting landscape architects)
In drought-stricken Western states, climate change has added stress to increasingly fragile ecosystems. Instead of moving forward with an earlier plan that could have damaged the Lang Creek ecosystem, planners and landscape architects at the Conejo Recreation & Park District and RRM Design Group designed the Sapwi Trails Community Park to be a model for how to preserve ecological systems while improving access and dramatically reducing water use.
Climate change and environmentally-insensitive development in the Pacific Northwest are exacerbating negative impacts on salmon. Grassroots environmental organizations sought to daylight the piped Thornton Creek. A new water quality channel was designed by landscape architects at MIG to clean stormwater runoff from 680 surrounding acres before the water flows into the South Fork of the salmon-bearing Thornton Creek.
New projects were submitted by ASLA members through an open call ASLA released in 2019. In partnership with the ASLA Climate Action Committee, projects were selected to represent a range of U.S. regions, scales (from residential to county-wide master plans), and firm types.
In 2017, ASLA convened a Blue Ribbon Panel on Climate Change & Resilience, which resulted in a report: Smart Policies for a Changing Climate and a series of lectures and educational sessions at built environment conferences. In 2019, an exhibition outlining 20 cases that exemplify the policy goals outlined in the report opened at the ASLA Center for Landscape Architecture in Washington, D.C., and a companion website was launched.
The exhibition was funded in part by a grant from the National Endowment for the Arts (NEA).
Highways and elevated train and subway lines that cut through cities can be seen as barriers. But through innovative landscape design, the spaces beneath these transportation systems are becoming new linear parks that help bring communities back together. Offering built-in shelter for rain and snow and shade during warmer months, elevated infrastructure provides communities and landscape architects an opportunity to create new forms of public space.
After more than six years of planning, design, and construction, the first half-mile-long segment of The Underline, Miami’s 10-mile-long linear park, has opened below the city’s Metrorail system. Designed by a multidisciplinary team led by James Corner Field Operations (JCFO), a landscape architecture and urban design firm, The Underline is a model for how to separate pedestrian and bicycle networks and incorporate exercise facilities and outdoor spaces — all while leveraging existing infrastructure.
When The Friends of the Underline, a non-profit organization, and JCFO complete the project, the new park will span from the Miami River in Brickell to the Dadeland South Metrorail station and create more than 120 acres of multi-use public space. Restored natural habitats will mix with public spaces of all kinds along with pedestrian and bicycle paths that link directly to the Metrorail’s stations.
The first segment is already a far cry from what was once there. Isabel Castilla, ASLA, design principal-in-charge for The Underline at JCFO, said: “I still remember one of our first site visits when we had to strategically run between oncoming traffic to cross the street because there was no safe way to cross the SW 7th or SW 8th Street intersections!”
Through outreach sessions, Castilla’s team discovered that improving pedestrian and bicycle access below the Metrorail lines was a priority for the community. “We learned there was a strong desire to create separate paths as some cyclists wanted to travel fast while using The Underline for commuting while others desired a space for strolling,” she said.
To reduce conflicts between pedestrians and bicyclists, JCFO implemented a few strategies: “First and foremost, we added traffic lights, pedestrian signals, and crosswalks. Second, the path geometry is always straight and perpendicular to intersection crossings in order to ensure cyclists have proper visibility.”
Furthermore, “all intersections feature designated crosswalks for pedestrians and cyclists in order to give room to everyone and minimize conflicts. Lastly, we implemented bold pavement graphics — not only at intersections to make drivers aware of those crossing on bike or by foot, but also along the bike path to alert cyclists of an upcoming intersection so they can reduce speeds,” Castilla explained.
For Alejandro Vazquez, ASLA, design project manager for The Underline at JCFO, the project’s transportation safety benefits are personal: “My grandparents lived in Little Havana and their street didn’t even have a sidewalk to walk on. I remember my grandfather being one of the few people riding a bike in Miami in the 80’s and 90’s, and we were always worried that he would get hit by a car. In a county that has the highest number of pedestrian and bicycle crashes in the state of Florida, the simple act of creating connections through Miami with The Underline’s safe bike trail and pedestrian paths is quite revolutionary. The Underline and its connections to the Metrorail, Metromover, bus transport system, and projected trails—including the future Ludlam trail and the Miami Riverwalk extension—will contribute to a robust network of sustainable mobility corridors.”
The Underline has also become part of the greater East Coast Greenway, which runs 2,900 miles from Maine to Florida. Phase one of The Underline links with the Miami River Greenway, and the completed linear park will connect to six major trails in Miami-Dade county.
Beyond the street-level transportation network, JCFO incorporated a range of public spaces, all designed with a bold green brand identity and way-finding system designed by Hamish Smyth of Order Design. Brickell Backyard, the first phase of The Underline, found at the northernmost portion, is organized into a “procession of rooms” — the River Room, Gym, Promenade, and Oolite Room. Many of these spaces will also eventually be populated by public art, selected in collaboration with Miami-Dade County Art in Public Places.
The River Room offers views of the Miami River, native and South Florida-friendly plants, and space for residents and their dogs.
The Gym is designed for fitness, with a flexible court for basketball and soccer surrounded by exercise spaces that have strength training equipment, stretch and balance areas, and a running track.
The Promenade area, which includes the multi-modal Brickell Metrorail station, features wide sidewalks for bus and trolley commuters, a pedestrian path, and a separate bike path between the Metrorail columns that increases safety, JCFO notes.
Social spaces in the Promenade include a Station Grove, which offers moveable tables and chairs and bicycle parking for commuters; a game area with tables for chess and dominoes; a 50-foot-long communal dining table; and a plaza and stage that hosts activities organized by the Friends of the Underline.
The Oolite Room, named after the Oolite sedimentary limestone of Miami that naturally compresses into ooid forms, frames native plant gardens designed to attract butterflies.
Castilla explained that The Underline is found in the monarch butterfly migration corridor. “The park has already seen a resurgence of butterflies that include the Atala butterfly, an endangered endemic South Florida species that thrives with plants such as Coontie and Lantana involucrate,” she said.
As Miami faces climate impacts such as extreme heat, sea level rise, and increased ground-up flooding through its limestone landscape, the entire project was also designed to be climate resilient.
To reduce heat gain, Castilla tells us “the project is carefully designed around existing mature trees to preserve them while also carving out sizable new planting areas, minimizing hard surfaces, and, in turn, minimizing heat gain. All hardscapes use light-colored materials. In particular, the bike path asphalt paving was coated with a light-colored finish.”
The landscape architects also made sure the project did its part to reduce flooding from stormwater. “The Underline corridor sits on the Miami Rock Ridge, benefiting from some of the highest elevations in Miami.
